FCC Narrowbanding Mandate for ASTRO Radios |
(Learning
and Programming Radio Features) |
|
By
January 1, 2013: Per the Federal Communications Commission (FCC)
Rule Part 90 mandate on narrowbanding, in an effort to promote greater
spectrum efficiency, the FCC requires that all Public Safety and Industrial
/ Business licensees must transmit on a
12.5 kHz channel bandwidth
or better. The exception to this Part 90 narrowbanding mandate applies
only for radios operating within 470-512
MHz frequencies (T-Band), which will continue to support a 25 kHz channel
bandwidth, as well as specific exception frequencies
noted below. The FCC requires that a radio be certified to operate on
Part 90 VHF or UHF radio systems, and that the radio-user have an FCC
license to operate the radio on those frequencies.
All radio codeplugs that are subject to this mandate are identifiable by a "Q507/G507 - 12.5 kHz FCC Mandate" option in the codeplug's Purchased Feature Name list. |

After FLASHport Upgrading the radio to add the "Q507/G507 - 12.5 kHz FCC Mandate" option, you must revisit the transmit bandwidth of all assigned channels to ensure that they comply with the FCC Narrowbanding Mandate. |

Cloning to a target radio which has the "Q507/G507 - 12.5 kHz FCC Mandate" option from a source radio or codeplug that does not have this option holds certain restrictions. See the Cloning Warnings. |
