Batboard

Will all HT750's on VHF do 2.5k Narrowband?

For ex. I am looking at model # AAH25KDC9AA3AN.

Any help is appreciated!

Not only is it programmable for 2.5 Khz peak deviation/12.5 Khz occupied bandwidth, it's synthesizer is also programmable for splinter channels. So the one word answer to your question is: yes.
