In the United States all radio and television stations are represented by "call letters". Each set of call letters is 4 letters long. Call letters for stations east of the Mississippi river begin with a "W", while stations west of the river begin with "K".

Using the description of their station and/or the format, figure out the call letters of these fictional stations. (e.g. A station for people getting their affairs in order before they die might be WILL.)

Note: Some stations will use phonetics opposed to exact spelling.

1) A station all about a certain type of fish.
2) A station all about a green leafy vegetable high in beta carotene.
3) A station all about small metal containers used to package soda.

East of Mississippi River:
1) A station all about Pink Floyd's well known 1979 album and 1982 movie.
2) A station about the different energy measurements of light bulbs.
3) A station about how to get rid of unwanted plants in your yard or garden.
