Most phase coupler/repeaters repeat only the second copy so the off phase
will only see one copy.

The receiver has no way to know whether it is seeing the first or second or
Nth copy. It can only look for 1110 followed by a valid code.

I have no idea whether it's possible to hack the Monterey - $300 is a little
too dear for experimenting. It would be better to start from scratch and
design an inexpensive circuit that would output via RS232 or USB. That's
still on my list but I may never get to it.
