K3 Power Out

[ghaffly]

I have K3 serial number 2802 with the 100 watt option. All was well until
today.
Currently there is zero to minimal output.
Rotating the power knob to 12 watts you hear the relay. Regardless of power
setting
only 1 bar on the RF is lit.The fans are workings.
Rechecking the TX calibration it failed at 5 watts with the ERR TXG message
on the display.

Where do I start?

Glenn,

This happened to me recently, and in my case it was a TMP cable between
the KREF3 board and the RF board that had become dislodged. No doubt
there are other possible causes, but that's a relatively easy one to check.

Glenn,

Can you do the Transmit Gain Calibration manually (from the menu - see
the K3 manual)?  Try it - it must be done on each band, and should be
done forst at the 5 watt level and then the 50 watt level.  Which bands
succeed and which bands fail?
