Sorry.  I was unclear.  A while back I looked at a lot of screen shots done
by Dave H. and others that indicated some unusual characteristics for the
CM11A when compared to a TW523 or a Maxicontroller.

AFAIK (and that ain't much!) the CM11A, besides having lower output voltage
than most controllers, also suffers from a peculiar output voltage decay
during the signal transmission itself.  I would assume since you're able to
boost the signal to a uniform output level despite varying input voltages
that the XTB X-10 signal will not contain the original transmitter's
waveform flaws.  I just wanted to be sure a CM11A plugged into the XTB
device would NOT show the same voltage drop during its output burst.

I'm sorry if I am being a pest about the CM11A but I think your device will
have appeal to those who like that controller but do not like repeaters.  If
you don't own a CM11A, I'd be happy to loan you one for testing.

It's probably better that you discover any unusual device interactions
before anyone else does!  IIRC, (but probably not) the CM11A very
occasionally self-immolates in the presence of certain sorts of dimmers, or
at least I vaguely remember reading reports of serious CM11A overheats for
one reason or another a few years ago.

Great job, BTW.  Why didn't someone do this 20 years ago?  Were the
components or the brainpower not available back then?
