What are these "high Q" tones, and why would I want to use one or the other when there are duplicates? The manual tells me basically nothing, and a quick scan of the Web turned up the same.
I'm guessing that this means they have a narrower passband within which they will accept the tone as being "right". If you look at the tone spacing for CTCSS, some of them are only 3Hz apart.
