MESSAGES ARE CARRIED
ON ULTRAVIOLET RAYS
Experiments in Telephony at Uni
versity of Bologna Show
New Advance.

Light-ray telephony seems to be the
most recent advance in wireless
transmission. The United States con.
mercial attache at Rome reports that
experiments at the University of 20
logna have demonstrated the POSSIBLE
ity of transmitting speech by teleph-
ony over ultraviolet rays up to dis
tances of 16 kilometers.
The transmitting apparatus includes
a microphone, Just as in radio, and a
mercury Vapor quartz bulb, the source
of the ultra violet rays. Action is in.
duced by vibrations in the mierophone.
which vary the intensity of the rays.
This variation is then projected by
special refectors. similar in principle.
1t is believed, to the rejecting anten-
ma of the beam radio transmitting an.
tennae. Reception is achieved bv
means of Photographic sodium or DO.
tassium cells. The current or i'm
pulses received on this cell are ampli.
fed by vacuum tubes, as in radio re.
ception, and led to the receiving tele-
phone, which in turn transforms the
current into audible vibrations, repro
ducing the original voice picked up BY
the transmitter.
Whether an electric current is actu.
ally transmitted over the light rays
as In radio transmission the modu-
lated waves follow the carrier, waves
or whether some more novel means
OF transmission has been effected is
not made clear in the meager reDorts
received by the Commerce Depart-
ment. The device, however. seems TO
have proven practical and to include
some of the directional properties of
the beam radio systems so popular in
Europe.

RADIO GOSSIP AND NEWS

Broadcast listeners, most of whom
are preparing to stand by either late
Tuesday night or early wednesday
morning for the general shifting about
of broadcast assignments, should by
all means secure a new log of stations.
Otherwise they will be unable to find
their old friends. 1t will be almost as
necessary as it would be to get a new
phone book If the numbers were all
switched about overnight.
Nearly 900 of the present 694 active
stations have been moved up or down.
as the dictates of public service led
the Radio Commission to change
them. Some oldtimers may not come
in as we'll as formerly, since many
have been reduced in power; on the
other hand, some may come in strong
err than ever with increased power.
In general, however, it must be re-
membered that there are only very
few high powered stations now. the
limit being 80 kilowatts.
Fans should not forget two things
it is almost Midsummer, with consid-
cradle static, and conditions should
not be judged now on the basis of
Winter reception: the other thing is
that the commission is not yet finished

Constant Voltage Best.

If one is given choice of operating
the filament of a vacuum tube with
constant current or with constant
voltage there should be no question
as to the selection because the latter
is by far the most important in that
1t prolongs the life of tube. 1t
should be understood, of course, that
if excessively high voltage is applied
to the filament, additional electrons
will be boiled out OF the surface and
the tube will be better than it was

poses, however, constant voltage
applied to the filaments will prelong

LISTENERS LICENSES
DECREASE IN AUSTRALIA
Discomfort Expressed Over Pro-
= gram Material Causes
Much Concern.

Broadcast listener licenses seem to
be falling off in Australia. and the
postmaster general is greatly con-
cerned because of discomfort expressed
in the quality Of material composing
the programs offered the public. Only
about $4,000 fans are now on the lists.
Listening fees range from % to 80
shil,ings year, depending upon the
distance the receiver lives from the
nearest transmitting station.
Crystal sets are on the wane, it is
reported, and tube receivers becoming
more popular, as most fans desire
leud,speaker operation. America is
said to supply about 80 per cent of
the apparatus, with Great Britain and
France and even local producers fol-
lowing. Despite the lack of apprecia-
ton, Australia is rated as fourth in
general interest in radio reception of
the English-speaking countries. Pri-
vate control of broadcasting is liter
ally prohibited since the government
requires control over the broadcasting
companies.
A strong preference for ready-as-
sembled receivers is manifest in Aus
tralla, where homemade sets are not
as popular as in the past. American
made sets seem to hold up well and
remain the most desirable. =

mating current of 10 volts into direct
current at the proper voltage for
radio set operation. They do not
mean eliminators, storage batteries
and chargers, automatic chargers and
the like, but an arrangement where
by the tubes of a radio set will draw
current directly from the house lines
and at the house lighting voltage.
1t requires a new type of tube.
Various forms of Notwithstanding
devices are coming on the market
with amazing rapidity but many of
them are having a transitory exis-
tence. All this is believed to be but
preliminary to the true electrical
ton of radio sets. In the last stage,
or sometimes in the last two stages,
of radio application it now is pos
sible TO use large tubes which operate
directly from the house lighting socket
and at high voltage, but as yet this
is not adapted for radio frequency
amplification and for the deteetor
stage where slight variations are so
greatly amplified as to produce con-
siderable trouble at the final output.
The whole trend, however, points in
the direction of using raw" lamp
socket alternating-curre energy for
every stage in radio reception. That
Is what is meant by complete cleo
IRRIGATION in radio.
The amateurs of the country could
aid materially in shooting radio
trouble" Commissioner o. H. Caldwell
suggests to the American Radio Relay
League in a letter sent to it's presi-
dent, Hiram p. Maxim. Commissioner
Caldwell, who took an active interest
in amateur radio work as early as
1908, wrote as follows:

