Feature 01

Full Control Head with Separated RF Deck

The IC-7760 consists of a separate control head and RF deck and uses a control cable for connecting between them. It increases the flexibility of the installation. A control cable (3 m, 9.8 ft) is supplied with 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.

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

Feature 02

Supports In-house Remote Operation Through a Home LAN Connection

The IC-7760 can be connected to the control 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 the shack but also from the living room, etc., as long as a LAN connection is available.

* 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

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.

Advanced RF Direct Sampling System

The IC-7760 adopts the RF direct sampling system, in which RF signals are directly converted to digital signals and the signals are processed 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 and control 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.

DIGI-SEL and Preamp

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 to take 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 unwanted out-of-band signals. This makes it possible that the preamp works together with DIGI-SEL.

A Total of 15-separated BPF

While the previous model covered HF bands with a 9-separated BPF

(Band Pass Filter)

In addition, by employing sharp filters specialized for each amateur band, 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

The DPD function corrects non-linear distortion at the final amplifier by applying inverse distortion in advance. A clean signal transmission is achieved 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*.

* DPD feedback cable OPC-2501 is required when using with the IC-PW2.

DPD OFF (Signal Received on the IC-7300) DPD ON (Signal Received on the IC-7300)

No spurious emission observed

100% Duty Cycle at 200 W Output

The IC-7760 uses a 450 W-class 65 V LDMOS-FET in the PA section, combined with a large heatsink and effective cooling system to achieve a generous 200 W full power full duty operation*. Continuous FT8 mode operation is also possible. Furthermore, modulation and frequency conversion are made through digital signal processing, the D/A converter directly outputs the transmit frequency, achieving the purest transmission C/N.

* 200 W and 1 hour continuous transmission with 100 V AC input (at ambient temperature 25˚C.)

Dual Display Control Head

The IC-7760 control head has main and sub dual displays. The displays are one 7-inch-wide main display (800

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 a band stacking register. The filter effect screen can display the IF filter passband width and IF filter shape superimposed on the IF filter passband signal. This function shows you visible images of twin PBTs, manual notch effects. The improved visibility of information enhances operability and ensures smoother operation.

Dual Spectrum Scope and Waterfall

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 to find 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 or mono output from both speakers.

MAIN/SUB Dual Speakers

PRESET FT8 Menu

Introduced with the IC-7300 as FT8 is actively used around the world in everyday operation as well as with DXpeditions. FT8 can be easily set up by simply selecting it from the [Preset] memory and all necessary items can be set at once. Moreover, when returning to the normal settings from FT8, simply select [Normal] memory for a smooth transition. In addition, up to 3 [Preset] memories can be written to preset SSTV as well as future new digital modes to be supported.

FT8 Mode Preset

Automatic Contest Serial Numbering

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 to ensure that the contest number is reliably copied.

Contest Serial Numbering Example

Audio Scope Flexibility

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.

SD Card Slot

An SD card slot is provided as an interface for data storage. In addition to voice recordings of outgoing and incoming calls, RTTY/PSK decode logs, captured images of the display, user settings, and firmware updates can be saved in the storage. Voice memories sent in Phone modes, and message memories sent in CW/RTTY/PSK modes, can also be stored. In addition, when an operator is replaced, the operator can simply load their preferred settings from the storage to immediately start operating.

SD Card Slot

Touch Screen and Multi-Dial Knob

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

Multi-Function Menu

The Audio Scope screen shows the transmit and received signal’s frequency components on the FFT scope, and its waveform components on the Oscilloscope. The Audio Scope makes it easy to monitor signal characteristics such as microphone compressor level, filter width, and notch filter. You can monitor received CW keying wave forms in the Oscilloscope.

I/Q Signal Output

External Display Connection

I/Q signals received by the IC-7760 can be output from a dedicated I/Q signal connector (USB on the RF deck) to a PC for digital output. Using the I/Q signals on the HDSDR*, you can listen to received signals, or display the spectrum scope on the PC. Used in combination with the CW Skimmer* or N1MM Logger+*, you can virtually decode all Morse signals in the operating band. This function is particularly useful for contesting and DX hunting, and effective callback during split operation.

* USB I/Q driver package can be downloaded from the Icom web site. HDSDR, CW Skimmer and N1MM Logger+ software are not supplied from Icom.
