A new innovative style of shack

__________________________________________________________________________________________

In today's connected world, the IC-7760 introduces a new connected system consisting of a remote control head and an RF bridge, connected to a commercially available control cable (LAN). This concept increases the flexibility of station installation, freeing up more desktop space by placing the RF bridge in an area closer to the antenna feed point. In addition to the direct connection function, the control head to the RF bridge, uses the home network to make any tabletop and a PC is not necessary!

Independent dual receiver

__________________________________________________________________________________________

The IC-7760 has independent MAIN/SUB receivers, from antenna to speaker, so that one receiver section has no effect on the other, providing simultaneous reception of two signals in different bands/devices with identical performance.

As with the IC-7851, the two spectrum scopes provide simultaneous display of the MAIN and SUB bands allowing the operator to see band change 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 nonlinear distortions that occur in the mixer stages during analog signal processing. Furthermore, by using DSP units in both the RF bridge and the control head, the IC-7760 can handle complex audio path switching thanks to various interface inputs and outputs, minimizing delay in a home LAN environment.

Block diagram overview

DIGI-SEL and Preamp

__________________________________________________________________________________________

The DIGI-SEL (Digital Pre-selector) is highly effective in rejecting strong out-of-band signals, such as from broadcast stations or multi-multi operation. In conventional models (such as the IC-7850/51 or IC-7610), the DIGI-SEL circuit was positioned immediately after the RF input (antenna) to prevent signal distortion from out-of-band interference. Even if the preamplifier was turned on, the noise figure (sensitivity of the receivers) could not be improved, since DIGI-SEL had insertion loss due to its narrow bandwidth. In the IC-7760, which is a direct sampling system, DIGI-SEL prevents overshoot (OVF) due to unwanted out-of-band signals rather than signal distortion, and the preamplifier uses the A/D converter to take full advantage of its dynamic range. When the preamplifier is turned on in the IC-7760, the preamplifier first improves the intended signal, and then DIGI-SEL filters out unwanted out-of-band signals. This makes it possible for the preamplifier to work in conjunction with DIGI-SEL.

A total of 15 separated BPF (Bandpass Filter)

While the previous model covered the HF bands with a BPF (Band Pass Filter), the IC-7760 uses a separate 11-band BPF in the HF bands.

Additionally, by using specialized sharp filters for each amateur band, the BPF efficiently attenuates out-of-band interfering signals in the RF stage and prevents overflow at the A/D converter.

100% Duty Cycle at 200W Output

The IC-7760 uses a 450W class 65V LDMOS-FET in the PA section, combined with a large heat sink and effective cooling system to achieve generous 200W* full-scale operation. Continuous FT8 mode operation is also possible. In addition, frequency modulation and conversion are performed through digital signal processing, the D/A converter directly outputs the transmission frequency, achieving the purest C/N transmission. Using 450W FETs in the 200W output, the PA achieves excellent IMD characteristics.

Dual display operation

Double exposure control head

The IC-7760 control head has dual main and sub displays. The displays are a 7-inch wide main display (800 x 480 pixels, WVGA) and a 2.4-inch sub display (320 x 240 pixels), and both displays are touch screens. The main display shows information necessary for operation, including the MAIN/SUB operating frequencies, the setting/time status of each function, as well as the spectrum scope, application scope, S-parameter, and RTTY/PSK31/63 decode messages.

Meter setup example

- 2.4 inch Sub Display

The 2.4-inch sub display can show filter settings, various meters and a band stacking register. The filter setting screen can display the IF filter passband width and IF filter shape superimposed on the IF filter passband signal. This function shows visible images of twin PBTs, manual notch effects. The improved visibility of information improves operability and ensures smoother operation.

Purpose of dual spectrum and waterfall

The Dual Spectrum Scope provides excellent scanning speed, resolution and a wide dynamic range of 100dB with combined FPGA, DSP and CPU processing for the main and sub bands. It can also monitor two different bands at the same time, useful for condition monitoring and during contests. The dual scopes can be displayed by the left-to-right or top-to-bottom layout, depending on the situation and needs. In continuous SCROLL mode, a wide bandwidth of more than 1MHz can be seen on the scope screen. The waterfall display shows changes in the frequency spectrum vertically, allowing the user to find a weak signal that is difficult to detect with the spectrum scope. Increase your QSO chances without missing the weak stations

Audio application flexibility

The Audio application screen displays the frequency components of the transmit and receive signal 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 the received CW keying waveforms on the oscilloscope.
