We're picking up a radio station on our wired telephone in the main
I assumed the phone was bad, so it was replaced with a new one,
I also added a RS ground jack by the phone, but that didn't help
The other 3 phones in the house don't have this problem.
Yes, and the device is free, but Verizon charges for a service call to
put one on. 75 dollars or so for the first half hour. Plus you have
to be home when he comes. The verizon guy told me to buy a DSL filter,
I think it was, at radio shack. But I changed phones and it went
away. The "new" phone is 15 years old.
It's possible tht your new phone is actually the same maker as your
old phone, or the same weakness. Or maybe a DSL filter will solve
your problem. 15 dollars iirc.
Before we switched our phones to run off our Comcast cable we had a huge
amount of "common mode" 60 Hz voltage (on both sides of the incoming
phone line) which got really bad when it rained and the overhead lines
and power insulators got wet.
It didn't bother the couple of ancient "simple" phones in the house, but
the more modern ones which ran off wall warts had very annoying 60 HZ
hums. The olde phone company said they couldn't do anything about it
because they weren't going to put any more money into their copper
network since fiber optic lines were going to get installed in the next
couple of years.
So, we jumped ship to Comcast, leaving the hum behind.
Sound like you've got RFI (Radio Frequency Interference) getting into
that phone and being demodulatyed by non-linear components in the phone,
so you then hear the radio station.
I'm not sure what you meant by a "RS ground jack".
I'm guessing it's something you bought at Radio Shack.
But if it's not an "RFI filter" or "EMI filter" then it may probably
isn't what you need to kill that radio station pickup.
This sort of filter will usually do the job:
Or, for less money you can buy their Hard-Wired filter and install it
inside the telephone jack box.
