4.11 OPERATION
WITH
A LINEAR
AMPLIFIER
Tune and load the TS-900
as described
in Sections 4.1
through 4.7 and adjust it for the selected mode. Connect
the appropriate
transceiver
relay control jack to the relay
control jack of the amplifier. See the instruction manual of
the amplifier to determine whether the linear requires the
RL MAKE
(normally
open
in receive) or the RL BREAK
(normally closed in receive) jack. Connect the ALC output
jack of the amplifier to the ALC INPUT jack of the TS-900.
The
ALC
feedback
of the amplifier should
prevent
the
TS-900
from
overdriving
the
linear for SSB
operation.
However,
for
tuning
be
careful
not
to
overdrive
the
amplifier. If necessary, tune the amplifier with the TS-900
in the TUN
mode to reduce power. Also, be careful not to
overdrive the amplifier for CW operation.
4.12 OPERATION
WITH
AN
EXTERNAL
RECEIVER
To operate the TS-900
with an external receiver, connect
the mute
connection
of the receiver (see the instruction
manual
of the receiver)
to the appropriate
relay contact
(RL
MAKE
or
RL
BREAK)
on
the
back
panel
of the
transceiver. The Kenwood
R-599 requires the RL MAKE
relay contact, however many other amateur receivers use a
break contact.
If the TS-900 is used with both an external receiver and a
linear
amplifier
which
require
the same
type
of relay
contact,
an external
relay may
be required. In this case
choose a relay that can be controlled by the opposite relay
jack of the transceiver.
You can use the TS-900 with the R-599, and use the VFO
in the R-599 for cross channel operation. To do this make
the connections described below.

:
In this configuration,
the relay contact described above is
not
a necessary
connection
since
the
mute
function
is
controlled
through
the interconnecting
cables. When
the
equipment is connected
in this manner, the VFO SELECT
switch of the R-599 controls the functions of each VFO.

To use the cross operating
feature
you must switch the

VFO switch to the RMT
position. To receive on
two
different
frequencies
at the
same
time,
you
must
disconnect
the
R-599
from
the TS-900
(or switch the
TS-900's VFO switch to the INT position).
4.13 CHANGING
THE
BAND
COVERAGE
The TS-900 is supplied for amateur band use. However, in
cases where the owner is willing to sacrifice one or more of
the
standard
frequency
ranges,
he
can
substitute
an
adjacent
special range
by changing the appropriate
high
frequency crystal.
The transition is easiest on the 10 meter band because there
are four frequency ranges. For special frequencies above or
below
the amateur
bands,
such
as MARS
frequencies
or
others,
you
can
achieve
coverage
by replacing
the
ap-
propriate
HF
crystal,
not
to
be
confused
with
fixed
frequency operation.
