BODY CAPACITY is
CAUSE OF ANNOYANCE
Methods by Which Its Effects
May Be Avoided - Possible
Reasons for Fading Signals.

Questions have been asked regard
Ing AN apparent phenomenon in tun-
Ing. The phenomenon In the case is
that just us the operator tuned In his
station and removed his hands from
the knob. the signals faded out; or II
may have been the other way around, |
and If the operator touches his set |
while listening TO concert, the sig |
mails will fade out.
This may be caused by body ca
pacity, and while some stations run !
into 1t quite frequently, others are not
bothered at all. Those living close to |
broadcasting station will never be
bothered with II as II only occurs with
q very close tuning. II Is explained
by the fact that the capacity of the
body coming in contact with the set,
which is very finely tuned, is thrown
out OF adjustment by the outside i'll
| duetance.
| There are several ways to guard
against it, and one of the best is TO
line the inside of the panel with tin
| foil or aluminium foil and ground 1t.
|
of the panel, It is cut away from all
binding posts, switch points or rods 10
prevent short circulting the set. There
Is one exception to this, aud that is the
ground binding post. If the tin foil is
pasted over this, 1t is. of course, auto
inatically grounded.
Shellac will do to make the foil ad
here to the panel, which will not have
to be dismantled to be lined. as the
foil can be placed on In small strips.
Another method of remedying the
effects {, body capacity is by using
metal dials on the variocoupler and
variometers; and in sets where the
variometers are very close to one an
other, moving them away will help.
Or In case II Is not desired to change
the set, placing nonmagnetic ma
terial between the variometers which
are close to each other and grounding
1t will remedy the i'll effects. For this
case, piece of glass such MS photog
raphers use, covered with tinfoil OF
one side. Is effective.
Fading signals have long been en-
countered by amateurs when receiving
long distance stations. In this case
the signals from goodly distance
away may be coming In loud AM
