On FM satellites the grid is the exchange - it is what the other station sends you and what you send back. Until now it could only arrive by scraping QRZ, which needs a cookie the operator may not have pasted, and which returns nothing at all for a station with no locator on file. So the field that carries the actual content of an FM contact was the one field the operator could not fill in. It is the second field, optional, six characters, uppercased. A typed grid also skips the QRZ lookup entirely rather than racing it: what the operator heard on the air beats what a web page says, and letting the scrape overwrite it would silently replace good data with a guess. The value is captured before the field clears, so the QSO carries it and the next contact starts empty. WavelogQso.gridsquare already existed for the scraper to fill, so nothing about the stored shape changes and no migration is needed. This was the interaction study's second-ranked conclusion, after the editable time. Both come from the same observation: the screen was built for someone typing during a pass, and the operators it is for are working the radio instead.
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.
