A KC apart, or a MC apart?
If it's a MC apart, this is normal. Actually, closer to 900 KC, depending upon your IF frequency. These would be images. When doing the alignment on HF, you will likely have this. It can be tricky to get the right one. When doing the alignment, use a strong signal at first, but once you think you have the right signal, back your generator off until you barely hear the signal, then check to see if the other one is still there, it should be very weak or gone. Verify proper tracking by backing your generator off 1 MC at a time and check for the signal at that frequency. It should follow very closely.
