Ten
Segment
LED
Bargraph
The
bargraph
provides
a
visual
indication
of
the
received
HF
signal.
The
end
segments,
labeled
MARK
and
SPACE,
blink
alternately
on
a
properly
tuned
RTTY/ASCIVAMTOR
or
Packet
signal.
In
CW
Mode
the
left
end
(MARK)
of
the
bargraph
illuminates
when
no
signal
is
present,
and
the
right
end
(SPACE)
lights
when
a
signal
is
detected.
In
addition,
when
your
PTT
line
is
being
keyed
to
transmit
on
the
HF
port,
the
LED
bargraph
will
be
blanked
out.
The
bargraph
may
be
used
to
tune
WEFAX
if
the
audio
from
the
WEFAX
signal
is
connected
to
the
HF
radio
port
as
well
as
the
VHF
port.
Between
picture
transmissions,
most
WEFAX
stations
transmit
a
SPACE
signal.
