Narrative:

I was on a vector SID departing slc to lgu. My clearance was: cleared to lgu, jazzz 2 departure, V21 ogd, then as filed, 10000 ft. We were level at 10000 ft and on a vector of 300 degrees. We flew through V21. I turned to a heading of 360 degrees to intercept V21. I misunderstood the clearance - I thought I was on a vector to intercept V21, but I was not. The controller's clearance was only to 'fly heading 300 degrees', not 'fly heading 300 degrees and join V21.' I have enclosed a copy of the SID.
