 design (-104 dBc/Hz at 2 kHz offset, as compared to -111 for the IC-765 and
 -125 for the IC-756Pro2). This led to relatively poor close-in reciprocal

Hi Adam,
    Regarding the '751A, you mentioned a noisy synthesizer.  Perhaps that is 
what I noticed--something I had had always attributed to a noisy audio chain.  
A good friend had one which I frequently used.  When he upgraded he offered 
the '751A to me at an attractive price.  I thought about it for an hour and 
decided against it because of its omnipresent "white noise".  It could have been 
unique to that particular radio, but I found that listening to the '751A 
became very tiring after just a few hours.  
    FWIW, the '756PRO series [all flavors] seems to lack that 
(annoying-to-me) "white noise" component.
