EMPOWERED ERA
IN BROADCAST SEEN
Capital Area May Get 5000
Watt TranSmitter of
WEAF at Gotham.

An era of high-powered broadcast
ing is forecast by Commissioner H. A.
Bellows as the coming thing on the
program side of radio. The success
of recent experiments on the higher
powers, especially in the matter of
interference, has definitely convinced
the Federal Radio Commission that
there is room for more stations Of this
character.
Up TO 5000 watts output inter
ference that is set up by stations
operating on the same wave lengths
is almost proportionate to the sta
tons power. Beyond this limit the
interference is no greater and blanket
ing does not seem to present enough
hindrance to the use Of more power,
according to Mr.. Bellows.
Significant to Fan.
To the radio fan the newly formed
conviction among members of the
commission is significant. 1t may
mean the Inauguration of high hpow-
cred broadcasting on a widespread
scale, although the commission makes
1t plain it does not invite the broad.
casters TO rush forward with plans
for altering their transmitters to take
care of heightened wattage.
High power such as Station WGY
at Schenectady has been using
100000 watts, or 100 kilowatts-ap-
parently has proved that programs
can carry over a substantially wide
effective range with greater consist.
ency than low power affords. Long
distance is not as great a factor, in
the opinion of Mr.. Bellows, as the de.

which will override ordinary natural
interferences. such as static, and
make it possible for persons within a
radius of perhaps $50 miles Of the
high-powered station to receive it's
programs more regularly and more
clearly modulated.
Reception Held Enhanced.
For Station WGY, which has been
experimenting under a special license
granting it the 100 kilowatts of power
making it the highest transmitter in
the country, it is claimed that its
newly-developed modulation tubes
have enhanced its reception quality
very greatly. Station 2xZ. expert.

The Radio Commission has just in.

use the 100 kilowatts and has grant.
