Using the Yaesu FT-891 for SWLing

by Mark Hirst

Woodland Operation in North Hampshire

Introduction

While I have a small collection of portable shortwave radios for outdoor listening, I’ve been looking to fill a gap in my amateur radio lineup for a while. Outdoor operation has become important in recent years as solar cycle conditions deteriorated along with rising levels of QRM in urban neighbourhoods. The ICOM IC–7200 with Wellbrook loop stays at home fighting a losing battle with PLA noise, while the very portable FT–817ND does occasional data modes contacts and outdoor listening. Somewhere in the middle, the FT–891 promised to provide a modern and more powerful data modes station, a radio to take on holidays, needing external batteries, but portable enough for walks into the country side. Earlier this year, I bought one new from my local ham radio store, and what follows are my findings and observations so far on shortwave listening.

Audio Characteristics

I’ve accumulated hundreds of recordings of VOA Radiogram and Shortwave Radiogram since 2013, so a recent woodland expedition with the FT–891 was an opportunity to compare a recording made with it against those of other radios I’ve used.

The most striking difference is the lack of frequencies in the lower part of the audio spectrum along with a distinct cut off at around 5kHz.

This is easily visualised in the following comparison between the FT–891 and the Tecsun PL–680. Note the conspicuous pillar associated with MFSK32 from these Shortwave Radiogram broadcasts, and interfering RTTY on the FT–891 recording:

Audio Frequency Analysis

While this audio profile may not be to everyone’s taste, the extra sparkle yields voice audio that is clear and distinct. I find those low frequencies make the audio muddy and tiring to listen over long periods, so I’m quite happy with this.

When listening to speech based broadcasts through the top mounted speaker, the audio is also precise and intelligible, and provides more than enough volume.

You can judge for yourself from this 2 minute video I made recently:

Headphones, External Speakers and Recording

You also have the option of connecting an external speaker or headphones to a socket on the side of the radio. Be aware that the audio level is different for headphones, and is controlled by a small switch hidden behind the front panel. I expect people may go for one option such as headphones and then stick with it, rather than continually detaching the front of the radio and moving the delicate switch back and forth.

If you turn the volume right down you will hear a hiss, although its really only noticeable if you face the speaker directly and get close. Listening outdoors with the sounds of nature around you? It’ll be fine. There’s no way to avoid it with headphones of course, with forums suggesting inline resistors or high impedance headphones as solutions.

Audio recordings can of course be taken from the headphone socket, but you will get better results from the data port on the back. I use a UD04YA cable which provides 3.5mm audio in and audio out jacks, plus a USB cable to provide PTT functionality. It’s meant for data modes operation with the FT–817, but I have used it successfully with the FT–891 for PSK contacts using fldigi, eliminating the need for CAT control through a second cable to the radio’s USB port.

Customising for SWL

The advanced manual for the FT–891 helpfully provides a section called ‘Tools for Comfortable and Effective Reception’, so I began configuring the radio using the guidance there.

First up was re-configuring the front panel RF/Squelch knob to only control RF gain (Menu 05–05). I use the same configuration on my FT–817ND to dial back RF gain, allowing the AGC to pick up the slack.

Next was enabling the awkwardly named Insertion Point Optimisation (IPO) which switches out the pre-amplifier. It’s interesting to note that this setting can be associated with a stored memory channel, which became relevant later when I used CAT control to program some favourite frequencies.

The radio has an attenuator, although I’ve not found a need for it so far.

The AGC can be configured as Auto, Fast, Mid, and Slow. Since it is not a ‘set and forget’ setting like the RF control or IPO options, it might be a good candidate for assigning to one of the three user definable buttons below the LCD screen.

Audio can be fine tuned using four menu options (06–01 to 06–04) to control high and low frequency cutoff, but after some experimentation I have turned these options off.

As an aside, I found the LCD backlight, button illumination and TX/Busy lights too bright for indoor use, so dialed them back to their minimum values.

Listening Tools

The radio provides some additional tools as part of its IF DSP. The features of particular interest are Digital Noise Reduction (DNR), Noise Blanker, IF Notch Filter, Digital Notch Filter, and Narrow IF filter. Contour, IF Bandwidth, and IF Shift are not available in AM mode, and you must resort to SSB to get them. More about SSB in a moment.

