[Elecraft] Ideal input voltage for TX on KXPA100?

[Don Wilhelm]

David,

Be careful about checking for 13.8 under load because you don't yet know 
how much voltage drop you have in the power cable.
Check the difference between load and idle at whatever voltage you have 
right now.
You MUST keep the maximum supply voltage to less than 15 volts.

What I am saying is that if you have significant voltage drop in the 
power cable, then setting the voltage under load to 13.8 *may* result in 
greater than 15 volts no load.

If you have significant voltage drop in the power supply to KXPA100 
power routing, fix that first.
