- Telex Model TR-80N Beltpack
- Each BTR-80N base station can be used with one to four TR-80N beltpacks. The TR-80N transmits within the 614 to 722 MHz range (TV Channels 38-55). It receives in the 482 to 608 MHz range (TV Channels 16-36). The TR-80N transmitter operates on a single frequency within an 18 MHz wide section of the transmit frequency range. The receiver also operates on a single frequency within an 18 MHz wide section of the receiver frequency range.
- The transmitter has three selectable conducted output power output levels; 5mW, 50mW and 100 mW. The transmit power can also be set to automatically reduced to the above listed power levels when the unit is close-in to the base station to aid in intermodulation reduction and unnecessary transmit power.
- Operating frequencies can be selected from pre-set groups or the user can select special operating frequencies within the 18 MHz wide allotments.
- Transmit and receive antennas are attached to the TR-80N. Either or both unscrew for field replacement but are not coaxial connectors.
