Rolf’s LED backlight mod for Sony ICF-SW35

Many thanks to SWLing Post contributor, Rolf Snijder, who writes:

This is a simple LED backlight modification for the Sony ICF-SW35.

Simply add a 120K resistor and a bright LED:

When you push the backlight switch, the light stays on.

When radio is turned off, the light goes off–then push light switch and backlight will stay on for 15 seconds or so.

Thanks for sharing this simple mod, Rolf!

Ed spots a Heathkit HW-101 in The Royal Tenennbaums

Many thanks to SWLing Post contributor, Ed, who writes:

I was in my corner bar last night in Philadelphia where “The Royal Tenennbaums” (2001) was playing on the projection screen. I wasn’t really watching it, but a scene showing a Heathkit HW-101 HF transceiver suddenly caught my eye. When I told my my drinking buddy, Richard, “That’s a Heathkit HW-101!” He called me a hopeless geek.

I’m not sure what tuner is on the shelf below it, but maybe a SWLing blog reader can identify it.

Great job spotting the HW-101, Ed!

Ed actually sent this tip to me several months ago, but it got buried in my drafts folder–sorry about that!

Boca Raton Essay Winners Chat with Astronauts on Board Space Station:

eHam.net News - Palm Beach County students who won an essay contest got the chance to speak to astronauts out of this world, literally. About a dozen students from Palm Beach County got to speak live with an orbiting astronaut on board the International Space Station. The South Florida Science Center and Aquarium recently hosted the ARISS (Amateur Radio on board the International Space Station) event. Students in grades 2-12 from public, private and home schools wrote a 250-word essay on the topic: "If you had a chance to ask an astronaut any question, what would it be and why?" Two winners attended Boca Raton schools. Paolo Nespoli, the Italian astronaut on board the ISS, answered the twelve winning questions while the space station orbited over the Georgia/Florida border. The communication was done through ham radio, thanks to one of the largest amateur radio organizations in the country that works with the Science Center. Traveling at 17,000-miles-per-hour 250 miles up in the air, the ISS was only in radio contact for eight minutes.

ICON & GOLD Teaming Up to Explore Earth's Interface to Space:

eHam.net News - Like Earth, space has weather. Except instead of swirling winds and downpours of precipitation, space weather is defined by shifting electric and magnetic fields and rains of charged particles. At the very beginning of space, starting just 60 miles above Earth's surface, there's a layer of the atmosphere that shifts and changes in concert with both types of weather. Above the ozone layer, the ionosphere is a part of Earth's atmosphere where particles have been cooked into a sea of electrically-charged electrons and ions by the Sun's radiation. The ionosphere is comingled with the very highest -- and quite thin -- layers of Earth's neutral upper atmosphere, making this region an area that is constantly in flux undergoing the push-and-pull between Earth's conditions and those in space. Increasingly, these layers of near-Earth space are part of the human domain, as it's home not only to astronauts, but to radio signals used to guide airplanes and ships, and satellites that provide our communications and GPS systems. Understanding the fundamental processes that govern our upper atmosphere and ionosphere is crucial to improve situational awareness that helps protect astronauts, spacecraft and humans on the ground. Two new NASA missions are teaming up to explore this little-understood area that's close to home but historically hard to observe. The Global-scale Observations of the Limb and Disk, or GOLD, instrument launches aboard a commercial communications satellite in January 2018, and the Ionospheric Connection Explorer, or ICON, spacecraft launches later in 2018. Together, they will provide the most comprehensive observations of the ionosphere we've ever had. The two missions provide distinct but complementary perspectives: ICON, in low-Earth orbit, flies directly through and just above regions of interest, capturing detailed remote and in situ data on the forces that shape this area. GOLD, in geostationary orbit over the Western Hemisphere, will build up a full-disk view of the ionosphere and upper atmosphere every half hour, providing detailed large-scale measurements of related processes -- a cadence which makes it the first mission to be able to monitor the true weather of the upper atmosphere, rather than the longer cycles of its climate. GOLD is also able to focus in on a tighter region and scan more quickly, to complement additional research plans as needed.
