Ah okay.

Well, copper pair is dead anyways. DSL is a hack, and they have to go
through some lengths to prevent crosstalk on the high speed transmission
side of it.

I ment the audio is digitized and played back using ADC / DACs?

I know that the ILEC is still a heavy monopoly, and that the CLECs are
doomed as the ILEC moves to FTTP.

Oh. I miss being able to listen to cell phone calls.

Figures. I knew you were supposed to ask permission before pulling SCA
feeds out of FM broadcasts, but didn't know there was a full up law
against it. Wonder who wanted it. Do people still use FM SCA? I think my
car stereo can use it to get a Microsoft mobile data feed, but it's slated
to die soon.

Wow. I got a visit once for operating an unlicensed FM broadcast station
and the guy was local. Someone on a newsgroup told me who would come if
someone ever did come, and said they operate out of Chesapeake.
In modern times, it's easy for them to run a sensor network all across the
USA looking for problems. Not that they do (that I know of).
There are a number of operations that are listening to the radio stations
and fingerprinting the advertisements and songs playing on the stations,
though. Independent advertisement verification.

But modern electronics handle interference better? I can't think of the
last time I had intereference issues.
