Carmine, that brings up another point -- why
doesn't X10 offer a really simple/cheap
signal meter?  I hacked into a lamp module
and extracted the signal after the tuned
circuit and made my own monitor (for
nothing).  Again, this could be a lot
simpler and cheaper than a lamp module and
would be very useful.

Yes, I know X10 is old technology but so am
I and my wife hasn't wanted to replace me
yet...  This X10 is a lot of fun to play
with and you can learn a lot from hacking
it.  And its cheap cheap cheap!!!  Like this
week they're offering motion detectors four
for the price of one!

As for the V572, when you've got lots of
sensitivity, you can always cut it back
(lower the antenna for instance).  I never
could get a TM751 to work in the next room,
let alone from a motion detector on my
driveway (not to mention the eternal hang-up
problem).  You can also tell it to ignore
only the code you want so extraneous signals
are easily ignored.

By the way, I have found the CM15a to have a
much stronger output signal on the line;  it
has actually reduced the problems I had with
the CM11a.  Now if they would just get the
bugs out of the macros...

Carmine,

The original purpose of having so many X10
housecodes was to allow neighbors to
peacefully coexist.

People tend to forget because the WGL 572
works great out of the box, but it is
programmable to tranceive your choice of
housecodes, units 1-8, 9-16, or all of the
above.

All you need to do is use the original
Activehome software with a CM11a to monitor
signals for a few days, then map your
devices and your 572 to ignore housecodes in
use by the neighbor.

David L:  You mentioned building your our
filters and line meter.  Is there any way
you could share this information with the
rest of us?

FormerAHP, I have a well-stocked junk box
and if I showed you the parts I used you
wouldn't be able to buy them anywhere.  You
can cannibalize things like old printers or
computer power supplies and you will often
find a very nice toroidal filter on the
incoming line; the only problem with these
is their low current rating and lack of a
case but they work well for light loads.

But the nicest way to make a filter (for
instance to keep your UPS and computer from
absorbing X10 signals) is to cannibalize a
lamp module.  This gives you a nice case
with the plug and outlet (so it is safe) and
you use the noise inductor (choke) that
comes with it, along with a capacitor.  This
should handle a 500w load without getting
too hot.  This choke (apparently) is rated
at 110uh.  There is info on the web with
some very elaborate filters and also very
simple ones; I have found the simple ones to
work well enough for me.  I do not have the
links handy but will see if I can find them.

FormerAHP, here are a few links re do-it-yourself noise filters.  There is a wealth of other info on the web.

If I find info on the Lamp Module hack, I’ll post it.  It's extremely simple: one choke, one capacitor.  It's just a broad low-pass filter but seems to work, and makes good use of defective lamp modules.

David L has a great junk box and some well
thought out sources for coils and torids. I
build my own filters also and have great
success with "in line" filters from the
surpluse houses.
http://www.meci.com/Catalog/Category/afe1542d
-1295-4764-82d0-24135bc39765 is an example.
I have used several of the 560-0104 by
either making extension cords or outlet
stips with the filter in series and mounted
in an insulated box. The "line filters" stop
the noise from switching power supplies (and
stop X10 signals with equal efficiency).
