ICOM IC-7400

ICOM unveiled IC-7400 at 2001 Ham Fair. The price is 218,000 yen, which is 20,000 yen higher than IC-746. It looks just like IC-746, but its inside has drastically been redesigned. IC-7400 uses a DSP-based IF circuit, which is very similar to IC-756PROII.

The outstanding features are:

• 32-bit floating point DSP and 24-bit A/D D/A converters.
• Digital IF DSP filter - user can change its shape factor during RX on the fly (just same as IC-756PROII)
• High cost performance - 1.9MHz to 144MHz coverage, 218,000 yen
• Improved dynamic range with new designed RF and mixer circuits
• Clear TX signal with the DPSN modulation - better than IC-746 by over 10dB
• RTTY decoder with a DSP twin peak filter
• Manual/automatic notch filter
• DSP noise reduction
• DSP speech processor
• Digital mic equalizer
• Level adjustable noise blanker
• CW reverse

This is a very quick view of IC-7400. I will keep updating the information...........
