K3: High-Power TX Gain Calibration - No Output

I am having problems with the 50 watt TX Gain Calibration, it shows 0
watts and gives the error "ERR TXG". The Low-Power 5 watt test
worked fine and have low power output.

Anyone had and resolved this problem?

Running FW 1.88

Thanks,

Have you initialized the PA in the menu and turned the rig off and on
a couple of times?

Dave, PA is set to nor and have turned off/on multiple times.
Just checked the Circuit Breaker, it's making contact.

Re: Fwd: K3: High-Power TX Gain Calibration - No Output

I would next open up the K3 update tool, and under the Configuration
tab, select the click on the Edit Crystal Filters... button. In what
ever mode you were getting the TX error on, ensure that one of buttons
on the bottom 4 (including FM if applicable) lines is selected for
that mode. As an example, in my case, the 2.70 filter is selected for
Tx CW, Tx SSB, and Tx AM.

I fixed the problem. Removed KPA3 and found a gray wire out of T1, at
the C1 end, was under the mounting bracket (KPA3 to RF Shield). The
K3 now puts out full power and the High Power Gain Calibration is
complete for all bands.

Thanks Gary at Elecraft for the excellent help.

And thanks to all of you for your comments and suggestions.

What a nice receiver!!!
