Many thanks to a number of Post contributors who’ve shared a link to links to bcloyaji’s YouTube Channel where a few videos of the Icom IC-R8600 have been posted. (Thank you for your patience, as well, as I’ve been traveling and way behind on posting this!)
I’ve embedded a few videos below, but I encourage you to also check out bcloyaji’s YouTube Channel for more:
I’m looking forward to checking out the IC-R8600 at the 2017 Dayton Hamvention and even potentially reviewing it here on the SWLing Post at some point.
Any Post readers plan to purchase the IC-R8600?
Though we have no US pricing yet, I’ve been checking with Universal Radio regularly for any news.

The IC-7610 (Source: Icom UK)
Icom Inc. has released more details about the launch of the IC-7610 HF/50MHz SDR Transceiver and its target price. Icom plans to release this high performance HF SDR transceiver around late May with the product being rolled out across the globe in the following months. We expect that the IC-7610 should be available in the UK early Summer with a suggested retail target price of £2,999.99 ex.VAT. Please note that this target price and UK availability may be subject to change.
We expect demand to be huge for this product. Indeed many back orders are already on our system. So if you want to be one of the first customers in the UK to own one of these eagerly awaited radios, please contact your Icom Amateur radio dealer who will be able to put you in their order books.
More about the IC-7610 HF/50 MHz 100 W SDR transceiver
Following on from the technology incorporated into the IC-7300, the IC-7610 adopts the same RF direct sampling system for signal processing. By converting the analogue signal directly to a digital signal and processing it within the FPGA (Field Programmable Gate Array), it provides improved transmission phase noise and excellent RMDR of 105 dB (at 1 kHz detuning).
The IC-7610 will have two independent receivers, enabling simultaneous reception of two frequencies in different bands/different modes.
The IC-7610 will also feature high-speed, high-resolution performance. The real-time spectrum scope supports different bands and a dual display that can monitor different modes. It will also have a waterfall display function that displays received signals in time sequence. The DIGI-SEL unit will be available to both the main side and the sub side of the receiver. In addition, the IC-7610 adopts a large 7-inch full-colour touch screen panel.
Main features include:
• Further evolved RF direct sampling method.
• Excellent RMDR: 105 dB realized.
• Dual watch function can receive simultaneously in different bands and different modes.
• DIGI-SEL unit that eliminates excessively strong signals is installed in the main and sub of the receiving section.
• High-speed real-time spectrum scope and waterfall display function.
• 7-inch full-colour touch panel, outstanding operation and visibility
As mentioned earlier, demand is going to be enormous for this model, so get into contact with your authorised Icom Amateur radio dealer today.
Almost always items are sold as-is, no returns, have mediocre low resolution product photos, and are not properly tested. In the case of this RF-2200, it appears the Goodwill employee turned on the radio and tuned the FM band which worked fine.
If you’re willing to take the risk, though, you can often snag great deals on ShopGoodwill.

HRO-500 Unboxing and Initial Tests
by Dan Robinson
It is amazing that in these days of waning shortwave broadcast activity, there are still those occasional time capsules — radios that appear on the used market via Ebay or private sales that are new in the box or close to it. Think of it — after 50 or 60 years, these fine examples of radio history can still be found, complete with their original boxes, shipping crates, manuals and accessories.
We have seen a number of these in recent years. Several years ago, a Panasonic RF-9000, one of the Holy Grails of radio collecting, appeared on Ebay, in new opened box condition. As rare as that was, it’s even rarer to find tube or solid state communications receivers from the 1950’s and 1960’s. Such is the case with National HRO-500s, which were considered high level receivers when they came on to the market in the mid-1960’s.
In 2016, a seller in California advertised a great rarity — a HRO-500 that he said he purchased in 1967, complete with its original shipping crate.
It was said to be in new/unopened condition, which of course raises concerns about the unit itself since it has never been used since leaving the factory. While that radio apparently sold (the asking price was $2500), I was astounded to recently see another HRO-500. It was not in New/Unopened condition, but the closest one comes to it. Among a collection purchased by the seller, the radio was in its original crate, inside of which was the original box with the original National Radio Co fabric cover, with original strips of fiberglass insulation. The manual is still in its plastic wrap.
I decided to do a video for SWLing Post readers, and provide some still shots, as this time capsule of radio history was opened (this was likely only the 2nd or 3rd time it was opened since leaving the factory, the last time by the seller for photography for the Ebay ad.
The good news — many HRO-500s on the used market exhibit failure of the PLL lock circuit. While the PLL lock light on this particular radio does not light up, its PLL does operate on every band. This radio arrived with one metal cap for the MODE knob missing, so I’ll be searching for a spare. And the dial calibration clutch knob appears to be frozen, another minor issue that does not impact operation of the radio.
All in all, this was a fantastic find and I hope SWLing Post readers enjoy the video and stills:
Thanks for sharing your notes, photos and video, Dan!
The National HRO-500 is a gorgeous radio and it looks like you’ve got a prime specimen. I’m so impressed it came with the original wooden crate, exterior box and radio box! Amazing.
We’re looking forward to your assessment of the HRO-500 once you’ve have it on the air a while.
SWLing Post readers: In March, I had the good fortune of visiting Dan Robinson’s home and taking a tour of his impressive radio collection. I took a number of photos with Dan’s permission. I’ve been incredibly busy as of late, but as soon as catch my breath after travels, I’ll post the photo tour. I’ll also post photos from our tour of the NSA museum in Fort Meade, MD. Stay tuned!
Many thanks to SWLing Post contributor, David Korchin (K2WNW), for sharing a link to this Braun T-1000 on eBay.
With two days left on the auction and already 73 bids, I believe David is correct in assuming this radio might fetch upward of 900 Euro. Braun models certainly tend to fetch premium prices. The T-1000 is possibly my favorite Braun portable and I certainly wish I had one. I love Dieter Rams’ designs.
Note that shipping seems very modest at 6 Euro worldwide via DHL. I would check on that pricing prior to bidding if outside of Europe. This seller has a 100% rating with over 400 transactions on eBay. Again, thanks for the tip, David!
Recently, Tecsun announced and released onto the market the new S-8800 receiver. Thomas Witherspoon has indicated that sensitivity, selectivity and audio fidelity are very good for this new unit.
BUT…..in his post on February 12, 2017, entitled Tecsun S-8800 Update, Thomas discovered that his new S-8800 has a serious fault, one that could potentially drive radio enthusiasts mad! In tuning around the dial, he found the radio has many “birdies”. In the same post, he notes that Bertrand Stehle F6GYY also found birdies on 4 spots in the mediumwave band and 63 frequencies across the entire shortwave spectrum. Not good!
In reading the comments that followed Thomas’ post, I noted that a few writers seemed a little confused about what a birdie is and how it differs from radio frequency interference. Hopefully, the following explanation will shed some light.
The term “birdie” is, I guess, derived from the type of sounds that are emitted from a receiver having this problem. It can take on a variety of forms, like a squealing or whistling sound, or perhaps a warbling sound, or a hash noise, or indeed, even a silent carrier. In a particular radio, a birdie could appear on one or many frequencies across longwave, shortwave, mediumwave or into the VHF spectrum. And it will usually be permanently there on the same frequencies every time.
Occasionally, you will find birdies smack bang on the very frequencies where you might want to do some listening. But, unfortunately you can’t really do anything to get rid of these nuisances because the design faults are in the the receiver itself. You can test to see if what you are listening to is a birdie by simply disconnecting the antenna. If the squealing/whistling/warbling/hash/silent carrier is still there without any antenna, then it’s a birdie – an internally generated carrier by the receiver’s own circuitry.
