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.
