Hmmm. What sweep problem did they correct, exactly?

Looking good... I'll give it a try this weekend. Is anybody sure what was the sweep bug they fixed?

I don't know what they fixed about the sweep. The log sweep for wide ranges in a short timespan (10kHz to 1MHz in 1s for example) still makes no sense at all.

Yeah. There's a bug that happens when you have a very wide logarithmic frequency span, where the low frequency changes basically look like big steps that get smaller as frequency increases. It probably happens because they make the frequency steps linearly and then apply the log, instead of spacing the frequency steps logarithmically. I haven't thought it enough, though. I'll take a screenshot so that you can see.
