I have a 1975 F model and believe I have a squat switch and a gear safety bypass switch which I think was added after original manufacture. I also have a manifold pressure indicator switch which turns off the gear warnings over 13" pressure. I don't believe I have an airspeed activated switch. Here is the problem: 2 days ago, at a visiting airport, after being tied down in a heavy cross wind all day, I started up and after idling a while, the gear unsafe light and audible alarm went off. It continued until I pressed the bypass switch. I then taxied and it went off again and I did the same thing and it went off again. After figuring it was just a problem with the warning system and not the gear, I took off. Looking back at it, it was probably a bad decision, not knowing what was really wrong. At the time, I thought the turbulence on the ground might have temporarily disturbed something as well as some moderate turbulence on the way there. The gear retracted normally, I flew for 2 hours, no warning lights, sounds and landed at my home airport with no malfunctions. I then taxied back to my hangar and no warnings occurred. I plan on having it looked at ASAP. I am wondering if it is a gear down position (over center) sensor switch malfunction. I should of let the warning continue and see if it went off during the run up when the manifold pressure was raised. I was wondering if anyone knew what could of caused it. Thanks in advance. Larry
