Micro-Trak 300

VHS Products has created the Micro-Trak 300, a 2-meter FM transmitter combined with a TinyTrak 3 controller chip that provides an easy and inexpensive way to build a small APRS tracker. Just plug in a GPS receiver, such as the Byonics GPS1 or GPS2, and track!
  • No need to tie up an expensive radio for APRS tracking

Note: Micro-Trak 300 is a transmitter only. It does not receive radio signals, and therefore may occasionally transmit over other stations. This is normally not a problem due to the power level of the MicroTrak 300.

Note: This transmitter operates on amateur radio frequencies, and requires a valid amateur radio license to use.
