Amateurs Span Atlantic on 10 Meter
Wavelength
Plunging ahead with an increasing
amount of enthusiasm in the explora-
ton of heretofore unknown radio ter
ritory in the vicinity of 10 meters,
amateur radio operators have already
d accomplished transatlantic communi-
cations on this wave length, in addi-
ton to a number of short-distance
contacts, according to information just
released by the American Radio Re-
lay league.
The first actual transatlantic two
way communication on 10 meters was
affected between 2JN, owned by C.
X. Atwater, Upper Montclair, N. j.,
and SGT, the station of Pierre
Absolutely, at Arachon, France
These two stations engaged in con-
versation for nearly half an hour,
with good signal strength reported at
each end of the circuit. Neither sta
ton used high power
When the nations of the world met
at the International Radiotelegraph
convention at Washington recently
for the purpose of allocating all use
full wavelenghts in the radio spectrum,
engineers pointed out that the lowest
useful wave was in the neighborhood
of 10 meters, and that wave below
that must be regarded as valueless
and impractical for communication
purposes. The amateurs, who for
several years have been working ex-
perimentally on five meters, imme-
diately petitioned for band in the
of 10 meters for their ex-
elusive use. The band was given
them, and through the action of the
federal radio commission of this
country was made available to Amer
lean amateurs short time ago.
Portable Receivers Require Special
Permits in India
In case you are going to India this
summer, and in case you carry port
able radio receiver with you, remem-
Der that radio license is necessary.
Visitors in India may carry radio sets
into the country as personal baggage
provided they have obtained a special
permit.
Nicaragua Gets Broadcasters
Nicaragua, which has recently been
much in the public eye on account of
its bandits and revolutions, is now
getting interested in radio broadcast
ing. Contracts for the construction
OF a number of broadcasting stations
have been signed, according to re-
ports to Washington, and a conces-
sion has been granted covering the
construction of such stations through
out the entire country.
The concession also includes the
control over all receiving sets that
are installed after the contract goes
into effect, with the right to collect
AN amount yet to be determined from
the owner of each set. The conces-
slonaire, who is the minister of public
instruction, agrees to broadcast pres
idential and congressional messages
and speeches free of charge for the
government, as well as other propa-
ganda deemed to be in the interest
of the government or for the advance
ment of public culture
The chances are that a number of
stations distributed we'll, will do much
towards furnishing a common interest
that will do away with revolutionary
tendencies.
Chicago Broadcaster Teaches
Sleight of Hand by Radio
KYW Of Chicago has been giving
once yeek series of magical tricks
presented by Chicago magician. The
magician explains to his audience of
listeners how many of his tricks and
illusions are performed. One of these
is the stunt of placing woman in a
pine box and then saving the box in
half and later producing for his
skeptical audience the same woman
unframed. Several tricks, suitable for
performance at parties and other
social gatherings are also presented.
The magic would be equally as
Sounding and much more practical if
the set owners could be taught how
TO bring burned out tubes back to
life
