50OO-Watt Plant Of South
ern Radio Corporation Is
One Of Country's Finest.

Radio fans The long watt Is nearly
at an end.
Just a few days now before the
opening Of one Of the finest and most
powerful radio broadcasting stations
in the entire South.
The San Antonio Light, in pursu-
ance of its desire to be constructive
force in the community" will coop
crate with the city's latest radio pro-
iect with the idea of putting San
Antonio on the radio map with a
large red ~"
AS a matter of fact, the new sta
ton already has been on the air sew
cral times. On various evenings for
several weeks past, fans who have re-
manned at their sets after midnight
have picked up the station. operating
as VICAR, while the operators have
been testing the wave length, modula-
ton and tonal qualities Of the big
new set.
On Friday night Radio Inspector
Dutreil, of the Fifth Radio District
made a special trip to San Antonio
for the purpose of inspecting and
checking the new plant at close range.
VICAR was put on the air with
test program at $50 D. m, while
the other San Antonio station was
broadcasting, and the inspector, sit
ting in the Stapleton Music company
store tuned in one of them after the
other to learn at first hand the diff
ficulties Of radio fans with tuning
one station out and the other station
in.
Inspector Dutreil found wears
wave to be extremely sharp-so sharp.
indeed, that he had slipped past it
and had to slowly move the dials
back on one selective set, although
the set was transmitting on 1000
watts.
And, by the way, fans, should you
be troubled at any time by interior
ence between stations, Inspector Dut-
reil of New Orleans, is the man &c
whom you should tell your troubles.
1t is his official mission to see that
all radio stations in his district keep
on their wave and refrain from the
slightest interference with others.
WIDE WAVE SPREAD.
There is a spread of 1865 meters
between VICAR ard WOAI. The new
station operates on a wave of 263 me-
tiers, while the allotted wave of WOAI
is 1865. Even comparatively simple
one and two-tube tuning controls
should be able to separate the two sta
tons without great difficulty, if both
keep to their proper broadcast chan
nels. 1t is easy for the fans to de-
tect which is the transgressor by no.
ting the strength of signals when their
sets are tuned closely on the wave of
one or the other. In other words, if
VICAR comes in with any considerable
volume while a listener is tuned for
WOAI, then VICAR is off its wave
and needs correction. Conversely, the
opposite is true if WOAI is heard
loudly when the receiving set is tuned
to VICAR.
For the benefit of those having the
simpler tuning controls, it may 6e
mentioned that simple and inexpen-
sive wave trap will do much TO rern
edy the difficulty. Thirty turns OF
any small wire, wound in a three
inch circle, on cardboard tube. oil
even around the fingers, and shut
ed" by a variable condenser-any var
liable condenser will do-will turn th'
trick. The Light will publish con
struction details and diagram Of sucl
a wave trap before VICAR regularly
goes on the air for nightly concerts.
MADE IN SAN ANTONIO.
The new station which the South

a wave like knife edge.
