The short duration of the meter's data transmission causing interference  
isn't my main complaint.  I have three UPS power units that senses the  
data noise when the meter transmits causing them to alarm and switch to  
protected power.  At a rate of about 4 switching cycles per day I  wonder 
how long the relays will last.  Also I begin having problems  with 
several X-10 switches randomly operating on or off just after the  
utility meter was installed.  The X-10 units operate at 120  kHz.

Hi Dex,
If the data noise is tripping your UPS units do you think a good
heavy-duty AC line filter in front of the UPS units might stop them
from tripping on the noise?
 
I have experienced the utility meter data noise here and it sounds  like
a sharp squarewave signal with lots of harmonics but it doesn't bother  the
UPS units on my computer and monitor. Luckily it is short duration  here.
