Sorry about the empty message. Not sure what happened.
Wanted to close the loop on this. Thanks to those that responded off-list.
I was running MCU 1.57 firmware which is where I was seeing high current
warnings. I hadn't noticed the changes in MCU 1.61 but just upgraded to
MCU 1.79 and
Similar issue here for a while.
When I first built the KX3 it calibrated out using the KX3 utility
fine. Several months later (Summer 2013) I was at the bench and re-ran
the calibrations using a power supply and dummy load. Cal failed on 10m
with High Current. I upgraded firmware and

Hi Mark,
I have revision C2 of the manual and, if I remember correctly,
theimportant power voltage setting is 11V for full power. Thatbeing
said, if 13.8V is what is required this may explain what'sgoing on.
The SLA nominal voltage is marginal. I'm going

The KX3 and all other Elecraft transceivers that use a similar power
control mechanism will attempt to maintain the requested power output.
If the power supply voltage drops, the current must increase to maintain
the requested power output.
That often means that the High Current threshold will

Hi Gary
current is required. So lower voltage
supplies bring you closer to a HI CURR situation.

Gary,I didn't find the table, but I did find two relevant posts:
This was the problem reported by one poster:
During xmit at modest power 8 - 9 watts, I occasionally see a msg flash on
the display that shows hi curr. It seems that when that happens, the xmit
power gets reset to 5.0 watts. I

On my last two SOTA outings I've experienced HI CURR warning with the
KX3. I've read this is associated with low battery voltage or low
antenna impedance. I think at one time there was also a software bug
associated with specific settings that was fixed with a firmware release.
My setup
Hi Gary,
The maximum specified output power of the KX3 is 8 Watts on 12, 10 and 6 meters
(I think so).
This would explain folding back on 10 but not on 15 meters and certainly does
not explain the display issue.
Greetings
