This is a pretty small payload. Quarter shown for scale

Tucked away inside are:

  • Alinco DJ-C5 dual band credit card radio

  • GPS Receiver

  • Basic Stamp Processor

  • TinyTrak 3.0 APRS encoder

The only constant (currently) is the format of the APRS data string.

The originating callsign may change and the message will reflect the flight number and possibly attach point as in the above example where the microAPRS was attached to the balloon envelope to facilitate its recovery.
