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”.
In addition to the functions described above, the 7500 also features front and rear jacks for use with an aeronautical headset. Note: Some earlier versions of the basic 7500 do not feature “side-tone”. If side-tone is required, this option should be installed at the factory.
DX Radio’s 7500 Series Aeronautical Base Stations can be supplied with a variety of RF power levels, AC or DC power requirements and remote interface options. The standard unit is an AC operated unit with a single type “N” antenna connector.
For applications in RF dense environments, the 7500 can be configured with (optional separate) RX/TX antenna ports, or with a common Antenna I/O and RX filter “IN” and “OUT” connections. These configurations are for installations requiring RF combining and external RX filtering respectively.
Optional Modes of Operation
- Locally controlled base station
- Locally E&M controlled base station
- Tone-Remote controlled base station
- Dialup Tone-Remote controlled base station
- DC Operated Systems (including AC/DC Standby Systems)
