Hello John,

 From what I understand, and the IC756 versions are as deaf as the IC746 models.  I 
believe somebody measured them with a front end noise figure of around 5 dB :-( 
However, this is NOT at all unusual for modern transceivers, which are trying to 
minimize distortion with strong signals.  If you are interested in weak signal work, 
I strongly urge you to consider getting a low noise external preamplifier such as a 
CA50T from LNA:
