822-1468-102 – Collins Aerospace VHF Communications Transceiver VHF-4000
Available now on the Airparts.aero Marketplace.
Overview
The Collins Aerospace VHF-4000, part number 822-1468-102, is a state-of-the-art, all-digital VHF communications transceiver, representing the standard for reliable voice and data communication in modern business and commercial aircraft. This unit is a core component of the Collins Pro Line 21™ and Pro Line Fusion® integrated avionics suites. It is engineered to provide superior performance, exceptional audio clarity, and compliance with the most stringent global air traffic control requirements, including 8.33 kHz channel spacing. As a remote-mounted Line Replaceable Unit (LRU), it is designed for high reliability and seamless integration with the aircraft's flight deck controls and displays.
Key Features
- 8.33 kHz Channel Spacing: Fully compliant with European mandates for 8.33 kHz channel spacing, effectively tripling the number of available VHF voice channels. This capability is essential for unrestricted operation in congested European airspace.
- Digital Signal Processing (DSP): Utilizes advanced DSP technology to provide crystal-clear voice communication with unparalleled clarity and noise rejection. The digital architecture ensures stable, drift-free performance.
- VDL Mode 2 Capability (Optional): This unit is capable of supporting VDL (VHF Data Link) Mode 2 operations, which is the foundation for digital data link communications like ACARS (Aircraft Communications Addressing and Reporting System) and certain FANS (Future Air Navigation System) functions.
- Pro Line® Integration: Designed for seamless "plug-and-play" integration with Collins Aerospace integrated flight decks. Frequency selection, audio control, and system status are all managed through the primary cockpit displays and control units.
- High Reliability & Compact Design: Engineered with advanced solid-state components for a high Mean Time Between Failure (MTBF). Its compact and lightweight design makes it ideal for efficient use of space in the avionics bay.

The Collins VHF-4000's implementation of 8.33 kHz channel spacing is a direct response to VHF frequency congestion. In this system, the 25 kHz bandwidth of a single legacy channel is split into three distinct 8.33 kHz channels. A digital radio like the VHF-4000 is able to precisely tune to these narrow channels and filter out adjacent channel interference, a task that older analog radios cannot perform. Its VDL Mode 2 capability further enhances its function by using a packet-based data protocol, allowing multiple users to share a single VHF frequency for short data burst transmissions, which is a far more efficient use of the spectrum than voice communication for routine messages.
Note: This is a flight-critical avionics component. Installation, configuration, and testing must be performed by a certified Part 145 repair station or a qualified avionics technician in strict accordance with the manufacturer's installation manual and all applicable airworthiness regulations. Proper configuration of the radio is essential for legal operation.
