So while I love my IC-735, the one feature it lacks that I'd really like is a narrow passband filter. The passband tuning on the 735 is great for killing one half or the other of a signal, but when I'm working digital modes calling CQ I'd really like to be able to block out the strong local signals that overload my sense (I think is the right way of describing the problem.) Without going over ~$800 what's a good radio to start looking at?
