Hi-
I have a Ten Tec Corsair II that has some AGC and S meter problems:
AGC toggle switch has no effect at off or slow. At fast it will cycle from no
signal to pinned S meter then de-sensed fully and repeat at 5 second intervals
with a strong signal. Distorted audio with the same strong signal input.
On the IF/AF board, number 80984- the 10K pot labeled R1 on the board looks
like R59 on the schematic. It should adjust the S meter. The pot. is located on
the board about half way across and away from the front panel on the bottom of
the rig. On the schematic it is located near the left edge and midway up the
schematic. The part measures about 8 Volts on all terminals. It also measures
the variable resistance that it should. It has no effect when adjusted fully.
I wonder if different rigs may have different IF/AF boards with different
schematics relative to manufacturing dates. Mine is 02739.
Any ideas or suggestions?
