mackie1604,
Adding TM751’s or RR501’s
WILL NOT solve phase problems !
Note: If you should ever need one of these transceivers, avoid the TM751 it could cause you problems; For instance if it and and another is on the same house code and receive the same signal they will both send the signal at the same time. Whereas the RR501 is polite and one should wait for the other to finish sending. Obviously, the RR501 is the better transceiver.
Installing a phase coupler is inexpensive and in my opinion a must.Some people with very large homes have found a need for a Coupler/Repeater.
In my case, my home is 2000 sq ft, and my garage is 100+ feet away. I just use a coupler and everything works just fine.
One of my favorite places for X10 equipment is AutomatedOutlet found here:
https://www.automatedoutlet.com/home.phpYou can get a 4816 SignaLinc Phase Coupler for $19.99
and should you want a RR501, you can also get it here for: $15.99
Also in my opinion: You should have
filters on EVERYTHING that may cause power line noise. Things like; Surge suppressors, TVs, UPSs, Computers, Power Adapters, Fluorescent lights, Heater fans, etc., etc,. etc...
Knowing that some of us can’t afford test equipment. AutomatedOutlet provides a FREE meter for testing.
Elk Signal & Noise test meter - FREE test $85.64 Order and pay for it (This is to ensure that you do indeed send it back.). Then when you’re done, return it and you’ll get your money back: Part Number: Elk-ESM1-test
AND ! YES, definately map out your circuits. Breaker boxes are notoriously not labeled or labeled incorrectly. So, get someone to help you and check exactly where each circuit goes.
Correction From dave w: "Every panel I have ever seen, BOTH phases were present on BOTH sides of the panel.
From top to bottom of the panel, each breaker is on the opposite phase as the one below it."
Thank you dave w.
Hope this helps you.
