var blurb = "<p> <b>Amateur radio:</b> <br> For some it is making contact with as many people locally and from around the world as possible (QSL you are 5/9). For others it tinkering with gadgets or gizmos, understanding how they work and how to improve or adapt for other uses. For others it is just a hobby to experiment with basic principles of physics, the laws of quantum mechanics or simply merging crazy ideas together to see what happens... <br> <br> Amateur radio can expose you to many things, from working with wood, metal, plastics, hand and power tools to exploring aspects in the fields of chemistry, geology, physics, astronomy, optics, electronics, computing, data networking, audio phonics, video processing, communications, media presentation, logistics, people management and the legal issues that tend to pervade everything you want to do nowadays. </p><p> Life in general does teach you a lot, as long as you can listen, learn and not get hung up on the bad experiences you can get a lot done, understand much about the universe and know first hand how parts of it work. Amateur radio allows the experimenter (good/evil genius) to try new things or repeat known techniques with guidance from elders or knowledgeable people, in person, online or in print, be they alive today or many epochs past. <br> <br> This knowledge combined with a scientific way of thinking (cause and effect) can assist you to overcome almost any obstacles by simply asking questions, thinking through a problem, learning from mistakes and where needed to circumvent human follies, ritual or dogma. Over millennia the human race has misused much of its resources, lost valuable time and missed many opportunities to advance; all because of greed, power and ignorance. We are so smart yet so dumb, but I digress...<br> <br> Amateur radio can be a simple tool to communicate with others or a vehicle to understand how things in the real world work. You could ask; what will 'amateur radio' do for you, or should that be, what can you do for amateur radio? <br> </p><p> <b>About me:</b><br> I've worked in the education, computer and networking industries for over a decade and also in the manufacture and packaging industry of chemical & lubrication products for just as long. I dabble in astronomy and electronic surveillance and I’m currently working in the aero-space industry. I hold no official qualifications apart from my amateur radio license but do have a wide range of experience and know how with a zest to apply and try almost anything... <br> </p> Thanks for visiting my website, everything here I've written from the back-end to the page on display. I promise there is no intentional surreptitous code or activity in use. IP's may be recorded for stats and google ads do their own things. Feedback is always welcome...<br>I hope you find something of interest here...";
