[Elecraft] Power supply for KX3

[KD4IZ]

Paul,

The Astron is a real workhorse and a keeper if in good shape.
If you must go light/small and are just powering the KX3, I would point you to Howie’s (ProAudio Engineering  Kx33) power brick. It is nominally a 4A supply in same form as the laptop power supplies. Mine is quiet and a solid performer.
That being said, I have the Powerwerx unit as well, not bad, but mine does create some low level RFI and fan noise both of which can be dealt with.
If you are hooking up more than one piece of gear like the PX3 and other “stuff”, keep the Astron.

At the same time I will be reducing the footprint of all of my accumulated gear including my ancient, but still working, Astron RS-35A power supply.  Elecraft offers a little switcher made by Powerwerx for $119, and for convince I might just go ahead and add that to my KX3 order, but I thought that I would first ask if any of you have other (better? less expensive?) suggestions for a switching power supply to run the KX3 on?  BTW, I’m strictly a QRP/CW op so there will be no future plans for an amplifier.
