![]() Therefore the effects particle emission of sunspot activity cause a significantly delayed response on our Ionosphere. Though the EM energy component reaches earth in a matter of minutes, but the particle component takes several days to travel the distance between sun and earth. Furthermore, sunspots release both EM energy as well as sub-atomic particles. The earth's Ionosphere has a huge inertia against quick changes. However, contrary to the popular myth, the "daily SSN" value does not provide much help in short-term forecasting or determining the current state of HF propagation. These numbers when collected over a period of time are very useful for assessing medium and long term trends in expected Ionospheric conditions. Multiple readings from every observatory is collated and processed using an averaging (smoothing) algorithm and presented as the sunspot count for a particular day. ![]() Sunspots are counted throughout the day by several observatories around the world on a daily basis. ![]() In turn, they found that HF communication on earth was influenced by sunspots. Long ago, scientists discovered a correlation between the number of observed sunspots and the density of the Ionosphere on earth. These spots are visible from earth and are called sunspots. This manifests itself as regular eruptions of EM energy and sub-atomic particles from random places on solar surface. Sunspots are visible dark spots which occur on the sun surface on account of continuous thermo-nuclear activity at the solar core. We will briefly review these parameters to attain better clarity and understanding on some of the facts and myths. SSN, SFI and their bearing on HF Propagation.īoth the terms SSN and SFI are solar emission related parameters which are commonly used in context of HF radio propagation. Try to blast out whole rows of space invaders at once as it makes it easier to shoot into a crowd rather than pinpoint each individual ship.Ĭurrent Solar Flux / SSI discussion and propagation trends To ensure you stay alive as long as possible, hide behind the green walls and develop and a run-and-gun mentality. Be careful though, because these ships fire back and as you deplete their numbers, the space invaders get faster and faster until the last remaining ship appears to move at near warp speed. Use the mouse to fire your gun at them and blow each ship to pieces. You are a space ship who must destroy the invading enemy space ships as they descend upon your little 8-bit world. The idea of this game is very simplistic. Whilst waiting for your favorite DX, compete with your fellow Ham Radio friends. Remember this old classic from 1978? Space Invaders is one of the most addicting games that was ever made. Live Time Zone display with 20 Time zones. I will keep informing about the 64-bit version progress here. If you are using HamSphere 3.0 mobile you may want to wait with the iOS11 upgrade until we have made our app compatible with Apples new directive. We will upgrade our app, but we do not have a completion date set yet. It includes the mobile HamSphere 3.0 version. Since Apple decided to drop all 32 bit support in their new iOS11 some 200.000 apps have been made obsolete. ![]() Standard plug-in is now 8 euros and the Moxon antennas have been reduced with about 20%. ![]() We have lowered the Android Mobile plug-in and antennas prices. We have another strong South American contender Miguel, PU2MNQ who is climbing fast in this Q. Ravi VU2RVE fought for his second position over two quarters but had to yield in the last Q, leaving him in third place. Alex, RA9CUH held the position for 2 quarters but were overtaken by Nestor, LW6DC who grabbed the pole position last quarter. If you feel that you have graphical design skills, you can send your rig idea for a fresh 3.0 upgrade to Perhaps your designed skin will be used for the next 3.1 release.Īnother quarter has passed and we notice that we have a top fight between some very skilled ops. Here is an example sent in by Bill 2HS8438 ![]()
