### m17_rx.grc
This receiver testing example relies on ``../M17_Implementations/SP5WWP/m17-coder/m17-coder-sym``
to broadcast a signal. Following this unit testing example, run this flowchart along with

mkfifo /tmp/fifo1
mkfifo /tmp/fifo2
python3 ../M17_Implementations/SP5WWP/grc/m17_streamer.py
../M17_Implementations/SP5WWP/m17-coder/m17-coder-sym < /tmp/fifo1 > /tmp/fifo2 &

It would be wise to execute from a terminal rather than the GNU Radio Companion graphical interface
to avoid flooding the console.
