The State of Idaho has announced changes required for the VHF EMS frequencies.  These are the frequencies commonly identified as EMS 1, EMS 2, HEAR 1, HEAR 2, Statecom, Hospital, Ambulance, etc.

The changes will occur during the week of September 10, 2012.  Anyone using these frequencies must also make the appropriate changes during that same week. 

This will affect all EMS agencies, hospitals and any other agencies who have these frequencies programmed in their radios.  Anyone using these frequencies who does not make the required changes risks being unable to communicate with hospitals, ambulances, Statecom and others on these frequencies.  Failure to make these changes could also result in interference to others.

These frequencies are key components of interoperability plans nationwide.  When the announced changes are complete, the use of these frequencies by EMS in Idaho will be in compliance with those plans as well as the FCC narrowband mandate.

Questions regarding these changes should be directed to Mr. Robert Hugi, Idaho Statewide Interoperability Coordinator (SWIC), Public Safety Communications at 208-288-4007.

What follows is the relevant information necessary for technical personnel to implement the required changes:

    The frequencies being changed are:
    EMS Frequency 1 (A.K.A. VMED28):  155.340 MHz simplex
    EMS Frequency 2:  155.280 MHz simplex

    You must:

  1. Ensure that your radios are programmed for narrowband (12.5 KHz or 11K2F3E) operation on these frequencies.
  2. Program your radio to transmit sub-audible tone of 156.7 Hz on these frequencies.  This is also known as PL, CG or CTCSS.
  3. Program these frequencies for carrier squelch receive (CSQ).  Do NOT program the radio for PL, CG or CTCSS on receive on these frequencies.
