This uses the corresponding function in the librtlsdr interface (range -99..99 ppm) - - Added a preset update button (the diskette with the yellow corner) to be able to save the current settings on an existing preset - - Added variable decimation in log2 increments from 2^0=1 to 2^4=16 allowing to see the full 2048 kHz of spectrum if so you wish - - Better handling of rtlsdr GUI display when settings change (initial load, load of presets) - - Added display and precise control of the shift frequency from center frequency of the NFM receivers. - - Removed useless spectrum visualizer in NFM receivers. Created a null sink class to fit corresponding parameter in NFMDemod class constructor. - - Added display and precise control of the shift frequency from center frequency of the SSB receivers. - - SSB filter bounds are tunable so that filter can be set off from center frequency allowing aural decoding of CW - - Make the sidebands appear correctly on SSB channel overlay. Limit to +/- 6 kHz to fit channel spectrum analyzer window - - SSB bandwidth can now be tuned in steps of 100 Hz - - NFM and SSB receiver in focus trigger the display of the central frequency line on the spectrum frequency scale thus facilitating its identification - - Added AM demod so now you can listen to air traffic! - - Added the possibility to change the brightness and/or color of the grid. - - Make the low cutoff frequency of the SSB filter variable so it can be used for CW also. - - NFM demodulation without using atan and smooth squelch with AGC suppressing most clicks on low level signals and hiss on carrier tails. Only useful modulation comes through. - - Added working WFM demodulation. Optimized for no atan2. - - OsmoSDR and GNURadio plugins removed from the build as they have too many bugs that are too difficult to correct - - New plugin for BladeRF interfacing libbladeRF directly - - Corrected the nasty audio band resampling bug preventing use of sample rates that are not power of 2 multiples of 48kHz. This was because the resampling ratio was calculated with an integer division instead of a float division. - - As a consequence of the above added more interesting values for the available sampling rates of the BladeRF plugin - - Variable span for the SSB demod down to 1.5 kHz - - Filter out CTCSS tones for audio and full CTCSS support in NFMDemod - - Enhancement of the NFM squelch mimicking professional analog squelch circuits (based on balance between two AF filters) - - Added a channel analyzer plugin focusing on measurement (DSA/DSO functionnality). Basic functions. - - Added a scope widget in the channel analyzer plugin - - Channel analyzer bandwidth up to half the available RF (IF) bandwidth (was 48k fixed) - - Enhanced scope display and controls: scale display, better X (time) and Y scales control, grid fit to scale, effectively implementing triggers, trigger on magnitude and phase, properly handling time shift, ... - - Enhanced spectrum display: Histogram: wider decay range, make stroke and late holdoff adjustable. Added option to show live spectrum (had only max hold before). - - Enhanced channel analyzer: enhanced scope and spectrum displays as mentioned above, make the spectrum display synchronous to scope (hence triggerable a la E4406A). - - Sort channel plugins by delta frequency and type before saving to preset - - Implemented scope pre-trigger delay - - Implemented variable scope memory depth - - Implemented trigger delay - - Trigger on both edges - - Spectrum histogram clear - - Trigger line display for all trigger modes - - Coarse and fine trigger level sliders - - Minimalist recording (no file choice) - - File sample source plugin (recording reader) - - Scope: trace history - - Scope: trigger countdown - - Scope: multiple trigger chaining - - Scope: new mode with linear IQ (two traces) on the primary display and polar IQ on the secondary display - - New USB source plugin to connect to an external demodulator (ex: GNU radio) via USB ports - - Binaural option for SSB demod - - DSB option for SSB - - Mute option for NFM channel - - New Broadcast FM demodulator with stereo support - - RDS support in Broadcast FM demodulator - -<h2>Major redesign</h2> +See the v1.0.1 first official relase [release notes](https://github.com/f4exb/sdrangel/releases/tag/v1.0.1) - - Make the DSP engine global static simplifying access to it. Have a distinct object to handle the thread - - Fixed startup initialization sequence. New initialization phase in DSP engine and new ready state - - Synchronous messaging class to push message to thread and wait for completion relieving the message queuing mechanism from this role - - Message queuing and handling redesign. Still not completely satisfactory - - Objects have their own input and output message queues - - Dedicated message queue to communicate to the GUI for objects coupled with a GUI - - Optimizations with Valgrind cachegrind - - Corrected decimators bit shifting so that the number of effective output bits is constant and fill the internal sample width - - Separate library to support all flavours of FunCube dongles. Rewritten FCD plugins. - - Allow several sample source plugins to share the same presets for what is common - - Prepare grounds for future Tx operations with Tx spectrum display in the main window - - Merged include-gpl into include and removed GPL dribble in About dialog - - Many other little things... - -<h1>To Do</h1> +<h2>To Do</h2> - Allow the handling of more than one device at the same time. For Rx/Tx devices like the BladeRF Rx and Tx appear as two logical devices with two plugin instances and a common handler for the physical device services both plugins. This effectively opens Tx support. - Tx channels - Possibility to connect channels for example Rx to Tx or single Rx channel to dual Rx channel supporting MI(MO) features like 360 degree polarization detection. @@ -227,4 +163,4 @@ The release type can be specified with the `-DBUILD_TYPE` cmake option.
