This article appearing in the Washington Business Journal reports that President Joe Biden signed legislation that orders the sale of the Wilbur Cohen Building at 330 Independence Avenue, which has been headquarters to the U.S. Agency for Global Media (ex-Broadcasting Board of Governors) and Voice of America for many decades.
Relocation of the agency and VOA has been in the planning stages for the last several years, with the USAGM CEO and other officials claiming that savings from standing down the Cohen Building, which was constructed between 1939 and 1940, in stages would more than pay for the relocation.
However, sources inside the agency have doubts. The new building selected by the now outgoing CEO, Amanda Bennett, at 1875 Pennsylvania Avenue, NW — just a couple blocks from the White House, is currently just office space with no production/broadcast facilities.
A report by the consulting firm Deloitte lays out a multi-year timeline for the agency through 2027. It contains the following description: “New facility was previously only office space and does not currently have the infrastructures to support Broadcast Technology needs. Facility will need to be retrofitted to do so.”
The article by Ben Peters of Washington Business Journal says:
“Congress has directed the General Services Administration to sell the storied Wilbur J. Cohen Federal Building as part of the government’s ongoing efforts to offload underutilized real estate assets. The Biden Administration last week signed off on the Thomas R. Carper Water Resources Development Act of 2024 that, among its many provisions, requires GSA to sell the 330 Independence Ave. SW, located a crosswalk away from the National Mall, “for fair market value at highest and best use” no later than two years following the vacancy of its last remaining federal agency.
It goes on to note that USAGM and VOA are believed to be the only occupant of the building. At 1.2 million square feet, the Cohen Building far exceeds the area of the planned new headquarters building, but agency officials have asserted that much of the Cohen Building space was not actually used.
Nevertheless, employees are wondering how agency staff at current levels will be able to fit at 1875 Pennsylvania Avenue, and this has been the subject of questions at recent internal Town Hall meetings.
Washington Business Journal continues: “If sold, the Cohen building would join a growing list of federally owned properties that have been or remain in the process of being offloaded as the GSA accelerates long-standing plans to cut back the federal real estate portfolio. That work is expected to accelerate under the incoming second Trump administration.”
“USAGM last year signed a 15-year deal to relocate and downsize its offices from 698,000 square feet at the Cohen building into 350,000 square feet at the EastBanc-owned 1875 Pennsylvania Ave. NW. The deal represented by far D.C.’s largest fourth-quarter lease transaction, helping to move the District’s office vacancy rate down ever so slightly for the first time in years.”
The article also quotes a 2024 report by the Public Buildings Reform Board, which found that USAGM’s offices at Cohen were just 2% full between January and September 2023. The large office space there has a capacity of 3,431 workers but saw, on average, just 72 people actually using it each day during that period, the report said.”
The low occupancy of the Cohen Building came to the attention of members of Congress preparing reports on the abuse of telework and remote work by federal employees, prominent among which is Senator Joni Ernst (R-IA).
One photo of VOA’s near-empty newsroom, taken by a tourist visiting VOA, appeared on the World of Radio group, directly contrasting with what once was a vibrant VOA central news operation.
As Government Executive detailed here, Senator Ernst proposed “a trio of bills targeting Washington, D.C.,-area federal employees that would mandate agencies move staff—or their entire headquarters—out of the region, as well as more closely track teleworkers’ activities.
The Decentralizing and Reorganizing Agency Infrastructure Nation-wide to Harness Efficient Services, Workforce Administration and Management Practices—or DRAIN THE SWAMP—Act (S. 23) would require all non-national security agencies to relocate 30% of their headquarters staff outside of the D.C. area within one year of the measure’s enactment.
The Requiring Effective Management and Oversight of Teleworking Employees Act (S. 21) would “require agencies to measure the login data and network traffic—that is, the amount and rate of data flow—from teleworking federal workers’ computers to ensure that they are doing their jobs while outside of traditional work sites.
