AWMyAWOS
Open-source airport weather

Weather when pilots ask for it.

MyAWOS turns local weather, aviation forecasts, an SDR receiver, and a connected radio into an on-demand spoken airport weather report.

From sensor to radio.

MyAWOS keeps acquisition, report generation, click detection, and transmission separate. That makes the installation testable in safe stages—and makes stale weather much harder to mistake for live conditions.

01

Observe

Read a local WeatherLink Live station and validate its own observation timestamp.

02

Enrich

Add rate-limited AWC GFA cloud guidance, clearly labeled as an estimate.

03

Generate

Build matching voice, text, and PNG products from the same weather snapshot.

04

Listen

Use HackRF or Airspy and a noise-relative detector to count the click sequence.

05

Transmit

Key a purpose-built radio with a dry-contact USB relay and play the current WAV.

06

Monitor

Receive a daily status report and optionally capture radio audio with metadata.

Current reference design

Clear paths. Fewer mysteries.

The SDR receives only. The aviation radio transmits. The USB relay closes PTT like a switch. Weather and cloud inputs remain visibly distinct all the way to the output.

Freshness first

Old weather never masquerades as current.

The station-provided observation time is authoritative. After 12 hours without a valid observation, the voice and graphic say “No weather available at this time” and omit the old values.

AWC Estimated means estimated.
Model cloud layers are cached, rate-limited to one attempt per 30 minutes, and kept separate from on-field observations.
