Default Could somebody please try to doppler this?

Could somebody try to get a doppler reading from this video clip? I know you guys have said turbines don't read great, but we put a new engine on my kingcat and it's got to be pushing 300mph. The fastest (I think) pass is around 1:35 on the video, I have had this jet on radar with the old engine (28lbs of thrust) at 230mph, the new engine is 44lbs of thrust, would love to get an idea of how fast

Thanks in advance!

Dude... I don't know how fast it's going but I'd put it in the redonkulus range.

I'm fairly sure it's passed ludicrous speed and is pretty close to plaid LOL

My recordings were a no go in the Doppler program. Maybe someone else will have better luck as I have trouble with 4 strokes and DF also.

Thanks for trying Mike, I remember you saying you had trouble with turbines in the past, wish we had had a radar gun out there, that thing is cooking!

For doppler to work, it has to be a constant sound so you can read the drop in pitch. This jet has a totally different sound when it is coming at you than when it is going away.
