APRS - TinyTrak4 Object Generator

• The picture shows a PIC16F628A-based object generator for the TinyTrak4. Serial data at 9600 baud are fed to the TT4 in TEXT mode. The 2k memory of the PIC16F628A allow at least 20 different APRS objects, items, etc. to be fed to the TT4. This feature is a nice addon for a TT4-based digipeater, allowing the easy broadcasting of HAM-relevant infos on the air.

  

  

  More info (schematic, pcb, assembler and hex files) will follow as the project progresses (2012/Dec/03).

• Two object generators connected to a TinyTrak4 with display.
