In many larger populated areas UHF frequencies are allocated for Public Safety in the UHF TV spectral band from 470−512MHz. These are primarily used by police and fire LMR (Land Mobile Radio). It is illegal to operate in this spectrum band with licensed or unlicensed microphones.
Channels 14,15, & 16 are allocated by the FCC in New York City for Public Safety LMR.
Aside for from the fact that it is illegal to operate non licensed devices in this spectrum. There is also a high probability that LMR radios operated in this spectrum band will interfere with wireless microphones. LMR radios in this spectrum transmit at 5 watts and key in intermittently when the talk button is pressed on the radio.
Auto Scan on the face of wireless receivers will not avoid this Spectrum band. Custom user frequency groups can be used to provide frequency groups that avoid this spectrum.
Below is a table of Public Safety designated spectrum band organized by metro area.
CFR data is current as ofJuly 21, 2020
Approximately the first 3 Mhz of each public safety channel are allocated to fixed transmitters. The second 3 Mhz are assigned to mobile radios. Although it looks like there might be spectrum available it is illegal to operate in this spectral band. During a large event it is highly probable that public safety radios will be in the venue and nearby. Interference with these frequencies is not only illegal it can risk the health and safety of the public.
