was attacked by some witnesses and
defended by others.
"Indiscriminate reservation of 81
channels for national stations" Mr..
Felix said, without power limitation
and the attempt to meet local service
needs with but 25 channels, is q salts
factory engineering solution Of a
problem which has more than an
engineering side to it. BY four power
scales the opportunity of the medium
and high power station is not greatly
restricted. At the same time a much
less rigorous economic upheaval 10 en-
tailed by q plan which permits as
much as 427 stations to remain on the
air at the same time.
"Broadcasting Is to be regulated
for the benefit of the listener; our pur-
pose must be to give him the best
possible service. not only according to
engineering standards, but standards
in terms which he will understand and
appreciate.
Throughout the entire session today
the interest Of the listener was declar-
ed to be paramount. DIR. Alfred N.
Goldsmith of the National Broadcast
ing Co. told the commission that "the
listeners service is going to be para
mount and is going to make or break
radio in any event"
Mr.. Felix said long distance recep-
ton Is unimportant. "but like a TO-
mile automobile, should be available
If wanted"
Interference Described.
Interference in Chicago between sig
nails from WRC in Washington and
XII in Los Angeles was described by
E. A. Bean, radio supervisor in charge
of the Chicago district. He said the
distance of heterodyning interference
is problematical. The two stations
broadcast on 467.5 meters.
DR.. J. II. Dellinger, radio expert Of
the Bureau of Standards, said the
farmer has been the chief loser in the
chaotic conditions. which have marked
radio broadcasting because good ra-
dio service to them is not given to the
rural districts" G. G. Furness of New
York said those stations. which are al
located exclusive national channels
will have IAN exceedingly valuable
franchise" and should have a mini
mum power standard. He suggested a
minimum of power of / 900 watts. p.
G.. Andres of st. Charles, ILL.,, sug-
gested that the band from 100 to 200
meters be set aside for broadcasting
exclusively educational programs.
Simultaneous Broadcasting.
DIR. Dellinger estimated 12 50O.watt
stations scattered over the country
could broadcast simultaneously on the
same wave length. This view was
challenged by other members of the
conference, among them 0. III. Cald-
well. president member of the com.
mission, who said he had believed
not more than six stations of that
power could broadcast without inter-
ference in sensitive receiving sets.
The effective service range of a 500
watt station was placed by Mr.. Cald-
we'll at 10 miles, but he and many
others placed the nuisance" range Of
the signal at many hundreds Of miles.
Possibility Of reduction of the num-
Der of tubes and even renewed and en-.
larged use Of crystal receivers was
seen by Ralph H. Langley Of the
Crosley Radio Cooperation as an out.
growth Of higher power and high field
strength.
Alternatives Pointed Out.
The commission has before 1t q
warning by the American Engineer
ing Council that plans contemplating
a greater number of broadcasting sta
tions will diminish rather than in
radio to the general public.
