[ICOM] QST - 7600

[Jan Robbins]

Hi Ekki,
I don't remember the exact noise floor figures for the 756ProIII, but 
those reported
for the 7600 in QST are -131  -139   -141 for 3.5 thru 14 mhz (preamp 
off, on 1,  on 2),
and I doubt the ProIII is any "better" than that, if as good.

One definite statement the QST reviewers make is, "All told, this 
performance [two-tone, third-order
IMD at 2khz spacing] is SUBSTANTIALLY superior to the ProIII's." 
[emphasis in original]  Given that the ProIII
had only one (15khz) roofing filter, this could scarcely NOT be the case.
