  • Transparent S Meter Posted 2 weeks ago
    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 3 weeks ago
    Download here [Link]. What's new / changed in 3.0.13: General Fixed frequency display problem in the RDS display. 100.05 was displayed as 100.5. 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 ...

    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.
  • S-Meters Posted 3 weeks ago
    After much pestering by users, I finally added an Analog S-meter to SDR Console. These will be available in 3.0.13, coming to a desktop near you soon. Background A few weeks previously a reasonable logic was implemented for measuring the noise floor. Purists will not be happy, but they rarely are, but it works for me. Take the output from the SDR radio, ignore 15% of the bandwidth at the high and low end of the output to avoid the ant-alias filtering, and we're left with a healthy 70% of the signal. Now sort the FFT bins by value, take the mean of the lowest 10% and that's the noise floor. Digital Starting with the standard digital metere: Analog Here are a few screenshots of the Analog S Meter. First a tradition meter in S units. Red = peak signal Yellow = current signal Grey = noise floor   Here's a dBm meter, same colours as above.   And here.s a Signal to Noise (SNR) meter.
  • Pluto on Es'Hail 2 Posted last month
    Here's a screenshot of my Pluto SDR on Es'Hail 2, this screenshot shows the suggested settings for pluto(bottom left-hand side). Note the RX Gain is set to Slow Attack (Manual value is ignored) and the Visual is set to -40dB.
