Pairing RR501 with XPS3

[smokey847]

Do you know of any common noise makers?

Plasma TVs, cell chargers, some CFL bulbs, LED bulbs, newer microwaves and refrigerators, computers, laptop "bricks", some HVAC systems, circuit boards on some washing machines, etc, etc.

Jeez, we have nearly all the things listed.  Any ideas where I should begin?

I would unplug devices and see if things improve. Computers, any type battery charging devices, TVs and electronics.
CFLs can be found as the problems change as lights are turned On and Off.
I believe the links I gave earlier have some tips on finding signal problems.

If you are really serious about finding and fixing signal problems. The JV Engineering XTBM test meter is the best and their XTB-IIR is the best coupler repeater made in my opinion.
