[Elecraft] OT: wall wart for RX-only PS?

[Brian Machesney]

Doug,

Many (most?) wall warts are unregulated. They may present a much higher
voltage than the indicated output when they are not under load. I recommend
you check the no-load voltage to be sure you don't fry something in the
FT817. You could, of course, put enough resistive load across the output of
the 'wart to bring the voltage into a "safe" range when the radio is off.
