The pair of Ritron DTXM-254's arrived today. Can't wait to reverse engineer them. The first thing that was done was to TAKE THEM APART! Here is what was found:

Ritron Radio Mods

The processor is an Atmega32 which has more I/O pins and more memory than the Atmega8. This is the central processing unit for this radio. Next to it is the MX919B which is a 4-Level Root Raised Cosine FSK Modem. This is the little guy that does most of the talking. A fine engineering job well done by Ritron.
