[Elecraft] [KX3] Hi Curr Warning

[Gary Hawkins]

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,
