Jenkins Says He Will Soon Be
Able to Broadcast Movies
for Home Reception.

Whatever else may be said about
television, c. Francis jenkins insists
that it is coming sooner than the ex-
perts and THE Dunkers" think. The
Washington inventor definitely promises
that he will soon be able to transmit
moving figures and motion pictures
taken from strip films for reception via
the ether on specially built receiving
sets.
These sets will be relatively simple in
construction, and will probably be
known as "Radovisors," said Mr.. Jen-
kins. The inventor who has been TAX
ing out scores of patents on visual
radio apparatus of his own develop
ment, declares that visual radio today is
comparable to the early crystal set re-
ception of audible radio, and stoutly
maintains that developments from now
on will be rapid.
The "Radiomovies" which Mr.. Jen-
kinS has been broadcaSting from his
own experimental station here in Wash
ington are likened to early motion
pictures. They are in silhouette, he
says, because the width of the broad
cast band legally permissible is not
great enough to transmit them with
proper light values.
Mr.. Jenkins has obtained license
from the Government to employ a 100
kilocycle band. which represents a path
in the ether ten times wider than the
one he is now using in the experiments
he is conducting daily with the coopera-
ton of host of amateurs scattered
throughout the country. He is now en-
cTo in RI i1,o 1An f1.of1
mitter and expects to have it in opera
ton within few months
MY answer to the oft-repeated state
ment that radiomovies and radiovision
may not in reason be expected for home
entertainment in this generation" said
| Mr.. jenkins, 'iS to refer my adviser
| to the hundreds Of amateurs east of the
Mississippi who fascinatingly watch our
| present pantomine picture in their re-
ceiver sets.
II am now," he added, building a
| transmitter, designed on an entirely
new principle, with which, in common
belief with other skilled engineers who
have seen it, we confidently expect to
'broadcast not only movies, but actual
inaugural ceremonies and like national
events, base ball and other outdoor
| sports, theatrical performances and
/
ment-and we will begin some of it this
very next Summer"
An effort by other visual radio ex-
perimenters to obtain permission from
the Federal Radio Commission to util-
ize the normal broadcasting band for
| picture and television broadcasting has
been partially successful. The commits
sion has issued an order permitting
picture and television broadcasting from
now until January 1, 1929 within the
broadcast band between $50 and 1900
kilocycleS.
Because the whirrs of the signals
carrying vtssea, iadio are sources of in
| terference. ale evening hours from six
to eleven may not be used for these
transmissions. Neither may the tele-
vision experimenterS occupy a band oi
frequencies wider than ten kilocycles
The extent of such broadcasting after
January will depend upon ensuing
interference, popularity of the visual
transmisSions with the general public
and the limitations which may be i'm
posed under the International Radio
| telegraph Convention.
