Device Overview and Specifications

• The RTrak-Lite is the only model in the RTrak family that does NOT have an

internal radio/transmitter. The RTrak-Lite requires the end user to interface it to

any VHF/UHF FM radio of their choice. The main advantage to this is the ability

to use a radio with any transmitting power level and have an internal receiver to

check for channel activity before transmitting.

OpenTracker 1+: The data modem section of the RTrak-Lite is based on the SMT

OpenTracker 1+ platform. The OpenTracker was designed and

programmed by Scott Miller N1VG of Argent Data Systems. The

OT1+ platform is fully open source and a perfect match for the

RTrak-Lite tracker. Firmware upgrades are free for download.

M%5010HS: The GPS receiving chipset used in the RTrak-Lite. This GPS is a

Sirf-Star III receiver with a fast <60 sec cold start lock time,

measures only 10mm x 10mm in size and runs on a 5V operating

voltage.
