I think you may be changing directions too quickly (ie turning too soon after passing camera), you need to get like 3-4 seconds coming and 3-4 seconds going as close to camera as possible for best doppler.

What software do you use to take the audio from the video Mr. Don ?

Actually for most general dopplering I do not sample but doppler in real time with Vspectrum. If I have trouble seeing the sounds then I sample with windows sound recorder and save in 8kHz format.

I got 68 mph, is that a 3 blade rotor you are using with stock tailpipe?

How do you get VSpectrum to recognize the sound ... mine just has a bunch of yellow lines.

I guess I am not playing the sound the right way...

Any ideas ?

Need to see a screen shot to see what you are seeing.
