[Elecraft] Who sells a small RF quiet solar charge controller?

[Jim Brown]

Yes. The difference is that the Genesun is an MPPT controller, which 
uses the solar panel(s) far more efficiently, allowing the battery to 
charge faster, but still within the parameters of the chemistry for 
which it was designed. A local ham suggested the Sun Force as a low cost 
option, and it does, indeed, work. And it;s quiet.
