My 32S3 loading control capacitor is fully meshed when loaded up on 30
meters. In looking at the schematic it seems that increasing the
capacity of C-80, 100-500 pf, would help move the loading capacitor from
the fully meshed position. I have been living with this issue for some
time. I have to reduce the drive to maintain proper plate current.
C-80 isn't easy to reach and I suspect it was set at Collins during
construction. Haven't found any information on setting up the loading
assembly on this transmitter. Therefore I have been hesitant in tuning
these capacitors. Any insight in the area would be greatly appreciated.
