Evening star., 1923-06-24

traffic manager of the American Ra-
dlo Relay League, has prepared a
schedule by which amateurs will
communicate with the expedition.
WNP will transmit on wave lengths
of 1S5. EGO and 800 meters. although
the 220-meter wave length will be
that most commonly used. Donald II.
Mix, radio operator on the Bowdoin
in the employ of the American Radio
Relay League, who is to accompany
Capt. Mcmillan, will send a report on
Monday morning each week or as
soon thereafter as conditions permit
He will be allowed to communicate
with amateurs every morning when
feasible.
According to the schedule. which is
on eastern standard time, WNP will
stand by from 10 pm. to midnight for
press reports from Arlington, at
midnight for reports from MSS U7,OoO
meters); 1 a. m. to 1858 a. m, WNP will
communicate with amateurs; am.
to 4:59 am, provided communications
has not been established with anna
teurs, WNP will attempt to work
stations operating under a limited
commercial license; am. to am,
the Bowdoin's station will again try
amateurs.
The radio station MSS is to be en-
ployed to report the results of WNP's
efforts to get message through, pro-
vided the Bowdoin'S operator was
wholly unable to establish two-way
communication. Amateurs are being
depended upon to keep in touch with
the members of the expedition
throughout the entire journey. Mes
used in emergencies and the amateur
receiving such a message will be ad-
Vtsed promptly as to its disposition.
Radio Aids Schoolwork.
There is no cutting" of the gen.
eral science of class at the Wood
ward High School, Cincinnati, when
the subject of communication is
scheduled for study. The freshmen
CLASS, under the supervision of DIR.
l.. ID. Peaslee of the school, and radio
broadcasting station WLW of the
Crosiey Manufacturing Company, are
given practical demonstrations of the
methods of communication. The
class had been taking up this sub
Ject from the origin of man up to
the point where he may commune
cate with his neighbor by means of
the radio broadcasting apparatus.
4 The general science class. COM
posed OF almost 400 pupils, was di-
Vided into groups and each group
given a period for the reception of
the broadcast music. A single tube
receiver, with a loud speaker, was
used for the reception and fine re-
suits were obtained during the six
concerts given. The. set was built
by Fred Schoen, one of the pupils.
This form of teaching Is new and the
pupils take greater interest in their
studies than they would where only
the laboratory and textbook meth
DDS are employed. In order that a
better understanding might be had
or the way the music was sent into
the air, the class visited the broad
casting studio Of WLw. While the
class was in the building a visit was
made to the factory, where the IA
nous Crosley radio receiving sets
are manufactured
This idea of practical instruction
In scientific work is but the start of
what will be a regular thing in the
near future. Take the class in
geography. for example; the subject
Is Africa. The pupils look at the
country on the school movie screen
and the natives speak to them via
radio. Surely, this is no dream. but
scientific possibility which may be
utilized with practical results. The
class in political science might be
assembled and the debates in Con-
gress or the message Of the presi-
dents OF the councils can be heard
at the very moment they are given,
despite the fact that the students are
miles away from the speaker. Ra-
dio Is a marvel of a marvellous age
