This isn't a direct answer to your question, Doug, but if you're looking for a physically small supply, consider the Gamma Research HPS-1a. It has enough current capability for 100-watt transceivers using intermittent duty cycle modes (SSB & CW). It is about the size of a thick pocket book and weighs just over a pound.

Hi all: Wondering if anybody has measured this... I have the K3 with the KPA3, but I run it almost all the time at 5 watts output (5.0 setting). What is the max amps that this configuration might draw, assuming a good SWR and a normal voltage (indoor) supply? I want to see "how small" (but safe) a power supply I can use. Thanks, de Doug KR2Q PS: I already have a 35 amp supply which I'm currently (no pun) using, but it overkill when I run qrp. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
