Editor Advertiser: After reading
MANY treatise on wireless interference
on the part of the amateurs, especially
the editorials in last night 3 Star, [
have seen very little in the defense OF
the amateurs.
To begin with. and as has been stated
BY government operators, their appara-
tns is three years behind time. The
amateur, taking advantage OF scientific
discoveries, either makes or buys his
apparatus, with the aid of which he
NAV time out stations, not wanted. The
United Wireless Co. uses hye-slide
tuner capable of tuning out and IN any
station desired if it happens 70 be a
few working at the same time. The
government has been offered time and
time again up-to-date apparatus, which
the wireless company proved would
eliminate interference from one 10 three
per cent. Still these offers have been
refused, and of course government sta
tons, with their old style apparatus,
continue TO be interfered with by the
amateurs. Most all experienced anna
teurs or maereial@companies generally
respect the army or navy stations, the
same way we do here, when they re-
eeiye important messages and we are
5oia to Keep cut. Sometimes inter
ference is caused by earelessness OF
government operators or by inexperl-
eneed amateurs. Sometimes the anna
feurs keep out when told to do so but
the average one after waiting half Sn
hour gets impatient and starts again.
The navy or army operators press down
their keys for several minutes ana
drown all sending and receiving which
is being done in that range. Here the
amateur steps in and says that if the
government operators can not overcome
the amateur interference what will be-
come of them IN time of war when high
powered stations of the enemy put the
naval apparatus out of commission Dy
simply holding down their (the enc
my's) keysa
Besides doing mischief the amateurs
have been many times of benefit
to the large stations when the apparatus
was out of working order and have re-
eeived and sent messages for them. I IN
not talking Of Honolulu but Of the Who'll
area where the good old e. S. A. flag
flies. In Honolulu we have two or
three stations where there is the most
up-To.date apparatus used. Some of those
have geen only invented in recent
months. It is only a credit to the
operators Of the naval station, that that
station is not out of commission yet.
They only have one-slide tuner. two
loop, aerial no potentiometer and using
a wayemeter for variable condenser,
a home made caborundum deteetor.
Their sending capacity is low, about
Two condensers instead of seven: their
spark so ragged that I sometimes
believe new amateur is trying to do
some simple wireless work with a gaso-
line engine (wire spark coil.
Our II. A. o. A.. or Wireless Asso-
citation of America has already mem
bership of over 1000 members, the larg-
est IN the world. When the time for
action arrives we viii exert power
full pressure TO oppose the Wireless
license BILL
There will be. a time not far off
when we will no more use antenna, and
the spark can be mufhed so that a
person in the next room couldn hear
a sound, where the authorities would
have hard time to fnd whence the
sparks (good and fat ones, no ragged
ones. up-to-date ones), came from. So,
We don t worry and lose sleep over a
maybe or not-be law against the anna
teurs. Thanking you for space in your
paper, [ remain, yours truly,
CHAS. T. L. LUDIS,
Electrical Constructor.

new telefunken singing spark system.
