[Elecraft] [KX3] Hi Curr Warning

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 be reached even 
though everything is OK.
So check the supply voltage if you see High Current indicated - 
especially if operating on an external battery.
