I've got a new Corsair I, new to me that is, and after running a few simple
checks I ran into an unusual problem. On the 80-meter band the output
would drop to a max of 5-watts out at 3650khz and slowly increase as the
frequency went up or down. First I figured it might be the bandpass filter
being misaligned, but not so. I finally went to the RF Mixer board #80987
and checked the LO and TX inputs.....very little change in signal levels at
any tuned frequency. I noticed a tuned trap, at least that is what it
looks like to me, T8 and C1......Can anyone familiar with the Corsair I let
me know what the function of this tuned circuit is??? I turned C1 about
1/20 of a turn and the problem disappeared. Works great now. Thanks
