I have posted an album of photos of my standalone tracker based on the Argent Data T2-301. Look in the Photos section of this forum for an album named "Standalone APRS unit based on T2-301".
The parts used were: Argent Data T2-301 Argent Data GT-525 GPS Receiver Pelican 1030 case 8 AA cell battery pack from Batteryspace.com Energizer Lithium AA cells Suction cup handle from Grainger 5/8 wave 2m rubber duck antenna from Smiley Antenna BNC male to male and female to female adapters DB-9 male connector Conduit clamp 3/8" id rubber grommet I cut out part of the vinyl insert that comes with the Pelican case in order to clear the BNC adapter and GPS receiver. The rim of this insert needs to be left in place to maintain the gasket between the case and lid. The GPS receiver was hot-glued to the inside of the case. I drilled the hole for the BNC adapter with an Irwin step drill. Since the wall of the case is too thick for the groove on the grommet, the step drill let me make a counter-bored hole so the grommet would fit properly in the hole. The photo of the unit mounted on the vehicle shows the original orientation of the case to the handle. I found that the window of my Ford Expedition curves too much for the handle to sit flat, so I turned the handle 90 degrees in relation to the case. This unit was successfully used on the Indianapolis Tour de Cure bicycle ride earlier this month to keep track of one of the SAG vehicles.
