[Elecraft] K3 Power Supply

[Leigh L Klotz, Jr.]

Thom,
I use a Gamma HPS1a sometimes but it can't handle 120W CW sustained, 
more like 80W but can do 100W SSB.  I also use a Group 24 battery with a 
Battery Tender (1.5A) or a 5A solar panel and controller.  The solar 
panel isn't doing as well in the winter.  For the battery route, the A&A 
charger many people like, and it is 5A.   I use Tempest batteries 
because there is a nearby seller and I can avoid shipping.  They are 
sealed and so I don't worry about hydrogen venting.   Many folks like 
rhe golf cart wet cells and keep them outside.
73,
Leigh/WA5ZNU