Another bill, Strategic Withdrawal of Agencies for Meaningful Placement Act (S. 22), would bar agencies from undertaking renovations or renewing the leases of their D.C.-area headquarters and instead require them to solicit bids from other cities to relocate outside of the national capital region. It is worth noting that 85% of the federal workforce already lives and works outside of the D.C. area.
Ernst directly cites low occupancy rates at agencies’ D.C. headquarters, saying she was “already working hard on my top priorities—to drain the swamp, save tax dollars and get federal employees back to serving the American people,” Ernst said in a statement.
A lot of history took place in the Cohen Building, including President Ronald Reagan’s visit, during which this photo was taken. I was in the building in the early years of a 34-year career with VOA when this visit occurred.
It’s clear that VOA and USAGM itself face potential downsizing especially at a time when the focus of the incoming second Trump administration is on reducing waste of taxpayer funds by federal agencies. The extent to which the agency has its budget (which stood at about $950 million in 2025) reduced remains to be seen.
The explosions/detonations of HT radios targeting the militant group Hezbollah in Lebanon continue to make headlines, with latest reports digging into the origins of the units and containing reaction from ICOM. This story is one of those rare occasions when the radio manufacturing industry is thrust into the spotlight.
“The lethal hack of Hezbollah’s Asian-branded pagers and walkie-talkies has sparked an intense search for the devices’ path, revealing a murky market for older technologies where buyers may have few assurances about what they are getting. While supply chains and distribution channels for higher-margin and newer products are tightly managed, that’s not the case for older electronics from Asia where counterfeiting, surplus inventories and complex contract manufacturing deals can sometimes make it impossible to identify the source of a product, analysts and consultants say.”
The Reuters report also noted:
“For Icom, one problem is that it stopped making the IC-V82 model in question a decade ago, around the time it started introducing holographic stickers as a protection against counterfeit products, the company said. The company has long warned about imitation products, especially of its older models. In fact, more than 7% of firms in Japan reported business losses from counterfeit products in 2020, according to the latest available report by the Japan Patent Office, with around a third of cases linked to China. Icom has urged that customers only use its official distributor network to ensure they are buying genuine products.”
This earlier Reuters report was published in The Jerusalem Post.
Another report, which quotes Ray Novak, ICOM U.S. representative, appeared in The Washington Post. It said ICOM was “[investigating the allegations, but early signs pointed to the walkie-talkies being counterfeit]”. ICOM had issued three statements on its website as of mid-September 20th.
Since my original Tecsun S-2200x review, I have run additional tests on the S-2200x and have the following observations, and responses to some comments. I continue to test this receiver, but conclude that really if one has to have just one radio – which I think is usually not the case – one cannot really go wrong with any of the Tecsun portables, whether the 2200x, or S-8800, H-501, or PL-990. With that said, here are my additional observations on the 2200x:
OVERALL RATING: At the end of my original main review, I said that assuming Tecsun can maintain a high level of QC in production, and considering that the important RECAL feature has been retained, and that the radio has no muting, I would give the S-2200x a 4.8 out of 5. This would increase if Tecsun can address the slight alignment issue on the rotatable antenna, the issue in which SQUELCH does not completely silence audio.
However, after extensive testing, I feel that the problem of SYNC losing lock and generally sounding unstable takes the 2200x down a few notches. At present, the receiver is an attractive package with its retro styling, really nice and smooth main tuning knob, no soft muting and recalibration. However, the fact that synchronous mode has still not improved over the H-501/PL-990 means I would rate the 2200x at no more than a 4.5. Had Tecsun taken steps to improve SYNC – if it’s at all possible using the current chips — the radio would easily be several rating points higher.
AGC/SYNC: SYNC mode on the 2200x struggles, especially with weaker signals and regardless of bandwidth. As an example, testing on 15,575 khz (South Korea) using the telescopic and an an external long wire showed that in synchronous, there was a good amount of “pulling” with the signal, which was only at a fair level. The question of whether Tecsun has made any changes to SYNC mode between the H-501/Pl-990 and S-2200x remains, and we would hope to hear from them on this issue.
