Re: QMX+ Power Output Question
When I did the initial LPF sweeps I noticed that filters were attenuating the signal within some of the bands.? Adjusting the spacing of the turns on the coils made little difference.? Backing off a

Re: RTC battery mistake
The QMX+ operation manual that I saw is for the regular QMX. Do you have access to a different one? For instance, the diagrams of the front and (I think) rear panels are laid out differently. I

Re: QMX+ rev 3 freezes shortly after boot
Michael,
that's a good message. But honestly I have no clue how your work could repair your problem. Maybe during your work you unknowledgeable removed a tiny metal piece.
