I can assure you I didn't do it as I was not even at my desk for the last two days. Anyway, just to say that I don't know why this message was sent around again, but please ignore it. I already received help from several people concerning the spectral rotation issue.

We are looking for something that will simply take a signal and flip it around a given frequency. There are probably several ways to do this, but if anyone has a ready-made script that would save us a bit of time. Thanking you in advance Robert
