A review of the Icom IC-705 QRP Portable SDR Transceiver

The following review was first published in the February 2021 issue of The Spectrum Monitor magazine:


It sometimes seems that one of the biggest enemies of a radio enthusiast these days is RFI (radio frequency interference), which is to say, human-originated noise that infiltrates––and plagues––vast chunks of our radio spectrum.

Yet I believe RFI has, in a sense, also managed to energize––and even mobilize––many radio enthusiasts. How? By drawing them out of their houses and shacks into the field––to a local park, lake, river, mountain, woodland, or beach––away from switching power supplies, light dimmers, street lights, and other RFI-spewing devices.

Shortwave and mediumwave broadcast listeners have it easy, comparatively speaking. They can simply grab a favorite portable receiver, perhaps an external antenna, then hit the field to enjoy the benefits of a low-noise environment. In that a portable receiver is something of a self-contained listening post, it’s incredibly easy to transport it anywhere you like.

Ham radio operators, on the other hand, need to pack more for field operations. At a minimum, they need a transceiver, an antenna, a power source, not to mention, a mic, key, and/or computing device for digital modes. Thankfully, technology has begun miniaturizing ham radio transceivers, making them more efficient in the use of battery power, and integrating a number of accessories within one unit.

Case in point: in 2019 at Tokyo’s Ham Fair, Icom announced their first QRP (low-power) radio in the better part of two decades: the Icom IC-705.

Introducing the Icom IC-705

 

It was love at first sight among fans of Icom when the 2019 announcement was made. Why? The instant thrill came courtesy of the IC-705’s resemblance––in miniature––to the IC-7300, one of Icom’s most popular transceivers of all time. Not only that, but the IC-705 sported even more features and a broader frequency range than the IC-7300. What wasn’t to love?

But of course, unlike the IC-7300, which can output 100 watts, the IC-705’s maximum output is just 10 watts with an external 12V power source, or 5 watts with the supplied Icom BP-272 Li-ion battery pack. Nevertheless, enthusiasts who love field radio––this article’s writer being among them––were very pleased to see Icom design a flagship QRP radio that could take some portable operators to the next level. Power was traded for portability, and for field operators, this was a reasonable trade.

And since, again, the IC-705 has even more features, modes, and frequency range than the venerable IC-7300, I felt it important to note them up front. Here are a few of its most notable features, many of which are not available on its bulkier predecessor:

  • VHF and UHF multimode operation
  • D-Star mode
  • Built-in GPS
  • Built-in Wifi connectivity
  • Built-in Bluetooth connectivity
  • Portable size
  • Battery power

The receiver design is similar to the IC-7300 below 25 MHz in that it provides a direct conversion. Above 25 MHz, however, it operates as a superheterodyne receiver. While the user would never know this in operation, it’s a clever way for Icom to keep costs down on such a wideband radio.

At time of publishing, there are no other portable transceivers that sport all of the features of the Icom IC-705. It has, in a sense, carved out its very own market niche…At least for now.

I’ve owned the IC-705 since late September 2020, and I still haven’t fully explored this radio’s remarkable capabilities. It’s really a marvel of ham radio technology, and I’m having fun exploring what it can do.

One conspicuous omission

Let’s go ahead and address this promptly. The IC-705 does have one glaring shortcoming.  It lacks one feature that is standard on the larger 100-watt IC-7300: an internal antenna tuner (ATU).

To be frank, I was a little surprised that the IC-705 didn’t include an internal ATU, since it otherwise sports so many, many features. Not having an internal ATU, like a number of other general coverage QRP transceivers in its class, definitely feels like a missed opportunity. With an ATU, the ‘705 would truly be in a class of its own.

I’m sure Icom either left the internal ATU out of the plan due to space limitations––perhaps wanting to keep the unit as compact as possible?––or possibly to keep the price down? I’m not sure.  At release, the price was $1300 US, which is undoubtedly on the higher side of this market segment; at that price point, it might as well have included an ATU.

With that said, not having an internal ATU is still not a disqualifier for me. Why? Because I have a number of resonant antennas I can add on when in the field, a remote ATU at home, and a couple of portable external ATUs, as well. Yes, it would be helpful to have it built in––as on my Elecraft KX1, KX2, and KX3, or on the ($425) Xiegu G90––but for me it’s not a deal-breaker.

One other minor omission? A simple tilt stand or foot. I do wish Icom had included some sort of foot on the bottom of the IC-705 so that it could be propped up for a better angle of operation. Without a tilt stand or foot, the IC-705 rests flat on a surface, making its screen a bit awkward to view. Of course, a number of third-party tilt stands are available on the market. And if you have a 3D printer or access to one, you can find a wide variety of options to simply print at home. I printed this super simple tilt foot, which works brilliantly.

But why not include one, Icom?

My 3D printed tilt foot

But while the IC-705 lacks a tilt foot, it actually sports a number of connection points on the bottom, including a standard tripod mount. Thank you, Icom, for at least including that (other radio manufactures please take note)!

Initial impressions

Funny: the IC-705 is the first new transceiver I’ve purchased with a color box.

If you’ve ever owned or operated the Icom IC-7300, you already know how to operate many of the functions on the IC-705. The user interfaces on the touch screens are identical. Features that are unique to the IC-705 are easy to find and follow the same standard Icom user-interface workflow.

Having less front faceplate real estate, the IC-705 has less buttons than the IC-7300––about 11 less than its big brother, to be exact. However, the twin passband, gain, multi-function knob and encoder are in the same positions and layout as on the IC-7300.

And if you’ve never used an IC-7300 before, no worries: this is one of the more user-friendly interfaces you’ll find on a ham radio transceiver.

The build of the IC-705 is excellent. It’s not exactly hardened for the elements––there is no waterproof rating or dust rating, for example––but it gives the impression of a solid little radio, likely to withstand a bit of less-than-delicate handling. Yet even though it’s designed to be a portable field radio, I’ll admit that the front panel and especially the color touchscreen feel a little vulnerable. I do worry about damaging that touchscreen while the radio travels in my backpack.

The Icom LC-192

On the topic of backpacks, Icom released a custom backpack (the LC-192) specifically for the IC-705, Icom AH-705 ATU, antennas, and accessories. I did not consider purchasing this backpack, although I’m sure some operators would appreciate it, as it has dedicated compartments for supplies and the radio can be attached to the floor of the backpack’s top compartment. Again, I passed because I’m a bit of a pack fanatic and tend to grab gear that’s more tactical and weatherproof.

While its in my Red Oxx or GoRuck backpack, I house the IC-705 in a $14 Ape Case Camera insert. Eventually I want to find a better solution, but this does help pad the IC-705 while in my backpack and certainly fits it like a glove––hopefully protecting that touchscreen.

