QRP Power Pack for K1 (was Re: [Elecraft] K2 #4334 alive and well!)

[Guido Tedeschi]

Hi Doug,
    the "QRP Power Pack" is the perfect little companion for my K1.
It contains a 12V/1.3Ah gel battery and a voltage/current limited charger
with a DC-DC converter to charge the battery with only a 12V source.
When 12V is supplied to the input jack, the battery is charged and the
output is directly connected to the input with a small relay, when no power
is applied to the input jack, the relay switch the output to the battery.
If it can be interesting, I will publish the schematic diagram on the web...
Ciao and 73
Guido, ik2bcp
