[Elecraft] QSK and Monitor on the K3

[Ed Muns]

I ran QSK all weekend in the CQP with the K3 driving an Alpha 87A and a Pro3
driving another 87A.  I like to reduce the monitor level as low as possible
and on the K3/87A combo, it was extremely quiet and smooth.  But the Pro3
could not subdued by comparison.  First of all, even with the sidetone
reduced to zero, there was still leakage that was much louder than what the
K3 could be adjusted to.  In addition, the Pro3 had popping and "slapping"
on the TX/RX transitions between code elements that was very tiring.  The
Pro3 in one ear made it impossible to copy weak signals on the K3 in the
other ear.  I was constantly having to manually switch the headphones to the
K3 only when working a station on that radio.  The other way was fine ... K3
transmitting in one ear while copying a weak signal on the Pro3 in the other
ear.

At least six K3's were on in the CQP: AB7R, N0SS, W6GV (K2VCO), N6XI, K7RAT
(N6TR) and K6YT (W0YK).
