IF filter output which has only passed the intended signal and draws the full potentialДЇrom the digital IF filter. The other AGC loop detects the AGC voltage at the digital The first AGC loop prevents saturation of The AGC voltages detected in front of and behind This system provides wide dynamic range, reducing the distortionДЇrom strong signals and lower intermodulation. Reduces signal distortion through IF processing and provides a high-fidelity signal The image rejection mixer for the 2nd stage The 1st mixer stage is driven with a signal from the high-drive System composed of a DMOS FET 1st mixer and a newly developed image rejection mixerДЇor the 2nd stage. Spurious signals and distortion from transceivers. Simple receiver system configuration is the best way to eliminate sources of the Is manually adjustable from the DIGI-SEL tuning knob on the front panel. It automatically tracks the intended signal keeping the pre-selectorвЂ™sД«andwidth centered on the operating frequency. The pre-selector works between 1.5MHz and 30MHz and rejects distortion componentsДerived from out of band interference such as multimulti operation or strong broadcast (FM mode is fixed to 15kHz.) IcomвЂ™s DIGI-SEL Select the filter widths from 15kHz, 6kHz and 3kHz, depending on operating mode. The IC-7800вЂ™s three roofing filters block strong adjacent signals. Relay reduces secondary distortion at the primary stage of signal processing.Д¬ontesters know how frustrating it is to experience a strong adjacent signal thatвЂ™sД«locking the receiver from pulling out a weaker signal. Semi-conductors, like switching diodes which can cause distortion. The IC-7800 uses durable mechanical relays for BPF switching instead of non-linear The whole analog circuit and matched it to the DSP units.

This superior receiver performance, IcomвЂ™s engineering team completely re-engineered (3rd order Intercept Point) IcomвЂ™s considerable analog RF circuit experienceД¬ombined with cutting-edge digital technology results in an astonishing 110dB receiverДynamic range and a +40dBm IP3 in the HF bands. Icom has developed the ultimate Amateur HF transceiver. In the HF bands something that has never been achieved in Ham radio! Simply put, With 110dB dynamic range, +40dBm 3rd order intercept point, and unmatched DSP technology The IC-7800 is an artistic fusion of over 40 years analog RF circuit developmentД®xpertise and cutting-edge digital technology. The IC-7800 will be viewed as the pinnacle Radio to a whole new level of performance. Some of todayвЂ™s operators still feel the IC-781 is The IC-781 set benchmarks back in the 1980вЂ™s as that generationвЂ™s The IC-7800вЂ™s somewhat familiar looks will remind many HF operators of the Continuing with this tradition, Icom announces the groundbreaking IC-7800! IC-756PRO, IcomвЂ™s developed some of the most innovative radio equipment ever Starting with the first analog PLLД¬ircuit in the IC-200 to the ground-breaking 32- bit DSP technology used in the Icom is a pioneer in the amateur radio world.
