My original transponder installation in my panel. A Narco 50A. The transponder worked fine when I bought the airplane two years ago, but it was failing and obsolete. It was not worth repairing.

Key Takeaways:
- The author upgraded an obsolete and failing Narco 50A transponder to a new Stratus ESG transponder system in their airplane.
- The installation involved replacing the old rack and encoder with a new, more accurate encoder (25 ft accuracy), and drilling a new hole in the fuselage for a dedicated GPS antenna.
- New antenna cables were carefully routed, and the Stratus 2S unit now integrates with the external GPS antenna, eliminating the need for a sky view.
