What changed in 1.7.41
- Event clips now follow your alert classes: a clip is saved only when an alert you have switched on would fire, instead of for every burst a receiver reports.
- TinySA sweep ranges now take reliably, including wide ranges such as 0 to 5300 MHz. Start and stop are applied together and the panel confirms what the instrument is actually sweeping.
- Radios always sit at the top of the receiver stack, with a TinySA below them and the radiation strip at the bottom.
- The receiver log is capped at 10 MB with one rollover file, and an oversized log from an earlier version is trimmed automatically on first run.
- The channel activity alert tone no longer repeats back to back on a busy channel.
