Hi.
As a ham radio man, I am hoping you can help me out. I have a DX394
receiver
and usually use ac to power it. I can run from a car battery, with
the
adaptor. It requires 12 volts at 500 Ma. What I am wondering is if I
can
build an emergency power supply so I can listen using batteries when
the
trees take out the power lines s.


The DX-394 draws from 170 to 200 mA, not 500 mA, so any 12V battery
capable of a few hundred mA-hours will be able to run it. The larger
the ampere-hour capacity, the longer it will run without recharging.

For lots of info on the DX-394, consider joining the group
http://groups.yahoo.com/group/RADIOSHACKDX394/ (at the moment, Yahoo
seems to have a serious problem and nothing can be found on the group
website but it should be restored soon.)
