When the tone-shift feature moves a tone into the model's 400-1200 Hz window, the waterfall now shows two visual markers so the operator can see what is happening: a green dashed line at the target (800 Hz) and an orange frequency label at the top-left showing the original pitch. The waterfall draws the RAW audio, not the shifted audio, so a 1500 Hz tone was always invisible regardless of the shift setting. The markers close the gap: the operator can now see that a tone was detected and where it was moved, even when the original pitch is outside the visible band. activeShiftHz is now a StateFlow exposed through ICwDecoder so the UI can observe it without polling.
Look4Sat: Satellite tracker
Radio satellite tracker and pass predictor for Android, inspired by Gpredict
Track satellite passes with ease!
Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.
Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.
The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.
Main features:
- Predicting satellite positions and passes for up to 10 days
- Showing the list of currently active and upcoming satellite passes
- Showing the active pass progress, polar trajectory and transceivers info
- Showing the satellite positional data, footprint and ground track on the map
- Custom TLE satellite data import is available via Three Line Element .txt files
- Offline first: calculations are made offline. Weekly TLE data update is recommended.
