[Elecraft] Reliable DC Power Supply for K3/P3

[Phil Hystad]

I use an RS-50M and yes it is indeed a real heavy tank.  But, then again, it sits on the floor, it is not in the way at all, and it is on all the time (except when I am away from the house for more than a couple of days).  I use it to feed a West Mountain Radio Rig Runner 8012.  Perfect set up for my QTH.

I also have the RS-30M which I use as my "portable" power supply.  By portable, I mean portable here at this QTH such as in the garage when doing experiments or building something, out on the back patio when I am operating "remote" in the sun-shine, or sitting (also on the floor) in a convenient location where I use it to drive my Li-ion battery charger.

The RS-50M via the Rig Runner drives about six or seven different rigs -- all plugged into the power (Anderson connectors) but obviously not all on.  I have a variety of 12 volt DC things that came with their own wall wart but I prefer to use them with the Rig Runner so they now all sport Anderson Power Pole connectors.

Each power supply is only capable of powering one of these devices during transmit, but since I don't transmit on multiple radios concurrently, that's not a problem.
