[OZAPRS] Running aprs in the car with a laptop

[Alan Wallace (ZL1AMW)]

I run a Compaq laptop from the car's 12v with no problems.  Just threw
away the (mostly defunct) cells in the battery box, and ran a wire out
the front.

I actually have an auxiliary battery in the boot, which runs the APRS
gear. This is parallel-connected to the car battery when the engine is
running.

This means I have a power source that can go flat (if I leave things
switched on to long when parked) without compromising getting home, but
that is charged when the car is travelling.

Some further info (in case you may be interested) - I run UI-View on the
laptop, with a Paccom pico-packet TNC, and when the programme exits it
sets up the TNC as a basic tracker, when the PC is running it uses the
TNC as a modem.  Quite handy so I can boot up the laptop on longer
trips, but use the tracker-only on round-town driving.

And I have a 12v laptop which refuses to run on the 13.8v in a car...
