HF/50MHz/144MHz base station transceiver

The IC-7400 covers HF, 50MHz and 144MHz bands with a powerful 100W of output power and carries on the reputation earned by the IC-746. It offers improved performance and a wide range of new features that are destined to set a new benchmark in this important market. The biggest news of all is that this new transceiver has adopted the same IF DSP as the IC-756PRO and its successor, the IC-756PRO2. ICOM has used a 32-bit floating point DSP and 24-bit AD/DA converter at the heart of the IC-7400, which makes this base station fresh and exciting. Furthermore, the digital IF filter shape is selectable from sharp to soft for both SSB and CW modes. Now let’s just see what else this new rig has to offer the demanding Amateur.

32-bit floating point DSP and 24-bit AD/DA converter
The IC-7400 adopts the 32-bit floating point DSP and 24-bit AD/DA converter in the IF stage. This combination dramatically improves the precision and the scale of the signal processing and provides a wide dynamic range from HF to 144MHz band.

Digital IF filter
DSP is used for the IF filters on all bands. This means no optional IF crystal filters are required for bandwidth selection. Fifty-one different passband widths are available according to operator needs from 50Hz to 3600Hz.

Filter Shapes
No optional crystal filters required or needed! 51 built-in, adjustable filters allow for incredible selectivity. The tuning shapes for CW & SSB are independently selectable. You’ve got to try it to believe it!

AGC loop management
Digital IF filter and manual notch are included in the AGC loop controlled by the DSP unit. It rejects blocking by extremely strong adjacent signals out of the filter pass bands. Therefore, you will never suffer from blocking of the AGC gain. In addition, the AGC constants are adjustable for each operating mode (slow, medium, and fast pre-set).
