Gary, 5 kHz deviation with a 3 kHz audio cutoff creates a signal at least 13 kHz wide, counting only the first set of sidebands. That's why many states went from 15 kHz to a 20 kHz channel bandplan on 2m a few years ago. There's nothing inconsistent in the FCC imposing both limits. 73, Paul, AE4KR

I did not write narrowband. After more study I see some possible contridictions in the rules as currently written for example, F3E/G3E GMRS emissions (probably the most common) are limited to 20Khz bandwidth but at the same time those emission types are also limited to +/-5Khz peak dev. I suspect the FCC doesn't really give a damn these days especially with rebanding, auctions, and now a congressional investigation on their doorstep.
