APRS - LX3PR
Yaesu FT-1500M, Diamond X-50N, TinyTrak4 with display
The TinyTrak4 is configured as a stand-alone wide1 fill-in digi. Configuration can be changed
by an attached PS2 keyboard. The RS-232 port can be used for connecting a GPS or weather station,
a computer for programming and back-up (currently done with an old HP 200LX DOS palmtop). The port
can also be configured to act as a KISS TNC interface. Another interesting feature is the APRS
TinyTrak4. Pictures show the built and the kit version.
One is not enough, you need at least three!
BYONICS Micro-Trak AIO, a 10 Watt (when powered with
13.8 VDC, 3 Watt with 8 NiMH) all-in-one portable tracker, with built-in
GPS, APRS encoder (a Tiny-Trak 3 chip), transmitter and power supply.
Just switch it on and your position is on air (but don't forget the
non pictured antenna ...). Available at byonics.com
TinyTrak 3, no longer used for tracking. The controller
chip has been changed to a "tinypack" chip. Currently I am experimenting
to send APRS packets via an HP48 calculator. It is planned to build
a semi-automatic weather-station, by entering weather data into the
calculator, who then transmits them via the TinyPack connected to
The kit is very easy to build and well documented. Parts available at byonics.com
