[ICOM] Query.

Mike,
As Mac has stated, most modern rigs will be prone to letting in some 
trash but the beauty of the 2720, the 2800 before it, and most newer 
Icom dual band rigs is that they have a RF gain control. It has to be 
enabled through a menu setting but when enabled the squelch control from 
about 12:00 on becomes the RF gain control. Full gain reduction is on 
the order of 10 db. I find that when I encounter interference usually 
just a modest amount of gain reduction takes care of it. Even in extreme 
circumstances when I use full gain reduction, being only 10 db it 
doesn't knock out the local repeaters. Filters are nice but if you don't 
want to purchase them then just dial in some gain reduction.
