Oscar (Artificial Satellite) Operation - Kenwood TS-700A Operating Manual

signal is emitted for a period of 0.5 to 1.0 second to start the
repeater station into operation.
Since the transceiver is factory adjusted for optimum
repeater operation, it can be readily used simply by plugging
in the tone oscillator element (optional accessory) to the
socket of the FM IF unit (X48-1140-20).
If your repeater station is such that the input frequency
is 146.34 MHz (FM), output frequency is 146.94 MHz (FM)
and the starting system is based on 1800 Hz tone burst
signals, first insert a 1800 Hz tone oscillator element into
the FM IF unit at the bottom of the chassis (see Fig. 13).

Next, set the switches and knobs as shown in Table 5.
If, at this time, the repeater station is already occupied by
anyone, you will be able to receive the communication
signals.
If the repeater station is unoccupied, you can transmit
signals for repeater operation. If tone burst signal is not re-
quired, set the TONE switch to OFF. To receive the input
frequency of the repeater station, set the REPEATER switch
to the REV position.
If the input frequency of a repeater station is higher
than its output frequency (this frequency relationship is
reversed in 147 MHz band), set the REPEATER switch to
REV and the repeater operation can be effected. If the
switch is set to NORMAL, the input signal of a repeater
station can be received.

4-9. OSCAR (Artificial Satellite)
OPERATION
At present, two amateur radio communication artificial
satellites (No. 6 and No. 7) are travelling along the orbit of
the earth. These satellites can also be used as your repeater
stations. In repeater operation using such satellites, your
TS-700A functions as a transmitter of 2m>10m "up-link"
repeater frequency or as a receiver of 70 cm>2m "'down-
link" repeater frequency. The link frequencies in this opera-
tion are given in Table 6 (page 20).
An example of 2m—10m repeater operation using TS-
700A and R-599 of our make is shown in Fig. 14 for your
reference.
Besides being used as shown in Fig. 14, the OSCAR
satellites also provide you with various applications such as
tracking of satellite orbit, use of beacon waves, etc., though
you need special knowledge on the manner of operation,
antenna installation and others which are somewhat
different from those on the general amateur radio com-
munication. With basic knowledge, you will be able to enjoy
repeater communication through the amateur artificial
satellites without difficulty. We suggest that you proceed
with "on the air" by referring to guide books available.
