i have no idea how they work. i am very sick of using the tracks transponders.

plug it in your receiver and at your track they will assign your name to it when you race with it and then whenever you look at your laps your name will be in there. or when you,re racing. plug and drive.

o ok. i mean like i knew how they worked but i didnt know how u could use ur own arnt they like 100 bucks tho

i know at my track they hand out transponders you have to put on ur car but you cant use amb pt you have to use they ones they hand out because there lap counting software does not pick the signal up. and yes they are like $90- $100 i have one that i cant even use.

AMB is the most widely used.. and yes, they are now $115

Check with your local track and find out what they are using... there are a couple others that are not compatible..

If your track uses the AMB system you can buy a PTX transponder from http://www.team-mrt.com/. I have three now and they are great. I bought two of them not long ago for $136.00 delivered. Half the size of an AMB.

Each personal transponder from AMB has a unique number, this then gets associated to your name. The handouts have a number but it is unually between 1 and 10. The other option is to buy a transponder from MRT. they can either offer them with 10 numbers, 20 numbers or a copy of your AMB transponder number. The 10 and 20 number options may be limited at a big event since they are not unique number, but the same for everyone who buys a 10 or 20 number transponder.

Personally I got a AMB one to get a personally number, then had a few copies made by MRT. MRT was about $60 each, so a lot less than the originall AMB. That way all my cars have the same TX number.

This is ture to a point I have three PTX transponders and they have three unique numbers. If I get any more from them I will just have them clone one of the numbers and then most of my cars will have the same transponder number....OR I might send them them one of my AMB transponders and have that cloned.

Thats because your track either has an older AMB system that is not digital or another lap "timing" system. Has nothing to do with the software.


1-10 house TP's are from the older systems. The digital house TP's have a 7 digit number just like a PT.

I don't think MRT sells 10 nomber PTX's anymore... They all have 21 numbers in them.



The three you have do not have "unique" numbers in them. They all have the same first 20 numbers, but the 21st number comes from a pool of numbers that MRT has... they have already been cloned and other people have them.

Its a great product... and helps the racers out.
