[RFI] What Possibly Is This RFI??

[WW3S]

dont be too sure its not in your house ( see Stephanies #1).......I had 
a similar problem a few years back, killed the power to my house at the 
disconnect right at the meter.....the noise continued...ahh ha, not in 
my place, right?!?!?Wrong, long story short it was my cable modem, we 
have voip phone service, and the cable company is required to have a 
battery backup in the  modem so we can have phone if the power goes 
out....cable company came, swapped for a newer modem as the model I had 
was loooooong discontinued, and that noise source went away....now only 
99 more to go.....