Here is an additional video showing both the 2200x and a H-501x in SYNC mode on a strong signal. Both receivers exhibit some less than satisfactory SYNC performance, though the 2200x sounds a bit worse:
Reader comments always spark additional thinking. As one user observed, Tecsun could have added AGC FAST/SLOW/MEDIUM options in addition to providing AGC and adjustable manual gain. It is definitely a good thing that SYNC as well as LSB/USB operate not only on SW, but also in AM and LW.
SSB: One reader asked if SSB performance on the 2200x has “the same woeful SSB audio quality issues caused by AGC and a low cut off frequency of around 300 hz making the audio sound thin, lacking bass while on SSB?” The reader also notes that these are “issues with every single Tecsun and most other DSP radios and due to the cost of these radios one should expect perfect performing and sounding SSB.” To adapt a quote from one of my favorite Clint Eastwood movie lines (“Deserves got nothing to do with it”) in this case I will say that Perfect has nothing to do with it. We’re all enjoying a mini-boom in the appearance of new receivers – to expect absolute perfection from a DSP-based receiver is sadly, unrealistic. SSB on the 2200x is probably about as good as it can get. The fact that fine tuning on the 2200x is so smooth is a very good thing.
ANTENNA: I have tested the 2200x using telescopic versus external antennas, including a long wire, W6LVP, Wellbrook and Chameleon loops. Reception is further enhanced with external antennas. The three ATTENUATION positions on the 2200x help to keep any overloading down.
RDS: A number of users/viewers have commented on the absence of RDS in the 2200x. This is indeed a good observation – seems that it would have been easy for Tecsun to include this, and one wonders if the company will consider adding this as a feature not only in the 2200x but H-501/PL-990 as well. However, I believe that Tecsun has just chosen to not increase costs and thus, no RDS.
AC POWER: As everyone probably sees, there seems to be no way to run the receiver on AC power. There is a dual USB-A cube included in the package, but as we have found, running receivers while they are charging is not a good idea. The 2200x does appear to charge fairly quickly via the USB-C port. Anyone with radios using 18650 batteries should invest in at least one good quality charger – these are available at any of the well-known professional battery/flashlight online sellers.
TUNING KNOB: Yes, the main tuning knob still exhibits wobble. It’s a puzzle as to why this can’t be resolved, especially years after the original Grundig 750 emerged and the old models continued to have this issue for years. But the action of the knob itself is really smooth and it’s a pleasure to tune this radio, at least based on the sample I have here.
In the end, our purchase decisions are driven by a number of factors – some potential 2200x buyers may not be as concerned with ongoing SYNC issues, while others might reject a new receiver outright based on this issue. The 2200x offers basically the same features as the H-501/PL-990, but adds AIR band and an excellent mediumwave rotatable antenna, and these facts alone may be enough to justify a purchase of the new radio.

Tecsun Delivers The S-2200X – New Life For A 16-Year-Old Cabinet Design
by Dan Robinson
Note: Please see an addendum of updates at the end of this post.
Some months ago, I learned from Anon-co that Tecsun planned to release an update to the S-2000 receiver, which for the past 16 years also sold under other names such as the Grundig Satellit 750 and later the Eton Satellit 750 and Eton Elite 750.
To say that this radio was long in the tooth is an understatement.
I remember seeing one when they first came out back in 2008 and I was never very impressed. To me, the radio looked like a toy, and the performance did not impress. The standout feature was the top-mounted rotatable antenna for MW/LW reception. That was popular with those of us who own the Panasonic RF-2200 and it’s a great tool for MW.
Grundig Satellit 750
While popular with a certain segment of the listening hobby – beginners liked the 750 and even some veteran SWLs appreciated the retro design — the receiver was plagued by annoying issues, such as the famous wobbly tuning knob. It also had limited selectivity, no synchronous mode, and mediocre SSB.