A number of third-party manufacturers have designed protective “cages” and side panels for the IC-705, but I’ve been a bit reluctant to purchase one because I feel they may add too much weight and bulk to the radio.

To the field!

Sandy Mush State Game Land

The day after I received my Icom IC-705, I took it to the field to activate Sandy Mush State Game Land for the Parks On The Air (POTA) program. Typically, when I review a new radio, I spend a few hours with it in the shack before taking it to the field. In this case, however, I felt comfortable enough with the IC-705 user interface, so I decided to skip that step entirely––I was eager to see if this little radio would live up to expectations.

The previous evening, I’d connected the IC-705 to my 13.8V power supply, so the BP-272 battery pack was fully-charged and attached to the IC-705. There was no need for an external battery to be connected.

[Tip: Click here to view my YouTube playlist of field activities with the IC-705.]

Getting on the air that day was very straightforward; indeed, the set-up couldn’t have been more simple: radio plus antenna. I connected the IC-705 to a Vibroplex EFT-MTR end-fed 40, 30, and 20-meter resonant antenna, thus an external antenna tuner was not required.

The Vibroplex/End-Fedz EFT-MTR antenna

Next, I plugged in the included speaker/mic, spotted myself to the POTA network, and started working stations. I asked for audio reports and all were very positive using only the default audio settings. Obviously, the small hand mic works quite well. I did quickly decide to unplug one of the two connectors of the speaker mic (the speaker audio side) so that the received audio wouldn’t be pumped through the hand mic, using the much better IC-705 front-facing speaker.

In the field that day, I had a few objectives in mind:

  • See how well the supplied hand mic works for SSB contacts, thus intended to ask for audio reports
  • Check out full break-in QSK operation in CW mode
  • Measure exactly how long a fully-charged Icom BP-272 Li-ion battery pack would power the IC-705 under intense operation

SSB

SSB at Lake Norman State Park

I was very quickly able to sort out how to record and use the voice memory keying features of the IC-705. There are a total of eight memory positions that can be recorded to the internal microSD card. It’s very simple to use one of the memories in “beacon” mode––simply press and hold one of the memory buttons and the recording is transmitted repeatedly until the user presses the PTT to disengage it. This is incredibly helpful when calling CQ; I typically set mine to play “CQ POTA, CQ POTA, this is K4SWL calling CQ for Parks On The Air.” I’ve also set a five-second gap between playback, allowing for return calls. As I’ve mentioned before, voice-memory keying is incredibly useful and saves one’s voice when calling CQ in the field.

The voice and CW-memory keying features of the IC-705 are robust enough that they could be used in a contest setting to automate workflow. One important note: voice-memory keying saves recordings to the internal MicroSD card. If that card is removed, formatted/erased, or if the file structure is altered, the voice-memory keyer will not recall recordings.

CW

CW at South Mountains State Park

Next, I plugged in my paddles and started calling “CQ POTA” in CW.

As with the voice-memory keyer, CW-memory keying was incredibly easy to set up. Once again, the user once has eight memory positions. As the keyer plays a pre-recording sequence, the IC-705 will display the text being sent.

One of the questions I’m asked most by CW operators about the IC-705 is whether the radio has audible relay clicks during transmit/receive switching. Radios with loud relay clicks can be distracting. My preference these days is to operate in full break-in QSK mode, meaning, there is a transmit/receive change each time I form a character––it allows me space to hear someone break in, but results in much more clicking.

The IC-705 does have relay clicks, but these are very light––equal in volume to those of other Icom transceivers, neither louder nor softer. These clicks, fortunately, are not too distracting to me, and to be fair, I find I don’t even notice them as I operate. With that said, transceivers like my Elecraft KX2 and Mission RGO One use PIN diode switching, which is completely quiet.

Battery Life

Tapping the battery icon will open a larger battery capacity monitor.

My third objective at the first field outing was to test how long the Icom BP-272 Li-ion battery pack would power the IC-705 while calling CQ and working stations in both SSB and CW for an entire activation.

After nearly two hours of constant operation, the BP-272 still had nearly 40% of its capacity.

I didn’t expect this. I assumed it might power the IC-705 for perhaps 90 minutes, max. Fortunately, it seems at 5 watts, one BP-272 could carry you through more than one POTA or SOTA (Summits On The Air) activation. I was pleasantly surprised.

Four months later…

POTA activation at Tuttle Educational State Forest

Since that initial field test, I’ve taken the IC-705 on easily thirty or more individual POTA activations. I’ve also used it at home to chase POTA stations and rag chew with friends.

In short, I’ve found that the IC-705 is a brilliant, robust portable transceiver for SSB and/or CW and a pleasure to operate.

Herein lies the advantage of purchasing a radio from a legacy amateur radio manufacturer: it’s well-vetted right out the door, has no firmware quirks, and is built on iterations of popular radios before it.

I’ve found that IC-705 performance is solid: the receiver has a low noise floor, the audio is well-balanced, the AGC is stable at any setting, and it’s an incredibly sensitive and selective radio.

Digital modes

POTA activation at Lake Jame State Park

One huge advantage of the IC-705 is that it, like the IC-7300, has a built-in sound card for digital modes. This eliminates the need for an external sound card interface. After you’ve read the installation guide, and installed Icom’s USB drivers, simply plug the IC-705 into your computing device via USB cable and you can directly control the ‘705 with popular applications like WSJT-X.

I have not used the IC-705 for digital modes while in the field, but I have done so in the home shack. It was one of the easiest radios I’ve ever set up for FT8 and FT4.

I’m not the biggest digital mode operator, but if you are into it, I expect you’ll be very pleased with the IC-705. It must be one of the most portable, uncomplicated transceivers for digital mode operation currently on the market. I know a number of POTA activators have been using the IC-705 for FT8 and FT4.

D-Star

Being perfectly honest here, I have a chequered history with the D-Star digital voice mode. I purchased an Icom ID-51a and D-Star hotspot several years ago because a local ham pretty much convinced me it was the coolest thing since sliced bread.

And in truth? It is rather amazing.

But at the end of the day I had to admit to myself that I’m an HF guy, and found the user interface and operating procedures just a bit too other-worldly. I kept the ID-51a for perhaps a year, then sold it, along with the hotspot.

Although I knew the IC-705 had D-Star built in, I really hadn’t given it a second thought. But since I’m a reviewer, I simply had to check it out. I still had my D-Star credentials from some years ago, so I set up the IC-705 and connected the transceiver to the Diamond dual band antenna on top of my house.

Fortunately, I was able to hit our only local D-Star repeater and connect on the first go. Note that, like the ID-51a, the IC-705 can use your GPS coordinates, then automatically find the closest D-Star repeater and load the frequency and settings from the default database on the IC-705 MicroSD card.

