Saint Andrew's Student Among 11 Selected to Speak to Astronaut Aboard ISS:
by bocaratontribune.com on November 12, 2017
From aboard the International Space Station (ISS) to the South Florida Science Museum and Aquarium, connection between an astronaut in space and 11 lucky Palm Beach County students was established on Monday, Nov. 6 in West Palm Beach. The 11 students from different PBC elementary schools were winners of an essay contest where students had to write about a question they would ask an astronaut. The communication was made possible by ARISS, the Amateur Radio on the International Space Station, which provided students with an exciting interaction with crew members aboard the ISS in a live talkback. Students, students’ families, museum attendees and the press all patiently glued their eyes to a nearby monitor showing a live global map of ISS’ location. The students only had an eight minute window to ask their questions to Italian astronaut Paolo Nespoli as the ISS sped at a rate of 17,600 mph within the radius of communication. Questions from students were planned and approved and sent to Nespoli weeks prior to ensure each student would be able to ask their question.

Hurricanes Shine Light on Emergency Communications:
by WIA on November 12, 2017
The Atlantic hurricane disasters this year left more than 260 dead with 300 billion dollars in damages, making them the costliest ever. There were three main hurricanes and two others. Hurricane Harvey was the costliest tropical cyclone on record. The weather system was tracked through the Caribbean as it weakened, then intensified to a Category 4 as it hit the US State of Texas. Hurricane Irma inundated Barbuda and Puerto Rico, before moving to Florida Keys in the US. While Hurricane Maria, regarded as the worst natural disaster on record in Dominica, also caused catastrophic damage and a major humanitarian crisis in Puerto Rico. The Federal Communication Commission (FCC) chairman, Ajit Pai, spent two days in Puerto Rico during which he recognised Amateur Radio volunteers in praising those who turned out to help. The FCC had earlier granted the ARRL’s request to waive current Amateur Radio rules to permit data transmissions at a higher symbol rate in order to facilitate hurricane relief communications A string of other Caribbean islands, including the British Virgin Islands, Turks and Caicos, Cuba, and Saint Martin, have been affected. Attention to the role of Amateur Radio has been drawn in comments on International Disaster Reduction Day (October 13), by Caribbean Telecommunications Union Secretary-General Bernadette Lewis who described Amateur Radio as a "bedrock of sustained communications" during emergencies. She spoke as part of a panel on emergency telecommunications during the International Telecommunication Union (ITU) World Telecommunication Development Conference 2017 (WTDC-17), in Buenos Aires, Argentina. Her clear message was to cultivate "a new and younger generation of radio amateurs" to carry out continue provision of emergency communications. From Trinidad and Tobago, Ms Lewis said: "Amateur Radio has been a staple, and it is because of…the Amateur Radio operators in the region that we get a lot of the information that we need."

With Ham Radios and GoPro Cameras, Hobart Students Track Weather Balloons:
by chicagotribune.com on November 11, 2017
The sun poked through the clouds just as the countdown began on the 30-yard line at the Hobart football stadium. Hobart High engineering students checked and made last minute adjustments on their weather balloons, nicknamed Genesis and Exodus, as the helium-filled orbs bobbed in the gusty air. Within an hour Thursday, both balloons were cruising near Nappanee on a course toward Ohio. Each balloon carried an antenna so the licensed ham radio operators Mark Skowronski, of St. John, and Chuck Hill, of Valparaiso, could track it in real time. The balloons also were equipped with a GoPro Hero 3 and a 360 HD camera to record their flights.

Mendocino County Sheriff Examines Lessons Learned from Redwood Valley Fire:
by pressdemocrat.com on November 11, 2017
A month after the Redwood Valley fire took nine lives and destroyed 313 homes in Mendocino County, Sheriff Tom Allman identified several actions Thursday to improve the county’s capacity to warn residents of future fires. The suggestions came during a news conference to recount emergency response efforts, in minute-by-minute detail, during the first 12 hours of the blaze, starting from the first call at 11:34 p.m. Oct. 8 in Potter Valley. An hour later, dispatchers received their first emergency call about fires in neighboring Redwood Valley, to the west. “We’re going to document this as well as possible because if we don’t remember history, certainly we will repeat history,” Allman said to a small crowd in the county supervisors’ chambers in Ukiah. “And we don’t want in 50 years for this fire to occur again.” Allman also noted decadesold technology -- ham radio -- was instrumental in relaying emergency information when land and cellphone lines went down around the fire-affected area.

