Thanks, Tom. So it appears that you use a firdes.lowpass type function in the taps setting. I've done that and I now get somewhat more sane results on the output FFT.

However, I'm still seeing massive underruns when I assume the same sample rate as the input. Is there a decimation going on (i.e., output_rate = input_rate/num_channels or something like that)?

Doesn't the PFB channelizer down-sample as well? So your output sample rates from the channelizer will be mis-matched to the
  UHD USRP sink?
