Re: #qmx Antenna Tuner Can Kill PAs #qmx
Unfortunately, as Allison is all too aware since he's a seasoned user of this group, this is too true. I've seen a months discussion and 200+ posts on a subject that ends in a solution. And then the

Re: QDX Rev 4 Only Shows 80M Band After Working Near T2
I downgraded my Rev 4 to 1.07 and all bands are back.? Previously I only saw 1 band.? I'll check the voltages, but I may do nothing if all bands work as before on 1.07.

Re: #qmx Antenna Tuner Can Kill PAs #qmx
The QMX hardware already has the capability of modulating the amplitude of the output. Now it’s just a question of Hans getting a Round Tuit. Not like he has anything else to do. ? 73, Willie

Re: #qmx Antenna Tuner Can Kill PAs #qmx
Just a thought. Hows about creating an external high/low power switch in line with the DC cord ? It could switch between say 7.5v and 12v (or what ever, using either a fixed voltage regulator(s) or

Re: QMX pre-flight check - incipient Q103 / Q104 short in buck regulator
Steve, Before surgery, I would try to move Q103 a little by heating up the Tab until the solder melts and push Q103 over a little by inserting a small flat blade screwdriver between the bodies of

Re: QMX pre-flight check - incipient Q103 / Q104 short in buck regulator
On second thought, I think the better solution is to go ahead and shave off the part of the Q104 pad that extends under Q103, and externally complete that net with a jumper wire. Less risk of a short

Re: QMX Board pinout vs schematic and PSU voltages
Thanks Hans. With the SMPS boards removed I have a short between Vdd and GND which wasn't there before I powered up having checked continuity on the SMPS headers. Does this mean the MCU is dead?
