AM Transmitter Schematic on Welcome Back Kotter - "Sweatwork"
Videos for Engineers

It is no secret that I have been a long-time fan of the TV show Welcome Back Kotter, which centers around Buchannan High School, a fictitious Brooklyn, NY, institution of learning, and a gang of affable, low-achiever Sweathogs. Gabe Kotter, a reformed former Sweathog himself, is now a teacher of Social Studies at Buchannan. He is the only person able to coax any semblance of respect or conformance from them. It was a simple, clean show, typical of 1970s Prime Time television.

In the episode embedded below, titled, "Sweatwork," (play on Network), provided by Hulu.com, is about the Sweathogs running a radio station in the school. On the blackboard outside of the broadcast studio is a schematic for an AM transmitter. It looks legit, and includes all the components to form a basic AM transmitter, including the audio input. The scene in the screen capture occurs approximately 6 minutes into the show, then appears in many other scenes.

† "Sweatwork" is a variation of the 1976 movie "Network." The famous scene in Network is where the broadcast anchor prompts all his viewers to go to the window and yell ,"'I'm as mad as hell, and I'm not going to take this anymore!" Arnold Horshack does his own interpretation of the scene on his radio broadcast. Strangely, 33 years later the same sentiment exists; it appears we kept on taking it after all.
