NEW RULING HARD
ON WAVE WODBLER
Jumpers Must Keep to Lane
Assigned to Them or
Lose Licenses.

Radios prime nuisance. the "wave
w0bhleT,' must stay on his assigned
wave length under pain Of revoca.
sion of broadcasting privileges by an
order of the Federal Radio Commits
sion, effective May 3. The order repre-.
sonts one of the most important ac-
tions yet taken by the commission in
its effect on stations and listeners
alike. 1t means the elimination of the
cause Of perhaps half of all previous
interference. ana particularly The prac-
teal elimination of beat notes. often
mistaken for static in receiving sets.
Beginning May .. each radio an
nounCer must tell his audience at the
Beginning and end of the program the
frequency upon which the station is
operating. Radio supervisors will
carefully check the authenticity of the
stated frequency from time to time
and listeners are invited to report VlO
lations indicated by their dials
Under the order the commission
f1Xes 500, or one-half kilocycle, as the
maximum deviation permitted any sta
tion from it's authorized frequency.
Maintenance of a fairly constant fire.
quency-the 500-cycle limit was chosen
upon the advice of leading radio engi-
neers--is declared to be the duty of
each broadcasting station. and viola
tion of the order viii be deemed suffi-
cient cause for revoking a license.
In other words, the broadc3star
must stick" to his wave length and
not wobble or wander away 50 as to
interfere with other waves and impede
clear reception. The commission does
not prescribe the method TO be en-
ployed by a station in order to keep
on an assigned frequency, but it is
assumed that crystal control and me-

those stations not now having them.
A large number have such equipment,
and some have been cited at various
times by the Bureau of Standards as
being standard or constant frequency
stations.
The commission just now IS busily
clearing up the temporary permit is
sues, some of which have oeen de
layed. At present it appears that
about Is stations may not get permits
at all. inasmuch as they have failed
to apply This will reduce the num-
ber of stations considerably more than
the commission anticipated or down
to perhaps $50.
License issues will follow the for
mutation Of a definite plan of reallo-
eating waves and powers. The COM
mission is now working on such a
plan, and it is learned on good author
fly that no radical changes from fre-
quencies and powers now authorized
are contemplated. The basic idea in
issuing licenses will be to keep sta
tions operating as nearly as possible
under present conditions. providing
the new alignment of stations works
out satisfactorily. 1t is inevitable, of
courge, that there will be some
changes.
Two outstanding events of national
Importance will be broadcast tonight
by WRC in conjunction with a num-
ber of other principal broadcasting
stations of the country.
The first is the American Red Cross

Static again played havoc last night
with the signals of the out-of-town
broadcaSterS. The atmospherics were
steady ana emphatic in their uproar,
Dut relaxed somewhat before midnight
and gave persistent dialers an oppor-
tunity to catch a few call signals
The noise, it seemed, was more severe
On the higher wave lengths, where,
unfortunately, the most interesting
programs were to be found
The signals, however, came through
With good strength and occasionally
