WHEN ALL FAILS AMATEUR RADIO SUCCEEDS
Something has gone terribly wrong. Normal ways of doing things are not working. The fastest way to turn an emergency into a full disaster is to lose communications.
Radio Amateurs understand emergencies. For over 70 years they have provided emergency communications for organisations. When normal ways of communication fail or get overloaded Radio Amateurs will be there.
HAMNET, the National Emergency Communications division of the South African Radio League (SARL), provides communications for emergencies and can mobilise experienced communicators who with their own radio equipment will back up official channels or take over when all else fails.
The SARL represents all Radio Amateurs in South Africa at all levels of Government and through the IARU at the International telecommunications Union.
Radio Amateurs or "Hams" use two-way radio communication to make contact with other radio amateurs all over the world. They are even able to use satellites and on occasion speak with astronauts. Radio Hams can do this from home or while mobile in cars, boats or on foot.
Radio Hams have a full range or communication modes at their disposal. These include plain voice, Morse code, numerous digital computer modes and even graphical modes like television. A licensed radio amateur is able to join in experiments using all these modes.
HAMNET REPORT 2 March 2014
Research has shown that the appearance of more cyclone activity in the Indian Ocean over the past few years is now a fact.
Listening to a presentation on Radio 702 this week, the warming of the Indian Ocean due to Climate Change, is having an effect on not only the appearance but also the intensity of Indian Ocean Cyclones. And to crown it, these cyclones are on the increase!
Over the past 150 years, keeping record of Cyclones has not that accurate but over the past 40 odd years; more accurate records indicate the above.
Cyclones are occurring more regularly and moving further south than ever before. They often affect Madagascar, Reunion and Mauritius. Prior to Cyclone Domoina, there have been cyclones that penetrated the Mozambique coast and well into Mpumalanga, Limpopo and KZN provinces.
The chances are that we may in the not too distant future experience the ‘aftermath’ of Indian Ocean Cyclones moving further south west and influencing rain patterns over our eastern seaboard is quite possible.
Not that we need to batten down the hatches right now, but it is a phenomenon that is on the increase and only time will tell how soon we can expect more inclement weather emanating from cyclones that peter out over land as tropical storms.
On that same subject, man-made and natural disasters are always a heavy price to pay. With more information now available from behind the ‘Bamboo Curtain’ China paid out twice as much to mop up after natural disasters in 2013 as it did in either of the previous two years. These rising costs are partly down to climate change.
Earthquakes, floods, droughts, snow storms and other disasters cost China over 420 billion yuan ($60 billion) according to reliable sources. The costs in 2011 and 2012 were just 260 and 220 billion yuan. From all information gathered, climate change was left its calling card!
Droughts and severe rainfall is on the increase in many parts of China and also an increase in temperatures. This is affecting the country economically as to build more and safer houses are placing a strain on various budgets.
China’s National and Reform Commission is restructuring their outlook on possible disasters and hope to develop a warning system for residents, Provinces and coastal towns in the event of unnatural weather and other events that could endanger the population, infrastructure and Industry!
From local bits of information, Hamnet Western Cape is as usual in full swing with cycle races and other events that need our communication skills. An early call has already gone out for volunteers for the Two Oceans Marathon that traditionally takes place on Easter Saturday.
