I have used twin K3's for over a year with good results.
FW 3.27 using K1EL winkey and all rig control via usb.
-----
Whilst running a contest this weekend recvd a report of bad keying. Sounded
fine to me (sidetone).
But I put the other rig on the second harmonic and was shocked to hear
REALLY chopped CW. My first thought was a high resistance connection between
winkey and the CW jack on the K3.

A half hour later it was isolated to my having set the TX DLY to 15 (or
higher). Returning it to NOR/8 resolved the problem.

Keying via paddle in the K3 worked ok. It only happened using keying from my
logging program (n1mm)- twiddling the winkey parms in N1MM was a waste of
time.

Might be worth a heads up as you -will not- hear the chopped CW in sidetone
or sending with a paddle.
Bottom line is keep the TX DLY at Normal 008 unless you have a real need.

73, Howie N4AF
