What NAC codes are you looking for? The database is a great place to start, as @fxdscon has suggested, but if the system/radio isn't in the database you'd have to monitor the system just as if you were searching for PL codes.
Click on any RRDB P25 Systems Site Name and if a NAC has been user submitted it will be displayed on the Site Details Page.
The NAC you reference, 345, is the one used by the Tuscarawas County site for the statewide MARC-IP trunked system.I have a whistler scanner and i'm trying to figure out how to separate our departments. We only want to listen to fire and rescue.
Were in Tuscarawas County, Ohio. I'm using NAC tone 345. I have been reading and a lot of countys have more than 1 tone to
separate fire from police.
Can you help
I have the WS1065 that we got when they started talking about the new system.The NAC you reference, 345, is the one used by the Tuscarawas County site for the statewide MARC-IP trunked system.

None of the Whistler scanners support entering the site NAC for a trunked system. Only the Uniden SDS100 & SDS200 can use that detail, but that's really to prevent transmissions, on the same frequency, from a different site or system. If you are entering the site frequencies as conventional, with the NAC of 345, you are only hearing scattered pieces of conversations being carried on the site.
You did not specify which scanner model you are using, only that it is a Whistler radio. Presuming it is a digital capable scanner, you need to program this site as part of a trunked system, then you can enter only the talkgroups you want to monitor, whether that's only fire & rescue, or something else.
Note that there are two other sites on MARCS-IP, located in your county as well as the Tuscarawas County site.
