[OZAPRS] VX-7r & OpenTracker +

[Paul]

G'day

being a bit of a new boy to the whole APRS thing, I wonder if I could pick
a few peoples brains with a few questions. I want to setup a
portable/mobile APRS station, mainly for the car, using a Yaesu VX-7R, but
the manual for the radio doesn't show the pinouts for the 4-pin plug. Also
I've been looking at both the TinyTracker 3-4 and the OpenTracker +.
So the qu's I have are;

- does anyone know what the pinouts are for the Yaesu VX-7R.

- where can I get hold of threaded 3.5mm 4-pole plugs (in Oz).

- are there any differences, preferences, strengths or weaknesses with
either the TinyTracker or OpenTracker for mobile/portable operations.

- is it possible to power the TT3-4 or OT+ from the radio or is an
external power source required.

- the vx-7 manual states that the input voltage required for the radio
from the TNC needs to be 5mV at 2k Ohms, does anyone know if either the
TinyTracker or the OpenTracker are adjustable / capable of this.

- or would I be better off just buying a Kenwood D7G hand held.

I was planning to use a GlobalSat BU-303 GPS mouse as the GPS receiver.

Any help would be very appreciated.

Cheers & 73's
Paul
