Hi all
Last evening about 9pm I noticed numerous Time Warner cable TV service
trucks on my street, flashing lights and all. Line men up on ladders at the
utility poles, all up and down the block. After a while a knock on the door.
The lineman wanted to know if I was a ham and if I was talking at about 6pm or
so.
I said I was and they told me they were experiencing interference problems
and wanted to run some tests. So I transmitted and It was confirmed. My being
on the air shut down a entire node of roadrunner cable internet service. The
lineman said some 200 were affected. nice.
This was on 3.967MC. at 1500 watts. They ran some more tests, disconnecting
my cable TV drop to isolate me from the system. No noticeable change. We found
that at 30 watts they can tell when it is keyed on and off but no one is kicked
off the internet. The tech said It was not back feeding from my house but
maybe the neighbors or the line. On Saturday they plan to return wanting my
cooperation to allow them to drop houses one at a time until they find the
cause. They claim they have been looking for this intermittent problem for
about a month. When they get to the complaining home they find no problem. I
just don't talk that much.
At my home there is no interference, cable TV is clear. My computer sitting
next to the commander runs RTTY with the DSL internet on and stable. I'm glad
I can't afford road runner. They begged me not to transmitt until Saturday. I
find this all very interesting, and can hardly wait until the problem is found.
Anyone have experience with these cable internet nodes ? I don't have much
experience with cable internet interference. Mine was the air conditioner fan
turning on and off, while the garage door open itself up. All cleared up long
ago.

I will post again when I learn more about this.
