Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors David Iurescia, William Lee, and Radio Ado for the following tips:


Waves of Hope at Nutley Public Library (Tap Into Nutley)

Saturday, March 27 at 2:00 p.m. via Zoom – Learn the true and inspiring story of centenarian Agnes Joan Negra.  During World War II, using her shortwave radio from her home in Nutley, NJ, Agnes listened to Radio Berlin each night and notated the names of U.S. Prisoners of War as they were announced.  Agnes then went on to send personal letters to each family to inform them that their loved ones were still alive.  Author, Nutley native, and Son of Agnes, Ronald along with his wife Valerie, will discuss the creation of this book and this inspiring story of his mother.  You must register in advance at nutleypubliclibrary.org/waves-of-hope to attend.  When registering you will receive a confirmation and one day before the event you will receive an email with log-in instructions through Zoom.[]

People will be listening to more radio when the pandemic is over: Ciaran Davis (RadioInfo)

“People have learnt that they can listen to radio in new ways and they will be listening to more, not less, when the pandemic is over,” according to HT&E chief executive Ciaran Davis.

Speaking to radioinfo this week, Davis explained that the company had “a very tough second quarter” in 2020, but the rest of the year turned out better than expected.

“There was a huge improvement in quarters 3 and 4, compared with that horrible quarter 2 where radio revenue was back 46%,” said Davis.

With about 30 people losing their jobs at the height of the pandemic, “regular communication and honesty was important in getting the staff through the worst of the pandemic.” It was “a very unsettling time” but the company “kept people involved and focused on the positive,” which kept the company performing well despite the tough economic conditions.

After early pay cuts, salaries have now returned to normal. “The revenue book was empty, so we had to take the decision to cut pay, but radio listenership and advertising has come back strongly and more quickly than we thought it would then… we were looking at some troubling numbers if the pandemic had of kept going.”

Luckily, the worst fears were not realised. HT&E revenue was 22% down on the previous year, but could have been a lot worse. The outlook seems positive for 2021.

“I think there was a perception that radio would suffer the same fate as out of home because people were not listening in the car during lockdowns, but it didn’t.

“We in the industry knew that our content is engaging enough, strong enough, local and live enough to be resilient. The emotional bond between listeners and their favourite stations and personalities meant that they easily switched to new platforms when they were at home. It took some convincing for the ad market to understand that this had happened, but they understood in the end.

“This is an exciting time. I think people have learnt that they can listen to radio in new ways and they will be listening to more not less when the pandemic is over.”[…]

RTÉ to cease radio transmission on DAB network (RTÉ)

RTÉ is to cease transmission of its radio services on the Digital Audio Broadcast (DAB) network on 31 March.

However, its digital radio services, RTÉ Gold, RTÉ 2XM, RTÉ Radio 1 Extra, RTÉ Pulse, and RTÉjr Radio, will remain available on other platforms.

In a statement, the broadcaster said the move to cease DAB transmission was driven by three main factors – the fact that DAB was the least utilised platform in Ireland; that RTÉ is the only Irish broadcaster on the DAB system, and cost avoidance.

A public information campaign will be held to show customers how they can continue to access the digital stations.

In 2019, RTÉ had announced that its digital radio services would cease transmission as part of cost cutting measures.

However, although the DAB service will stop in March, the stations will now still be available on other platforms.

The broadcaster said this is due to the value audiences still derive from them.

The latest JNLR report, Radio in a Digital World, compiled by Ipsos/ MRBI, found that while 8% of the population in Ireland (330,000 people) are accessing radio stations via digital means, the smallest number in this cohort opt for DAB.

According to the report, just under 5% of adults in Ireland listen to radio via a mobile device, 2% listen on a PC, around 1.5% listen on a smart speaker, 0.6% listen on a TV set and 0.5% DAB. 77% of adults in Ireland listen to radio on FM.

