rbe wear that is Just closing hsa
h,rn tbe most remarkable IN The
fistorv Of the radio art. Not only
Sss n ,esn the growth and develop
neat 81 ths public interest IN broad
..stiog. hut In the realms Of notable
,nvcntion Il has been the most pSoiinc
rsriod 1incs Msrconi sstounoed the
l~orlA twenty-slx years ago with the
announcement that he had comm Uni
Gated between two points WITHOUT the
aid OF connecting wirces.
So rapid did the Inventions ioiio"
.non each other that one Is left con

ssoitulate them IN their proper group

Ideal Future Receiver
From the point Of music reception
,, iii he the ideal broadcast receiver
- the future. It's merit, however
Jo,s mot remain restricted 20 music
,.cce,tion. In fact, that Is but incl
sa,tst For short wave wireless tele-
,.-a,bie reception a. viii undoubtedly
-svolufionjze future commercial com
.nunicatioa because OF It's reiaaiNSDIe Nse
ampiifying powers on extremely shoIs
waves below one hundred meteIs' ~
vill aid In taking away much OF tne
nFesent confusion in marine com
muDication, caused By the excessive
vtyslsss tsafie which now exists on
he seas. Yke surface Of super-regen-
erati-e possibilities has only been
scratched. ,t.,
IRE ,ther system Is the directional
Wirelsre communication apparatus oe-
veloped BIZ Guglielmo Mareoni and MS
sssistants. This system utilizes wave
length, Of one meter in length which
srs reflected IN direct line toward
no receiving station, just IN the same
manner as \ mirror reflects q beam
a light. Undreamed Of possibilities
lie In the future development OF this
.vstem. II makes radio lighthouses
an immediate possibility and VIII glFe
q measure Of secrecy 20 radio-phone
conversatlon which was not beleveo
possible q year ago.
Tbe two systems which have been
1oveloped M 70 q practical basis dur
.ng the year are, first, radio frequency
ampliheation as applied 70 short wave
reception, and second, the rehex sys-
tem, By means Of which a vacuum TUBE
cap be used for simultaneous amplin-
cation OF audible and suPer-audiele
freaueneies. The grave difhculties
which confronted engineers IN eonnee-
ion with amplifying the high fre-
ouencies involved in short wave radio
have been overcome by means OF care
July designed transformers.
Gigantic Tube Produced
On the transmitting side The de-
~slopnsnts have bssT equally phenom'
aaal l. rapid srNceSbion announce,
lneuta we're eds of the successful
production Of o io-kilowatt vacuum
.uAe. a 8O.kslovatt and finally 100
kiiowatt tuba These announcements
had scareesr been digested when .
statement va issued covering th'
details OF the development Of a rectify
nc tube OF The 1,000-kilowatt order
This tube Wilt have an important bear
ing upon the future transmission o.
mower along wires across the country
The iOQ-kilowatt vacuum tubes will un
doubtediy give Us trans-Atlantie radi'
telephone communication under con
ditions Approxim6ting commercial re
quirements during the coming year.
During the year We have seen th'
development OF a standard broadcast
INC station Of very high efficiency sn'
steady output, wherein the modulatiof
0f the voice currents has reached thl
point Of perfection. We have sseI
these brOadcasting stations success
fully connected up TO long distance
telephone lines so that events Of ma
tional importance could be hrosdcaste'
direct. Tho engineering problem
overcome in accomplishing this wer
considered in5urmountSble shor
time ago Among the notable event
20 broadcast were the worlds serie
baseball games, President Harding
address 10 the Congress IN Washington
he Philharmonic concerts IN Ne,
York and Georges Clemenceau's fare
we'll speech 20 America.
Among the new inventions Vhie
will have q bearing upon the immedi
ate future Of radio are two new type
Il receiving vacuum tubes-~the thin
bic tube, recently described IA thes
columns. BIZ means Of which the tub
can be operated direct from the light
re circuit without the aid Of an.
batteries whatsoever. and the sodium
anode tube, which ia an excellent dc
tect0r.
Another notable event during IN
rear wss the radio telephone tests be
tween the steamship America and III
experimental radio station az Des
Beach ~. !. In these tests the ordi
nary land line telephone system wa
connected direct 20 the radio tele
3hOnc and conversations carried ol
rom Offices IN the downtown soetioi
" New York and persons on a shil
IN mid-occan. II IS only matter o
months before this system win b
slzcod on commercial basis, 30 tina
any enc may take up their telepbon
rcceiycr and talk 10 q passenger sbosri
r. snip without having any radio sp
aaratus IN the home or once.
TIC most remarkable thing about "a
iual America tests vas that they wer'
conducted while the wireless operato'
aboard the ship vas using his wireless
telegraph equipment for the purpOt'
q Transmitting wireless kilograms. 4
act. the same serial was used for boil
purposes without any interference be
ing experienced.
The future IL very bright for radi'
Development
