Photos from the 2019 Berryville Hamfest

Many thanks to SWLing Post contributor, Dan Robinson, who shares this excellent photo gallery from the Berryville Hamfest. Dan notes:

You will notice one photo in particular — of a rare Skanti R-8001 and a Telfunken E1500.

The Skanti, which went for only $600, is now comfortably sitting in my radio shack!

Wow! What an impressive collection of radios at this flea market. Looks like Berryville is worth the trip for anyone with an interest in vintage radio.

Thank you so much for sharing these pics, Dan!

Frontier Silicon’s favorites feature is back

3 Replies

Many thanks to SWLing Post contributor, John Figliozzi, who discovered that the favorites feature is back on his Frontier Silicon-based WiFi radio and notes:

Check out the screen on your Como Solo and follow the instructions. Full features appear to be back! Wrote to Peter Skiera at Como and he said it wasn’t planned to go live until [today], but it showed up on my screen [Saturday]. Seems to work smoothly and flawlessly.

Brilliant news! Thank you for sharing, John. I’m happy to see that Frontier Silicon is getting back on its feet after dropping the vTuner backbone that powered its aggregator for so many years. Several others have commenting with this good news. This is certainly a positive sign.

Swiss Shortwave Merry-Go-Round Founder Bob Thomann (HB9GX) is Silent Key

5 Replies

Readers old enough to remember listening to SBC/Swiss Radio International will, no doubt, remember Bob Thomann. I just received the following note from Bob Zanotti:

Dear Friends and Broadcasting Colleagues,

[O]ur old friend and colleague, Bob Thomann HB9GX, passed away peacefully on Saturday afternoon 3 August local time. He would have been 91 in September.

[…]Bob Thomann was the founder of the Swiss Shortwave Merry-Go-Round on
SBC/Swiss Radio International back in the 50’s. He and I were teamed up in 1970, when I joined SRI. We co-presented the technical mailbag show,
which became know as “The Two Bobs” for 24 years between 1970 and the show’s ending in June 1994. Bob never missed a show, even when we had to do a telephone hookup when he was hospitalized back in the 80’s.

This is the end of “The Two Bobs” Era and an era in shortwave broadcasting in general. But I’m happy to say that the show lives on at www.switzerlandinsound.com, where it has its own section. All that survived from the “Merry-Go-Round” is there, including new material we produced especially for the website. And this will remain as a memorial to Bob Thomann and his contribution to shortwave broadcasting as long as I’m still around.

Bob Thomann was my friend, colleague and fellow ham operator for many years. I will always fondly remember those golden days we shared together. Long live those memories.

73,
Bob Zanotti

Bob, we’re so sorry for the loss of your dear friend and colleague. His memory certainly lives on.

Backlit keys, headlamps, and radio listening in the dark…

17 Replies

The Digitech AR-1780 has a very tactile button/key arrangement, but it is not backlit.

No less than two readers have contacted me this past week asking if I know of a shortwave portable that has backlit keys. Both of these guys, of course, are simply looking for a digital radio that’s a little easier to use at night in the dark.

Backlit keys would certainly make a lot of sense.

I’m going to look through my inventory of portables when I’m back home, but at the moment I’m drawing a blank. I can’t think of a single portable that has backlit keys, but I’m sure there are some out there in the wild. Can someone jog my memory–?

Readers: Please take a moment to comment with the make/model of any shortwave portables that have backlit keys! It would be nice to have a list to reference.

The indispensable headlamp…

I do quite a bit of portable shortwave listening in the dark. I especially like sitting on my porch at night to catch a little DX, pirate radio activity, or simply listen to one of my favorite broadcasters. Even though I have much more capable radios in the shack–ones that are connected to large outdoor antennas–I love the simplicity of a potable for band scanning. Portables are especially fun for night time mediumwave DXing.

I also live in a relatively rural and remote area and one of the things I love about living here is the lack of light pollution at night. This also means that if I want to see when walking outside–and avoid walking into a visiting black bear (true story)–I’ll need some sort of flashlight/torch.

I’ve been made fun of before for carrying so many flashlights around (Mark Fahey, I’m looking at you–!), but frankly, these lighting tools have saved my bacon more than once.

I have an array of high-power portable flashlights, but the one I use the most is actually a headlamp. By using a headlamp, both hands are free to do work–especially helpful while tuning a radio.

These days, I never leave home without a headlamp. I always have one packed in my backpack, EDC bag, or luggage. Headlamps used to be heavy, expensive and sometimes used odd battery types. Today, headlamp prices are very reasonable, they’re lightweight, USB rechargeable, and they’ve become incredibly versatile.

The Nitecore NU25

My favorite for performance vs. price is the Nitecore NU25. I’ve had this particular model for three months. The price is approximately $35 depending on the color you choose. It’s very lightweight and, best of all, USB-rechargeable.

The battery life is excellent; I use it all the time, yet I think I’ve only recharged it twice just to make sure the battery was topped-off.

I also like the Nitecore NU25 because it has an array of lighting options:

A primary light with up to 360 lumens (4 lighting levels)
A 20 lumen high CRI LED which better replicates soft sunlight
A 13 lumen red LED with two light levels and a flashing option

For radio listening, I often use the the CRI LED, or the brighter red LED setting which preserves my night vision.

