[RFI] RFI from telephone Equipment

[Paul]

For the past six months I've been putting up with S9 noise on 17 & 15 
meters.  On the 7800 scope it's just solid green, no pattern in it.  
Doesn't look like it's going to fix itself so took portable SW receiver 
out and found the source - where the underground phone lines come up to 
a terminal box where the lines to the houses connect, there is a good 
signal, loud with the receiver antenna collapsed.

An Embarq tech was here today cleaning the batteries in the remote 
switch (and fiber to wire interface) - with the doors open there are 
several areas in the switch that are really noisy, but not too bad when 
the doors are closed.

I'm guessing that noise is being coupled to the underground cable - any 
ideas of what to tell them to do to fix this?  Maybe a bad ground, or 
put toroids on the cables?

Thanks
