This is an introduction to Meteorscatter Amateur Radio: what it is; how it works; what one needs to successfully do meteorscatter VHF communications. The presentation links to actual recorded meteorscatter contacts with video/audio YouTube links. Meteorscatter references and source material is included to give licenced amateur radio operators a good start in this unusual radio medium. The presentation will assist shortwave enthusiasts and those generally interested in meteors and radio. – PowerPoint PPT presentation
