Tripp Lite dual ferrite USB cables

I found this tip from Lorne Waters on the SDRplay Facebook page:

I was having a lot of trouble with local noise and not getting really good signal spikes. Well I took a chance after reading many articles on using better USB cables. The picture below is what I purchased from amazon. It’s a USB with dual ferrite cores mounted at each end. Well this did wonders for me. It’s like less than 10 bucks. Well worth it. Try it for yourself. Using with SDRplay RSP1a.

Lorne has a good point. All of my SDR USB cables have at least one in-line ferrite choke. Cables with dual chokes like the Tripp Lite are pretty rare. Note that this USB cable fits SDRs (like SDRplay models) with a USB-B port. I’ve had a difficult time in the past finding dual ferrite choke USB-A to Mini or Micro USB ports. In those cases, I often employ these inexpensive snap-on ferrite chokes.

Glenn Hauser’s World of Radio extra program from September 08, 1984

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who writes:

Rosebud Reservation location in South Dakota

One of Glenn Hauser’s more interesting “extra” programs to me over the years was his radio 1981 summer vacation recordings to South Dakota (near the Nebraska border).

Attached is the entire WRNO recording of that program (which aired on Sep 8, 1984). This was before he “air numbered” the programs.

Amazing, Dave! Thank you for sharing this recording.

Radio World: “Historic Woofferton Boasts a Modern Twist”

WOOFFERTON, England — Nestled in the beautiful Shropshire countryside, just a few miles from England’s border with Wales, is the tiny village of Woofferton. That name is synonymous with shortwave radio for millions of listeners around the world as just a short distance from the village itself, lays the United Kingdom’s last remaining public service shortwave transmitting station.

Now owned and operated by Encompass Digital Media, Woofferton recently celebrated its 75th birthday. Built in 1943, the station has a fascinating history; originally designed to bolster the BBC’s General Overseas Service (now the World Service) during the latter years of World War II, it was later partly funded by the United States and was used extensively by the Voice of America to broadcast into Eastern Europe and the former Soviet Union during the cold war years. Today, Woofferton transmits programs for the BBC and a number of other international broadcasters, reaching audiences across Europe, North Africa and the Middle East.

[…]There are 10 high-power HF transmitters at Woofferton. They range from Marconi senders of various vintages, including two BD272 250 kW units that date back to the 1960s, to the more recent 300 kW B6124 solid-state transmitters, and four of the most modern RIZ 250K01 wideband systems, which are also capable of operating in Digital Radio Mondiale (DRM) mode. In fact, the BBC’s daily DRM transmission for Europe is broadcast from here.[…]

Initial impressions of the ALT-512 QRP transceiver

So the ALT-512 QRP SDR transceiver has landed at SWLing Post HQ. This little rig is on loan from Aerial-51 and I’ll be spending the next month or so putting it through the paces.

I can already tell that the ALT-512 has some strong points:

  • It’s incredibly portable and easy to take to the field, providing you have a battery and resonant antenna (or external ATU).
  • The color backlit display is quite readable at any angle despite being rather information-dense.
  • I really like the waterfall display. It’s large enough to be quite useful.
  • The ALT-512 can connect directly to your computer for digital modes like FT-8. No external sound card needed.
  • The menu system contains a wide array of features and options for granular tweaks and modifications.
  • The ALT-512 includes the European 4 meter band.
  • Although I prefer using headphones with small radios, the ALT-512’s small internal speaker does a fine job.
  • Rob Sherwood tested the ALT-512 (indeed, this very unit) recently and added it to his receiver test data. It performed quite well especially considering the price.

Any negatives so far?  Nothing major:

  • No internal ATU or battery options. At this price point (799 EUR), I wouldn’t expect either of these.
  • The ALT-512 is not general coverage. This is a negative for those of us who like SWLing, but a positive for ham radio use as the ALT-512 sports band-specific bandpass filters to reject out-of-band strong stations. You can tune to some stations above the 40M band and also the full mediumwave band and below (down to 100 kHz), although I wouldn’t expect stellar performance in those regions.

So far, I’m very pleased with the ALT-512’s performance.

Next, I’ll be taking it to the field and see how easily I can activate a few POTA (Parks On The Air) sites! Stay tuned!

Giuseppe captures LRA36 special on the coast of Italy with a portable receiver

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who writes:

Giuseppe Morlè

I’m Giuseppe Morlè from Formia, Italy, on the Tyrrhenian Sea … I had the pleasure of listening to the transmission of LRA36 Base Esperanza Antartida Argentina on 15,476 MHz on 21 September 2019 at 14.01 UTC.

I used a 25 meter wire, on the ground, with salt water resistance in a SSW direction that I have been using for years … similar to a “beverage on salt ground”.

I made the following video of the broadcast on my YouTube channel:

Wow! Giuseppe I am most impressed with your reception of the elusive LRA36. No doubt, this is testament to the power of combining a low noise environment, a capable shortwave receiver, and a longwire on a salt ground.

Dan records the LRA36 special broadcast

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

As the DX/SWL community knows, LRA-36 Radio Arcangel San Gabriel in Antarctica Argentina put on a special broadcast on September 21st for listeners around the world. This had some pre-publicity via an announcement from the station, so chances are many people heard it.

My listening began at around 1253 UTC when I was surprised to find the broadcast already in progress, though the time was originally set for 1300-1415 UTC. Because the Paradinho, Brazil Kiwi site was full I tuned to one of two Iceland-based SDRs at 1253 to find an Argentine song often used by the station in progress, then sign on announcements, including what sounded like English greetings to listeners, followed by a program that consisted mostly of two female announcers in conversation, punctuated by occasional drop-ins by a male announcer with ID’s and sending “abrazos” (embraces/hugs) to listeners.

At 1400 UTC, there was a period of CW ID followed by some more discussion until about 1415 when they went into straight music. Programming actually lasted through 1430 when I tuned away — the transmitter was not on when I checked at noon EDT, but the station said they intended to repeat the special program later in the day. Here is video of the beginning of the program as heard at 1253 UTC, as well as the CW ID at 1400.

Excellent! Thank you, Dan for sharing your recording.

I also made a recording remotely via my home SDR while travelling this weekend. I’ll review the recording the coming days.
