FOREWORD
Previous view
Thank you for choosing the IC-7850. The IC-7850 has many built-in high technology circuitry and unique functions, such as the Dualwatch on the Main and
Sub bands, a high speed spectrum scope scan, a high-resolution waterfall
screen, and many other outstanding features.
The internal frequency signals in a radio utilizing a PLL are not always sufficiently pure. This results in a considerable number of unwanted spurious
components, called phase noise, in its frequency spectrum. We focused intensively in drastically reducing the phase noise of LO (Local Oscillator) because
the phase noise degrades the interference rejection and noise characteristics
of the receiver. As a result, we succeeded in developing an LO with high purity outputs so that results in an RMDR (Reciprocal Mixing Dynamic Range)
of 101dB with newly developed 1.2kHz Optimum Roofing Filter. Currently no
competitors have been able to achieve this extremely high result performance.
We believe we would not have been able to exceed the standard specifications without our full focus on LO purity.
In addition, Icom that has chosen to base the IC-7850 on an up-conversion,
double super-heterodyne receiver design, which has many advantages over
traditional receiver designs.
We are proud to have developed the IC-7850 for your amateur radio activities,
and hope it brings you years of enjoyable operation.
Please read this instruction manual thoroughly before using the IC-7850.

PRECAUTIONS
Previous viewPrevious view
R DANGER HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
R WARNING! NEVER operate the transceiver
with a headset or other audio accessories at high
volume levels. The continuous high volume operation
may cause a ringing in your ears. If you experience
the ringing, reduce the volume level or discontinue
use.
R WARNING! NEVER operate or touch the
transceiver with wet hands. This may result in an electric shock or damage to the transceiver.
R WARNING! NEVER let metal, wire or other ob-
jects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
R WARNING! Immediately turn the transceiver
power OFF and remove the power cable if it emits an
abnormal odor, sound or smoke. Contact your Icom
dealer or distributor for advice.
CAUTION: NEVER put the transceiver in any un-
stable place (such as on a slanted surface or vibrated
place). This may cause injury and/or damage to the
transceiver.
CAUTION: NEVER put the transceiver’s rear
panel side down after lifting up the transceiver by
holding rack mounting handle. This may scratch the
surface of the place or damage the connectors on the
transceiver’s rear panel.
CAUTION: NEVER change the internal settings
of the transceiver. This may reduce transceiver performance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might damage the expensive final devices.
The transceiver warranty does not cover any problems caused by unauthorized internal adjustment.
CAUTION: NEVER block any cooling vents on the
top, rear or bottom of the transceiver.
CAUTION: NEVER expose the transceiver to rain,
snow or any liquids.
CAUTION: The transceiver weighs approximately
23.5 kg (52 lb). Always have two people available to
carry, lift or turn over the transceiver.
CAUTION: The line-voltage receptacle must be
near the transceiver and must be easily accessible.
DO NOT use extension cords.
DO NOT
cohol when cleaning, as they can damage the transceiver’s surfaces.
DO NOT
ally desire to transmit.
use harsh solvents such as benzine or al-
push the PTT switch when you don’t actu-
DO NOT use or store the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOT place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT place the transceiver against walls or
putting anything on top of the transceiver. This may
overheat the transceiver.
Always place unit in a secure place to avoid inadvertent use by children.
BE CAREFUL! If you use a linear amplifier, set the
transceiver’s RF output power to less than the linear
amplifier’s maximum input level, otherwise, the linear
amplifier will be damaged.
BE CAREFUL!
cover when transmitting continuously for long periods
of time. The top cover may be hot.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7850 may
damage the transceiver or microphone.
The LCD display may have cosmetic imperfections
that appear as small dark or light spots. This is not a
malfunction or defect, but a normal characteristic of
LCD displays.
During maritime mobile operation, keep the transceiver and microphone as far away as possible from
the magnetic navigation compass to prevent erroneous indications.
NEVER touch the transceiver top
CAUTION: NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
Turn [I/O] switch (on the rear panel) OFF and/or disconnect the AC power cable from the AC outlet when
you will not use the transceiver for long period of time.

• The [DIGI-SEL] indicator lights white when the preselector is in use.
&4 PASSBAND TUNING CONTROLS [TWIN PBT]
(p. 7-5)
Adjusts the receiver’s IF filter “passband width” us-
ing the DSP.
• The passband width and shift frequency are displayed in
the Multi-function display.
•
Hold down [PBT CLEAR] for 1 second to clear the PBT
settings.
• The adjustment range is half of the selected lter passband width, and the value is adjustable in 25 Hz steps
for the SSB/CW/RTTY/PSK modes, and 100 Hz steps
for the AM mode.
What is the PBT control?
The PBT function electronically modifies the IF passband
width to reject interference. This transceiver uses the DSP
circuit for the PBT function.
&5 RIT/∂TX CONTROL [RIT/∂TX] (pp. 7-3, 8-5)
Shifts the receive and/or transmit frequency without
changing the transmit and/or receive frequency.
• Rotate the control clockwise to increase the frequency,
or rotate the control counterclockwise to decrease the
frequency. The RIT or ∂TX functions must be ON.
• The shift frequency range is ±9.999 kHz in 1 Hz steps (or
±9.99 kHz in 10 Hz steps).

