Looking back at the The 26th Annual SWL Winterfest

I originally wrote this article for the July 2013 issue of Monitoring Times Magazine. I hope you enjoy:

Every year, I look forward to the only event I know that brings together both my avid interest in radio and my loyal radio-listening friends: the Winter SWL Fest. This is the one place where, among the 100-plus attendees, you can talk freely about all aspects of the shortwave hobby without any need of explanation as to why you find radio so fascinating. As a result, over the course of the five years I’ve attended the ‘Fest, it has begun to feel less like a technical hobbyists convention and more like a (most enjoyable) family reunion.

Larry Will of Area 51 presents an audio and video history of WBCQ

This year, and for the third year in a row, the Winterfest was held at the DoubleTree Inn and Suites in Plymouth Meeting, Pennsylvania, just outside Philadelphia. The venue is spacious and comfortable, and all presentations are held within its generous environs.

Moreover, we enjoyed presentations on a number of interesting and unique topics that were, by no means, limited just to shortwave radio. A few topics catered to individuals who simply enjoy DXing in any forms. Here’s a sampling:

  • Ed Mauger started the forums off on a light note with a fun discussion on how to increase the size of your radio collection through online auctions and flea markets. His forum drew a large crowd–and many questions.
  • Larry Wills, of Area 51 fame, held the second forum, which was a look back through the WBCQ video and audio archives. During the course of his presentation, Larry covered many of the nuances of WBCQ’s history, including some of the people and circumstances surrounding the birth of this remarkable free speech radio station. Trust me when I say that it was not difficult to keep the audience engaged on this topic: WBCQ listeners are well aware of the variety of shows, not to mention the on-air personalities, that station features. Larry’s presentation put these in context. By the conclusion, I felt I had visited the WBCQ transmitter site in Monticello, Maine, myself.
  • Mario Filippi’s forum, DXing with a Dish, explained the hobby of TV DXing–in a sense, via Free-To-Air (FTA) satellite television and radio. His presentation was comprehensive, covering everything from the components of a home system to the free content currently available–and speaking of satellites, Dave Marthouse’s forum, Sounds from Space: Monitoring and Tracking Satellites Using HF, taught us how to monitor various orbiting satellites that can be heard throughout the spectrum. He also demystified the process, showing us how easy and inexpensive hunting space sounds can be.
  • Skip Arey presented a topic many ham radio operators can appreciate, namely, QRP: How Low Can You Go? Skip’s presentation made for an interesting juxtaposition to the kilowatt shortwave broadcasting world when he revealed how to communicate across the planet on 5 watts or less–!
  • Jef Eichner once again presented on the topic of loop antennas. As more and more of us are bombarded with radio interference (RFI) from consumer electronics, loop antennas make for an affordable means to an antenna that can help you cope with noise. Though this topic can get pretty technical, Jef kept the discussion at a level most anyone could understand. He even brought his own homemade loop for demonstration.
  • Dr. Kim Andrew Elliott and yours truly presented a forum on Digital Text via Shortwave Broadcast. We demonstrated how incredibly effective and simple it is to broadcast digital text modes used by radio amateurs (e.g., PSK31) on analog amplitude-modulated shortwave broadcasts. These modes can be decoded by anyone with a basic shortwave radio and and personal computer or smartphone. We proved that even when the human voice is difficult to comprehend because of poor shortwave reception conditions, digital text can be received with nearly 100% accuracy. The applications for this technology are numerous, but the service can be invaluable when the internet is disrupted by disasters (or by dictators). [Update: since publishing this article, Kim Elliott’s VOA Radiogram has enjoyed great success on the air.]
David Goren hosts the annual Shortwave Shindig

Of course, there are a few mainstays in the Winterfest forum line-up, forums we’ve come to anticipate:

  • The annual “Scanner Scum” forum, which this year focused on scanner antennas that are effective and affordable. The presenters also explained the differences in the numerous types of rechargeable batteries on the market; as a result, many of us now have a better understanding of discharge curves and their effect on radios.
  • The Annual Pirate Forum always attracts a large crowd. This year, George Zeller and a panel of pirate broadcast enthusiasts took the stage to introduce newcomers to the pirate radio listening hobby and review the pirate radio year. This year, Free Radio Weekly editor Chris Lobdell and the pirate station Captain Morgan were inducted into the Pirate Radio Hall of Fame.
  • David Goren (our resident Shortwaveologist) held his 10th Annual Shortwave Shindig, an evening celebrating the unique sonic properties of our favorite international medium. David showcased a number of his own shortwave audio productions and numerous intriguing recordings. Saul Brady played radio-themed folk music, and the talented Martin Peck quizzed the audience with his woodwind renditions of dozens of interval signals past and present. Martin even took requests from the audience and played interval signals on demand…Where else could you hear this stuff, but at the Shortwave Shindig of the Winter SWL Fest?

