===Radio===
He created the American Radio Relay League ([[ARRL]]) in 1914 as a response to the lack of an organized group of "relay" stations to pass messages via [[amateur radio]].  Relaying messages allowed them to be sent farther than any single station's reach at the time. He originally had the amateur [[call signs]] SNY, 1WH, 1ZM, (after World War I) 1AW, and later [[W1AW]], which is now the ARRL Headquarters club station call sign. His rotary [[spark-gap transmitter]] "Old Betsy" has a place of honor at the ARRL Headquarters. The ARRL presents an annual award named for Maxim to a radio amateur and ARRL member under the age of 21.<ref>{{Cite web|title=ARRL Board Confers Awards and Recognitions|url=http://www.arrl.org/news/arrl-board-confers-awards-and-recognitions|access-date=August 6, 2020|website=www.arrl.org|language=en}}</ref>
