Propagasi (Jilid 2) Propagasi masih terbagi lagi dalam siklus tahunan dan siklus 10 tahunan. Saat ini kita bahas tentang propagasi yang dapat dilihat secara real time melalui: http://www.hamqsl.com/solar.html dimana disana kita disuguhkan berupa data yang sudah demikian terstruktur. Namun data yang disuguhkan disana lebih terfokus pada propagasi di Eropa. Nah …

Propagasi (difokuskan pengaruh pada band 180 ~ 10m band) Jadi apa yang disebut propagasi? Adalah lapisan udara pada atsmosfer yang selalu berubah keadaan suhunya karena pengaruh peredaran matahari (inklinasi dan deklinasi) ini faktor pengaruh internal, sedangkan faktor pengaruh external dapat dipicu oleh sebab dari ruang angkasa, diantaranya badai matahari, komet yang melintas. …

http://www.dxuniversity.com/dxing/weeklydx.php?id=20 Using Propagation to Your Advantage by Wayne Mills, N7NG We all experience variations in propagation, no matter where we are located. Of course, some areas have much better propagation to areas of greater interest. Topband on the East Coast is a good example. More countries are workable with relatively …

In other words, this value informs us on solar winds reaching our planet and their influence on creating HF propagation conditions. For this measurement, the …

http://k6tu.net/ PROPAGATION FOR CONTEST & DX STRATEGY Quick Tour K6TU.NET generates predictions using the VOACAP engine automated by software developed by Stu K6TU. The idea behind K6TU.NET was to remove the learning curve behind VOACAP and at the same time, automate the generation of enough propagation predictions to enable their use as …
