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:
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 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 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.

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.

I just received the following comment from Richard Levenson posted with this off-air recording of Radio Tirana on the Shortwave Radio Audio Archive:
Lots of fond memories listening to Radio Tirana, Albania going back to the late 1950’s. Their broadcasts back then were loaded with anti-West propaganda and more. Their interval signal is a classic to SWL people. Always remember the female announcer on the station. Her sign-off phrase was “and goodnight dear listeners.” This came after much in the way of negative propaganda. When she would say her sign off you got the idea she was tucking you into bed for the night. It had that quality and sincerity to it. Love to know who this person was or if she is still alive. Give you an idea how much SWL I did since around 1953 to present day.
Thank you for your comment, Richard! If you can identify this announcer with Radio Tirana, please comment with details!
In January 2021, C.Crane announced the latest addition to their radio line-up: the C.Crane CC WiFi-3.
C.Crane was one of the first radio manufacturers that embraced the world of Internet radio with their CC WiFi product line.
The WiFi-3 is the latest iteration and offers the following upgrades over previous models:
Before we dig into the CC WiFi-3, however, let’s first take a step back and talk about the current state of WiFi radios in general. This is an important consideration with any WiFi radio purchase these days.
Those of us who like WiFi radios appreciate a dedicated device that gives us the tactile experience of turning the knobs of a radio. We appreciate the simplicity of a dedicated listening device that doesn’t rely on a connected computer, tablet, or phone. In addition, most WiFi radios like the CC WiFi-3 don’t track your listening activity/habits like many internet radio listening apps and digital assistants do. They also don’t force feed you click-through ads.
But let’s face it: any of us who own Internet or WiFi Radios have had a rough couple of years. While WiFi radios can open the door to tens of thousands of radio stations across the globe, they do have an Achilles’ heel.
WiFi radios are Internet appliances with the ability to stream Internet content, but they’re not endowed with the ability to seek out stations in the wild and import their audio streams. WiFi radios rely on “aggregators,” or online databases of curated links to radio stations.
In the early days of WiFi radio, there were several models of radios on the market that linked to proprietary/niche aggregators, many of which eventually closed down without warning. When a WiFi radio loses its ability to link to an aggregator, it becomes no more than a pricey paperweight, especially if the WiFi radio doesn’t have traditional AM/FM reception as a backup or a back-end means to program radio station stream URLs directly.
Over the past two years, some of the major radio station aggregators have experienced issues that have truly frustrated their users. Most notably:
With this aggravating aggregator history, why would anyone want to invest their money in another WiFi radio? Let’s take a closer look at this new device from C.Crane so you can decide.
When C.Crane introduced the CC Wifi 3, they acknowledged the inherent issues with WiFi radios and how the Reciva closure affected their customers up-front. Here’s a statement they released:
We were happy to be one of first companies to offer ad-free Internet radio because it allowed anyone to listen to the world without a fee. Fifteen years ago, Ben, the founder of Reciva, had a small staff to create the software and volunteers around the world to help manage the station streams. We are sorry, but Reciva’s software will soon not work anymore. The software would need to be recreated from scratch. Even If this was done, it would not be possible for the existing radios to be compatible with this new type of software. This is the same way Apple and Microsoft might release a new operating system that is not compatible with older hardware.
We are working on a new radio called the CC WiFi-3. We will be testing the first pilot run of the new CC WiFi-3 in January with the first delivery by April if all goes reasonably well. There are still no ads or graphics to annoy you and nobody tracks your habits for advertising offers. It looks almost the same as the previous CC WiFi but has been upgraded in several ways:
- It uses a new 3rd party stream provider called Skytune.
- You can add your own streams (URLs) yourself so you are somewhat protected if the service fails for any reason.
- It is a little easier to use and it has a good built-in equalizer available.
- This radio comes with a 2 year limited warranty.
[…]The CC WiFi-3 comes with the risk of losing connection to Skytune’s server if they were to shut down in the future. As we have previously documented in our catalog and on the web: C. Crane has no control over content or the stream provider for Internet radios and cannot be responsible for Internet radio programs or availability.
I love this about C.Crane: they’re honest and transparent with their customers even during a new product release.
In January (2021), C.Crane sent me a pilot run, pre-production CC WiFi-3 for review and a thorough evaluation at no cost to me. Of course, I don’t typically share reviews of pre-production radios, but in this case, I believe the production model should function identically–or perhaps better–than my pilot model. I’m not concerned with variations in receiver sensitivity, selectivity, filtering, AGC, and noise floors as I would with a legacy receiver.
