Faint signals are no longer a challenge for DXers and Contesters around the world, with the new IC-7610. The difference between putting the QSO in the log or trying another time is the capability of your receiver. The high performance RMDR in the IC-7610 has the ability to pick out the faintest of signals even in the presence of stronger, adjacent signals

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.
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.
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.
