Narrative:

I had communication #1 fail and tuned to communication #2. I got no response on communication #2. Suspected radio failure or antenna problem. Turned on landing light. Looked for wind direction and traffic. Windsock was limp, so I took runway 14, that was same as my departure 6 hours earlier. Near touchdown, I saw the katana lifting off about 500 ft ahead of me on runway 31. I moved to the east and katana went to the west. I taxied to tiedown and looked over the alternator belt and tried to move electric flaps. Flaps moved ok. So I tried to start engine and failed. Suspect alternator, regulator, battery or short. All breakers tested 'in.'
