AOR AR-DV3 100kHz – 3000MHz Professional Communications Receiver

The AOR AR-DV3 is a compact, high-performance wideband receiver designed for monitoring both analogue and digital signals from 100 kHz to 3000 MHz. Combining extensive frequency coverage with advanced digital voice reception, the AR-DV3 is ideal for amateur radio enthusiasts, communications monitoring and anyone looking for a versatile desktop receiver in a small footprint.

The AR-DV3 supports a wide range of analogue modes, including CW, SSB, AM, synchronous AM, FM and WFM, as well as popular amateur radio and commercial digital systems, including TETRA, P25, DMR, NXDN, dPMR, D-STAR, D-CR and YAESU digital modes. Automatic analogue and digital mode detection selects the appropriate demodulation mode, IF bandwidth and channel step based on the tuned frequency, making operation straightforward even in busy RF environments.

A newly developed RF front end incorporates a 14‑segment HF/VHF/UHF band‑pass filter for improved suppression of unwanted out‑of‑band signals, while a SAW filter in the IF stage enhances adjacent‑channel interference rejection. For rapid frequency discovery, the receiver offers two selectable high‑speed search modes: standard high‑speed search up to 100 steps per second in FM mode, and CYBER SEARCH, which scans up to 600 steps per second (depending on the tuning step).

Audio performance is boosted by a dedicated audio DAC, a low‑noise headphone amplifier, and a wide‑band, flat‑response speaker. A built‑in on‑screen audio equaliser lets you tailor the sound to your preference, while AM noise reduction improves clarity on weaker signals. The AR-DV3 also supports USB Audio Class 1, providing plug‑and‑play digital audio connectivity to a Windows PC and direct compatibility with decoding software, eliminating the need for virtual audio cables. An optional Digital I/Q output module enables operation with SDR# for spectrum visualisation and advanced demodulation.

For convenient data management, the receiver includes an SDHC card slot for audio recording with logs, memory backup and firmware updates. Free AOR utility software can be used to manage memory channels, banks and search groups. Power can be supplied from a conventional 12 V DC source or via USB‑PD at 15 V (30 W or higher), making the AR-DV3 suitable for both fixed‑station use and portable operation with a compatible USB‑PD power bank.
