Bob thank you again for your thoughts. The potentiometer did fail completely so I'm on the hunt fo a 15M linear potentiometer. Best I've found so far is 5M from mouser who should be fine. If anyone out there has another option please let me know.
For now, I had a 10k pot extra from the 2BQ repair that I soldered in today. Relay is back to normal operation for now and not getting stuck. The delay is obviously very quick, essentially QSK between letters. Hope the 5M will be enough range to lengthen the delay a bit more.
Joe ki5o?
