Independent A/D converters into the FPGA. Two separate DIGI-SEL preselectors, two separate Band Pass Filter networks, feed two Receivers in the IC-7610 have you covered. 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 Also, a 10 MHz reference signal can be input to the Utilises a low phase noise VCXO (Voltage Controlled Crystal Oscillator), combined with Icom’s years of technical expertise to design aĬommon 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 hear as the desired signal comes out of the pileup! Out of the noise of strong adjacent signals. This performance gives you the ability to pull weak signals The RF Direct Sampling system in the IC-7610 is capable of 110 dB RMDR. This process dramatically reduces distortion that naturally occurs in the various mixer stages found in traditional superheterodyne ![]() RF signals are digitized by the Analog-to-Digital Converter and immediately processed by the FPGA (Field-Programmable Gate Array). Introduced with the IC-7300, Icom’s RF Direct Sampling System has made SDR performance affordable. The IC-7610 introduces dual RF direct sampling receivers, achieving 110dB RMDR, rivalling 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 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 DXersĪnd Contesters around the world.