Of course, there are also opportunities to buy and trade equipment at the Friday night swap meet–and if you’re lucky, you might just win a treasure in the silent auction (where all proceeds go to charity) or in the dinner banquet raffle. Indeed, since I’ve been going to the ‘Fest, I’ve been most impressed with the number and quality of items in the raffle. The odds are good, and this year yours truly even won a few items. This year’s grand prize? The newly introduced CommRadio CR-1 tabletop SDR.

Winterfest-SocialAs interesting and varied as the forums are, and as rewarding as the silent auction and dinner/raffle can be, I believe many of the ‘Festers would agree that one of the strongest attractions is the yearly opportunity to socialize and connect with all of radio’s kindred. At times radio listening can feel like a very solitary hobby, as voices drift in and out of the ether; perhaps the beauty of the Winter SWL Fest is that it brings everyone together face-to-face to socialize and to theorize on the ever-widening scope of radio communications and broadcasting.

Many thanks to Festmeisters John Figliozzi and Richard Cuff

In short, the SWLing Winterfest is always a unique and dynamic event–but don’t take my word for it. Next year, you might just want to check it out for yourself! It will be held February 28-March 1st, 2014 somewhere in the greater Philadelphia area.

The view from the Voice of America

VOA-Roof - DC

Click to enlarge

Today, I visited the Voice of America in Washington, DC and had lunch with my good friend and fellow shortwave radio enthusiast, Dr. Kim Andrew Elliott, creator of the VOA Radiogram. Besides giving me an update on the success of the VOA Radiogram broadcasts, Kim took me to the roof of the VOA building on Independence Avenue, so that I could check out the antenna farm of the VOA Ham Radio Club (K3VOA). I took several photos on my DSLR camera and will post them here upon my return.

While up there, I couldn’t help but note this incredible view of the Capitol Building; I snapped this quick shot–which can’t do it justice–with my iPhone.

Myke maps his radio recordings

MykeOur friend, Myke Dodge Weiskopf, writes with an update:

“I went through all 600+ recordings of mine and generated a highly accurate Google Earth KML file pinpointing all the transmitters (along with reception details). Lots of fun for SWL types to fly around and look at antenna farms!

http://dodgeblog.s3.amazonaws.com/docs/SWM-GoogleEarth.kml

It’s also available directly from www.myke.me/shortwavemusic/ along with the normal maps version and the comprehensive spreadsheet.”

This is fascinating–thanks, Myke!

I’ve already checked out the Google Maps version online but will certainly download the KML file and import it into Google Earth as well. It’s fun zooming around the globe and finding all of these transmitter sites; this took serious dedication to plot. (To have had tools like this when I was eight years old…)

Note that the next season of shortwavemusic starts on October 1st. Check out Myke’s website for more details!

Alex updates his shortwave frequency charts

AlexChartsSWLing Post reader, Alex, has just informed me that he’s updated his shortwave frequency charts once again. Alex said he has, “improved the layout of the charts so that they have a bigger, clearer type.” He continues:

“They should be more legible this time, even if you print off from a basic printer and carry the bits of paper around when travelling. They also now divide the day into Early and Late, rather than Dark and Daylight, which seems to work better.”

Note that Alex creates his charts based on actually listening to broadcasters, rather than importing schedules from other sources.

You can download the free charts on his website:
Shortwavetimes.com

Here are the direct links to download the charts:

Thanks, Alex, for the time and dedication you put into these fine charts!

Voice of Greece update

GreeceFlagGood news from our reader and regular Greek correspondent, Christos:

I listen to the programmes of ERT, almost everyday.
They continue transmitting as usual, with full programming, even these days around 15th of August (Virgin Mary Day) which is the peak of the Greek holidays. Other years we had a 2-3 minutes news bulletin and a lot of uninterrupted music.

I have written some comments about it in my blog but only in Greek.

I also have another post with photos of the radio programming producers. I am sure you have listened to some of them from the VoG.

Christos then sent this listening report:

I have checked the frequencies of VoG at my summer house in Marathon. I found out that VoG is on air on 7450kHz and 9420kHz. I couldn’t hear anything on 15630kHz, the one that was active yesterday.

Be sure to check out Christos’ blog for more details (in Greek).

Additionally, Moshe commented on my last post with this logging:

VOG Was heard last night at the 19 Meter band (I was monitoring it with my tube radio, later on confirmed it on 15650KHz).

