Special Dispatch to The Star
HARTFORD. Conn, August L.
Upon the urgent application of the
American Radio Relay League. the
national association of radio ANA
teurs, over an extended period of
time, the Bureau of Navigation, De-
ized supervisors Of radio to amend
amateur licenses on application of
owner to permit the use OF special
bands OF short wave lengths without
quiet hours. This action removes
many Of the Objectionable restric-
tions put upon the transmitting ANA
teurs because of the necessity for CO.
ers, and at the same time minimizes
rather than increases the interfer-
ence problems affecting both classes.
Effect Of New order.
Within few weeks many ANA
teurs who have been using the wave
lengths from 150 to 200 meters will
have adjusted their stations to oper-
ate on one or more of the new bands
below so meters, which will result in
further separation OF the general
broadcast and amateur wave lengths
and a substantial decrease of anna
teur radio interference with broad
casting. The new wave lengths as
signed to amat eurs are--75 to 80 me-
ters, 40 to 43 meters. 90 to 22 meters
and 4 to meters. The use of these
bands is restricted to CIV transmit
ters entirely.
The amateurs, for whom the recent
extension of quiet hours has proved
irksome, will find in these shorter
wave lengths a solution of their
problems as concerns tie hours OF
operation. for the order to super
visors specifies that quiet hours"
need not be observed on any. of the
bands below 80 meters. although they
must of necessity be continued in full
teur waves OF $50 to 200 meters ANA
teurs are advised to take particular
note of this fact.
Is Result Of Careful study.
For a number Of months officers OF
the American Radio Relay League
have realized that the continuation
Of silent hours for an indefinite Pc
riod OF time would be likely to in.
crease the tension existing between
amateurs and listeners. and complete
harmony could be brought about only
by the assignment of shorter waves
for amateur use. The Department OF
Commerce also appreciated the sit
y
| certain extent by issuing expert
mental licenses, which permitted GER
tain amateurs to operate on 10(
| meters or lower. The present order
Of Commissioner Carson. however
opens up the short waves to the rank
and file of the amateurs. which, with
the elimination of silent hours, con-
forms with the desire Of the amateur
organization.
While the new regulations are de-
n nj h
lens much confusion can result by ar
incorrect Interpretation, and so anna
teurs desiring to take advantage OF
these new privileges are advised not
wave length until they know what Is
expected Of them. They must frs,
make application to the radio super
visor of their district to operate on
any one or all of the new wave
lengths, and get their licenses prop:
erly amended. They are also asked
to take note of the fact that they
must use a coupled circuit In the
transmitter. A provision IL made
that silent hours will not be per-
mitted if the station Is situated so as
to produce Objectionable interference
with "other services"
Special Privilege Explained.
The regulations state that special
amateur stations will not use wave
lengths above 200 meters. although
they may be authorized to transmit
on the band from 105 to 10 meters
in addition to the waves assigned for
general and restricted amateur use
The department wishes to have ii
understood that the additional privi-
leges granted are necessarily tenta-
tive because of the rapid develop
ment of radio communication which
may in the future make still further
changes in wave lengths necessary In
order to maintain harmony.
