The HF Guidebook
Hello dear reader,
Here you have a great manual, by SGC, which I consider a en excellentintroductory book for anyone getting started on shortwave (HF). Explains lots of basic concepts, from the modulation techniques, equipments, antennas, and so on! It focus on SSB - Single Side Band - which is the most efficient modulation technique that amateurs use.
"Globally, HF-SSB has literally changed the world. For a minimal investment, it has allowed millions of people - often in amazingly remote settings, often in emergency conditions - to reliably bounce clear voice and data signals across a state, across a continent, over an ocean, or around the world. Without satellites, relay stations, cellular nets, stadium sized antennas or huge user fees. Just some fine equipment, a smart operator and nature's own ionosphere make this possible.
For nearly 25 years, the perfection of HF SSB has been the focus and the life of our company. Our efforts have not gone
unnoticed. Today, SGC is a prominent choice of leading corporations, governments, relief agencies, paramilitary
organizations, mariners, aviators,
explorers, and scientists - all over the
world. They trust our engineering and
they value our experience."
