It was a warm, sunny day and I was able to roll it outside to check the GPS, transponder, and the COMM radio. The GPS picked up enough of the satellites to give me position information. The transponder displayed pressure altitude from the blind encoder and received radar replies from the Lincoln tower, and I heard both tower and approach control on the COMM.

This is a great milestone and means I can move on to other things.

The first video is just the headset and tower.

The second video shows the transponder reply. Just beneath the ON in the display you’ll see two quick flashes of an R.

The third shows position after picking up enough satellites.
