We will soon be offering the RF320-series narrowband radios that will replace and provide over-the-air compatibility with our RF310-series radios. The new series is based on Ritron's rugged line of DTX-L narrowband analog radios. Each radio will include a configured Ritron DTX-L radio, mounting bracket, and cable for connecting the radio to a radio modem. Models that support VHF and UHF frequencies will be available. Narrowband radios provide stable long-range communication.
