Radioteletype: History, Applications & Art
Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. The US Navy Department successfully tested printing telegraphy between…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Radioteletype, one of the stronger structural bridges in this analysis connects Radioteletype with Early amateur radioteletype history. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
