Audio files from solar cycle 22

[kkn50]

I recently found a couple of old cassette tapes with VHF low band comms from solar cycle 22 (September 1986 - May 1996 with maximum monthly Smoothed Sunspot Number of 158.5 in July 1989) and am in the process of converting them to digital format. Some audio I recorded, some was sent to me by fellow low banders in the 80s.

I will upload a few of the better intercepts for the benefit of those who missed the great propagation of the late 80s.

Audio files will be here: http://sites.google.com/site/okiesam/solar-cycle-22

Let me know if you find interesting.

Crazy, sounds like Transcrypt 430 or 460 scrambling. It's definitely their flashcall signalling. RayAir could probably pull some audio from it. He's good with that stuff.

He did and corrected my description: "That's Selectone ST-25 rolling code frequency inversion."
