I have only Corsair II data and there are no diodes on the counter
board, but a gang of diodes could have been used in the Corsair to
convert band data to binary for the processor. Diodes backwards will
upset that logic.

Apparently not since there are no diodes on the 2's counter board. There
is a single wire band input but I've not been able to trace it. Probably
the BFO, and injection frequency inputs are enough to count the band
