Pirate Radio Recordings: Wolverine Radio

Wolverine Radio eQSL–one of two SSTV images decoded near the end of the broadcast

For your listening pleasure: 2 hours and 46 minutes of pirate radio station, Wolverine Radio–recorded Sunday, February 17, 2013 around 2:40 UTC.

Wolverine was broadcasting on 6.925 MHz in the upper side band. Typical of Wolverine, lots of music variety which spans the decades, and no commentary other than station ID throughout.

I decoded two of the SSTV images Wolverine transmitted; the Canadian flag (see right) and this one. You can easily decode these live, or via the recording below. Per Ragnar’s suggestion, I now use MMSTV to decode SSTV images.

Daniel shares recent QSLs

I have been enjoying some shortwave broadcasts recently and received some nice QSL cards. Wanted to share the cards and some station information.

Deutsche Welle – copied broadcast on 15,275 KHz – Jan 20 , 2013 at 1930 UTC

China Radio International – copied broadcast on 9,580 & 6,020 KHz – Dec 29 & 31 , 2012 at 0130 UTC

VOA – Africa service –
They sent not only a QSL but a beautiful 2013 calendar.

Daniel addeded:

Shortwave listening was my first step to becoming an amateur [radio operator]. First receiver was a Lafayette HE – 10 with a Q mulitplier I built. Now using a WinRadio 313 – things have really changed.

Shortwave listening was also my first step to becoming a ham radio operator. The Lafayette HE-10 is a beautiful little 9 tube radio. I love the split dials on the front–much like the venerable Hallicrafters S-38.

VOA’s Radiogram adds digital content to AM broadcasts

Leave a reply

VOA Radiogram is a new Voice of America program experimenting with digital text and images via AM shortwave broadcasting. One might say this is the crossover point between classic shortwave and current technology. It’s fun and fascinating stuff, and also has real utility.

If you’ve been an SWLing Post reader for very long, you’ll be familiar with the digital messages, otherwise known as radiograms, included in broadcasts from The Mighty KBC and, earlier, from WBCQ. We’ve also offered a small primer on decoding.

In the near future, Dr. Kim Elliott’s digital radiograms will be broadcast through VOA via the Edward R. Murrow Transmission Station in Greenville, NC.

The new VOA Radiogram website contains time and frequencies and all of the information you’ll need to decode VOA radiograms.

Incidentally, Kim Elliott and I will be presenting on the topic of VOA Radiograms and digital modes at the 2013 NASWA Winter SWL Fest. If you’re interested, it’s not too late to register! Meanwhile, stay tuned for more information about radiograms.

Trevor Baylis in the Vintage Vault

Leave a reply

Earlier this week, I posted an article about wind-up (clockwork) radio inventor, Trevor Baylis.

I recently discovered a 1995 episode of RNW’s Media Network, which featured Baylis–and the clockwork radio–in the context of inventions that would carry us beyond the new millenium:

Remember Trevor Baylis and the wind-up radio? I organised a conference for Radio Netherlands at the International Broadcasting Convention IBC between September 11-14th 1995. We decided to celebrate the fact that we were 5 years away from a new Millennium by looking at the technologies that would carry us forward. That included a look at different codings for DAB, a reality check on radio by Sri Lankan broadcaster Victor Goonetilleke and a special performance about the Clockwork Radio from Trevor Baylis, the British inventor who turned up in Amsterdam and charmed the audience with his frank, funny and brilliant introduction to the concept of wind-up radios. A few weeks after the conference we produced a special CD for those who took part. This is a copy for those who missed it. It’s double the length of a normal Media Network, just over an hour.

You can download this archive episode of Media Network on the Vintage Vault website.

By the way, Jonathan Mark’s Media Network Vintage Vault has many, many audio treasures from the radio past. Certainly worth bookmarking!

History of WWV and the NIST Time Stations

Many readers know that I’m a bit of a WWV geek, so you can imagine how happy I was when my buddy, Mike, and the Southgate ARC made me aware of this 152 page history of the NIST time station family. At first glance, this looks to be an authoritative and thorough history indeed.

I have already sent this to my Kindle Fire and look forward to reading it (at least, starting it) tonight. Click here to download the NIST time station history as a PDF.

Incidentally, if you have an affinity for the NIST time stations, be sure to check out my previous post on Myke’s audio history of WWV, “At The Tone.”

From the Dutch website (my translation):

The disappearance of a number of tasks of Radio Netherlands Worldwide means some of the technical equipment is now available for sale. This includes a fully equipped Network Operations Centre with a network matrix of NTP, a complete Studer system with four presentation cells and and a master console, six Studer ‘WPM’s’, all of the type ‘On-Air’ 3000 or ‘On-Air’ 2500. In addition, many peripherals are offered, including Airtools voice processors.

Massive sunspots appear, solar flares could follow

(Source: Christian Science Monitor)

A colossal sunspot on the surface of the sun is large enough to swallow six Earths whole, and could trigger solar flares this week, NASA scientists say.

The giant sunspot was captured on camera by NASA’s Solar Dynamics Observatory as it swelled to enormous proportions over the 48 hours spanning Tuesday and Wednesday (Feb. 19 and 20).[…]

“It has grown to over six Earth diameters across, but its full extent is hard to judge since the spot lies on a sphere, not a flat disk,” wrote NASA spokeswomanKaren Fox, of the agency’s Goddard Space Flight Center in Greenbelt, Md., in an image description.

[S]ome of the intense magnetic fields in the sunspot region are pointing in opposite directions, making it ripe for solar activity.

“This is a fairly unstable configuration that scientists know can lead to eruptions of radiation on the sun called solar flares,” Fox explained.

Propagation in the higher portions of the HF band could be very interesting over the course of the next few days. If a solar flare erupts, however, it could make shortwave listening quite difficult.

Thanks for the tip, Bill!
