GloTEC Ionosphere Data

 KO6BTY and I have been playing with ground and spaced based ionospheric data for the last couple of years. This week, we started looking at the NOAA experimental GloTEC project's data. It's really nice in that it has virtually complete global coverage. Also, it's very up to date. At the time of this writing, it's 16:11 UTC and the most up to date data is from 15:45 UTC. I've used ChatGPT o3-mini to update our data analysis code for the new, to us,  GloTEC format and we're starting to see really interesting results. Below are two videos of maps we've created. The first one is for the maximum height of the F2 layer, also known as hmF2, and important for 20 meter ham radio propagation. The data is from Tuesday evening, 2025/02/12 UTC. The second is of the critical frequency, aka foF2, (the maximum frequency radio signal that will bounce vertically from the F2 layer), for the same time period. You can see the  Equiqtorial Ionization Anomaly (EIA) very clearly ...

Is the Logitech Litra Good For Soldering?

 I came across the Logitech-G shopping site this morning, which was kind of like getting the Christmas Sears Catalog way-back-when: Soooooooo much stuff I don't Need with so much giggling and imaging that yes, I really do need a glowing keyboard. Anyway.  Is anyone using one of these as a bench-top soldering light? They seem like a great form factor for the desk the kid and I share between gaming, work, and radio assembly, but maybe they're not? I've hit the point in my eyes where I need more light, and yes I could get a desklamp from a garage sale... maybe, but this little guy just looks kinda cool.

My first YouTube LiveStreamed POTA Activation

 I made a livestream of my POTA activation from US-4571, Juan Bautista National Historic Trail in San Francisco on YouTube last night! It was pretty fun although the audio mostly didn't work out great. I'll be making notes here and in the video's comments on the QSOs in the vieo over time. (One of the things I learned was that there's no editing or even downloading of YouTube livestreams after the fact.) Here's the video, scroll for more details and, eventually, a map of the QSOs.  Park Details Here's a look at the QTH. The vertical antenna is taped to a carbon fiber mast that is in turn supported in a tree with electrical tape. You can see the rig on the ground by the tree. Happenings When a touchdown was scored in the SuperBowl at one point, there was a seven minute delay till the  next QSO. QSO Map: By moving the animation slider all the way to the left, you can see all the QSOs at once. Clicking on play will play the QSOs in order as grey line moves along as...

AIs, Coding, and the Age of Ideas ~ Also the Week in Review

 I found ChatGPT o3-mini the day after it relased last weekend. I then spent most of the weekend cranking out apps that I've wanted for months and could now have up and running in about an hour and then fairly polished about an hour after that. It was outstanding! I'd used ChatGPT to help with the CW historgram over the last few weeks. Coding wennt quickly, but occasionally things got dropped on the floor. o3-mini has exceeded all my expectations by just cranking out code that works. Oh! Before I forget, the point of this post was to point out, (pun intended), an article Simon Willison mentioned that talks about the age of having ideas and making them real quickly. The article by Geoffrey Huntley talks about this kind of rapid prototyping and the cultural shifts among developers that are happening around it. Here's a sampling of what I've done with o3-mini: I've wanted a web control panel for our, (we is KO6BTY and I, KD0FNR), ham radio, Project TouCans ever since...

Project TouCans Web Control Panel ala Chat-GPT o3-mini

 Changing TouCans so that the Pico-W that controls the rig could be accessed by my smartphone hot spot did more than just get rid of the noise coming back from the rig. It also allowed me to start thinking about a Project TouCans web based control panel, a project I'd given up on last year when I decided that the Pico-W had to serve as the host of the network for TouCans rahter than just another device hooked onto a larger network. With TouCans hanging on the same netowrk as the laptop I usually use to control it,  the laptop was able to also access the internet at large through the phone's hot spot. I quickly thought through what this might enable. I then, asked o3-mini to write  up a web page for me, and before very long at all, I had: Messages typed into the 'Custom Message' block are sent out over the keyer when the 'Send' button is clicked. The page contains panels that show both the Utah SDR that's most like to pick up TouCans, and the Reverse Beacon ...

BBC Sound Programs with Morse in Mind

 Did you know there's a Morse keying world championship? Neither did I, but Martin, a ham radio op from the UK does. He's compiled a list of episodes from the BBC Sounds podcast that leans into the radio-esque, but contains other interesting topics including a family who, well.. here's a quote from Martin's blog: In 1966, Roy Bates occupied a disused military platform in the North Sea, and moved his family aboard.The next year he declared it to be the sovereign Principality of Sealand. Martin also did a cool thing and started a list of internet links referred to in the GQRP Sprat journal . It looks like it would be a lot of work, but it's a welcome relief from typing in addresses from the printed pages of the journal. I love that the journal is printed by the way, don't get me wrong.

Project TouCans Lab Book: Changing the Pico-W to a Client Eliminated all Pico-W Noise from TouCans!

 The radio is so quiet! I mentioned that I changed the configuration of Project TouCans so that my smart phone's hot spot serves as the centrial connection for TouCans and the computer(s) we use to control it.  Yesterday, at the Pony Express National Historic Trail, I only made a single POTA QSO on 20 meters with TouCans, but it was an unbelievably noise-free one: You can hear background noise in the real world—planes, waves, boats, people wandering by—from the camera. You can also hear some pretty gentle AM broadcast interference, but that's it! To give you an idea of how much things improved, listen to this QSO from before the change. The helicopter noise you hear in the video QSL below is from the Pico-W. The screehing noise also appears to have been from the Pico-W.
