[Elecraft] K3 - front panel issue
I just noticed that after a fun and uneventful (no failures) weekend of ARRL SS CW one of my K3s has developed a strange symptom. I have done nothing other than turn the K3 off last night and then on this morning. Perhaps I pushed something by mistake, but I have no idea what that could have been. I have turned the K3 off/on but have not yet done a CPU reset. K3# 1193 Running: 2.46 code The following buttons are failing and the others seem to be working fine. Failing buttons: Band / Mode: the right side of the buttons don't work MODE (the up side) - down works fine TEST - does not function BAND (the up side) - down works fine QSK - does not work Other buttons: SPOT/PITCH - no impact to either function NR/ADJ - no impact when pushed RATE/LOCK - neither function works ANT - locked on Ant 1, will not select Ant 2 Anyone have any suggestions???

[Elecraft] K3 - front panel issue (update)
UPDATE: I did a CPU reset (NORM / POWER ON) and the first time nothing changed. The second time the RATE button worked once. Then no others worked, nor did the RATE. So, I did a third RESET - and now everything is working. Before doing the reset I saved my configuration and then reloaded it. Everything still is working. However - - When doing the resets at NO TIME did the EE INIT message get displayed on the front panel. Strange - but working. Now.. Should I load the latest version of microcode.or wait a couple days to see if the problem(s) come back? I am waiting.. 73, Bruce - N1LN K3 # 1062 K3 # 1193 _ From: Bruce Meier [mailto:[EMAIL PROTECTED] Sent: Monday, November 03, 2008 13:41 PM To: 'elecraft@mailman.qth.net' Subject: K3 - front panel issue I just noticed that after a fun and uneventful (no failures) weekend of ARRL SS CW one of my K3s has developed a strange symptom.

Re: [Elecraft] K3 - front panel issue
Ouch. Did you have an electrostatic event? All those buttons have one thing in common: They are using the signal SCANADC1 which is routed to input X3 on the HC4051 analog multiplexer chip U3 (front panel sheet 7). I hope this is not the case, but if that input is zapped, you will have the symptoms you see.
