A simple application to assist ham radio operators in everyday HF propagation prediction.The application calculates MUF (Maximum Usable Frequency) and LUF (Lowest Usable Frequency) to any location in the world based on SSN data. The application is based on MicroMUF, developed in 1984 by Raymond Fricker from BBC External Service. Although the algorithms used in MicroMUF have some limitations compared to other more advanced algorithms (like IONCAP), the calculations are very accurate for everyday use in the HF range (2-30Mhz). The application contains the complete and updated DXCC countries list, so that you do not have to enter latitude/longitude but type directly the DXCC prefix or country name for the transmitter and receiver location, while the SSN is retrieved automatically from NOAA site if required. Most often used propagation paths can be saved so that a prediction can run on them later.There is no limit to the number of paths stored into the application. 一个简单的应用程序,帮助运营商在日常HF传播prediction.The应用的业余无线电计算最大可用频率(MUF)和最低可用频率(LUF)SSN数据的基础上在世界上的任何位置。 该应用程序的基础上,由Raymond弗里克于1984年开发从BBC的外部服务MicroMUF。 虽然在MicroMUF所用的算法相比,其他更先进的算法(如IONCAP)有一定的局限性,计算是非常精确的日常使用在高频范围内(2-30Mhz的)。 该应用程序包含完整和最新的的DXCC国家列表,这样你就没有进入纬度/经度但类型直接DXCC前缀或国家名称为发射机和接收机的位置,而SSN如果需要从国家海洋和大气局网站自动检索。 最经常使用的传播路径可以被保存,所以,可以运行在他们的预测later.There是存储在应用程序的路径的数目没有限制。 更多
