I have searched but been unable to find two things. 1. Will NNOT CCHANS 214 exclude anything on channel 214? If not, is there a way to exclude a channel rather than to select a channel. 2. Can you use part of a word. For example, for many races I just want to see the race so I have used NNOT PRACTICE QUALIFYING, which does work. However, it makes for a long string and I would prefer NNOT PRAC QUAL. I have also tried TOURING TTITLE NNOT AUST PRAC QUAL CCHANS 214 It is not clear these work, but I may be doing something wrong. As you can see the problem is the 50 char limit vs. the need to refine a search.
