IC-7760

The transceiver consists of a separate remote control head and RF deck and uses a LAN cable for connecting between them. It increases the flexibility of the installation. A control cable (cable length 3m, maximum 100m) is supplied with the transceiver, and a commercially available LAN cable Cat-5E 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 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 transceiver 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.

IC-7760 dual 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.

IC-7760 Receiver Block Diagram

The receivers 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.

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-7851 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.

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.

IC-7760 transmitter :

The DPD (Digital Pre-Distortion) function corrects non-linear distortion at the final amplifier by applying inverse distortion in advance. A clean signal transmission is achieved while providing 200 Watt of high output power at the same time. The DPD function also works at the 1 kW output in combination with the IC-PW2 power amplifier.

The IC-7760 uses a 450 Watt-class 65 Volt LDMOS-FET in the PA section, combined with a large heat sink 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. By using 450 Watt FETs device in 200 Watt output, the PA achieves excellent IMD characteristics.

The transceiver incorporates a mechanical relay type internal antenna tuner (ATU) as a first for ICOM's 200 Watt 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.

IC-7760 dual display :

The IC-7760 control head has main and sub dual displays. The displays are one 7-inch main display (800 x 480px) and one 2.4-inch sub display (320 x 240px) and both displays are touch screens. The main display shows information necessary for operation, including MAIN/SUB operating frequencies, setting/operating status of each function, as well as the spectrum scope, S-meter, and RTTY/PSK31/63 decoding messages. The sub display can show the 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 you visible images of twin PBTs, manual notch effects. The improved visibility of information enhances operability and ensures smoother operation.

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. Dual scopes can be shown left-to-right or top-to-bottom layout, depending on the situation and needs. 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.

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 next to 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.

IC-7760 dual speakers :

The ICOM transceiver 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 set for stereo or mono output from both speakers.
