Hi All,
First, I hope this thread isn't viewed adversely by the moderator. I think
it's educational, at a minimum. Of course, I have a vested interest in the
topic right now, but sooner or later, just about every ham will probably
face this issue--rightly or wrongly!
I loved the old Jimmy Hatlo cartoon that "Missouri Guy" posted! Hatlo's
cartoons were a mainstay years back, and I sure miss them.
I very much tend to agree with both Don Wilhelm's response and with Phil
Kane's comments as well. I tend to think it isn't too much wrong to try
simple speaker line filters, which often do solve an issue, but as Phil
points out, today's electronics are much different than what we had in the
past, and it is easy to do exactly the wrong thing! For example, I think
the old "stand by" trick of using bypass caps, which used to work very often
in old stuff, isn't a good idea with today's equipment. Apparently
transistorized equipment, like audio amps, won't necessarily be happy with
such a "fix" the way older tube type gear would. I wouldn't try that!
In any event, I don't want to even attempt to go inside someone else's
equipment. I DO want to appear genuinely concerned and intent on trying to
resolve the issue!
Often the problem, is convincing the "affected party" that it really is a
defect in their equipment, or installation thereof, and not yours. Of
course, you need to be pretty darned sure that is the case! That was my
situation from the outset. All my neighbor wanted to focus on was how much
money he had spent on his "system", equating money spent to a lessened
responsibility. It's very esoteric for most people when you start talking
about bad ground connections on their end, and anomalies like speaker wire
runs acting as rectifiers of RF. They don't think they have done anything
wrong, and they are almost right, except for the laws of physics. In any
event, they tend to view it as an infringement on their rights, and don't
feel any concern that we also have the right to operate a properly
functioning station.
I very much appreciate the responses on this issue. Apparently internet
issues are not that rare, but I was assuming (wrongly I guess) that the vast
disparity between my operating frequency and that used by internet devices
would make this less probable. You learn something everyday! When you
think about it, though, unwanted RF comes from all sorts of
devices--florescent lights, dimmer switches, etc. So there doesn't always
seem to be a harmonic relationship.
Hopefully I will find a good answer to all of this.
