Radio 390 had some announcements where it claimed to be "Britain's most powerful commercial radio station". Its chosen frequency and efficient aerial no doubt helped. I read somewhere that the BBC reckoned 390 was using 60kW but the only references I have ever found are to an RCA 10kW transmitter installed when new finance came in and 390 replaced the ailing KING Radio.

773 was a very good frequency. Caroline used it in 1973 when off the Dutch coast for their all-day English service (before the short-lived first lattice mast on the Mi Amigo collapsed) and it was a good signal into the midlands. I remember listening during school lunch breaks. There were a few technical issues getting 773 and 1187 running simultaneously and apparently no more than 8kW was used on 773.