Unpacking
After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equipment included with the IC-7850, see ‘Supplied accessories’ on page vii of this manual.
Selecting a location
Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna elements, radios and other electromagnetic sources.
The base of the transceiver has optional angled front
feet for desktop use. If desired, place the optional feet
over the standard feet. Be sure the angle of the bottom
of the feet are such that the front of the transceiver is
angled up, and is stable.
Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the [GND] terminal and ground as short as
possible.
R WARNING! NEVER connect the [GND] ter-
minal to a gas or electric pipe, since the connection
could cause an explosion or electric shock.
Attaching the rack mounting handle
Remove the two screws from each side of the front
panel and the one screw from each side of the side
panel. Attach the rack mounting handles to the sides
of the transceiver using only the supplied accessory
screws.
CAUTION: NEVER put the transceiver’s rearpanel
side down after lifting up the transceiver by holding
rack mounting handle. This may scratch the surface
of the place or damage the connectors on the transceiver’s rear panel.

For radio communications, the antenna is of critical
importance, along with the output power and receiver
sensitivity. Select antennas, such as a well-matched
50 Ω antenna, and feedline.
If you use only one antenna, connect it to the [ANT1]
connector.
CAUTION: Protect your transceiver from light-
ning by using a lightning arrestor.
Main dial attachment
The Main Dial is shipped unattached to the transceiver
to prevent possible damage to the dial shaft or rotary
encoder during shipping. Please attach the dial as described below.
q Slide the dial brake adjustment to the right posi-
tion.
• The dial brakes move inward as shown.
w Insert the Main Dial set-screw into the screw hole of
the main dial, then tighten the screw until the screw
extends into the shaft hole out slightly using supplied hexagonal wrench (2 mm).
• Be careful that the screw does not extend out more than
1 mm (0.04 in).
e Attach the main dial as illustrated.
• Be careful to match the correct orientation of the flat
face of the shaft and the screw hole of the dial knob.
r Tighten the screw using supplied hexagonal wrench
as illustrated.
t Install the rubber cover to the Main Dial little by lit-
tle.
• Be careful to match the correct position of the convex
part of the rubber cover and the concave part of the dial
knob.
• Never install the rubber cover on the Main Dial by force.
This may cause damage to the dial shaft or rotary encoder.

R WARNING!
Set the transceiver output power and linear amplifier ALC output level referring to the linear amplifier
instruction manual.
The ALC input level must be in the range 0 V to
–4 V. The transceiver does not accept positive volt-
age. Non-matched ALC and RF power settings
could cause a fire or damage the linear amplifier.
The maximum control level of [RELAY] jack
is 16 V/0.5 A DC with the initial setting, and
250 V/200 mA with the “MOS-FET” setting (see p.
20-4 for details). Use an external relay unit when
your non-Icom linear amplifier requires a control
voltage and/or current greater than specified.
When using a linear amplifier that has a time delay
between receiving and transmitting, a high SWR
might cause the linear amplifier to malfunction. To
prevent this, slow the TX Delay the “TX Delay (HF),
(50M)” settings in the Others Set mode. (p. 15-13)

BASIC OPERATION
About the 5 MHz frequency band operation (USA version only)
Operation on the 5 MHz frequency band is allowed on
5 discrete frequencies and must adhere to the following:
• The USB, USB Data, CW, and PSK modes.
• Maximum of 100 watts ERP (Effective Radiated Power)
• 2.8 kHz bandwidth (maximum)
It is your responsibility to set all controls so that transmission in this frequency band meets the stringent
conditions under which amateur operations may use
these frequencies.
To assist you in operating within the rules specified
by the FCC, transmission is illegal on any frequencies other than the five shown in the tables below.
• For the USB and USB Data modes
The FCC specifies center frequencies on the 5 MHz
frequency band. However, the transceiver displays
carrier frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center frequency.
NOTE: We recommend that you store these frequencies, modes and filter settings into memory
channels, for easy recall.

DCW side tone function
When the transceiver is in standby (and the break-in
function is OFF— p. 8-4) you can listen to the CW side
tone without actually transmitting.
This allows you to match your transmit frequency exactly to another station’s by matching the audio tone.
You can also use the CW side tone (be sure to turn
OFF break-in!) to practice CW sending. The CW side
tone level can be adjusted in the Level set mode (p.
15-5).
