Signal Intrusion Frequency not in Database

Choke the snot out of it. Coil all your available coax into a neat loop as tight and overlapped as you can. Snap on some ferrite chokes and take some steel wool and swirl it around it close to the drop and hold it on by wrapping aluminum foil around it. I had to do that when we lived about 200ft from a tower on an adjacent building.

I am not sure putting a choke on a Coax carrying the signal I am trying to block is workable. But it would be nice if I knew for sure whether the ingress was coming through the cable or directly into the Modem...

@n5ims I am just realizing what you were saying in your post. And they are 45 MHz below the listed frequencies for the trunk. I just have to figure out how to put those in a Favorites list which doesn't disrupt the normal scanning process.

The utilities are underground where I live and no visible signs of damage on the part above ground. But the cable box has been disturbed which is one thing I was going to try to get TWC to check....

Thanks for the responses.

I know the choking the coax sounds counterintuitive, but I was told to try it by my buddy who had 20 some years working as a state police radio tech. It worked for me. When I had moved to that building everyone was complaining about terribly slow Internet. When I figured out the problem and choked it mine was very fast and I could download files without errors.

If the ingress is coming through the coax, then it is the same as the normal frequency. That being the case, it would seem to make it impossible to separate the ingress from the actual traffic. At those frequencies, chokes may have quite an effect. But I will check.

Maybe TWC will know where the ingress may actually be happening... when I get around to calling them. They may even tell me, if the transmission had a data component, it might be messing with the QAM in the modem..

Thanks..

The last update it appears is something has changed and I am not getting the ingress as frequently as before. Last Monday I heard the Public Safety folks were reprogramming their radios and I have not gotten a spike at the specific frequencies since. Hopefully any future incidents will not be a problem.

Thanks to all who responded, hopefully the problem has been resolved. I posted on the DSL Reports forum in the TWC direct help section, but got no responses. Maybe they knew a change was in the works regarding the local frequency use.

It's common to not receive responses. Unfortunately, a response is often taken as an admission that there was a problem, something that many cable TV companies do not want to admit. At least your report allowed one of their inspection teams to pick your area for their "random search for leakage", where they probably discovered the leakage and fixed it "as part of their ongoing troubleshooting process".

I suppose time will tell. As soon as I posted about having no problems, there was a major auto accident on the freeway and all the trucks and ambulances were mobilized... Got a spike/s which caused 4500 Uncorrectables. I am hoping those situations will be few and far between...

Thanks.
