ERR TXG No Power Output

Jim McCook W6YA
I have a spontaneous K3 failure after making no changes. This morning my
K3 has only 1 or 2w power output when set to 100w or around 32w when the
KPA1500 is turned on and set to OPER.  It's the same on all bands and
with a dummy load.  It worked fine last night for several QSOs.  I tried
a 5w TX GAIN calibration but it failed with erratic, varying low power
readings.  I loaded a previous Configuration file but that didn't help. 
Whenever I press TUNE I get the ERR TXG message after shutting it off. 
Power in TUNE is set to 50w, but when I hold TUNE the display flickers
between 2 and 8w.  Any ideas?  Jim W6YA

Hi Jim, are you seeing these issues with the control cable between the
K3 and the KPA-1500 connected?  Are you reading these output numbers on
the K3, the KPA-1500 or an independent power meter?
