The DX 7500 Series Aeronautical Base Stations are rugged, state-of-the-art DSP (Digital Signal Processor)
based units which are designed to meet the existing (US) 25 kHz channel requirements and the new 8.33 kHz
international requirements. These versatile products can be configured as a (direct) locally controlled unit with
(desk) microphone and internal speaker; in this configuration all functions and operation are identical to those
of the 7010 mobile unit, except the power output, which may be 10, 100 or 200 Watts (PEP). The DX 7500 Series Aeronautical Base Station can also be configured as a locally controlled unit with E & M interface or “Tone Remote”.
