[Elecraft] Possible K2 sidetone mod

[dw]

I don't have my K2 yet
but should have it in about a week..depending on
options.
I noticed in the schematic that the side-tone output(U10B pre-amp) looks
to
be connected as a secondary input to AF-amp(U9 LM380).
This makes me assume that side-tone volume is not fixed, but instead
changes along with, and is a percentage of AF volume.
If that is true, its a setup that I don't prefer.

My (off-the top of my head) solution would be to splice in a 2N3904 on
the output of U10B, and then move that output over to
AF-OUT.

That way, I always have a fixed side-tone volume, no mater what the AF
volume is set at.

Has anyone else done something like this already?

Thanks
