Channels 8-14 are simplex only and limited to 0.5 watt power output. GMRS users may transmit up to 5 watts on 462.5625 MHz, 462.5875 MHz, 462.6125 MHz, 462.6375 MHz, 462.6625 MHz, 462.6875 MHz and 462.7125 MHz (channels 1-7).
Licensed GMRS users and unlicensed FRS users are limited to 0.5 watts on 467.5625 MHz, 467.5875 MHz, 467.6125 MHz, 467.6375 MHz, 467.6625 MHz, 467.6875 MHz and 467.7125 MHz (channels 8-14).
Licensed GMRS users may transmit up to 50 watts on 462.550 MHz, 462.575 MHz, 462.600 MHz, 462.625 MHz, 462.650 MHz, 462.675 MHz, 462.700 MHz and 462.725 MHz (channels 15-22). GMRS users may use these frequencies for simplex (non-repeater) use or as repeater output frequencies. Because of the extensive simplex FRS use of all 22 channels, GMRS users are strongly encouraged to use CTCSS or DCS on any repeater pair and for simplex operations.
GMRS Bandwidth - Deviation "12.5 kHz" NFM and "25 kHz" FMGMRS license holders (licensed GMRS users) are permitted to use regular 5 kHz deviation FM (16K0F3E emission or 20K0F3E emission - referred to as "25 kHz wideband" or "25 kHz channel" in Motorola literature) on channels 1-7, channels 15-22 and the 8 repeater pairs (output frequencies are, of course, channels 15-22). 5 kHz deviation is often referred to as wideband mode, "WIDE" mode or "FM". Narrowband (12.5 kHz channel) 2.5 kHz deviation - 11K3F3E, 11K2F3E, 11K0F3E emission - "NARROW", "NARR" or "NFM" mode on most radios use is required on channels 8-14 under FCC regulations. Use of narrow mode on channels 1-7 when communicating with FRS units is recommended. Use of narrow mode on all 22 channels is recommended when communicating with FRS units in the simplex (non-repeated) mode.
When using a repeater, generally 5 kHz deviation (wide mode) is used. Check with the repeater owner/operator to see if their repeater is operating in 5 kHz deviation or 2.5 kHz narrowband deviation. There are some advantages to running a GMRS repeater in narrow mode (2.5 kHz deviation). This is especially true in urbanized areas and other locations where the GMRS repeater input frequency is subject to large amounts of adjacent channel interference from simplex activity on channels 8-14.
