This morning I listened to Radio City via Channel 292 on 9670 and 6070 kHz. A nice mix of lesser known oldies, including some French songs that always give you that “summer feeling”. Within an hour I received the above QSL which gives some information about the format. The 2nd page of the QSL (not shown here) gave information about the music that was played.
The “Tower of Power!” logo on the QSL confirmed what I already suspected. The station is named after the offshore radio station. The original Radio City was active between 1964 and 1967 from the Shivering Sands Army fort in the Thames Estuary. These were the wild days of offshore radio in the UK, culminating in Radio City’s manager Reginald Calvert being killed by Oliver Smedley, former manager of offshore Radio Atlanta, in a violent row about a transmitter sale.
