Don't think this has been posted before - the US FCC announced that radiomics using the 700 MHz band (old TV white space) will have to stop by 12 June. There are more details at

Operation of Wireless Mics in 700 MHz Band (http://www.fcc.gov/cgb/wirelessmicrophones/)

I believe that's a typo. The FCC 700mhz ruling went into effect in June 2009.

The FCC has previously prohibited the sales of new wireless mics in the 700mHz band late in 2008 and had announced an operation ban of existing mics would be forthcoming. The new news is that the ops ban is definite and the announcement of the effective date as this coming June. Previous prevailing belief was that if you already had a 700mHz kit you could probably get away with using it for a number oi years yet, now it looks like they're going to get hard-a**ed about it sooner than folks expected.
