My figures were taken at 80m frequencies so will not compare too well with your band selection.

Yes, Q6 and Q7/8 do seem to be working.

If the two different ranges can be compared, yes. My figures show a voltage increase after L1/C2 but will 10m be the same?
Later... I have checked my 6.3 and put my findings for 10m on my page.
<http://sites.google.com/site/g4zfqradio/levels-measured-in-a-softrock-tx> I do see higher readings after L1/C2.
But do not expect too much on 10m.
