Hi everyone,

I updated the ofdm_benchmark_tx.py script to use UHD and I'm running it on
my E100. If I run it at a high enough sample rate, I get a lot of "S"
characters printed to the screen. Some googling shows that this means
there's packet loss within a burst. What causes this? Is there any way to
avoid it?

What is the exact sample rate? Can you post the updated flowgraph?

Have you tried using the NEON optimized fftw mentioned earlier?
