Karl,

It's not a problem with the Y-Scale. The problem is with the code the
displays the history information. I'm using a technique that draws the data
faster on the screen by averaging the data. This produces a trace that's
just a little different then the trace that displays the real-time data as
it comes in. I'm not sure I can do anything about this problem unless I
rewrite how WinSDR draws historical data on the screen. I'll put it on the
todo list....
