Typed caption on verso: "E. This is a combined motor generator and transmitter to operate on 3015 and 3120 KC. It was produced in quantities of about 200 during 1935-1937, and was generally used with a trailing wire antenna. It was one of, if not the first, private flyer transmitting equipment sold, so that the flyer could ask CAA ground stations for specific information they required regarding weather and also to get position reports."Creation Datecirca 1935-1939SubjectLear DevelopmentsLearadioRadio--Transmitters and transmissionRadio in aeronauticsAids to air navigationExtent1 photograph : black and white ; 8 x 10 inOriginal Formatphotographic printscomposite photographsBibliographic CitationThe William P. and Moya Olsen Lear Papers/The Museum of FlightRightsCopyright undetermined
