The Birmingham age-herald. [volume] (Birmingham, Ala.) 1902-1950, 1922-12-24

Over there a special station located
near London sent out a series of tests
each night from November 20 until
December IL on wave lengths rang
Ing from 200 to 325 metres. The low
est possible power was utilized for
this purpose, so that the supersensI-
tive receivers throughout the country
could be tuned In under approximate
conditions prevailing when the Amer
lean amateurs are sending.
In this country the stations select
ed were approved during the regu-
lar cross country relay work which
is done every night under the aus
pieces of the American Radio Relay
league. Each station had to be heard
distance of at least 1900 miles d.
rect over land--a condition which
approximates the possibility of trans
hitting across the Atlantic. One
amateur located at Ontario, Cal, not
only crossed the continent, but was
easily heard In England.
How Schedule Works
Until December 20 the amateurs on
this side of the ocean will continue
their transmission tests, starting at
7 o'clock in the evening and lasting
until 1 o'clock in the morning. The
period Is free for ALL" while the
remaining three and half hours
each evening is devoted to individual
signaling. Practically every amateur
throughout the country has pledged
himself to remain quiet during these
periods. unless the schedule permits
him to transmit.
While the amateurs OF this coun-
try are having their fling at shooting
therea1 waves across the turbulent
Atlantic, their plans call for nightly
reports from the big high powered
transatlantic stations through the
cooperation of Marconi's Wireless
Telegraph company and the Radio
corporation of America.
Every morning at 2 o'clock eastern
standard time. the big station at
Carnarvon, Wales (MUU), operating
on a wave length of 14,200 meters.
will report every American amateur
who has been heard In England. He
will send this information at the rate
of IL words minute, Five minutes
afterwards the station at New Bruins
wick, N. J. OVID, will repeat the
report. Reception in France will be
reported in a similar manner by
Saint Assse at 2:10 q. m. f. s. T.,
on $4,000 meters, and his report will
be repeated by Marion, Mass.
British to Use One Kilowatt
This year the British government
has authorized a transmitting sta.
tion of amateur construction al Man
chester, England, with one kilowatt
of power. This station will be the
center of the European transmission
to this country which begins on De-
cember %. Many French stations
have also been permitted to increase
their power for the tests. Daily re-
ports of success or failure will be
sent by the mig transatlantic sta
tons during the phase of the expert
ment, but in this case OF course the
reports will originate in this coun-
try.
The most careful arrang, ments
possible have been made. The periods
of transmissions here have been al
lotted to the various radio districts
of the country, and all other stations
have pledged themselves to remain
quiet. In England, where broadcast
ing has just begun. the British have
a feeling of horror against radia-
ton of receiving sets, and efforts
have been made to have all regenera-
tive receivers closed down during the
period when the American amateurs
are sending.
Last year 81 American amateur sta
tons were heard In England. the
first time amateur stations crossed
the Atlantic. This record has already
been passed during the preliminaries.
How far the latter will be exceeded
the next few days will tell.
