[Elecraft] KX3 BC Breakthrough

[Ron D'Eau Claire]

If turning the Preamp off fixes the problem, that would be my first choice
as long as I can hear the noise level drop when I disconnect the antenna. 

If removing the antenna doesn't cause the noise level to drop, then the
preamp is likely useful for hearing weaker signals. In a QSO I'd still turn
the preamp off to see if it affects my ability to hear the other station. 

Putting too much gain at the antenna input compromises the performance of
any receiver

Paul,
I have this direct AM detection on my KX3 every day mainly on 20-15-10 m
bands/ I would not call it a problem because shifting IF 8 kHz solves it
100%. Although this disables dual RX but one seldom (if ever) needs it on
this portable  QRP transceiver.
Yet the radio is the best available choice for traveling and it has got very
good receiver.
