Radio Waves: Stories Making Waves in the World of Radio<\/h2>\n

Welcome to the SWLing Post\u2019s<\/em> Radio Waves<\/em>, a collection of links to interesting stories making waves in the world of radio. <\/strong>Enjoy!<\/strong><\/p>\n

Many thanks to SWLing Post<\/em> contributors Richard Cuff, Jason Shultz, David Iurescia, Tracy Wood, and Carlos Latuff for the following tips:<\/strong><\/p>\n

During a once-in-centuries eclipse, CWRU radio club ran a cross-country experiment\u2014and found a surprise overhead | CWRU Newsroom | Case Western Reserve University (CWRU Newsroom | Case Western Reserve University)<\/a><\/h2>\n

Study coauthored by students from high school to grad school finds the moon\u2019s shadow took a different path overhead than on the ground<\/p>\n

Minutes after totality swept past Cleveland on April 8, 2024, Laura Schwartz and Maris Usis leaned over a laptop on the roof of Case Western Reserve University\u2019s Glennan Building. Data from receivers hundreds of miles away were streaming in.<\/p>\n

Then a small change appeared in the recorded radio signal.<\/p>\n

\u201cIt was very exciting,\u201d recalled Usis (CWR \u201924; GRS \u201925, electrical engineering). \u201cAt the very least, it was an early indication that our experiment may have worked.\u201d<\/p>\n

Nearby, David Kazdan, MD, PhD (GRS \u201992, biomedical engineering), watched the graphs take shape.<\/p>\n

\u201cIt really was just a magic moment,\u201d said Kazdan, an adjunct professor at the Case School of Engineering and faculty advisor to the Case Amateur Radio Club, W8EDU.<\/p>\n

Skywave, a free browser player for public KiwiSDRs with a live \u201cstrong signals now\u201d scan (Skywavehf)<\/a><\/h2>\n

This tip was submitted by a developer promoting his AI-created app, and it caught my attention. It\u2019s called skywave (http:\/\/skywavehf.com<\/a>), a free web app that plays public KiwiSDR receivers right in your browser. Press \u201cListen\u201d and it finds the receiver with the best reported signal-to-noise on your frequency, moving to the next one if a Kiwi is full or refuses the connection.<\/p>\n

There\u2019s a searchable list and a map that shades where it\u2019s currently night, which is a nice touch for propagation, and about ten seconds after a receiver starts playing, skywave scans the medium wave and fourteen shortwave broadcast bands, listing the strongest signals it hears, labeled with station names from the EiBi schedule. You get a waterfall with a live spectrum trace and an S-meter, and the AM, SSB, and CW demodulation is done in the developer\u2019s own code, with the Kiwi only sending raw I\/Q.<\/p>\n

Jason has also been considerate of the volunteers who run these receivers: skywave takes at most one listener slot per Kiwi, identifies itself as \u201cskywavehf.com\u201d in the user list, and there\u2019s a page for owners explaining all of this, including how to opt out.<\/p>\n

The developer built it with an AI coding assistant, something he\u2019s upfront about, the code is public on GitHub, and as far as I can tell it\u2019s free, runs no ads, and requires no account. Since these receivers are run by volunteers, do be a good guest and disconnect when you\u2019re finished.<\/p>\n

FEBC Philippines to Conclude Shortwave Broadcasting in 2027 (Febc)<\/a><\/h2>\n

After decades of using shortwave radio to carry the Gospel across geographic boundaries, FEBC Philippines will conclude its shortwave broadcasting operations at its facilities in Iba, Zambales, and Bocaue, Bulacan, effective April 1, 2027.<\/p>\n
