[Elecraft] KX3 Travel Power Supply

[Keith D Jones]

I got a Sola SCP30 S12B-DN power supply on Ebay – bid $24 on $30 ask and won
it with free shipping.  I cut off an extension cord and wired that into the
AC and put a pigtail with powerpoles and in-line fuse on the DC side.  Gives
out 11.85V (rated 12V/2.5A).  Hooked it up to the KX3 and I could get 10W
out with voltage dropping to no lower than 11.5V.  Best thing is that it
seems to be very quiet, no difference between shack PS, shack battery
backup, or KX3 internal batteries – watching the S meter on HDSDR.

 

I had hoped that I could adjust the output to be able to charge the internal
batteries, but it seems to be potted and sealed.

 

Nice unit, made in Germany, weighs a bit over ½ lb.
