Outstanding HF Experience Right Here…
Icom’s mid class HF transceivers evolved especially with the IC-756, IC756PRO and IC-7600, and were technology leaders in amateur radio. Even
the IC-7610 inherits the genealogy of Icom’s mid class transceivers, but
its development concept, circuitry, adopted devices, and performance are
innovative. The IC-7610 has superior performance and features far beyond
the perception of current mid class HF transceivers. The performance and
features are realized by fusing the proficient digital and analog technologies
of the successive flag ship transceivers, and refined RF direct sampling
technologies developed in the IC-7300.
The Reciprocal Mixing Dynamic Range (RMDR) characteristics show nearby
signal rejection receiver performance, and the IC-7610’s RMDR is 110 dB at 2
kHz separation (Receive frequency: 14.2 MHz, Mode: CW, BW: 500 Hz). This
is an incredible performance for a mid-class transceiver, and it is close to that
of our flagship IC-7851. The IC-7610 also has several flagship grade features,
such as dual, identical, independent receivers and dual independent DIGI-SEL
units for the Main and Sub bands. In addition, dual high-resolution and high
sweep speed real-time spectrum scopes are built in.
The IC-7610 has a high resolution 7-inch wide (diagonal) touch screen LCD,
and a server PC function for remote shack operation. In addition, a variety of
external connectors, such as an external display connector, LAN port, USB
ports for remote operation, are built into the IC-7610. Totally, the IC-7610
gives you not only flagship grade performance and features, but also flagship
grade operability and scalability.
You can feel the flagship grade performance visually, audibly, and tactically.
And you will have an advantage in contests and DX hunting.

Major Features
Designs and technologies inherited from the IC-7851
Two completely independent receivers
with identical performance
The IC-7610 has dual, completely independent, equally
high performance receiver circuits for the Main and Sub
bands. The circuits are in the stages from the antenna
through the Field Programmable Gate Array, (FPGA), as
illustrated in Figure 02-01 below.
The concept of the IC-7610 is the same as our flagship
model IC-7851, even though there is a difference in the RF
direct sampling system and the double superheterodyne
system. Of course the receiver circuits are designed with
enough isolation to not have any effect on each other.
The received signal is demodulated in the FPGA.
However, the demodulation is done in independent
demodulators inside the FPGA. The AF amplifier stages
are also independent for the Main and Sub bands.
The IC-7610 has two antenna connectors. The
DUALWATCH operation is possible by selecting different
frequency coverage antennas to receive signals, receiving a
signal with the diversity method, and connecting horizontal
and vertical antennas.
This high performance flagship grade DUALWATCH
function enables searching for a signal on the Sub band,
while communicating on the Main band.
Independent DIGI-SEL (Preselector)
circuits for the Main and Sub bands
The IC-7610 is the first in the mid class HF amateur
radio market to employ automatic preselector circuits as
standard.
A preselector is a type of RF filter with sharp skirt
characteristics. Icom decided that the preselector is a
necessary and useful tool in a mid class transceiver,
even though up until now, the preselector had only been
incorporated into our flagship grade transceivers.
The IC-7610’s independent preselector circuits are built
into both the Main and Sub bands.
DUALWATCH operation on different
bands and in different modes
In the IC-7600, the same receiver circuits are used in
both the Main and Sub bands, except the mixer circuit.
Therefore, DUALWATCH operation has some limitations
in the same band and mode. However, the IC-7610 enables
DUALWATCH operation in different bands and modes,
because completely independent and identical performance
receiver circuits are employed.

