RTR-MXRTR-LSRTR-HPRTR-RMI
Every HydroLynx transmitter, repeater and receiver carries an FCC narrowband-compliant radio matched to your licensed frequency. The RTR-MX serves data transmitters, the RTR-LS serves receivers and repeaters, the RTR-RMI ScadaLynx radio provides bi-directional links — and when a path is long or obstructed, the RTR-HP steps transmit power up to 30 watts.
Which radio goes where?
| Radio | Role in the network | Bands | Channels | Datasheet |
|---|---|---|---|---|
| RTR-MX Narrowband Radio Link | The RF link inside Data Transmitters | VHF 148–174 MHz | 16 (RX/TX pairs) | |
| RTR-LS Narrowband Radio Link | The RF link inside Data Receivers & Repeaters | VHF 154–174 · UHF 400–420 MHz | 8 (RX/TX pairs) | |
| RTR-RMI ScadaLynx Radio | High-speed transparent modem for bi-directional, polling & control with 50388 systems | VHF 132–174 · UHF 403–512 MHz | 1, field-programmable | |
| RTR-HP High-Power Radio | 30 W transmit for long or obstructed paths on transmitters or repeaters | VHF 148–174 MHz | Field-programmable |
Specify your frequency at order time. Each channel carries a receive and transmit frequency pair; the pair can differ but must fall within the radio’s band. Packaged stations default to the RTR-MX Maxon 5 W radio with enclosure; the RTR-LS Ritron 5 W and RTR-HP Ritron 30 W are also available. Why we ask for your frequency →
