AOR LTD

What AOR LTD does

AOR LTD is a Japanese specialty communications equipment manufacturer founded in 1977 and headquartered in Tokyo, designing and producing wideband radio communications receivers and quartz crystal/frequency control components. The company's core products are software-defined radio (SDR) receivers capable of standalone decoding of multiple digital voice protocols (TETRA, DMR, NXDN, D-STAR, dPMR, APCO25, Yaesu, Kenwood, Alinco) without requiring a connected PC, spanning the AR-DV handheld/desktop series, the high-end AR5700D, AR6000, AR5001D, and AR2300 base/rack receivers, plus direction-finding models (AR-ONE-C). The product line is complemented by RF front-ends (RF-6G), antennas (DA series discones), accessories (ARL2300 Ethernet controller, IQ5001 I/Q option, GT-1MK2 galvanic isolator, LN4000 LNA), add-on decoder modules (ARD300), a crystal products division, and contract manufacturing/R&D services.

The company's technology is built on a proprietary digital signal processing architecture with premium analog components (e.g., LTC2205-14 ADC delivering -140 dBFS noise floor on the AR5700D) and integrates deeply with the Airspy SDR# and SPYSERVER ecosystem for I/Q streaming, recording, and remote access. Notable engineering milestones include the world's first standalone wideband receiver to decode trunked TETRA traffic channels (AR-DV1) and the world's first handheld receiver with an optional COSPAS-SARSAT distress beacon decoder (AR-DV10).

AOR sells primarily through a global authorized distributor network (PROSIC in France, Moonraker in UK, Goldstar Security in Korea, plus coverage in Poland, New Zealand, Hungary, Russia, and Singapore) and a wholly-owned U.S. subsidiary (AOR U.S.A., inc.) that operates a direct e-commerce storefront. Revenue streams comprise hardware sales (receivers, antennas, RF front-ends, crystal products), software/option license keys (e.g., TETRA GSSI activation, COSPAS-SARSAT activation, I/Q upgrade options), and professional services (contract manufacturing, R&D, component sourcing). Pricing is quote-based and not publicly disclosed. The customer base spans government agencies, defense, broadcast, transportation, aerospace, amateur radio operators, and electronics industry system integrators.
