Hi Steve, Thanks for the suggestion…do you think there’s a way to attach a number to the visual representation that appears under “cumulative”? Alternatively, can it be broken down into individual numbers for each of the 50 hz signals that appear across the passband?
Actually, I’ve been using cumulative, and I think that’s what got me thinking about alternate data mining techniques. If one considers two parallel grid cells, one might be pretty dim while the other might be quite bright. At some place in the source code, the dim cell should be translating some number x into a certain level of pixel activation, while the bright cell is translating some number y into more pixel activation. And y should be > x…I think. I’d like to find numbers x and y (and all the other numbers output in a given time unit. In my previous life, I did a lot of spectral analysis of organic compounds, and we used this type of integration to great use. Every time I look at the waterfall and read that part of WSJT-X includes Fourier Transform, I start thinking there’s got to be some overlap that could be useful. But maybe WSJT-X isn’t programmed that way? I really appreciate the feedback…it keeps me thinking. Thanks!

Hi Joe, It sounds to me as if the Cumulative spectrum plot that can be displayed underneath the waterfall is exactly what you have described. The Cumulative spectrum is the sum of all of the short-term spectra that make up the waterfall display. The sum is reset to zero at the beginning of each receive interval. Make sure that the “Cumulative” option is selected from the dropdown menu at the bottom of the waterfall window (just to the right of the color palette selection). You can make the Cumulative spectrum occupy a larger fraction of the window using the up-down arrows next to the box that is labeled “Spec NN%”, where NN will be percentage of the vertical window space that should be used for the Cumulative spectrum.

At some point during an FT8 decode, I’m assuming that there’s a number or library of numbers is generated that is then translated into a visual representation – the waterfall spectrum. Is it possible to tap into the software and download those numbers into Excel or similar? It would be interesting, for example, to integrate the value of each 15 second x 50 Hz block that makes up the waterfall grid. Is this possible ? Has someone already done it? Incompatible with the way WSJT-X works?
