Is there a way to add some type of interpolation or smoothing function to the slower scope (due to 115k serial port limitation) with radios like the 7300?
That is an interesting idea. I think what you would get is “fuzzy smear” between the data points. I’ve sort of tried this by turning on anti-aliasing and zooming in.
The data simply aren’t there in-between, so the best guess is from a linear function between the two points.
One thing we are looking at is doing an audio waterfall (similar to fldigi), and this would of course move significantly faster.
