[amsat-bb] "High Q" CTCSS tones?

[Greg D.]

Hi folks,

I'm updating a small Predict client that I wrote.  It's part of my station's automation for driving my Yaesu FT-736R under Linux.  There's a table in the 736's manual for the various CTCSS tones, and I see there are 9 codes that are labeled "High Q".  Some of the tones match others in the base table, some are unique.

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.

Thanks,

Greg  KO6TH
