[ICOM] Icom 7700 vs 7600

[Adam Farson]

Hi John,

Yes, both the 7600 and 7700 have 15, 6 and 3 kHz roofing filters at the 1st 
IF (64.455 MHz). These filters are optimised for minimum passive IMD.

All selectivity filtering takes place in the DSP at the 36 kHz second IF.

Here are my user reviews and test reports on the two models:

Cheers for now, 73,

How much better?  I realize that is kind of a subjective question, though. 
The 7600 does some with roofing filters as standard, correct?
