Frans checks out the MRA-QRP 20W QRP Passive Loop Antenna

Many thanks to SWLing Post contributor, Frans Goddijn, who writes:

Dear Thomas,

In the following video, I show a little loop antenna that I bought online from AliExpress:

On arrival one of the parts, the semi-transparant box with variable capacitor for antenna tuning turned out to be broken due to the bigger box having been thrown around in transit.

The seller promptly provided me with the necessary part (plus extra) for repairs.

Yesterday I repaired it and today I assembled the antenna and tested it a bit in the afternoon and early evening as soon as reception started to get well enough.

It’s a fun antenna, affordable too.

The video shows how effective the variable capacitor is.

Best regards,

Frans

Thank you, Frans. That is certainly a very affordable passive loop option. If you’re an urban QRPer, all the better. I should also mention, you have one of the nicest radio operating positions out there!

Sri Lankan Broadcaster Goes DRM Following Listeners’ Request (DRM Consortium)

The international service of the Sri Lankan Sri Lanka Broadcasting Corporation (SLBC) recently doubled its Tamil Service airtime to two hours, on 873 kHz AM (medium wave) from Puttalam transmitter. The new schedule is 0130-0330 UTC (7.00 am to 9.00 am IST). This is partly in response to individual efforts of listeners, many in the southern part of India, in Bengaluru. Introducing this change, Colombo International Radio also announced that shortly they are going to use DRM on 1548 kHz! This will be done by is using the old transmitter of Deutsche Welle located in the north of Sri Lanka at Trincomalee. The Sri Lankan public broadcaster has started airing the DRM announcement:

The publicity for the new DRM service is in full swing. See video:

Czech Radio centenary: Listeners send congratulations (Czech Radio)

On the occasion of Czech Radio’s centenary, we asked our listeners to let us know where they heard our special programme on that day in order to map Radio Prague International’s broadcast reach today. Here are at least some of the many letters and photos which you have sent us. Thank you to all our loyal fans.

George Jolly, who was listening to our special programme over the internet, wrote from Houston, Texas:

“Thank you so much for the special program today celebrating your 100 years of radio. If I were not so far away, I would surely visit you on Saturday. It means a lot to me that you continue the tradition of the ‘radio magazine’. Hearing the opera excerpt and other recordings from the past was wonderful!

“I love old music and old technology like radio, and I love that you are keeping their spirit alive and new again for today’s world. I am so grateful to celebrate your centenary with you from afar.”

Another listener from the United States is Timothy Marecki, who wrote us from New Port Richey in Florida: Continue reading

Don Moore’s Photo Album: Western Venezuela

Many thanks to SWLing Post contributor, Don Moore–noted author, traveler, and DXer–for the latest installment of his Photo Album guest post series:


Don Moore’s Photo Album: Western Venezuela

by Don Moore

I started this series several months ago with pictures of Ecos del Torbes and other stations in San Cristóbal, Venezuela. This time I want to take you to the other places I visited on that trip to Andean Venezuela in January 1995.

When I started DXing in the early 1970s, Venezuelans were the most commonly heard Latin American shortwave stations. The 90- and 60-meter bands were full of them and there were more than a few to be heard in the 49- and even 31-meter bands. But the Venezuelans began abandoning shortwave before other countries in the region and by the late 1970s their numbers had been considerably thinned. Only a handful remained in the early 1990s.

This radio dial [click to enlarge] goes back to a time when Latin American stations were found all over the radio bands.

One of the last Venezuelan stations to leave shortwave in the 1990s was Radio Valera in the busy commercial city of Valera.

For decades, Radio Valera was one of the best heard and most consistent Venezuelan stations on 60 meters. Roque Torres Aguilar, waving on the left side, was station manager at the time of my visit.

I’ve found listings in DX publications for their 4840 kHz frequency as far back as 1946.

I was given this 59th anniversary key chain when I visited Radio Valera in January 1995. So the station must have begun around 1935.

Station studio in 1995.

A second shortwave station in the state of Trujillo was Radio Trujillo in the nearby town of the same name. Broadcasting on 3295 kHz, they were one of the easier catches in the 90-meter band in the early 1970s but were gone by the late 1970s. Continue reading
