As have many other parts of the country - to 12.5 kHz on 440. But, when you say narrowbanding, are you talking the actual users switching from NBFM (16.0 kHz BW) to SNFM (11.0 kHz BW) or are you just talking about the bandplan going from 25.0 kHz channels to 20.0 kHz channels and everyone is still using NBFM as they have for the past nearly 40 years?
