[Elecraft] [KX3] Boost Buck 13.8 V Regulator

[Don Nelson]

Glen,

There a number of down converters from which you could choose to run the 
KX3 off of a higher supply voltage - and they are inexpensive. Below is 
the ebay listing for one such device. I have this one on order to test. 
I have yet to get it and can not validate it yet. Do note that the 
output voltage has to be 1.5 volts below the input voltage. Most 
important will be the RFI it may generate.

Don, N0YE
