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?

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? 73, Pete N4ZR Check out the Reverse Beacon Network at <http://reversebeacon.net>, now spotting RTTY activity worldwide.
