Thanks for all the suggestions on getting my K2 back up again. I was modifying P4 on the K2 Control Board to prepare it for the KPA100. My K2 quit functioning in the process.
It turned out that pin 1 on the U6 40 pin socket was defective. On inspection I noticed that pin 1 was missing one of the two contacts that squeeze together to hold the chip pin. All this time, pin was only connecting on one side. After five years of use, all it took was a handling the Control Board to cause a failure. It wasn't a routine handling of the board, but the removal of P4 pin in preparation for interfacing to the KPA100. That did stress the board a bit. I didn't build this K2 or any other, so it was a real learning experience troubleshooting the problem. Its been nearly 20 years since I've been a bench technician, but some of the instinct came back to me. Right now I am recalibrating the K2, since I did a master reset in a moment of frustration. Don Wilhelm is advising with me. Kudos to Don for his help and patience. 73, Steve N6VL _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
