Narrow banding

I'm just curious, are the ham / amatuer radio frequencies subject to the same FCC narrow banding requirements as the commercial bands? I haven't read the full law, since I only deal with commercial 2-way and reading though thousands of pages of government documents is not my idea of a good time.

Voice - narrow band
Angular modulation is used in narrow band voice applications in Amateur radio. Different configurations are used on HF, and VHF/UHF.

VHF/UHF application is usually FM with a 6dB/octave pre-emphasis over the whole voice band (in effect PM) with a peak deviation of 5kHz. Carson's rule estimates the bandwidth for a 3kHz voice band at 2*(3+5) or 16kHz. This is commonly employed in a 25kHz channel spacing plan.

The hams dont have to change.All others under the law will aircraft,trains are but a few that go narrow band July 1 2010. Sprman : )

Thanks for the replies, and thank you FCC for the extra job security. Lots of radio reprogramming and sales for us over the next 2.5 years, plus we're taking over the teritory of another shop that is closing down next week. Things are about to get busy!
