Modification
NOTE:
The
Linear
Amplifier
has
a
built
in
antenna
relay,
therefore,
the

This
jack
will
be
used
for
the
external
ALC
output,
Refer
to
Figure
3A
and
the
following
instructions
for
this
modification,
(
)
Mount
the
1-lug
terminal
strip,
supplied
with
the
Linear
Amplifier,
on
one
mounting
screw
of
the
RCVR
jack
as
shown,
