Doesn't the PFB channelizer down-sample as well? So your output sample

UHD USRP sink?

That's what I'm trying to figure out. A 4x interpolator doesn't seem to help, though. I'm not sure if the "oversample" parameter in the channelizer might act as an interpolator, or if that provides some other function.


Also, looking at your flow-graph, all of the channels are effectively at baseband, so if you have two or more channels come up at the same
  time, they'll collide--was that the intent?
