[Elecraft] K3S QST Article

[Kevin]

The cause for this is the use of 12V finals. It would be much improved 
by moving to 24 or 50V finals.

Move the /K3s II/ to 50V finals, say a pair of MRF 150's, limited to 150 
or 200W max output. Design/Sell an outboard 50V switching supply capable 
of 15-20A continuous current, with a 10A 12V switcher built in for the 
rest of the radio.
