Once again, very many thanks to all who have taken the time to respond
to my posting about the Corsair II keyer problem.
I had not realise that Ten Tec prefer not to answer technical questions
via email (ie without the rig in front of them). Fair enough, I guess.
But they have been kind enough to reply with a suggestion I check the
zener diodes across the keying lines, which I will do (along with the
2.2uF capacitor across the re-set line). Otherwise, it looks like I may
have to think about a replacement chip at $50 (+ $15 postage)!
If I find the solution to the problem I'll post the details here.
Thank you again ..
