700 MHz
In February of next year, analog teevee broadcasting goes away here in the States. If you don't have a modern digital set, use cable or satellite, and get your signal OTA , then you are out of luck. The FCC, or whoever, issues $40.00 vouchers for aerial-bound old-fashioned non-digital tv owners like myself to purchase set-top digital converter boxes. This doesn't cover the entire cost, but with most converters going for around $50.00, you don't have to cough up all that much.
So, that being said, why doesn't the FCC give a little financial support to the 700MHz users? Like the vouchers they provide for the unwashed masses and their ancient TV receivers. Give them a voucher, or buy their kit outright. Lord knows that they made enough money from their spectrum auctions.
