[Elecraft] Yet Another KPA500 Question

[Don Wilhelm]

Bill,
I don't know about "faster switching", but normally in a T/R switch, the 
diodes must be reverse biased with a DC voltage higher than the peak RF 
voltage to be encountered.

My guess would be that it maybe used for the T/R swithching and the higher voltage insures faster switching but that is just a guess.  Don or anyone do you know?