After reviewing a YouTube video demonstration, I was on the air with D-Star and found the user interface much easier to use than that of the ID-51a. It really helps having a large touch screen.

I’ll admit it: I’m warming back up to D-Star, and I have the IC-705 to thank for that.

Some day, I plan to use D-Star on HF, as well. I acknowledge that it might take some pre-arranging, but perhaps I could even make a D-Star POTA––or better yet, SOTA––contact, if the stars align. It’s certainly worth the experiment.

Let’s talk about broadcast listening

Radio Exterior de España’s interval signal on the IC-705’s waterfall display

Although I’m a pretty active ham radio operator, I’m an SWL and broadcast listener at heart. One of the appealing things about the IC-705 is its excellent receiver range (0.030-470.000 MHz) and multiple operating modes, as well as its adjustable bandwidth.  Broadcast listeners will be happy to know that the AM bandwidth on the IC-705 can be widened to an impressive 10 kHz, which is certainly a stand-out among general coverage transceivers.

After turning on the IC-705 for the very first time, I tuned to the 31-meter band and cruised the dial. I felt like I was using a tabletop receiver: for such a small transceiver, the encoder is on the large side, and the controls are ergonomically designed. The spectrum display and waterfall are amazingly useful.

The front-facing speaker on the IC-705 is well-designed for audio clarity on the ham radio bands. It’s not a high-fidelity speaker, but it’s adequate and has enough “punch” to perform well in the field. Speakers on portable QRP radios are typically an afterthought and are terribly compromised due to space constraints within the chassis. The IC-705’s speaker design feels more deliberate, akin to what you might find on a mobile VHF/UHF rig. Broadcast listeners, in other words, will certainly want to hook the IC-705 up to an external speaker––or, better yet, use headphones––for weak-signal work.

While the received audio isn’t on par with a receiver like the Drake R8B, it’s pretty darn good for a portable general coverage transceiver. The audio is what I would call “flat,” but you are able to adjust the received audio in EQ settings to adjust them to your taste. Audio is well-tailored for the human voice, so I’ve found weak signal IDs are actually easy to grab on the air.

Audio samples

One of the brilliant things about the IC-705 is the fact that it has a built-in digital recorder. Both transmitted and received audio can be recorded in real time and saved to a removable MicroSD card. I made audio recordings of two broadcast stations on the 31-meter band as samples: the Voice of Greece (9420 kHz) and Radio Exterior de España (9690 kHz). The Voice of Greece was moderately strong when I made the recording and Radio Exterior was quite strong. Click on the links to download the .mp3 files for each recording:

Voice of Greece

Radio Exterior de España

I’ve also used the built-in digital recorder to record long sessions of my favorite shortwave, AM, and FM stations. Even with the recorder on, I can typically achieve hours of listening on one battery charge and need no other power supply.

In short? The IC-705 makes for an excellent portable shortwave, mediumwave, and FM broadcast band-recording receiver.

Charging ahead…

The supplied BP-272 battery pack snaps snugly on the back of the IC-705

Power supply is always a concern when taking a transceiver on travels. Most transceivers need a 12-13.8 volt external supply, or an external battery, one that will eventually need to be charged.

This is not the case with the IC-705, because while it can be charged or powered via a 12-13.8V source, it can also be charged via a common 5V USB power supply. Simply insert any USB phone-charging cable into the MicroUSB port on the side of the IC-705, and it will charge the fully-depleted attached BP-272 battery pack in just over four hours.

Indeed, I traveled to visit family one week, and had plotted two park activations both en route and on the way back home. After my first activation, I quickly realized I forgot the supplied IC-705 power cord that I’d normally use to hook the IC-705 up to one of my LiFePo batteries. I was quite disappointed, expecting that I’d missed this opportunity.  Then I remembered USB charging: I simply plugged the IC-705 up to my father’s phone charger, and in four hours, the battery was completely recharged.

To my knowledge, there are no other transceivers that have this capability without modification. A major plus for those of us who love to travel lightly!

Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Here’s the list I formed over the time I’ve spent evaluating the Icom IC-705.

Pros:

  • Frequency range
    • TX: 160 – 6 meters, 2M, 70cm
    • RX: 0.030-470.000 MHz
  • Modes include SSB, CW, AM, FM, DV, RTTY
  • 4.3 inch color touchscreen that’s (surprisingly) readable in full sunlight
  • Multiple means to power/charge:
    • Icom BP-272 battery pack (supplied) for 5 watts output
      • Can be charged via 12V power supply or
      • 5V USB phone charger with standard MicroUSB plug (admittedly, I wish they would have adopted now standard USB-C rather than MicroUSB)
    • External battery for 10 watts of output
  • Top-shelf receiver performance (see Rob Sherwood’s assessment)
  • Wireless LAN connectivity that even allows for native remote control (not tested)
  • Built-in Bluetooth
  • Built-in GPS
  • Built-in Digital Recording
  • Full D-Star functionality
  • RTTY can be sent (using macros) and received/decoded natively
  • Multiple standard connection points on base for mounting (see con)
  • Supplied speaker mic is compact and has programmable buttons
  • Frequency stability is less than ± 0.5 ppm (–10°C to +60°C; 14°F to 140°F)
  • The IC-705 ships with an abridged owner’s manual; I recommend downloading the full version via Icom

Cons:

  • No internal ATU option
  • No built-in tilt stand (see pro)
  • Some minor ergonomic issues:
    • Angled speaker/mic connectors can be challenging to insert as they are too close to the recessed area behind front face, especially for those with larger fingers and/or if in chilly conditions in the field
    • MicroSD card also difficult to access––I use needle-nose pliers to remove and insert

Conclusion

POTA activation of Second Creek Game Land

I purchased the Icom IC-705 with the idea that I would review it and then sell it shortly thereafter. Much to the dismay of my (rather limited) radio funds, I find that I now want to keep the IC-705…indefinitely.

I didn’t think the IC-705 would fit into my QRP field radio “arsenal” very well because I tend to gravitate toward more compact radios that I can easily operate on a clipboard on my lap when necessary. My Elecraft KX2 (TSM November 2016), Elecraft KX1, LnR Precision LD-11 (TSM October 2016), and Mountain Topper MTR-3B probably best represent my field radio interests.

But I’m loving the versatility and overall performance of the IC-705. It’s providing an opportunity to do much more than most of my QRP radios allow.

Here are just a few of the things I’ve done with the IC-705 thus far:

  • Activated numerous parks in SSB and CW
  • Connected to a local D-Star repeater and talked with a fellow ‘705 owner in the UK
  • Listened to ATC traffic (and recorded it)
  • Listened to NOAA weather radio
  • Listened to and recorded local FM stations
  • Enjoyed proper FM DXing
  • Recorded GPS coordinates during a POTA/WWFF activation
  • Made numerous digital mode contacts by connecting the IC-705 directly to my Windows tablet
  • Made a 2-meter SSB contact

Indeed, there are more features on this transceiver than I can fully cover in one review; truly, I consider that a very good thing.

