What ground-based, airline job in the 1940s could have involved radio communications? My mom worked for United Airlines in the mid 1940s in some communications capacity: she communicated by radio with United aircraft only, and she wasn't an air traffic controller.  She went to school in Kansas City in 1942 for communications. 

Could anyone help me figure out what her job would have been?
Perhaps she was a flight dispatcher?

A flight dispatcher (also known as an aircraft dispatcher, airline
dispatcher, flight follower or flight operations officer) assists in
planning flight paths, taking into account aircraft performance and
loading, enroute winds, thunderstorm and turbulence forecasts,
airspace restrictions, and airport conditions. Dispatchers also
provide a flight following service and advise pilots if conditions
change. They usually work in the operations center of the airline.
