Narrative:

The incident occurred on departure from and, sc, on jun/sun/01 at approximately XA00. I used the wrong frequency of 122.9 to announce my departure from runway 23. Wind was calm and I was not aware of any other traffic. I noted a small twin engine aircraft turning onto runway 5 for departure. The sloping runway prevented my seeing the other aircraft until I was well airborne. The incident could have been prevented if I had read the correct frequency from my airport directory or my NOAA approach plate that were on board at the time. Also, if greer approach had suggested the correct frequency, this would have helped.
