Hi Larry,
Please review the following video.? It is for the QCX+, not the QMX.? The principle applies.? You what to try adjusting the LPF inductors to see if you can optimize the power out:
There is no class E amp in the QDX (the QDX is class D), so ignore the first part on adjusting L3.? The QMX uses 5 pole filters, so only two inductors can be adjusted.? The other point is that the LPF is shared for one or more bands.? You may have to choose between bands or find the middle power output.? The example is 20 and 30 Meters share the same LPF.? You can optimize for 20 or 30 or find the midpoint between the two.
