[Elecraft] OT--RFI Issue

[Dyarnes]

Hi All,

I am in need of some informed counseling.  Hopefully I won't start a thread 
of "war stories".

Some time back, my neighbor complained that I was getting into his TV 
system.  He has Dish Network, by the way, which is the same thing I have. 
Anyway, I immediately tried to be responsive, went to his house to hear the 
problem for myself, with the aide of another local op who operated my rig 
while I listened.  I was getting into his system all right, but it was an 
anomoly.  I don't have any problem with my own systems here.  Anyway, I 
tried a few toroidal filters, but it didn't seem to help.  Fortunately, I 
got some assistance from the local ARRL RFI committee, and it was determined 
that it was his sub-woofer leads that were the culprit, and I had not 
filtered that particular lead previously.  He has a serious "rats nest" 
wiring system running all through his house.  Anyway, A filter seemed to 
solve the issue.

Fast forward to the present--now I'm told he thinks I am getting into his 
phone system and his internet!  I can believe the phone thing--that's not 
uncommon, but also not necessarily indicative of a dirty signal.  On the 
other hand,  I've never heard of a problem with someone's internet 
connection.  We both use the same internet system also--Cox Cable internet, 
and I don't have any problem whatsoever here at my own house.  He is not far 
away, but obviously farther away than my own systems!

I suspect he may be a bit paranoid, and is assuming "any problem" is being 
caused by me.  However, I want to be proactive!  I do, however, want to try 
and be logical about the whole thing.  Intuitively, I assume that if I was 
transmitting a "dirty" signal, it would probably affect my phone system 
(also wireless like he has, but probably a different brand) and internet 
service.  Also, I have now added a low pass filter, but haven't checked to 
see if that made any difference, but I will.  For one thing, I'm going to 
try and talk to the guy "on the phone" to see If I can hear anything when I 
key up.  I've also been reviewing my connections.  In any event, I don't 
want to make the mistake of assuming that, just because I don't have a 
problem with my systems, it must be faulty equipment at his end--or 
something entirely unassociated with my operating.

So, any thoughts or ideas from the group?
