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.

Turbo, An Improved Rainbow Colormap for Visualization
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.
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.
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.
Starting with the standard digital metere:
Here are a few screenshots of the Analog S Meter.
First a tradition meter in S units.
Here's a dBm meter, same colours as above.
And here.s a Signal to Noise (SNR) meter.
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.
Yesterday I powered on a small ATOM 330 server which was last started five years ago. Well, up came Windows 7 Professional and of course the normal zillions of updates appeared. Anyway, I wondered whether the now officially expired free update from Windows 7 to Windows 10 was still available. Google brought me to this link on www.zdnet.com .
In https://www.zdnet.com/article/heres-how-you-can-still-get-a-free-windows-10-upgrade/ the suggestion is to go to the Download Windows 10 webpage whioch I did. then I clicked the Download too now button. Thereafter I just followed my nose and two hours later my little server was proudly running a licemced version of Windows 10.
So the free upgrade from Windows 7 to Windows 10 is till available!