One Megawatt of Peak AM Power – Saving the Voice of America Delano Relay DL-8 (YouTube)

In 2007, the Voice of America ceased operations at the Delano Relay site in Central California. The site is destined to be bulldozed along with several relics of Collins Radio Company’s Broadcast Communications Division. The Collins Collectors Association, with assistance from the Antique Wireless Association, hatched a plan to retrieve one of the Collins 821A-1 250 KW Shortwave Transmitters from the site and place it on display for all to see. This presentation gives some history of VoA and the Delano site and follows the disassembly and relocation of Delano Relay DL-8.

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:

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.

Check out our survey results from an Icom IC-705 blind audio test.

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!

Summary

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

POTA activation of the Blue Ridge Parkway

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.

AM Dxing with the Sangean PR-D15

Guest Post by Troy Riedel

Since the demise of my Sony ICF-SW100, I’ve decided to do some AM Dx’ing. A few years ago I purchased a Sangean PR-D15 as my dedicated “AM Dx Radio”. Despite owning it for a few years, I hadn’t yet really put it through its paces.

Note: My 1994 Gründig Yacht Boy 400, with its 150mm (5.9″) ferrite rod antenna, performs splendidly on AM and until this purchase, the YB400 was the radio I grabbed for AM Dx.

At the time of my purchase – if my memory is correct – the other models I had considered were the CC Radio 2 (now discontinued), the CC Radio 2E (it was a relatively new release at the time), and the Original CC Radio EP (now discontinued & replaced by the CC Radio EP Pro).

Admittedly, part of my decision was based on cost. At the time, the CC Radio 2 & 2E were priced over 2x the cost of the PR-D15 and the CC Radio EP was $15-$20 more when shipping was added. Besides the cost, I chose the PR-D15 based on a few things I had read online. But the aspect that really appealed to me is the 200mm (7.9”) Ferrite Rod Antenna and that compared favorably with the C. Crane offerings (yes – ferrite size isn’t everything, but it is an important consideration). So after having read online comments (reviews, discussion boards, etc.) about the PR-D15, I felt very comfortable with my decision and it wasn’t based on cost alone.

Frankly, I don’t really care how well my AM radio performs during the day (I hope this isn’t sacrilege). Why? During the day whether I’m in the car, working in the garage – whatever – I’ll typically stream my favorite station (NYC) via radio.com on my iPhone so I can pause, rewind, or pick-up where I left off. Until my Sangean PR-D15 can do that, I prefer to daytime stream. My “hobby” of AM Dxing is in the evening – to relax and have fun (and isn’t that what a hobby is supposed to be?). Keep that in mind as I reveal my results.

I intended to do my AM Dx Nighttime Test in one night, but I was getting so may stations that I had to extend it over two nights. I started each session around 8PM and they lasted until 11:30PM – 12AM (over 7.5-hours of testing on consecutive nights late this week). I had my PR-D15 on a lazy susan turntable and I had two nearby laptops – one to aid as an AM Station locator and the other I used to stream. Stream? Yes – to count as a recorded station I had to get a positive station ID. However, many radio programs are syndicated. Syndicated radio (and ESPN radio) can go on seemingly forever between station IDs. If I didn’t get a station ID within 15-minutes, I used the second laptop to go to the web site of the station I believed it to be to “listen live” to see if the radio and the stream matched-up (luckily live web streams are slightly behind live terrestrial radio so the IDs were easy). Often by the time I had given-up and gone to my 2nd laptop, I’d finally get an on-air station ID. I just didn’t want to waste too much time on one station and miss other stations.

Since my test extended for 2 nights, on night two I quickly dialed-through nearly all of the stations I confirmed on night one to make a quick re-confirmation they were still audible on the 2nd night.

Since I captured so many stations, I was overwhelmed trying to finish and thus I feel this test is still incomplete. My wife typically ends all of my radio playtime (my man cave is a “sitting room” off the side of the master bedroom & there is no wall – no door – so it’s completely open). But my wife and my step-daughter have a weekend out of town in mid to late March. And that means I can stay up all night and do one non-stop test session. Is it bad to say that I cannot wait to be alone?

