Human Factors
[I] announced entering runway for glider hook up; then called taking off on 30 with glider in tow. Looked for traffic and departed. The glider I was towing was a heavy 2 place with water and we took off and when I was just about to lift off or had just lifted off a Cessna appeared on runway 16; he had landed 34 and was back taxiing; he later said he had landed 16 (?). I called on the radio to him; 'whoa pal; are you gonna stop?' or something similar. Then he continued toward the intersection. I yelled 'stop' on the radio and he continued (obviously no radio or wrong frequency). Anyway I could not stop before him; nor could the glider so I side stepped to the north; and once past him the glider released and landed straight ahead. I continued around and landed on 30. Airport personnel that witnessed the scenario went over to him to ask if he had a radio; he answered yes and said he was on 122.9 and our frequency is 123.00. He also stated he landed 16; which was disputed by all; he had landed 1/2 way down 34. What could I have done differently; I do not know; I looked and obviously did not see him and certainly did not hear him.
PA-25 pilot towing a glider on takeoff maneuvered to avoid opposite direction traffic that had not checked in on the common frequency.
