[Elecraft] [KX3] Boost Buck 13.8 V Regulator

[Jon Moody]

Hi Glenn,

I have purchased both of these DC-DC power converters and have been very
happy with them.  They both have an adjustable output set voltage and seem
to have very good regulation.  The only issue is with RFI that they
generate.  The good news is that they are pretty well shielded in aluminum
cases.   But their is stil some leakage from the power connections but I
have found that attaching good quality ferrite beads on the power
connectors to pretty much eliminate this as well.

YMMV and I am sure that their are many other equally fine Regulators out
there....
