Icom has been developing radio communication equipment for over forty years. Its heritage has always been based on technical excellence from the first analogue PLL circuit in the IC-200, to the ground-breaking 32-bit floating point DSP of the IC-756PRO. 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 flagship model IC-7800 which is a fusion of forty years analogue RF circuit development expertise, with cutting edge digital technology. The result is 110dB dynamic range, +40dB 3rd order intercept point in HF bands and other phenomenal performance features. The receivers combine various current and new technology, to obtain the +40dBm IP3.
