Re: QMX High Band - No RF

Hi Jim, I had same problem that you describe. Here solution was just turning off the Practice Mode. Hope it's as easy solution for you too. BEST 73 DE DJ1TF - Thomas Am Do., 11. Jan. 2024 um 19:18?Uhr schrieb Jim Bennett / K7TXA via <w6jhb= [email protected]>:
Starting a new thread on this one, as it appears that the slight damage to the corner of the PS board causes no problems. So, my high band QMX, Rev 2, built for 12v powers up just fine. Using Putty, all controls are fully functional. But, I get no RF output and the SWR protection kicks in immediately. Using a verified, short cable of RG-8x to a 50 ohm dummy load.?
?Using Putty I did an SWR sweep and on 20 meters it isn't looking very pretty:

?Other bands show similar, nasty results.
Back in Putty, the "P" button in the transmitter diagnostic portion gives me 30.6 ma current draw. When I press "T", I get red for RF output and 0.0 watts. Voltage goes from resting at 0.6 v up to 9.8 volts.
Where would be some good starting points to check? I've made sure there are no shorts anywhere, and I didn't see any missed or cold solder connections.
