Hi, glad you dropped in. Here you will find information of interest to Amateur ("Ham") Radio operators. There are currently sections on VHF and above radio wave propagation, including educational material and a real-time aurora monitoring page; technical and operating information for VHF and above bands; some information about my past and present activities, and various other stuff.
