3. Locomotive Transmitter Operation
It is the responsibility of the licensee to operate this radio transmitter in compliance
with the terms of the license and FCC or Industry Canada service rules for 220-222
MHz, i.e., FCC Rules Part 90T and Industry Canada SRSP-512, or in the U.S. only,
operation on 217.6-218 and 219-220 MHz frequencies is subject to FCC Rules Part
80.
3.1 Locomotive radio channelization and frequency range
The Locomotive radio can be licensed and configured to transmit on any one of 80
selectable 25-kHz spaced channels ranging from 220.0125 to 221.9875 MHz inclusive
in the 220-222 MHz Radio Service defined by Part 90 Subpart T. The spectrum
included corresponds to all 5-kHz wide FCC channels numbered from 1 at 220.0025
MHz to 400 at 221.9975 MHz. Each Locomotive radio transmission occupies five of
the FCC-defined 5-kHz channels. The lowest Locomotive radio channel center
frequency is in the center of FCC channel 3 and the next is FCC channel 8, then 13,
18, and so on, up to the highest in the center of channel 398.
In the USA only, the radio can be licensed and configured to operate on 56
additional (Part 80) frequencies in the ranges 217.6125 to 217.9875 MHz and
219.0125 to 219.9875 MHz.
3.2 Locomotive channel restrictions
Section 90.715 of the FCC Rules lists the authorized frequencies of the 400 total 5-
kHz-wide channels. According to §90.733(d), these can be aggregated into larger
channel widths with the exception of FCC channels 161-170 and 181-185. Therefore,
the Locomotive radio may not transmit on those channels or their 221 MHz
counterparts, 361-370 and 381-385. This corresponds to Locomotive radio
frequencies 220.8125, 220.8375, 220.9125, 221.8125, 221.8375, and 221.9125 MHz.
