difference in their strengths, adjust the CW sidetone level
with the CW MONI control, also located under the
access cover, until the strengths are the same.
WHEN ALIGNING THE FREQUENCY, DO NOT PUT
THE UNIT IN THE TRANSMIT MODE.
Be sure the T/R switch is in the Receive position, the VOX
switch is OFF, and that you do not touch the PTT switch
on the microphone.
5-5-5 SATELLITE COMMUNICTION
At present there are two active satellites for amatuer radio
use, though more are being planned. AMSAT OSCAR 7
5-5-6 RECEIVE ANTENNA TERMINALS
The RECEIVE ANT IN jack is connected to the input
terminal of the receiving section, and the RECEIVE ANT
OUT jack is connected to the antenna connector through
the internal T/R antenna switching circuit. These two jacks
are normally jumpered with a cable, but can be used with:
1. A receiving pre-amplifier
2. A separate receiver
3. Separate receiver and transmitter antennas.
If you wish to use a receiver pre-amplifier, connect it
between the receiver input and antenna output terminals.

was launched in November, 1974, and AMSAT OSCAR 8
was launched in March, 1978. Satellite communications
can be made by using an [C-211/211E for transmitting and
an !C-701 for receiving. For operation of the IC-211/211E
and the IC-701 and for frequency information, refer to the
chart below.
Since communication satellites are moving at very high
speeds, the down-link signals can be heard on a higher
frequency than the real frequency as a satellite approaches,
and on a lower frequency as it travels further away.
Further information on communicating through satellites
can be found in various amateur radio books and
periodicals.

lf a separate receiver is used, connect it to the receiver
antenna output terminal. For a separate receive antenna,
connect it to the receiver input terminal.
