Plans: 1. Continue painting the engine compartment panels. Status: The top cover is complete and the lower section has had two color coats applied. 2. Move the transponder antenna and increase the ground plane's size. Status: Complete. After some thought I decided that I wanted a large ground plane for the antenna. I also decided to move the antenna further away from the stirrup. I removed the small plane and replaced it with a 2 foot square sheet of aluminum. 3. Complete the transponder harness installation. Status: 95% complete. I hooked up the ends of the transponder cable and powered the system on. So far so good. No apparent smoke and some information displayed. I did not get a opportunity yet to go outside and check the operation. Some system settings are yet to occur. Hopefully there won’t be any operation issues. This is a good sign. There is one issue that will need some attention. I forgot to provide space for the headset connectors when I added the circuit breaker panel to the harness. I will need to remake the panel and move it slightly. I will also need to make an extension to the headset cabling.
