HPR4685: Listening to SSB stations in the early 1980s

Lennart tells about the shortwave radio he had in the early 1980s and what he could hear on it, for example he marine band, amateur radio, CB and of course broadcast stations. The radio did not have a BFO to demodulate SSB stations, but using a second radio close by and using its local oscillator he could still make those signals intelligible.