In 2013, The Monitoring Times (Larry Van Horn) took another look at the radio with the following memorable comments:
[MONITORING TIMES 2013]
“Needless to say some folks were not happy with our review of the 750 including Etón. In retrospect, over four years later, I would not change one single word I wrote in that review. I believe we honestly gave a fair assessment of the unit that was shipped to us for review. If you read my previous review closely, you would see that most of my concerns back then had to do with quality control issues and most in our industry fully acknowledge that we were seeing some nasty stuff coming out of China back in 2008.”
So, measuring from 2008 when the first Eton 750 came out we’re now in 2024 and Tecsun has decided to preserve the cabinet design of the original radio while substantially upgrading the internals.
Enter the S-2200x
Photo by Anon-Co
Reviewers have obtained units from the first production run. Tecsun has provided long-needed upgrades that put this radio on the same playing field as the very popular H-501 and PL-990 portables.
The 2200x adds a dedicated SYNC mode with its own front panel button. AIR band is retained, though sadly coverage doesn’t extend up to give us the NOAA WEATHER frequencies.
My initial testing of the S-2200x shows that performance is excellent on SW, AM, and FM. In contrast with portables from other manufacturers, SSB performance is excellent – in USB and LSB, tuning is smooth with no “warbling” and using the fine tuning control is a pleasure. Continue reading →

Raddy RF-919 Receiver: Best Portable in Years – Held Back Only By Soft Muting While Tuning
by Dan Robinson
It’s quite extraordinary that in these days of reduced use of shortwave some manufacturers continue to develop portable receivers for the worldwide community of radio listeners. We have the Choyong LC90, which for the first time attempted to combine HF, MW, FM and Internet radio (still a work in progress). And now out of nowhere comes the Raddy RF919.
Like many receiver enthusiasts, I was excited when I saw the first photos and videos of the 919, by Shenzhen Hanrongda in China. The company has an amazing number of portables in its lineup–in addition to the 919 there are the: RF320, RF760, RF747, RF75A, and RF750 along with various hand crank emergency sets. The RF919 under the Raddy label also sells as the Retekess TR113 (which can be seen on its Amazon page).
It is interesting that the RF919 (TR113) appeared on the market just as the Choyong receiver continues to experience growing pains, but obviously both had been in the planning stages for some time. One of the strengths is its very decent SSB performance, though see my comments below about one of the issues with the RF919.
The number of reviews of the 919 by YouTube influencers is rapidly increasing as the radios get into the hands of more users. For the purposes of this commentary I won’t go into every single feature other than to observe the high points. And here’s a headline – from a software standpoint this is a very complex radio with a steep learning curve requiring regular looks at the manual. But enough use brings familiarity with the many features it offers:
Displays
The RF919 has two superb displays: a main information center under which there are buttons for activating various functions and options, and a second beautiful signal level screen that has a lot of information on its own, under which there are four buttons for TIME SET, ALARM, DISPLAY, and SLEEP. These displays are probably the best we have ever seen in a portable, offering 7 colors selectable from the front panel! The Eton Elite Satellit (no longer made) offered a few colors on its display but it was nothing like this. Raddy publicity materials focus on this:
“Unlike other radios, you can choose and set your favorite backlight color to match your style or mood, all while staying updated with a clear 3.54-inch main screen that shows reception status. It’s not just a radio; it’s an extension of your personality.”
Body Design
The 919 is quite a throwback to such classic receivers as the SONY ICF-5900W and other “military style” portables from decades ago – one user noted the similarity to the old National Cougar 877.
The 919 has a solid, confident, body with a space at the top rear that functions as a hand grip. On top are two jacks for a LOOP ANTENNA, and a mobile WHIP style antenna with an OFF/ON rotary switch. That switch is awfully close to the LOOP jack. On the back is a 3.5 mm antenna jack with a three position slider control for specific tuning ranges. The backstand is basically the same type found on the Tecsun H-501. One wishes that there would have been a rubber friction grip placed on it and that it had some additional tension to allow it to hold the radio up in other degree positions.
