Old Codger - I was a teenage listener to the offshore stations and it was amazing how their signals travelled. Even in the middle of a Summer's day, Radio City was listenable on my valve radio. Radio London was about the same, but Caroline South was hardly there at all. Caroline North was OK but not strong here in East Manchester, although it quickly improved if we went West of the city in the car.
I think the prevailing noise level was much lower back then. Nowadays there's a 'fug' of hash & buzz across most of MF.
It'll be a challenge to receive Caroline on it's new legal frequency at the low power, but I'll certainly give it a go. Early evening is often a good time for this kind of reception.
