My trusty old K3, SN 123 in operation almost daily since late 2007, and has performed almost flawlessly since. It has been updated regularly with most options and could be considered “almost K3S”. It has been back to the mothership once about 10 years ago for a quick fix due to lightning ESD.
Recently though when changing modes from CW to USB/LSB or from DATA to AM it hangs in transmit. A quick press of the “XMIT” button clears the problem and it operates normally after. It doesn’t hang on any other mode switches but if I change bands from a band on CW to a band on USB/LSB it will hang. On two occasions going from DATA to AM it froze completely and wouldn’t respond to any button and had to be powered off at the power supply. Here’s what I have tried so far: 1. Since the “gold pin” mod hasn’t been done, I pulled the front panel, cleaned all the pins and replaced it. No change. 2. After it froze completely the second time, I forced an EEINIT, reloaded a good configuration. No change. So it appears to be a hardware problem. I haven’t contacted Elecraft yet because they seem to be in flux right now due to COVID and the push to get the K4 out the door. Plus, I do have a quick work-around as long as I avoid the total freeze. So if anyone has had a similar problem and solution or could tell me where to look I would appreciate it.
