Hear radio station in background - Anyone else?
awara:
I have been using Obi 200 since Nov last year. Setup GV and then CC a few months later for the 911 service. Everything works well.
I have noticed something odd over the past few weeks. When I receive/make a call, I hear audio of a radio station playing in the background. Did not spend time to figure out which station it is. The other party does not hear anything, just me. And I think it is a local radio station as the commercial announcements reference nearby locations and/or announce phone numbers with local area codes. Just this evening, I was hearing part of the Dan Patrick show and then commercial for Fox Sports and then something about Iowa State basketball and firing of Atlanta Hawks head coach.
And to be clear, both callers do not have any radio turned on. And I am the only one who hears it. The other party shared that they did not hear anything. This has been the case when the other party is on a cell phone (family member today) or on a business line such as my doctor office (two weeks ago) or my employer's HR benefits center (three weeks ago).
Really odd. Anyone experienced something similar? Where does one even start trouble shooting something like this?

Move the Obi to a different location and see if it stops

Try another phone.

Decades ago I worked in AM radio. A listener was using a reel to reel tape recorder with an un-grounded mike (or aux) wire which picked up the AM signal and it was demodulated.
My bet, something along your chain is un-grounded and is picking up a local AM broadcast tower nearby. I have seen it on regular landline telephone lines.
Radio and television stations in the U.S, identify themselves at various times but always at the top of the hour.
The phone company oftentimes had filters for landline, but if you are not using one, then you have to investigate yourself. When this happens, can you move your hand around each item, OBI, cordless phone, etc to see if the signal increases ort decreases. The item you touch may well be the culprit.
The cure can be something as simple as a ground wire or a capacitor to shunt the signal to ground.
You might look to a local "Ham" amateur radio operator for help (not that it is their fault, but they are great at looking fo this type of thing).

I remember almost 70 years ago that I purchased a 3 tube amplifier. (35Z5, 50L6, and I think a 12BY7) No power transformer as it was direct to a 120V plug. Sometimes the chassis was hot. That's where I learned electricity can bite. I connected about 50 feet of twisted 2 conductor cable to another speaker. I was trying to construct an intercom. Well at my age (7 years old) I didn't know too much about matching impedances and heard some music and talking. I was listening to the local AM radio station. I learned to solder at 6 years of age.
For those young people who don't know what a tube is, it's like a transistor that is enclosed in glass that gets hot to the touch.
