17670 kHz: Music 4 Joy has started @ 1300z, bringing Sunday airings of this strange, single-track-in-a-loop broadcast to a revival indeed, as announced to happen in July :) weak on Twente #WebSDR, perhaps even weaker here in NE Poland. Should be better @ 1800z on 11800 kHz or 1830z on 9755 kHz.

And if/when you have a good signal, watch out for howling sound in audio mid-range, perhaps around 500 Hz, in a sort of notch of the music - suspected mystery data in there 👀 #shortwave #UNID #mystery
