WWV changes announcement format: July 1, 1971

Shortwave Radio Audio Archive contributor, Brian D. Smith, recently contacted me; I was enthused when he described the recording he was sharing:

"This recording captures the last 5 minutes of WWV’s old format (giving the time every 5 minutes) and the first 5 minutes of the new format (giving the time every 1 minute), which took place on July 1, 1971 UTC.

Apologies for the less-than-stellar audio quality, but I recorded this as a 15-year-old fledgling SWL with limited knowledge of audio recording techniques. So I simply placed the microphone from my cassette tape recorder next to the speaker on the receiver and hit the record button. The signal quality wasn’t the greatest, either — lots of QSB and QRM — but I still managed to get what I was going for.

The resulting recording has accompanied me everywhere since then, preserved only on its original cassette, until 2008, when I finally decided it was time to learn how to transfer it onto my hard drive, burn it onto a CD and stop having to rely on the integrity of 37-year-old audio tape.

Even as a teenager, I regarded the WWV changeover as historic, and felt I should attempt to record it for posterity. Consider yourself posterity!"

Brian received this broadcast on 10 MHz care of a Hallicrafters S-108, with random length of wire attached to the back of the receiver serving as an antenna. Location was Franklin, Indiana.

As Brian mentions, the audio quality is a little rough, but this is still quite a treasure of a recording!
