[Elecraft] kpa 100 PA hot ??? & no power out

[Douglas Westover]

Hi Bill,

Check the value in the menu item "CAL tPA", I'll bet it says
256. There seems to be a mysterious set of circumstances
that causes this value to be set to the maximum value.
I've had this occur on several occasions and the solution
is to reset the CAL tPA value.

73 and good luck,
Doug, W6JD
K2/100 #1626
