MURS datalink radio data data radio on 151.8800 MHz MURS channel 2 Multi Use Radio Service 151.88 MHz 11.25 kHz bandwidth limit on 151.820 MHz, 151.880 MHz, 151.940 MHz. 20.0 kHz bandwidth limit on 154.570 MHz and 154.600 MHz. FSK data and FM narrow band NFM NBFM phase modulation angle modulation FM voice are the most popular modes but any mode may be used as long as it meets the bandwidth requirements. This includes regular AM voice A3 A3E emission, J3E SSB single side band and misc. digital modes RTTY packet PSK31 FSK PSK frequency-shift keying OOK on-off keying CW Morse Code. Basically all voice traffic on MURS is FM mode. Digital voice is also allowed so NXDN P25 Project 25 DMR MotoTRBO TRBO 2-slot DMR IDAS NEXEDGE narrow band or wide band 4K00F1E 8K70F1E 8K10F1E 9K20F3E 9K10F3E 11K0F3D 11K0F1D 11K0F2D 11K0F1D 9K20F3D 9K20F1D frequency-shift FM data. Very popular dog tracker hunting dog radio collars GPS collar driveway alert alarm telemetry remote sensing networks, remote control supervision and nearly an infinite number of other possible uses. MURS has a power limit of 2 watts PEP but no limit on antenna gain. There are limits on antenna height but they are not restrictive.

For data link and telemetry purposes, MURS is an excellent choice. VHF line of sight. However, for rough situations with obstructions, the higher-power data link capabilities of systems like the Linear XT-1 XT-4 and similar 26.995 MHz 27.045 MHz 27.095 MHz 27.145 MHz 27.195 MHz - 4 watt power limit or the superior 27.255 MHz 25 watt power limit!!! is the best option. With a base station antenna, 10-20+ mile range is possible. Most systems use 4 watt, 7 watt or 10 watt FSK transmitters on 27.255 MHz but 12 watt systems do exist. 4 watt and 2 watt transmitters are found on the 26995/27045/27095/27145/27195 frequencies in addition to 27255. Bandwidth is limited to 8 kHz on the 26-28 MHz RC frequencies. Like MURS, the RCRS is covered under Part 95 of the FCC rules.
