Flex3000 power output oscillating intermittently.

Rolf Rasp

It can work perfectly for days, then, during a JT65 TX period, or even just pressing TUNE on PSDR, the output will start oscillating wildely for any length of time, sometimes all the way down to zero, sometimes coming back to full power and hovering at levels in between. I made a videoclip of a typical episode. It´s not SWR (stays at 1 : 1) and I have eliminated software. Running PSDR 2.7.2 and W 10 pro, but it also happens under W 7 on the same PC

Shipping the rig to the USA is all but impossible, and I am trying to fix it myself (I have troubleshot it before, successfully). Any hints that would speed up my work would be greatly appreciated!

Tnx and 73  -
