Radio intereference on phone

Radio intereference on phone

We've suddenly started hearing a radio station in the background on both incoming and outgoing calls.  This is on both cordless and corded (yes, we still have some) phones, including a princess phone from the 1980s.  We've had Triple Play for years, and nothing has changed on our end.  Any ideas, or will this require a truck roll?

You might want to check the ground wire near your ComCast box outside your house.  That wire may be broken or corroded.  When that happens, strong nearby broadcast signals may interfere with some of your communication devices.  This is not an uncommon problem.  The ground wire goes from your ComCast box to a long copper rod inserted into the ground.  Over time, this connection may degrade.  Your ComCast technician can fix this easily.

The ground wire has nothing to do in this case. The eMTA becomes the Digital adapter to connect the phone back to the switch at the Comcast Head end. If there was a grounding issue. It can be an issue if there becomes a live line that accidentally drops on the Comcast drop, or static voltage is on the coax.

It is a problem caused by bare wiring for a telephone cord, or a large bundle of wires wrapped up inside the wall, that is causing the phone line inside the home to pick up the Radio station interference.

The OP needs to contact the FCC regarding the problematic radio station engineers to check their end. As for the customer. Unless they have the inside wiring plan. Comcast will not touch anything inside for telephone wiring.

They would be best to find someone locally that does this work, or a retired telephone tech, to go through and look for the issue. They may still have an old Carbon protector inside, if this is an older home, or even have the old transformer plugged in or just laying on the floor, that was used for the old princess phone. Now I have seen phones actually be the culprit. Especially older phones still in use.

Well the interference vanished as quickly as it appeared.  Verizon has been doing some work on our street today, repairing wires affected by a downed tree.  I don't know if that would have any effect on Comcast's phone service, but in any case the problem is spontaneously resolved!  Thanks for your suggestions.

No it would not, for what Verizon is doing.  But it is possible that when the lines got tangled during the storm.  That it turned the system into one huge radio antenna.