Out of this wide array of options, I’ve only explored Digital Noise Reduction and the Narrow IF filter so far, as they offer fairly immediate gains without too much configuration.

Narrow filter simply reduces the total IF bandwidth from 9kHz to 6kHz, which gives some immediate relief to higher frequency noise. In tougher conditions at home tackling QRM, the harsher sound it causes has sometimes been counter productive.

At the outset, it’s obvious that the DNR capability of the FT–891 is a powerful feature. Rather than providing a level of processing that varies from a little to a lot, the radio provides 15 different ‘algorithms’ which can be selected for best results. This means you will tweak the DNR setting to address signals on a case by case basis.

Comparing it with the IF noise reduction of my ICOM IC–7200, the ICOM has a scale of diminishing returns as the DSP level is turned up, whereas the FT–891 seems to start strong and it’s more about picking the algorithm that sounds best.

After testing the DNR on AM broadcast stations away from the noise at home, voice audio sounds distant and words can be clipped, which is fine for SSB amateur radio contacts, but makes me think it’s not a feature of first resort when trying to improve broadcast reception. In those circumstances, the narrow filter might be a better option.

The Trials of Single Side Band

On the matter of SSB and using it to combat adjacent or co-channel signals, the radio offers a single SSB option in the mode menu, picking USB or LSB for you automatically based on the current band. When tackling broadcast band interference however, you want the option to go in either direction. The radio also changes the current frequency by 700Hz when SSB is selected, which then has to be corrected with the main dial.

You would begin by switching to SSB mode by pressing and holding the band button. If you’re lucky, the default setting is the one you want.

If it isn’t, activate the settings menu with a long press of the F key, go to the menu option SSB BFO (11–07), select it and use the multi-function knob to change the mode away from Auto to LSB or USB.

As you are doing this, the VFO will change to LSB or USB too. Leave the setting on the option that suits your needs.

If you exit the menu option without saving (pressing F), the mode will remain changed, but the override is not saved. This can be a useful quirk because next time you turn the radio on, it will be back in auto mode.

If you commit the override by pushing the multi-function knob instead, the radio will stay in manual mode until you remember to return to the menu and restore automatic behaviour again.

It’s a needlessly complicated system, as I discovered recently while recording another Shortwave Radiogram broadcast. Even after testing the procedure previously for this article, the radio was determined to stay in LSB no matter what.

Memory Programming

Since the radio has no keyboard for direct frequency input, an early priority for shortwave listening was to program some of the 99 memories available. My plan was to have some favourite broadcast stations, along with WX, Volmet, GMDSS, and some data mode frequencies. To handle ad-hoc stations however, I wanted a way of moving quickly across the main shortwave bands without excessive use of the main tuning dial or multi-function knob.

Taking the official definitions of the broadcast bands between 60m and 16m, and combining those with frequency schedules, I came up with a series of frequencies 150kHz apart across each of those bands, guaranteeing that no broadcast was more than 150kHz away.

The combined list of favourites and the 150kHz stepping stone frequencies resulted in 70 memory channels in total. As I wanted to apply alphanumeric tags to those channels, and didn’t relish the prospect of entering them manually, my next port of call was the CAT control manual to see how those memories could be set programmatically.

While there is commercial software available for the FT–891, I only needed to set up the memory channels, so decided to adapt some PowerShell I’d written for another radio, sending the necessary serial port commands to configure my list.

Now that is done, I can fast travel using the stepping stone memories to the closest point in a band, then use the fast mode of the main tuning dial to move quickly to my final destination.

The following table lists my current stepping stone channels in kHz:

60m 49m 41m 31m 25m 22m 19m 16m
4750 5900 7200 9400 11600 13570 15100 17480
4900 6050 7350 9550 11750 13720 15250 17630
5050 6200 7500 9700 11900 13870 15400 17780
7650 9850 12050 15550 17930
7800 15700

Memory Access

An obvious way to access the memories is to toggle memory channel mode with the V/M button, then cycle through the memories using the multi-function knob. Depending on your memory choices, you will hear relays clicking as the radio jumps back and forth between widely spaced frequencies and bands. You will also need a good memory of your memories, so you know which way to turn the multi-function knob.

