-------------------------------------------------------------------
Fri Oct 22 19:24:19 UTC 2021 - Martin Hauke <mardnh@gmx.de>
- 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 @charlie-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 @charlie-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 @charlie-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.

Sat Nov 14 16:12:03 UTC 2020 - Martin Hauke <mardnh@gmx.de>
- Update to version 3.2.1
* Fixed a compile error when using libshout older than 2.4.0
-------------------------------------------------------------------
Mon Nov 9 09:40:32 UTC 2020 - Martin Hauke <mardnh@gmx.de>
- 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 15:16:49 UTC 2020 - Martin Hauke <mardnh@gmx.de>
- 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 20:14:42 UTC 2018 - mardnh@gmx.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 = <dongle_index>` parameter, use `serial =
<dongle_serial_number>` 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 @strix-technica.
* Added build target for FreeBSD on x86. Use `PLATFORM=x86-freebsd` to
compile and `PLATFORM=x86-freebsd gmake install` to install. Thanks
to @nyammy.
* Display squelch setting in waterfall in place of noise floor value when
squelch is set manually.
* Bug fixes, performance improvements.
* Decluttered and more understandable documentation.
