perth technical school at its annual demonstration 9 december 1904 included a note: "a very popular resort with visitors was the electrical classrooms, in which interesting demonstrations were given. the apparatus includes some of the instruments used by mr. soddy in his recent "radium" lectures, notably an apparatus for showing high frequency currents." the school's annual report for 1904 reveals incidentally further detail of the soddy instruments: "mathematical and physical department. during this year the work of this department has largely increased with the influx of students, but mr. allen and his assistant, mr. clucas, have proved equal to the demands made upon them. the appointment of a second assistant will enable important developments to be made. indents have just been despatched for further valuable apparatus, and soon this school will be fully equipped for the training of electrical and other engineers. one very important gain to this department last year was the acquisition by purchase of most of the apparatus used by mr. soddy in his university extension course on radium." it seems unlikely that the lodge-muirhead equipment was included in the acquisition, given that that group also fiercely protected its patents, but equally the core equipment would have been easily leveraged into wireless equipment by the lecturers and students of the school.
