! TO CUT CONFLICTS
Canada and U. S. Stations
to Cooperate as Re-
suit of Farley.
BY CARL H. BUTMAN.

Radio broadcasting in the North
American continent has now come to
such a pass that conferences with
our radio neighbors across our borders
are necessary In order to minimize
the Interference between broadcasttng
stations. The conference between the
CANADIAN and United States radio
officials held at Detroit last Monday
Is the first Of series OF similar
conferences which may soon be held
with Mexico. Cuba and probably some
of the Central American countries, II
broadcasting increases there.
Ever since the last radio conference
here, at which Director of Radio Z.
p. Edwards of Canada was present,
the assignments of wave lengths In
Canada and the United States nave
been made with careful regard to
adjacent stations across the border
and some interference has been
avoided. Early in January the De-
partment of Commerce decided not TO
use the six following wave channels,
which gave Canada the unrestricted
use of them for broadcasting II II
was so desired: 291.1, 1928. 329.o'
1858, 4107 and 434.5 meters are not
assigned to broadcasters In the states,
but are used in Canada. There is one
exception, however, 434.5 is useo py

official broadcasting station.
Canada Has Six Waves.
Canada's Is stations, therefore, have
six exclusive waves, but that govern
ment could, of course use any OF
all of the wave lengths in the broad
cast band between $50 and 545 meters,
lust as rightfulIy as United States
stations use them. However, Amerl-
can broadcasters got the start on our
Canadian neighbors by about yeaS,
and, as there are SIS OF them on the
air today, Canadians desiring 10
broadcast find it to their own interest,
as we'll as more practical, to dodge
this interference. 1t is very decent
of them and fans should appreciate
their attitude.
thew have confined their activity WIN
in a band between 291.1 and 6l6.s
meters and do not license the use OF
a channel to a border station IL
nearby United States station is using
the same wave length. A Canaoian
station in British Columbia uses the
same wave length as one OF our BuI-
falo stations, but it Is located sum
cient distance so as not to 1nteriere.
This is also true with a wave USED IN
Detroit, and another used in Porto
u,
control.
Conference Called.
Some interference existed, however,
and It was also desired to eliminate
ship spark sets on the lakes, II pos
sible.. in the interest of broadcasters
on both sides of the line. SO confer
= ence was called. Ships on the lakes
have been asked to vacate the wave
channels 600 and 706 meters and be-
low, and some of the border shore
stations have also been requested to
operate on higher wave lengths. The
results of the conference at Detroit
should go far toward better reception
in both Canada and the States and
make for amity among both radio fans
and commercial interests. It was Can
ada which requested the conference
and 1t is probable that the new alloca-
lions which win result will tend to in;
crease and improve her broadcasting
rights OF way.
Ontotrio leads in numbers of Cana
dian broadcasting stations. having "a
stations on the air; Alberta is second,
with IA, while British Columbia and
Quebec tie for third place with II each.
