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.

Panasonic RF-2200 on ShopGoodwill

15 Replies

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN) who shares a link to this National Panasonic RF-2200 on ShopGoodwill.

The bid is currently $78 and ends this evening. You must be registered with ShopGoodwill and have a PayPal account to place a bid.

Note that I’ve had some very good luck in the past with ShopGoodwill, but buying from them is more akin to buying from a flea market than, say, eBay.

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.

I contacted Allan and asked if he could provide any details yet. His reply was almost poetic:

“It’s simple. WBCQ will be constructing one of the biggest, most powerful, most versatile shortwave transmitter and antenna systems in the world. All for free speech radio. Freedom.”

Now that is something I want to see happen! We love WBCQ!

FCC Commissioner pushing for aggressive pirate radio enforcement

13 Replies

Many thanks to an SWLing Post contributor who shares this FCC PDF document: Remarks of FCC Commissioner Michael O’Rielly Before the 2017 Hispanic Radio Conference, Fort Lauderdale, Florida March 28, 2017.

Note O’Rielly’s remarks regarding pirate radio enforcement in the south Florida radio market:

“Many of you may have heard me speak before about pirate radio, a huge problem here in South Florida and one that has a disproportionate impact on the Hispanic radio community. The failure to properly address it highlights a deficiency in the Commission’s enforcement tools and undermines our overall credibility. Today, these squatters are infecting the radio band at the expense of listeners of legitimate radio stations, causing great harm to emergency preparedness within covered areas and undercutting the financial stability of licensed radio stations, your stations.

To that point, I could use your assistance in batting down arguments that pirate radio stations are somehow training grounds for those seeking to enter the field or that these “stations” bring a unique service to primarily minority communities, and therefore should be left alone. Few people actually have your background, experience, and history of serving these important communities, so your voice and words would be a welcome rejoinder to these baseless claims.

On my part, just this morning, I spent some time with the FCC’s Miami Field Office to ring the figurative fire alarm on overall efforts to combat pirate radio stations. Quite frankly, I sought answers on why these stations weren’t already eradicated. In particular, I discussed their recent enforcement actions in this market, what obstacles they face in expediting cases, and what additional authority may be of assistance. I also raised the issue of whether the ability to seize pirate equipment found in common areas could aid their efforts. In addition, we discussed whether our current fines should be increased, and if imposing penalties on those that directly and intentionally facilitate pirate stations could be helpful. It was a very positive meeting, and I walked away with renewed belief that the Miami Team was up to the task. But, they are also on notice that I expect to see this situation addressed quickly and sufficiently.”

Guest Post: National HRO-500 Unboxing and Initial Tests

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post:

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!

Global HF Pirate Weekend: March 30-April 2, 2017

Many thanks to SWLing Post contributor, Andrew Yoder, who writes:

Just a reminder that the next Global HF Weekend is coming up: March 30-April 2, 2017

Finnish DXer Harri Kujala started the weekends (the 1st weekend of April & the 1st weekend of November) about five years ago & I said I’d write about them. The idea was for listeners in faraway areas to be able to hear broadcasts that normally would not be audible (or barely so)–all while promoting cooperation among those in the hobby. In those first GFWs, some transatlantic QSOs were established and stations from Europe & North America were reported in Russia, India, Ukraine, Japan, and other countries.

I’d expect that some stations will post schedules on HFU. I’ll also be tracking the broadcasts and schedules on my blog, so if any stations send schedules to me, I’ll post it, but without the station name: just date, time, frequency. This will be especially handy for those stations who choose to operate outside of Harri’s suggested 19m and 13m frequencies. Given the lack of sunspots and the low solar activity, 9, 11, 13, and 15 MHz might be better choices than 21 MHz.

Here’s the rest of the general info:

March 30-April 2, 2017
General frequency ranges:
15010-15100 kHz
21455-21550 kHz

Basic schedule:
European morning, 0800-1200 UTC from Europe to Asia/Japan/Oceania.
European afternoon, 1200-1600 UTC from Europe to North America and vice versa.
European night, 2200-2400 UTC from North America to Asia/Oceania.

Of course, these are general frequency ranges where pirates have broadcast during prior Global HF Pirate weekends. Some stations will surely operate on frequencies and times outside of these ranges. These will be updated on HF Underground (https://www.hfunderground.com/) and on the Hobby Broadcasting (http://hobbybroadcasting.blogspot.com/) blog as it happens.