Antenna
The telescopic whip antenna is impressive – robust, and notably designed to work while the radio is positioned on a desk using its backstand, something that the Choyong LC90’s antenna is not able to do.
I will note that the whip antenna cannot be extended up and out of the radio cabinet which limits it to a single angle when the radio is used with the backstand – placement of the 919 left carrying strap hook on top left is the limiting factor here.
Again the 919 telescopic design is a contrast to the LC90 which both lacks a backstand, and flexibility in the antenna.
A major headline is the manual antenna tuning feature on the RF919. Utilizing the rear antenna jack and switch with MW, SW 1, and SW 2 options, along with the side adjust knob, the user can fine-tune signal strength, with the secondary screen providing real-time viewing of signal strength changes. On top of the radio, there is a mini jack input next to an ON/OFF switch that, according to the instruction card explanation, enables selection of the LOOP (they call it “ring”) position. Wow. The last time we saw this kind of peaking capability on a portable was the SONY ICF-2001 back in the late 1970’s and perhaps the Grundig Satellit 700. Hats off to Raddy for this design!
Controls
The RF919 has a large central concentric tuning outside “shuttle” knob for fast tuning, and a smaller center knob for fine tuning – the center shuttle doubles as a selector with a push function. I am not a fan of encoders that rock back and forth as the outside concentric ring does. At least one user remarked that this feels flimsy. Time will tell whether these hold up in daily use. The keyboard, which is nicely backlit, appears to be quite good. Frequency entry is accomplished by hitting ENT, then the frequency, then ENT again. You can enter in MHz or kHz. There are buttons for VOLUME UP/DOWN, and for TUNE/NEXT, TUNE/PREVIOUS.
One curious thing: if you’re tuning to 22 MHz you can just hit 22 and ENT. But you can’t do that at 23 MHz and above – you have to enter 23.000 and ENT. If you don’t, you get 2.300 MHz. At least that is what I notice on my 919 – perhaps Raddy will be able to clarify why this is so. Another point on controls: the MW/SW1/SW2 switch on the back of the radio is very flimsy and should be improved by Raddy.
Audio
The huge front-firing speaker on the 919 produces superb audio in all tuning ranges. Rated at 20 watts, it rivals the wonderful audio of the Choyong LC90 and combined with the 10 position EQUALIZER makes the 919 even more attractive for someone purchasing it for this level of sound production not to mention a receiver that tunes from LW all the way up to 999 MHz.
Fire up the BLUETOOTH on the 919 and you can not only use it as a speaker linked with your phone, but it will play tracks from the microSD.
ATS/Memories
We have all become accustomed to the convenience of ATS, from the excellent performance on Tecsun radios, and the 919 falls right in line. A scan conducted on FM here in Maryland stored 23 stations and I found sensitivity to be excellent.
Though noise levels were still high from the recent solar activity, a scan on HF yielded a number of stations. It did take quite a long time to complete ATS on shortwave – about 15 minutes, so one hopes this could be improved in future firmware versions. And there is this: when scanning with ATS, the 919 scans the entire HF range rather than just bands. In comparison, ATS on a Tecsun S-8800 takes about 3 minutes, and includes only the main SW bands.
I am not yet sure if the 919 can be made to scan this way, but if not it’s something Raddy should consider. Both displays remain on during ATS. This avoids the need to mess with the display functions while scans are ongoing.
Presets
There are 1600 memory channels on this radio! Once stations are memorized, they can be accessed by hitting the PRESET button on the lower right edge of the main shuttle dials and using the TUNE/NEXT and TUNE/PREV buttons on the keyboard. Note that when going from one present to another the first thing that appears on the display is the CHANNEL number, followed by the frequency. That seems logical but it prevents the user from seeing first exactly what frequency has been memorized without having to wait for the display to shift to the frequency itself.
