[Elecraft] Second Receiver Discussion

[Lyle Johnson]

> Would someone like to expound the virtues and advantages of adding the second receiver to the K3?  I want to know what I could gain from have a second receiver in the K3.

One reason I really wanted the second Rx in the K3 is from experience 
long ago in a town far, far away.

QRM WARS

I used to have a regular sked on 20 meter SSB with a friend in New 
Zealand.  He was running low power to a simple dipole and his signal was 
often as weak as mine.

Once we had our QSO going, someone would invariably stomp on his signal, 
tuning up and calling CQ, and then getting abusive if told that there 
was QSO in progress.

(I know this never happens in the polite society of the 21st century, 
but it did in the early 1980s.)

I then acquired a used Signal/One CX-7A.  It had dual receive.

After that, once our QSO started, I'd tune around with the second 
receiver to locate a clear spot.  When we got QRM'ed, I'd tell him the 
new frequency, and instantly QSY to it and call him.  Once we were 
chatting on that frequency, I'd tune around with the second receiver 
looking for a clear spot...
