The type of Transponder you need will be specific to each club or circuit. Usually on the club’s Entry Form it will give you an example of the Transponder in use. For travelling championships this could change from venue to venue, or be provided for you, so speak to your club before purchasing anything.
No – you should use the same email address that you use at one club with another. Creating a new account with a different email address can often lead to duplicate drivers being created for each club, causing issues with Memberships and Race Numbers. Please contact your local club if you need to make changes to your account.
You can change your email address by logging in to any club that uses Alpha and clicking the Edit Profile button in the top right of the screen. On your profile next to your current email address is a Change Email button. Enter your new address and your password to confirm the changes. If you are unable to access your email address please contact your club who will be able to reset it for you.
If there is an issue with the results on our results website or your entry information is wrong, you will need to contact the club or circuit in question. We create the software, not the results which are stored on the timing laptop. Any discrepancies you have should be directed to the Club’s competition secretary or Circuit Management. You can usually find these at the bottom of the Club’s login page or website.
The circuit’s timing system and the lap timers are using different methods to calculate lap times. Circuits will use a detection system installed into the circuit that uses radio waves to detect a transponder and estimate a karts time and position over these detection loops. This is then recorded with a timestamp which our software interprets into your lap time. The accuracy of this depends on many factors including the quality of equipment, the installation of detection loops and transponders, and weather.
Lap timers typically use GPS to calculate your relevant position a certain number of times a second. They use this position to calculate the time you were last in that position or through waypoints that you configure. A lap timer set to 10Hz would be accurate to 0.1 of a second. Some older lap timers use a magnetic read valve that is activated is it goes over specific measuring points on the circuit (if installed).
