That's actually not surprising. The buffer is established when the

to run. Increasing the size of the filter will not increase the size
of the buffer. We'll have to figure out how we want the solution to

In one sense, this is a low priority because we are moving away from
using the wx sinks in favor of the qt sinks. Still, for now, most of

Orin,
Just curious what USB 3.0 chipset and OS you are using, and if you can go
over 50 Msps? I am able to get 45 Msps UHD Benchmark with the VLI VL80x,

I have a relatively high level question regarding gnuradio and

I'll try to see if this makes a difference. The minimum sampling rate I
