as efficient as yacuum-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 interference.
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 coll or one with wires
far apart.
That a vario-condenser and = loose
coupler gives finer tuning.
That a vacuum-tube is about thirty
times as efficient as a crystal deiector
That wave length has little 10 do
with the distance you can receive.
That 1900 ohm receivers will often
raise cheap set from inefficiency 70
excellency.
That s loading-coil is not needed
with a loose-coupler and variable-con-
denser.
That n two or more crystal sets are
used on one aerial only one can he
used at one time and switch must
be provided 10 throw sets ont and IN
That a loose-coupler is better than
q tuning-coll.
That a loose coupler should be
placed between aerial and ground.
That money saved I'm buying cheap
head phones or receivers Is really
thrown away and that a great deal
depends upon the phones.
That aerials AMI 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-'n counts and n long
lead-in Is an advantage.
That aerials and lead-ins should be
Insulated from everything else.
That aerials should be placed as
high SIS possible.
That when placing aerial near ele,
waited structures wires. bridges. or
steel buildings IL should be placed at
right angles TO them and as far away
"a possible.
That strand. phosphor-bronze wire
is the best for aerials, but ordinary
No. II copper wire viii 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 20 hear.
That aerial doSs not have TO be
horizontal.
That for sending. q many-wire
aerial is far better than a 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
| will 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
r. the regenerative set.
That a vacuum-tube or regenerative
set may be ampliied TO almost any
extent.
That an ordinary photograph horn
attached to head telephone receiver
| will Increase the sounds somewhat
and will act as a loud speaker.
That a variable-condenser helps fine
| tuning.
That the filament battery of q
vacuum-tube set may be a dry bat
| terry, but that II is more expensive
In the end than a storage battery.
That the Ultra Audlon circuit has
the plate circuit led back To the honey.
comb-coil and amounts TO regeners
| tive set.
That the best type Of vacuum-bult
| receiving set Is the regenerative with
| ampllfiers.
That each step OF application 70
| quires another tube.
That If there are too many turns
on the inductance they may be taken
of TO secure tuning.
That the distance you can receive
depends upon various climatic and
other conditions
That the filament lighting does moi
always mean the set is operating pron
| eriy.
That II filament rheostat Is turned
on suddenly the filament may be
paralyzed and must be left to recuper
ate before IL will glow
That burning the filament too bright
~ merely wastes the fllament and
shortens the life of the tube withou,
