 Nate Pope (Forest Whitaker (qv)) is an Amateur Radio operator with  the call sign WB6QLF. QLF is amateur shorthand for "I am sending  with my left foot", a reference to someone whose Morse Code sending  skill is very bad. This is normally sent as a question "QLF?"  meaning "Are you sending with your left foot?" to an operator who is  very difficult to understand in Morse.
