/////////////////////////////////////////// Radio Amateurs Take Part in Black Bear Festival: Posted: 03 Jun 2016 05:52 PM PDT http://www.eham.net/articles/36903 For the sixth year, hams from the Bayouland Emergency Amateur Radio Service amateur radio club operated a special event station from the banks of Bayou Teche in Franklin. The station is a public event that helps spread the news via ham radio concerning the activities at the Black Bear Festival. Ham radio operators from nine or 10 different states and Canada called in to talk and await a special QSL card that will be sent to each one. /////////////////////////////////////////// Tinylily Mini: Morse Code: Paris In the Mint Box: Posted: 03 Jun 2016 05:51 PM PDT http://www.eham.net/articles/36902 [Rob Bailey] likes to build things and he likes ham radio. We are guessing he likes mints too since he's been known to jam things into Altoids tins. He had been thinking about building a code practice oscillator in a Altoids Smalls tin, but wasn't sure he could squeeze an Arduino Pro Mini in there too. Then he found the TinyLily Mini. The rest is history, as they say, and 1CPO was born. The TinyLily Mini is a circular-shaped Arduino (see right) about the size of a US dime. most of the pads are arranged around the circle and there is a small header that takes a USB programmer. A small rechargeable battery can run the device for a long time. If you've ever written Morse code software, one challenge is to compute the actual sending speed in words per minute (WPM). If you are doing a serial port, for example, the speed is easy because the sent elements are the same length. However, with Morse code, some things are very short (like an E, for example) and some are much longer (like a zero). In fact, the code tries to reflect the frequency certain letters occur. E is the shortest character and the most common in English texts. You might think [Samuel Morse] was responsible for this, but his original code was only numbers. The idea is you would get numbers and look them up in a code book. Presumably, some of the codes would have been single letters forming an early coding like ASCII, Baudot, or EBCDIC. [Alfred Vail] expanded the system to include letters and other characters and assigned lengths based on the examination of type cases at the local newspaper. That code also used dots, dashes, and long dashes, but it is almost recognizable as the Morse code in use today. /////////////////////////////////////////// Massive Rehearsal Planned for Northwest Mega-Quake, Tsunami: Posted: 03 Jun 2016 05:50 PM PDT http://www.eham.net/articles/36901 PORTLAND, Ore. (AP) - Imagine a devastating earthquake and tsunami have cut off Pacific Northwest coastal communities. Phone and internet service have collapsed. Ham radio operators living on the stricken coast fire up their radios, contact emergency managers and report on the magnitude of the disaster so that no time is wasted in saving lives. This is the kind of scenario that will be rehearsed during the second week of June in a massive earthquake and tsunami readiness drill that has been developed by the U.S. government, the military, and state and local emergency managers over the past few years to test their readiness for what - when it strikes - will likely be the nation's worst natural calamity. The June 7-10 exercise is called Cascadia Rising. It is named after the Cascadia Subduction Zone - a 600-mile-long fault just off the coast that runs from Northern California to British Columbia. "This is the largest exercise ever for a Cascadia break," said Lt. Col. Clayton Braun of the Washington State National Guard. Braun has been a key planner of the doomsday drill, which is being overseen by the Federal Emergency Management Agency. Federal officials say about 20,000 people will be involved in the disaster drill, representing various federal agencies, the U.S. military, state and local emergency response managers across the Pacific Northwest, Native American tribes and emergency management officials in British Columbia. One main goal of the exercise is to test how well they will work together to minimize loss of life and damages when a mega-quake rips along the Cascadia Subduction Zone and unleashes a killer tsunami. /////////////////////////////////////////// Amateurlogic 91 is Released: Posted: 03 Jun 2016 05:53 PM PDT http://www.eham.net/articles/36900 AmateurLogic 91: Hamvention 2016 - Part 1, 'Party on Darth' has been released.
