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.
