Not sure if this is of use to anyone, but I'm posting to find out...

Attached is 4 oscilloscope runs from 3 of my transponders, 2 rc4 one hybrid. the fourth run is two transponders on at the same time.

The files are in .csv format, you can graph them etc

I did these to see if I could end up with my transponder numbers from each capture based on all the information that has been shared on these forums so far.

hopefully the captures are long enough.

I own an rc4 decoder box as well, so I should be able to test some of these other transponders for compatibility.

I'm also interested in building something simpler than a fully fledged decoder.. Just something that decodes the transponder number and passes it along over usb. I was toying with the idea of having a plastic car stand or something, put your car down on it and my free software will show you your laps etc
