[Lowfer] Operating from 12VDC battery full time.

I suspect that the attached charger will add noise back into the 14v buss.
How about solar panels charging the battery during the day and switched out
at night??? Doesn't Mitch run a solar powered station???

Subject: [Lowfer] Operating from 12VDC battery full time.

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!!!??
