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.

<> Hi Elecrafters,

<> I just sold my big, heavy linear power supply to replace it with

<> with my K2/100. Looking at the eham.net reviews, comments on all of the
<> switching supplies seem to range from "great, absolutely no switching

<> Thanks.
