BY THE RADIO EDITOR.

courage in opening two television
broadcasting stations in addition
to manufacturing commercial
televiSion receivers, he goes on to
outline the future of television.
He sees televiSion developing along
lines similar to those taken by
radio, namely, first, the expert
mental days, with the expert
mentors taking part with home
made equipment; then the grad
ual crystallizing of practical
system based on knowledge
gained in actual work, followed
oy the mobilization of the essential
capital, personnel and production
facilities for the creation of an
industry quite as well as the
founding of a national institu-
ton"
AS to the possibility of tele-
vision competing with the movies,
DR.. DeForest's answer Is, II can
not conceive of television elimi-
mating the motion picture. The
two serve totally different ends.
TeleviSion will be the Spon-
taneouS preSentation-haShed be-
fore the audience for immediate
enjoyment or enlightenment
born and dead in a fraction of a
second. The motion picture
Is recorded permanently and made
available to any audience at any
time and any place. Just as
the photograph industry has
joined hands with the radio
so must televiSion and the motion
picture join hands in the future"
PLANS to rebuild the transmitter
Of WEAF, making it the most
modern and efficient radio trans
mitter in America, have been an
nounced by the National Broad
casting Co. The work, which will
be started Immediately, is esti-
mated to cost approximately
$500, 900.
WEAF, one of the best known
stations on the air, Is operated
with power Of $4,000 watts. No
increase in power Is contemplated
in the reconstruction work.
One hundred per cent modula-
ton will be in effect when the re-
construction work is completed.
according to o. B. Hanson, man.

meditation, Hanson explained.
means practically perfect trans
mission OF everything picked up
by the m1crophone and will give
listeners high and low notes here
tofore- inaudible from radio re-
ceiving sets.
Reception from WEAF will be
generally improved, it is predicted,
and there will be a great improve
ment in reception in certain parts
OF Manhattan where the stations
signals now are difficult to tune.
The most up-to-date radio
broadcaSting equipment made will
be used in the rebuilding of the
transmitter. A new type of high
power vacuum tube, the UV862,
will be utilized in the recon-
structed transmitter. These tubes,
which stand five feet high, re-
quire 80 gallons of water per min
ute to cool them. In order to
facilitate cooling Of tubes an out
door cooling pond will be con-
Structed.
Use of improved tubes will make
it possible to use four tubes where
16 are now used. Among the new
type tubes to be used will be q
special rectifier known as the hot
cathode mercury vapor tube. The
first three tubes and all aSso-
ciated circuits, including the rec
tifler and crystal, will be supplied
in duplicate.
T z. PHILLIPS, Washington's
popular trombone virtuoso,
who played regularly for several
years over WJSV and stopped
when the station moved it's studio
to Alexandria, Va, will return to
the air Tuesday evening for q
series Of broadcastS over VOL.
When Phillips left WJSV he felt
the radio audience had heard
enough trombone music for a
while and decided to take long
vacation away from the micro
phone. But letters began to come
to him in increasing numbers tell
ing him he was missed on the air.
He received 40 last week, which
convinced him that radio listen
erS like trombone music.
Phillips claims to be the only
tromboniSt who was ever ap-
plauded in a church. He played
several hymns on his trombone in
Pittsburgh church recently and
the congregation showed its ap-
probation by applauding. And he
has a letter from the minister to
cIInnort his claim
