I downloaded my local Police Fire & Ems to my new handheld using freescan directly drawn from Radio Reference csv file. I am a police officer and have a radio that I am able to use to test to see if its all up and working. Sometimes it seemed to work fine, and other times it doesn't pick up anything. My display shows "NFM" usually when its not working. I cant figure out what this is. I am setting this scanner up for a friend who wants to listen as our county recently switched to this digital system. I cant figure out why this doesn't always pick up the system. I think I am doing something wrong. Just don't know where to start to trouble shoot. My departments portable radio has full signal. Sometimes, when I transmit on a talkgroup to see if the scanner picks it up, I see the alpha tag que up for a nano second in the display of the scanner but it doesn't hold...even though I am pushing the tx button for an extended time. Any help would be appreciated. If it helps, I am downloading New York State, Ontario county, p25 system police fire and ems for Ontario North and South.
