AR5700D Digital Communications Receiver

AOR AR5700D Digital Communications Receiver – 9kHz to 3.7GHz Advanced Signal Intelligence Solution

Overview

The AOR AR5700D Digital Communications Receiver stands at the forefront of professional radio monitoring technology.
Covering a wide frequency range from 9 kHz to 3.7 GHz, this state-of-the-art receiver delivers unparalleled signal detection, digital voice decoding, I/Q recording, and wideband monitoring capabilities for commercial, government, and intelligence applications.

AOR has enhanced this receiver family including the AR5700D, AR2300IQ, AR5001D (with IQ5001), and AR6000 (with IQ5001) to include advanced GSSI user group filtering for TETRA trunked networks.
This breakthrough feature allows operators to import, bookmark, and identify TETRA network user groups, and selectively decode their voice communications—a world first in communications receivers.

Unmatched Digital Decoding Capabilities

The AR5700D is designed for today’s complex radio environments, supporting both digital and analog modulation formats across multiple standards.

It decodes a wide array of digital communication protocols, including:

• TETRA (Direct mode and Trunked mode with GSSI filtering)
• DMR (Tier 1 & 2)
• NXDN (with 15-bit descrambling)
• D-STAR
• dPMR
• APCO P25 Phase 1
• YAESU C4FM, ALINCO EJ-47, and D-CR

In addition, it receives traditional analog modes such as FM, AM, Synchronous AM, FM-Stereo, USB, LSB, CW, Analog I/Q, and FM video.
Whether monitoring trunked public safety channels or conventional analog transmissions, the AR5700D provides total decoding flexibility.
