For instance, I spent the past day reading detailed reprints from the NRC and IRCA publications involving Local Sunrise and Sunset DXing, including a review of maps and calculations. Complicating the issue are FCC rules changes which have changed the types of stations and their authorizations. At the moment, I'm looking for software or a web based application that would provide the following information without having to do a lot of manual calculations: 1.) Gray line map showing also the tilt of the earth between solstice and equinox. In other words, a map that provides a real time view of the earth as it really is today. Not a simplistic representation that does not change with the seasons. 2.) The ability to select any two points on earth and see if they are in darkness or light. 3.) Domestically, I'd like a map that shows which areas are operating under sunrise or sunset authorizations. In other words, one that will do the calculations for me. Does such a tool exist? -- 73, Les Rayburn, N1LF Maylene, AL EM63 Member NRC, IRCA, & Medium Wave DX Circle Former CPC Chairman for NRC/IRCA Perseus SDR, SDR-IQ,Funcube Pro, Wellbrooke ALA-1530+ loop, LF Engineering Active Whips, Quantum Phaser, Kiwa Loop, Palstar MW Pre-Selector _______________________________________________ The NRC AM mailing list Questions?
