I have been receiving reports of some recent changes in the Federal Protective Service (FPS) radio channels in multiple cities.
First, listeners were not hearing the normal FPS traffic on 410.8000, 410.7000, or 410.9000 MHz in the eastern Georgia region. After some additional monitoring, it was determined that they had changed their P-25 Network Access Code (NAC) from N270 to N201.
I also received word that a new FPS repeater on 410.8000 MHz, N201 was being used in the Chicago area. This seems to replace the long used FPS channel of 406.7000 MHz, N201.
Nashville, TN has also reported a new FPS presence on 410.8000 MHz, N201 as well, so maybe they are attempting to coordinate everything into a regional or national channel plan.
This may indicate other changes are afoot, so keep an ear on the federal UHF channels for any new activity.
