Actually, DVB-T SFN doesn't really require that. It is claimed that some 
transmitters do require it, but I still want hard evidence for that.

I keep hearing strange interpretations of what DVB-T SFN really 
requires. The spec leaves room for improvement.

PRS10A     PRS10B
PPSOUT --> PPSIN
PPSIN  <-- PPSOUT

I believe he meant.

I also believe he used a separate source for the later experiment.
