  1. Wisconsin Mutual Aid Communications Frequencies Annex K Update March 2011

  2. Introduction • The Mutual Aid Frequency Coordination Group (MFCG) has been established as a committee of the State Interoperability Council to manage the statewide mutual aid/interoperability channel resources. See the Wisconsin Interoperability Initiative website at www.interop.wi.gov for more information on the MFCG and all aspects of public safety communications interoperability in Wisconsin.

  3. Annex K • Wisconsin Mutual Aid Frequencies document • State plan for mutual aid communications. • Outlines public safety mutual aid and on scene tactical radio communications frequencies available in Wisconsin. • All public safety and governmental agencies should implement these frequencies.

  4. As interoperability planning in Wisconsin evolves and matures, a number of changes have been implemented since the last edition of this plan. Updates in this edition

  5. VTAC36 • VTAC36 has been established as a portable tactical repeater channel. It combines VTAC11 as output and VTAC14 as input. • A P25 digital version of this channel, VTAC36DG is also available. • Law enforcement special operations, such as SWAT, may use encrypted communications on the VTAC##DG channels. • These are Wisconsin-only channels. They are not part of the national plan.

  6. Nomenclature • National channel nomenclature has been established by the National Public Safety Telecommunications Council for nationwide interoperability channels. Those names are included for cross reference purposes.

  7. Nomenclature • Several channel names have been changed in order to integrate with the national naming standards. • WISPERN is now VLAW31 • VCALL is now VCALL 10 • VTAC1 – VTAC4 are now VTAC11 – VTAC14

  8. National Zone • A sixteen channel “National Zone” has been established to include the primary nationwide VHF interoperability channels. • Whenever possible, mobile and portable radios should include these channels for interoperability use when leaving Wisconsin or working with agencies in other states.

  9. Tone Squelch • Tone squelch on receive can now be optionally implemented on channels that were previously carrier squelch receive (such as some Fireground channels). • The NAC on the digital VTAC channels (VTAC##DG) has been changed from 800 to 293 to comply with the national standard.

  10. Narrowbanding • The State Interoperability Council has established policy for narrowbanding of all statewide mutual aid/interoperability channels during the April 2011 to November 2011 timeframe. • All VHF and UHF channels in the new Annex K document are narrowband.

  11. Narrowbanding • The changes listed in the document are to be implemented through the narrowbanding programming process. • Agencies should consider converting their communications system to narrowband operation in the 2011 mutual aid window, prior to the December 31, 2012 FCC deadline.

  12. Other Bands • The list of 700 MHz interoperability and low power frequencies are now included.

  13. MARC Repeaters • Occasionally a MARC repeater is left on after when it is no longer in use. This can cause interference to other agencies who need to use their MARC repeaters. • Agencies should be proactive in contacting the agency responsible for the operational MARC repeater and requesting that the MARC repeater be turned off.

  14. Questions • Chief Tom Czaja, Fox Point Police Department tczaja@vil.fox-point.wi.us • Carl Guse, State Frequency Coordinator carl.guse@dot.wi.gov
