Government Will List Stations as
Fast as They Can
Qualify.

The licensing of class B radio tele-
phone broadcasting stations by the
Department of Commerce under new
regulations will enable those fans
who desire to .listen- in to the best
stations on a special 400-meter wave
without interference from some OF
the lesser lights in radio broadcast
ing.
But what stations will be selected!
As the new regulations require
minimum of 500 watts in the antenna'
with dependable and non -fluctuatins &
power, special modulation, STUDIO
and a supervised program. using
canned" music only in an emergency
or during intermission, ii Is not pc
leyed many OF the 4S7 broadcastnlg
stations can now meet the require
ments This will insure only the peSt
and most dependable entertalhnhen
on this special wave length, the oulh
of stations continuing on $50 meters
OF course, the object is just that-an
effort on the part of the depar thheh'
to permit AL" or super broadcast-
ing stations to send without inter
ference from the many stations using
36O meters so that those fans VINO
desire can receive high-class enter
tainment.
..B" station Licenses.
1t looks as If such stations as are
maintained by the Westinghouse zen
eral Electric, American Telesraph
and Telephone Company. and the De
troit newspapers would be among the
first to qualify, but even they may
have to make improvements ana ad1
to their equipment. while others Will
undoubtedly qualify; eventually as
many as fifty stations may be licensed
in class b.
Upon application through the nine
district inspectors the department Will
license "B' stations as fast as thes
qualify, but probably not more tnar
one in each city or section at hrst. IN IN
in a single district or neighborhood
where interference would occur, a
schedule will be arranged dividing the
time between them.
The "B' stations will have to toe the
mark in station efficiency and keep up
to scratch on programs. the chief rad!C
inspector states, or they will lose theiI
special wave length and revert TO 3ot
meters with the general broadcastlns
stations.
Public opinion will undoubtedly soon
come to the aid Of the inspectors and
the department in case large numbers
OF broadcasters desire class r stations
and public opinion will be the last court
interesting and instructive programs
Under the present law any station car
qualify but when they get too thick
both in the general and class Il field
the radio fans who listen in may nave
TO aid officials in making selections.
As the general public is Interested ir

selves will want to know the specihca.
