[Icom] IC-746Pro vs. IC-756ProII

Tue, 14 Jan 2003 00:48:44 -0800

Hi Larry,

Here are five major differences between the IC-756Pro II and the IC-7400
(IC-746Pro):

1. The IC-756Pro II has a real-time Spectrum Scope module (actually a
mini-spectrum analyser) which is completely independent of the main
receiver. The IC-7400 "borrows" the main receiver to perform a band sweep
for the spectrum-scope display (non-real-time). The receiver is muted during
the sweep.

2. The IC-756Pro II has two independent physical 1st local oscillators
(synthesisers), allowing Dual Watch operation (simultaneous reception on two
frequencies in the same band and mode). The IC-7400 lacks this capability.

3. The IC-756Pro II has a stronger RF front end than the IC-7400.

The IC-756Pro and Pro II use the ADI SHARC DSP; the IC-7400 employs the TI
DSP. The DSP performance in the two radios is similar.

4. The IC-746Pro has 2m capability; the IC-756Pro II does not.

5. The IC-746Pro has a monochrome dot-matrix type LCD display,
whilst the IC-756Pro II has a full-colour TFT display.

Some reviewers have stated that the 756Pro2 has somewhat better receiver
"numbers" than the 746Pro. Here is a link to a discussion of this:

Can somebody direct me to a feature by feature comparison of the two rigs?

Thanks
