The RMM and RDM radios should not be confused with the Motorola RDV. Channels 1-3 use "narrowband" Frequency Modulation (2.5 kHz deviation). 0000015621 00000 n
The frequencies below are commonly called "dot" frequencies as 5 watt or less portables are sold with these frequencies named for the color of the dot on the radio. But since GMRS is more common, there might be more people using the frequencies and a higher chance of hearing information through the channel. If businesses say that UHF is too congested for licensed UHF frequency and that's why they use MURS on VHF perhaps the crap below is one reason. They can provide business band ICOM VHF portables reprogrammed for the 5 MURS channels for a little over $100 each. There are two channels that are 154.nn mhz.

If businesses say that UHF is too congested for licensed UHF frequency and that's why they use MURS on VHF perhaps the crap below is one reason. This is against the FCC regulations but is widespread in certain areas due to the availability of open-band VHF/UHF radios, easily modified ham radio equipment that can transmit on the MURS frequencies and the adoption of the MURS frequencies by militia and prepper groups. Five frequencies across 16 channels, why? gewecke Completely Banned for the Greater Good. power on the IoT device. Due to the favorable propagation characteristics of the 150 MHz VHF band, telemetry systems using MURS are sometimes used as an alternative to unlicensed 26 MHz/27 MHz telemetry systems.
