[Elecraft] Digital Modes (PSK31 and JT-65) not working on 40 meters

2016-01-30 Thread Larry Snyder 
PSK31 and JT-65 stopped working on 40 meters. . Initially I see the PO at 45
watts but then it immediately backs off to a fraction of a watt with no or
very little modulation on the P3 with the transmit monitor.

 

I change to 20 meters and everything works just fine.  Same computer, same
everything - only thing changing it the band switch on the K3??

Larry,

Try doing the TX Gain Calibration.  It is quite easy to do from K3 
Utility.  If it fails in K3 Utility, then try doing it on a band by band 
basis as indicated in the Calibration section of the manual.
