Just exploring the 400 mhz band and heard/saw this P25 (NAC:201) transmission....coming through with errors. See photo. I searched online and all I could find was a cryptic description: "BP FPS USSS Uniformed Division (DC)" Maybe someone out there is familiar with this one? Signal strong here in Rhode Island. Monitored with SDR# & DSD Plus with RTL dongle and discone antenna. As I was typing this, just got a new transmission bit with different NAC's in there. No errors.....see pic (new) below. Also another brief transmission came through....VOICE, NXDN....see below.
