A New Innovative Shack Style
Full Control Head with Separated RF Deck

High Power & Clean Transmit Signal for
A New Innovative Shack Style
In today’s connected world, the IC-7760 introduces a new connected system consisting of a control head and
RF deck, connected with a commercially available control (LAN) cable. This concept increases the flexibility ofyour station installation, making more space available on the desktop by placing the RF deck in an area closer
to the antenna feed point. In addition to the direct connect feature, control head to RF deck, utilize your home
network to make any tabletop your shack and a PC is not required!

Full Control Headwith Separated RF Deck

Supports In-house Remote Operation
Through a Home LAN Connection

The IC-7760 consists of a separate control head and RF deck anduses a control cable for connecting between them. It increases theflexibility of the installation. A control cable (3 m, 9.8 ft) is suppliedwith the radio, and a commercially available LAN cable* can be used
to install the RF deck in a more remote location. It enables the RF
deck to be placed in a rack or other location away from the station
desktop, providing a quiet shack environment away from the noise of
the fan used to dissipate the heat generated by the RF deck.

The IC-7760 can be connected to thecontrol head and RF deck through a wired
home LAN network*. This gives the user
even greater flexibility of the RF deck.
Because of its simple configuration that
does not require a PC, the control head of
the IC-7760 can be moved anywhere in
the house and operated not only from theshack but also from the living room, etc.,
as long as a LAN connection is available.

* LAN cable: Cat5e or higher.
Cable length: Maximum 100 m, 328 ft

In-house Remote Operation* Communication between the control head and the RF deck depends on the network
environment in which it is used.
Gigabit Ethernet is required. The control head can be used on a different network segment
than the RF deck such as over a network switch.

Feature 03

Dual, Independent Receivers

DIGI-SEL and Preamp

The IC-7760 has independent MAIN/SUB receivers, from the antenna to
the speaker, so that one receiver section has no effect on the other,
providing simultaneous reception of two signals in different bands/modes with identical performance. As with the IC-7851, dual spectrum
scopes provide simultaneous display of the MAIN and SUB bands
allowing the operator to see the changing band conditions.

The DIGI-SEL (Digital Pre-selector) is highly effective in rejecting
out-of-band strong signals such as from broadcasting stations or
multi-multi operation. In conventional models (such as IC-7850/51 or
IC-7610), the DIGI-SEL circuit was located soon after the RF input(antenna) to prevent signal distortion by out-of-band interference. Even
if the preamp was turned ON, the noise figure (receiver sensitivity)
could not be improved, as DIGI-SEL had an insertion loss due to its
narrow bandwidth. In the IC-7760, which is a direct sampling system,
DIGI-SEL prevents overflow (OVF) due to unwanted out-of-band signals
rather than signal distortion, and the preamp uses the A/D converter totake full advantage of its dynamic range. When preamp is turned ON in
the IC-7760, the preamp enhances the intended signal first, then
DIGI-SEL filters out

Low Distortion DIGI-SEL: ON / PREAMP: OFF

Advanced RF Direct Sampling System
The IC-7760 adopts the RF direct samplingsystem, in which RF signals are directly
converted to digital signals and the signals areprocessed by an FPGA (Field Programmable
Gate Array). This system avoids non-linear
distortions that occur in mixer stages during
the analog signal processing. In addition, by
employing DSP units in both the RF deck andcontrol head, the IC-7760 is able to handle
complex audio path switching due to various
interface inputs and outputs, while minimizing
delay in a home LAN environment.

A Total of 15-separated BPF
While the previous model covered HF bands with a 9-separated BPF(Band Pass Filter), the IC-7760 uses an 11-separated BPF in HF bands.
In addition, by employing sharp filters specialized for each amateurband, the BPF efficiently attenuates out-of-band interference signals in
the RF stage, and prevents overflow at the A/D converter.

DPD (Digital Pre-Distortion) Technology

Dual Display Control HeadThe DPD function corrects non-linear distortion at the final amplifier byapplying inverse distortion in advance. A clean signal transmission isachieved while providing 200 W of high output power at the same time.
The DPD function also works at the 1 kW output in combination with
the IC-PW2*.

The IC-7760 control head has main and sub dual displays. The displays
are one 7-inch-wide main display (800 × 480 pixels, WVGA) and one
2.4-inch sub display (320 × 240 pixels) and both displays are touch
screens. The main display shows information necessary for operation,
including MAIN/SUB operating frequencies, and setting/ operating
status of each function.
The 2.4-inch, sub-display, can show the filter effect, various meters, and aband stacking register. The filter
effect screen can display the IF
filter passband width and IF filter
shape superimposed on the IF
filter passband signal. Thisfunction shows you visible imagesof twin PBTs, manual notch
effects. The improved visibility of
information enhances operability

The dual Spectrum Scope provides excellent sweep speed, resolution,
and a wide dynamic range of 100 dB with FPGA, DSP and CPU
combined processing for main and sub bands. It can also monitor two
different bands at the same time, which is useful for monitoring conditions
and during contests. In the Continuous SCROLL mode, a wide bandwidth
exceeding 1 MHz can be seen on the scope screen. The waterfall display
shows changes in the frequency spectrum vertically, enabling the user tofind a weak signal that is difficult to detect with the spectrum scope.
Increases QSO possibilities without missing weak DX stations.

Dual Speakers

RC-28 for a Second VFO Knob

The IC-7760 is also equipped with dual
speakers. By separating the MAIN/SUB
audio into left and right speakers,
respectively, distinguishing the audio during
Dualwatch operation is improved.
MAIN/SUB audio can be set for stereo ormono output from both speakers.

By connecting the optional RC-28 via
USB connection, the SUB band tuning of
the IC-7760 can be conveniently
operated with your fingertips. MAIN/SUB
switching buttons can be assigned to the
F-1 and F-2 buttons on the RC-28 and it
can operate as the main dial for both
MAIN and SUB bands.

Touch Screen and Multi-Dial Knob

This function is powerful in CW and RTTY
contests. Each time the pre-programmed
memory is transmitted, the serial number is
automatically counted from 001. The serial
number can be set in multiple locations toensure that the contest number is reliably
copied.

The combination of the touch screen andthe multi-dial knob offers easy access tovarious settings. When the multi-dial knob ispressed, menu items appear on the rightside of the display near the dial. Touch thatmenu to select an item, then turn themulti-dial knob to adjust the level, providing
much faster access to various functions
such as RF power, microphone gain,
DIGI-SEL, and notch functions.