My QTH is ~ 35-miles east of RIC (Richmond, VA) Airport. The tables below (broken into three files) are my results. Some frequencies have multiple station IDs – since when turning the radio and nulling signals, sometimes one station disappeared and another jumped onto the dial. If/when I post an update of my all-nighter, I’ll add another column to the spreadsheet to include the transmitter strength for better context. It should also be noted that I recorded straight-line distances & not driving distances (via an online straight-line/GPS calculator).

I was impressed that I successfully captured three Iowa stations. And though I find it almost unfathomable, I truly believe I was on the verge of successfully logging a station in Sandy, UT which is over 2000-miles away (there are only six stations assigned to the 1640 frequency, and given the content I [barely] heard, all indications are that it was KBJA)!

I also believe I captured at least one Super-Clear Channel station from Mexico, but unfortunately I just couldn’t successfully verify the station ID. I hope to have a future opportunity to add it to my list.

My ultimate goal is to: (1) compile & maintain a spreadsheet of every AM station that I am able to successfully ID; and (2) maintain a record of the most AM stations I was able to ID in a single one-night, non-stop session.

Despite being somewhat incomplete, I’m impressed by my results. I’m interested to see what you think so please post your comments below!

I should note that my results are strictly off the internal ferrite antenna – no external antenna, no passive loop antenna was used to enhance any signal.

Chuck’s re-capped GE Superadio II might set a new AM BCL benchmark

I recently took delivery of a better-than-new classic solid-state portable broadcast receiver: the venerable GE Superadio II.

This Superadio II was generously given to me by SWLing Post contributor, Chuck Rippel (K8HU), who has–in his spare time–been re-capping and restoring all three of the GE Superadio series models and bringing them back to life. Chuck wanted to send me one of the units he’d recently finished, knowing that it might help me when doing AM reception evaluations. He insisted “no strings attached.”

Besides thank you, all I can say is…

Wow–!

Note angels singing in the background.

When I received the Superadio II a week or so ago, I removed it from the box and it looked brand new; even sporting the original “Headset Capable” grill sticker.

This is a case, however, of a refurbished radio likely out-performing the original.  Here’s a list of the main modifications:

  • All of the original dry capacitors replaced with Nichicon Audio Grade components
  • FM AFC and AM and FM IF and RF sections have been aligned
  • Rebuilt the volume control

I’m sure there are other modifications Chuck didn’t mention.

Chuck told me each radio takes a full day to restore. Some of the alignment, rebuilding, and re-capping is surprisingly tricky and varies with each of the three models. Why is he doing this?

Chuck told me, “My enjoyment comes from giving these radios a new lease on life.”

A new lease on life, indeed!

Last weekend, we had a break in the weather–and I had a short break in my schedule–so I took the GE Superadio II, GE 7-2990A, C.Crane CCRadio3, and Panasonic RF-2200 outdoors for some fresh air.

It was late afternoon and, frankly, I didn’t have the time to do a full comparative session, but having spent the better part of an hour tuning around and comparing the characteristics of each radio, I decided to make a short video to share.

The video features the GE Superadio II, but I speak to some of the pros and cons of each model. Keep in mind, this is very much a casual/informal comparison:

Click here to view on YouTube.

The SR-II not only has the best audio fidelity in this bunch, but it’s also extremely stable and has no noise floor to speak of. No doubt, this is the result of those Nichicon Audio Grade components and a skilled technician.

Side note: Chuck is well-known in the radio world because he used to restore the Collins R390A which must be one of the most mechanically-complicated receivers ever made.

I haven’t even properly tested the SR-II on FM yet because I couldn’t pull myself away from the mediumwave dial that afternoon!

I asked Chuck if he would consider refurbishing GE Superadios for other people and I think he would.  If interested, contact me and I’ll put you in touch. Else, Chuck might leave details in the comments section of this post.

