Two Way Radio FAQ
Q: What is Narrow Band? When is Narrow Banding deadline?
Q: What are the penalties if my radio is not narrow band?
Q: Will my wide band radio work on the narrow band network?
A: On January 1, 2013, all public safety and business industrial land mobile radio systems operating in the 150-174 and 421-470 MHz radio bands must cease operating using 25 kHz efficiency technology, and begin operating using at least 12.5 kHz efficiency technology. This deadline is the result of an FCC effort that began almost two decades ago to ensure more efficient use of the spectrum and greater spectrum access for public safety and non-public safety users. Migration to 12.5 kHz efficiency technology (once referred to as Refarming, but now referred to as Narrow banding) will allow the creation of additional channel capacity within the same radio spectrum, and support more users. On April 26, 2012 WTB and PSHSB waived the narrow banding deadline for T-Band (470-512 MHz) licensees. As of January 1, 2011, the Commission no longer accepts applications for new wide band 25 kHz operations, or modification of existing wideband 25 kHz stations that expand the authorized interference contour.
After January 1, 2013, licensees not operating at 12.5 kHz efficiency will be in violation of the Commission's rules and could be subject to FCC enforcement action, which may include admonishment, monetary fines, or loss of license.
Equipment manufacturers should be aware that, as of January 1, 2011, the Commission no longer accepts applications to certify 150-174 MHz or 421-512 MHz band equipment capable of operating with only one voice path per 25 kHz of spectrum. Providers may manufacture and import previously-certified equipment with a 25 kHz mode until January 1, 2013.

Q: What is interoperability?
Q: Am I able to talk with other Agencies?
A: Interoperability is the ability of different governmental agencies to communicate across jurisdictions and with each other.
The National Emergency Communications Plan (NECP) focuses on the emergency communications needs of response personnel in every discipline, at every level of government, and for the private sector and non-governmental organizations (NGO). Emergency communications is defined as the ability of emergency responders to exchange information via data, voice, and video as authorized, to complete their missions. Emergency response agencies at all levels of government must have interoperable and seamless communications to manage emergency response, establish command and control, maintain situational awareness, and function under a common operating picture, for a broad scale of incidents.
Emergency communications consists of three primary elements:
1. Operability—the ability of emergency responders to establish and sustain communications in support of mission operations.
2. Interoperability—the ability of emergency responders to communicate among jurisdictions, disciplines, and levels of government, using a variety of frequency bands, as needed and as authorized. System operability is required for system interoperability.
3. Continuity of Communications—the ability of emergency response agencies to maintain communications in the event of damage to or destruction of the primary infrastructure.
Q: What is 10 codes or use of plan language?
A: Ten-codes, also known as ten signals, are code words used to represent common phrases in voice communication, particularly by law enforcement and in Citizens' Band (CB) radio transmissions.
The codes, developed in 1937 and expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO), allow for brevity and standardization of message traffic. They have historically been widely used by law enforcement officers in North America but due to the lack of standardization, in 2006 the U.S. federal government recommended they be discontinued in favor of everyday language.
Q: Who gets a two-way radio?
A: Any Navajo Nation Department that has a need for two way radio communications. Must provide a valid memorandum requesting for two way radio services.
Q: Who replaces two-way radio accessories?
A: The Navajo Nation; if the radio belongs to the Nation
Q: What is a radio tower?
A: Radio masts and towers are, typically, tall structures designed to support antennas (also known as aerials) for telecommunications and broadcasting, including television. They are among the tallest man-made structures. Similar structures include electricity pylons and towers for wind turbines.
Q: Where are the towers located?
A: Piney Hill, Dezza Bluff, Roof Butte, Yale Point Black Mesa, Navajo Mountain, Preston Mesa, Nah Ah Tee, Hunters Point, Roberts Ranch, Ganado, Toyei, Little Black Spot, Mount Powell, LaMosca, Torreon, Huerfano Mesa
Q: Where can I find your work order form?
Q: Can I email a work order request?
A: Yes, to Barbara Yazzie at firstname.lastname@example.org
Q: How long does it take for an installation?
A: 8 hours
Q: How long does it take to reprogram a radio?
A: 4 hours
