Stereo destroys FM coverage. Those engineers were right.

And those that were purists and held to that belief....are all out
of
business.



Not so much. I encounter one or two non-stereo stations every
week
when
I'm on the road.


Please name them and their location.




I hear them when I'm on the road. I don't have time to catalog
them.

The last two I heard this past week were in southeastern Missouri
and
southern Illinois.

I don't know Peter...it sounds more anecdotal than anything....



No different than your assertion, my man.


You made a generalization about how many stations are still in mono...I
asked you to back up that statement...and you couldn't.



Just as you made a generalization about how many stations weren't in
mono. Also without any support.

I'm sure you don't drive the backroads with a pad and paper recording
calls, city of license, and whether the pilot is lit. Neither do I. On a
road trip, I may hear 15 radio stations a day. I don't record the calls.
And they may be 40 miles from where I'm rolling at the time. The only
reason I noticed the stations I noticed is because the pilot wasn't lit.
But I certainly didn't spend any effort to find out who, or where, they
were.

I might suggest this: The next time you travel, scan the dial. See if
you don't find a couple, yourself.

And then see if you can recall the name and location when someone asks
you the following week.


A large number of recent FM conversions (sports/talkers) are extinguishing
the stereo lamp. No need for stereo on these stations, and it does save a
small amount on energy bills and increases the SNR on the fringes.

once again, as jo jo asked....can you name one that has extinguished their
stereo pilot?

i think a lot of people use the stereo light for tuning so it might hurt
listenership even if its not needed.


That used to be true. FM Mono Mute was commonplace in home
receivers. Until better designs permitted lower noise stereo
listening. Keep in mind that many stations killed the pilot during
mono programming. Some NPR stations still do. WBEZ, Chicago still
does this. So does WFMT. Though mono programming is rare, today.
Today, selectable FM stereo itself is comparatively rare in low and
midlevel receiver design, with most FM capable receivers simply
hardwired to stereo, allowing the 'Blend' circuit to handle low
signal noise avoidance by progressively combining the two channels
as a function of signal strength, until eventually deep fringe
reception is in mono. So FM Mono Mute is no longer a useful
function, and like selectable stereo, is not included in many
receiver designs. In fact, many car radios no longer even include a
stereo pilot indicator. GM Car radios haven't included a stereo
pilot indicator for a number of years, now, or even a selectable
Mono function. The blend circuit, instead, reduced stereo separation
to control low signal noise, so there is no loss of reception during
mono broadcasting. I've got two Walkman portables that do not have a
stereo indicator, nor selectable mono reception, relying on a blend
circuit for FM noise control.
