Narrative:

Sbd ATIS is often unusable due to strong 'buzzing' interference on their ATIS frequency; 124.17. The tower reports they don't hear it. I suspect the tower spends very little time actually listening to their own ATIS on frequency. The interference is not present on ground or tower frequencies; or on socal approach. When the buzzing is at its worst; it is impossible to copy the ATIS. Since tower operational hours are inaccurately reported in the pilot association airport directory; this creates the potential for a pilot to operate in the class delta without contacting the tower; as the ATIS is unreadable. At other times; the buzzing is intermittent; so that with several passes through the ATIS most all of the pertinent information can be heard. But even then; there's the potential to miss an important detail.
