Thanks, I'll play around with the marker output a little more. As I recall, it disappeared completely when I turned the sig gen output to minimum.
I am injecting the marker by connecting the signal generator output to the external marker input of the sweep generator. I suppose I could try connecting it independently.
Yes, the instructions did say to connect the sweep gen at the antenna. In other alignment procedures they specified other connection points. This section was called "retouching picture IF" and you did it after completing all the rest.
I tried connecting the sweep gen at the converter tube rather than the antenna, and the display was much the same.
I don't have much experience using an oscilloscope, so I don't have loads of confidence that what I'm seeing is meaningful. Maybe I should set this project aside and practice viewing waveforms on one of my other restored TVs.
