My Comcast cable line coming in off the street is picking up FM radio stations very clearly. I live in an old home in the city of Pittsburgh, so there are several things here I think "could" be happening. Let me run down my setup.
Cable line from street-->APC UPS-->three way cable splitter-->
split 1) cable modem
split 2) cable card tuner
split 3) qam/atsc/fm tuner
I noticed a tiny spark and received a very small shock when I connected the line from the UPS to the splitter. The UPS is plugged (temporarily) into a two prong outlet with an adapter until I can replace the outlet when I'm on vacation next week. I'd like to test tonight if the FM still comes through without the UPS in the chain (I think I tried it and it did but I want to confirm).
I actually really like the fact I am getting the FM stations because it allows me to get both QAM stations and FM radio.
There are problems though. A few cable card channels are not coming in at all (or do very sporadically) and many of the clear qam ones are pixelated messes.
I am under the belief that QAM frequencies overlap to some extent with FM ones. Could the fact that the FM transmissions are getting into the cable line causing the problems with some channels? What is the more likely culprit - the FM getting in through the cable or though the electrical wiring?
