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. The Audio Scope screen shows both a FFT scope with waterfall along with an oscilloscope for both transmit and receive audio. *Number of pixels shown at the 60 dB level, when receiving a signal.

To navigate around the band easier, connect a PC mouse to the USB port for point and click tuning of the receivers. The scopes provide class-leading performance in resolution, sweep speed and a 100 dB dynamic range. 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 IC-7610 provides dual reception, on different bands, as does the high-speed, high-resolution spectrum scopes. 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. *Output power not guaranteed and power may be reduced.ħ-inch Color Display with Touch Screen Function The emergency tuner function* enables you to operate for short periods of time with an antenna with a high SWR. 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 chart to the right shows the difference made by this new design. 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.īreaking 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. To finish out the receiver, is an internal speaker cabinet. This is ideal when strong signals are received in a contest pile-up or from broadcast stations on adjacent frequencies or bands.Ī) BPF and preselector passband characteristics receiving on 7.22 MHzī) Passband characteristics between the antenna and the preselector (at the preselector output) Additionally the third and higher order IMD components are reduced. 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. Two separate DIGI-SEL preselectors, two separate Band Pass Filter networks, feed two separate A/D converters into the FPGA. 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. Also, a 10 MHz reference signal can be input to the IC-7610 for higher precision. 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.
Reducing phase noise in a receiver is always a challenge as it is a natural characteristic of a receiver. *Representative value at 2 kHz frequency separation (Received frequency: 14.2 MHz, Mode: CW, IF BW: 500 Hz)Ĭustomized VCXO Is Used for the Master Clock There is a difference you can actually hear as the desired signal comes out of the pileup! This performance gives you the ability to pull weak signals out of the noise of strong adjacent signals.
The RF Direct Sampling System in the IC-7610 is capable of 110 dB RMDR. The IC-7610 introduces dual RF direct sampling receivers, achieving 110dB RMDR, rivaling that of top-of-the-line transceivers.
One key factor is the RMDR capabilities, the ability to pick out a faint signal in the presence of stronger, adjacent signals. The difference between putting the QSO in the log or having to try another time is the capability of your receiver. 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.
