digital packet in the car

[Jed Parsons <jedp@ilm.com>]

Hi, all,

This is my first post to this list, and I'm very new to the ham radio
scene (still not licensed, in fact :-)  So I apologize in advance for
my newbiquity.

My goal is to get a computer talking AX25 in my car.  This means I
first have to install a computer in my car.  As I see it, there are
two basic ways to go about this:

 1. Use a 300W inverter.  This sounds like a real waste, going from DC 
    to AC and back to DC again.

 2. Run 3.3 and 5 V DC directly into the motherboard, hard drive,
    etc.  This will require regulators and a good filter.  This sounds 
    risky, but way cool.

Can anyone offer any advice about this?

Ultimately, I'll want the radio running as well.  Are there
car-mounted radios, or am I looking at an inverter for that?

(And is this all going to be too much for my sole car battery?  Should 
I be thinking additional battery and batery isolator?)

Many thanks in advance for any help, and any pointers to information.
I still have so many questions...

Cheers,

Jed
