We're in a Golden Age for Amateur Radio

> I also learned how effective logging can be, and have applied that in just about every area of my life.

This statement really piqued my curiosity. Would you mind expanding on it?

The license is only needed if you want to transmit. If you are not interested in talking to random people, there is a lot of fun to be had from just picking up signals and listening. There are hobbyists who enjoy picking up distant AM radio stations, listening to all kinds of voice or machine traffic on shortwave, tracking aircraft by their beacon signals, or just listening to local police on scanners.

As a listener myself ("SWLer") my next project is to make a radio to pick up telemetry from small cubesats.

Sure, as a radio operator, even just a listener-operator, you quickly find that A) you are expected to keep a log, and in many situations _must_ keep a log (contests are a good example), and B) a log easily runs circles around your memory. As it turns out, logs also provide a helpful context for bridging the gap between the subjective and objective lenses, both of which are helpful and needed for solving problems, reaching goals, etc. no matter the activity.

In many areas of life, I knew I was really far too subjective due to my research into my personal psychology (I'm a professional coach) and wondered about different ways I could be _more_ objective without actually becoming an external sensing-measuring device. :-) Reading about logging tools like SINPO[0] helped me intuitively identify new ways of logging & spreadsheeting my way through different activities and situations.

As an example, when I get sick, I now engage this logging skill rather than just feeling my way through the illness, and I get to see some really cool emergent properties of this new personal system. I usually monitor my vitals in addition to writing down some subjective 1-10 ratings of how I feel in terms of general wellbeing, nausea, depression, and anxiety as the day passes. I have an autoimmune condition and while I can't just take a pill and cure that, my logs have shown me the peaks and troughs of amplitude within every passing hour of severe illness, when those illnesses come. I discovered that as I watch this data I can be more nuanced about the way I treat my sick time, and ended up actually getting productive work done that I _wanted to get done_ while "sick", by recognizing the high points and patterns in rest and energy buildup. "Riding the waves" with more precision, so to speak. There is also the analytical side of this, where I'll occasionally look back through my logs and see icons like a circled "!!!" which means "wow you tried something new here and it worked amazingly well, please add this to your toolkit for this activity from now on."

Because you're effectively engaging more of your "sensor suite," you kind of feel more like the space ship that can navigate the asteroid field vs. the one that really gets banged up. When you fold in the analysis step, it's like you're now better able to approach even more treacherous asteroid fields--your machinery is getting upgrades over time.

Incidentally, when I meet up with a doctor, I can be much more accurate about what happened and when.

I do the same logging thing at work, and now keep logs as part of just about every project. In some cases this is a literal mini-blog on a web page, and in other cases it's a text file tucked somewhere 15 folders deep, and in still other cases it's a small mark in the margin of a paper journal page.

I also discovered that this helps with other hobbies. I run RPGs for my kids and develop my own table-top RPGs, and keeping a log is a huge tip for a really effective campaign. Later on the log can become a published, written narrative (e.g. Record of Lodoss War), or mined for new ideas.

I used to struggle to keep a personal journal, but I've since found that I can more easily approach the practice by starting from the "Stardate" mindset and being a tad more robotic regarding current circumstances than I can by trying to keep the personal history that used to come to mind when I'd consider journaling.

Another thing I've learned is that we are extremely brittle about this practice, as a society. Our thinking about keeping logs tends to be black & white (a common sign of lack of education on the matter) and we hesitate or think in terms like "OCD" when people around us really leverage this practice[1]. IMO this is really unfortunate.

Anyway I hope this expands on it a bit!

Just to chime in, I saw an old-timer keep a daily work log in a text file, and that appealed to me so I started it too. This was in 1998, and to this day I still keep writing new entries to that same text file pretty much every business day. Old test account credentials, notes on what got done, ticket numbers, ideas, unfinished todos, the works. It also helps with time sheets at the end of the month :-)

Low solar activity means that there is less EUV (extreme ultraviolet) radiation hitting the ionosphere. This leads to weaker plasma formation, as well as shifting geometries of the plasma layer. In general the lower and weaker plasma tends to restrict the range of HF transmissions attempting long distance communications via refraction through ionospheric plasma.
