(c) As used in this section, "police radio" means a radio that is capable of sending or receiving signals transmitted on frequencies assigned by the Federal Communications Commission for police emergency purposes
But, it is receiving the signal or is it receiving something else that is actually receiving and transmitting the signal? Your app isn't actually receiving the signal transmitted on the FCC frequency. It's receiving it via the cell tower via the app's broadcast.
But, we aren't lawyers, so it's probably just an academic discussion.
