MOVIE BROADCAST
DISPUTE STUDIED
Capital Inventors Hour Crit
Cized and Interference
With 1t Opposed.

Criticism of the broadcast hour used
by G. Francis Jenkins, Washington
inventor to transmit his radio broad
cast of motion pictures is before the
Federal Radio Commission, together
with a complaint from another quarter
that station WHAM of Rochester, N. Y,
is interfering with reception of the
radio motion pictures which are sent
out from the Jenkins laboratories, at
1919 Connecticut avenue. between 8 and
8 o'clock on Monday, Wednesday and
Friday nights of each week. Under
the new ALLEGATION, effective November
H. station WHAM is given a clear
channel and its frequency is changed
from 1910 to 1,150 kilocycles, so that
it is anticipated that interference from
this source will be eliminated.
Commissioner O. H. Caldwell has
been advised by jenkins, it was made
known today, that the inventor eX-
pressed regret that I'VE can't avoid in
reference with the old crystal and

Writes to Complainant.
Robert H May of 2124 street. who
criticized the Jenkins broadcast hour,
was sent this letter by the inventor
October /:
Il am in receipt. by the courtesy of
the Radio Commission of your criti-
ciSm Of the hour we selected for our
tri-weekly radio broadcast of motion
pictures, explaining that it puts your
audible receiver set out of commission
for the hour
The hour was selected as that likely
to be the most acceptable to the great
est number of those who seek the
pleasure attendant on the pioneer re-
ception Of radio movies.
These consist of radio fans all the
way from Is to rs years of age, and
located in many States east of the
Rocky Mountains. An earlier broad
cast would interfere with the dinner
hour of those West and a later hour
would deprive the East Coasters of their
opportunity. To stop altogether would
be unfair and unkind to hundreds who
have built sets to get our radio movies.
Fortunately for all of us, most mod
ern radio sets easily tune out every
thing lying outside the broadcast band.
so that relatively little complaint
reaches us; while the spontaneous en-
thuSiaSm in many of the letters which
come to us daily makes us feel we are
giving pleasure and entertainment to a
great many.
Broadcast Interferes.
'Why don't you also try for our movies
broadcast? We think you would find
it entertaining, and you are so very
close to our station that you should
get very strong signals"
From Baltimore the Federal Radio
Commission has received this letter
from Howard Adams, jr, Of the S. M.
Hamilton Coal Co.:
LAS you are aware, Mr. c. S. Jen-
kins is at the present time broadcastlng
radio movies over his station 3XK, on
approximately 46.72 meters.
ever since Mr.. jenkins started his
broadcasting I have been picking up
his picture, and after each transmits
sion send him a report in the hope
that my observations here may help in
the advancement of television.
However, some night I am unable to
even understand his speech, let alone
get the pictures, due to the fact that
broadcasting station WHAM of Roch-
ester, N. Y, has a terrible harmonic
on Skis waves. I have taken the
matter up with the Stromberg- Carlson
Co. and was advised by them that they
were working on this matter. Up to
the present time the interference has
not decreased at all-in fact, I believe
it has i1creased-and I am appealing
to you to see if something can't be done
about it.
It do not know how much territory
WHAA1 succeeds in spelling for Mr..
Jenkins, but it does seem shame that
these experiments can't be carried OH
on a wave free from the harmonic Of
some broadcast station. In fact, l
doubt if you realize how very many
harmonics from broadcasters do show
up down on short waves, and I hope
you will look into the matter at your
earliest convenience"