So if you’re looking for a portable transceiver that can truly take you on a deep dive into the world of QRP HF, VHF, UHF, and even satisfy the SWL in you, look no further than the Icom IC-705.

Well played, Icom.

Mark finds an affordable IP67 rated protective case for the Yaesu FT-891

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

Thomas,

I got a new FT-891 recently and wanted a protective case for taking it out into the field.

A mixture of internet searches and Amazon algorithms turned up this very affordable case which closely matches the size of the radio, as the enclosed photograph shows.

It uses the familiar pick and pluck foam, although in two layers.

The base layer is a bit thin, so I might put a layer of rigid plastic over it to stop the feet of the radio pushing down to the outer case.

I prioritised the side wall thickness opposite from the carry handle, as the case is designed to sit on its side like a briefcase.

Via Amazon UK (£20.99)

Mark

Wow, Mark! I do love the size of this case and the fact that it fits the FT-891 so perfectly.

Recently, I’ve been thinking about building out a case to hold one of my smaller QRP transceivers (the KX1, KX2, or MTR3B) in the field to be used when it’s raining. Perhaps this has been on my mind because I’ve been enjoying nearly 5 straight days of rain and fog! A case like this would be an affordable solution and I wouldn’t feel terribly bad about drilling through the case to mount antenna, key, mic, and headphone ports.

I, for one, would love your thoughts about the Yaesu FT-891 as well. I’ve contemplated reviewing it this year mainly because so many field operators rave about it. I’d be curious what you think about it in terms of shortwave radio listening.

Thank you again for the tip!

Looking back at 2020: What radios were in heavy rotation at your home and in the field–?

This morning, I’m looking at the calendar and I see and end in sight for 2020. I think most of us can agree that 2020 will be one for the history books, in large part due to the Covid-19 global pandemic which has had a pretty dramatic affect on many of our lives. It certainly brough my planned travels to a halt. I think many of us are quite happy to show 2020 the door!

As each year comes to a conclusion, I often look back at my radio activities during that year and see how it played out. I especially note the radios I used most heavily throughout the year.

Since I evaluate and test radios, models that are new to the market obviously get a lot of air time. Still, I’m also known to pull radios from the closet and give them some serous air time.

I’m very curious what radios you gave the most air time in 2020?

Here’s my list based on type/application:

Portable shortwave receivers

Since they’re new to the market, both the Tecsun PL-990 (above) and Belka DX (below) got a lot of air time.

I do like both radios and even took the pair on vacation recently even though packing space was very limited. I see the Belka DX getting much more air time in the future because 1.) it’s a performer (golly–just check out 13dka’s review of the Belka DSP) and 2.) it’s incredibly compact. The Belka now lives in my EDC bag, so is with me for impromptu listening and DXing sessions.

A classic solid-state portable that also got a lot of air time this year was the Panasonic RF-B65. Not only is it a performer, but it has a “cool” factor that’s hard to describe. I love it.

Tabletop portables

In a sense, the C.Crane CCradio3 got more play time than any of my radios.  It sits in a corner of our living area where we tune to FM, AM and weather radio–90% of the time, though, it’s either in AUX mode playing audio piped from my SiriusXM receiver, or in Bluetooth mode playing from one of our phones, tables, or computers. In October, the prototype CCRadio Solar took over SiriusXM duty brilliantly. I’m guessing the CCRadio3 has easily logged 1,600 hours of play time this year.

Of course, the Panasonic RF-2200 is one of my all-time favorite vintage solid-state portables, so it got a significant amount of field time.

Software Defined Radios

While at home the WinRadio Excalibur still gets a large portion of my SDR time, both the AirSpy HF+ Discovery and SDRplay RSP DX dominated this space in 2020.

The HF+ Discovery was my choice receiver for portable SDR DXing and the RSPdx when I wanted make wide bandwidth recordings and venture above VHF frequencies.

Home transceivers

Without a doubt the new Mission RGO One 50 watt HF transceiver got the most air time at home and a great deal of field time as well. It’s such a pleasure to use and is a proper performer to boot!

My new-to-me Icom IC-756 Pro, however, has become my always-connected, always-ready-to-pounce home 100W HF transceiver. It now lives above my computer monitor, so within easy reach. Although it’s capable of 100+ watts out, I rarely take it above 10 watts. The 756 Pro has helped me log hundreds of POTA parks and with it, I snagged a “Clean Sweep” and both bonus stations during the annual 13 Colonies event.

Field transceivers

The new Icom IC-705 has become one of my favorite portable transceivers. Not only is it the most full-featured transceiver I’ve ever owned, but it’s also a brillant SWLing broadcast receiver. With built-in audio recording, it’s a fabulous field radio.

Still, the Elecraft KX2 remains my choice field radio for its portability, versatility and incredibly compact size. This year, in particular, I’ve had a blast pairing the KX2 with the super-portable Elecraft AX1 antenna for quick field activations. I’ve posted a few field reports on QRPer.com and also a real-time video of an impromptu POTA activation with this combo:

How about you?

What radios did use use the most this year and why? Did you purchase a new radio this year? Have you ventured into the closet, dusted off a vintage radio and put it on the air?

Dockside DXing with the super-portable Belka-DX receiver

I’ve been on the coast of South Carolina enjoying a little R&R with my wonderful family.

We rented a vacation home on a tidal river just south of Charleston, SC and it was just what the doctor ordered. The location was gorgeous, the weather was amazing, and there was very little RF interference outside our home.

The best part? We had full access to a private dock.

I took a few portable radios on vacation (ahem…obviously!) but I so thoroughly enjoyed my time with the Belka-DX.

If you haven’t gathered already, I really appreciate simple radios for field operation and it doesn’t get much more simple than the Belka-DX or Belka-DSP.

The radio is so incredibly compact, durable, and a pleasure to operate–especially if cruising the broadcast bands.

On the dock, I didn’t have a place to easily hang a wire antenna, so I used the supplied telescoping whip antenna. It served me well on a number of listening sessions.

As 13dka pointed out in his brilliant review of the Belka-DSP, the Belka radios are so compact, yet pack so much performance, they smack of a little spy radio! On top of that, the chassis is incredibly durable. I can’t tell you how much I love this. My Belka receiver has been living in my EDC bag in a small zippered pouch.

I barely notice it in my bag–it take up almost no space and weighs so little–but in the back of my mind I know I have a portable DXing machine everywhere I go.

I have no fear of being damaged in my bag, either–the chassis protects it so well.

