They use proprietary modulation so ham radio wise they are out. They made some 900mhz telemetry radios. Of course you could go direct to the radio board and modulate. I have the key that decides the band splits, and I am happy to decode radios, but I can't give the spreadsheet out.
Lin Ps should have a pretty standard GPS inside that can be used and programming is not impossible you need a program called DMP demo

Lin,
Some time back I picked up a pair of Gemini G3 Dataradios on ebay, hoping to be able to use them. I quickly learned they really cannot be used point to point, and you need the expensive base station to act as a controller between them.
I swear I have read that some models of the radios are capable of point to point/ peer to peer use. Do you or anyone else know which models would be good candidates for such a thing?
I ended up giving them to a friend who documented them the best he could:
