Uh... yeah. My problem was finally solved when I pitched a fit and got the cable company to send a whole team of techs to my house. Among the many things that they corrected... I had a pre-fabricated cable going from the wall to a TV in a kid's bedroom that was picking up interference from an unknown source. He scanned my signals just about every way he could think of. He even disconnected the cable feed from my house to analyze the signals that were infiltrating into my coax. He and I narrowed it down to that cable. It was causing problems with the tuning adapter because the interference was in the same frequency band as the up-stream signal from the tuning adapter. The tech made a new cable and the problem went away.jziggity wrote:He did look at the wiring, and immediately complained that my splitter/amp was not provided by them. He also complained that all non-TWC provided coax runs were loose. I do have commercially purchased coax runs that have boots on the ends which are admittedly loose, but just the boot part, not the threaded screw-on part that actually makes the connection - the threaded parts are on tight. I know the entire cable system can be very sensitive, but could it really be the cables that I used (and have already run through walls) are the major culprit?
They also replaced the cable tap up on the pole, cut off the end of the cable that feeds my house because it was chewed by squirrels, and replaced my old 4-way +7dB amplifier with a new 9-way 0dB amplifier... and ran an additional drop to my wiring closet so that my cable modem no longer shares a line with my HD HomeRun Prime tuners and TA's. This allowed me reduce the number of splitters in the closet.
