These are GNUzipped files of a Hartley Oscillator article by George Grammer from 1932 with notes and construction hints and adaptations to modern use by R.D.Keys/NA4G. This work was part of a series of HomeBrew construction articles by NA4G on early amateur radio designs for the Raleigh Amateur Radio Society HomeBrew Special Interest Group back about 1992. Permission to reprint provided courtesy QST. The files need to be ungnuzipped and printed on a postscript printer. MAKE SURE YOU HAVE AT LEAST 8 FREE MEGABAYTES ON YOUR HARD DISK IF YOU ARE UNGNUZIPPING ALL AT ONE TIME. Print on dos to a postscript printer as: print filename.ps The gg32text.ps is the normal sized printed text of the work. The gg32big.ps is enlarged print for myopic folks like me, whose arms got short with age. The gg32fig*.ps are the illustrations for the work.
