If you are a ham, you can get on the ham bands if you ask for them. The Digital radios of 10 years ago where very good, I've not seen the new stuff since then but I'll bet it's even better/cheaper than it was then.

Look at the ARRL's site for a "well known key". I would strongly suggest going encrypted though, because any fool with a laptop could connect to your system if you don't. (Not that WiFi encryption is all that great to start with.) Frankly, you don't need to go part 97 here unless you intend to use more power than part 15 allows, or you want to use a beam antenna and get more radiated power than part 15 allows. But if you need to power up and cover the whole city for an emergency communications net, go for it.

It shouldn't be any more difficult to wire up than for any other radio. RigBlaster may even have the jumper settings for that particular radio. Send them an e-mail.
