Assorted ramblings from the developer


Release: 3.0.2

Performance

Some of the early V3 code was not as efficient as it should have been - the Windows message pump was working too hard. Messages have been replaced with callacks and high-precision timers, as a result performance and CPU load on lower-powered computers such as the Core2Duo and mobile CPUs has improved, sometimes quite dramatically.

Additions / Fixes

  • Added Favourite Definition Groups. You can now have up to 5 optional sets of Favourite definitions as well as the Default. More below…
  • Added single-tuner RSPduo support.
  • Changing spectrum colours now updates the RX DSP pane if the pane is floating.
  • Latest HF+ library now in use.
  • Issues clicking on main window splitter causing areas of the display to go white (not be painted) resolved.
  • Fixed issues setting recording options via the Program Options.
  • Reduced Airspy / Airspy HF+ latency.
  • Satellite custom name definitions can now be undone.

Outstanding Bugs

  • Restarting doesn’t restore the filter width, this always reverts to the default for the last used mode.

 

Favourite Definition Groups

Select from the Defns panel in the ribbon bar, Defns is only shown if you have enabled one or more definitions groups.

In the Organiser select the Definitions, click … to define groups (top of window, see below).

  • Release: 3.0.15 Posted 3 days ago
    Download here [Link]. What's new / changed in 3.0.15: General Added AM, SAM  and BFM independent sideband tuning (asymmetrical filtering) Filter low and high sides are optionally independent, the default is (and was) that the filter is symmetrical. In the Filter window added a new button, when highlighted Independent tuning is enabled. The text in this button will change when I have a better idea! When switching from ISB to Symmetrical filters take the greater of low & high and apply to both sides.   Markers now support alternate colours for DX spots. Memories Organiser now correctly processes ^ and v buttons when more than one entry is selected. Updated the Serial port PTT: Should have anti-bounce logic, bounces < 100ms should not affect TX More diagnostics available using DebugView.   Added 40, 50 and 60 minutes to the DX Cluster options. Fix problem with scheduled recordings and WAV / RF64 setting (multiple  / single files). Added MIDI support for some TX ...
  • Release: 3.0.14 Posted 3 weeks ago
    Download here [Link]. What's new / changed in 3.0.14: General Closing threads (and the program) now much faster if the thread had not been started, also System Debugger diagnostics have been enabled to find any other issues when closing the program if the ‘Not Responding’ text was seen in the title bar. Fixed bug where a high-pass filter could be incorrectly applied to broadcast FM demodulation. RDS logfile now supports UTC as set in the … Options window. Geostationary beacon window now applies the current contrast when floating. Receive audio equaliser now correctly initialised when started from either: Audio dropdown, Ribbon bar. FM Squelch: big change on the FM squelch front: Now suing power suqelch instead of noise squelch, the squelch threshold/level values will be different, sorry about that. The original code was over nine years old and was a cheap and cheerful solution. In the kit the whole concept has changed, now it’s an advanced squelch based on signal power. Synchronous AM, ECSS Lock Range: ribbon bar entrry added. ...
  • Transparent S Meter Posted last month
    Version 3.0.13 introduced analog S meters and resulted in requests for transparency. One of the big features of SDR Console is the use of Direct2D graphics which is a lot more complicated than the GDI/GDI+ used in many other ham radio programs such as Ham Radio Deluxe. Working out transparency wasn't easy, finally a Microsoft example showed me how to do this. A day when you don't learn something is a day wasted. Here's an example of transparency. This will be part of 3.0.14.
  • Release: 3.0.13 Posted last month

Minor change to logic when closing the Matrix window, linked to a memory leak. Reduced background thread start-up time. Added Equaliser… option to the Playback device selection.   The Radio Selection windows displays Connect when a V3 Server is selected, otherwise Start. New option to replace 0 with O in the main frequency display.   Added Google Turbo and Inferno colour schemes.   Markers Memory definitions can now be shown as markers: new option in Markers dropdown and on the memories pane of the ribbon bar. Display of markers more efficient. Enhanced the marker display logic, allowed more room when markers overlap. Recordings Audio recordings made while playing an IQ recording are now timestamped with the time from the playback, not the current time. Added Status option to Playback pane in the ribbon bar. When selected the playback status is shown in the waterfall (the default). If not selected then playback status is not ...
  • Google Turbo Posted last month
    Turbo, An Improved Rainbow Colormap for Visualization  https://ai.googleblog.com/2019/08/turbo-improved-rainbow-colormap-for.html On Tuesday, August 20, 2019 Google posted an interesting colour scheme which they named 'Turbo'. Read more about this in the blog entry (link is above). Below is the colour map in action on the 25m shortwave broadcast band. As of 3.0.13 this is a standard colourmap[ in SDR Console. Also of interest is the use of a SNR (Signam to Noise) S Meter option.
