Thank you for checking. There are no splitters or amplifiers. Dedicated line straight out to the street. Cox tech pulled a brand new one a few months ago when he bypassed/rewired to remove the cox phone equipment that had been left inline from when we cancelled that years and years ago.
I'm not the only subscriber in the neighborhood experiencing the issues. The DS power was never that high before. I didn't think of checking that when we first started experiencing this about a week ago but had checked within the last couple months. It's been up a little more than two hours since I added the FAM-6 attenuator and zero corrected or uncorrected on any channels since then. (except on the OFDM PLC channel which shows over 99M corrected and zero uncorrected).
I'll check again in the morning.
