Shortwave Radio Recordings: Alcaravan Radio

casa trans. antena AM

Alcaravan Radio’s antenna site and transmitter house.

Yesterday, August 8, I was able to record Alcaravan Radio out of Puerto Lleras, Columbia. Alcaravan Radio broadcasts domestically on medium wave and also on 5.91 MHZ shortwave, from 23:30-12:00 UTC.

Though typical summer conditions meant for a higher noise levels, Alcaravan’s 1 kW signal still punched through the static and made for pleasant listening. In this recording, I was using the WinRadio Excalibur, but I listened for a couple of hours on the Elad FDM-S2 as well–both did an equally good job while connected to my large sky loop antenna.

To be clear, 1 kW is low output power by international broadcasting standards. Alcaravan Radio was not audible on the Tecsun PL-660 nor the Sony ICF-SW7600GR, though I have heard them on portables in the past during the late fall and winter months. Still, you might be able to snag them on a portable when summer conditions are favorable!

goTenna: Turn your smartphone into a text transceiver

goTenna

Many thanks to SWLing Post reader, Richard Cuff who has apprised me of the goTenna: a small device that allows you to use your smartphone to send and receive messages and share your GPS location with others without the need of mobile phone service.

goTenna describes their device:

“goTenna is a small, rugged device designed to make “No Service” no problem. Just pair your smartphone with a goTenna and communicate off-grid with those near you who also have goTenna, anywhere on the planet, regardless of access to cell reception or wi-fi. goTenna allows you to send and receive texts and share GPS locations on beautiful offline maps, without ever relying on central connectivity. Depend on it in all kinds of situations: when hiking in remote areas, traveling, attending music or sporting events or during an emergency. Plus, because goTenna is end-to-end encrypted, it’s not just for when you’re off-grid, but when you want to be.”

Some sources claim the goTenna is based on “short-wave” radio frequencies;  I discovered that it operates between 150-154 MHz, so this is not the case.  Still, it would be fascinating the see the potential in a device that could use the HF spectrum to create a smart phone mesh network. Though the antenna would need to be longer, communication distances in rural areas could surpass that of VHF frequencies. In the end, text messages would be an ideal format for such a system.

VOA Greek language service to end Tuesday, August 12

voa-greek-serviceMany thanks to TheGreekRadio.com for commenting with details about the August 12 closure of VOA’s Greek language service and allowing the following article to be republished on the SWLing Post:


End of an era: The Greek Service of the Voice of America ceases operations

The end of operation of the Greek Service of VOA (Voice of America) after 72 years was announced yesterday by the radio network. The decision was taken due to cuts in the budget allocated for the operation of the news organization, but also due to the effort to use the broadcaster for the diplomatic needs of the United States. The last show will be aired Tuesday morning via satellite and it will be relayed to Greece by Skai Radio and City 106,1 in Thessaloniki. The first broadcast of the Voice of America, the official foreign-language radio in the United States was the February 1, 1942 in German with the announcer WIlliam Harlan Hale. The Greek was one of the 25 languages of the first network and airs on November 1, 1942.

The history of the Greek service

The presence of the Voice of America was very evident in the Greek territory, as the giant of American propaganda during the Cold War had settled in Greece, two of the most powerful transmitters in order to broadcast to Eastern Europe.

The radio transmitters of the Voice of America settled in Greece after the civil war, as part of the implementation of the Truman Doctrine. Then, the American state sent to Greece a set of equipment, “to facilitate the Greek Institute of Radio”, but which was used extensively for broadcasts programs from Washington. The first equipment arrived in 1949, and included a medium wave transmitter WESTERN ELECTRIC 50 KW and four shortwave transmitters COLLINS 30 KW, placed by the Voice of America in Perea Thessaloniki, by providing facilities for radio broadcast abroad: ‘Voice of homeland “of E.I.R (later the 5th of ERA). Also, the Voice of America originally had a floating the radio station on the medium wave powered 150 KW, aboard a ship called Courier, which was anchored in Rhodes and had its antenna mounted on a balcony.

The almost arbitrary installations of radio transmitters legalized later by a series of agreements between the American and the Greek Government and the relocation of equipment in Rhodes (Koskinous, Sgouros, Afandou), Xanthi (Dasochori) and Kavala (Agiasma). The last two agreements in 1997 and 2002, under which the American service undertook the responsibility to provide technical assistance and equipment (transmitters medium and short) to the Greek Radio. The transmitters in the Greek area set off in 2006, as part of policy to reduce shortwave. Then it was considered that the Greek stops as well, but the reactions of Greek-American associations eventually blocked the decision and the Greek radio program continued to broadcast via satellite, internet and FM stations as relayed by the Sky and the City International.

In 2006, despite the fact that the Voice of America left behind two very powerful transmitters, which could be used by the Greek Radio, eventually due to high maintenance cost , the broadcasting sites remained inoperative. Indeed, a few months ago, the abandoned facilities of the Voice of America in Xanthi to contain dangerous materials for the environment.


Readers: please contact me if you are able to record this final broadcast as I would like to add it to the Shortwave Radio Audio Archive.

Again, our thanks to TheGreekRadio.com who publishes news about all aspects of Greek radio on their site. Please check it out!

Ken’s favorite QSL card

W7LR-KenCarrRegarding memorable QSL cards, SWLing Post reader, Ken Carr comments:

“I received my favorite QSL card many years ago as a result of a random contact. I was just starting out in ham radio when I logged a QSO [contact] with a ham from Montana. I was thrilled because I knew how sparsely populated the state was. I once lived there for 8 weeks while studying at the biological station on Flathead Lake.

The very friendly and helpful ham from Montana was Bob Leo, W7LR. I promptly sent him a card and soon thereafter received one from Bob. Years later I was reading an article in QST. It was about a massive Dxpedition of 1947 sponsored in part by Hallicrafters. Hams from all over the country competed for the two coveted positions on what was called the Gatti Expedition. One of the hams chosen was Bob Leo!”

A photo of the card superimposed on the QST article along with more details are found on my Flickr site: http://bit.ly/1sxnL06

Thanks so much for sharing this memory, Ken!

SWLing Post reader, Steve Yothment (WD0HGB), writes:

“I received an “audio QSL” card from STF Radio International a few days ago. Have you heard about it? [The QSL] actually has grooves on the card that you can play on a phonograph. I had a friend play the audio on his phonograph and he converted the audio to MP3 format. Then, I decoded the digital info in the file.”

Victor Goonetilleke: The joy of DXing

SX-99-DialVictor Goonetilleke has kindly shared a passage he recently posted to Facebook. Victor pretty much sums up why I still listen to the shortwaves:

“For almost four score and 5 I enjoyed shortwave radio. Yes I was a DXer, and a dedicated listener. The thousands of hours of broadcasts I listened from the BBC, VOA, RNW, DW, RFI, Swiss Radio, NHK and many more of the international broadcasters influenced me over the years. The knowledge I gathered was transferred to hundreds of homes as I taught my students in class rooms and as a lecturer too in higher Colleges, in many social gatherings, day to day conversations with important people and everyday folks, what I gathered from my radio made them realize that there was a story out there.

And as the years went by one by one those stations started to go away and I became more and more a DXer and finally I have only those signals to bring me joy.

Tonight would you blame me for being a DXer, abandoned by the international broadcasters, if I sit back and enjoy this music through the crackle of shortwave and happy that I have a radio which few seems to understand these days.”

I would also encourage you to read Victor’s guest commentary on BBG Watch which was prompted by the BBG pulling the (shortwave) plug on much of Asia.
