VHF MURS data radio modem

VHF MURS Channel Data Radio Modem

RV-M3-M datasheet(pdf)

Unlicensed Narrow Band
Featuring the range and power of a licensed narrow-band radio, with the convenience and size of a unlicensed spread-spectrum radio, the RV-M3-M is a narrow-band VHF data radio modem operating on the unlicensed MURS radio channels.

Very Long Range
No other unlicensed radio can match the range of the RV-M3-M.  With a link-margin of over 147dB, it will work well over 5 miles line-of-sight using simple omni-directional antennas.

Data, telemetry, or Remote Control
This MURS Data Radio modem is a 1/2 watt VHF data modem in module form, designed to easily integrate into OEM products.  Perfect to remote control, wireless data, and telemetry applications, it contains a high-performance transceiver with an integrated modem.  With over-the air baud-rates of 800 - 4800 baud, the RV-M3-M has incredible receive sensitivity, and outstanding communication range. 

Easy to Use
Configured with standard AT commands, the modem looks "transparent" to most applications.  Passing data between two RV-M3-M radio modems is as simples as sending a byte into or out of a serial port.  AT commands may be used to optimize the modem's performance for range, speed, system timing, power consumption, or simply to select a channel. Raveon will provide technical assistance with integrating this radio into your product, and obtaining FCC certification of the end-product.

Pricing  OEM prices start at $130 (100s). Contact Raveon for quantity prices.
