Hi all,
I have had exactly the same problem on my K3 (4520) It is
intermittent and ahs been that way fo a couple of years! Not causing any
operational issues except for 160M AM net when it causes the K3 to drop
back to 5 watts use it to drive a linear with the power out set to
equivalent of 50 Watts.
f the fellows at Elecraft service can shed some light on the
problem I would appreciate any guidance. I have had the 100Watt Pa out
a couple of times but nothing looks untoward.
BTW, I have been having "ERR12V" displayed a few times ! and the
pins for the PA power feed are the gold plated type. Any suggestions or
comments offered will be appreciated.
73,
Eric VK3AX.

Noticed this morning when turning on the K3 for the first time after
being off all night, that the fans were on and changing speed
rapidly. The fan would run between low and the 3rd speed back
and forth.
Checking the PA temp it was jumping from 25C to 60C back and
forth, thus the reason the fans were doing the same. It did this
for about 2 minutes and then went into normal no fan mode.
Anyone had something like this happen? Bad sensor? The radio
had just been turned on so could not have been up to 60C temp
indicated.
Never use more than 35 watts power as I drive an amp all the time,
Thanks 73 Merv K9FD/KH6
