Hello all recently got Verizon Fios installed and now i'm getting terrible hash and noise from it,HF is horrible 75m 80m 160m 28m etc, was on the phone with them (verizon phone tech) and was like talking to myself no knowledge whatsoever. The day Verizon tech hooked up everything as should be a unit outside the house, a backup unit (ups) inside the house just under the window inside and 5 feet away from the outside unit, when I run cat 5 from the modem/router to my comp i get tremendous hash when I remove the cat 5 the noise is totally gone I do not have phone service just internet and TV... I did some extensive testing changing cat 5 cables ferite chokes 31mix 43mix to no avail!! BUT here is the real kicker when i disconnect power from the Actiontec MI424WR router/modem (just cat 5 from router/modem to computer) and put the coax center pin in the modem first all still quiet on my Ham Radio RX, but when the ground is screwed on my RX is a nightmare??? This blew me away because there is no power being applied to the router so how and what is being transfered to cause the interference grounding?. I checked the outside ground for the unit outside and it is fine...This sounds like a ground issue with the outside unit? I don't know, naturally if i turn off the computer i get no interference at all...all i can say is bizarre! Had Verizon tech come out to the house changed all compression fittings replaced 2 splitters, tested another Router replace cat 5 from modem to comp....NADDA same prob..sounds like 60hz type buzz...doing some research the battery back up (UPS) has an internal charger,charging the back up batt could be the batt charger leaking RF in the house and grounds? ...Has anyone had this problem the tech is stumped and has no idea..
