[Elecraft] K3 RX in real world

One thing I notice with better and better RX with less and much less RX
generated cr*p, is that TX/amp generated cr*p is presented quite a bit
clearer with much less disguise. Once upon a time that was all "band noise"
to us. Ain't clarity interesting?

What is really cool is to listen to an SSB pileup in correctly done K3
diversity and hear cr*p coming from the same point on the sound stage as
just one of the voices, not at all spread around like the true "band
noise".
