A bunch of them here.

My favorites were Radio Nederland and Radio RSA (South Africa)
I always enjoyed also the swinging version of “Moscow Nights” they played on Radio Moscow.
Radio Moscow sometimes broadcast music of a Russian band that played New Orleans-style jazz. Not everything was grim propaganda. Sometimes there was something fun. Back in the 60s, 70s, and 80s, you didn’t have streaming technology with hundreds of channels.
