Definitely still two transmitters on 1548 kHz.
1548 appears to be dead this evening so Sheffield must have been switched off already. Somebody further north could confirm if Colinswell in Scotland has been switched off. I can still hear very weak het on the channel so could be something on or close to 1550 from very far away (East, most likely? beating with a low power somewhere in Europe. The channel appears to be a clear channel by night and day at my location in Essex now.