At first blush, the CC Wifi-3 could be mistaken for the CC WiFi-2. Other than the prominent model number, it has an identical form-factor and interface. Inside, though, there have been a number of updates we’ve already mentioned.
First thing I did, of course, was connect the CC WiFi-3 to the internet. It was a pretty simple process to go into the settings, have the radio find my WiFi service, and input the network password. If you have a long or complicated password, allow a few minutes to do this as the input method is character-by-character using the main front panel knob.
Once connected, the radio has access to the new Skytune aggregator to search for radio station streams. I’m familiar with Skytune because they are the aggregator also used by my recently reviewed Ocean Digital radio. I like how Skytune organizes their database allowing users to search by by location/region, popularity, genre, etc. I found most of the stations I enjoy in short order.
If Skytune doesn’t have the station you’re looking for, they make it easy to suggest an addition via their website.
Adding Presets couldn’t be any easier. I’ve been using the most simple method: finding a station, then pressing and holding the PRESET button. This will save the radio station to the next available preset with more than 100 slots available.
As C.Crane mentioned in their statement, even if the Skytune aggregator were to shut down in the future, the CC WiFi-3 makes it relatively easy to directly add your own streams by logging into the radio from a web browser.
First, make sure you’re using a computing device that is connected to the same WiFi network as the CC WiFi-3.
Secondly, find the IP address of your CC Wifi-3 by pressing the HOME button, then selecting SETTINGS -> INFORMATION -> NETWORK INFORMATION -> IP: (immediately below the signal strength information).
Note the IP address. Mine is currently 172.20.10.5 but yours will likely be a different number.
Next, open a web browser and in the URL bar, type in the IP address of your CC WiFi-3 radio and press Enter:
Your web browser will then load a page served up by your radio’s CPU (allow time for it to load):
From this page you can add, organize, and label your station presets manually.
The CC WiFi-3 owner’s manual actually gives you hints about how to find URLs for radio stations. There’s certainly an art to it.
First thing I did, in fact, was add one of my favorite AM radio stations (WAIZ) to the WiFi-3 directly by finding their main and backup stream URLs and adding them manually via the presets page. This instantaneously added them to the WiFi-3 presets:
This pleases me to no end because I’ve never been able to play WAIZ from one of my WiFi radios.
From the presets web page you can also control some basic radio functionality like volume up/down, mute on/off, and channel selection.
While this isn’t quite as handy as a dedicated app, I like the fact that I can load this presets page from my phone, tablet, PC, Mac, or Linux box. It’s universal and simple.
I’m happy C.Crane added Bluetooth to the CC WiFi-3 because it makes this already capable radio even more useful. As I write this portion of the review, in fact, I’m listening to music from YouTube via my MacBook Air streaming to the CC WiFi-3 via Bluetooth. Handy!
I prefer the audio from the CC WiFi-3 over previous models. It’s balanced and has hints of bass and treble. It is robust enough to fill a sizeable room with audio.
It isn’t anything that would impress my audiophile brother-in-law because, in the end, the speaker and enclosure are not very large. It does reproduce voice and music with ample fidelity for casual listening, however.
You can tailor the audio with 12 EQ settings included in the WiFi-3 settings menu. I like the Jazz preset.
In addition, the CC WiFi-3 has a line-out and headphone jack that makes it easy to export audio to a component stereo system or amplified speaker system. (Note above the “Not For Resale” label on the back of this pilot/pre-production unit.)
The CC WiFi-3 also ships with an excellent full-size remote control. I love how much functionality this remote offers, making it much easier to navigate and control the radio from across the room. I also much prefer the form factor of this remote compared with the small credit card-sized remotes with membrane buttons.
Every radio has its pros and cons. When I begin a review, I take notes from the very beginning so that I don’t forget some of my initial impressions. Here are the notes I made for the CC WiFi-3 pre-production/pilot model:
Pros:
Cons:
If you’re not intimidated by the “aggregator aggravation” we mentioned early in this article, I would suggest you give the CC WiFi-3 a try. Since the WiFi-3 offers easy, open access to add your station streams manually, you always have a backup if, for instance, the Skytune service were to unexpectedly close down in the distant future.
For $119.99 US, you’ll be purchasing a radio from a company that takes care of their customers.
Indeed, C.Crane was so upset by the unexpected closure of Reciva, they have offered their existing CC WiFi customers the following options:
This is a one-time offer from C. Crane. This offer will end June 1, 2021.
To my knowledge, no other radio manufacturer or retailer has made an offer like this to compensate for the loss of the Reciva service. Kudos to C.Crane for giving their customers options and discounts.
C.Crane expects to have the CC WiFi-3 in stock and shipping in June 2021. We’ll post updates on the SWLing Post when they become available.

