The TKR-750 Base Station/Repeaters are a basic, self-contained 25W continuous duty rack mount base station/repeater. The TKR- 750 is a VHF model, 25-50 Watts adjustable power. This is a 19 rack mount design, with rear access to an external speaker output (4 @ audio), accessory/logic controller connector (25 pin) and test-speaker-AUX connector (15 pin). The TKR-750/850 features wide/narrow channel spacing per channel and has programmable AUX Input/Output functions. This base station/repeater features DSP processed QT/DQT and companded audio (in simplex base operation).
