Also note that the frequencies that frankcastle posted above apply to both direct and repeater mode for the NPSPAC channels. When they go direct on NPSPAC, it is on the repeater output channel, so by monitoring the repeater output channel, you'll hear it all.
I mentioned in another thread that I now scan both non-rebanded and rebanded NPSPAC channels due to rebanding being a work-in-progress, and many radios already have the rebanded channels programmed. I've actually heard some traffic on rebanded ITAC4, although it was direct (simplex) and not through a repeater. So, it may pay off to monitor the rebanded channels as well. Just subtract 15MHz from the channels above to get the rebanded versions of those channels. So, where the non-rebanded ICALL is 866.0125, the rebanded version of ICALL is 851.0125. Do the same math for the rest of them and you're set. They also all use a PL tone of 156.7 Hz.
Also, don't forget the SAFE-T statewide analog conventional talkaround channel that is seperate from the NPSPAC conventional channels. It is actually listed in the IPSC's conventional interoperability literature. It is 855.2375 with a PL of 192.8 Hz. I've heard local law enforcement and fire/EMS using the channel while working high school football games, and it seems to work out well for that purpose. I would imagine its used similarly elsewhere in the state.