How NASA Scientists are Tracking Solar Activity to Look for Weird Behavior:
by newsweek.com on November 11, 2017
The sun had been making headlines recently. In September, NASA announced it had released its biggest solar flare for 12 years. This was pretty unusual considering it is supposedly heading into a period of quiet, where activity on its surface becomes muted -- also known as the solar minimum. Scientists' understanding of the sun is relatively limited. Sitting 93 million miles from Earth, NASA is currently planning a mission to “Touch the Sun,” in which a probe will be sent closer to the surface than any spacecraft before. The mission will explore the sun’s outer atmosphere, making observations that should help researchers better understand the workings of our star. What we do know is that the sun operates on 11-year cycles, where activity peaks and wanes. The solar minimum is the period when fewer sunspots (active regions on the surface) appear, while the solar maximum is when most sunspots are recorded. The last solar minimum was in 2008.

Say 'NO' to Parity, and 'YES' to Freedom:
by Russell W. Brill (KN6SD) on November 11, 2017
Homeowners and Citizens need alternatives to cellular phones. Did you know In the Santa Rosa/Napa fires over 80 cell phone towers burned leaving people with no communications. This is where Amateur, Citizens Band, FRS, and GMRS radio steps in to provide a communications path for the public.

Propagation Forecast Bulletin #45 de K7RA:
by W1AW Bulletin via the ARRL on November 10, 2017
No sunspots are visible so far in November, and as of November 9 we have seen nine days of blank Sun. But the past few days had strong geomagnetic activity, with planetary A index on November 7-9 at 36, 47 and 20, and so far on early November 10, at 21. 28 is the predicted planetary A index for November 10.

Amateur Radio Enthusiasts Invited to HamJam 2017:
by northfulton.com on November 10, 2017
ALPHARETTA, Ga. -- Everyone interested in amateur radio, wireless technology and STEM fields is encouraged to visit this year’s HamJam. Hosted annually by the North Fulton Amateur Radio League, HamJam is an opportunity to learn more about ham radio and hear from some of the biggest names in the field. And as their slogan says, “It’s all about the youth.” While admission is free, all proceeds from donations or the raffle will go directly to youth scholarships and educational outreach programs. Some of the benefiting groups and activities include the Girl Scout Super STEM Expo, Atlanta Maker Faire exhibit and American Radio Relay League Teachers Institute on Wireless Technology. “It’s a great hobby,” said North Fulton Amateur Radio League spokesman John Kludt. “It’s a real and fun way to get into the world of electronics and communication… I’ve been in it for 55 years, and there’s always something new to learn, something different, and a great way to augment the STEM curriculum.”

On Air, in Thiruvananthapuram:
by thehindu.com on November 10, 2017
“VU2LVJ this is VU3ZFD/VU2CLU signing off. 73.” Vishnu Prasad, a young electronics engineer whose radio call sign is VU3ZFD, concluded the demo radio conversation he had with Lesley Paul (VU2LVJ) residing at Peroorkada. 73 is the old telegraph code for ‘best regards’, while 88 is for ‘hugs and kisses’! Vishnu switches off the transceiver at the HAM/Amateur radio club (VU2CLU) inside Kerala Science and Technology museum and we go back to join his fellow HAMs of Trivandrum Amateur Radio Society (TARS) who are hard at work, cutting and soldering copper pipes to make a slim-jim antenna used for very high frequency (VHF) communication.

When All Else Fails, South FL Emergency Personnel Use Radio To Communicate:
by wlrn.org on November 9, 2017
The ability to communicate during emergencies, like Hurricane Irma , is critical. When phones and the internet go down, there’s something else South Florida emergency operations centers, or EOC’s, can turn to: amateur radio operators. It’s sometimes referred to as "ham" radio, and the operators are sometimes called “hams.” In Broward County, there are ham radio antennas mounted on all of the hurricane shelters and some of the hospitals, ready to be activated. There’s also a room full of ham radios at the Broward County EOC. Jeff Stahl, coordinator for Broward County’s amateur radio emergency services, recently spoke with WLRN’s Peter Haden about the county's communications plan “when all else fails.”

Bitcoin and Weak Frequency Signals: Bypassing Network Censorship With Radio
by news.bitcoin.com on November 9, 2017
Bitcoin is a fascinating network of verification nodes all working together to secure the blockchain, and its tethered sets of consensus proofs. At the moment, the network is pretty secure, but there are concerns it can be attacked in the future or blocked by things like firewalls, ISP gateways, governments, and telecommunication monopolies. During the scaling conference this past weekend, researchers Nick Szabo and Elaine Ou explain how the Bitcoin network could be broadcasted utilizing “Weak-Signal-Propagation” through radio broadcasts. The two researchers are currently testing and developing the radio-based platform. Weak signal radio communications started coming to life around 2008 when the developer Joe Taylor open sourced “Whisper,” a weak signal propagation reporter. Whisper is a computer program that tethers weak signal radio broadcasts between amateur radio users. To propagate the Bitcoin network using similar technology, Szabo explains the goals are long range broadcasts with a relationship tied to the radio community.
