So if he was not run off from all of the Social media vs email list stuff. Sherman W4ATL joined the list to answer any Data Radio questions. Sherman was the chief engineer at DR when I was there. His knowledge is going to be pre-cal amp take over. So any of the current off the shelf stuff is going to use proprietary information that I doubt Cal-Amp will publish. Even the older stuff uses proprietary code mmunitariona protocals, but the ability to hack these is likely as they are just Z80 processors. So Sherman if your still here and are willing to answer any questions go for it....

I wonder if the 900 MHz model (928-960 MHz) can some how be made to work in the ham band (902-928) ? Or is there some sort of filter that is going to pretty much prevent that.
Reason I ask is there are a couple of the 900 MHz ones on Ebay at a sane price. (CALAMP VIPER SC+ 900)

The 800 and 900 base stations are just Tait base stations with 2rx so they can be moved easily to the 900mhz ham band. This has been done several times. Y the 900mhz guys. The Gemini mobiles are going to be rare. Cox cable used a bunch of the Mobile packs on 900mhz in NOLA and other markets, but these are just tait mobiles w/o a head. Easily programmed with tait software.
