Radio Time Travel: Brian’s 1974 shortwave radio recording

Many thanks to SWLing Post and SRAA contributor, Brian D. Smith (W9IND), for the following guest post and recording.

Shortwave Radio 1974: Canada, Argentina, Spain, West Germany, Albania, utility stations

Want to know what shortwave radio sounded like in 1974?

This 55-minute recording, recovered from a cassette, was never intended to be anything but “audio notes”: I was an 18-year-old shortwave listener who collected QSL cards from international stations, and I was tired of using a pen and a notepad to copy down details of the broadcasts. I wanted an easier way to record what I heard, and my cassette tape recorder seemed like the perfect means to accomplish that goal.

But it wasn’t. I soon discovered that it was simpler to just edit my notes as I was jotting them down — not spend time on endless searches for specific information located all over the tape. To make a long story shorter, I abandoned my “audio notes” plan after a single shortwave recording: This one.

Still, for those who want to experience the feel of sitting at a shortwave radio in the mid-1970s and slowly spinning the dial, this tape delivers. Nothing great in terms of sound quality; I was using a Hallicrafters S-108 that was outdated even at the time. And my recording “technique” involved placing the cassette microphone next to the radio speaker.
Thus, what you’ll hear is a grab bag of randomness: Major shortwave broadcasting stations from Canada, Argentina, Spain, Germany and Albania; maritime CW and other utility stations; and even a one-sided conversation involving a mobile phone, apparently located at sea. There are lengthy (even boring) programs, theme songs and interval signals, and brief IDs, one in Morse code from an Italian Navy station and another from a Department of Energy station used to track shipments of nuclear materials. And I can’t even identify the station behind every recording, including several Spanish broadcasts (I don’t speak the language) and an interview in English with a UFO book author.

The following is a guide, with approximate Windows Media Player starting times, of the signals on this recording. (Incidentally, the CBC recording was from July 11, 1974 — a date I deduced by researching the Major League Baseball scores of the previous day.)

Guide to the Recording

0:00 — CBC (Radio Canada) Northern and Armed Forces Service: News and sports.
7:51 — RAE (Radio Argentina): Sign-off with closing theme

17:00 — Deutsche Welle (The Voice of West Germany): Announcement of frequencies, theme song.
17:39 — Unidentified station (English): Interview with the Rev. Barry Downing, author of “The Bible and Flying Saucers.”

Shortwave Radio Recordings: EAM messages

StrategicAirCommand

Inspired by SWLing Post reader @K7al_L3afta, a few weeks ago, I monitored 15,016 kHz for US Air Force EAM (Emergency Action Messages).

I’m no expert on military communications, but I did manage to catch a few messages–that I assume are EAM(?)–on the same frequency.

All of these recordings were made on the afternoon of February 15, 2015 on 15,160 kHz in the upper sideband:

Catching a USAF HF-GCS transmission in Morocco

My buddy, @K7al_L3afta (on Twitter), posted this interesting recording of the US Air Force High Frequency Global Communications System on 15,016 kHz USB at 18:01 UTC yesterday:

HF-GCS-logoI don’t believe I’ve ever heard or noticed this type of USAF HF-GCS transmission before.  Sounds almost like a numbers station.

Update: SWLing Post reader, Daniele, comments:

It’s an EAM, “Emergency Action Message”:

Thanks, Daniele!

As I’ve mentioned before, @K7al_L3afta lives in an urban area of Morocco and his shortwave radio listening is plagued with radio interference (RFI). Still, he seems to snag some interesting catches on the shortwaves just like this one which he said he caught by “turning the tuning knob randomly.”

Serendipity is, indeed, the best type of SWLing!