He does currently have a restored GE Superadio II on eBay. I just checked and in his listing, you’ll see a full description of the modifications made.

Click here to view on eBay.

Chuck, thank you once again for sending me this SR-II. It’ll become a permanent addition here at SWLing Post HQ. Again, I’m simply amazed at the audio fidelity of this 1980s era receiver. Honestly, I don’t think there’s anything made today that can even compare.

And thanks for doing your bit to refurbish these classic portables!

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Mike, Troy Riedel, David Iurescia, and Bob Janney for the following tips:


Ham Radio Signals From Mars (Spaceweather.com)

Ham radio operators are doing something that until recently only big Deep Space Networks could do. “We’re monitoring spacecraft around Mars,” says Scott Tilley of Roberts Creek, British Columbia, who listened to China’s Tianwen-1 probe go into orbit on Feb. 10th. The signal, which Tilley picked up in his own backyard, was “loud and audible.” Click to listen:

The signal Tilley received from Tianwen-1 is dominated by a strong X-band carrier wave with weaker side bands containing the spacecraft’s state vector (position and velocity). Finding this narrow spike of information among all the possible frequencies of deep space communication was no easy task.

“It was a treasure hunt,” Tilley says. “Normally a mission like this would have its frequency published by the ITU (International Telecommunications Union). China did make a posting, but it was too vague for precise tuning. After Tianwen-1 was launched, observers scanned through 50MHz of spectrum and found the signal. Amateurs have tracked the mission ever since with great accuracy thanks to the decoded state vector from the probe itself.”[]

Open letter to PM, Ministers calls for international service to be strengthened, not cut (RCI Action Committee)

The following open letter was sent February 15, 2021 to Prime Minister Justin Trudeau, Deputy Prime Minister Chrystia Freeland, Foreign Affairs Minister Marc Garneau, and Canadian Heritage Minister Steven Guilbeault asking them to maintain the integrity of Canada’s Voice to the World, Radio Canada International (RCI).

Thirty-two signatories, including former Prime Minister Joe Clark, former Canadian ambassador to the United Nations Stephen Lewis, author-composer-songwriter-film director Richard Desjardins, author Naomi Klein, and actor Donald Sutherland, ask that the CBC/Radio-Canada policy announcement of December 3, 2020 be blocked, as well as any changes to RCI, until RCI staff, along with an assembled group of qualified people outside CBC/Radio-Canada, can propose a plan to rebuild the international service.

The signatories say the plan should devise a form of financial and editorial autonomy for RCI. And outline a path to follow to restore the international mandate and effectiveness of Radio Canada International in the context of today and the future.

Prominent Canadians rally to save Radio Canada International one more time (Toronto Star)

OTTAWA – A group of prominent Canadians is calling on the CBC to rethink its decision to significantly cut staff and rebrand the globally focused Radio Canada International to focus on domestic news.

Wojtek Gwiazda, spokesman for the group trying to save RCI, says the CBC is planning to cut 13 full-time staff and three contract jobs from a staff of about 20.

They’ve sent Prime Minister Justin Trudeau a letter signed by 32 prominent Canadians, including former prime minister Joe Clark, former Canadian ambassador to the United Nations Stephen Lewis, author Naomi Klein and actor Donald Sutherland asking for the decision to be reversed.

Gwiazda says the new CBC policy will focus almost exclusively on producing programming for ethnic communities and the ethnic media inside Canada, instead of directing programming to an international audience.

Gwiazda says the move is a violation of the Broadcasting Act and order-in-council that created RCI in 1945.

In the December memo to RCI staff, the CBC said it was “modernizing” the news service for the 21st century by offering more translated CBC content in new languages such as Punjabi and Tagalog, which is spoken in the Philippines.

“By becoming more relevant, more visible or more widely available in the languages spoken by the largest number of new Canadians, the new offering will allow Radio Canada International to better connect and engage with its target audience. RCI will also make all this content freely available to interested ethnic community media,” says the CBC statement.

