You can select the filter widths from 15kHz and 6kHz, depending on operating mode. Before the 1st amplifier, the IC-7800?s roofing filters block strong adjacent signals. The mechanical relay reduces secondary distortion at the primary stage of signal processing.Improved blockingContesters know how frustrating it is to experience a strong adjacent signal that?s blocking the receiver from pulling out a weaker signal. This allowed us to explore new technical dimensions.Internal distortion reductionThe IC-7800 uses durable mechanical relays for BPF switching instead of non-linear semi-conductors, like switching diodes which can cause distortion. A first in Ham radio! To achieve this superior receiver performance, Icom?s engineering team completely re-engineered the whole analog circuit and matched it to the DSP units. No one else comes close!+40dBm IP3(3rd order Intercept Point) Icom?s considerable analog RF circuit experience combined with cutting-edge digital technology results in an astonishing 110dB receiver dynamic range and a +40dBm IP3 in the HF bands. The result is TWO identical receivers with 110dB dynamic range, +40dBm 3rd order intercept point, and unmatched DSP technology in the HF bands something that has never been achieved in Ham radio! Simply put, Icom has developed the ultimate Amateur HF transceiver. The IC-7800 will be viewed as the pinnacle radio for years to come.The IC-7800 is an artistic fusion of over 40 years analog RF circuit development expertise and cutting-edge digital technology. It takes amateur radio to a whole new level of performance. Some of today?s operators still feel the IC-781 is the pinnacle in amateur radio design. The IC-781 set benchmarks back in the 1980?s as that generation?s ultimate HF transceiver. Continuing with this tradition, Icom announces the groundbreaking IC-7800!The IC-7800?s somewhat familiar looks will remind many HF operators of the IC-781. Starting with the first analog PLL circuit in the IC-200 to the ground-breaking 32- bit DSP technology used in the IC-756PRO, Icom?s developed some of the most innovative radio equipment ever made.
Icom is a pioneer in the amateur radio world. Compact Flash card for storing personal settings +40 dBm ultra high intercept point. Have you earned it? Do you deserve it? Do you want it?

Therefore I, unlike most sellers, offer a money back guarantee. Translation: "Trust Me, but I don't trust you". I am not ruled by fear of the pervasive mythical "parts swappers" nonsense.
10 MHZ REFERENCE FREQUENCY FOR IC 7800 FULL
FedEx Ground Shipping includes full insured value. I just tested the radio the following are readings using my Bird 4411 wattmeter and Bird 1,000 watt dummy load.
No mic came with this radio and none is included. I do not smoke and my home is non-smoking. The original inner and outer boxes will assure it will be packed for safe shipment to you. It comes with the rack handles and the original manual. Maybe your eyes are better than mine but I don't see any scratches on it. Please place your mouse over the photos to see larger images. The photos are of the actual equipment I am selling. Or a friend or loved one may like to present it to you. Perhaps this radio can be a present to yourself. Are you a radio connoisseur? Is this radio high end? Yes. Do other sellers offer a GUARANTEE? Give yourself the gift one of Icom's best ham radio ever. Here is my beautiful one owner Icom IC-7800 HF/6m Transceiver.
