TinyTrack

Original TinyTrack by BYONICS
TinyTrack and GARMIN eMap.
TT is mounted in a metal housing with 7 x 5,2 x 4cm. On the front you can see the four status LED's and the two switches for power and for switching between the two settings.
TinyTrack is originally developed by Byon Gabarrant N6BG. You can find more info about / buy it at BYONICS. BYONICS delivers normally within 4-5days (also to Europe). Distributor for Europe is WIMO.
  • Support for SmartBeaconing, with corner-pegging, as used in the HamHUD.
  • Support for GPS time slotting for transmission times.
  • Can transmit position in MIC-E, or ASCII text format.
  • Transmits altitude information.
  • Transmits at a user set rate with 1 second resolution.
  • Two configurations, with all user options switchable.
  • Optional transmit holdoff when GPS position is invalid (satellites not locked).
  • Optional force MIC-E format to all printable ASCII characters.
  • Can send a status/comment beacon, even when not sending position information.
  • More user memory for longer status/comment messages.

 I'm using the TinyTrack now since October 2000 without any problems for mobile operation in my car. I use it in combination with a modified DeLorme Tripmate GPS Receiver and a YS-130 2m TRX from DRAGON with 50W on 2m. (for normal use the 10W low power is enough). The YS-130 is mounted in the back of the car and is switched on/off via a 12V electronic power relay controlled by the TinyTrack.

Backside of the housing with the two 9pin SUB-D for GPS in / PC config and TRX data in/out (GND,MIC,PTT,Speaker,+12V for TT/GPS and +Ub for the RIG-Relay on/off).

Top Layer View Modifications I made:
  • Male 9pin SUB-D connector to connect Null-Modem cable/GPS directly.
  • Power supply to GPS via pin9 of SUB-D.
  • 5V/1A power regulator.
  • switch between 5V/12V power supply for GPS.
  • Electronic 500mA fuse for TinyTrack.
  • Additional 100uF capacity for power stabilization.
  • Data filter for serial in/out.
  • 10MHz X-Tal instead of ceramic resonator.
  • Double side PCB (from PCB-POOL).
