Foundations of Amateur Radio #150:
by Onno VK6FLAB on April 20, 2018
Last week during F-troop something very interesting happened. If you're not familiar with F-troop, it's a weekly net for new and returning amateurs and every Saturday we welcome callers to the one hour net to discuss anything and everything amateur radio. It's been going for about seven or so years, about as long as I have been making this weekly contribution to the hobby.

Air Waves at the Seaside for Radio Enthusiasts:
by shropshirestar.com on April 20, 2018
Members of Telford and District Amateur Radio Society will set up a radio station on the Welsh coast to join a global celebration of the birthday of Guglielmo Marconi, who was born on April 25,1874, and is credited with the invention of radio as we know it today. Club secretary John Humphreys, call sign M0JZH, of Wellington, said: “We cannot hope to make our antennas as big as Marconi's, but this year our wire will be 80 metres end-to-end and handmade by club members which we will set up in a big field alongside the appropriately named Marconi Bungalows road in Tywyn for this Saturday, April 21.

In the Information Age, Radio Retains Its Relevance:
by echoak.com on April 20, 2018
Alaskans have ridden high on the 21st-century wave of information technology -- a dramatic tidal shift in the way we live and work. Most of us these days would feel somewhat incomplete without our iPhones, internet, cable and streaming video. But another mode of communication, radio, has stood the test of time. It is as relevant today as it was in the 1920s when the Territory of Alaska’s first commercial stations were established: KGBU in Ketchikan and KFQD in Anchorage. And as more stations came on the air in the 1940s -- KFAR in Fairbanks and KENI in Anchorage, colorful personalities began to emerge. Fairbanks’ station KFAR, for example, had two creative geniuses -- Ed Stevens and Ruben Gaines -- who simulated “live” coverage of baseball games. Their play-by-play announcing made it sound as if the coverage were live, which would have been impossible because back then there were no satellites. The pair received information about the game ahead of time by telephone and teletype. With crowd-cheering sound effects, as well as tapping a screwdriver head on a piece of board to simulate the sound of balls being hit by the bat, they made the games sound real -- pitch by pitch, inning by inning. Broadcaster Genie Chance, on what was then 550 AM KENI, remained on the air for more than 35 continuous hours following the quake, with the station running on a backup generator and a damaged transmitter. Ham radio operators across the state relayed important information for rescue coordination during the hours and days to follow. Today they continue to play a critically important role in statewide emergency response and coordination.

Today's Strange Sun: Cycle 24 Stays Weird:
by hudsonvalleyone.com on April 20, 2018
No question: The Sun has been behaving very oddly. First we had a drawn-out cycle, number 23, whose sunspot “minimum” was deeper and more free of spots than any that we’ve observed this past century. When the new cycle number 24 finally began in 2008, nearly two years behind schedule, solar experts wondered if the odd behavior would continue. “If the upcoming solar max of cycle 24 is normal or robust, and especially if an El Niño follows it two years later (as often happens), then the middle of this decade will be the hottest period since humans arrived on Earth. However, if the upcoming maximum is wimpy, as most solar researchers expect, or if the Sun is now entering an extended period of low activity with another deep minimum to follow, that is the best thing it could possibly do for us. Such a scenario would mitigate climate change. Essentially, the Sun has been buying us time.”

Radio Ham in Canada to Gain Access to New 5 MHz Allocation with 100 W ERP:
by The ARRL Letter on April 19, 2018
Radio Amateurs in Canada are poised to join those in several other nations around the world who have access to a new 60-meter band, 5351.5 - 5366.5 kHz, as agreed upon at World Radiocommunication Conference 2015 (WRC-15), but with a maximum power of 100 W effective radiated power (ERP). The updated Canadian Table of Frequency Allocations includes the new allocation, although radio amateurs have not yet been authorized to use it. Canada's radio amateurs will also retain the four Amateur Radio channels that do not fall within the new allocation. These spot frequencies have been authorized under a footnote to the Table since 2014, on a secondary, non-interference basis.