An alternative and perhaps faster method is to press the M>V button. This brings up a multi-line listing of memories that can be scrolled through using the multi-function knob. Pressing the M>V button again copies the selected memory to the VFO and leaves you in VFO mode. This avoids the radio flipping across bands and the associated relay activity.

Although it is not documented, if you push the multi-function knob on a selected memory channel in the multi-line listing rather than using the M>V button, the selected memory is activated and the radio is left in memory channel mode displaying the memory tag.

Disabling Transmit

At the time of writing, I haven’t discovered a way of formally disabling transmit, and the minimum transmit power goes no lower than 5W. Since my main interests are around shortwave listening, utility stations and an occasional data mode QSO, I have not fitted the microphone to the radio. In that configuration at least, there is no danger of me manually transmitting into a receive antenna by accident.

Outdoor Power

Reports vary on the power consumption of the FT–891. It certainly isn’t as high as the 2.0A documented in the user guide.

While some sources claim values in the region of 1.0A, my power supply shows around 0.4A at 13.8V when receiving a typical HF broadcast. You will notice where some of that power goes quite quickly, as part of the radio gets warmer.

To save weight, my preferred power supply in the field is usually a lithium battery designed to jump start smaller engined cars. This versatile 12V battery also supplies 5V USB power to phones and tablets, and can even charge laptops.

In Conclusion

Control ergonomics and screen size are factors that can detract from shortwave listening on these kinds of radios, with smaller speakers and menu options for features normally at your fingertips.

Despite this, I’m happy with the audio, and I like the emphasis on mid-range frequencies in its audio spectrum. The digital noise reduction is impressive and can tackle significant QRM environments, but for outdoor listening may not be your first port of call.

Memory presets can make tuning less laborious, while assigning key listening tools to the customisable front panel buttons should reduce the need to access menus. I may consider defining some stations with known co-channel issues to memory with preset LSB and USB variations, to allow rapid responses to interference in future.

In good conditions, I suspect there is little difference between the FT–891 and FT–817ND for general listening. The FT–817ND has produced some of my best recordings of Shortwave Radiogram. The newer radio however brings many advanced tools to bear on more difficult signals, while its band scope and full sized VFO tuning dial enable desktop style shortwave exploration.

The ICOM IC–7200 is constrained by interference at home, biding its time for when the solar cycle swings back. When it’s been out on field days, it has always been a strong performer for broadcast listening. All the important controls are upfront, but is not a trivial thing to transport on foot. While the FT–891 has impressive DNR chops, I think I prefer the ability of the IC–7200 to apply noise reduction in incremental steps. Perhaps the algorithm approach will grow on me in time.

Any amateur radio operator using the FT–891 should have no trouble using it for shortwave listening. It attracts a lot of positive reviews for its ham radio capabilities, and it looks like those features carry across for listening to the world too.


An excellent review, Mark! Thank you for sharing.

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.

Photo from the 2019 Tokyo Ham Fair

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.

IC-705 and Elecraft T1 ATU at Toxaway Game Land

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:

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.

What’s your favorite general coverage transceiver for shortwave listening?

The Elecraft KX2 doing a little coastal SWLing.

Yesterday, at the (Virtual) 2021 Winter SWL Fest, I gave a presentation about QRP general coverage transceivers that I regularly use for shortwave broadcast listening (SWLing).

My discussion was limited to QRP–or low-power–transceivers designed for portable use, but they only represent a small fraction of the new and used transceivers on the market.

So what is “general coverage”––?

A ham transceiver with “general coverage” means that the receiver portion of the radio is not limited to the ham bands only; these receivers typically receive between 100 kHz and 30 MHz (i.e., the full medium and shortwave radio spectrum). Many transceivers, starting in the 1980s, employed a general coverage design as a feature of the radio. Some radios implemented general coverage receiving better than others. In most cases, there was a compromise to performance when the receiver was opened to general coverage reception, so many manufactures held to a ham-band-only platform to optimize performance where hams sought it most. Today, receiver architecture can better accommodate general coverage without compromising sensitivity and selectivity on the ham bands. This is especially true with new SDR-based transceivers that employ direct conversion or a hybrid architecture.

