Dan Shares Recordings of the Golden Days of European Shortwave Listening

Many thanks to SWLing Post contributor Dan Greenall, who shares the following guest post:


Europe on shortwave in the 1970’s

by Dan Greenall

During the golden years of shortwave listening, many European countries had an international shortwave service and broadcast programs to North America (where I live) in English. As a result, these stations were usually among the first that a newcomer to the hobby would find.  However, since there was no internet or e-mail, schedules often had to be found in the various club bulletins and hobby magazines.  QSLs arrived through the postal system and could often take months to arrive.

I soon developed the habit of making a brief recording of each station as additional “proof of reception,” and many of these have survived to this day.  These were typically made by placing the microphone directly in front of the speaker of my receiver.  In recent years, they have been uploaded to the Internet Archive, and links to some of them from the early 1970s can be found here.

100 Years Ago: A Teenager in Iowa Reaches Greenland by Radio

Arthur A. Collins Legacy Association celebrates 100th anniversary of major radio breakthrough in Cedar Rapids

CEDAR RAPIDS — Years before the first trans-Atlantic phone call, and decades before international direct dialing would become available, a Cedar Rapids teenager had a direct line to one of the most remote places on earth.

And decades before companies like Collins Radio and Rockwell Collins became multibillion dollar enterprises, a 15-year-old’s ham radio was connecting Arctic explorers with the world from an attic on Fairview Drive.

On Aug. 3, 1925, Arthur A. Collins made headlines as the first person to communicate with MacMillan scientific explorers in Etah, Greenland on short-length radio waves — what The Evening Gazette in Cedar Rapids hailed as “a new chapter into the history of radio.”[…]

HCJB Quito, Ecuador – Then and Now

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

In the 1970s, the powerful signal from radio station HCJB, the Voice of the Andes, in Quito, Ecuador, could be heard with station identifications (similar to this one circa 1971) being given between programs.

I am led to believe that they were made by the late Bob Beukema (1928-2001), since his resonant radio voice was often referred to as the “Voice of the Andes”. My listening post at the time was Ancaster, Ontario, Canada.

Today, the station can still be heard broadcasting from Ecuador, albeit with much lower power, perhaps 10 kW at the most, and a much simpler antenna arrangement.

The accompanying recording was made July 30, 2025 on 6050 kHz around 0200 hours UTC using a Kiwi SDR located in Lima, Peru. Even though programming is only in Spanish and indigenous languages, some of that wonderful Andean music can still be found here.

Dan Unearths Radio Memories: A 1990s Treasure Trove of Broadcast Ephemera

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

Hi Thomas

Before the days of the internet and e-mail, handwritten or typed reception reports mailed out to broadcast stations would often net the lucky DXer other goodies, including station brochures, program schedules, frequency guides, station stickers, blank reception report forms, pennants, booklets, and other items in addition to that coveted QSL verification.

The QSLs were stored carefully away in albums or shoe boxes, while much of the other paper ephemera eventually (over the years) made its way into a recycle bin. Recently, while cleaning out some storage boxes in the basement, I came across a number of envelopes containing some of the aforementioned items from the early to mid-1990s. To preserve these newly discovered pieces of radio history, I have scanned much of the material and included it here.

Here’s a sampling:

History of the Radio Intelligence Division Before and During World War II

Many thanks to SWLing Post contributor Mike, who writes:

Good afternoon, Thomas. Recalling that there have been a few postings on the SWLing Post over time on the FCC’s Radio Intelligence Division, I thought this might interest you and some readers. I just came across this (I don’t even remember what linked me to it) and have only briefly looked reviewed it, but the manuscript appears to be pretty interesting. https://www.qsl.net/w3df/sterling/ridhist.pdf 

Additional history can be found here: https://www.qsl.net/w3df/sterling/dfh1.html.

An interesting local (to me) tidbit on page 19: “It [RID] patrolled the outside of the Oak Ridge, Tennessee installation, the scene of the Manhattan Project but without the personnel knowing what atomic developments were being made inside.

Fascinating! Thank you for sharing this, Mike.

Podcast Explores History of Parque do Rodeador

Many thanks to SWLing Post contributor Rich Cuff for this tip: EBC has released Parque do Rodeador: Half a Century of Transmissions, a five-part radio documentary (in English) exploring the history of Brazil’s Rodeador Transmission Park—one of Latin America’s most powerful broadcast centers. Launched in 1974 during the Cold War, it enabled Rádio Nacional’s shortwave and medium wave signals to reach across continents. The series covers its political and technical legacy, including Brazil’s international broadcasting efforts, the challenges of aging infrastructure, and the future of digital shortwave. Listen here.
