Hi Scot
my x6100 had the problem of alc 100 and no power output while plugged in CAT control and in FT8 mode, I believe the cat control crashed my radio,
I took the measurement of the AFT5M31N with my multimeter, it seems to me to be good, I replaced the AFT5M31N and my tests were always negative (alc100 no power). I said to myself I will wait for a new version of the firmware.
I must have been lucky with firmware 1.1.7 now the radio transmits very well, I'm afraid to use the CAT to crash my radio again!
I did nothing special
I flashed several firmware version
I replaced the AFT5M31N
and I flashed version 1.1.7 which luckily solved the problem.
Thank
Real
