Thanks for all the suggestions. I went all around tapping all connectors
and filters. I ran all the switches up and down. I got it back,
when I put the filter switch back into the stock filter position.
Don't know whether it was a filter, connection, switch, or even if I
somehow left the filter switch in an open position (no accessory
filters on board). I can test that theory by listening for a
signal with the switch in a position with no filter and see if I
hear anything and get no PBT action. Hey, but then I would feel
stupid. Guess I'll leave it alone. Anyway, the Corsair II works
now.
Next topic: I want CW filters for it! Anyone have the 282 or 285
(6.3 MHz IF Cw filters, 500 and 250 Hz) for sale? I would buy or
have a 9 MHz IF filter to trade, the 218, 1.8 Khz ssb filter.
Anyone ever build on an added filter into the 9 MHz IF for the
Corsairs? I was thinking of adding a 500 Hz filter in that
IF automatically switched in by the CW mode switch or manually
from a switch on the back of the rig. Would be nice to have a
pair of 500 Hz filters for normal CW operation.
Thanks to everyone for the help. I got a lot of good solid advice.