Bandwidths
The 919 provides bandwidth options not only on shortwave, varying depending on whether one is using AM or LSB/USB, but also in FM – a truly great feature for a portable, and something seen on Malahit SDRs. Bandwidth clarity in SSB is excellent. Maximum bandwidth in AM mode is 6 kHz, similar to portables by Tecsun, with 4 kHz the maximum in SSB. Some users have observed that they would like an 8 kHz AM filter position.
Manual
An extensive manual goes over all of the controls, modes, etc. – the drawback here is that the printing is so small as to make reading it impossible, so better to download the manual in pdf form from the Raddy website and print it out. A bonus is that a three page card guide comes with the radio showing the circuit design and tips for manual antenna tuning and the antenna switching on the back. A very thoughtful addition to the package!
Battery
The 919 continues the trend of radios using 18650 batteries, familiar to professional flashlight users and also seen in Tecsun and other receivers. It takes not one, but two 18650s like the Tecsun H-501. I recommend purchasing a good quality multi-bay battery charger in addition to the ability to charge the radio directly on its USB-C port. Keep in mind that using these radios while charging will create noise, so don’t expect to have the best reception doing it that way.
Recording Capability
Wow! After years of seeing radios with a microSD slot but no recording function, Raddy has gone ahead and done it. You can record any audio to the card and play it. Seems like we could have seen this feature years ago from receiver manufacturers, but we didn’t. Thank you Raddy! That said, I have not yet been able to get recording to work on my unit, using a 64 GB microSD (see below).
Reception Performance
I am very impressed so far with the 919. Sensitivity on HF and AIR appears to be excellent. MW reception is good as well and can be further improved using the antenna tuning feature and the ability to use a loop antenna connected to the receiver. FM reception appears to be quite good. On long wave I was able to hear beacons at levels equal to what I hear on some premium communications receivers.
One observation: when using the RF919 inside my home here in Maryland, I noted what appeared to be some break-in on shortwave from AM or FM signals. I am still investigating this and will report later.
There are many more details to discuss for the RF919. But I need to talk about what I would call the elephant in the room on a relatively short list of CONS, but this is a big one and a bit of a disappointment. The 919 suffers from the issue that is so familiar to us from other portables: MUTING WHILE TUNING. See my video discussing this at:
This is more noticeable when in 1 kHz and 10 Hz increments, and at times of the day when signals are less strong, and seems to be a bit better in the evening when signals improve. But it is there nonetheless.
It’s not the worst soft muting I have ever heard on a portable. It’s certainly survivable. But for those of us who value what I call a continuous listening experience, even the slight muting experienced on the 919 is annoying. It may well be that this can be improved with a firmware update – it’s unclear though whether firmware can be updated via the microSD if new versions were made available on the Raddy website.
Ironically, what soft muting on any receiver does is make the receiver more useful for those of us who over decades of shortwave listening have memorized multiple SW frequencies – using the 919 I prefer to use the keypad to go directly to a frequency rather than put up with the frustrating experience of using the two shuttle knobs specifically because of the soft muting problem.
I should note that there is a harshness one hears from this radio when using the shuttle dials to tune – what I would describe as AGC crashes when going from frequency to frequency. This is nothing new for DSP radios, though some do a better job than others, such as the Tecsun PL-990 and 501 and Data/Sihuadon D-808. It’s clear that when a manufacturer decides to build a radio around these chips, such as the Si4735, there is very little that can be done to smooth out how the chip handles AGC, though I do not claim to be an expert in this area.
Zero Beat Variations
The other issue I observed on the unit sent to me is also familiar – in SSB, the radio isn’t calibrated well enough, so zero beat in LSB or USB vary quite a bit off the actual tuned frequency. While we don’t usually expect DSP portables to be exactly on frequency, this can be annoying as well since in an ideal world we don’t want to have to off-tune from a known frequency of a broadcaster, or amateur operator, to achieve clarity. Tecsun provided a recalibration feature on its portables that enables the user to adjust zero beat. One wishes that other manufacturers would do the same – if the 919 were to have this it would be a welcome addition.
