What makes this more confusing is that:

- Low-power stations are supposed to have separate callsigns ("-LD",
"-CD", and just plain "-D"), but for the most part have not been assigned

Title 47.

- Section 2.302, which theoretically specifies the assignment of
callsign formats to different services, has not been updated in a
