OK, If I am interpreting your results correctly it doesn't seem too bad.

You can try, if you wish, also adjusting T12 in the same cautionary fashion as the others to see whether that is already on-target or not. If it turns out to be well out, it might pay you to run carefully through the T9-T10-T11-T12 chain all over again. On the other hand you might take the view that if it isn't broken, don't fix it. It's entirely up to you how much time you want to devote to it. You certainly don't seem to be short of patience.

I did remember there's a minor issue with the SSB squelch threshold, I think we'll leave that until later and maybe make some headway on the transmitter when you're ready.
