Wait a minute guys ... SORRY guys!!!!!
?
Using the SA for RF alignment led me astray, .. and you all with me!
Don, you say need education ... from my side I would say I need a medical treatment for my brain!!

We are not looking for the peak at the resonant frequency, as you would do aligning an IF, but we are looking for the MAX at the indicated frequencies. Operating this way the? entire response curve of the band takes on an ideal shape and the peak will be placed approximately in the middle.

This picture sketches what I mean...

Looking that happenin in real time makes things much more clear.
This also explains why the radio is performing well.
?
Still, band 1 & 2 won't get to a MAX at the indicated frequencies.
Releasing the TRIMCAPs from fully tight to fully released the signal (and the entire curve with it) goes always up and never down until the TRIMCAP reaches its end stop.
I would say: they go to "highest possible value"...
