Project TouCans/GloTEC F2 Maps

This has been fun! KO6BTY and I have been working on QSO maps on 20 meters vs. the F2 layer for the last few years. We finally have a map of the F2 layer, one half hour behind real time with global data provided by the NOAA's GloTEC product . Check it out .

Using o3-mini to Set up a Log Book Transfer for use with QRZ.com

 New ham cleans up log book on QRZ with the help of o3-mini. A few days back, after the completion of SKCC month, a ham sent out a message asking others to please post their QSOs ot LoTW and/or QRZ.com for award verification. For me, a light bulb burst on. It does matter that I log my QSOs publicly. It had frankly, never occurred to me before, but it made sense. o3-mini and I got to work. I already have a log book built on Datasette for my QSOs. I just needed to get the QSOs from there and ship them off to QRZ.com . I needed it to be automatic though, since there were more than 1,000 QSOs to transfer. I asked o3-mini to write a Python script to do this for me. I gave it the database schema for my QSO database. I also fed it the l ogging API instructions for QRZ.com.  I had something that worked well enough after about 40 minutes. After three hours, that included a 40 minute coffe break, I had a script that automatically calculated my tx grid square, (it changes a lot becuase...

Halikey Works on My Chromebook Again!

 I got my Halikey to work on my ChromeBook again! Regular readers might remember that I chose poorly when my ChromeBook asked what I wanted to do with the Halikey, assign it to Linux or Android? The correct answer was not to choose . Both choices are wrong. After a bit, the dialog box will simply disappear if you don't answer. Then, everything works fine. The settings stored my choice in a place I couldn't find... until today... and so, no more ChromeBook HaliKey for me. Here's what made everything better. I went to the ChromeBook's settings and wound up at the Manage USB devices tab. It wasn't easy to figure out. I have yet to find a path to this screen. Here's what you can do. Select settings in your Chromebook. Click into the 'System preferences' tab. Search for usb, but do not hit enter. Notice the , 'Linux development environment' selection. Choose it from the drop down. Then, click on 'Mange USB devices in that screen. You'll land a...

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...
