[Elecraft] K3 Diversity and filter selection

[Steve Ellington]

So it could sound like being in a jet airliner with engines out of sync? 
That happened to me once. I was in the back of a plane which had 2 rear 
engines. It felt like my head was about to explode! Anyway....It would be 
nice if DSP could compensate for that instead of buying expensive filters.
