I lived 1 mile south of the WCFL towers, 60's & 70's.
Back then we always heard the programming on the phone lines it worsened when
it rained.
Sometimes on the FM radio too.
I don't recall other other items being interfered with.
Eventually Ma-Bell came up with a special order RFI phone, that actually worked.
I had the pleasure of touring the WCFL transmitter building one evening.
The one thing I recall was the light switches did not work.
When the TX was on, 100% of the flourscent lighting was on too. :-)
Back then the antenna was in an open corn field.
These days that area is largely built out.
My guess there are dozens of circumstantial RFI issues.

PS: My crystal set didn't need a coil. Just clip it on a ground and you had
WCFL...

Subject: Re: [RFI] mysterious voices, music come from house's walls
stories from the past talk about Downers Groves homes put in near the
old WCFL transmitter...would have music coming from metal heating ducts.
The junction of the metal duct runs would oxidize and eventually grow a
bit of a detector and demodulate in the walls. Supposedly ,,,banging
on the walls ( ductwork) would clear the issue ( for a while).
fact or fiction ????
"Cumulus Media 's Berger said an expert can also check inside the wall
for corroded piping or duct work. yep I'll imagine that is the problem .
Its daytime transmitter facilities and two-towerarray
<https://en.wikipedia.org/wiki/Antenna_array>are located inDes Plaines
<https://en.wikipedia.org/wiki/Des_Plaines,_Illinois>and its nighttime
transmitter facilities and six-tower array are located inLockport
<https://en.wikipedia.org/wiki/Lockport,_Illinois>. BINGO...
