Micro Computer Concepts has manufactured and marketed repeater controllers for over 12 years. Now it is integrating its controllers with one of the best receiver/transmitters to form a ready to plug in repeater on your frequency, tuned and guaranteed. We want to make the repeater installation simple for the repeater owner; a plug and play system. You will need to add duplexer, antenna and 13.8 VDC power supply.

The receiver/transmitter unit is a GE Master Executive II mobile converted for repeater use. The GE Master Exec II receiver employs a five cavity helical input filter to insure out of band rejection. It was developed to work in the harshest RF environments. Unlike other repeaters which have transmitter noise only 60 dB down, the Master Exec II's transmitter is one of the quietest and cleanest with noise over 85 dB down allowing the use of less expensive duplexers (4 cavities instead of the usual 6). It was engineered to be a high performance receiver/transmitter unit for use in locations with other nearby transmitters.

The repeater can be ordered with a variety of Micro Computer Concepts controllers from the very basic of key transmitter on receiver input, to controllers with autopatch, reverse patch, voice, remote base interface and more. The repeater can also be ordered for use with other controllers. A DB15S connector is provided and includes the signals necessary for use with an external controller.

A special panel has been added with volume and squelch controls, speaker jack, LED indicators for power, push-to-talk, carrier-operated squelch and CTCSS detect, accessory DB15 connector and power connections.

To provide clean natural sounding audio a custom audio board is installed which de-emphasizes the audio at the EIA spec of rolling off at 6 db per octave and a high pass filter for removing incoming CTCSS tones.

MCC offers controllers and if ordered with repeater the control can be installed inside the repeater and all audio is adjusted. The repeater can also be ordered for an external control where the repeater inputs & outputs are brought out to the DB-15S connector on the front panel.

If CTCSS tone is needed MCC will install TS-64DS dip switch tone set encoder/decoder.
