The IC-R7000 is a sophisticated communications receiver designed
for a wide variety of users, covering HF, VHF, and UHF bands all in
one single, compact
unit. The IC-R7000 also comes installed with a
crystal converter
that makes Amateur radio reception possible in the
entire
1240 to 1300MHz frequency range.
The
IC-R7000 incorporates an AM mode, an FM mode using both
wide and narrow filters, and an SSB mode that offers both LSB and
USB selection, making a wide variety of reception possible.
A
total of 99 memory channels are available in the IC-R7000 for
convenient storage of both received frequencies and the reception
modes.
VFO operations are possible when using any memory
channel.
With the IC-R7000 you not only have normal tuning capability with
the front panel tuning control: you can also shift quickly to a
desired frequency
by using the keyboard to program frequency data.
In addition, tuning pitch can be selected between the following
frequencies: 100Hz, 1kHz, 5kHz, 10kHz, 12.5kHz, and 25kHz.
The IC-R7000 incorporates a total of six separate scanning functions
for easy access to a wide range of frequencies.
• PRIORITY SCAN eliminates the need for channel searching by
automatically monitoring programmed channels while you listen to
your main operating channel.
•
PROGRAMMED SCAN offers detailed coverage of a speci!ic fre-
quency range by repeatedly scanning it.
•SELECTED MEMORY SCAN allows you to continuously scan
your favorite programmed memory channels.
•SELECTED MODE MEMORY SCAN automatically monitors all
memories which contain programmed frequencies with a similar
mode.
• MEMORY CHANNEL SCAN repeatedly scans the entire 99-Channel
Memory in sequence.
• AUTO-WRITE MEMORY SCAN monitors the specified frequency
range contained in
PROGRAMMED SCAN and automatically
writes any incoming signals within that frequency range to Memory
Channels 80 through 99, the AUTO MEMORY WRITE AREA .
The VSC
(VOICE SCAN CONTROL) function in the IC-R7000
allows
you to skip all frequencies with inaudiable voice signals while
concentrating on those that are clear.
In addition to regular squelch capability, the IC-R7000 incorporates
an S-Meter Squelch function which squelches all incoming signals
stronger than the level indicated by the S-Meter. Incoming signals
less than the S-Meter reading will not be squelched.

Impedance for any antenna used with the IC-R7000 should be 50
ohms. If a coaxial feedline is used between the antenna and receiver,
it
should also have an impedance of 50 ohms.
To inhibit coaxial cable loss install a coaxial cable that is as thick as
possible since coaxial cable loss increases as
frequency increases. This
is particularly important with the IC-R7000 because of its ability to
receive high frequency signals at levels greater than 1200MHz.
Follow the procedure below for connecting cables with a coaxial
cable:
1) Slide the nut, washer, gasket and clamp over the coaxial cable and
cut the end of the cable evenly.
2) Cut and remove 15mm of the outer vinyl jacket, and fold the
braid back over the clamp. The clamp end should be flush with
the end of the vinyl jacket. Trim the bJaid ends evenly.
Cut and remove 6mm of the dielectric (center conductor insula-
tion).
3) Soft-solder the center conductor. Install cent.er conductor pin
and solder.
4) Carefully slide the plug body into place, aligning the center
conductor pin on the cable with the hole in the insulator inside
the plug body.
5) Complete the assembly by screwing the nut into the plug body.
To prevent accidents involving electricity and interference from
other machines, bury a commercially-available earthing rod or
copper plate in the ground and connect it to the rear panel
GROUND TERMINAL.
Make sure the thickest possible lead is used,and also be sure the lead
is as short as possible, covering the shortest distance from the
grounding rod to the GROUND TERMINAL.
CAUTION: It is extremely dangerous to use gas pipes or electri-
cal wiring for earthing purposes. Never ground your
receiver using these!
An external speaker can be connected to the IC-R7000 by using the
EXTERNAL SPEAKER JACK. For ideal audio clarity use an
external speaker with 8 ohms impedance. For your convenience a
connector plug comes with the IC-R7000.
When connected to an external speaker, the IC-R7000's internal
speaker will not operate.
Connect the external speaker to the supplied connector plug as
shown in the diagram.

ICOM has introduced a new remote control Local Area Network, the
ICOM COMMUNICATION INTERFACE-V (CI-V) SYSTEM using
the CSMA/CD (Carrier Sense Multiple Access with Collision
Detection) standard.
• A serial data bus carries all control data. Operation is possible
using an optional CT-17 LEVEL CONVERTER with a personal
computer equipped with an RS-232C serial port.
Up to four ICOM CI-V transceivers can be connected to a personal
computer via the CT-17.
Transmitters and receivers using the ICOM CI-V System exchange
serial information in the packet format. The contents of a data
packet can be changed by using connector pin J17 on the LOGIC
UNIT.

Press the POWER SWITCH to supply power to the IC-R7000. When
power
is supplied the displays and meter lamps are illuminated and
the receiver
is fully operational.
• The IC-R7000 has a backup memory function to ensure that no
frequency, receive mode, or memory information will be lost from
the FREQUENCY DISPLAY if power to the receiver is cut off
accidentally or prematurely.
•When power to the IC-R7000 is turned OFF, information illu-
minated on the FREQUENCY DISPLAY at that time will auto-
matically be preserved and stored.
• Prior to shipment from the factory, the I C- R7000 was programmed
with unspecified frequencies and receive modes in memory chan-
nels 1
through 10. Memory channels 11 through 99 are in blank
status.
1) To select
the appropriate mode you wish to receive in, press the
corresponding
MODE SWITCH on the front panel.
2) The selected mode will then be illuminated on the front panel
display.
NOTE: When any MODE SWITCH is pressed while a displayed
memory channel is in blank status, the FREQUENCY
DISPLAY will automatically indicate the lower fre-
quency limit (25MHz).
1) When the IC-R7000 is receiving, a hissing noise coming from the
speaker can be heard.
2)
To adjust the sound level of this noise, use the AF GAIN
CONTROL, slowly turning the control clockwise until a com-
fortable listening level is reached.

when setting new frequency.
2) Numbers move toward the left edge.
3) Press [ . ] .
The IC-R7000 has two squelch functions, Noise Squelch and Meter
Squelch.
Noise Squelch:
1) Turn the SQUELCH CONTROL clockwise until the "SIG"
indicator on the FREQUENCY DISPLAY goes out.
2) Received signal is now muted. Noise Squelch is effective in the
AM or FMn (6kHz, 15kHz) modes.
Meter Squelch:
1) The S-Meter can be set by continually turning the SQUELCH
CONTROL clockwise after the "SIG" indicator on the FRE-
QUENCY DISPLAY goes out.
2) Any received signals weaker than the level indicated by the
S-Meter on the METER will be squelched.

is squelched in this manner, the "SIG"
indicator goes out.
4) As long as the signal is not squelched, the "SIG" indicator >:Nill
remain illuminated.
1) Receive frequencies can be set by using the KEYBOARD or the
TUNING CONTROL.
See SECTION 5-3 FREQUENCY SETTING for additional
operating information.
