Narrowbanding Question

[jaolson101]

With jurisdictions now narrowbanding, in particular VHF frequencies, what alterations are required for a scanner to continue to hear them clearly? I'm using a Pro-96 and can't locate anything that particularly indicates wide or narrowband configuration.

Thanks,

At the simplest, nothing should change except a slight loss in audio volume at the speaker, and a slight loss of basic receive sensitivity.

Check out some of the old RPD UHF channels that have been repurposed to other depts & uses; many are already narrowbanded.

Yep. KB4MDZ has it correct. The Pro96/2096 does not have a "NFM" setting like more recent radios but it really should not affect you too much Jon.

Both guy's are correct.

I have Gaston County Fire programmed in my Spectra in my truck.

Gaston County has recently converted to Narrowbanding and I have seen a lot of there old MT-1000's & HT-1000's and mobiles showing up at last years Shelby Hamfest.

I just about have to turn the radio up to full volume to hear them. Then another agency statrs talking it will blow your ears off.

Just my thoughts

Another possible problem might be that you couldn't tune new in between channels like 155.0175. I'm not sure about your particular scanner but you might could get the ones that fall on a 12.5 KHz step like 155.9625 otherwise 2.5 KHz on one side or another of the frequency would be as close as you could get.
