Well, we thought it couldn't be done, and we were wrong. After a lot of discussion and work Ric Plummer, KV1W has made it happen. I had the pleasure of assisting him with testing and encouragement and it works great. I have this installed in my truck and used it all day today with no problems.
The basics are that he took an RS232 TTL converter and an Arduino processor to translate the headers from the BCD996P2 datastream and make it read as a BCD996XT. Since the rest of the command set is the same the converter works great. It connects to the rear GPS port of the BCD996P2 so there is no surgery required on the radio or the RH96. You get all the wholesome goodness of the 996P2 working on an RH96.
The complete plans, schematic and programming can be found at www.n9jig.com/radio/RH96_for_the_BCD996P2.pdf
Enjoy!