Major Features
Benefits of the latest digital technologies
RF direct sampling system
The RF direct sampling system is employed in the IC-7300,
ahead of its competitors. The RF direct sampling system
has been improved and is used in the IC-7610.
The RF direct sampling system directly converts the
received RF signals into digital signals, and batch complex
signal processing is done in the Field Programmable Gate
Array (FPGA). There is no nonlinear distortion, which
occurs in a mixer circuit of the superheterodyne system
receiver, because there is no analog mixer.
In the RF direct sampling system, received signal
detection and demodulation, and transmit signals are
directly generated in the FPGA. So the purity of the signal
is very high, and it’s a large contributor to the excellent
characteristics in transmit and receive.
Top class RMDR 110 dB*
The Reciprocal Mixing Dynamic Range (RMDR) is used
as one of the standards representing receiver performance.
The RMDR of the IC-7610 is 110 dB*, approaching the 116
dB* of our IC-7851 flagship model.
The RMDR is a standard that shows how much the
receive sensitivity deteriorates due to blocking from strong
adjacent signals. A larger RMDR value means that the
blocking effect is less. In general, a lower LO phase noise
provides better RMDR characteristics.
It is an outstanding improvement of approximately 30
dB in the IC-7610, as the IC-7600 RMDR is approximately
80 dB. You can clearly see this difference, not only in a
contest, but also in any operating situation.
*Sample configuration ( 2 kHz offset, Rx frequency: 14.200 MHz, Mode:
CW, BW: 500 Hz)
Excellent transmit phase noise characteristics
A transmit signal is directly generated by the FPGA,
as previously described. So, a signal is not generated by
mixing several LO signals, like in the superheterodyne
system.
The purity of a transmit signal, that is generated at the
Digital Analog Converter (DAC) using the Digital Up
Conversion (DUC) method is extremely high, and this
provides improved transmit phase noise characteristics.

Major Features
Further evolution of the spectrum scope
Dual spectrum scopes with amazing
dynamic range
The high-spec spectrum scope that is in our flagship IC7851, and its know-how, are also built into the IC-7300.
The spectrum scope is further improved and incorporated
in the IC-7610.
The excellent 100 dB dynamic range of the scope display
is achieved by cooperative processing with the FPGA and
CPU software. Off course, the sweep speed and resolution
are also improved to the level of our flagship model. This
spectrum scope can also be used during DUALWATCH
operation to show both Main and Sub bands conditions,
and its performance is the same in single band operation.

High resolution waterfall
The waterfall can display received signal history in
moving time, and shows weak signals that are difficult to
discriminate with only the spectrum scope. The waterfall
is simultaneously displayed with the spectrum scope, so
you can easily see the details of the band condition and
clear frequencies. When you select the expanded screen, a
longer history can be displayed on the waterfall.
The waterfall is one of the features that increases the
possibility to communicate using the optimized IC-7610
receiver performance, without missing weak signals from
DX stations.
Audio scope for flexible utilization
The audio scope displays an FFT scope and an oscilloscope,
for both transmit and receive audio. The received signal’s
modulation characteristics, filter width and notch
characteristics, and the microphone compression effect of
your transmit audio can be displayed.
While receiving, audio of either the Main or Sub band can
be displayed.

Major Features
Various functions and connectors built in
Large 7-inch touch panel LCD
The IC-7610 has a large and wide 7-inch LCD. It is 120%
larger compared with the one for the previous model, the IC-
7600. The display resolution also is much better, increased
from 400 × 240 pixels to 800 × 480 pixels.
With the tremendous increase in display size and
resolution, the LCD can display a variety of information
on the transceiver's condition. The spectrum scope on the
real time display gives you a higher accuracy of the band
conditions. To get an idea of the spectrum scope quality,
for example, when you look at a signal spectrum on the
previous LCD, you may see it like an unfocused mountain.
However, when you look at it, you can clearly find that it is
a large number of signals of stations calling in a pile up.
Fig 02-05 Comparison of LCDs
The LCD built into the IC-7610 is also a touch screen.
This gives you intuitively action under various operations
so that it makes settings easier.
Two USB connectors on the front panel
Two USB connectors are basically to connect
a keyboard for PSK or RTTY operation.
In addition, the connectors on the IC-7610
can be used for mouse operations on the
spectrum scope. The mouse operation enables
you to quickly select a signal on the spectrum scope.
For this reason, two USB connectors enable you to use
to simultaneously use a keyboard and a mouse. You can
also connect an optional RC-28 Remote encoder to this
connector and use it as your sub-dial. When you insert a
USB memory stick to a connector, you can save the memory
contents, various transceiver settings, or screen capture
data of the IC-7610.
Built-in SD card slot
You can save not only memory
channel contents and a wide
variety of transceiver settings, but
also a QSO log for RTTY or PSK
operations, and screen capture data, on the SD card memory.
For example, when your group participates to a contest as
a multi-operator class, an individual operator can quickly
start QSOing with their favorite transceiver settings
saved on the SD card memory, if each operator saves their
favorite transceiver settings in advance. You do not have to
waste time manually resetting the transceiver each time
the operator changes.
It is convenient to reuse the QSO record data, QSO log, or
the screen capture, if you store the data on your PC.
Easy operation with the Multi-dial
The IC-7610 has the unique Multi-dial, the
same as the one on the popular IC-7300. This
dial makes not only a simple panel layout,
without installing individual function knobs,
but also makes the operation easier with the
addition of the touch operation.

