Going from memory here...we had a standard format worked into our computers when we typed up the transcripts. On the upper left hand side we typed the date on the first line, radio/tv station/network on the second, hour of the day it was broadcast on the third, and name of the show it was part of on the last line. You may want to be more descriptive of the actual time during the show it came on.
Each section was typed with the speaker's name at the left, then indented. Commercial breaks were broken up with centered asterisks, and we used that again at the end of the transcript.
The company had worked out legal details ahead of time...the work of the broadcaster isn't supposed to be used for free, even though you hear it on public airwaves. I don't imagine anybody will be after you for this individual copy, however!
