Icom has been developing radio communication equipment for over forty years. Our history has been technical challenge and excellence from the first analog PLL circuit in the IC-200, to the ground-breaking 32-bit floating point DSP of the IC-756PRO. Icom has always given shape to ideas with this technical accumulation. Recent Ham radio stations increasingly use high power and high gain antennas that raise the field strength of unintended signals, and thus require a wider receiver dynamic range. Icom has developed the new flagship model IC-7800 which is a fusion of forty years analog RF circuit development expertise, with cutting edge digital technology.
