That crystal detector set is never
as efficient as vacuum-tube set, no
matter what sort of equipment you
use.
That crystal detector set cannot
be satisfactorily amplified.
That most small or cheap sets can
not tune out local interferences.
That grid-leaks are not used on
crystal detector sets, but only on
vacuum-tube sets.
That large tuning-coil with wires
spaced closely will give better results
than short coil or one with wires
far apart.
That a variO-condenser and q loose
coupler gives finer tuning.
That vacuum-tube is about thirty
times as efficient as crystal detector.
That wave length has little to do
with the distance you can receive.
That 5000 ohm receivers will often
raise a cheap set from inefficiency to
excellency.
That a loading-coil is not needed
with loose-couplers and variable-con-
denser.
That If two or more crystal sets are
used on one aerial only one can be
used at one time and switch must
be provided to throw sets out and in.
That a Ioose-coupler is better than
q tuning-coil.
That a loose-coupler should be
placed between aerial and ground
That money saved in buying cheap
head phones or receivers Is really
thrown away and that a great deal
depends upon the raones.
That aerials and lead-ins should be
shunted across head-set.
That in setting up an aerial one long
wire is better than many shorter ones.
That the lead-in counts and long
lead-in is an advantage.
That aerials and lead-ins should be
insulated from everything else
That aerials should be placed rs
high as possible.
That when placing aerial near ele'
waited structures, wires bridges, or
steel buildings 1t should be placed at
right angles to them and as far away
as possible.
That strand, phosphor-bronze wire
is the best for aerials, but ordinary
No. IA copper wire will do.
That continuous waves penetrate
everything.
That the lead-in from aerial should
be at end Of aerial which is towards
the sending station you most often
wish to hear.
That aerial does not have to be
horizontal.
That for sending, many-wire
aerial Is far better than single wire.
That a counterpoise is better than
ground, particularly In sending.
That an indoor wire will serve for
an aerial, but is not so good.
That an iron bedstead or springfield
viii do for an aerial in case Of neces
sity.
That the simplest and cheapest
vacuum-tube receiving set Is better
than the best crystal set.
That the best form of receiving SET
Is the regenerative set.
That a vacuum-tube or regenerative
set may be amplified to almost any
extent.
That an ordinary photograph horn
attached to a head telephone receiver
will increase the sounds somewhat
and will act as loud speaker.
That variable-condenser helps fine
tuning.
That the filament battery Of g
vacuum-tube set may be dry bat
terry, but that 1t is more expensive
In the end than a storage battery.
That the Ultra Audion circuit has
the plate circuit led back to the honey
comb-coil and amounts to regenera
tive set.
That the best type of vacuum-bult
receiving set Is the regenerative witt
amplifiers.
That each step OF amplification re
.uires another tube.
That if there are too many turns
on the inductance they may be takeI
off to secure tuning.
That the distance you can receive
depends upon various climatic and
other conditions.
That the f1lament lighting does moi
always mean the set Is operating prom
erly.
That IL filament rheostat Is turned
on suddenly the filament may be
paralyzed and must be left to recuper
ate before 1t win glow.
That burning the filament too bright
ly merely wastes the filament anG
| shortens the life OF the tube withou
