KTNN operates and is managed as a commercial AM radio broadcast station operating continuously over a clear-channel radio signal at 50.000 watts on 660 KHz.  Daytime broadcast covers much of the Four Corners area including the entire Navajo Nation, which compares in size to the state of West Virginia.

  The nighttime broadcast signal covers the western region of the United States (see coverage map).  The strength of this AM signal is further demonstrated by confirmed receptions from Canada, Mexico, New Zealand and Japan.  The strength of KTNN's signal is a credit to those who worked so diligently to obtain a 50,000 watt license.

  In earlier times, 50,000 watt stations were issued to provide a means to reach those who lived in rural areas.  Since most of America was rural, this concept was excellent and certainly served its purpose well.  But times have changed prompting the FCC (Federal Communications Commission) to halt issuing permits for super transmitters.  KTNN received the last 50,000 watt permit to be issued in the entire country.

  Many households in KTNN's listening area do not have access to cable television and those that do, receive "local" network stations originating from Albuquerque and Farmington, New Mexico, leaving a large void for information directly related to those living on and around the Navajo Nation
