Not until you have verified your suspicion about the source of your 
noise. At this point, you're only guessing. Study these two links and 
use the techniques outlined to track down the source(s) of your noise. 
At this point, all you know for certain is that it is some form of 
electronically-generated noise. Could be one or more switch-mode power 
supplies or a variable-speed motor controller located in your home or 
the home(s) of your neighbor(s).

Also, study the SDR waterfall technique that NK7Z describes on his website.