BEAM WIRELESS STARTED.
Service Between Australia and
Great Britain Operating.

The beam wireless service between
Australia and Great Britain is now
operating, advices from Melbourne
state. Since rates for transmission of
messages are considerably lower than

expected. .a
Secrecy also is assured. since the

NEW USE OF CRYSTAL SET
Can Provide Check on
Reception.

That little crystal set purchased
several years ago, before becoming a
real radioist and purchasing the big
set that brings in so much entertain
'nent, still can be of service. If one
has cast it aside or put it up in the
attic, it should be got out and pressed
into service at this time. 1t is one sof
the most convenient checks on nightly
radio reception.
1t should be used in such a way
as to prove whether or not the inter
ference that is being heard is in the
air or in the large receiving. set. First
tune the large set for the local sta
ton and note whether or not there
is much disturbance. distortion or
static. Then listen through the ear
phones on the small crystal set to the
same program. If no noises are heard
with the small set it is certain that
what is heard through the larger set
Is of some personal" nature: hum
ming because of the eliminator, dis
tortion because of the wrong veltages
applied to the tubes, battery noises,
defective tubes or poor tuning.

Rnilt.in Radio Sets NOW.

The radio set is no longer some
thing 70 be bought and kept in a
dwelling; it is a fixture, like furnace
or chimney. They are building them
in today and wiring the rooms for loud
speaker or earphone plugs.
Antenna wires of various types and
lengths are now built into the walls,
attics and cellars or even doors, so
the directional feature may be util-
lied Conduits lead to the basement
from the living room where the set is
operated. so that batteries, if any,
may be kept out of sight. Some light
circuit power sets go on and off with
the lights in the room. others equipped
with Illuminated dials may be oper-
ated in the dark. Cleared with time
devices or alarm clocks, they may be
adjusted to start operating at a GER
tain time or for a definite program,
or may be turned off at any hour
when the family using retires-sOme
of us are very forgetful.
Earl Ennis of San Francisco, a radio
observer, states that sets may be SO
arranged as to start the day automat-
ically, calling the folks from bed, pro-
ducing the setting-up exercises. skip
ping embarrassing events until the
ball game goes on in the afternoon,
and furnishing dinner music and sre-
cial programs during the evening. He
thinks soon we will leave them tuned
in all the time, but turDed off when
we want little quiet in our homes.
One possibility is to connect the set
with burglar alarm. SO when door
or window is opened the set starts
broadcasting and the would-be burg
lar thinks the family is home and
awake.
So many varieties of electrically
operated sets have been offered to
the radio public that there is con-
siderable confusion over the predic-
lions that in the near future the
modernized outfit will be a complete
electrical device. Since the public
thinks this already is realty, nat
urally the prediction of radio engineers
is somewhat puzzling.
The situation is cleared up, how
ever. when one knows exactly what
the engineers and manufacturers have
in mind. They do not mean inter-
mediary devices for converting alter

shorting of Terminals Brings in
Music,

Some oddities occur in radio owner
ship and operation, and il one is alive
to them they make interesting facts
for consideration.
h This came to the attention of one
.radioist recently when he was wiring
IN the loudspeaker. The set was in
operation at the time. and in hand
ling the wires somehow he got the
terminals crossed. Immediately there
was soft tinkling of tinny music
from the set itself rather than from
the loudspeaker. This little shortlng
of the speaker circuit combined with
the circuit of the audio filter that was
built into the set at this point, pro-
duced a miniature speaker.

Means of Communication.


In an effort to develop suitable
means for carrying aerials aloft from

which lifted a 500-foot aerial.
Together with Samuel F. Perkins,

Pierce and Ensign S. V. Edwards,

kins' kites would serve adequately for
use on planes forced down so that

would not function satisfactorily.

plane use is being constructed and if
successful may be tried out on naval
planes, all of which are radio
equipped. 1t is the smallest of this
type ever developed.
