Repeaters

The TKR-750/TKR-850 is a synthesized, 50/40-watt commercial grade repeater. During over-temperature conditions, the power output is automatically reduced to 25-watts. The high power level is adjustable between 10 and 50/40-watts.

Standard Features:
DC battery backup switch-over in an event of a primary DC power failure.
The battery backup circuit includes a charge feature.
Built-in CTCSS and DCS.
Built-in DTMF decoder.
Programmable Station ID.
3-1/2″ Rack mount chassis.
16 programmable channels with Wide/Narrow channel spacing for each channel.
6 programmable function keys with front panel speaker and microphone jack.
Built-in cooling fan.
DSP audio processing.
