Hello all, I've just acquired a secondhand QMX. It's in mint condition, has a Rev 4 PCB, and was factory built (supposedly). It works perfectly fine, but the X502 jack appears to be very slightly

Re: QMX+ over-voltqge?
Thanks, Chuck. I’ve tried many variations, factory reset, restarts, using SWR meter and dummy load, so no high SWR concerns. Still no output or input. I’ll work on it some more and see what