My favorite?

My current favorite is the new Icom IC-705. I purchased this rig last year and have done a tremendous amount of SWLing and MW DXing with it. I love its overall performance, portability and recording/playback features.

What’s your favorite?

 

I’m betting a lot of us use transceivers for shortwave broadcast listening.

What’s your favorite general coverage rig and why? I’m also curious how many of you almost exclusively use a transceiver for SWLing. Please comment!

The best transceiver for a new ham and seasoned SWL?

The Yaesu FT-890: One of many general coverage HF transceivers spotted in the 2017 Hamvention flea market.

Many thanks to SWLing Post reader, Joe, who writes:

I’ve been practicing for my Technician ham radio license here in the US and am ready for the test. I’m already looking at HF transceivers even though I don’t have my General license yet.

Here’s what’s important to me:

  • I will still do a lot of SW DX
  • Something that has at least decent audio
  • Something that isn’t too too huge; though I’m a little flexible on size
  • I need something that has a receiver that handles weak DX well

I’d be comfortable spending $500 any day all day no problem. Anything higher than that and I’d really have to think it’s an investment in my radio future.

Thanks for your question, Joe, and allowing me to post it here for comment as this is one I’m frequently asked.

First of all, congratulations on studying for and taking your ham radio license exam! I’m a ham and absolutely love the radio privileges my license provides.

At the same time, I’m still more of an SWL than a ham–meaning, I spend way more time chasing SWL DX than doing on-air ham operations.

With that said, I always seek radios that will serve me well as both a ham and SWL, if possible.

My humble advice

If we stick with your $500 budget strictly, then we’re certainly looking at used transceivers. That’s okay–there are many good ones on the market!

I posted the following review of general coverage transceivers a few years ago. The info in it is still very much accurate in the used market. I would suggest you give it a good review as it goes into more detail about the ins and outs of your first transceiver and the importance of leaving budget to purchase a good power supply:

 If you’re willing to spend a bit more than $500…

I’m a big fan of the Elecraft KX3 and Elecraft KX2. I have both and use them frequently.

Comparing the size of the Elecraft KX3 (top) and KX2 (bottom) at Elecraft’s Dayton Hamvention booth.

You can find the KX3 used for $700-900 (depending on options). The bare-bones model of the KX2 can be purchased new from Elecraft for $749.

Of course, something to keep in mind about the Elecraft KX series transceiver is that output power is limited to 12-15 watts. Some of the general coverage transceivers mentioned in our review have a much higher 100 watt output power.

Additionally, the audio fidelity (via the internal speaker) is not as good as many other general coverage transceivers. Audio amplification is not as powerful, because both transceivers are designed to operate on a small battery pack (a major plus in my world because I love field-portable rigs).

Since I do 90% of my radio work with headphones, audio amplification is not a problem for me and I’m quite please with both KX line transceivers. Many KX series owners purchase external amplified speakers to improve audio.

The LnR LD-11 tuned to the Voice of Greece.

While we’re looking at QRP transceivers, I would also recommend the LnR Precision LD-11. Its broadcast afidelity is even better (via headphones) than the KX2/KX3 since the AM filter can be widened to an impressive 9.6 kHz. It’s a top-notch transceiver and can be purchased new for $780 US. Click here to check out my full review of the LD-11.

The Icom IC-7200

Of course, as I mention in the general coverage transceiver review, the Icom IC-7200 is also a gem of a transceiver.

Keep in mind, the ‘7200 was such a popular radio that after Icom discontinued the model in January of 2016–due to overwhelming customer demand–they re-introduced it earlier this year. No kidding.

New, the IC-7200 is about $879 US, but they can be found used closer to the $650 – 750 mark. A very good value in my book. In fact, I’m very tempted to buy one as my 100 watt “shack and field” rig. It’s way more user-friendly on Field Day than my Elecraft K2/100 and, in many ways,  a better option than purchasing an Elecraft amp for my KX3/KX2.

