During the spell of very high pressure (that sent my barometer off the scale) a few weeks back I noticed that Caroline was unusually strong on 648kHz in the daytime.

I normally associate high pressure with VHF 'lift' conditions - this is the first time I've noticed a potentially associated effect on AM but then I'm not a DXer and all the BBC national stations are only a few miles away at Droitwich so always solid.

Having said that I was listening to Manx one night on my little Grundig - it had remained tuned to 1368 since a Caroline North broadcast - and when Manx went into a long deep fade I could hear another very weak station slightly off frequency. I tuned it (not enough to be 9kHz away) and could discern the music but not the speech. As 1368 is a clear frequency now I suspect I might have been hearing something from across the pond.
