Re: SDR Console 3 Spectrum background colour

Simon Brown



Been thinking about this. Quite a lot of code needs updating to support alternate backgrounds, for example S-Meter, default Marker colours, RX markers, Peak values, possibly more.


  • I will add support if there’s someone who cannot use a black / very dark grey background.
  • The current scheme is high contrast, this can’t be improved.
  • When printing in a magazine the values in the spectrum scale aren’t really too important, when they are then data is usually exported to a 3rd party program for analysis. Irrespective of colour, the scale font size is so small that it’ll be difficult to read in print format.

Hello again Simon

I would be SO happy to see a simple choice of three options for "background" on the spectrum window:

1)  Present option  -  dark grey
2)  Pure white background or very light grey  with the dB values grid in a darker grey
3) Very light blue background

Obviously some choices of background and spectrum color would clash.
I note some of the colors are very flashy - cool to look at but not so suitable for publication.
I'm looking for something simple with high contast.

Am I remembering correclty that Console V2  did have options for background color on the spectrum?
Maybe I am thinking of a different ap I've used in the past.
But I did submit a few articles to QST over the past ten years which had a better contrast than what I can now get with Console 3   (And SDRuno which is even worse).

with appreciation for all that you do to make these apps look so good and work so well,
