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.