Since London Shortwave has sorted out how to make spectrum recordings using the Belka-DX I/Q out, you’d better believe I’ll be sampling spectrum as I travel the globe post-pandemic!

I didn’t have time to gather what I needed for making Belka-DX spectrum recordings on this trip, but you can be certain I will when I return!

I should add that one of the little joys about my dockside DXing spot this past week was watching dolphins swim by as I tuned to some of my favorite broadcasters. Bliss.

A comprehensive review of the Mission RGO One general coverage 50 watt transceiver

The following review was first published in the November 2020 issue of The Spectrum Monitor magazine:


A review of the Mission RGO One ham radio transceiver

by Thomas (K4SWL / M0CYI)

Wow…I love this!

If I am perfectly frank, that would sum up my initial impression of the Mission RGO One.

It was the 2018 Hamvention in Dayton, Ohio, and I had just met up with radio engineer Boris Sapundzhiev (LZ2JR) who was debuting the prototype of his 50-watt transceiver kit, the Mission RGO One. With its clean, functional design and simple front face, large weighted encoder, and enough tactile buttons and multi-function knobs to keep one’s most needed features within reach, the kit was certainly pushing all the right buttons for me.  Without a doubt, I was impressed from the start.

Boris (LZ2JR) the designer and engineer of the Mission RGO One.

To my mind, the RGO One smacks of classic 1990s-era transceivers:  a traditional tabletop front-facing panel, a large fold-out bail, and a unfussy backlit LCD display that’s large enough to read in the field and viewable at any angle.

Perhaps it’s only because I can’t turn off the innate radio reviewer, that I was rapidly checking mental boxes in this first encounter with the RGO One.  Indeed, when I first set eyes on any new radio, I do skim through my mental “operations checklist” to see how difficult the rig might be to use at home and/or in the field. Specifically, I’m looking for the following controls:

  • Encoder
  • AF Gain
  • RF Gain
  • Mode switch
  • Power output adjustment
  • Tune/Xmit button
  • Preamp/Attenuator
  • VFO A/B
  • Split and A=B
  • Mic gain and keyer speed
  • RIT
  • Filters
  • Band switching and direct frequency entry
  • Key and encoder lock

Of course, these days it’s fairly rare that radios actually contain all of these functions without the user having to dig into layers of menus, multi-function controls, or touch-screen options to access them.

Remarkably enough, the Mission RGO One, despite simple design, manages to include all of these features on the front panel without the need of embedded menus. In contrast with some of the radios I’ve tested and evaluated over the past several years, I could tell by the layout alone that the Mission RGO One was developed by an active ham radio operator and DXer: the controls are that intuitive.

Alas, the tantalizing prototype on Boris’ table in the 2018 Hamvention flea market was for show only.

Boris promised that he’d have fully-functional models available at the 2019 Hamvention. Because of this, following that first meeting in 2018, I kept in touch with Boris; we arranged to meet again at the 2019 Hamvention so I could take a second, much closer look at the RGO One––especially since he intended to start shipping the first very limited, early-production-run rigs shortly afterward.

So…did Boris deliver?  And more importantly: did the RGO deliver––?  Let’s find out.

On The Air

Within hours of taking delivery of the prototype radio, I had it in the field activating parks.

It was May 2019 when Boris delivered on his promise, handing me a loaner prototype RGO One. He did so with the understanding that the prototype was still a little rough around the edges. I acknowledged this, thinking in terms of a late Beta-test model since he welcomed reports of any bugs or anomalies I encountered and was fully prepared to address them.

After taking the initial RGO One to the field, I did note a few bugs, but nothing major.  All of my field notes were then sent to Boris and turned into action items.

Then, in July of 2020, Boris sent me a fully-upgraded Mission RGO One with the new internal ATU and optional adjustable filter. This radio represented the “fully-grown” production model, and in preparation to put it through its paces, I returned the prototype.

Although there are planned hardware upgrade options and, of course, firmware upgrades, the RGO One has now reached full maturity as a transceiver.

However, it was one thing to have ham-friendly ergonomic controls. The real question was, how did the RGO One stack up against the competition? It was time to find out.  After all, this is the danger of a “love at first sight” radio encounter––it often leaves the door open for disappointment, and of this I was well aware.

What follows is my full review of this 2020 Mission RGO One transceiver. Let’s take a deep dive into this rig…

Features and specifications

 

What follows are some of the RGO One features and highlights as written in the product manual (PDF):

  • QRP/QRO output 5 – 50W [can actually be lowered to 0 watts out in 1 watt increments]
  • All-mode shortwave operation – coverage of all HAM HF bands (160m/60m optional)
  • High dynamic range receiver design, including high IP3 monolithic linear amplifiers in the front end, and diode ring RX mixer or H-mode first mixer (option)
  • Low-phase noise first LO – SI570 XO/VCXO chip
  • Full/semi (delay) QSK on CW; PTT/VOX operation on SSB. Strict RX/TX sequencing scheme with no “click” sounds
  • Down conversion superhet topology with popular 9MHz IF
  • Custom-made crystal filters for SSB and CW and variable crystal 4 pole filter – Johnson type 200…2000Hz
  • Fast-acting AGC (fast and slow) with 134kHz dedicated IF
  • Compact and lightweight body, only 5 lbs
  • Custom-made multicolor backlit FSTN LCD
  • Custom-molded front panel with ergonomic controls
  • Silent operation with no clicking relays inside – solid state GaAs PHEMT SPDT switches on RX (BPF and TX to RX switching) and ultrafast rectifying diodes (LPF)
  • Modular construction – Main board serves as a “chassis” also fits all the external connectors, daughter boards, plus inter-connections, and acts as a cable harness
  • Optional modules – Noise Blanker (NB), Audio Filter (AF), ATU, XVRTER, PC control via CAT protocol; USB UART – FTDI chipset
  • Double CPU circuitry control for front panel and main board – both field programmable via USB interface
  • Memory morse code keyer (Curtis A, CMOS B); 4 Memory locations 128 bytes each

Build quality

First impressions proved accurate in terms of construction.  I’m very pleased with the build quality of the Mission RGO One. Keep in mind, however, you might note from the photos that some items––like the volume and multifunction knobs––are 3D printed, and I’m not certain if they’ll ever have custom knobs manufactured.  But I really don’t even think this is necessary, as the 3D printed ones are very nice, indeed––moreover, should a replacement ever be needed, I love the idea I could simply print one myself!

The RGO One main optical encoder/tuning knob is just brilliant. It’s weighted properly for the right amount of “heft” while tuning. I’m very pleased with the overall feeling and quality. It’s substantial, yet silky-smooth in operation, just what I look for in a tuning knob.

On the back of the unit, there is an externally-mounted heat sink with two small fans. These fans are quiet and efficient.

