Re: Radio 4 heard on 396kHz
Strong clear 396kHz signal here in SW edge of London (Eddystone 670A, short vertical wire). I first noticed this signal a few days back at the extreme HF end of the LW band of this set and assumed it was a sprog of some sort but hadn't got round to doing the possible maths permutations. Yes, second harmonic of the transmitter sounds plausible, it's like having the pre-war "MLW" band back!
