Paul,
Your low serial number K3 most likely does not have gold pins on the
front panel to RF board connectors.
You can probably fix it by removing and reseating the front panel
assembly. Some have reported that a small bit of DeOxit will help, but
I cannot personally vouch for that.
If that fixes it, know that you can change the connectors to the gold
ones, or have Elecraft do that for you - contact support for the part
numbers.
If you did not assemble that K3, you can find the front panel removal
instructions in several of the Elecraft documents - one of which is the
K3 Front Panel Modification
http://www.elecraft.com/K3/mods/K3%20Rev%20B%20FP%20Mod%20v1r6.pdf - you
do not have to do the mod, just skip to Section B which covers the front
panel removal and reassembly.
73,

My six year old K3 (#217) has been behaving oddly the past few weeks. The NB
button sometimes doesn't work at all, either short press or press-and-hold, and
sometimes when I press and hold it to bring up the LEVEL settings it behaves as
though I'm pressing SPEED/MIC knob -- i.e., the display will toggle between CW
speed and Mic level. Also, the left side of the BAND and MODE buttons sometimes
do nothing when pressed; the right side of these same buttons continue to work.
There may be other similar problems with other buttons, I can't remember. These
are the two that I notice repeatedly since I change band, mode and NB settings
often. Nothing out of the ordinary triggers this; one minute it works fine, the
next it doesn't.
I can sometimes get the rig to behave normally by cycling the power, other
times by pressing another button that does work. Other times nothing works,
until it just starts acting normally by itself. I've reloaded the latest
revision firmware as well as an older revision from 2010 that I had on my PC.
I've also reloaded old and current configuration files. Goofiness persists.
Could something on the front panel PCB have gone awry on me? I have a KPA500
and a PC connected to the rig, if that is relevant. I've not tried to duplicate
the trouble with everything disconnected yet.
