The edge marker was drawn outward from the canvas edge, so every one of its three line segments fell outside the clip and nothing rendered. Measured at a typical 320 px width: 0 of 3 segments visible on either side. That is the one case the marker exists for - an out-of-window tone is absent from this picture by definition, so with the marker clipped away the operator has no signal at all that a shift is happening. Which is what was reported. It is now a solid bar along the edge the tone lies beyond, plus a chevron whose arms open inward from it, so the whole marker sits inside the clip while still reading as pointing off-picture. Three further defects in the same code: The frequency label was pinned to TopStart while its background rect tracked the tone's frequency, so at 1500 Hz the rect sat at x=278 and the text at x=11. The rect is gone and the label now sits on whichever side the marker is on. Markers were drawn after two early returns that fire on an empty or silent spectrum. A shift is deliberately held through key-up gaps, so the markers were blinking out during the very silences the shift survives. They now draw unconditionally, after the spectrum so it cannot bury them. dashCount floored, leaving up to 8 px of the column undrawn at the bottom. Also extracts the marker drawing into a DrawScope extension, hoists the shared colours and the target frequency to file-level constants, and rounds the label instead of truncating it.
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.
