TR6000 Model 15.73 Transmitter TM
OLYMPUS DIGITAL CAMERA
The TR6000 Model 15.73 Transmitter can provide 10-watt emergency/reduced power service for a broadcaster under FCC Part 73/1560 or unlicensed, on-campus broadcast service for an educational institution under FCC Part 15.221.

FCC Certification Number B7MTR-6000TIS-WB.

High Quality
The TR6000 Model 15.73’s processing circuitry manages the audio output, providing a level of quality never before possible from a 10-watt AM transmitter.

High Efficiency
The TR6000 Model 15.73’s 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 size of the solar generator and battery systems lowers the cost to procure, operate and maintain radio systems employing the TR6000 Model 15.73. Defeat-able LED operation reduces power utilization even further.

High Reliability
The TR6000 Model 15.73 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 TR6000 Model 15.73’s 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
TR6000 Model 15.73 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 TR6000 Model 15.73 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
TR6000 Model 15.73 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.
