Hi Isaac,
Three major differences between the IC-756Pro II and the IC-7400 (IC-746Pro)
are:
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.

Hello All
Any comments to help me choose between the 7400 (746PRO ? 746PRO-II ?) and
756PRO-II ?
Thanks in advance, 4Z4TL, Isaac.
