RF Direct Sampling System
The IC-7610 employs an RF direct sampling system and has 2 completely independent and identical receiver
circuits for the Main and Sub bands from the antenna to the AF output. RF signals are directly converted to digital
data and processed in the Field Programmable Gate Array (FPGA). This system is a leading technology marking
an epoch in amateur radio.
