- 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.

accepted under United States Federal Communications
Commission Part 74.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the condition that this device
does not cause harmful interference.
Licensing of Telex equipment is the users
responsibility and licensability depends upon the
