Installed the VHF and transponder antennas. Checked the radio and was picking up ground traffic from the airport located about 0.5 miles away. The aircraft is in my basement level garage so it seems the antenna is doing pretty well.
Installed a master power indicator light. If the master switch is left on by mistake, the master solenoid will drain the battery.
Mounted the Trutrak altitude control box.
Continued with basic instument power and ground wiring.