RCI is used to fighting for its survival since the CBC cut its shortwave radio service in 2012, which severed the broadcaster from its Chinese audience, said Gwiazda.[]

Save and rave! How a compilation of pirate radio adverts captures a lost Britain (The Guardian)

Fashion boutiques, shop-fitters and others advertised alongside raves on early 1990s pirate radio. Now, a new compilation is rediscovering a slice of the underground

ave you got that record that goes ah-woo-ooo-ooh-yeah-yeah?” It’s a scene familiar to anyone who spent time in a hardcore rave record shop in the 1990s – a punter asking for a tune they’ve heard on pirate radio or at a rave but they don’t know the title of, so they mimic the riff or sample hook hoping someone behind the counter recognises it.

A relic of pre-Shazam life, the ritual is preserved in an advert for Music Power Records aired on the pirate station Pulse FM in 1992. Nick Power, owner of the north London shop, recalls that no matter how mangled the customer’s rendition, “nearly always, you’d be able to identify the exact record they were looking for”. In the advert, Power plays the roles of both sales assistant and punter, pinching his nose to alter his voice. Almost 40 years later, the comic skit commercial has been resurrected alongside others on two volumes of London Pirate Radio Adverts 1984-1993, by audio archivist Luke Owen. Power is pleasantly bemused by this turn of events: “I can’t see there’d be a demand for radio ads, but there’s got to be someone out there who’s interested enough to buy it. I don’t see it being a platinum release, though!”

Released via his label Death Is Not the End, Vol 1 is available digitally at a name-your-price rate and for £7.50 as a limited-edition cassette tape – an echo of the format on which pirate listeners captured transmissions of hardcore and jungle. Back then, most fans pressed pause when the ad break started, which means that surviving documents of the form are relatively scarce. But what once seemed ephemeral and irritating has acquired period charm and collectability.[]

Klubrádió: Hungarian independent talk radio station leaves the airwaves

Many thanks to SWLing Post contributor, Balázs Kovács, who writes:

Hi Thomas,

As it was first announced last September as a possibility now happens: (one of?) the last major independent talk radio station in Hungary, the Klubrádió is forced off the air (92.9 MHz, Budapest region) from Monday (they will continue online).

“With the silencing of Klubrádió, it’s not just my morning commute that will suffer. Europe will have failed to stand up for its most fundamental values.”
A detailed article about the situation at the Independent from a former member of the governing party:
https://www.independent.co.uk/voices/eu-hungary-media-viktor-orban-b1799214.html

“There is a huge propaganda balloon built up by the government and Klubrádió was a little hole, a little piece of truth where the air could escape, so they had to close this little hole in the balloon and so they can construct their own propaganda world which does not reflect the realities of Hungary.”
The latest news in a shorter form at the CNN:
https://edition.cnn.com/2021/02/09/europe/hungary-klubradio-ruling-intl/index.html

“Finally, Ms. Karas says that Klubrádió still has a chance to be on air in case of a successful tender, but then right after this, she symbolically pulled the plug out of the transmitting equipment.”
Latest news release in response to the state from the radio:
https://www.klubradio.hu/adasok/klubradio-news-release-116227

with best regards,
Balazs

Balazs also shared this video which captures the last broadcast of Klubrádió:

Thank you for sharing this Balázs. I’m certain there are other SWLing Post readers in Hungary and throughout Europe who appreciated this independent voice over the air.

China bans BBC World News from broadcasting (BBC News)

China has banned BBC World News from broadcasting in the country, its television and radio regulator announced on Thursday.

China has criticised the BBC for its reporting on coronavirus and the persecution of ethnic minority Uighurs.

The BBC said it was “disappointed” by the decision.

It follows British media regulator Ofcom revoking state broadcaster China Global Television Network’s (CGTN) licence to broadcast in the UK.

Separately, the broadcaster Radio Television Hong Kong (RTHK) said it would stop relaying BBC World Service programming in the region, prompting condemnation from the BBC.

