SHOWN IN RADIO
Seven 5o,o0o-Watt Broad
casters Are Already in
Operation.

Tendency In broadcasting Is toward
super power stations, and is evidenced
by the number of broadcasters in the
country already using the maximum
amount of $4,000 watts as well as those
who are applying for increased power
allotment. The Federal Radio Commits
sion's records now show seven stations
in the country licensed to use so kilo-
watts, nine other with construction ps-.
mits for erection of super-power sta
tons, and five more with applications
for construction permits pending.
The tendency toward greater power
has resulted in generally better re-
ceptlon throughout the country. When
broadcasters first sought. . increased
power in excess Of 5000 watts several
years ago there was a general clamor
among both radio listeners and engi-
neers that high power would be i'm
practical and would cause no end of
interference.
Modern Sets Onset Power.
When the first super-power stations
were built three years ago the predic-
ton of engineers was true. Listeners
with old model receiving sets located
within 10 miles of the transmitter
found 1t impossible to tune out the
signals. However, with thu rapid de-
velopment of radio receiving sets which
has taken place during the last three
years, resulting in uniformed and IN
creased selectivity, the problem of in
reference has virtually been eliminated.
With the modern sensitive receiver of
today 1t is possible to select any desired
broadcaster while within the shadow
Of the super-power stations arltenna.
ALLEGATION Of $4,000 watts to stations
has resulted in generally improved re-
ception throughout the country. In
metropolitan areas 1t has solved the
problem of Summer reception, the i'm
pact OF the high powered signal COM
pletely drowning out static and other
er, who previously could only hear the
weak local station and seldom the city
stations, now tunes. In nightly on met
ropolitan concerts.
Listeners Well Satisfied.
Statistics recently prepared by the
Federal Radio Commission show. that
there are seven 50,000-watt broadcast
ers in the country. All Of these sta
channels, and check-up on interference
shows the. listeners are we'll satisfied
with high-powered broadcasting. The
one exception is station WGY at
Schenectady, which shares time with
KGO. Other stations now using so
kilowatts are KDKA, Pittsburgh:
WEAF, New York; WENR, Chicago;
WLW, Cincinnati VITO, Hartford,
Conn, and WTANd, Cleveland. In ad-
dition, WIZ at Bound Brook, N. j.,
operates with power of $4,000. More
than 80 other stations scattered
throughout the country are employing
10000, nine Of which have coYlstruc-
ton permits for the erection Of $4,000
watt stations, and i've more have made
application.
Stations holding construction per-
mitS for $4,000 are KYW, Chicago:
WBAP, Fort Worth, Tex WABC. New
York; KNX, Hollywood; KNOX, st.
Louis: WOAI, San Antonio, Tex: KFI,
Los Angeles; WIS, Chicago; WFAA,
Dallas. Applications pending before
the commission for 50.000-watt permits
are stations WAPI, WHAN, WOwO,
VIGIL and KGO. sF
Under the regulations Of the, COM
mission, stations Of such high power
are licensed for $4,000, the maximum
provided under its own ALLEGATION, and
$4,000 watts is assigned experimentally.
