An Ultra Low Distortion Audio Test Oscillator

This project was published in the March 2010 issue of the Australian magazine "Amateur Radio", and uses a unique circuit and cheap readily available components to acheive laboratory grade performance. :-)


Note that the two Encapsulated Post Script files (EPS) for the printed circuit boards should be opened in monochrome at 300dpi or greater in Paint Shop Pro, Adobe Photoshop etc.etc.
