VE7GDH Micro-Trak 300




Micro-Trak 300

The Micro-Trak 300 by VHS Products is available from It is a 300 mW transmitter operating on 144.390 MHz with embedded TinyTrak 3. The early versions came with the SMT version of the TT3. Newer ones use a regular PIC16F628 right on the Micro-Trak circuit board, the same as is used in a TT3. You supply an enclosure, antenna, batteries and connect a GPS. I intend to mount one on my mountain bike and see if the 300 mW signal is enough to provide decent coverage.