Other Issues
Though the 919 manual states that the receiver accepts up to 256 GB microSD, my first attempt to get a 64 GB card did not succeed. The card is correctly formatted so I am at a loss to determine why this is. Obtaining the Radio-C app was also an adventure – it comes up as an APK file which then installs. Two Bluetooth connections appear, but understanding the process is complicated. I was finally able to get the app working with the radio and continue to experiment with the flexibilities it provides.
Overall, the app provides some great controls over the radio, but the fact that it does not appear on Google Play and has to be downloaded via a QR code may give some users pause. Additionally, temperature appears to display only in Celsius – something I am sure will be corrected in future firmware updates. Also, on the phone app, pressing CB brings the radio to 25 MHz rather than the CB range. When initiating a scan inside one of the SW bands, the scan does not stop at the top of that band. And there does not appear, based on my first tests, to be a way to control SQUELCH from the phone app. Hitting V-UHF on the app screen brings the radio to 20,000 kHz. So, there need to be refinements to the app to clear things up.
Conclusion
So, here’s my summary of the RF919:
Swooping down on us out of the blue, this is an extraordinary entry into the portable category, taking us by surprise with its thoughtful design, seemingly high quality construction, and features that set it apart from other radios on the market today.
Whoever designed the 919 surely had to have some significant experience as a listener because the features included in the receiver move it straight to the top of the list of portable receivers available in 2024.
Comparing the 919 with a receiver such as the Sangean ATS-909X2 there really is no contest. Where coverage is concerned, the 919 blows Tecsun and Sangean offerings out of the water – on this receiver you can listen from LW all the way up to 999 mHz, along with AIR band, weather frequencies, public service, and CB (though as observed by users there is no FM mode reception for CB).
I have not been impressed by other Hanrongda (labeled Raddy/Retekess) offerings. At one point I tried a 747 only to be thoroughly disappointed with its hard-to-see display, terrible SSB, and thin telescopic antenna along with laborious thumb wheel tuning. I was cautious when I saw initial videos of the RF919. But this receiver truly is a major step forward for a portable: superb displays, wide coverage, excellent SSB (aside from the zero beat/calibration issue), wonderful audio, bluetooth capability and phone app control, microSD recording capability – all of these add up to one hell of a radio.
In response to my initial comments on the soft muting and calibration issues, Raddy responded:
“We would like to thank you for bringing two important concerns to our attention: muting during tuning and frequency accuracy. Please rest assured that we are actively discussing these issues with our technical team to gain further insights and potential solutions. We value your input and will keep you updated on any progress made.”
At a price of $269 as this is being written, the RF919 could be a 5 star radio were it not for the aforementioned issues of soft muting while tuning and calibration variation. We can only hope that the designers can address these issues with future firmware updates and possibly make updating something we can do after purchase. The 919 website by the way also offers antennas for the 919 including the Radioddity RD-771 which is described as an upgrade of the popular Nagoya NA-771, and the Radioddity RD-371 “Tri-band” antenna for 144-220-440 mHz.
As of this writing I am not aware of any reviews of the Retekess version of the 919, the TR113, but have to assume that there are no differences. It will be interesting to see how firmware updates occur and again, one would hope that this will be a simple process of being able to download the updates from Raddy/Retekess and be installed on the radio. But so far, there is no sign of this so clarifications from the manufacturer would be appreciated.
It is amazing that in 2024 we still have ANY radios coming to market as advanced as the RF919. This is a receiver that obviously was influenced in design by someone who knows their stuff and included numerous features such as antenna tuning, decent SSB, and the ability to record content. It is frustrating that there have been no advances in chip technology that would allow SSB performance that more closely matches what we had in many classic portables of decades past. But for those who don’t mind things like soft muting while tuning, and can tolerate harsh AGC characteristics of DSP, right now there isn’t anything on the market that matches the RF919 in terms of just wide tuning range and reception tools as well as superb audio.
