about that - the email was originally intended for Terry
WA0ITP, regarding his article in the latest "Banner" on
wall warts for "Motel" power supplies. I forgot to
include the URL when I told him about an inexpensive, RF
quiet switcher that puts out 13.8-14 volts at 2.5 to 3
amps. It's designed as a replacement supply for ACER
and Samsung monitors and Amazon has them for $9.99 plus
one to with my KX3 when I'm close to AC power and it
worked so well I picked up another one for a spare.
They are spec'd at 14 volts output but both the ones I
got measure 13.8 volts which is pretty much the design
voltage on just about every QRP rig that runs on a
nominal 12 volts anyway. They are over voltage, over
current protected and cheap enough that buying one might
even be cheaper than a wall wart plus the 7812 regulator
if you don't already have such in your "junque box".
