At the ripe old age of nine my K3 developed the ERR 12V problem (in the
middle of a contest, of course). I've seen posts here where owners had some
trepidation about the difficulty of the fix, which is to inspect and
replace some connectors using parts from KPA3CONMDKT.

Relax. It's a bit tedious but it's easy. If you've had any experience at
all with through-hole rework I wouldn't hesitate.

Have a beefy soldering iron handy just in case. Some of the pins were hard
to remove with a small iron. A 40 W iron with 1/4" tip made short work of
them. A circuit board vise or a helper to hold the  KPAIO3 board while you
work on it is also a big plus.

Radio and operator are both happy again.

73 and thanks for listening,
