[Elecraft] OT: Popular power supply query

[Jim Brown]

For nearly 8 years, I've powered all my 12VDC ham gear from the biggest 
Costco battery, float-charged by a little 10A switcher that I bought for 
$10 at a hamfest.  When I started doing SO2R several years ago, I added 
a second battery and a second power supply from the same hamfest 
purchase.  Those little switchers were very noisy until I cleaned them 
up with caps and ferrites. A few years ago, I bought a little PowerWerx 
SS30DV 20A switcher to travel with, and fired it up for a while in the 
shack looking for RF trash. I didn't hear any, although my testing was 
not exhaustive.  The batteries cost about $75, and have lasted about 
three years in this service.

I currently own three vintage Astron linear supplies, all of which have 
been reliable, but which I no longer need. I should sell them. :)
