Start sensor problem?

If you can blow into the start sensor nd get a start then should be able to get astart from the gun.

I normally have a small loop set, where the starter can slide this on his finger into thus getting the sensor as close as possible to the gun. In measurable terms, if you can get a start from the far side of track by blowing into the sensor then you should get the same result. Lastly, you may want to try form different distances, and see what results you get. Its possible you may be receiving interference. Also, I notices there is somewhat a small delay when the gun is shot and the time the signal reaches the receiver.

Over the last 4 years I've had times when the radio system worked great, and the next meet at the same site it would miss 10 % of the races. So, Try to have the antenna away from metal like the tripod or the frame of tents, try to have the antenna in line of sight without having people or things between them. One starter that works with me seems to be a radio block, the signals do not go through her body. Try to have a walkie talkie to have the recall starter bring back the race if you don't get a start or have a gun where you are to stop the race, work out with the track ref which they want. Try and keep the transducer as close to the gun as possible, but try not to have the discharge from the gun aimed at the hole in the transducer, One starter use to go through a transducer in 160 races (wired system). He would aim the discharge of his .38 right at the hole from 5 to 10 cm away. The noise was so loud that the transducer would lose it sensitivity. The old wireless transmitters had problems with antenna wire coming lose. carefully open up and see if that has happened. The antenna may have gotten an internal break that affets its range. I started one meet and would have to carefully walk back to 70 meters from the timer and resend the signal.
