Innovative RF Direct Sampling System Achieves 110 dB* (typ) RMDR

The RF direct sampling system directly converts the analog signals to digital signals, and collectively puts the data through FPGA (Field-Programmable Gate Array) processing. The master clock uses a high precision VCXO (Voltage Controlled Crystal Oscillator) which excels in low-noise characteristics. This makes it possible to provide superior receive and transmit performance, extremely low phase noise as well as high RMDR (Reciprocal Mixing Dynamic Range).

*At 2 kHz frequency separation.

Independent Dual Receiver Receives Two Bands Simultaneously

The dual receiver is ideal for simultaneous monitoring of two bands and two modes. The sub receiver works independently of the main receiver. The optional RC-28 can be used as the main dial for the sub band.

Superior Transmit Phase Noise Characteristics

Breaking with tradition of mixing a carrier signal with a local oscillator, a Digital-Up-Conversion (DUC) is used for generating required frequencies by sampling the Digital to Analog Converter (DAC). The superior Phase Noise characteristics provide high purity transmit signals.

DIGI-SEL Firmly Shuts Out Interference Signals

Both main and sub receivers are equipped with DIGI-SEL (digital preselector) units. The DIGI-SEL has steeper skirt characteristics than normal band-pass filters, so it rejects out of band strong interference such as broadcast stations, and prevents cross modulation.

High-Speed, High-Resolution Real-time Spectrum Scope

The real-time spectrum scope of the IC-7610 shows main and sub band conditions. It provides class-leading performance in resolution, sweep speed and a 100 dB of dynamic range. The waterfall screen allows you to find weak signals by showing the spectrum change over time. Connecting a PC mouse to the USB port aids in flexible use of the spectrum scope.

FFT Scope and Oscilloscope for Audio Observation

The audio scope function shows the FFT scope with waterfall and the oscilloscope of either transmitting or receiving audio. This function can be used for observing various AF characteristics such as microphone compressor level, filter width, notch filter and receive keying waveform in CW mode.

Touch Screen and Multi-Dial Knob for Smooth Operation

The combination of the touch screen and the multi-dial knob offers quick and smooth operation. When you push the multi-dial knob, menu items are shown on the right side of the display. You can select an item with a touch of the screen and adjust levels by turning the multi-dial knob.

DVI-D Connector for External Display Connection

The IC-7610 has a DVI-D digital connector for an external display. Operating frequency, setting information and spectrum scope can be observed on a large external display.

High Sound Quality Speaker

The IC-7610’s speaker offers comfortable sound quality with flat overall frequency response and loud and intelligible audio for making use of the high-purity received signal. Insulators are placed between the speaker and chassis for preventing vibration noise.

SD Card Slot and USB ports for Saving Data

For multi-operators using one rig, personal settings such as filter settings, memory channels, and antenna settings, can be loaded using the SD card/USB memory stick. TX Voice memories and RTTY/CW memories on the SD card/USB memory stick can be sent with a touch of button.

I/Q Signal Output

The I/Q signal output function* allows you to derive digital IF signals from the I/Q output jack. It can be used for analysing spectrum or decoding signals.

*This function will be provided with a future firmware update. A third-party software may be required separately.
