Many thanks to SRAA contributor, Scott Nelson, who notes:
Voice of America recorded off shortwave (15.410 MHz) on December 24, 1986 [starting around 1959 UTC]. The receiver was a Sony ICF-6500W with a random wire antenna. Recorded to cassette tape and later transferred to an mp3 computer file. The broadcast features Christmas music, IDs, News, and the Nightline Africa program.
