Is noaa weather wide or narrowband?

Nothing to do with deviation? Is that why narrowband uses 2.5 kHz deviation and wideband uses 5.0 kHz deviation?

If you had a 25 kHz channel at 10 kHz deviation, your maximum modulation frequency would be 2.5 kHz.

Regardless, NOAA is still wideband FM (5 kHz deviation / 16.0 kHz bandwidth).

They are unlikely to change soon due to the sheer number of receivers in use that do not support narrowband specs.

They are unlikely to change soon due to the sheer number of receivers in use that do not support narrowband specs.

As well as all the Marine VHF radios that are wide band

I think this has run its course.