You can also change the settings of the following functions
assigned to the multi-function keys with the Multi-dial.
● VOX gain ● ANTI VOX gain ● VOX delay time
● VOX voice delay time ● COMP level
● TX bandwidth ● Attenuation level
● Break-in delay time
TX voice digital voice memory
The recording time limited to a maximum 30 seconds
for only the receive signal has been improved to record
unlimited transmit voice as well as receive voice*.
In addition, the number of voice memory channel is increased
from 4 channels to 8 channels. Recording time is also increased
from 99 seconds to 200 seconds in total for the 8 channels.
* If the voice data file reaches 2 GB, the transceiver automatically makes
a new file on the SD card to continue recording.

Major Features
Simple remote operation with the server
PC function and LAN port
The IC-7610 has a server PC function and a
LAN port built in. The server PC function is
convenient for building your remote control
operation through a network using the RS-BA1
optional remote software. You do not need to connect a server
PC to the base station. This function and the LAN port make
it easier to set up the connections and networking.
Fig. 02-06 Connection through a LAN
Two USB ports for external control
The IC-7610 has two USB ports (USB-B
type) to control the transceiver from
external devices. One is used to control
the transceiver with a PC through a CI-V
(Communication Interface-V) commands and application
software, such as RTTY/PSK/JT-65 software. QSO logging
software installed on your PC can also be used through
the port.
The other one is for a wideband digital IQ signal output,
and connects to your PC.
* The IQ signal output will be supported by a future firmware update. (as
of September 2017)
Advanced operations are possible with a variety of I/O terminals
External display terminal built in
An external display terminal is
built in. The terminal uses the
DVI-D (Digital Visual Interface)
format, and you do not need
settings for the resolution or synchronized frequency on the
transceiver. You can monitor the transceiver condition and
the receiver condition changes moment to moment with a
large external display, the same as the displayed on the
front panel display.
BNC connectors for the RX antenna lines
We listened to the voices of
contesters, too. We know that their
operating environment in a contest
is always severe and abnormal
because of heavy QRM among high
power stations that participate the contest. You can install
a filter between the RX-ANT connectors to meet your
operating needs. This is very useful when using a filter to
eliminate unwanted signals. You do not need to be concerned
with RF loss on the transmission line by installing the filter
on the reception line. As the connectors are installed on the
receive line, you can use them for other purposes.
The connectors are reliable BNC type and have better
electrical specifications than previously used RCA jacks.
Reference signal input terminal built in
The IC-7610 has a 10 MHz reference signal
input terminal installed on the rear panel.
The terminal is reliable 50 Ω BNC connector,
and is used to process internal signals on the
circuits. You can switch a reference signal
between the internal and the external signals.
The reference signal is one of the important signals to generate
transmit and receive signals. It is not actually necessary to
apply the reference signal to the terminal externally. However,
you can have a more precise frequency if you apply the accurate
reference signals externally from a device that has a more
accurate signal. If you have several Icom transceivers that have
a reference signal input terminal, and if you apply the reference
signal from one source signal generator, all your transceivers
will have the same frequency accuracy.
Two independent external speaker jacks
The IC-7610 has the DUALWATCH
function that was introduced in only
the top class transceivers up until now.
You can receive two independent signals
simultaneously, in different modes as well as on different bands
with the DUALWATCH function. Those two different signals
are independently output from the external speaker jacks.
When you place two external speakers on the right and
left sides of the transceiver, you can listen to only the Main
or the Sub band audio through the jacks.
