SKYMAX: @ sidefx
It's a bit weird that you would have a dip in your lower frequencies, usually it's the higher frequencies everyone loses.
Thanks mate; Though looking at some of the other ones in this thread a few seem to dip around carrier 256 (c.f. richms', SamF's and even the one on 17a in the original post)
Ah well, guess I'll see what happens over the next few days.
