radiophone and associated equipment

Change of Delivery.
The lectures previously broadcast
from NOF and now radiated from
NAA are rarely. if ever delivered at
the broadcaStiEg stations. The words
are spoken into the microphones 80

W aShlngton or elsewhere and car
rleu oNer'the land wires TO the broad
casting station. whence they are
radiated in space through micro
phones associated with the radio
phone transmitter
Perfect results under these condi-
tlons cannot always be guaranteed
because two principal non-radio fac
tors are thereby introduced, and over
which the naval radio experts at the
broadcasting stations have no control
One of these factors is the land line
telephone circuit. with it's associated
microphones. which may be OF high
grade quality and functioning prop
erly or of inferior gra6s and func-
tioning poorly
If the land line circuit happens II
be defective, or if one or more poor
connections are given through the
telephone exchange switchboards I'll.
speech input TO the radlophone micro
phones will be weak or distorted. or
both, and the exact equivalent vii!
unavoidably go out in space by radio
If there should be hum or Other
similar noise over the land line cir
cult, these noises will also unavoid-
ably go out in space along with the
speech. The other factor is the
method of speech delivery which MAY
be used by the speaker, regardless or
vocal qualifications.
Whether speaker uses notes, he
or she should always keep the mouth
directly in front of the telephone
mouthpiece. care being taken not I"
turn the head away while speaking
otherwise the speech intensity may
become so uneven and weak as to b.
unintelligible as reproduced by radio
If the mouth should be too close
to the telephone mouthpiece, the
speech will be "muffied" when re
produced by radio; if too far away
the speech will be extremely weak
The correct distance is about tive
inches from the telephone mouth
piece. repetition being made of tho
fact that the mouth should alway>
be kept directly in front of the
mouthpiece.
If the speaker shouts into the
mouthpiece. the delicate microphont
in the telephone mouthpiece is liable
to become packed" or broken. with
resulting disastrous consequences lin

Best results will be obtained by al
ways utilizing a steady, fairly strong
tone of voice. 4 composed manner Of
