OK, backtrack a little bit to C539 in circuit area C2, sheet 3 - set your scope as you would to look at audio (as a rough guideline, adjust the horizontal timebase until the scanning line only just becomes a solid line, that will put it in the right ball park area).

On C539, the input to which you will see is labelled 'SSB MOD', you should see audio when you key the microphone and speak into it.
