[Elecraft] K3s throwing a "HIGH CURR" error after installing K144XV and Reference Phase Lock Option

[Keith Trinity WE6R]

Probably just need current firmware.
A fully loaded K3 is right on the fringe of triggering the OLD Firmware 
limit of 2 amps.
New FW raises the limit if the HI CUR message.
If you are at current 5.67 FW, then check the actual current being 
drawn, with the internal meter, or a good external one.
You could have an audio chip (U1 on DSP board) going bad and starting to 
draw too much current (if so, catch it before it goes worse and melts 
the board).
If you have a Temp gun or FLIR you could check the temp of that chip, 
take the cover off, and it is at the top front of the DSP board.
