[Lowfer] Operating from 12VDC battery full time.

[Les Rayburn]

Tonight I was testing my new set up for emergency operation preparing for 
an upcoming
MARS net. I've just purchased a large, deep cycle marine battery for 
powering the
shack. Made up some cables with quick disconnect fuses, etc.

When I switched from the power supply to the battery the noise floor on 518khz
the noise floor dropped quite a bit! Tuning around a bit, I was really 
surprised, considering
that I use a very large, (non-switching) type power supply, with lots of 
filtering...the
AC is filter and conditioned, etc. But there was the proof, a much quieter 
receiver.

Now my mind is racing at the possibilities for improved weak signal 
reception. I have
also purchased a plastic marine box and automatic charger, which I had planned
to install just outside the shack window so that the battery could be kept in
a fully charged condition.

My question now is, is it possible to operate the station from the battery 
full time,
with the charger connected and protected, perhaps by diodes or something?
Have others tried this!!!??
