I am moving more quickly to decoding the Specific Area Message Encoding bursts and the grc is now available on my github page and may be cloned as usual from this instruction.
git clone https://github.com/n4hy/NOAA-WR-All-SAME.git
You will need to build uhd, gnuradio, gr-osmosdr, gr-burst, and gr-eventstream to run all of the code and there might be other additions. I hope I do not have to write new code and go through the hassle of getting it included.
The display and controls are getting more complex. I am loading it up with diagnostic information right now.
