The standard used by North American Fast Scan ATV (Amateur Television) stations is NTSC. This standard, which stands for National Television System Committee, was widely used for analog television broadcasting in the United States and many other countries in North America. NTSC delivers video at a frame rate of approximately 30 frames per second and has a resolution of 480 lines.

ATV enthusiasts in North America adopt NTSC as it is the prevalent format that many existing consumer television sets are designed to handle. This compatibility allows for a broader audience reach and simplifies the transmission process.

The other standards mentioned are not used for North American Fast Scan ATV. PAL, which stands for Phase Alternating Line, is predominantly used in Europe and parts of Asia. DRM, or Digital Radio Mondiale, is primarily a digital audio broadcasting standard and not directly applicable to television. Scottie, a lesser-known system, is not usually associated with Fast Scan ATV in a North American context. Therefore, NTSC remains the correct answer due to its historical and practical use in the region.
