The 900 MHz Telemetry module and base station provides up to 1 Watt of transmitter power, with a line-of-sight range of 40 miles or more depending on the antenna gain. Telemetry data rate can be set to 9,600 baud (about 1,000 characters per second) for the greatest range or 115,200 baud (over 10,000 characters per second) for about half the range.
When operating at full power and at high data rates (duty cycle) the internal temperature of the modem can increase by 40°C or more. When added to the already high temperature of a rocket waiting at the launch pad in the desert, the 85°C rating of the module can be exceeded. A heat plate that connects to the module heat transfer system reduces the temperature rise to 5°C.
Ground station modems are supplied and various optional high gain antenna systems (Omni-Directional, dipole and parabolic) are available. In addition, power output can be increased with licensed external amplifiers (5, 10 and 25 Watt models) with program control of amplifier power and bypass switch.

| Name: | UFC-3C-TEL 900MHz. Narrow Band Telemetry Module |
| Description: | The 900 MHz Narrow-Band Telemetry module and base station provides up to 1 Watt of transmitter power, with a line-of-sight range of 40 miles or more depending on the antenna gain. Telemetry data rate can be set to 9,600 baud (about 1,000 characters per second) for the greatest range or 115,200 baud (over 10,000 characters per second) for about half the range. All setup, configuration, calibration, status reporting and command functions can be performed via Telemetry. During flight data can be selectively sent on the downlink and commands for flight control sent on the uplink. |
