[Elecraft] [KX3] Hi Curr Warning

[Ralf Wilhelm]

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

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.
