[Elecraft] Using the KX1 on Solar Power

[Don Brown]

Hi

I have not done this with a KX1 but it should be easy. An 8 or 10 cell set 
of NiMH batteries would work on a small solar panel. You would need to size 
the panel to fit the approximate 1/10C charge rate for the cells and connect 
the panel through a blocking diode directly to the battery. You would then 
connect another set of wires to the battery to power the KX1. A set of 
1800-2500 mA Hr batteries would work with a 3 to 5 watt panel. The 
Volkswagen panels that show up on EBay at about 170 mA would work without 
needing a charge controller. NiMH batteries can be charged at 1/10C almost 
indefinitely without damage.  If you are going to use a SLA battery then you 
will need a controller or you will need to monitor the voltage carefully so 
you do not overcharge the battery. You can use one of my charge controller 
kits with a small 2-3 amp Sealed lead acid battery. The controller kit is 
$30 check or money order from.
