[Elecraft] Need for advice was; noise reduction

[Don Wilhelm]

  Tom,

I believe that is time to put the K3 into diversity receive which should 
stop the "whooshing" if it is related to frequency/phase differences 
within the receiver.  Without the phase locking that is inherent in 
diversity mode, that "whooshing" is a natural consequence of slight 
phase and frequency differences.

OTOH, if it is related to phase differences coming from the antennas, 
there is no cure without work at the antennas - the receivers are doing 
their proper job of translating their independent RF inputs to baseband 
audio.  In diversity mode, the audio will be heard from both channels 
and it is up to the human brain to figure out which one is the best to 
listen to
