I had a friend from University visiting. He's an airline pilot and was very interested in my RV build. I brought the the avionics rig outside and fired it up. I also hung the GTN and GTX antennas on the wooden fence to get a GPS lock and also test the air to air ADSB. As soon as I got a lock the traffic started to show up. I picked up traffic from all altitudes and to top it off the noise interference on the intercom was now gone. All in all a successful Avionics demo and also one interference snag out of the way.
