Narrative:

After being turned loose from ATC; I; aircraft X; entered right downwind for [runway] 20. I announced my presence and my intention to land on 20. I heard aircraft Y was also right downwind for 20. I called him to try and see where he was in relation to the field and did not get a response. I called aircraft Z on the end of 20 and told him he had time to get off before I turned base. I called to aircraft Y again and did not hear a response. I announced my turn for right base to 20. Aircraft Z on the ground announced that aircraft Y had also called for right base for 20. My wife screamed and looked out of my left window and there was aircraft Y. He turned left and I continued my descent and landed.
