s''' most small or cheap sets can
lpa' ont local interferences.
m '% grld-leaks are not used on
cstaI detector sets Dut only on
,s's@uu.tube sets.
''s @s, large tuning-coil with wires
s a closely will give better results
" short coll or one with wires

' st yacuum-tube is about thirty
..'.s os efficient as a crystal detector.
' mat wave length has little to do
mn the distance you can receive.
M Thst 5000 ohm receivers will often

aeIlency.
That loading-coil Is not needed
M loose-coupler and variable-con-
jenser,
That II two or more crystal sets are
.sad on one aerial only one can be
rssd al one time and switch must
i uroyided to throw sets out and in.
That a loose coupler is better than
ituEingcoil.
That loose-coupler should be
paeed 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 phones.
That aerials and lead-ins should be
Sbunted 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
eadin is an advantage.
That aerlals and lead-ins should be
Insulated from everything else.
That aerials should be placed as
high as possible.
That when placing aerial near ele,
rated structures, wires, bridges, or
aeel buildings 1t should be placed at
Ight angles to them and as far away
S possible.
That strand, phosphor-bronze wire
the best for aerials, but ordinary
%. IA copper wire will do.
That continuous waves penetrate
1erything.
That the lead-in from aerial should
at end of aerial which is towards

Sh to hear.
That aerial does not have to be
riz0ntal
That for sending, many-wire
rial is far better than single wire.
That counterpoise is better than
,und particularly In sending.
That an indoor wire wiz serve for
aerial, but Is not so good.
That an iron bedstead or springfield

hat the best form Of receiving set
the regenerative set.
hat vacuum-tube or regenerative
may be amplified to almost any

hat an ordinary monograph horn

Increase the sounds somewhat
will act as a loud speaker.
