[Elecraft] X-Dragon 20W Solar Panel

[Fred Jensen]

I do.  K2/10 when in the field, also at home to charge LiFePO4 when I 
can't take the panel.  Mine was a gift [from KD5KC], he acquired 
several, I think taken out of oil field service.  Charge controller, I 
replaced the 5 Ah SLAB, I measure 1.1 A short-circuit, but it was on a 
partly sunny day and the panel-sun line wasn't normal to the panel. 
Assembly is too heavy for hiking, but great when I have the truck.

I have discharged and charged the SLAB [and my LiFePO4] enough times 
that I believe nearly all the electrons are green.  Admittedly, there 
could be a few brown ones left, but they're at the bottom and I never 
discharge either that far. :-)  I thus enter field contests [next is 
QRPTTF this weekend] in the green power class.
