Does anyone know the latest info about what is going to happen to the FM band
when the FCC forces all of the VHF television stations to give up their
broadcast band and switch to the new freqency allocations for digital TV?


Nothing.

As soon as the conversion to D-TV is complete, the TV stations which were
temporarily relocated to other channels, some to VHF, but most to UHF, can
return to their original channel, but on digital.
