Direct-sampling/digital up-conversion HF/6m transceiver with two independent, identical receivers
MAIN and SUB receivers can operate independently on different bands and modes (emissions)
SUB receiver tuning knob available by plugging RC-28 controller into front-panel USB-A port
MAIN/SUB Tracking (simultaneous tuning) from main tuning knob (enabled by menu option)
Each receiver front end has dedicated ADC, ADC driver/preamp, 0-45 dB X 3 dB step attenuator, BPF group and Digi-Sel tracking preselector
Separate DAC/audio chains for MAIN and SUB receivers; binaural reception possible
Powerful ALTERA® RF FPGA performs digital down/up conversion, frequency-management and signal-processing tasks
Separate Lattice® Common FPGA performs signal-processing tasks
Separate AF/SQL controls and EXT SP jacks for MAIN and SUB receivers
Independent MAIN and SUB real-time FFT spectrum scope/waterfall displays with high dynamic range (100 dB)
Separate scope RBW (resolution bandwidth) and VBW (video bandwidth) adjustments in Spectrum Scope menu
Independent MAIN and SUB spectrum scope/waterfall displays(can be stacked L/R or MAIN above SUB)
Dual clock displays
Headphone left/right mix can be turned on or off
MULTI knob for easier operation (similar to IC-7300)
ANT1 and ANT2 ports with switched hybrid splitter for user-selectable dual-antenna (e.g. diversity) or Dual Watch configurations
RX ANT IN/OUT BNC break jacks switchable between MAIN and SUB receiver
10 MHz EXT REF I/O and Transverter I/O BNC jacks
NTP (Network Time Protocol) server connectivity (when IC-7610 is connected to Internet)
RF-FPGA has MAIN and SUB inputs (from ADC's) and outputs (to DAC's), and display data channel to display driver subsystem
CW keying waveform generation & shaping in FPGA to minimise latency
CW RX APF function with adjustable position (f0), width and AF gain
Low-noise, high-performance 16-bit ADC's (Linear Technology LTC2208I); sampling rate 122.88 MHz
Low-noise ADC driver with high gain-bandwidth product (Linear Technology LTC6409)
High-quality 24-bit, 192 kHz stereo audio codec encodes transmit audio and decodes Main and Sub receive audio
Digital up-conversion (DUC) exciter and 14-bit DAC (ISL5961IAZ) offer exceptionally low TX phase noise and clean transmitted signal
New low-phase-noise clock oscillator with Crystek ultra-low-noise VCXO provides high target RMDR of 105 dB (1 kHz offset), 110 dB (2 kHz offset) and excellent transmitter phase noise performance
Common low-noise power supply for the VCXO and FPGA helps assure ultra-low phase noise
100W MOSFET PA unit with fast T/R switching
High-speed relay-type auto-ATU with emergency mode to match highly-reactive antennas
Ethernet LAN port supports internal RS-BA1 server as in IC-7851, IC-7700 (FW V2.0 & higher), IC-7800 (FW V3.0 & higher)
LAN Output Select menu option for AF (baseband) or IF
Multiple memory functions
Two rear-panel USB-B ports (USB2 & USB3) for CAT control/PCM audio & I/Q baseband output (now supported in Firmware V1.20).
Future 12 kHz final IF I/Q output via firmware upgrade
Two front-panel USB-A ports for USB stick, mouse, RC-28 controller, keyboard etc.
SD card slot for data capture, record/playback, firmware upgrade etc.
Firmware upgrade via SD card or USB stick
External meter and keypad jacks on rear panel
7" (diagonal) high-definition touch-screen display
Screen image capture to SD card
Scope/waterfall windows can be stacked side-by-side or MAIN above SUB
Multi-purpose real-time audio scope and FFT audio spectrum analyzer
Rear-panel DVI-D port for external video display
External display resolution selectable via menu: 800X600 or 800X480
Large RAM reserve for future firmware expansion
Dimensions & weight: 340 (W) X 118 (H) X 277 (D) mm, 8.5 kg
Operating refinements:
Mute band by pressing corresponding volume knob
Mic DC bias can be disabled for dynamic mc
Keyer memories can use F1-F8 on keyboard
Can record and capture directly to USB drive or SD card
Adjustable independent beep tones for the main and sub bands from 500-2000Hz
