/////////////////////////////////////////// Ham Operator Team Claims Top Spot in Maine: Posted: 06 Dec 2016 04:02 PM PST http://www.eham.net/articles/38181 An East Boothbay Ham radio team made more contacts than any other team during the American Radio Relay League (ARRL) Field Day June 25. The team, consisting of Al Sirois of East Boothbay, his brother Ron, of Salem, Massachusetts, Will Brinegar of Southport and Ron Scribner of Pittston made more short wave radio contacts than the other 22 Maine teams during the 24-hour test period. The league sponsors the annual field day to prepare amateur short wave radio operators for coordinating emergency communications during an actual disaster. During past catastrophes like the 9/11 terrorist attack, Oklahoma City bombing and Maine Ice Storm, ham radio operators coordinated emergency rescue responses between local, state and federal rescue teams. Sirois hosted the event last summer so other licensed amateur radio operators could test their skills during the worldwide exercise. /////////////////////////////////////////// Ham Operators Participate in NWS Exercise: Posted: 06 Dec 2016 04:01 PM PST http://www.eham.net/articles/38180 Thirteen operators of the WX4PTC amateur radio station at the Peachtree City Weather Forecast Office made 475 contacts with other hams and NWS offices over a 24-hour span last weekend. Operators made contacts with stations from Florida, to California, to Washington, to Maine and most states in between. "Our northernmost contact was a station just west of Edmonton, Alberta and our southernmost was a station in Puerto Rico," according to a participant. Hams made contacts with 40 other NWS offices and the Amateur Headquarters in Newington, Conn. /////////////////////////////////////////// An Amateur Radio Repeater Using an RTL-SDR and a Raspberry Pi: Posted: 06 Dec 2016 04:01 PM PST http://www.eham.net/articles/38179 An amateur radio repeater used to be a complex assemblage of equipment that would easily fill a 19 rack. There would be a receiver and a separate transmitter, usually repurposed from commercial units, a home-made logic unit with a microprocessor to keep an eye on everything, and a hefty set of filters to stop the transmitter output swamping the receiver. Then there would have been an array of power supply units to provide continued working during power outages, probably with an associated bank of lead-acid cells. More recent repeaters have been commercial repeater units. The big radio manufacturers have spotted a market in amateur radio, and particularly as they have each pursued their own digital standards there has been something of an effort to provide repeater equipment to drive sales of digital transceivers. But what if you fancy setting up a simple repeater and you have neither a shed full of old radios or a hotline to the sales department of a large Japanese manufacturer? If you are [Anton Janovsky, ZR6AIC], you make your own low-powered repeater using an RTL-SDR, a low-pass filter, and a Raspberry Pi. /////////////////////////////////////////// Ham Talk Live #42 Hurricane Watch Net: Posted: 06 Dec 2016 03:53 PM PST http://www.eham.net/articles/38178 Coming your way on Ham Talk Live! this Thursday night is Bobby Graves, KB5HAV, the manager of the Hurricane Watch Net.