China’s State Film, TV and Radio Administration said that BBC World News reports about China were found to “seriously violate” broadcast guidelines, including “the requirement that news should be truthful and fair” and not “harm China’s national interests”.

It said that the BBC’s application to air for another year would not be accepted.

The BBC said in a statement: “We are disappointed that the Chinese authorities have decided to take this course of action. The BBC is the world’s most trusted international news broadcaster and reports on stories from around the world fairly, impartially and without fear or favour.”[]

In Our Time: The Invention of Radio (BBC Sounds)

Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of scientists and engineers built increasingly elaborate devices to produce and detect them. Eventually this gave birth to a new technology: radio. The Italian Guglielmo Marconi is commonly described as the father of radio – but many other figures were involved in its development, and it was not him but a Canadian, Reginald Fessenden, who first succeeded in transmitting speech over the airwaves.

World Radio Day 2021: Radio creates diversity and connects people (RADIOZENTRALE GmbH)

World Radio Day 2021: Radio creates diversity and connects people

World Radio Day will be announced by UNESCO for the tenth time on February 13th and once again refers to how important radio is for society and why it connects people.

Time to celebrate: UNESCO has proclaimed World Radio Day for the tenth time. In Germany, radio has been the everyday companion of people for a hundred years and, more than ever, radio is the medium of the hour. So this jubilee round provides many good reasons to pause and ask what radio means for each individual, society and the world. Radio itself does not take a break, it is on the air – every day and around the clock. Radio informs, entertains and offers a variety of programs, opinions and content. As a matter of course – and yet so indispensable – radio, both large and small, is the vital voice of people and for people.

At the global level, radio remains the most widely consumed medium

The world is changing rapidly. Social and political processes are becoming more dynamic due to new technologies, the communication network is getting faster and bigger and the challenges are becoming more important. In these processes, radio not only offers diversity, classification and orientation, but is also an integral part of opinion-forming because it is the platform for democratic discourse. This unique ability to reach a wide audience means radio can shape a society through diversity and is the place for those who want to speak up.

100 years of radio in Germany

In Germany, the medium for the ears and the head cinema is celebrating its centenary this year. The innovative strength of the medium and the trust base with listeners that has grown over the decades make it possible for radio to be the medium of the hour more than ever. It is the last mass medium and at the same time can digitally reach everyone with the entire range of offers. Radio is at eye level with people – both in terms of content and technology. Because just as society and people’s everyday lives have changed dramatically, so too have listening habits and content. What remains, however, is the great art of putting complex topics into understandable words and giving diversity a voice.

“Today we are experiencing that the world is changing rapidly. We face major challenges when I think of climate change, the current corona pandemic or the debates on racism, for example. The task of radio here is to inform and classify. To make the soft tones heard and to reflect the diversity of opinions, ”says Grit Leithäuser, Managing Director of Radiozentrale. “But the most important thing is to act at eye level with the listeners. This grown connection and mutual trust are something for both sides that one should be aware of and that it has to be preserved every day. Then, in a hundred years, radio will be the medium for people who listen on whatever technical route, in order to learn from one another and to live diversity. ”

World Radio Day was first proclaimed by UNESCO in 2012 and this year it has the motto: “New World, New Radio”. At the suggestion of Spain, the General Conference of UNESCO initiated World Radio Day in memory of the founding of United Nations Radio on February 13, 1946. The aim of the day is to make the public and the media more aware of the importance of radio, to the decision-makers Encourage information to be established and made accessible through the radio.

Further information on World Radio Day can be found at: https://en.unesco.org/commemorations/worldradioday

The generic initiative Radiozentrale sees itself as a common platform for public and private radio stations as well as generic companies in the radio industry. The radio center has set itself the goal of positioning the medium of radio and providing comprehensive information about the (advertising) medium of radio. More information: www.radiozentrale.de

DJ Broadway Bill Lee talks about today’s radio, AM DXing and much more (Stars Cars Guitars via YouTube)
