They're called Senior Moments. Treasure them while you can still
remember them.

Whether intentional or not, once the transceiver receives/decodes
the RF, it sends it to the powerline (after waiting for a positive
ZC if unit 1 or 9).

If on opposite phases, for units 1 & 9, one will lag the other by
1/2 cycle (1/120s or 8-1/3ms) which guarantees a powerline collision.

I doubt you are able to discern an 8ms difference in the relays
activations. If you can detect a time gap, there are two
possibilities. Either there is a space/time loop (unidirectional, of
course) between the transmitter and one transceiver or one of them
is receiving a weaker RF signal (or has a weaker receiver) and
cannot decode the first copy. The first copy (or copies) will still
affect the gain and threshold so that it might be able to decode a
subsequent copy. Copies are sent at ~108ms intervals. As much as I
like the first scenario, I suspect the second scenario is more
likely in that the second scenario doesn't require opposite phases.

(goes to check to settings and PIC codes)

There's a third explanation!!! Hmmm, color my face red. The module
controlling the powermid in the bedroom is an appliance module. I
just moved the damn very heavy bed to make sure of the PIC version of
the TM751 and miraculously, it morphed into an appliance module
before my eyes! Damn that X-10!!!

I guess my item/location database was wrong. Thanks for not calling
me too big of an idjit. D'oh. The delay I heard was the TM751
receiving the RF and clacking on and then putting B1 on the powerline
via the appliance module. That's a delay that's quite apparent. Oy,
do I feel dumb.
