The BTR-30N gives users the ability to increase their wireless system capacity
For use in an already congested UHF spectrum, RTS has launched the BTR-30N UHF/VHF wireless intercom system with a hybrid, dual-band design. The two-channel, narrow-band system supports up to four TR-30N (dual-channel) or TR-32N (dual-channel stereo) frequency-agile beltpacks. Designed for high performance with minimum spectrum usage, the system is suited for broadcasting, education, event production, hotels, houses of worship and theatres.
By taking advantage of the lower VHF frequencies, the BTR-30N gives users the ability to increase their wireless system capacity beyond the more limited operating range of UHF alone. Two-way radio systems use one frequency for signals sent from the beltpack to the base station and another for signals sent from the base station to the beltpack. In most systems, these two frequencies belong to the same band and there is always some separation between them. With the BTR-30N, however, signals from the base station to the beltpack are sent in the VHF spectrum (174–216MHz) and signals from the beltpack to the base station use UHF (482–572MHz).
Providing 25kHz of modulated bandwidth, the BTR-30N allows more users per channel in the VHF spectrum, along with a reduced footprint in the UHF band. The system allows the beltpack operator to choose between two separate audio channels of communication, with the base station tracking the beltpack selection. This allows the user the flexibility to create a party line and a private line within the same beltpack. The units perform at line-of-sight distances of 90m and the effective operating range can be extended further using an RTS antenna system.
The BTR-30N provides all the standard features of the BTR-80N UHF system, such as DSP and Intelligent Power Control. Additional features include multiple selectable transmitter power outputs, selectable receiver squelch control, RF metering on base station and beltpack displays, remote battery indicators on the base station display, beltpack battery percentage display, low battery tone indicator on the beltpack, AC or DC power input on the base station, simultaneous two-wire and four-wire operation, and the ability to expand a system for a very large number of users in half-duplex mode with the First-On-Latch-Out feature.
