Hi Gerry,
The unit does not appear to be hot.

Hi Ron,
Thanks for your response but could you clarify.
On the 12/10m bands I'm not sure of the VSWR of the antenna, but the VSWR
reported by the ATU was 1 to 1, so basically the amp was perfectly matched and
should have been OK. Now the fact that I had the radio set for 10W rather than
8W on 12/10m might be an issue if the KX3 was over driving. However, I'd made
the assumption that the KX3, knowing it's band, would just limit automatically
- that might not have been correct.

Not just "low" antenna impedance, but high SWR. The output stage is less
efficient when the SWR is high so it draws more current to produce the
requested output.

Subject: [Elecraft] [KX3] Hi Curr Warning
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 consists of KX3, with ATU, 1/4 wavelength vertical cut for 20m.
SLA battery, well charged, operating above 12V under load. Antenna fed from
50ft co-axial cable, 30ft counterpoise connected to ground of KX3. TX power
set to 10W
Both times I was operating on 15 or 10m. ATU was tuned, showing 1:1.0
match.
Does anybody have any idea what is causing the HI CURR warning?
After it happens, TX power reduces to 5W. CMP and ALC bars display - no
matter what I do I can't get these indicators to go in favor of SWR and RF.
Even if I power off the KX3 it still comes up in this display mode.
Finally, for no apparent reason, after five to ten minutes it then seems to
switch back to SWR and RF display.
Looking forward to your input,
Gary
