and use
the
following
procedure to
mount the
BFO

Then
melt
a bead
of
solder
along
the
each
of the
four
corner
seams
in
the

2.
Slide
the
BFO
shield
onto the
two
long
screws
at
CP
and
CR as
shown
in
Part
B
of the
Detail.
Then use
two #6
lock-
washers
and
two
6-32
nuts to
secure the
shield.
Tighten
the
nuts
only
until
they
are snug.
(
)
Connect the
free
end of the
shielded
cable
coming
from
variable
capacitor Cl as
follows:
