After sophistication and deepening,
RF direct sampling has gone further.
Far away, DXer pursues a faint signal that reaches from the back of the earth through the ionosphere.
The success or failure is divided into the influence of blocking on the proximity strong signal on the reception sensitivity, that is, the RMDR characteristic.
The IC-7610 realized an outstanding numerical value of 110 dB (at 2 kHz detuning) of RMDR approaching a flagship machine through trial and error including adoption of RF direct sampling method and selection of parts in clock generation circuit.
It also features dual scope, which monitors different bands and different modes, a high-speed, high-definition real-time spectrum scope and a waterfall, which also brings overwhelming superiority to contestants and DX hunting.
A new horizon of HF that RF direct sampling has opened up.
Acquiring the IC – 7610 is exactly the best performance in that vast new world.