Any other good suggestions?

The Kenwood TS-480SAT is full-featured, small, and has a detachable face plate. A very good general coverage transceiver.

There are hundreds of HF transceivers on the new/used market. I’m sure I’ve missed some excellent options in this post and my general coverage transceiver review.

The best general coverage transceivers for shortwave listening

This article originally appeared in the May 2014 issue of The Spectrum Monitor Magazine.


Icom-IC7200

The Icom IC-7200 has an excellent general coverage receiver

Like many amateur radio operators, I became interested in HF radio because of my real passion for shortwave radio listening. During my first fifteen years as an SWL, I relied on portable receivers, in my case, the Zenith Transoceanic, Realistic DX-440, and Grundig YB 400. The Zenith was my home radio; I traveled with the DX-440 and YB400. I felt like I had the world at my fingertips.

In the mid 1990s, as an undergraduate, I decided that I would pursue my ham radio license–while on my student budget, I dreamed about upgrading to a proper tabletop receiver like a Kenwood, Icom, JRC or Drake. But when I found out the real cost of buying an HF transceiver (gasp!) I realized that all of my resources would go into a transceiver, and the receiver would just have to wait.

The Icom IC-735 general coverage transceiver

The Icom IC-735 general coverage transceiver

Then, as I was studying for my license in 1997, ham buddy Eric McFadden (WD8RIF) invited me over to his house to test drive his Icom IC-735 transceiver. Eric, along with another friend/elmer, Mike (K8RAT) encouraged me to look for a used IC-735 for an affordable first HF radio.

I recall very well tuning around the ham bands at Eric’s QTH and being most impressed with how the IC-735 seemed to pull signals out of the static. It was my first time ever tuning a tabletop rig, and I was instantly hooked. Later, I asked Eric if the ’735 could also tune in shortwave radio broadcasters? His energetic response: “Sure! The ‘735 is general coverage,” then demonstrated by tuning to the 31M band.

Needless to say, I was absolutely amazed by the number of stations one could hear on this ham radio transceiver. Of course, its sensitivity surpassed anything I had ever owned, especially considering that the rig was hooked up to a proper outdoor wire antenna. I realized then that a ham radio transceiver and receiver–in the same radio–were within my financial grasp.

So, what is “general coverage”––?

A ham transceiver with “general coverage” means that the receiver portion of the radio is not limited to the ham bands only; these receivers typically receive between 100 kHz and 30 MHz (i.e., the full medium and shortwave radio spectrum). Many transceivers, starting in the 1980s, employed a general coverage design as a feature of the radio. Some radios implemented general coverage receiving better than others. In most cases, there was a compromise to performance when the receiver was opened to general coverage reception, so many manufactures held to a ham-band-only platform to optimize performance where hams sought it most. Today, receiver architecture can better accommodate general coverage without compromising sensitivity and selectivity on the ham bands.

Still, in 1997, my Icom IC-735 met all of my ham radio and SWLing expectations. For years, in fact, it was my main SWLing rig. Was the IC-735 as good as a proper tabletop receiver? No. The truth is that its filters and performance were most favorable for the ham radio bands. But as I mentioned, this compromise is much less profound in current transceiver design, and general coverage is status quo.

Benefits of general coverage

While the benefit of having a transceiver that can tune the full broadcast band may seem obvious, there are two reasons I always have at least one general coverage transceiver in my radio arsenal:

  1. Since I like to travel and save space, a small general coverage transceiver (e.g., the Elecraft KX3) kills two birds with one (portable) stone;
  2. If an emergency, such as a dire weather event were to occur, general coverage will allow me the ability to monitor international broadcasters and local AM (mediumwave) stations while still performing any emcomm (emergency communications) duties.

Another advantage to owning a proper HF transceiver is that, if you currently do not hold an amateur radio license, this may just be the push you need to get your ticket! All you’ll need to do is take two multiple choice tests (Technician and General) to unlock the full potential of your HF transceiver, and you’ll soon enjoy hamming it up with the rest of us.

