Most tracking radios operate at 1200 or 2400 baud over the air. The M7 series operate at 4-10X that speed using CPFSK2/4 modulation for data rates as high as 19.2K over the air.

TDMA (Tim-Division Multiplexing) is built in every M7 GX radio modem. With TDMA, 100 vehicles may be tracked with 10-second updates, and no RF interference. Even when using a repeater!

All location transmissions are compressed, allowing not only location to be sent, but also voltage, temperature, input status, speed, direction, and time-and do this with less air-time than most radios use to simply transmit their location.

The M7 transceiver has a fast-lock PLL with lock-time of only 1mS, and a T-R turn-around time of less than 3mS. This enables the radio to make real-time transmissions in TDMA or conventional modes.

The M7 GX will periodically transmit its location, along with voltage, temperature, input status, speed, direction, and UTC time. It powers-down the radio and GPS when not in use, reducing its average current draw to less than 30mA.

The M7 GX will periodically transmit its location, along with voltage, temperature, input status, speed, direction, and UTC time. It will also receive the location of other M7 GX radios in its radio range for display on a GPS plotter or hand-held GPS connected to the M7 GX's NMEA RS-232 interface.

The RV-M7 will periodically transmit its location. It will also output the location of other RV-M7 radios in its radio range for display on the RavTrack PC software program.

If you already have gps plotter, you may connect it to RV-M7 with the-LX option. This gives the unit all the features of the-GX version with the GPS, but uses your GPS NMEA data feed as the source for its GPS signal. It will output the lication of other M7 GX radios in it radio range for display on a GPS plotter or hand-held GPS connected to the RV-M7's NMEA RS-232 interface.

Any M7 GX may also be a store-and-forward repeater. With a 3mS attack time, the repeated signal has only milliseconds of latency, and coverage can be 10s of miles.
