In this case we tested in the LAB with shared reference and PPS. GPSDO

Hey list,
For those who were not at the GR Conference 2012: I presented some work
demonstrating a simple ARQ MAC over TDMA; using GNU Radio and USRPs in
GRC. Its very cool work, I encourage anyone to take a peek at the
slides, and checkout the repo and run the examples.
The MAC layer work is actu
