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 ˜exibility of your 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!

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.

Advanced RF Direct SampLing System

IC-7760 itengera RF mwachindunji 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.

Block Diagram Overview

DIGI-SEL ndi 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 imalepheretsa kusefukira (OVF) chifukwa cha ma siginecha osafunikira akunja m'malo mosokoneza ma siginecha, komansoamp amagwiritsa ntchito chosinthira cha A/D kuti atenge advan yonsetage of its dynamic range. When preamp imayatsidwa mu IC-7760, 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.

Block Diagram Overview

Chiwerengero cha 15-olekanitsa 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 amateur band, the BPF efficiently attenuates out-of-band interference signals in the RF stage, and prevents overflow at the A/D converter.

Ntchito ya DPD imagwiranso ntchito pakutulutsa kwa 1 kW kuphatikiza IC-PW2*.
* DPD feedback cable OPC-2501 is required when using with the IC-PW2.

100% Duty Cycle pa 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.)

Chojambulira chopangidwa ndi Automatic Antenna

The IC-7760 incorporates a mechanical relay type internal antenna tuner as a first for our 200 W models. It provides faster tuning than the conventional variable capacitor type. Once tuned, the matching information is automatically recalled the next time the frequency is selected, facilitating smooth band changes and multi-band operation. Antenna

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 × 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 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 ndi 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.

PRESET FT8 Menyu

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.

Nambala ya Seri ya Mpikisano Wokha

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.

Kusinthasintha kwa Audio Scope

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.

RC-28 kwa Knob Yachiwiri ya VFO

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 ndi 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.

I/Q Signal Output

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.
