Matt,
I have not and I hope it was a Basic RX board not a TX.

Alfred reply is exactly why I would like to change the sample rate. I am
operating at low frequency and would like to be able to look at the signal
with a different resolution in the frequency domain (time span = 1/sampling
rate, require ring more points in FFT to get resolution). In my career I

Here is A way to accomplish your goal:
You need to have your final sample rate be N samples per second. I will
assume you want (-N/2,N/2) complex frequency.
Choose a decimation ratio in the FPGA such that the Nyquist for the
decimated frequency is LARGER than or equal to N/2. Let this

Will look at your reply n4hy.

It's all in CVS now. Expect some changes over the

Yes.

fftsink and scopesink were just refactored to use messages and message

our dependency on pipes, but more importantly, the C++ side will now
