ARISS - Amateur Radio on the International Space Station @arissintl.bsky.social · 15/08/2026

Still remembering Mike Fincke, KE5AIT (@AstroIronMike) on the subject of his retirement from NASA this week. During a Crew-11 Media Conference he talked about how Amateur Radio on the ISS allows the crew to "bring people with them" and about some of his contacts from onboard.

Wonderful time outside London picking up a couple of new SOTA badges and enjoying the opportunity to play radio with friends new and old. The best thing about this hobby is always the people we enjoy the time with along the way!

Fun morning knocking out a Pasadena area favorite SOTA summit with John before the last day of SuperCon

Two men are smiling outdoors on a sunny day with mountains in the background. The man on the left has gray hair and a short beard, wearing a colorful patterned shirt. The man on the right is wearing a gray hoodie and a dark baseball cap with a round multicolor patch. They’re standing on a dirt trail overlooking a wide valley filled with trees and a distant city, with tall, rugged mountains rising behind them under a clear blue sky.

A foggy morning view from the hills, looking out over a valley blanketed in thick fog. Only the tops of tall buildings rise above the fog in the distance, surrounded by soft blue-gray layers of hills. In the foreground, a few palm trees and green shrubs stand out against the haze, creating a peaceful, dreamlike scene.

Bambu's firmware shenanigans are making me rethink ever recommending one again. They have to backtrack on it, or lose the goodwill of the 3DP community that is "open source but willing to give on value sometimes", which is not an insignificant sector.

The first aurora of 2025 danced in the night sky last night.

Aurora borealis along the horizon with a train track and gravel road in foreground as well as a barn and silo in the middle ground. Captured near Watertown, South Dakota on January 4, 2025.

Fippin' the breakers is the easiest way to find local RFI - or to find out it's not local. When doing so, remember to check your radio power supply too, especially if it's of the switching type. Helped a ham in the neighborhood hunting RFI for him to realize it was the radio switching power supply.

Last day to order a SotaCAT for the year! Get WiFi control, click-to-tune spotting, and SotaMAT integration on your KX2/KX3. We have a few in stock still; any in-stock orders today will ship tomorrow, then we're taking the holidays off. store.invertedlabs.com

🎶 Christmas time is here 🎶 c/o gpt: Receivers strain to hear But noise is oh so near Glowing reindeer on the lawn Make pure reception disappear I tune and adjust my knobs To find that perfect tone Yet flick’ring bulbs and singing shrubs Turn clear bands into drone Oh, static noise is here...

Screenshot of my websdr receiver here in Seattle showing 0-30MHz with a ton of radio noise across the whole spectrum, presumably from local christmas decorations.

For the past year or so, I've been working with @ab6d.bsky.social to turn his SotaCAT design and concept into a ready-to-buy hardware design. After a couple of pre-order rounds and testing, today I opened the web store for general SotaCAT consumption. So what is SotaCAT exactly?

SotaCAT, a small orange elongated cube, is plugged into the side panel of an Elecraft KX3 amateur radio transceiver.

Beautiful start to the morning in Western Washington #wawx

This picture captures the stunning view of Mount Rainier and Lake Washington during sunrise. The lake in the foreground is calm, with soft ripples reflecting the warm light of the sky. The shoreline beyond the water is lined with dense, dark trees, partially obscured by a thin layer of mist rising in the early or late hours of the day.

Mount Rainier stands majestically in the distance, its snow-covered peak glowing faintly against the warm tones of the sky. The sky itself is a breathtaking palette of orange, pink, and red, with streaky clouds stretching across it, creating a sense of depth and tranquility. The overall mood is serene and awe-inspiring, highlighting the beauty of the natural landscape.

Nice quick #hamradio Summits on the Air activation today before the bomb cyclone hits late this afternoon. #SOTA

I am outdoors in a forested area, sitting on the ground and smiling at the camera. I am wearing a puffy blue jacket and have some equipment in front of them, including a notebook and a small case with, with an Elecraft KX2 on my left knee. Next to me is a fluffy white and black dog is sitting, looking off into the distance. The background is lush with mossy trees, ferns, and fallen leaves, creating a peaceful, natural setting.

The image shows a fluffy white and black dog sitting on the forest floor, looking at the camera with a curious expression. In the foreground, there is a close-up view of a small black electronic device, possibly a portable radio or communication device, held by someone whose knee is visible. The device has a digital display showing numbers and various dials and switches. The ground is covered with brown leaves, green moss, and ferns, adding to the forest setting.

Past 24 h with the amazing PDSDR, which monitors 16 FT8 frequencies simultaneously. Eventually I will improve the antenna and make other adjustments to hopefully rival the success @k5em.bsky.social has with his setup.

Continuing discussing these funny shapes in my waterfall from the other site. Sometimes when looking at HF waterfalls, we see these funny blips that change frequency quickly and make shapes that looks like tilted "S"s or some have said fishhooks. What are they?

An image of a spectrogram, which is a visual representation of the spectrum of frequencies of a signal as it varies with time. The top part of the image shows a waveform or frequency spectrum in a green line graph, with frequency peaks marked. The bottom part of the image consists of a heat map in shades of blue, green, yellow, and red, representing the intensity of various frequencies over time. Brighter colors indicate stronger signals, while darker areas represent weaker signals or noise. Most of the signals in the waterfall are more or less straight lines, but some signals, mostly between 26.8 and 27.8 megahertz, change frequency rapidly with time. The imprints they make on the waterfall have been called "S"s or "Fish hooks" because of their shapes.
