New ARES Simplex Frequency Plan Approved!

NOTE!  Every ham should have these simplex frequencies programmed into their mobile and HT radios.  It is good to be prepared before the emergency.

Updated with the correct frequency for Washington and Fayette Counties

New ARES Simplex Frequency Plan Approved!

At the February 9th WPA Cabinet Meeting, the proposed WPA ARES Simplex Frequency Plan was unanimously approved. This new suggested frequency plan improves our use of scarce frequencies, and greatly enhances ARESMAT (mutual aid) operations, by ensuring that every radio has every frequency pre-programmed into it for the entire section!

Four simplex frequencies were chosen to meet the following criteria:

  • specified as Simplex Channels in the WPRC 2-meter Band Plan\
  • at least 30 kHz separation from each other
  • at least 30 kHz separation from any repeater input or output frequency (as specified in the WPRC Band Plan)
  • at least 30 kHz separation from the 146.52 MHz National Calling Frequency

Additionally, they were chosen to align on 30 kHz-spaced channels to facilitate their availability on older radios, including ancient crystal-controlled radios and 1970s-vintage synthesized rigs. The result provides maximum compatibility with 90% or more of all radios that might be pressed into service.

Here are the counties and recommended frequencies:

146.55 “TAC-5”
Allegheny, Clarion, Clearfield, Greene, Huntingdon, Mercer, Potter, Somerset, Warren

146.58 “TAC-8”
Beaver, Blair, Clinton, Franklin, Jefferson, McKean, Venango, Westmoreland

147.54 “TAC-4”
Armstrong, Cambria, Cameron, Erie, Fayette, Forest, Fulton, Lawrence, Mifflin

147.57 “TAC-7”
Bedford, Butler, Centre, Crawford, Elk, Indiana, Washington
