Chris,
I have successfully done coarse acquisition using the correlator developed

A plot of the 'acquisition' is here

Update: I'm not exactly sure what I did to fix but disabling the ESD (sound
mixer?) seems to have fixed it. All the GRC examples now run except that
they have choppy audio. This appears to be a vmware related issue because it
happens in command line too.

Hi all,
I know that there will be another burst of OFDM development work in the
coming weeks so just wanted to add some input that might be of interest to
all.

Hi guys,
I am interested in being able to generate ATSC/8VSB modulation and/or
playback a sampled ATSC/8VSB signal.
The modulation calculation does not need to be real time and can be
calculated off-line.
The playback of the pre-calculated modulation would be real-time and
loop the short bur

Hi everyone!
I'm trying to represent at the same time two different signals with
two scopes, so I can see if the PLL is following the signal he is
getting from the input port. However, the scopes don't work at the
same time, it's like when one of them is working, the other gets
freezed and so on!
