Thanks, Tom. So it appears that you use a firdes.lowpass type function in the taps setting.

So your output sample rates from the channelizer will be mis-matched to theHowever, 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)?John
