* Fri Oct 22 2021 Martin Hauke - Update to version 4.0.0
* RTLSDR-Airband is now built with CMake.
* New output type udp_stream for sending uncompressed audio to another host via UDP/IP (thx AATTcharlie-foxtrot).
* Added multiple_output_threads global option. When set to true, a separate output thread is spawned for each device.
* Modulation in scan mode is now configurable per channel.
* SoapySDR errors like TIMEOUT or OVERFLOW are no longer treated as fatal. They often appear intermittently, especially when the CPU usage is high. There is no point in failing the input in this case.
* Added .tmp suffix to the names of the output files currently being written to. The suffix is removed when the file is closed. External applications that consume recorded files can now figure out which files are not yet complete.
* Added logging and statistics for output thread overruns and mixer input/output overruns (thx AATTcharlie-foxtrot).
* Miscellaneous bug fixes and code cleanups. BACKWARDS-INCOMPATIBLE CHANGES:
* Improved squelch algorithm with new configuration parameters. squelch keyword has been replaced with squelch_threshold which takes an absolute signal value in dBFS as an argument. Alternatively, a minimum signal-to-noise ratio (in dB) that should trigger the squelch might be configured using squelch_snr_threshold option (thx AATTcharlie-foxtrot).
* include_freq config option for file outputs now causes the frequency to be appended after the timestamp rather than before it. This feature now works correctly in scan mode, when split_on_transmission feature is enabled.
* sample format in files produced by rawfile outputs has been changed from CS16 to CF32. File name suffix is now .cf32.
* Improved squelch indicator in the textual waterfalls. In addition to the
* character indicating that the squelch is open, there is also a ~ character indicating that the channel has a signal that is being suppressed because it is outside the band of the channel filter.- Drop patch:
* rtlsdr-airband-fix-makefile.diff- Add patch:
* rtlsdr-airband-set-config-path.patch
* Sat Nov 14 2020 Martin Hauke - Update to version 3.2.1
* Fixed a compile error when using libshout older than 2.4.0
* Mon Nov 09 2020 Martin Hauke - Update to version 3.2.0
* Added split_per_transmission output file option which allows creating a new file for every transmission on the channel.
* Added include_freq output file option, which causes the channel frequency to be appended to the file name.
* Added support for notch filters for eliminating narrowband interference, like CTCSS tones.
* Added bandwidth channel option which causes the channelized I/Q signal to be lowpass-filtered before demodulation. This might help in situations where neighboring channels are closely spaced and interfere with the channel of interest. It also reduces the bandwidth of the resulting audio signal, and thus eliminates the high-frequency noise.
* Added support for multithreaded demodulation. Each device can now have its own demodulation thread. This allows spreading the demodulation work across multiple CPU cores. Enable with multiple_demod_threads global option.
* Added support for highpass/lowpass MP3 filters for mixers.
* Added support for frequency usage statistics.
* Workaround for Fitipower tuner problem of not honoring the first gain setting when the device is first used.
* Finalize the MP3 file properly before opening a new one.
* Close the RTL device properly on program exit.
* Updated the SoapySDR input driver to reflect changes in SoapySDR library API.
* Minor cleanups.
* Mon Jan 20 2020 Martin Hauke - Update to version 3.1.0
* SoapySDR: added support for complex float 32-bit samples
* SoapySDR: allow using AGC if the device supports it. Gain setting for soapy devices is now optional - if it\'s not specified, the program will try to enable AGC.
* Use lowpass/highpass filters provided by LAME library to improve audio quality of MP3 streams. Filter cutoff frequencies may be configured per output, using highpass and lowpass config options.
* Added log_scan_activity global config option. When set to true, a log message is written whenever a squelch opens on a scanned channel, effectively producing a channel activity log.
* Improved squelch behaviour in some corner cases.
* Fix for incorrect naming of pulseaudio context. Name set in the config was not used as it should.
* Don\'t fail when the configured gain value is negative. Some SDRs support this (eg. FC0012-based dongles).
* Fix a bug which in some cases could prevent the icecast output from reconnecting with the Icecast server after the connection has failed.
* Fri Feb 16 2018 mardnhAATTgmx.de- Update to version 3.0.1
* Fix for squelch staying constantly open when configured manually with NFM=off (#84)- Update to version 3.0.0
* Major overhaul of the SDR input code - now it\'s modular and hardware-agnostic (no longer tightly coupled with librtlsdr).
* Support for SoapySDR vendor-neutral SDR library - any SDR which has a plugin for SoapySDR shall now work in RTLSDR-Airband.
* Support for Mirics DVB-T dongles via libmirisdr-4 library.
* Support for RTLSDR is now optional and can be disabled at compilation stage.
* Removed the 8-channels-per-device limit in multichannel mode.
* Configurable per-device sampling rate.
* Configurable FFT size.
* Support for multibyte input samples.
* Support for rawfile outputs (ie. writing raw I/Q data from a narrowband channel to a file for processing with other programs, line GNUradio or csdr).
* INCOMPATIBLE CHANGE: removed `rtlsdr_buffers` global configuration option; buffer count can now be adjusted with a per-device \"buffers\" option.
* INCOMPATIBLE CHANGE: removed `syslog` global configuration option; syslog logging is now enabled by default, both in foreground and background mode. To force logging to standard error, use -e command line option.
* Added -F command line option for better cooperation with systemd. Runs the program in foreground, but without textual waterfalls. Together with -e it allows running rtl_airband as a service of type \"simple\" under systemd. Example rtl_airband.service file has been adjusted to reflect this change.
* Added `type` device configuration option. It sets the device type (ie. the input driver which shall be used to talk to the device). \"rtlsdr\" is assumed as a default type for backward compatibility. If RTLSDR support has been disabled at compilation stage, then there is no default type - it must be set manually, or the program will throw an error on startup.
* Frequencies in the config can now be expressed in Hz, kHz, MHz or GHz for improved readability.
* Lots of bugfixes.- Update to version 2.4.0
* Support for PulseAudio output via new output type `pulse`. With this feature you can eg. play the sound via the soundcard of the Raspberry Pi you run RTLSDR-Airband on (you need to install and run pulseaudio daemon on it, though). Or you can stream the audio from a Pi located near the antenna (eg. in the attic) to speakers connected to the desktop PC you are sitting at, without launching a local Icecast server, as before. Because the audio stream is sent uncompressed, it is not recommended to run it across the Internet - jitter or packet loss will easily cause the audio to become choppy. However in a local network PulseAudio is a good choice. And it gives much lower latency as compared to Icecast (typically under 0.5 seconds). Thanks to Marcus Ströbel for the idea and initial implementation.
* Support for referring to RTL devices by their serial numbers in the config file. Instead of `index = ` parameter, use `serial = ` to get consistent behavior across reboots and hardware reconfigurations.
* Set RTL gain to the nearest gain value supported by the device. This is required for E4000 tuners, which do not round the given gain value to the nearest supported setting, which causes the gain setting operation to fail.
* Improved squelch operation in scan mode. All squelch-related variables (noise floor, AGC coefficients, etc) are now calculated and stored separately for each scanned channel. Earlier their values were common to all channels, which caused squelch problems in case when noise floor varied considerably between channels. Thanks to AATTstrix-technica.
* Added build target for FreeBSD on x86. Use `PLATFORM=x86-freebsd` to compile and `PLATFORM=x86-freebsd gmake install` to install. Thanks to AATTnyammy.
* Display squelch setting in waterfall in place of noise floor value when squelch is set manually.
* Bug fixes, performance improvements.
