Texas A and M Forest Service (TX)

From The RadioReference Wiki

The Texas A&M Forest Service was created in 1915, as a service within Texas A&M University, that will "assume direction of all forest interests and all matters pertaining to forestry within the jurisdiction of the state." Prior to 2012 the agency's name was Texas Forest Service.

TFRs requested for aerial firefighting usually have a contact frequency listed. This is usually the Air-to-Air zone primary or secondary frequency but sometimes new incident-specific frequencies are used which are not listed in the database. See the FAA Temporary Flight Restrictions page.

VHF FM Federal Frequencies

During large fires when resources from other states and federal agencies are brought in, National Incident Radio Support Cache Command, Tactical and Air Tactics channels may be used.

NIRSC Tactical and Government Common channels are often used by the federal wildland fire agencies as travel and talk channels.

Agency specific (USFS, FWS, NPS, etc.) frequencies may also be used as well as temporary incident specific frequencies ordered from the NIFC.

Air Tactics

From unofficial 2020 NIFC National Air-to-Ground Frequency List. May not be current or accurate.

The frequencies from old air-to-air zone maps and other sources are listed below. They may or may not be used again in the future.

At times when there are multiple aircraft working a large fire or multiple fires in the same area, alternate frequencies may be ordered from the National Interagency Fire Center (NIFC) to separate fixed-wing and rotor-wing traffic or to prevent interference to operations in other areas.

Some of the frequencies listed below were probably temporary incident specific frequencies and may or may not be used again in the future.
