PLL Chart for this exciter

[Shedbuilt]

The board in subject, looks to have a single tuned doubler. His old boards definitely did, and the oscillator was Clapp - rather than the more common Colpitts topology. Still oscillator, buffer, doubler, final.

Was it not something like
all switch of 87,50
and then
0,1-0,2-0,4-0,8-1,6-3,2-6,4-12,8
for switch
1 2 3 4 5 6 7 8

so if you want the pll on 94.2
94,2 - 87,5 =6,7 so switch 7 and 1 and 2 must be on

The boss knows.