The chassis and bail are both top-shelf quality and should withstand years of field use. Just do keep in mind that like almost every other amateur transceiver currently on the market (save the recently reviewed lab599 Discovery TX-500), the chassis is neither water-proof nor weather-proof, so will require common-sense care to protect it from the elements.

Portability

The Mission RGO is relatively compact, lightweight (only 5 lbs without the ATU), and has a power output of up to 55 watts, even though the specs list just 50 watts. As a point of comparison, most other rigs in this class have a maximum output of 10 to 20 watts, and require an external amplifier for anything higher. The form factor is very similar to the Elecraft K2.

The light weight of the rig and the extra power makes the RGO One a capable and versatile field radio. Although the RGO One is configured like a desktop radio (with a front-facing panel), it’s still relatively compact and can easily be set up on a portable table, chair, or on the ground. Unlike field-portable rigs with top-mounted controls (think the Elecraft KX3 or KX2), obviously, it would be tough to do handheld or laptop operation.

The RGO One should also play for a long time on battery power as the receive current drain is a respectable 0.65A with the receiver preamp on. It’s not as efficient as, say, an Elecraft KX3 or the new Icom IC-705, but keep in mind the RGO One can provide 50 watts of output power and has a proper, internally-mounted, amplified speaker. The popular 100 watt Yaesu FT-891, in comparison, has a current drain closer to 1.75 to 2.0 amps [update: actually the specifications indicate 2 Amps in receive, but user reports are less than half that amount].  I pair the RGO One with my larger 15 aH Bioenno LiFePo battery. When fully-charged, I can operate actively for hours upon hours without needing to recharge.

Mission RGO One Bioenno LiFePo

The Bioenno 15aH battery powers the Mission RGO One for hours at a time in the field.

If it’s any indication of how much I wanted to take this rig to the field, when Boris handed me the prototype RGO One on Saturday at the 2019 Hamvention, I had it on the air that same day doing a Parks On The Air activation at an Ohio State Park.

Since then, I’ve easily taken the Mission RGO One on 30 or more park activations.

Performance

What’s most striking and obvious about the Mission RGO One’s receiver from the moment you turn it on is the low noise floor. It’s incredibly quiet. So much so that more than once, I’ve double checked to make sure RF gain hadn’t been accidentally altered as I started a field activation. I’d call CQ a few times, though, and when stations return they literally pop out of the ether. The RGO One currently has no digital noise reduction (DNR) but frankly, I don’t miss it like I might in other transceivers. Indeed, the RGO One is a radio I’ve reached for when the bands are noisy because the AGC and receiver seem to handle rough atmospheric conditions very well.

The RGO One’s built-in, top-mounted speaker provides ample audio levels for the shack, but in a noisy field environment, I wish it had a little more amplification. I’ve also used my Heil Pro headset and even inexpensive in-ear earphones connected to the front panel headphones jack in the field. The audio via headphones is excellent.

Let’s take a look at how well the RGO One performs by mode:

CW

First and foremost, CW operators will appreciate the RGO One’s silky-smooth full break-in QSK. The  RGO One employs clickless and quiet pin diode switching–a design feature I’ve become particularly fond of as traditional T/R relays can be noisy and distracting when not using headphones.

The RGO One also has a full compliment of adjustments for the CW operator including adjustable delay (default is 100ms), iambic mode, weight ratio, hand key/paddle, adjustable pitch, and sidetone volume.

The key jack is a standard three conductor 1/8” jack found on most modern transceivers. It’s located on the back of the radio.

My review unit has the optional variable width narrow filter which I highly recommend if operating in crowded conditions. I’ve used the RGO One on ARRL Field Day and found that it easily coped with crowded band conditions. Even after a few hours on the air, I had very little listener fatigue.

I also find that, as I mentioned earlier, CW signals just seem to “pop” out of the ether due to the low noise floor and excellent sensitivity/selectivity.

The RGO one also sports four CW keying memories where you can record your CQ, callsign, or even contest exchange. I’ve become incredibly reliant on memory keying to help facilitate my workflow in the field—while the radio is automatically sending my CQ or my regards and callsign to an station I’ve just worked, my hands are free to log the contact, adjust the radio, or even eat lunch!

Memory keying does require one long-press of the “6” button followed by either the “1,” “2,” “3,” or “4” button to play a message. Occasionally I won’t hold the 6 button long enough and accidentally move my frequency down one meter band since the 6 button is also the band “down” button. While it doesn’t happen often, it’s frustrating when it does but I think it could easily be fixed in the firmware as it’s really a timing issue.

SSB

Likewise, phone operators will be very pleased with the Mission RGO One. During all of my testing, I’ve only used the microphone supplied with the radio mainly because I don’t currently own another radio with an RJ-45 type microphone connector.

I do love the fact the microphone port is on the front panel of the radio—it’s very easy to connect and disconnect (in contract to the recently released Icom IC-705, for example). I’ve gotten excellent audio reports with the RGO One in SSB mode and have even monitored my own tests and QSOs via the KiwiSDR network.

Compression, gain, and VOX controls are easily accessible. One missing feature at present is a voice memory keyer. For field operators activating sites for the POTA, WWFF, or SOTA program, voice memory keying is huge as it saves your voice from calling “CQ” over the course of a few hours. I understand Boris does plan to implement voice memory keying in a future speech processor board.

AM Mode

Since the RGO One has general coverage receive and since I’m a shortwave broadcast listener, I was disappointed to find that there is presently no AM mode. Boris told me he does plan to add AM mode, “to be implemented in future versions of the IF/AF board only on RX.”

With that said, I can always zero-beat a broadcaster and use a wide SSB filter to listen to broadcasts which is more than I could do, for example, with my (ham band only) Elecraft K2.

At the end of the day, the RGO One is a high-performance, purpose-built ham radio transceiver, so the current lack of AM mode isn’t a deal-breaker for me, but I would love a wide AM filter on this rig.

ATU

The 2020 review model I received has the internal automatic antenna tuner which I feel is a worthy upgrade/addition. In the field, I’ve paired the RGO One with my Chameleon CHA Emcomm III Portable random wire antenna which requires an ATU in order to find matches across the bands. The pairing has been a very successful one because the Emcomm III can handle up to 50 watts power output in CW and covers the entire HF band when emptying the RGO One ATU.

 

Even though it’s a minor thing, I also like the fact that the RGO One ATU operates so quietly, even though with the present firmware it takes longer than some of my other ATUs to find a match.

Power

One thing I’ve found very useful in the field and, no doubt others will as well is the power output. In many ways, the RGO feels like a larger QRP radio (think Ten-Tec Argonaut V or VI) but it’s actually able to pump out 55 watts (often five watts more than specified). In single sideband mode, this is a meaningful amount of power output compared to, say, 5 or 10 watts. When I activate a rare park, or an ATNO (All Time New One), I’ve been taking the RGO One more times than not in order to get the best signal possible and maximum amount of contacts. Running full power, the rig never feels warm—heat dissipation is superb—and the fans on the back of the heat sink are super quiet.

