In Europe, there are several high power broadcasters starting at 7100
kHz, which would easily overload the 40 m receiver. Assuming loaded Q


OH2BT's comments about how much better things have gotten in Europe really
made me say hmmmm.... I only recently heard actual measurements, rather
than whining, and things are pretty horrible today - they must have been
intolerable decades ago.


We had problems keeping Radio Moscow out of _audio_ equipment :-).

Guitar amplifiers were quite problematic with long cables and a top
capacitance (the guitar and the player) at the end, bringing quite
large RF voltages into the audio stages, causing rectification in
unfiltered input stages.
