This is very true, my X10 phase bridge is not amplified. So

       ESM1

+-----------------------------------+
| O [] [] [] [] [] [] [] [] [] [] O |

Command sent M1MON (sent one at a time not repeated as rapidly as
possible).

Insteon PLC (sending Insteon)

What I see in both the garage (GA) and the computer room (CR) is a
similar spike pattern on the ESM1. At first it seems to pulse between
1v & 1 bar less. Then towards the finish of the command it moves to 1v
to plus 1 bar (see artwork above).

Insteon PLC (sending X10)

CR = 1v (exact)
GA = .1v

CM11A

CR = 1 bar less than 2.5v
GA = 0 (not seen)

TW523 (Ocelot)

CR = 1 bar less than 2.5v
GA = 0 (not seen)

CM15A

CR = 1 bar less than 2.5v
GA = .1v

Cool! Wish I could get a new chip to support both X10 and Insteon.
It's probably doable but I'm a little tight on time. I have a feeling
that many of the fundamentals of X10 PLC will work and x10 problems
will fail in a similar way with Insteon.

Yeah, yeah, I know so why am I posting here, it's a bit of a
distraction. :-)
