You can see a sharp decline in activity about mid-screen.
About 1m 15s remaining:
45s after 1200Z:
You can listen to your heart's content here: http://websdr2.sdrutah.org:8902/index1a.html?tune=14290usb (where this image is from).
If you want to get in on the action, consider pursuing your Amateur Radio Operator's License. If you're in the US, the Amateur Radio Relay League is a sufficient place to start, and you can use hamstudy.org to prepare for your test.
In the 14Mhz range you'll see a diurnal oscillation of who you can hear because during the day this particular band tends to only get out to about 1500 miles, at night we can reach over 10,000 miles. I've had plenty of contacts with Japan, and on digital modes I've gotten out to 11,000 miles. I've made contacts in Indonesia from New Mexico. On digital mode (which does not use voice) I hit the Reunion Islands on the east side of Africa with only 100W and a vertical omnidirectional antenna.
Number stations are wild. There's even more to signals intelligence, too. There are Over the horizion radars (OTHR) and bouys, wave radars, and wildly encrypted digital bursts–all of which you can hear.
This is a wonderful question! This is a spectral waterfall display of audio frequencies. The dense area on the left are the CW (Morse code) portions of the spectrum where there are quite a lot of people communicating in Morse code. The bright bands just to its right is the FT8 data mode (which also uses audio frequencies) to send and receive very short messages. The broad area on the right are people communicating via voice transmissions on Single Sideband.
Granted, this is the IARU Championship. But that's a lot of people on the radio.
Ahh, so that massive outage in Feb was a DDoS misdirect.
Just a quick WAG: at one point it was the topmost sail, and then someone was like “what if we put another sail on top of that one so we can go seven speed?”
The next sail on top became the Gallant, and so forth, apparently topping out the tech with a Moonraker.
no no, it’s the Magnum effect.
And they even have DNS profiles for most devices. I’ve been running some form of AdGuard for nearly a decade. On the rare occasion I do see an ad, it’s quite surprising.
This holds true for a great deal of contemporary thoughts for any given time.
Everything is arbitrary and we all make it up as we go along.
I always have a double take to be sure.
Filipino, for the curious.
Our timeline is, unfortunately, aligning with the movie The Purge.
20m at 1500Z.
Side note: for the last three days I’ve enjoyed nearly bottomless noise floors; been making SSB QSOs to Japan, Indonesia, and even Rarotonga. Then–today of all days–the AirBnB beside my house has turned on their aircon and it’s completely wiping out all but the strongest signals. My waterfall looks like college ruled notebook paper:
1830Z Update:
1900Z. This is wild.
Man, what an amazing day which will be long–if not impossible–to forget.
In the late 90s, I observed my first partial eclipse from South Florida. Then and there I decided I needed to see a total solar eclipse. Nearly 30 years later, I made good on that little personal promise. The moment I realized I would be in position to get along the path of totality, I made plans with my spouse to do so. We saved the date and planed the logistics.
I, of course, ensured my radio was packed and fully functional; charged the battery the night before. We left Del Rio, the closest place we could find reasonable accommodations, at 0400L. By 0700L we had hoisted and strung the OCF dipole and we were ready to go in DL98rv, just under the central path of the eclipse on the side of Hwy 131 in Texas just beyond the US-Mexican border.
The Tech section of 10m was silent that early, but I kept calling CQ until I started getting QSOs, pretty much went ten in a row in nearly the same number of minutes once the band came alive.
I had wanted to participate in the research project contest, but the instructions and bonuses were a little overwhelming, but I did manage to make one QSO during totality. On the one hand, I was expecting propagation attenuation, but the QSO I made was over 1,500 miles away.
I've read over and over about experiencing totality. Photos will never do it justice. Words doubly so. If you've ever been on the fence about traveling to see totality–just do it.
Lessons learned or confirmed:
I am eager for your questions and feedback!
Let’s QSO!
