SDRangel version 6 (master/v5 merge)
There has been evolution in the master branch recently that make the desire to keep an ultra stable master branch and fast evolving tip branch (v5) in fact obsolete and not desirable anymore. Moreover quite a few of these changes come from contributors who legitimately work from the master branch. So this is creating confusion and just extra work.
The recent addition of feature plugins would have deserved a new major release but was made a new minor release in each branch because of the split in master and v5. There are also new major features coming to master from v5:
- Upgrade to c++14 standard
- MIMO support including support for Metis devices (Red Pitaya)
- Websocket spectrum server
- Additional plugins:
- ChirpChat (LoRa extension) modulator/demodulator
- SigMF file support when compiled from source
The v5 branch is kept for reference
Other news, changes and fixes
Audio input plugin
Another nice contribution from Jon srcejon to take the I/Q input from an audio device. This makes it possible to work with first generation audio "card" based SDR devices such as the SoftRock or more sophisticated ones. Details here
ADS-B enhancements
More enhancements and fixes to the ADS-B demodulator by Jon srcejon:
- Add decode of Mode-A transponder (Squawk) code
- Add decoding of surface position messages (so you can see aircraft position at airports)
- Add Az/El and distance to airport information box
- Require double click to set ATC frequency.
- Allow airport to be set as target, by double clicking Az/El in airport info box.
- Confirm redownload of files if less than 100 days old.
- Add option to automatically resize columns after an aircraft is added to the table.
- Check latitude and local CPR decode is in valid range (to prevent aircraft from jumping around the map).
- Reduce interpolator taps to enable it to run in real-time. Should significantly improve packet error rate for RTLSDR at 2.4MSa/s.
