An additional thought. The third cycle is not the thing you would see on a scope looking at the raw signal. The rcvr determines when the signal has risen above 0. That may be 1 to 2 really small cycles. Its from that point its the 3rd crossing. Normally there is a gate out signal thats useful to trigger the scope with. Regards Paul
