National Public Safety Interoperability Channels
Refer to APCO/NPSTC ANS 1.104.1-2010 Standard Channel Nomenclature for the Public Safety Interoperability Channels and USDHS National Interoperability Field Operations Guide (NIFOG) for detailed information.
Many state governments publish communications interoperability plans on their web sites. See the links at the bottom of this page.
Some states and local areas have their own interoperability or mutual aid channels or trunked system talkgroups which are used instead of, or in addition to, the channels listed below. Some trunked systems may have talkgroups permanently or temporarily patched to one or more of the channels listed below.
State and regional frequencies are usually found on the Common/Shared or Statewide drop-down list on the main RadioReference Database page for each state, or on county database pages.
A D suffix indicates a repeater output frequency used in simplex mode (for example, LLAW1D is simplex on the output frequency of LLAW1).
Scanner users should program the frequencies below with no tone and the mode set to receive both analog and digital transmissions to reduce the possibility of missing communications.
VHF Low Band
- In analog mode all radios should transmit PL 156.7 and receive CSQ (carrier squelch) unless PL decode is necessary due to interference.

VHF High Band
- In analog mode all radios should transmit PL 156.7 and receive carrier squelch (CSQ or no tone) on VCALL10 - VLAW32 unless PL decode is necessary due to interference.
- In analog mode end user radios should transmit PL 136.5 and receive carrier squelch (CSQ or no tone) on VTAC33 - VTAC38. Repeaters should transmit CSQ and receive PL 136.5.
- In APCO P25 dgital mode all radios should transmit and receive NAC $293.
- VTAC17 and VTAC17D are VHF marine band channels and their use is limited to inland VHF Public Coast Station Areas (VPCSA) 10 through 42.
