APRS Tracker Box KI6IUCCheck out the APRS tracker box I just built. This box hooks to 12 volts, an antenna, and a GPS puck. It transmits it’s location on programmed intervals through the radio to digipeaters in my area. These digis then transmit my location information to the internet. Check out

I wanted the box to be as small as possible, so I ordered two sizes. The smallest one they had and the next size up. I used the tiny 9″ x 8″ x 4″ box. A bit of a squeeze, but it’s all in there. It’s a good thing you can take off the HTX-202’s battery. The idea is: I can throw this unit in any vehicle (car, truck, rally car, etc.) and track it from space. :)

The Byonics TinyTrak TNC with GPS receiver is around $120 with cables. The radio was $55 used on eBay and the connectors were found at the local electronics store and a swap meet. The powerpole chassis mount is wired up in series so that other hardware can be powered and either connection can be used.
