The Texas Packet Radio Society did a conversion for the RCA 500 UHF mobile
radio for 9600 Baud packet back in the '80s. They had a very large network of
radios covering most of Texas with the RCA radios used as the backbone. It was
a pretty simple conversion as I recall, to do direct FM in the transmitter and
recover the 9600 Baud data from the receiver.
I don't know if any of the conversion info was ever on line, but a search of
the TAPR site might find some of the info on that conversion.
The big problem these days is that most of the radios were scrapped years ago
and are no longer available.
I have a buddy - N0IA (N0IA at WINLINK dot ORG) who converts the GE Rangr 440
radios for 9600 Baud operation, but I don't know how extensive the conversion
is. It may involve changing out the receive filters to allow enough bandwidth
to pass the 9600 Baud data.

Would like to hear from those that have converted OR can suggest a
radio either 2m or 70cm that can do 9600 baud digital "Packet".
These will be put at remote hill tops to provide a backbone system for passing
large volumes of data. I appreciate your time and trouble.
Thank you
