Oklahoma Field Operations Guide

Latest News: Printed copies of the OKFOG Version 2.0 are now available! You can also access an electronic copy at the bottom of this screen.

  OKFOG Version 2 Cover

Major updates to Version 2.0 include:

  • The addition of a statewide radio programming template, which was developed by members of the SIGB to be used as the recommended standard for all public safety radios in the state.
  • The removal of several pages containing outdated information.
  • The addition of a Record of Change page, which will be updated each time a revision is made.
  • A new cover page to better distinguish Version 2.0 from the original publication.


The OKFOG is a pocket-sized communications quick-reference booklet designed to:

  • Assist all public safety personnel in the use of interoperable radio resources on a day-to-day basis, as well as during large-scale events which necessitate a multi-disciplinary and multi-jurisdictional response. 
  • Provide guidelines and Standard Operating Procedures (SOPs) for the proper use, naming, and programming of interoperable radio channels.
  • Be utilized by both emergency responders and radio technicians to ensure that every public safety agency in the state of Oklahoma is equipped with optimal interoperable capabilities.

The OKFOG is also compliant with the National Incident Management System (NIMS)

The information in this guide is intended to assist public safety personnel in identifying the proper radio channels to use when responding outside their primary service area, whether in another part of the state or to a major disaster in a different state. We encourage you to have as many of these interoperability channels programmed in your radio as possible.

Development and Update Process

Version 1.0 of the OKFOG was developed throughout 2010 and was published in the first quarter of 2011. 

Development of Version 2.0 began in August, 2013. Published copies are expected to be made available in the first quarter of 2014. 

Periodic updates will be made to the electronic version of the document and will be highlighted on the newly established Record of Change page. Major revisions are scheduled to occur every two years. Should you identify any errors in the OKFOG, please email 

Presentation and Training

The OKFOG: An Introduction for First Responders

Radio Programming

Agencies are encouraged to program as many interoperability channels into their radios as possible.

Please note: There has been some confusion regarding the differences in programming for the Oklahoma VHF Interoperability Channels and the National VHF Interoperability Channels. 

The Oklahoma VHF Interoperability Channels (listed on Page 100 of the OKFOG) must use a 12.5 kHz bandwidth by January 1, 2013. If capacity permits, it is recommended that these Oklahoma VHF Interoperability Channels be programmed as both wideband and narrowband in radios. If capacity is limited, the Oklahoma VHF Interoperability Channels should be programmed as wideband and reprogrammed for narrowband emission as part of a communications plan to transition local frequencies to narrowband.

In contrast, the National VHF Interoperability Channels must be programmed for narrowband operation only. Do not program them for wideband operation, as this may cause unwanted interference. 

Version 2.0 of the OKFOG contains a statewide radio programming template designed to assist both emergency responders and radio technicians in programming the maximum number of interoperability channels in their radios as possible. 

For clarification and guidelines on the intended use of the various frequencies listed on the programming template, please click on the link below.
