Hi folks - I very seldom have ever needed to use a notch control, but the other night I used one on another rig and was surprised at how well it worked and useful. Have I missed something or is there no notch control on the K2/100 and if not, why not? Looks like it was pretty standard on rigs at least as far back as Drakes. Can some one clue in the clueless. Thanks. 73/Tim NZ7C
