After talking for a few minutes, I get the following error message on my K3:

ERR 12V

At that point, I cannot key the rig except at low power (5W or so) and
sometimes not at all.

I have to recycle the POWER switch to operate again and the power is dialed
way down.I have to bring it back up to 100W. So far, this has happened only
on 10 meters with the amp on.but I don't know if there is a connection
there. I am using an MFJ-4125 power supply (that may be the issue). I
haven't tried another power supply yet. Anyone else run into this problem?
