I should clarify that I was referring to new commercial gear coming stock with
4Khz dev on 20Khz channels as one of the selectable bandwidths per channel. So
far as I know most new VHF/UHF amateur gear these days is user selectable as
either wideband or narrowband. I'm working more today with the newer Moto stuff
(Astro, Pro, and Mototrbo) and don't keep up on the amateur gear as much I used
to.