Cons of general coverage

As I mentioned, general coverage transceivers can present something of a compromise in performance; after all, the rig’s main duty is to perform on the ham bands. Here are a few compromises to be aware of:

  • With a few exceptions, purchasing a ham transceiver is pricier than purchasing a comparable dedicated broadcast receiver
  • AM filters are often much narrower than broadcast receiver filters
  • In many radios, you may be faced with a choice of optimizing filter selections for ham radio use (SSB or CW) or broadcast use (wide AM filters, etc.)
  • Older general coverage transceivers (circa 1980s and 90s) may have somewhat compromised ham band receive performance
  • Some general coverage transceivers may actually lack AM mode. All broadcast reception will basically be tuned via SSB (or better known as ECSS)
  • General coverage transceivers typically lack synchronous detection

Another consideration: while anyone can purchase a general coverage ham radio transceiver, until you hold an amateur radio license with HF privileges, you cannot legally transmit using your radio. I doubt that any readers would consider doing this intentionally, but again your radio is designed to transmit, so this could be done accidently especially if you’re not familiar with transceiver functions. Transmitting unintentionally can have more than legal repercussions: 1) if you transmit with a mis-match between your transmitter and antenna, you could harm the finals in your transceiver; 2) you could damage your radio and/or antenna if using a receive-only antenna (like a mag loop); and 3) you could even receive RF burn. To avoid this, and make it foolproof, search the web for modifications to temporarily disable “transmit” on your radio if indeed you never intend to transmit.

A note about power supplies

My trusty Astron Power Supply

My trusty Astron Power Supply

Unlike stand-alone receivers, most general coverage transceivers require an external DC power supply. If you do not have a power supply, you will need to fit this into your budget. Power supplies can be costly, but also an investment in longevity. With a little knowledge up front, you can be selective and save on your power supply purchase. As I have been using the same power supply (an Astron RS-35A) since 1997, I turned to my friend Fred Osterman, president and owner of Universal Radio, for suggestions on power supplies currently in production.

Fred pointed out that if your only goal is to power a transceiver for the receive function, there is no need to invest in an expensive power supply. He suggests a reliable, regulated power supply, such as their popular $35 (US) Pyramid PS-4KX: at 3.5 amps; indeed, the PS-4KX will be more than enough power for any transceiver in receive mode.

Of course, if you plan to transmit at full power–and unless you have a QRP radio–you will need a power supply that can handle the load. For this purpose, Fred suggests two excellent options:

Again, I’ve had my trusty Astron RS-35A since 1997, so once you’ve invested in a good power supply, you should be all set for many years–and radios–to come.

Transceivers: Good bets for $1,600 US or less

There are dozens of general coverage transceivers currently on the amateur radio market. Indeed, I don’t believe there are any rigs now in production that do not have a general coverage receiver, or at least the option to add it. Prices vary greatly, but I will assume that most SWLs that are considering the leap into amateur radio will want a radio that costs less than the price of a tabletop radio/transceiver combo. Just to keep things simple, we’ll limit our list to $1,600 US or less, beginning with the least expensive option.

Alinco DX-SR8T ($510 US)

The Alinco DX-SR8 has a detachable face plate

The Alinco DX-SR8 has a detachable face plate

The DX-SR8T ($510 US) is one of the most affordable general coverage transceivers on the market. To be clear, the DX-SR8T lacks many of the frills and features of pricier rigs, but it’s a surprisingly good transceiver and, of course, general coverage shortwave receiver. Indeed, Alinco actually markets a receive-only version of this radio (the DX-R8T, $450US); it is identical in every respect to the DX-SR8T, but simply has no transmit function.

While I have only used the DX-SR8T on a few occasions, I have spent a couple of years with the DX-R8T, and even reviewed it extensively in the SWLing Post. My DX-R8T began life as a review unit that I purchased––it was an early production unit, and even retained the transmit LED indicator found on its sibling, the DX-SR8T. Consider paying the extra $60 US for the DX-SR8T, and you’ll have a basic, full-featured transceiver.

You can purchase the IC-7200 from Universal Radio or other ham radio equipment retailers.

