[Elecraft] K Line: Signal loss in a QSO

[Dave]

Hi,

If it were me, I would bypass everything and feed the antenna directly 
to the K3.  If things work after that step, it is not the K3.

Again, if it were me, I would begin adding things back, one at a time, 
until the failure returns.  At that point, I would conclude that the 
last device added was failed, and look there.

If it is the K3, I would then come back from my last backup of the 
settings and see if that fixes things...

If that fails to bring the K3 back, I would re-post my question, with 
all the test info I have gathered above.

I would call support, but the last time I called, I got a message, not a 
person.

73, and thanks,
Dave (NK7Z)
