AZ STATIONS CARRY
COOLIDGE SPEECH
LARGEST Chain Ever Joined for
Simultaneous transmits
sion Hooked Up.

The largest chain OF radio stations
ever joined together for the stimuli
famous transmission of any event
were linked today by the National
Rroadcasting Co. to carry the voice OF
President Coolidge from the House OF
Representatives to the radio audience
of the United States. Forty-two sta
lions from Portland. Me, to Portland.
Greg, south to Atlanta, Dallas ana
Los Angeles, were connected by spe-
cial circuits for broadcasting the
Presidents message.
The geographical location of the
stations in the nationwide chain was
such that radio listeners in every town
and hamlet in the country should have
been able TO hear the Presidents
voice, and the broadcasting ofthe cere-
monies by four short-wave transmit
tiers in addition TO the ~ stations un.
doubtedly allowed Mr.. Coolidge's
speech to be heard III many foreign
countries.
A microphone installed in the House
carried the ceremonies by special cir
cults to New York. from which point
other special circuits conveyed them
through the chain of AZ stations. The
short.wave transmitters which also
broadcast the event included two at
KDkA, one operating on 6S meters
and the other on II meters. and two
at Schenectady-2XAF which used
the S2.7-meter wave channel, and
2XAD. which broadcast on % meters.
Booster stations for popular broad
casters may solve the problem of at.
tenuation. In long-distance telephony
1t is necessary to boost the current
ever so often; otherwise to get
through a message in normal volume
at a distance an inconceivably power
full current would be essential at the
start. The major loss is one of at
tenuation. this loss being greater for
metal conductors than for ether.
The attenuation Of the ether varies
from night to night, and it always is
strongest in the daytime. II the waves
sent out by a broadcaster could be
boosted at certain points, and as neces.
stty demanded, reception would be
tolerably perfect.
Boosters would be less expensive In
the long run than linked stations.
There are great many problems,
however. to be ironed out in the actual
work Of boosting the wave, with many
doubts as to the success of the plan
az least within the next few years.
Few conservatives nowadays dare to
say that things can't be done. They
just set time limit and usually play
eaIe by making a very brief one.

Continued improvement i'm recep.
non conditions was noted last night.
Except for fading, the chronic aifnent
OF some stations, and considerable
heterodyning. there was little to com
plain about. Signals came in with
clarity and good volume, and static
manifestations were rare indeed.
Here's one page from our log last
night which could not have been du.
plicated the latter part of last week.
when reception was at it's lowest ebb
OF the season perhaps: WABF, Kings.

WRNY. New York; WCCO, Mime.
apols: WGHB. Clearwater, Fla:

new station at Niagara Falls whose
announcer seemed to be timid. about
giving its call letters.
