I guess what they're hoping for, is a sign-on from the carriers to contribute to a national database linking MACs to clients. In the future, they might hope to make enforcement easier by having quiet drones fly around at night checking on everyone. Now be good y'all

All money raised goes to the Cancer Council towards cancer research.You can book online at:http://www.eventbrite.com/e/back-to-the-future-trivia-tickets-18034206798?aff=efbeventDave, if you're not doing anything and want to get involved, we'd love for you to join us.

If you're really going to have a go at this with something you'll have to be prepared break things often and buy another probably just to work out how to dump the firmware and spend maybe days reading the disassembled code.

content: Very good video. Some nice equipment in here. Was that an FT-101E? And an AWA FISK radio?Most of the video was absolutely correct. The tiny electronics community in Australia is very innovative.But the state of electronics in this country is in a deep recession. Most electronics manufacturers are gone - forever. Automotive innovation and manufacturing are almost gone. R & D is on the decline. It's true, the vast majority of Australians are dick heads when it comes to knowing anything about electronics, or even basic electricity. Most of the fault is our government who abandoned the "Knowledge Nation" paradigm for the short term gain "Servant Mining Nation" paradigm.Australia's government does not care about electronics. The post of Minister for Science and Technology was abandoned by the government a couple of years back. We are a commodity country - we dig up dirt and polluting coal and sell it to communist China who converts the dirt into shoddy products and sell them back to us at a higher price. We now have a$1 trillion foreign debtfor a country of only 24 million people. Now the demand and price of iron ore and coal has plummeted, we have nothing else to offer that can fix our balance of payments problem and our Australian dollar is free falling. 100% of the blame is the POLITICIANS who were mostly trained as lawyers who know zero about electronics or the wealth it can create. Even Tony Abbott boasted not long ago he does not know how to use a laptop computer. These clowns have put all our eggs in one basket and now the basket has dropped.There are a lot of famous faces on that video. We need some of them in senior positions in government to take the place of some self serving lawyers.Dave for Prime Minister? His election opening speech might begin with "Hi. Today we will do a tear down of our education system for aspiring electronic engineers."
