Re: synchronous interface card suggestions

It's licensed equipment currently in the 950MHz range that we are converting to operate in the US amateur band between 902-928MHz. We're licensed hams and plan to use the radios for digital voice and data links between remote sites.

I'm working with what the radios support -- which is synchronous RS-422.
These are some surplus radios that  have quite a bit more range than
802.11b (though they're not nearly as fast).  They are 5 watt output,
full  duplex narrowband radios that were spec'd for paths of up to 30
miles.  We  need the range and reliability more than the speed...

Err, excuse my curiosity, but what kind of radios are these ?

I mean, is it some-licensed-stuff-you-have-good-reasons-to-use, or is
it a hack, or is it plain illegal ?

5W looks rather powerful for unlicensed spectrum...
