Interoperability Zone for VHF Radios
The following DHS agencies use radios in the VHF frequency band:
  • Customs and Border Protection (CBP)
  • Federal Law Enforcement Training Center (FLETC)
  • Immigration and Customs Enforcement (ICE)
  • Office of the Inspector General (OIG)
  • Transportation Security Administration (TSA)
  • United States Coast Guard (USCG)
  • United States Secret Service (USSS)

If you have a VHF radio, you should know how to find the DHS common interoperability channels: DHSNET and DHSTAC

Once your radio is reprogrammed with the new DHS common template, the 16 interoperability channels in Zone IO1 will appear as shown in the table in the following screen.

If the radio has not yet been reprogrammed with the new DHS template, then the common channels may be in other existing zones within your radio.
