Sked

Sked is shortened version of the word schedule. It can refer to a flight schedule, a baseball schedule, or any other type of schedule. In the context of amateur radio a sked is a pre-arranged or scheduled contact between ham radio operators.

A sked is a pocket-sized bifold or trifold schedule about the size of a baseball card printed for a sports team. Typically, a team logo or an image associated with the team (a player or the stadium or arena, for example) appears on the front, one or more sponsors are listed on the back. Inside is a listing of the season's home and away games.
