I just merged and pushed Sebastian's quick fix for the issue.

Sorry to dig up an old thread, but does anyone know of anyone who's
implemented a polyphase filter bank on a USRP FPGA?

Yeah, I'll do the same; enter a variable I haven't created yet. I'm afraid of putting pop-up boxes like this, though. You'll still see the red text in the block and the GRC error button will be enabled to help you track things down, so there will be an indication that you've done something
Any idea on this? Should I post the images somewhere else?

I'm not sure how the GSOC thing works, but if there is anything I can do
to help make this project happen, let me know!
This very idea has been on my "some day" shelf for far to long...

Count me in, but it may just be the two of us as usual. :-)

To me it looks like it's taking some time to acquire, which is normal for a
closed-loop timing recovery algorithm. This is one reason packets have
preambles. If you need it to lock faster and don't mind some self-noise,
and if the SNR is high enough, you can turn up the gain of the M&M block
(chang
That could explain it. However most of the time it locks just fine even for
the preamble with the same block parameters. I'm not sure what causes this
variability and if I have control over it of not.
Might be related to when the MM clock recovery starts sampling the signal.
Sometimes it's lucky a
That's very likely it. It's effectively starting with a random guess as to
the bit timing, and it locks exponentially faster the closer it is to
correct. So for a worst-case guess, it'll take significantly longer to lock.

Not a problem - It was under a VM, so that is probably what was causing it.
I ran it at home on bare metal with a HackRF and didn't have any issues.

Hi Ken,
welcome to the community!
I'll go ahead and answer in-line, since this seems to make sense here:

You can count me in too, even if I just sit back and listen, and learn.
I am at least good for a second round.

As most of you likely have seen, I've been working on a flowhraph for quite
some time. Using gr-drm and an external FM processor, I have made a sort of
open alternative to HD Radio...because fun.
Anyway, the DRM signals are sampled at 48khz and the FM portion at 192. The
remainder of the graph is
