internal disagreements about the chimes

Subject: Use of Chimes

The subject of chimes comes up periodically, and as a matter of
fact the number of complaints received since the automatic chimes
were installed is less than existed with the old hand-struck
chimes.

My personal feeling about chimes is that they are not entirely
necessary. They are used as a signal of constant amplitude to
attract the attention of the personnel at the telephone company's
repeater points. In order to make these chimes as unobtrusive
as possible we have from time to time lowered the output level and
recently it has been lowered to a point where we receive com-
plaints from the telephone company and the network stations that
they are not loud enough to attract attention, the purpose for
which they were originally installed. Other means of attracting
the attention of network station personnel have not been accept-
able as it was felt that the chimes represented the trade mark
of the NBC on the air.

I personally feel that the cue used originally should be entirely
satisfactory for the handling of switching at repeater points and
network stations, such as the words "National Broadcasting Company."
As it stands now we use the cue words and the chimes. If it is
going to be the Company's policy to do away with their trade mark
on the air by deleting the chimes and substituting a word cue, then
the operators at the repeater stations and announcers and operators
at network stations will have to pay stricter attention to our
program continuity in order to pick up the cue for switching and
announcing. Perhaps this closer attention to our program continuity
would be a good thing.

          What would you think of trying 
this for a while, to see how it would work? 
In your opinion, are the chimes necessary
as a trade-mark?

                          Replying to yours of the lst concerning 
the use of the chimes.

                          I think the chimes have become extremely 
monotonous, and I have often felt that if the switching can be handled 
as promptly in some other way it should be done. I realize that 
some sort of signal is necessary. I do not particularly care for 
the phrase "This is the National Broadcasting Co" because it is too
much like CBS. We use that phrase anyhow just before the chimes.

                          If you want my own personal feeling, it 
is that we could devise something much pleasanter to listen to than 
the three-note chime -- something with real music in it and 
that could be changed from time to time to relieve the monotony and 
still retain the identity.

                          There isn't any question but that our 
present chimes mean the National Broadcasting Co, but I doubt 
very much whether the public knows that it is NBC or CBS that is 
ringing them.

                          I would try anything but these chimes for 
a while anyhow.

Subject: Automatic Chimes Circuit

When our automatic chimes were first designed the circuit diagram showed a 4
mfd condenser across the output circuit. Investigation discloses that the 4
mfd condenser is not connected across the output circuit of the chimes
installed at some of our offices. Will you please instruct your maintenance
supervisor to properly install a 4 mfd condenser in the circuit of your chime
machine as soon as possible. This condenser will reduce the level output of
the chimes by 4 or 6 db. It will also remove harsh overtones and results in
a more pleasant tone to the ear. The elimination of overtones results in
apparent volume reduction even though the level is readjusted to normal. The
4 mfd condenser has been installed across the New York chimes and the level on
the chimes circuit has been adjusted so that the maximum peak kicks twenty
degrees on the volume indicator.

Please advise by telegram when this work has been completed and the level
properly adjusted. We are interested in comparing the quality of your chimes
before and after you make this change.
