During the peak of Solar cycle 22 in 1989-1991, amateur radio operators (including me) on the US west coast used to listen for New Zealand channel 0 audio on 50.75 MHz (also 50.74 and 50.76 MHz). If you could hear the wideband FM audio, it was almost guaranteed you could make SSB or CW contacts with New Zealand hams around 50.11 MHz.
