Brief Description:	Worked on radio. Calibrate eletronic fuel sender.
I brought my flightcom headset to the hanger. When set to mono I can hear in the left ear, but nothing when set to sterero. If the jack is inserted to the first detent, I can hear in both ears. My hanger neighbors lightspeed headset did the same. I have a call to Aircraft spruce, who made the harness. I also started to calibrate the Princeton electronic fuel sender probe. I started with 2 gallons at the empty mark. Approximately 30 min of flight when it reads empty and I will finish tomorrow.