I actually feel like the 50 watts of output power gives the RGO One a market niche since it sports top-shelf performance as you might expect in the venerable Elecraft K2, for example, but  not being a 10 watt or 100 watt radio, rather something in between which saves a little weight and also the need for heftier heat dissipation.

Other unique features

The RGO One has some interesting features not found in similar radios.

For one, there are no less than ten color options for the custom backlit LCD display, along with adjustable contrast and backlighting intensity.

The RGO One team also documents how to access hidden admin menus for granular adjustments to transceiver parameters, but of course you’d want to adjust those with caution and note values prior to changing them. When you receive your RGO One, Boris includes a sheet with all default values to make stepping back much easier.

Hands-on philosophy

At the end of the day, the Mission RGO One is a kit that can eventually be purchased in kit form, or as a fully assembled transceiver. It’s modular: you can add and upgrade features as you wish. Some field operators, for example, may wish to omit the ATU to save a little extra weight or cost. I actually love this philosophy and I think it’s one that’s made Elecraft such a successful manufacturer.

The process of upgrading firmware is slightly more involved than you might find with, say, an Elecraft, Icom, or Yaesu product. It’s a two stage process where one upgrades both the front panel and the main board separately. I completed a firmware update only a few weeks prior to publication. It took me perhaps 15 minutes with my PC as I followed Boris’ step-by-step instructions (http://lz2jr.com/blog/index.php/rgo-one-firmware-update-procedure/).

There is also an active email discussion group for the Mission RGO One (https://groups.io/g/RGO-ONE/) where participants share experiences, modifications, and even any glitches or bugs that are discovered. This group is closely monitored by the RGO One team, so items are addressed very quickly. I highly recommend joining this discussion group if you see an RGO One in your future.

Also, I’ve gotten great customer support from Boris (LZ2JR) and have heard the same from group members. He’s very much open to critical customer feedback.

Summary

Mission RGO One POTA

Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget some of my initial impressions. Here is the list I formed over the time I’ve spent evaluating the 2020 production model Mission RGO One.

Pros:

  • Excellent sensitivity and selectivity
  • Very low noise floor
  • Excellent, clean audio (see con)
  • Silky-smooth QSK
  • Full compliment of CW and SSB features and adjustments
  • CW memory keyer
  • Superb ergonomics with no need to access embedded menus for common features
  • 50 watts output power with effective quiet heat dissipation
  • Lighter weight compared with comparable transceivers
  • Direct frequency entry
  • Standard Anderson Powerpole power port on rear panel

Cons:

  • No voice keyer memory (at time of posting, but is planned in upgrade)
  • No notch or auto notch filter (at time of posting, but is planned)
  • No 6 meter option
  • No AM mode (at time of posting, but is planned)
  • Firmware updates are a two stage process
  • Would like slightly more audio amplification while using internal speaker in noisy outdoor environments

Conclusion

If you can’t tell, I’m impressed with the Mission RGO One because it does exactly what it sets out to do.  The RGO One is designed for an operator who appreciates rock-solid performance with simple, intuitive ergonomics.

While teaching an amateur radio course to our homeschool cooperative high school students last year, I picked the RGO One as the best field radio for HF demonstrations.

I’ll never forget setting the (prototype) RGO One for the first time on a folding table outside the classroom under a large tree. I had the students erect both an end-fed resonant antenna and a simple 20 meter vertical. I picked the RGO one because all of the adjustments we had talked about in the classroom—AGC, Filters, A/B VFOs, Direct Frequency Entry, Pre Amp, Attenuation—are on the front panel and one button press away.

We hopped on the air with one of my students calling CQ single sideband on the 20 meter band.  Her very first contact was with a station in Slovenia—and she simply beamed with excitement. All of my female students that term passed their Technician exam by the end of the term.

The RGO One is a very inviting radio.

I’ve had the luxury of testing, evaluating, and working with everything from one of the first prototypes to the latest updated version of the RGO One. It’s rare that I’m able to evaluate a radio over such a long period of time.

Even with the very early, bare-bones prototype, I was impressed with this transceiver’s performance characteristics. I’m not the only one either. It’s almost become routine new discussion group members join prior to receiving their radio, then announces how blown away they are with its performance. Check out eHam reviews, too—at time of posting, it’s a solid five stars at time of posting.

The RGO One reminds me of simple, classic radios of the 1980s and 90s, but underneath, it’s packing state-of-the-art performance.

Is it perfect? No radio is perfect, but I must say that for what it offers, it really hits the sweet spot for this radio operator.  It’s a joy to use.

There are still features in the works that will either be implemented with future firmware updates, or with future boards. In terms of performance and appearance, it reminds me of the Ten-Tec Eagle and Elecraft K2—both benchmark rigs in my world. And like the Eagle and K2, the RGO One is happy in the field, at home, or even on a DXpedition. It’s a simple radio that beckons to be on the air.

A little QRP radio magic this weekend

SWLing Post readers: I originally posted the following article on QRPer.com where I publish most of my ham radio field reports. It was the first full Parks On The Air activation with my recently re-acquired Elecraft KX1 transceiver and it was very memorable. I hope you enjoy:

Yesterday [Saturday, November 14, 2020] my family decided to make an impromptu trip to one of our favorite spots on the Blue Ridge Parkway at Richland Balsam–the highest point on the BRP.

Of course, it was a good opportunity to fit in a Parks On The Air (POTA) activation, but I had also hoped to activate Richland Balsam for Summits On The Air (SOTA) simultaneously.

It being well beyond leaf-looking season, we had hoped the BRP would be relatively quiet, but we were wrong.

Trail heads were absolutely jam-packed and overflowing with visitors and hikers. We’ve noticed a sharp hiker uptick this year in western North Carolina due in no small part to the Covid-19 pandemic. People see hiking as a safe “social-distance” activity outdoors, but ironically, hiker density on our single-track trails is just through the roof.   One spends the bulk of a hike negotiating others on the trail.

The trail head to Richland Balsam was no exception. Typically, this time of year, we’d be the only people parked at the trail head but yesterday it was nearly parked full.

Being natives of western North Carolina, we know numerous side-trails and old logging/service roads along the parkway, so we picked one of our favorites very close to Richland Balsam.

We hiked to the summit of a nearby ridge line and I set up my POTA station with the “assistance” of Hazel who always seems to know how to get entangled in my antenna wires.

“I’m a helper dog!”

Taking a break from using the Icom IC-705, I brought my recently reacquired  KX1 field radio kit.

