Re: [Discuss-gnuradio] gr-fosphor : New RTSA-like visualization block for GNURadio using GPU acceleration

Yep, I concur. It is blazingly fast at rendering with the HackRF :)

Can we control any options on the sink? For example frequency scale,
waterfall rate, etc. A callback would be nice too. I'd like to use the
fosphor sink in my gr-kx3 script that I use to control my HF transceiver.

This is very cool. Thanks.