As for now, VOG is on the air on 19 Meter Band.

Thank you, Christos and Moshe–you’ve set my mind at ease for the moment. In my current travels I can’t easily receive VoG with my portable, so I’m grateful for these reports.

Jeff designs an SDR “Go Kit” around the Softrock Ensemble

SoftrockGoKit1Jeffrey Fritz (WB1AAL) contacted me with details about his SDR (Software Defined Radio) “Go Kit” and has kindly allowed me to post it.

Jeff writes:

As a reader of the SWLing blog, I know that you are very interested in SDR. And you probably know that a “Go Kit” is a portable ham radio system in a case that can be moved at a moment’s notice and set up at another moment’s notice virtually anywhere.

I have a VHF Go Kit made up for emergency events. It is complete with waterproof carrying case, Aden PCS-7000H two-meter transceiver, a Kenwood VHF tuner, a Kenwood SW-100 VHF SWR bridge and two antennas (a 2-meter J-pole made out of twin lead and a two meter mag mount.) But what if there is a need to monitor the HF bands during the same event?

Now that I own a Flex-1500 SDR transceiver, the Softrock Ensemble SDR receiver that I bought a while ago has become somewhat redundant. It is still a serviceable radio and works fine, but it can’t hold a candle to the amazing Flex-1500. While I could turn it into a panadapter or sell it on eBay, eHam, etc., I had a better idea.

To monitor the HF ham bands, I could use something like my Grundig G3 shortwave radio in my Go Kit. While it is portable, battery operated and will tune LSB and USB, listening to SSB or even CW in an emergency situation with the G3 can be a bit of a chore. (Think of the old boat anchors with their main tuning and fine tuning band spread dials, but now make both dials tiny and you’ll get the idea.) Instead, why not build a 12-volt battery supply with common, easy to obtain batteries? I could connect it to the Softrock Ensemble and then via a USB audio interface to a battery powered laptop. Add a pair of headphones and we are in business.

That is just what I’ve done.

I’ve attached some photos of my most recent project–done this past weekend actually. [Check out photos above and below] It’s an SDR Go Kit. One of the attached photos shows the laptop and the Softrock Ensemble SDR receiving 40-meter band SSB while entirely being operated on battery power. There is no power switch. You simply pull the DC jack out of the Softrock Ensemble SDR radio when it isn’t in use. Simple as it gets! The other photo shows the battery pack built into a (ahem!) Preparation H Pad holder pack. (Now, I am not saying who used this!)

Ah but what will battery life be like with 8 C cells in series driving the receiver? It’s too soon to say because I just put it together an hour ago. But here’s a guess:

SoftrockGoKit2The Softrock Ensemble draws 18 mA at 12.6 volts (my measurement.) An Alkaline ‘C’ battery can supply up to 8,000 mAh, so doing some math and assuming fresh batteries, the battery pack should run the radio for roughly 400 hours. (Hopefully my math is correct!) If so, then I think that the laptop batteries will give out long before the life span of the C Cell is reached!

73,

Jeff, WB1AAL

Jeff, this is an excellent use for the Softrock Ensemble. I imagine it will run for a very long time drawing only 18 mA. I have a “Go Kit” for QRP ham radio purposes and one for SWLing during travels. You’ve inspired me to piece together a proper receiver “Go Kit” to be used in case of emergencies.

Readers: If you have a project, like Jeff, that you’d like to share on the SWLing Post, feel free to contact me with details!

All Night Flight: Weiskopf takes us on an audio journey

ANF_WebI’m a big fan of practically anything that Myke Dodge Weiskopf produces.

We’ve mentioned Myke numerous times on the SWLing Post; based in Los Angeles, California, he’s a radio producer, historian, broadcast artist, multi-instrumentalist, sound recordist, and composer.

Recently, I noticed that one of Myke’s audio mixes, ALL NIGHT FLIGHT, was featured on the über-cool experimental radio broadcast platform, Radius.

In Myke’s artist statement on Radius, he describes this mix simply:

This edition, produced exclusively for Radius, is a 73-minute distillation of the inaugural «ALL NIGHT FLIGHT» performed, created, and mixed live by Myke Dodge Weiskopf in the desert of Joshua Tree, California, on 20 July 2013, 10 PM – 5 AM PST.

I have embedded this mix below, but encourage you to check out Radius for his detailed mix description and Myke’s homepage for details on ALL NIGHT FLIGHT and his other interesting projects.

So, go ahead: put on your headphones, relax in your listening chair, and let Myke take you on an audio journey…
