[Elecraft] K3 Quickest way to access loose AUX RF nut *TIME CRITICAL*

[Erik Basilier]

Ron, I know what you are referring to. During my aborted attempt I first
removed the long screw, but gave up when I realized that I was up against
the voltage regulators. I put the screws back and packed the radio in a
case. Question: does this mean that I have some loose hardware now relating
to the standoff at the KAT3? The long screw seemed to tighten ok. In other
words, should I open the radio and follow your instructions, or can I be
reasonable confident and be on my way to FD? This is time critical.
Thanks,
Erik

There are two additional complications to removing the right side panel. 

1) The top rear screw that secures the panel goes into a 2D fastener, just
like the other corner screws, but it's an extra long screw that goes all the
way through the 2D fastener and into a threaded standoff that is used to
secure the KAT3 or KANT3 board. To replace it correctly so the standoff is
tight against the 2D fastener, you need to:

 --Remove the mounting screw and lock washer holding the KAT3 or KANT3
board.
 --Replace the side panel and tighten the long screw in the 2D fastener.
 --Tighten the standoff against the 2D fastener.
 --Replace the KAT3 or KANT3 board mounting screw and lock washer.

2) The second issue is that there are two screws and nuts mounting two
voltage regulators, U12 and U14 on the side panel for heat sinking. They
must be removed *before* trying to remove the side panel. That's not too
hard if there is no KRX3 sub receiver installed (be aware there are lock
washers and nuts on those screws that must be removed and replaced). If the
sub-receiver is installed you must pull the sub-receiver module out of the
K3 to get to them.

That's why I suggested going in through the rear.

I just swapped the sub rx from one K3 to another. With the right side panel
removed, the aux BNC is right there and you can use a small 7/16 open-end
wrench to tighten the nut.
