Looking for a used, working AMB 260 transponder. I'd prefer a direct wire, but will consider any working unit.

Thanks - Ryan

I have both $700 for Direct wire, $500 for rechargable

I still don't understand how somebody can't reverse engineer these things

I found one guys. At a little less than the offer above

How would you then register a fake transponder for use?

reidry

This discussion centers on transponders used for car and motorcycle racing. Note that aircraft transponders allow the user to change the squak code and air traffic control then associates that code with your tail number.

The difficulty with a "knockoff" transponder is ensuring the end user has the ability to choose a transponder code that is not in use at that event. This brings up a potential "unintended consequence", if the user chooses a transponder code for which an AMB user has a registered mylaps account, that user will have "ghost" events in which they did not participate.

is it possible to rewire a chargeable transponder to be wired? mine will be dead sometime soon, as its over 10 years old and hundreds of charges. when it goes can it be converted or will i have to perform surgery?

How did you read into my comment that I was referring to an aircraft transponder? Just curious.

reidry

I didn't, but I work in a related industry and thought the difference between the programmable aircraft units and the AMB one number for life units was interesting in and of itself.

Mark: Do a search on ebay. Battery kits are about $55 and should bring you back to life.

You don't have to register the old ones. Sure you can to get info from mylaps (never have). The only person that needs to know what the trasnponder number is is the T&S guy. The only issue would be if you are at an event with somebody that had exactly the same transponder number....would be nice if you could hook it up to a computer and change it if you needed to.

My understanding of the transponder is it just sends out the transponder number. Unsure if it does this constantly, or only when it get excited by the loop. I mean, how difficult is that. All you need to know is the frequency and the block of data that is sent (what it contains and how it is formatted).

A patent on it might explain the why...

Man I remember the good old days when you could get a non subscription transponder for 300-400 used

What a sweet situation that guy (AMB) has created. $500 for $1 of hardware and technology around it built by someone else.

Thanks Rob!! 55 bucks is cheap enough to not do some hack electronic surgery!
has anyone done a convert? (to direct wire connect?)

(sorry to hijak a little here)
