This transmitter operates with the new FCC-allowed 5000 Hz bandwidth for full fidelity and intelligibility. It is certified to operate in conjunction with optional / external audio processors and filters to further enhance quality, loudness and range. It has a modern synthesized frequency system, so that should a frequency change ever be necessary, it may easily be done by a qualified field technician without component changes or board-level work.
	High Quality The TR.6000 HQ 5.0 is the only such unit on the market permitted to broadcast under the FCC’s allowed 5000 Hz audio bandwidth rules, producing a brighter, more intelligible and farther-reaching radio broadcast. The transmitter’s processing circuitry manages the audio output, providing a level of quality never before possible from a 10 watt AM transmitter. High Efficiency The TR.6000 HQ 5.0 RF circuitry operates on “Class D” amplifier design, delivering its signal using 1/3 the electrical power of conventional transmitters of its kind. The resulting decrease in the size of the solar generator and battery systems lowers the cost to procure, operate and maintain radio systems employing the TR.6000 HQ 5.0. Defeat-able LED operation reduces power utilization even further. High Reliability The TR.6000 HQ 5.0 is the only transmitter of its kind on the market today that generates its signal using only two output devices. This critical design difference makes the transmitter much more reliable in operation than its predecessors. Because the TR.6000 HQ 5.0 components are sized for larger output levels, it runs cool and at a fraction of its capacity, even at 10 watts, extending its useful life. The transmitter’s RF, power, control and audio circuitry is protected by a fully regulated power supply, so reliability is further enhanced. High Flexibility TR.6000 HQ 5.0 can operate on any AM frequency – even those with 9 kHz spacing – without a crystal change. A technician can modify its frequency on the bench, conveniently. The unit can mount in a 19” rack, on a panel or on a shelf, allowing TR.6000 HQ 5.0 to operate in virtually any physical environment. Its compact size – just one rack-unit in height – and light weight, allows it to be installed almost anywhere. High Functionality TR.6000 HQ 5.0 includes all the functions you expect in one package. Convenient external front panel controls include a LED wattmeter and modulation meter, power and modulation level controls, power and meter switches, monitor speaker and external on/off relay controls. This transmitter is capable of precision RF output using its on-board oscillator or via a reference port that admits an external 10 Mhz signal for additional stability and/or multi-transmitter synchronization.
