I too am awaiting the Icom series International Radio roofing filters. 
The data on their filters certainly look great and should solve a lot of 
front end overloading from adjacent channel interference. My plans are 
to install it plus a Ft-920 International Radio cascaded filter board 
into my Icom 756. It uses the same frequency filter as Icom's 775 and 
765  thus making it into a competitive radio. Inrad's cascaded filters 
idea really does make a difference!  I just installed one into a Yaesu 
FT-980 which I still consider a good radio. DSP still has a way to go 
until processing speeds are reached at affordable prices to utilize this 
technology in the first stages. In my opinion until this happens crystal 
filtering can't be beat. Every time I hear the term DSP it reminds me of 
the dreaded woodpecker. Had it not been for a classified technology 
called DSP return echo's of over the horizon Hf radar would never have 
extracted a signal from the noise. 73's  Charlie  W5VIN
