Surplus Motorola Handie-Talkies found their way into the hands of ham radio operators immediately following World War II.
Motorola's public safety radios of the 1950s and 1960s were loaned or donated to ham groups as part of the Civil Defense program.
Avoid the use of disciplinary jargon or dense theoretical material.
We encourage humor and the use of metaphors to draw connections. Interviews (asking questions), mini-case studies, response to an article, a reflective piece, or something else.
It was created by an engineering team in 1940 at the Galvin Manufacturing Company (forerunner of Motorola).
The team consisted of Dan Noble, who conceived of the design using frequency modulation; Henryk Magnuski, who was the principal RF engineer; Marion Bond; Lloyd Morris; and Bill Vogel.
We intend the blog to be a dynamic way for members of the UW community to discuss ideas, experiences, innovations, adventures, challenges, and research about teaching and learning. The audience for the blog is the UW teaching community, but the blog will be publicly accessible from the CTL homepage.
We invite members of the three-campus UW teaching and learning community (faculty, staff, graduate students, and undergraduates) to submit potential blog posts.
A walkie-talkie (more formally known as a handheld transceiver, or HT) is a hand-held, portable, two-way radio transceiver. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
Its development during the Second World War has been variously credited to Donald L. Typical walkie-talkies resemble a telephone handset, with a speaker built into one end and a microphone in the other (in some devices the speaker also is used as the microphone) and an antenna mounted on the top of the unit. A walkie-talkie is a half-duplex communication device.
