Aviation VHF Receiver Redesign: End-of-Life Issues Solved, Zero Field Failures in 10+ Years
An aviation company had a legacy VHF receiver going end-of-life with incomplete documentation and no clear path forward. A receiver redesign was needed.
Dealing with obsolete components or an aging product design? We’ve been redesigning RF electronics for long-life production since 2006.

The Problem
An aviation communications company had a legacy VHF receiver that was reaching end of life. Key components were going obsolete, and the original design documentation was incomplete. They needed a new long-life receiver redesign that matched or exceeded the performance of the existing product, with a BOM that wouldn’t become obsolete again within the product’s expected service life.
Our Approach
We started by reverse-engineering the existing receiver to write a complete specification from the working product. From that spec, we generated a new design optimized for longevity. We leveraged our internal knowledge base of end-of-life histories with various component vendors to select parts with long projected availability, which was critical for a product that needed to stay in production for a decade or more. Beyond the design itself, we also handled fabrication and test of the final subassemblies, providing a complete turnkey solution.
The Result
The new VHF receiver design was completed in a single pass. All specifications were met except for one radiated spur, which was eliminated with a few targeted ferrite beads. The design was released to production and ran for over 10 years with zero reported field failures. The carefully selected BOM remained fully available throughout the product’s life, exactly as planned.
