I will swap the outlet tomorrow.  My fluorescent kitchen fixture must be noisy because I noticed when it was on, the living room lamp and socket rocket on porch won't Turin on. As soon as I flip the switch they light up when the on command is sent.

Well, it isn't the outlet.  My cpap machine was plugged into outlet and that must make a lot of noise. When I removed it, that lamp started to work.  I miust need some kind of filter for it.
What do I need to block the noise from Cpap machine?

Thanks.

Oh we missed the question "is anything else in the outlet". 

Look at the problem devices label and see how much power it uses.
Then you can find a filter that is rated for the load.
An XPPF is fine for small loads but pushing it to its 5 amp limit may result in smelling hot.
The Smarthome 1626-10 FilterLinc is rated at up to 10 amps and has an unfiltered outlet on its front cover for another item. I have my UPS on a FilterLinc. The UPS is in the filtered outlet and my Insteon PLM is in the unfiltered outlet.

Looks like 4.16a?

We are interested in the 100-240 volt current. 1.2 Amps so I would say a XPPF would work fine. A 10 amp FilterLinc would also work if it  was easier to find.
The 100-240 Volts is also a clue to it being a switching type power supply and probably has a nice big AC capacitor across its line input. Killing most of the X10 signals. Probably just marginal enough that the CFL when On was enough to stop it going back Off.

Just ordered the xppf. Thanks again for all your help.  Looks like I am about there now
