%. to be known as station WGBS.
The Philadelphia store of Gimbel
Bros. has met with such success in
broadcastinS through its station
WIP-that the New York store de-
cided 10 start a similar undertaking.
The station, with it's studio and
operating rooms, will be open TO the
public during the regular business
hours OF Gimbel Bros.-9 TO $50. Be
cause of unique arrangement, tor
the first time people will be aole 10
witness the entire operation OF a
broadcasting station. 1t is on the
eighth floor of the store, on the
Thirty-third street side.
The wave length of the new station
will be GIG meters. Its equipment is
the latest and most highly developed
type for broadcasting, consisting or
a standard Western Electric 500-watt
tranSmitter and amplitier. In order
to insure absolute freedom from the
hum or ripple which is heard when
stations are operated from generator.
storage batteries viii be used
throughout for supplying power.
The batteries are arranged in four
separate banks---ore for the recelN-
ing apparatus, another for the ampll-
fer, third for the tilaments of the
transmitting tubes, and fourth
which delivers 1900 volts for the
main transmitter power. These bat
teries are all of the glass -inciosed
type. and SO constructed as to remain
dry and free from odors at all times.
3O7 Feet Above Ground.
A four-wire antenna is used, sup
lace Sta aal
1877 feet above the roof of the store.
The combined height of the building
and the masts make the antenna 307
feet above ground. thus insurinB
freedom from the effects of surround
ing structures which might hamper
transmission. This station will be
visible from nearly all parts of the
city, for an electric sign with the call
letters will be mounted at the top Of
the towers.
The station is separated from the
rest OF the store by double glass par
tittons. so no outside noises can be
heard. Entering the new station,
there is the reception room. where
the artists await their turn. Here
special telephone switchboard has
been installed for the convenience of
those who wish to call the station
during operating hours and also for
the use of those VINO broadcast. Ad-
joining is the office of the director of
the station.
Next is the studio itself. where the
broadcasters appear before the micro
phone. This room is 25 feet square
the size which has been found most
satisfactory for broadcasting. To in
sure the best possible acountics the
ceiling and walls have been specially
treated. Particular study has been
given to the studio arrangements. so
that noises may be softened, and yet
the most delicate notes do not lose
their quality, which often happens
when the deadening effect Is carried
too far. Over each door Is a small
red light, which automatically lights
when numbers are being broadcast,
warning those in and near the studio,
to insure quiet.
Operating Room. :.
the transmitter, control board for the
amplifers. power supply control board
and receiver, is on the other side of
the studio, One operator keeps
watch on the transmission to prevent
distortion or irregularity in the re-
production of the program. A loud
speaker in the operating room en-
ahles the operator to hear every
sound from the studio just as it is
heard by receiving sets many miles
away. The smallest vibrations are
recorded by meters on the control
board, so the transmission is checked
by both eye and ear. Another opera

mitted from the station and also
watches for distress signals from yes
