"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."
