The Narrowbanding of CPD

[werinshades]

Most Zones have been narrowbanded as of yesterday...Zone 5 was the latest. The following Zones have been narrowbanded as of today: Zones 1,2,3,4,5,10,11,12,13....

The following Zones are scheduled to be Narrowbanded: Zones 6,7,8,9....Districts will be turning in their radios to be narrowbanded, receive "temporary replacement" radios, then the assigned radios will be returned and be fully narrowband complianant.

Once all the Zones are Narrowbanded, the City-Wide channels will be next with the same radio procedure to be followed for assigned units on their specific city-wide.

For us scanner listeners, you'll know your Zone is being re-programmed for narrowbanding as they switch to City-Wide 4 at 0700 hrs.on that day (Has been Tuesday's lately). They usually switch back around noon and tell all cars to switch back to your normal Zone.."switch to A-xx on your radio". A-Bank is the Zone narrowband...the City-Wides will be B {1-7} when they become narrowband complianant.

No CPD digital...same Zones and City-Wides as now. They now have "canary yellow" XTS 5000's. A-Bank is narrowband...B-Bank is mix of narrowband (1-7) and wideband (10-16) City-Wide channels...C-Bank is wideband Zone channels. Zone 6 is narrowbanded as of last week...Zones: 7, 8,9 plus all the city-wides are left to narrowband as of today.

As of now are there anymore updates on narrowbanding? The Citywides sound like they may have gone too.

Really nothing new. No special programming needed, I've heard dispatchers tell the officers to use B-2 (Narrowband-City-Wide 2), or B-11 (Wideband-City-Wide 2) at diffrerent times and both seem to work. To my knowledge, the city-wides haven't been narrowbanded.