Gear:

I carried a minimal amount of gear on this outing knowing that there would be hiking involved. Everything easily fit in my GoRuck Bullet Ruck backpack (including the large arborist throw line) with room to spare.

I took a bit of a risk on this activation: I put faith in the wire antenna lengths supplied with my new-to-me Elecraft KX1 travel kit. I did not cut these wires myself, rather, they are the lengths a previous owner cut, wound, and labeled for the kit.

With my previous KX1, I knew the ATU was pretty darn good at finding matches for 40, 30, and 20 meters on short lengths of wire, so I threw caution to the wind and didn’t pack an additional antenna option (although I could have hiked back to the car where I had the CHA MPAS Lite–but that would have cut too much time from the activation).

I didn’t use internal batteries in the KX1, rather, I opted for my Bioenno 6 aH LiFePo battery which could have easily powered the KX1 the entire day.

I deployed the antenna wire in a nearby (rather short) tree, laid the counterpoise on the ground, then tried tuning up on the 40 meter band.

No dice.

The ATU was able to achieve a 2.7:1 match, but I don’t like pushing QRP radios above a 2:1 match if I don’t have to. I felt the radiator wire was pretty short (although I’ve yet to measure it), so clipping it would only make it less resonant on 40 meters.

Instead, I moved up to the 20 meter band where I easily obtained a 1:1 match.

I started calling CQ POTA and within a couple of minutes snagged two stations–then things went quiet.

Since I was a bit pressed for time, I moved to the 30 meter band where, once again, I got a 1:1 match.

I quickly logged one more station (trusty N3XLS!) then nothing for 10 minutes.

Those minutes felt like an eternity since I really wanted to make this a quick activation. I knew, too, that propagation was fickle; my buddy Mike told me the Bz numbers had gone below negative two only an hour before the activation. I felt like being stuck on the higher bands would not be to my advantage.

Still, I moved back up to 20 meters and try calling again.

Then some radio magic happened…

Somehow, a propagation path to the north west opened up and the first op to answer my call was VE6CCA in Alberta. That was surprising! Then I worked K3KYR in New York immediately after.

It was the next operator’s call that almost made me fall off my rock: NL7V in North Pole, Alaska.

In all of my years doing QRP field activations, I’ve never had the fortune of putting a station from Alaska in the logs. Alaska is a tough catch on the best of days here in North Carolina–it’s much easier for me to work stations further away in Europe than in AK.

Of all days, I would have never anticipated it happening during this particular activation as I was using the most simple, cheap antenna possible: two thin random lengths of (likely discarded) wire.

People ask why I love radio? “Exhibit A”, friends!

After working NL7V I had a nice bunch of POTA hunters call me. I logged them as quickly as I could.

I eventually moved back to 30 meters to see if I could collect a couple more stations and easily added five more. I made one final CQ POTA call and when there was no answer, I quickly sent QRT de K4SWL and turned off the radio.

Here’s a map of my contacts from QSOmap.org:

I still can’t believe my three watts and a wire yielded a contact approximately 3,300 miles (5311 km) away as the crow flies.

This is what I love about field radio (and radio in general): although you do what you can to maximize the performance of your radio and your antenna, sometimes propagation gives you a boost when you least expect it. It’s this sense of wireless adventure and wonder that keeps me hooked!

My Obsession with Muji A6 Mini Logging Notebooks

In many ways, I’m old school. While I love leveraging technology to make the most of my radio world, I also have a sincere appreciation for simple “analog world” solutions to my needs.

I’m a notepad guy.

When I moved to France to do undergraduate studies in the early 90s, I became reliant on small notepads to keep my brain organized and maintain some sense of sanity. I kept one in my pocket, my backpack, and had larger notepads for each one of my classes. It was in France I discovered the amazingly wide variety of notepads that could be found in a Papeterie or stationery store. While I could hardly afford notepads and pens/pencils I found in those stores, I did occasionally splurge.

To this day, I keep notepads in my EDC bag and near my radio desk. I find that the act of writing something down–pen to paper–locks thoughts/memos in my memory much better than taking notes on a digital device.

Paper Logging

If you’ve followed any of my field reports for Parks On The Air (POTA) here on the SWLing Post  or on QRPer.com, you’ve probably seen me employ a wide variety of note pads and logging sheets.

While I often do live logging with my Microsoft Surface Go tablet to speed up log submissions, I always log on paper first. Always.

For one thing, when I’m copying a callsign in Morse Code (CW), I prefer writing down the call as it’s being sent. Regardless if a contact is in CW or phone, I copy the callsign and exchange information on paper first, then immediately transfer it to my logging software on the tablet. I carry the Surface Go tablet with me on about 75% of my field activations, but leave it at home if I’m doing a substantial amount of hiking.

Not only do I find it easier to log on paper first, but by having a full set of logs in notebooks, I know I’ve got a proper archive of the activation if my tablet fails me.

Plus–if I’m being completely honest here–I love seeing my handwritten logs after an activation. It gives me more of a sense of accomplishment for some reason. Don’t ask me why.

Muji A6 Notebooks

A couple months ago, I was searching for a notepad that could easily fit in one of my compact field radio kits.

My wife (an artist) suggested I check out Muji Notepads of Japan because she’s both pleased with the quality and price as compared with other quality notebooks. She measured my field kit pack and suggested the Muji A6 lined notebook. On Amazon, they’re sold in packs of 5 books for $12.00 US. I was skeptical about the size, but placed an order anyway.

Each book has 30 pages which means if I write on the front and back of each sheet, it should last me up to 30 average park activations (assuming roughly 25-40 contacts per activation). Since my activations tend to be short, it’s rare that I exceed 40 contacts.

I purchased a pack of five notebooks and put one notebook in each of my radio field kits. I even dedicate one for my Elecraft AX1 antenna kit.

I love these Muji notepads–they’re compact and thin, but the paper quality is nice and it’s large enough I can use “normal” hand writing. While I tend to prefer spiral-bound notebooks for logging, I like the binding on these notebooks because it doesn’t catch on anything and keeps the profile super thin which is perfect for small packs and cases. The pages lay flat once open, too.

For the record, I also keep a few Rite in the Rain weatherproof notebooks handy if I’m heading to a park or summit after heavy rainfall, if there’s the possibility of rain in the forecast, or if I’m camping. They’re also indispensable. The Muji Noteboooks aren’t designed to handle water, but in truth it’s very rare that I’m playing radio in the rain. I prefer the slim profile of the Muji Notebooks for day-to-day field work.

I just ordered another pack of five this Muji A6 Notebooks this week and plan to put one in my portable SDR kit, and two of my portable receiver kits. In truth, my shortwave radio logs are less organized than my ham radio logs, but I’m constantly jotting down broadcasters, times, frequencies and receiver performance notes.
