I'm just north of Philly in Lower Buck Co. We had a cable outage overnight between 9/17 and 9/18. I noticed yesterday that Comcast has shifted all the channels that were between 700 and 750 MHz down below 500 mHz except for the Music Choice stuff that remains at 753 MHz. They even shifted several of the 500 MHz channels lower in the bands.
Would this be due to the 700MHz+ interference issues that we've seen in my area ... probably due to cell interference. Or, would they be looking to expand the internet bandwidth which is currently running from 650-700 MHz.
My neighbors were already complaining about pixelation and drop-out on certain channels. Sure enough I checked my cable boxes and there seems to be a large downstream power drop (around 5 db) and SNR drop centered around 333 MHz. It's not affecting my service yet, but I could see how folks with already weak signals could run into problems with those channels.
What would be interfering around 333 MHz?
