IC-7610 HF/50MHz 短波电台

 

RF Direct Sampling Takes You to the Next Level
with Advanced RMDR and True Dual Receive

Whether it is poor band conditions, or battling to pick out a call in a large pile-up, faint signals have always been a challenge for DXers and Contesters around the world. The difference between putting the QSO in the log or having to try another time is the capability of your receiver. One key factor is the RMDR capabilities, the ability to pick out a faint signal in the presence of stronger, adjacent signals. The IC-7610 introduces dual RF direct sampling receivers, achieving 110dB RMDR, rivaling that of top-of-the-line transceivers.

Innovative RF Direct Sampling System

Introduced with the IC-7300, Icom’s RF Direct Sampling System has made SDR performance affordable. Direct Sampling means incoming RF signals are digitized by the Analog-to-Digital Converter and immediately processed by the FPGA (Field-Programmable Gate Array). This process greatly reduces distortion that naturally occurs in the various mixer stages found in traditional superhetrodyne receivers.

Astonishing 110 dB* RMDR

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!

Customized VCXO Is Used for the Master Clock

Reducing phase noise in a receiver is always a challenge as it is a natural characteristic of a receiver. The master clock of the IC-7610 utilizes a low phase noise VCXO (Voltage Controlled Crystal Oscillator), combined with Icom’s years of technical expertise to design a common power supply for the VCXO and FPGA, yielding an ultra-low phase noise. Also, a 10 MHz reference signal can be input to the IC-7610 for higher precision.

Independent Dual Receiver

Whether listening to both sides of a rare 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.

  BPF units

DIGI-SEL for Main and Sub Bands

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.

High Quality Speaker Sound
To finish out the receiver, is an internal speaker cabinet. The cabinet is tuned to reproduce clear, natural sounding audio, and is insulated from the radio chassis to prevent noise from vibration and panel resonance.

Digital-Up-Conversion (DUC) for Clean TX

Breaking with the tradition of mixing a carrier signal with a local oscillator, a Digital-Up-Conversion (DUC) method is used to generate the required signal from the Digital-to-Analog Converter. The chart to the right shows the difference made by this new design.
Transmit phase noise characteristics

Built-in Automatic Antenna Tuner
The built-in automatic antenna tuner memorizes its settings based on your transmit frequency, so that it can recall the tuning setting when you switch operating bands. The emergency tuner function* enables you to operate for short periods of time with an antenna with a high SWR.
* Output power not guaranteed and power may be reduced.

7-inch Color Display with Touch Screen Function
The large 7-inch color display shows various operating and setting information at a glance in high resolution (800 × 480 pixels.) The display clearly shows various features, for example the dual spectrum scope aligned vertically or horizontally, simulated analog meters and RTTY, PSK31/63 mode decoded messages.

Dual Receivers, Dual Spectrum Scopes
The IC-7610 provides dual reception, on different bands, as does the high-speed, high-resolution spectrum scopes. Whether watching for a band opening, working a rare DX station operating split, or searching for a multiplier, the ability to watch each receiver separately allows the operator to concentrate on pulling in a weak signal. The scopes provide class-leading performance in resolution, sweep speed and a 100 dB dynamic range. To navigate around the band easier, connect a PC mouse to the USB port for point and click tuning of the receivers.

Audio Scope Flexibility
The Audio Scope screen shows both a FFT scope with waterfall along with an oscilloscope for both transmit and receive audio. This makes it easy to monitor AF characteristics such as microphone compressor level, filter width, notch filter, and in CW, you can monitor received CW keying wave forms.

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

Remote Encoder for Second VFO Knob
The optional RC-28 remote encoder enables you to add an external Sub dial for controlling the Sub band. Main band and Sub band can be switched with the F1 and F2 buttons and can be controlled with the RC-28. The LED above the F1 and F2 buttons turns ON to show the active band.

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

SD Card Slot and USB Port for Saving Data
When used with an SD card or USB flash drive, various contents including firmware updates, memory channels, captured screen images, and other personal settings, can be saved and loaded. TX/RX audio, voice memories, RTTY/CW memories and RTTY decode logs can be saved and used on the SD card.

I/Q Signal Output
The IC-7610 enables you to output I/Q signals from the USB connector. They can be used to analyze a spectrum range or to decode signals by a decoder software on a PC.
* This function will be provided in a future firmware update.

Simplified Remote Control for RS-BA1
Whether from a remote part of your home QTH, or on a remote location somewhere around the world, the RS-BA1 software enables you to operate your IC-7610. Not only can you control the radio settings and have both RX/TX audio paths, you are able to display a single band spectrum scope with the waterfall. With the addition of an Ethernet connector, a base station computer is not required.
