The Accumulation of 40 years of Hard Work and Technical Expertise.
Tokuzo Inoue President, Icom Incorporated

I am proud to make this introduction of a new product. I first became licensed as JA3FA in 1953. In the 1950's I modified a 1 RF/2 IF receiver to a 2 RF/2 IF unit, and at that point, had my first experience with intermodulation caused by saturation of the mixer stage. This was to be the beginning of the battle to continually improve the performance of a receiver.

The modes of operation at the time were CW and AM, but I remember the difficulty of obtaining sensitivity, selectivity and stability, the so called three S's, in a receiver in particular, like it was yesterday.

In 1964 we developed the all solid-state 50MHz portable transceiver, the FDAM-1, and also in 1977, with the development of the same all solid-state HF transceiver IC-710 etc, Icom was always at the forefront of transistor technology.

However, at the same time the subject of improved receiver performance has been a daily battle and challenge. One of these challenges was the development of the HF transceiver, the IC-780, in 1988. It is now 15 years later. SSB has been the HF mode of choice, and the explosion of amateur user's, increases in output power, large beam antennas etc., has caused the electrical field of interfering signals to increase.

Now, just at the time that even further improvement in receiver performance is yearned for, Icom has developed a receiver with an astonishing +40dBm third intercept point, performance to defy all existing standards today. This outstanding technological achievement is not limited only to the improvement of the front-end dynamic range, but also applies to the low-noise Lo, high CN ratio and other high-performance specifications, to provide the necessary balance for unparalleled performance. The result is the ability to fully enjoy the performance of a DSP filter with more than 100dB of out-of-band attenuation. Of course, we have included the right balance of technological secrets in the transmitter too.

Icom Inc. is celebrating its 40th anniversary of incorporation, and it is my pride and pleasure, and also that of every Icom employee, to present to you the IC-7800, the +40dBm third order intercept point ultimate HF transceiver.
