A pulse of UV and X-radiation from the flare ionized the top of Earth's atmosphere. This, in turn, altered the normal propagation of shortwave radio transmissions on the dayside of our planet. People who might have noticed blackouts, fades, and other transmission irregularities include aviators, mariners, and ham radio amateurs. Stronger flares and CMEs could be in the offing, however, as the sunspot continues to grow and turns toward Earth. To exist, Amateur Radio must have access to the radio frequency spectrum otherwise our equipment would be useless, like a boat without water. Soon several other countries in the world also followed suit. When the IARU was founded it offered protection for amateur radio and could liaise with the ITU. Trustees will have absolute discretion how funds for the current and for future major relief situations are to be utilised. This is an open and honest initiative from Council to establish a fund for the current and for future major relief situations to assist in extra ordinary circumstances and not ordinary charity circumstances. The rates are based on the complete supply of material in Jpeg unless otherwise negotiated. Radio Amateurs of Canada has announced an award for radio amateurs and short-wave listeners that involves using HF radio to track the 150-day Canada C3 voyage of the Polar Prince from Toronto, Ontario, to Victoria, British Columbia, via the Northwest Passage. Carl Sagan and Frank Drake used this type of transmitter at Arecibo, Puerto Rico, to send the most powerful radio signal ever from Earth into space. The signal was travelling in the direction of the constellation of Hercules, which happened to be overhead at the time. When the SKA comes on stream in 2024 then radio astronomy can also boast the largest antenna system in the world. The super-fast stars were discovered about a decade ago, and only 20 had been verified prior to the latest breakthrough, which is necessary if we are to understand if their speeds are determined by collisions near the black hole at the centre of our galaxy, or perhaps some other violent gravitational encounter, or the effect of dark matter. The ESA chose to use an artificial neural network, which is software designed to mimic how our brain works, and after combining all these data, they found that six stars can be traced back to the Galactic Centre, all with velocities above 360 km per second. Using homebuilt equipment or operating as a portable/field station and using temporary antennas is encouraged, but is not a requirement. Frequency: The first hour is limited to the 40 m band only, the remaining two hours the contest- ers are free to use any HF (non-WARC) band as they see fit.
