Stumbled on this the other day and thought it was interesting. Since MURS is unrestricted, might it be ok to transmit encrypted data that would otherwise be prohibited on Ham bands? Looks like it just needs power, an antenna and a pc connected via serial port. VHF radio modem 1-2 watts 4800/9600bps MURS band radio modem VHF Data Radios | VHF Data Radio | VHF Radio Modem Haven't dug too deep but they look to be $570@ here: RV-M7-VM Raveon's RV-M7-VM data radio modem is a high-speed FCC Part 95 certified data radio designed for telemetry, SCADA, AVL, wireless data, mobile-data and remote control applications. The RV-M7-VM data radio transceiver is designed exclusively for use on the license-free MURS radio channels. The FCC has set aside 5 VHF radio channels, limited to 2 watts of transmit RF power, for license free use in the United States. More information about thise "MURS" radio channels is available in our application note AN115. The 5 MURS channels are: 1 151.820 MHz 2 151.880 MHz 3 151.940 MHz 4 154.570 MHz 5 154.600 MHz It is one of the most versatile and fasted data radio modems. Included in each unit, are advanced networking, error correction, and diagnostics. Featuring an all digital base-band, this one radio modem works on wide and narrow band channels at baud rate from 800 to 19200. It may be ordered with an optional IP65 weatherproof enclosure. An Optional internal GPS ( -GX option) allows the M7 to send its positionand status at pre-set intervals using TDMA channel access, allowing hudreds of vehicles, assets, or personnel to be GPS tracked. A GPS AVL system built with M7 transceivers, can track as fast as 200 vehciles with 10-second updates or 20 vehicles with 1 second updates. The M7 series data radio is the fastest and most efficient VHF AVL radio on the market. See all of Raveon's AVL technology and software at www.ravtrack.com. The M7 leads the industry in many areas including technology, features, and price. It has some of the fastest over-the-air data rates, TX-RX switching times, and power-on times. It is one of the smallest data radios in its class. It is one of the most rugged data radios made. It is one of the lowest power-consumption radios available. It has programmable over-the-air data rates and IF bandwidths. And its price will pleasantly surprise you.
