I can quite easily set up a sweep in QMX based on power output measurement. Everything interacts with everything. I don't think you can make too many assumptions about symmetric BPF sweep etc. So it'll be just a "for what it's worth" indicative kind of a sweep. Best we can do...
FYI yesterday I got Power and SWR working nicely on my QMX. I added it to the diagnostics screen in the terminal. And also the LCD during transmit. It shows both power out and SWR in the 3 LCD characters between the mode indicator and battery voltage icon. Power is 0 to 6W full scale deflection whereas SWR shows 1.0 to 4.0 with each "bar" worth 0.2. I also added a configurable SWR protection feature.

Hello Hans,
Thank you for the response.
For the current QMX, using the unused 0 BPF selection on IC402 might be possible.? That could be set up with jumpers to bypass the BPF.? That does take up one of the BPF selections.? Is it possible to factor in the BPF response based on the assumption that the lower half of the frequency response is the same as the upper half?? That could be factored into the measurements.? I am unsure if that would be accurate enough for adjustments.
It was just a suggestion and at a much lower priority than anything on your current list.
