[Elecraft] New 30A power supply on Elecraft order form

[David Inger]

I found this PS very noisy when used portable with the antenna less than 30
ft away.  Birdies (or whatever is the appropriate term) where generated all
across the spectrum from 80-10 meters.  It was so bad I found the PS
unusable.  When I switched to my Samlec 1235, I had no problems.

It seems that switch mode power supplies vary in RFI.  I know of people whol
find the Samlec noisy; mine isn't.  There may be unit-to-unit variations,
due to small differences in components.

I would recommend that anyone interested in this PS should try to use one in
their specific situation .  The Powerwerx unit was quiet on my home station
(antennas are 100 ft. away from the supply), but totally useless for me
when used for "vacation portable."
