ADS-B receiver troubleshooting
Start with symptoms, measure before changing anything, and make one reversible change at a time.
Poor ADS-B receiver range
Improve antenna height, coax loss, gain and line of sight.
Low ADS-B message rate
Diagnose gain, overload, USB stability and decoder health.
ADSB feeder offline
Restore forwarding, networking and receiver services safely.
Measurements that matter
- Aircraft and messages per second at comparable times of day.
- Maximum range by direction, not one exceptional aircraft.
- Signal distribution and percentage of strong messages.
- Service uptime, USB errors and forwarding connection state.