Woodland Operation in North Hampshire
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.
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:
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.
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.
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.
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.
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 |
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.
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.
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.
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.
The Yaesu FT-891 must be the most popular HF transceivers Yaesu sells today. So many of its users rave about its performance and audio characteristics. Mark, thank you for sharing your experience with the FT-891 as an SWL!

The following review was first published in the February 2021 issue of The Spectrum Monitor magazine:
It sometimes seems that one of the biggest enemies of a radio enthusiast these days is RFI (radio frequency interference), which is to say, human-originated noise that infiltrates––and plagues––vast chunks of our radio spectrum.
Yet I believe RFI has, in a sense, also managed to energize––and even mobilize––many radio enthusiasts. How? By drawing them out of their houses and shacks into the field––to a local park, lake, river, mountain, woodland, or beach––away from switching power supplies, light dimmers, street lights, and other RFI-spewing devices.
Shortwave and mediumwave broadcast listeners have it easy, comparatively speaking. They can simply grab a favorite portable receiver, perhaps an external antenna, then hit the field to enjoy the benefits of a low-noise environment. In that a portable receiver is something of a self-contained listening post, it’s incredibly easy to transport it anywhere you like.
Ham radio operators, on the other hand, need to pack more for field operations. At a minimum, they need a transceiver, an antenna, a power source, not to mention, a mic, key, and/or computing device for digital modes. Thankfully, technology has begun miniaturizing ham radio transceivers, making them more efficient in the use of battery power, and integrating a number of accessories within one unit.

Case in point: in 2019 at Tokyo’s Ham Fair, Icom announced their first QRP (low-power) radio in the better part of two decades: the Icom IC-705.
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:
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.
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)!
Funny: the IC-705 is the first new transceiver I’ve purchased with a color box.
If you’ve ever owned or operated the Icom IC-7300, you already know how to operate many of the functions on the IC-705. The user interfaces on the touch screens are identical. Features that are unique to the IC-705 are easy to find and follow the same standard Icom user-interface workflow.
Having less front faceplate real estate, the IC-705 has less buttons than the IC-7300––about 11 less than its big brother, to be exact. However, the twin passband, gain, multi-function knob and encoder are in the same positions and layout as on the IC-7300.
And if you’ve never used an IC-7300 before, no worries: this is one of the more user-friendly interfaces you’ll find on a ham radio transceiver.
The build of the IC-705 is excellent. It’s not exactly hardened for the elements––there is no waterproof rating or dust rating, for example––but it gives the impression of a solid little radio, likely to withstand a bit of less-than-delicate handling. Yet even though it’s designed to be a portable field radio, I’ll admit that the front panel and especially the color touchscreen feel a little vulnerable. I do worry about damaging that touchscreen while the radio travels in my backpack.
The Icom LC-192
On the topic of backpacks, Icom released a custom backpack (the LC-192) specifically for the IC-705, Icom AH-705 ATU, antennas, and accessories. I did not consider purchasing this backpack, although I’m sure some operators would appreciate it, as it has dedicated compartments for supplies and the radio can be attached to the floor of the backpack’s top compartment. Again, I passed because I’m a bit of a pack fanatic and tend to grab gear that’s more tactical and weatherproof.

While its in my Red Oxx or GoRuck backpack, I house the IC-705 in a $14 Ape Case Camera insert. Eventually I want to find a better solution, but this does help pad the IC-705 while in my backpack and certainly fits it like a glove––hopefully protecting that touchscreen.
A number of third-party manufacturers have designed protective “cages” and side panels for the IC-705, but I’ve been a bit reluctant to purchase one because I feel they may add too much weight and bulk to the radio.
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.

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:
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 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.
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.

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.
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.
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.

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.
One of the brilliant things about the IC-705 is the fact that it has a built-in digital recorder. Both transmitted and received audio can be recorded in real time and saved to a removable MicroSD card. I made audio recordings of two broadcast stations on the 31-meter band as samples: the Voice of Greece (9420 kHz) and Radio Exterior de España (9690 kHz). The Voice of Greece was moderately strong when I made the recording and Radio Exterior was quite strong. Click on the links to download the .mp3 files for each recording:
Voice of Greece
Radio Exterior de España
I’ve also used the built-in digital recorder to record long sessions of my favorite shortwave, AM, and FM stations. Even with the recorder on, I can typically achieve hours of listening on one battery charge and need no other power supply.

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