Armstrong Transmitter is showing its TRX-HD series of FM translators, which it says are designed to transition with a station as it transitions from analog-only broadcasting to the digital hybrid mode and eventually to broadcasting in full digital.
The TRX-HD receives an FM station’s entire signal payload over the air, including its HD Radio digital component. The signal content is transferred to the TRX-HD transmit site for retransmission on the translator frequency.
Features include front-panel frequency agility with LCD screens that independently display the parameters of the receiver and transmitter sections, while complete parameters are available via RS-232 and DB-25 connectors on the rear panel for remote control.
The TRX-HD is available at three power levels. The TRX-HD10 provides 10 watts in the digital hybrid mode; the TRX-HD50 provides 50 digital hybrid watts and the TRX-HD100 is a 100-watt digital hybrid translator. Armstrong says higher hybrid power levels are achieved by adding a solid-state amplifier to the TRX-HD10.
The translators also can be used as analog-only translators at 30, 150 and 300 watts respectively for stations that have not yet begun broadcasting an HD Radio component.
