No, unfortunately I don't own a scope :\

Tried the original RCHourglass amp and the PSOC behaves the same.

Shortening the loop to 3 x 0,4m, things do get a tiny bit better.
Noticed a "funny" thing. If I poke the transponder with the loop wire to get a good detection, around 90 hits. I can then drive the car over the loop and get 1-2 hits about 8 out of 10 times.

I keep getting this strange feeling that I've missed something obvious... again
