Armstrong Was First to Clearly
Understand Vacuum Tube Action
In Brief History of Radio, Professor Morecroft
Declares That De Forest, Inventor of the
Three-E Element Tube, Didn't Know Its Function

ly brought rich reward-he was
granted a patent, the validity of which
was recently confirmed, which gives to
him credit for being the first really to
understand the action of the three
electrode tube"
After detailing the work that led up
to the discovery of regeneration Pro-
fessor Morecroft continues:
"Amstrong's idea evidently enables
the vacuum tube which is being used
as detector to act also as generator of
the gh-frequency currents which
serve to produce the beats when the
continuous wave signals arrive. Not
cnly does the simple coupling idea of
Armstrong thus permit the audion to
act as receiver of continuous wave
tremely sensitive receiver at the same
time if the adjustments are carefully
carried out.
Fooled the Engineers
"The writer we'll remembers one
night, before Armstrong had published
his explanation of the action of the
oscillating tube, spent at Marconi's
then new station at Belmar, N. j..
Mr. Weagant, the chief engineer of
the American Marconi Company, and
Mr.. Sarnoff, at present manager of the
Radio Corporation, also were witnesses
of those early tests when Armstrong
showed us how his circuits could pick
up the continuous wave stations on
the Pacific Considerations with only a
few kilowatts of power.
"To hear the note of the station
changed at will by the turn of handle
on one of the boxes was severe puz-
zle for the Marconi engineer, especial
ly as Armstrong, like a proper in
ventor, had everything completely hid
cen in boxes, with the lids securely
screwed down. And nary a chance did
the chief engineer have to peep inside!
He would surely have been surprised
had he seen how simple the whole

Answer. Of course, cannot tell
you just exactly what results you will
be able to get with the super-regenera-
tive receiver, but I can say positively
that it will give you greater volume
from the nearby stations than you ever
experienced before. 1t must be under
ated on loop aerial, and your previ-
Gus good results were obtained from
the aerial that you were using. 2.
Fivewatt tubes give the best results
with the super-regenerative receiver.
These are power tubes, requiring 712
volts in the filament. 3. You cannot
make duo-lateral coils except with spe-
cial winding arrangements, and it will
be far cheaper for you to purchase the
coils than to make them. You can
obtain a 1,25o-surn coil for $3.50 and
the 1,5O0-turn coil for s3.70. 4. Any
coil wound on an insulating tube that
has a total inductance value Of ter
milli-henries will answer the purpose.
5. This type of choke coil is used in
regular telephone installations in re-
peater circuits and can be obtained
from houses dealing with such supplies
much easier than it can be constructed.

ances l would suggest Lavite as the

In brief history of radio develop
ment in radio Broadcast" Professor
J. H. Morecroft, after giving full credit
to DR.. Lee De Forest for the invention
of the three-element vacuum tube,
states that the inventor did not under
stand the functioning of his invention.
He then declares that E. H. Armstrong,
the young radio wizard of Columbia
University, was the first man fully to
understand the action of the tube. In
reviewing Armstrong; work the pro-
fessor says:
During 1911 and 1912 E. H. Arm
strong was studying for the degree of
electrical engineer at Columbia Uni
versity. He was not an especially bril-
liant student; in fact, in many Of his
courses he did rather poorly. The
writer knows because Armstrong was
one Of his students. The character
lstics of alternating current machinery
in general did not prove very enticing
to the young student, not because he
was lazy or Indifferent but because he
had hobby-and vision. He was
experimenting at his home with wire
less apparatus and trying to find out
how the three-electrode audion of Di
Forest worked. If De Forest confessed
in public that the action was too mys-
terious for him to explain, then Arm
strong would explain it for him!
Which he promised to do, and did very
shortly.
Talked of Nothing Else
after graduating, Armstrong con-
tinued at Columbia as assistant to the
writer in the radio laboratory. Later
he worked with Professor M. I. Pupin,
continuing his study of the three-elec-
trode tube. AS the writer looks back
to those days it seems undoubtedly
true that Armstrong understood the
action of the audion better than any
one else in the world. Day and night
he thought and talked of nothing else
but the audion; his devotion to this

Answer. l cannot state specifical
ly whether this particular tube can be
used successfully or not, but, as I un-
derstand that it is not critical in re-
gard to voltage, l should say that the
probability is that it is all right. 2. If
the tube will work on this circuit there
will be no necessity to make changes
in any of the values. 3. You can use
the condenser that you have men
toned, provided that you place the
fixed condenser parallel with it. /
would suggest that you use it in the
point marked C5 in the diagram. Anx
inductance coil with an open core that
has a total value of 10 milli-henries
will do for La. The duo-lateral 400
coil, for instance, will answer the
purpose. A. Use 4OO-turn duo-lateral
coil. 5. would suggest that you pur-
chase an iron-core choke coil of 100
milli-henries inductance. These coils
are used in telephone work for filter
purposes, and can be obtained from
any store dealing in telephone sup
plies. 6. Neither the sc" nor "B" bat

One method of changing capacity in

condensers III circuit. A second
method is to change the capacity of a

condenser movable in connection to
each other. When every part of the
