Direct local observations
WeatherLink Live data is read over the LAN. Discovery can be configured, but no special WeatherLink Python library is required.
Stale-data cutoff
The station timestamp controls freshness. After 12 hours without a valid response, all public products switch to the no-weather message.
Estimated cloud layers
GFA cloud layers are labeled AWC Estimated, cached, locked against overlapping jobs, and requested no more than every 30 minutes.
One snapshot, three outputs
The same observation and cloud cache generate the spoken WAV, text advisory, and PNG.
Noise-relative click detection
HackRF and Airspy backends calibrate to the local noise floor and apply click timing, request windows, and cooldown.
USB-relay radio control
The current path pauses SDR receive, closes the radio PTT contact, plays ALSA audio, releases PTT, and resumes receiving.
Configurable playback
Choose the ALSA output, PTT lead/tail, timeouts, and master playback volume. The current example begins at 85%.
Optional multi-channel listening
One wide HackRF sample can expose nearby configured airband channels for local live listening.
Optional recorded activity
Store primary-channel WAV clips and JSON metadata. Auxiliary capture can be gated by user-configured aircraft in recent local ADS-B data.
Sunrise-aware email
Send once per day after local sunrise plus ten minutes with weather, camera, request times, health, disk warning, and NBM guidance.
Public defaults stay generic
No real credentials, aircraft, email addresses, hardware serials, or private copy destinations belong in the committed configuration.
Regression tests
Automated tests cover weather freshness, cloud request limits, sunrise scheduling, recording, and both transmission paths.
What is not bundled here
The deployment-specific local aircraft/dashboard application is intentionally outside this core GitHub release. Full MyAWOS exposes the files, logs, sockets, and metadata that a separate local UI can consume without making the radio/weather engine dependent on a web application.
