[GreenKeys] using a scope for rtty

[Eugene Hertz]

Hi All,

Now that my rtty station is shaping up, I decided to pull out my tektronix 604 XY Monitor out of storage.  And I connected it to my ST6 and had a question. 

Seems I was expecting a vertical ellipse and a horizontal ellipse corresponding to mark and space (or maybe space and mark, I forgot which is which).  However the horizontal was not quite horizontal and the vertical was not quite vertical!  The horizontal seemed to go up hill and the vertical had a similar angle.

Now, I took my precision digital function generator and programmed in 2125 and 2295 so I know I'm putting in the right freqs.  So why is this so? Does this mean that my ST6 is not quite tuned properly? Does it mean my XY scope is off? 

Thanks
Eugene
