[Linrad] Re: RX overrun error



Joe,

I will try to change fft2 to MMX and see if I can get RX levels close to 0.

Well, it is certainly *a* problem.  Hard to say, yet,
whether it's *the* problem.

I suspect it means that you have not chosen a fixed-point
FFT for the second FFT.  Off the top of my head, I forget
the version numbers that Leif uses here; but whatever
version you are now using -- I think probably a
floating-point one -- change to another.

When I'm home again I will check the FFT versions I'm
actually using.
