tion he can expect from his set.
Therefore to violate rule fourteen
is inexcusable: I'm all circum-
stances, except in case of signals or
radiograms relating to- vessels in
distress. all stations shall use the
minimum amount of energy neces-
sary to carry out any communica-
tion desired" This rule not only
protects the listener-in against in
terference but likewise enables the
amateur to transmit on as much
power as he considers neces-
sary for the distance he wishes to
reach. He is warned in Article

mum of energy necessary to insure
safe communication"
The law. therefore. is very definite
and very fair to both listener-in and
to the amateur. transmitter. But
the latter feels that he Is restricted
in operating his set. There is
not sufficient leeway permitting him
to open up to communicate with
his neighbOr, and ne feels IL the
bars are not raised to some extent
or he takes the law into his own
hands. that half the fun of owning
a transmitting set is removed. This
feeling is not justified. however. for
in the first place the amateur is
entitled. in accordance with the
terms of his license. to transmit
on certain power and during definite
hours. and secondly, he is free TO
transmit provided The operator
shall not wilfully or maliciously in
terfere with other radio communi-
cation" The rule continues: "Ex-
periments and practice will be per-
mitted in so far as it does not In
terfere with the service of other
stations" 1t is very definitely
stated that such "wilful" inter-
ference occurs when no listening
in precautions are taken and the
call signal of the station sending is
not repeated at intervals"
That the government sharply
pun shes viOlators of this rule is
indicated in the following excerpt
from the June issue of the Radio
Service Bulletin:

Causes Of Interference.s
II. therefore. the radio amateur
who uses his transmitter frequent
ly. keeps closely within the wave
length of 200 meters, uses only the
minimum Of power necessary, and
takes the trouble to listen-in before
opening up. he is no more restricted
in the operation of his set than
in the days when CIV. and the
radiophone were terms seldom used
Much of the interference today is
due to the radiophone transmitters,
the commercial stations which vio-
late other rules of the radio laws
and regulations pertaining to pure
wave transmission and proper mod
ulation.
1t may be seen. however, that
no amount OF radio regulation as
prescribed by law. no inspection
can be rigid enough to fully regu-
late radio communication through
such space as the limitless ether.
1t Is recommended" states the re-
cent regulation pertaining to ANA
teurs. that for the purpose of
self-policing. amateur radio deputy

their members of each locality

OF the radio communication laws
and regulations-for the minimum

be the only certain solution of the
present vexatious problem of inter-
ference.
