Well, If you look long enough, ya can find anything!
Once I got the keyer working properly, I evaluated the interconnecting
cable between the PS & RF deck.
This cable carries AF from the driver, & the "hot" side of the CW key input, down to a
relay....In standby, the relay is open, and B+, AF, and the key line is open.
So....
the keyer circuit was sick
the cable was bad
AND one of the 4 contacts of the relay was touching all the time...it just happened to be
the key line contacts!
WOW, lot o work for just a small problem...
