20 Years of Amateur Radio on the International Space Station

Amateur radio achieved 20 years of continuous operations on the International Space Station in December and celebrated with a slow-scan television (SSTV) event at the end of the month. The ISS crew set up automated SSTV transmissions of 12 different images and multitudes of Earth stations received them.

I managed to copy 7 of the 12, plus the very bottom of an eighth, using my makeshift setup: an iPhone with the Black Cat SSTV app held at the speaker of my Kenwood TH-F6A handheld. I used a rooftop 7/8-wavelength 2-meter vertical for my first attempts, which gives good results except for some noise banding. My best images came with the Arrow antenna I use for all satellites.

Like many other listeners, I uploaded my image files to the ARISS SSTV Gallery, then requested a certificate of accomplishment. It arrived promptly today.


The first successful ARISS contact with a school happened December 21, 2000. Since then, astronauts have made more than 1300 school contacts all over the world.

Distance Record on AO-92

On 2019-02-20 at 13:08Z, EB1AO and I completed a 4,936-km QSO between IN52pe and FN43rg, setting a distance record for the U/v repeater on AO-92. It was a -11° pass — Celsius (12°F… brrr). Really, it was a 1° pass — maximum elevation at my end. Jose's map tells the story, though the time reported is his AOS , not QSO time. We both recorded the contact. Mine is in Dropbox: eb1ao_AO-92.wav . Thanks EB1AO. Thanks AMSAT-NA . UPDATE: Our record was surpassed by F4DXV and VE1VOX, who added 75 km to the distance, in August 2020.

Bird of the Year Poses Typographical Challenge

The American Birding Association's selection of the ʻiʻiwi as its 2018 Bird of the Year poses a typographical challenge: What to do about the ʻokina? That "single quote" at its start, and right between the i's, is one of two Hawaiian diacritical marks . It denotes a glottal stop, a quick throat-catch like that in uh-oh, so ʻiʻiwi is pronounced ee-EEvee . The ʻokina appears once in the main heading of the Bird of the Year page, but is omitted throughout Nate Swick's explanation of why the honeycreeper was chosen. This inconsistency is avoidable and the omission is undesirable. The ʻokina is not optional punctuation but a purposeful letter. The ABA isn't awkward alone. The Birds of North America account at the Cornell Lab of Ornithology spells ʻiʻiwi three ways (unique treatments in heading and citation, main text, and image caption). The American Bird Conservancy gives this bird two marks but resorts to the straight quote (prime) rather than employing

One White Heron

A 2-ounce packet of an organic black tea, Dubliner's Breakfast, from White Heron Tea of Portsmouth, New Hampshire, found its way into my Christmas stocking. Santa knows. I inferred this would be a hearty, rich brew, that would brace me for morning. Dubliners are Irish, no? Instead, I tasted a nuanced, fruity cup with less kick than anticipated or desired. The packet went into the afternoon collection, taking an honored place in the rotation especially when the mood was more cerebral than kinetic. Three and a half stars.