As for BUY or DON’T BUY, I would edge toward the former with a caution to perfectionists like myself who would be bothered by muting.
If Raddy can fix that issue, and ensure a calibration process that brings LSB and USB closer to zero beat on frequency, and/or include a recalibration function as Tecsun has on its radios, the RF919 would then be an easy YES recommendation. Right now it gets a 4.5 from me, but could easily be a 5.0 if those issues are resolved.

SWLing Post readers have no doubt seen the appearance of the Raddy RF-919, which is manufactured by Hanrongda in China. I have generally not been impressed by some receivers from this company, notably the HRD-747/757 and the reviews seem to support this.
However, from first appearances the RF-919 may be an exception. I am expecting a RF-919 soon, but one of the more recent reviews was by the very popular YouTuber NotaRubicon, and I was surprised to see that according to this review, the RF-919 actually is capable of recording to microSD.
Indeed, when checking the manual available online (Section 8.3) this feature is confirmed. This is an extraordinary development in the portable receiver market and it makes one wonder again why other manufacturers chose not to add this feature. Though we are lacking information about production decisions, it does seem like Tecsun in particular, with its otherwise excellent 990/501 portables, could have implemented recording to microSD.
As of the time I am writing this, there seems to have been surprisingly little discussion by those who have obtained a RF-919 about the recording feature, but I expect there to be more about this when users discover it. As for performance, I hope to have my 919 in hand in coming days and will review it for SWLing. From observing initial user videos, this radio is packed with some impressive features and coverage.
Thank you, Dan! I look forward to checking out the recording function. It would, indeed, be wonderful to finally have a capable portable with proper built-in recording.

The Stampfl “Stressless”
by Dan Robinson
Stampfl based in Switzerland is well known as a manufacturer of excellent antennas, morse keys, and other equipment for amateur radio operators and SWLs. Now, Stampfl is offering what it calls the “Stressless” HF receiver. Housed in a beautiful heavy metal cabinet, one would think that there would be more to this than there is actually is — it’s a very basic receiver made, as the name implies, for those who want a minimum of stress in their HF listening.
Note: All photos have been sourced from Stampfl.
It is intended as an assembly kit, with some minimal soldering required. Heinz Stampfl notes that the VFO and RX board are fully assembled and tested. Total construction time is estimated a 1-2 hours. Star of the show on the Stressless is the large color display which enables changing of colors, tuning step, VFO A/B, attenuation, and memories. The single bandwidth has been well chosen — I had no problems listening to Voz Missionaria in Brazil on 9,665 khz though any stations requiring separation will be a challenge for this receiver since there is no SSB and that one bandwidth. The receiver tunes from 100 kHz to 30 MHz.
One would hope that firmware might be upgradeable, but Stampfl states that this is not possible, which is a bit of a puzzle. The receiver runs on 11-15V DC — the only other thing on the back of the cabinet is the BNC antenna input.
I’ll have more thoughts on the “Stressless” after I complete additional testing. So far, it has appeal as a very simple receiver with high sensitivity and a beautiful front interface. It might be a good choice for beginning SWLs, as many of them as there are out there, but the price/feature ratio is a bit of steep climb against the background of Tecsun portables with multi-bandwidth and SSB capabilities, not to mention the recently released Choyong LC90 which combines good SW, AM, and FM with Internet radio.
The “Stressless” — for those who can afford the price — would be good as an easy-to-use main listening receiver for stations not requiring much DXing skill or tools to separate. These days with the SW bands populated by fewer stations, this receiver might be fun to have around and it is certainly a good way to teach the radio hobby to newcomers.
The “Stressless” I am testing arrived well-packed in a clam-shell style inner box — it was already assembled by Stampfl for which I am grateful. The company also makes the X One Active Dipole antenna, which I am also testing at the moment and will have more on at a later date.
