[Elecraft] KX1 power supply

[Don Wilhelm]

Ed,

I would be reluctant to run it about the maximum recommended voltage.
It is just a guess, but I think it may be OK if you always have a low 
SWR, but as the SWR increases, the voltages in the PA output circuit can 
increase dramatically and the capacitors in there do not have a lot of 
margin for the peak RF voltages developed.

Here's the question, does it, or will it hurt the KX1 in the long run, running 14.9 volts into the radio, I know the manual says 14 v. Does that .9 v make any difference to the PA, or should I just stick to my 13.8 v and 3 watts ??
