Icom IC-7610 RF Direct Sampling System

Dual RF direct sampling receivers. The IC-7610 employs an RF direct sampling system, where RF signals directly convert to digital data and then processed by the FPGA (Field-Programmable Gate Array). This process reduces distortion that naturally occurs in the various mixer stages found in traditional superhetrodyne receivers.

The RF Direct Sampling System in the IC-7610 is capable of 110 dB* RMDR. This performance gives you the ability to pull weak signals out of the noise of strong adjacent signals. There is a difference you can actually hear as the desired signal comes out of the pileup!

RMDR Characteristics
* Representative value at 2 kHz frequency separation (Received frequency: 14.2 MHz, Mode: CW, IF BW: 500 Hz)

Independent Dual Receiver

Whether listening to both sides of DX station running split, or looking for a multiplier on a different band or mode, the dual receivers in the IC-7610 have you covered. Two separate DIGI-SEL preselectors, two separate Band Pass Filter networks, feed two separate A/D converters into the FPGA.

Dual Digi-Sel

The DIGI-SEL preselectors are RF filters with sharp, narrow passband characteristics preventing Analog-to-Digital Converter overflow from large out-of-band signals when sampling the RF signals. Additionally the third and higher order IMD components are reduced. This is ideal when strong signals are received in a contest pile-up or from broadcast stations on adjacent frequencies or bands.

Large Color Touch Screen

The large 7” color TFT touch LCD offers intuitive operation of functions, settings, and various operational visual aids such as dual spectrum scope aligned vertically or horizontally, simulated analog meters and RTTY, PSK31/63 mode decoded messages.

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 by touching the screen and can adjust the levels by turning the multi-dial knob.

Frequently Asked Questions (FAQ)

Can it duplex? No, but it can receive on different (or same) bands using separate antennas.
What type of mic does it use? Good news, you have many choices made easy because you can turn off mic DC power when using non-Icom microphones.
Can the connected mouse on the LCD be used to click on soft buttons in the LCD? No, just clicking the frequency in the waterfall and it's functions.
Can I use a wireless mouse/keyboard combination? Yes.
Can I transmit over the air, a recorded QSO directly from the transceiver? Not directly from the radio.
Can it do RTTY (FSK)? Yes, either with a connected keyboard or with PC software. No Mac software does FSK that I am aware of.
Do I need something like a Signalink to operate PSK? No, just the radio will suffice.
Can it do SO2R? No, it will SO2V.
Can I separate the main and sub audio so I can listen to one frequency in my left ear and another frequency in my right ear with my headphones? Yes
Is it capable of diversity receive? Yes. “Diversity reception” means - same frequency is received by different antennas.
Will the Icom IC-7610 support an I/Q output to something like CW Skimmer? It has not been defined yet. Coming in a future update.
Can I use an external touchscreen monitor? There is some talk indicating it may be possible. It would require a touchscreen that doesn't need a driver installed and loaded to work. That's limiting. More will be revealed.
What is the external monitor resolution? You can choose either 800 x 480 or 800 x 600.
