[Elecraft] Switching Power Supply Recommendations Wanted

[Craig D. Smith]

Bob, if you're looking for something to put in a suitcase, I would highly
recommend the Gamma HPS-1.  It is VERY small and light and works well with
the K2 up to 100W.  It is a switching supply with an internal supercap to
handle dynamic loads.  No RF noise that I can hear and also acoustically
quiet.  I really like mine.
