Capability
Communication & Navigation
Comm and nav equipment repaired at board level — including receivers that are no longer supported by the people who built them.
Overview
What we see, and what we do.
Radios fail in ways that are easy to misattribute. Weak transmit gets blamed on the antenna, receive noise on the aircraft's bonding, and an intermittent on whatever was touched last. The unit itself is often the simplest thing to rule in or out on a bench with the right equipment.
A lot of this equipment is a generation or two behind current production and none the worse for it. Where a receiver still meets its specification, keeping it serviceable is a better decision than replacing a panel to solve one fault.
Equipment We Service
- VHF Communication Transceiver
- HF Transceiver
- VOR / ILS Navigation Receiver
- Glideslope Receiver
- Marker Beacon Receiver
- Automatic Direction Finder
- Distance Measuring Equipment
- GPS Receiver
- GPS / WAAS Navigator
- Audio Panel
- Intercom Amplifier
- Radio Altimeter
Faults We See Most
- Weak or distorted transmit reported by ATC
- Receive noise, squelch or breakthrough
- Intermittent operation with vibration or temperature
- Navigation flag in view with valid signal
- DME failing to lock or dropping out
- Audio panel channel dead or crosstalking
Recognise one of these? Describe what was observed rather than what you think has failed — it is frequently a different unit.
Common Questions
Communication & Navigation,
asked in practice.
- ATC says my transmit is weak. Is it the radio or the antenna?
- Either, plus the coaxial run and its connectors between them. A bench test on the transceiver establishes whether it makes rated power, which either identifies the unit or clears it and points you at the installation.
- Is it worth repairing an older navigation receiver?
- If it still meets its specification, yes. Being a generation behind current production is not a fault. Replacing a working receiver usually means disturbing an installation that is behaving, which introduces risk you did not have.
- The fault only shows up in flight. Can that be found on a bench?
- Often. Faults that appear with vibration or temperature are reproducible under those conditions deliberately applied. A unit that tests fine once at room temperature has not been cleared — it has been tested at the one condition where it works.
