FCC Wants Proposals To Manage White Space Database
kdawson writes "A year after voting unanimously to open 'white space' frequencies for unlicensed use, the FCC has now issued a public notice seeking database proposals (PDF). Howard Feld explains in his blog posting: 'At last! We can get moving on this again, and hopefully move forward on the most promising "disruptive" technology currently in the hopper. And move we are, in a very peculiar fashion. Rather than resolve the outstanding questions about how the database provider will collect money, operate the database, or whether the database will be exclusive or non-exclusive, the Public Notice asks would-be database managers to submit proposals that would cover these issues. ... I label this approach "good, but weird."'"
DX/Skip interference like 27MHz does
Ionospheric propagation is a feature, not a bug. In fact it would be interesting to see what could be done below 30Mhz with protocols similar to CDMA, once all the commercial services have moved to the microwave bands.

They know how to do it. They have CORES already. You register, you get an ID, you use it to fill out forms and pay bills. In the case of whitespace, you register, you get an ID, you use it to fill out forms, and not pay bills. Easy.

FRS radios operate in the 400MHz range, which is UHF just like you desire. So there you go. :)