If I’m reading a book, then I use the CRI LED which casts a very wide, comfortable, full spectrum light.

For walking, hiking, or doing DIY projects in the attic/basement, I use the main headlamp light which has a tighter beam and can cast light a significant distance.

The Nitecore NU25 is very compact and easy to take on my one-bag travels. I feel some sense of comfort knowing that if my hotel experiences a loss of power (again, true story) I’ve got a capable, multi-function light in my EDC pack.

Click here to check out the Nitecore NU25 on Amazon (affiliate link supports the SWLing Post).

There are actually a number of excellent headlamps on the market. Personally, I look for ones that are affordable, rechargeable, lightweight, compact, and have at least an auxiliary red LED (which I find most useful for astronomy). I considered the PETZL Bindi because it’s incredibly lightweight and a friend recommended it, but it lacks lighting options and is pricier than the Nitecore NU25. The PETZL Bindi is an excellent option for runners, however. The PETZL ACTIK CORE also came highly recommended, but it costs almost twice what I paid for the Nitecore NU25.

Of course, if you just want a simple, basic headlamp for SWLing, you can get away with this $15 Foxelli headlamp. It does almost everything the Nitecore does at less than half the cost. In fact, I’m tempted to buy one of these to keep in my truck.

Any headlamp/flashlight recommendations?

I know for a fact that there are some dedicated flashlight/torch enthusiasts in our community who are active members of the excellent Candlepower Forums. I’ve tapped into their knowledge more than once when purchasing flashlights. I hope they’ll chime in and comment with their recommendations!

1963 Film features the Rugby Radio Station

1 Reply

(Source: Southgate ARC)

Rugby was not a conventional radio station but a communications hub transmitting radio telephony, including the now obsolete telex service that later gave way to fax

The 800 ft high masts had been a landmark since the 1920s and, as reporter David Rees finds out, maintaining them is tough, particularly during the coldest winter of the twentieth century. As one rigger says, “The wind doesn’t have time to go round you, it goes straight through you.”

Eighty years of broadcasting history came to an end when Rugby Radio Station was closed in 2007.

Hackaday looks back at the venerable RTL-SDR

2 Replies

Many thanks to SWLing Post contributor, Paul Evans (W4/VP9KF), who shares the following article from Hackaday:

Before swearing my fealty to the Jolly Wrencher, I wrote for several other sites, creating more or less the same sort of content I do now. In fact, the topical overlap was enough that occasionally those articles would get picked up here on Hackaday. One of those articles, which graced the pages of this site a little more than seven years ago, was Getting Started with RTL-SDR. The original linked article has long since disappeared, and the site it was hosted on is now apparently dedicated to Nintendo games, but you can probably get the gist of what it was about from the title alone.

When I wrote that article in 2012, the RTL-SDR project and its community were still in their infancy. It took some real digging to find out which TV tuners based on the Realtek RTL2832U were supported, what adapters you needed to connect more capable antennas, and how to compile all the software necessary to get them listening outside of their advertised frequency range. It wasn’t exactly the most user-friendly experience, and when it was all said and done, you were left largely to your own devices. If you didn’t know how to create your own receivers in GNU Radio, there wasn’t a whole lot you could do other than eavesdrop on hams or tune into local FM broadcasts.

Nearly a decade later, things have changed dramatically. The RTL-SDR hardware and software has itself improved enormously, but perhaps more importantly, the success of the project has kicked off something of a revolution in the software defined radio (SDR) world. Prior to 2012, SDRs were certainly not unobtainable, but they were considerably more expensive. Back then, the most comparable device on the market would have been the FUNcube dongle, a nearly $200 USD receiver that was actually designed for receiving data from CubeSats. Anything cheaper than that was likely to be a kit, and often operated within a narrower range of frequencies.

Today, we would argue that an RTL-SDR receiver is a must-have tool.[…]

Of course, for all things RTL-SDR and beyond, I highly recommend bookmarking RTL-SDR.com.

The RTL-SDR.com blog also manufactures my favorite flavor of the RTL-SDR dongle along with a nice bundle of antennas. Click here to check it out on Amazon.com (this affiliate link supports the SWLing Post).

The SDRplay RSP1 just turned five years old

3 Replies

Yesterday, @SDRplay noted on Twitter:

It’s 5 years ago today we sold the very first blue and white RSP to someone in Sweden – many thanks to all our customers over the 5 years

Perhaps it’s just because I’m getting older, but it’s hard to believe it’s been five years!

The little RSP1 really disrupted the SDR world. Up to 2014, there were few sub $150 SDRs that included HF reception natively. There were even fewer sub $150 SDRs that I would consider “enthusiast grade”–those that were sensitive, selective, and not prone to overload.

When I initially tested the RSP1 it pretty much blew my mind. I was so impressed by the performance for the price point.

Looking back at my original review, I see that I had a long list of “pros” and only three “cons.” In fact, two of the three “cons” I listed are no longer valid (multi-channel recordings are now an option and SDRplay has their own OEM application, SDRuno).

SDRplay has demonstrated iterative agility with each new product offering and built an impressive community in five years. They have also maintained their position as a price leader even though their products are all designed and manufactured in the UK.

Congratulations, SDRplay! Happy Birthday to the RSP1! Click here to check out SDRplay.