The Icom IC-7200 ($900 US)

The IC-7200 delivers a lot of performance for a sub-$1,000 price. Its general coverage receiver will rival that of the venerable R75, and its AM filter can be widened to 6 kHz. Ergonomics are better than average. Plus, it has Icom’s twin passband tuning: the IC-7200’s general coverage receiver actually tunes from 30 kHz all the way to 60 MHz. The IC-7200 is a fantastic value.

The Elecraft KX3 ($900 kit; $1,000 factory pre-assembled)

The Elecraft KX3

The Elecraft KX3

The Elecraft KX3 is my general coverage transceiver of choice. There’s so much about this radio that I like: it’s nearly as compact as my portable shortwave radios, it’s a full-featured transceiver, it can operate on batteries, it has good ergonomics, and is made and supported by Elecraft, right here in the USA.

Its sensitivity and selectivity rival radios three times its price. The only negative I can point out about the KX3, in comparison with many other general coverage transceivers, is that its AM filter is limited to a width of 4.2 kHZ. When I first learned of this, I thought it would be a deal-killer for me. But I was wrong. The audio sounds much more robust and “wide” than I would ever have guessed. It’s excellent. Want more details? I made an extensive review of the Elecraft KX3 in the SWLing Post.

You can purchase the Elecraft KX3 directly from Elecraft.

Note: Elecraft tech support can instruct you in disabling “transmit” on the KX3, if you wish.

Update: Also check out the KX3’s new sibling, the Elecraft KX2.

The TS-590S has an excellent general coverage receiver and brilliant audio fidelity. With one of the lowest noise floors in the business, the 590S is well respected amongst amateur radio operators and shortwave radio listeners. If you doubt this, see how the TS-590S compares on Rob Sherwood’s receiver test data page.

You can purchase the Kenwood TS-590S from Universal Radio or other ham radio equipment retailers.

Updates

[June 13, 2020] Since originally publishing this article, a number of general coverage transceivers have hit the market. Many of them are very affordable.  Here’s a short list of additions:

Looking to spend a little more?

Icom-IC-7600

The Icom IC-7600

If you happen to be a ham looking to upgrade their transceiver for benchmark performance, you may be willing to dedicate more funds to your purchase. My buddy, Dave Zantow (N9EWO), a discriminating reviewer for the late great Passport To World Band Radio, is very pleased using his Icom IC-7600 for broadcast listening. He told me recently, “[The IC-7600 is] not perfect, of course, but does perform near excellent and also has a great display [with] a very useful spectrum scope.” Dave has a full review of the IC-7600 posted on his website.

The Ten-Tec OMNI VII

The Ten-Tec OMNI VII

I have also been impressed with the superb broadcast reception of the Ten-Tec OMNI VII ($2,800 US), Ten-Tec Eagle ($1,800 plus wide AM filter) and Orion series transceivers. While the OMNI VII and Orion II will set you back more than $2,000, used original Orions can be found for $1,800 and even less. Ten-Tec still services all of their radios at their headquarters in Sevierville, Tennessee.

Used transceivers

If you would like to save some money, consider searching the used market for one of the radios mentioned above. Alternatively, look for some of these select transceivers that are no longer in production, but are known to have capable general coverage receivers (do note that what follows is simply a selection, not a comprehensive list):

Keep in mind, when you purchase a quality used radio, you can get excellent value for the performance it will reward you. The flip side of this, though, is that if you purchase a radio that hasn’t been in production for over a decade, the chances of finding replacement parts become more difficult with each passing year.

For more hints on purchasing a used rig, check out our Marketplace page.

With the option wide AM filter installed, the Ten-Tec Eagle makes from an amazing broadcast receiver. They are available new from Ten-Tec, but can also be found used.

Summary

If you plan on investing in a fine communications radio, it may be best to economize by investing in a good general coverage transceiver. For the prospective ham, the leap from a tabletop receiver to a fine general coverage transceiver may be less than $300. To prove my point, if an SWL planning to get a ham ticket asks about buying the venerable Icom R75, I would encourage spending $250 to get the Icom IC-7200, instead.

Indeed, with modern receiver architecture, there is little reason not to invest in a good general coverage receiver that you can also use to communicate all over the world when you get your ham ticket. And, need I add, it’s fantastic fun for the money.
