7.1.3 Receiving
In
Operate
mode,
the
tuner
power
supply
is
engaged,
and
the
tuner
is
prepared
to
receive
RF
Input
Drive
and
a
PTT
signal.
The
front
panel
meters
are
active,
band/frequency
data
is
processed,
and
the
tuning
solution
is
applied.
7.2 Tuning
There
are
two
modes
of
tuner
operation:
manual
and
automatic.
In
automatic
mode,
the
user
initiates
a
tune
operation
to
better
match
the
transmitter
and
the
antenna
system.
If
one
is
found,
the
match
solution
(L/C/L
values
and
frequency)
is
retained
in
tuner
non
‐
volatile
memory
and
automatically
used
when
the
frequency
of
the
transmit
slice
is
within
the
Match
Frequency
Range
(with
the
same
antenna
selected).
7.3 What is a successful match?
The
Tuner
Genius
XL
tries
different
combinations
of
capacitance
and
inductance
values
during
automatic
tuning
until
it
finds
a
combination
that
yields
an
SWR
less
than
the
set
maximum
for
the
frequency.
The
minimum
value
can
be
set
in
two
ways:
Press
the
center
knob
on
the
front
panel,
then
adjust
the
value
up
and
down.
Finally,
press
the
knob
again
to
save
the
result.
Adjust
the
minimal
value
in
the
Band
Configurator
screen.
See
section
8.3.5
,
Other
Tab
for
