Well I couldn't take it anymore. Continuous drops, kids trying to do online school, can't watch anything without regular interruptions. I went out in the PHX heat and traced the cable back to the box. Found a cut in the outer insulation where it had been pinched at the box and corrosion had set in. I replaced the cable and lo and behold all is well.... no loss of synch, less than 50 uncorrectables on all channels over the past 24 hours, - no loss of internet. Why the tech didn't see this I don't know but I'm happy it works again - cancelled the tech that was coming tomorrow...... Wish everyone else the same luck....
