Roughly 3,200 members of the International Association of Machinists and Aerospace Workers (IAM) went on strike at Boeing Defense's St. Louis-area facilities on August 4 after rejecting the company's four-year contract offer. They assemble Boeing's F-15 and F/A-18 fighters, the T-7 trainer jet, munitions, and wing sections for the company's commercial 777X jet.

Bryant was among the union leaders who joined workers in picketing, along with Bell, whose congressional district includes many of the workers.

The offer rejected by St. Louis-area workers included a 20% general wage increase, a $5,000 ratification bonus and more vacation time and sick leave. At the time, Boeing said the bonus would not be offered again if that offer was rejected.

The other day I stumbled on a random post by Gary N8DMT which caused me to view the world in a different way. The post outlined combining a PlutoSDR and an application called SATSAGEN to measure the frequency characteristics of a coupler.

Aside from a detailed description, the post includes a couple of excellent photos showing the PlutoSDR connected to the coupler and the output piped back into the Pluto.

Before I continue, a PlutoSDR is a Software Defined Radio or SDR, officially it's called the ADALM Pluto Software Defined Radio Active Learning Module. It's essentially a full-duplex radio and computer in a box. It runs Linux and connects to the world via USB, and of course radio, unofficially between 70 MHz and 6 GHz. I've talked about this device before. When I say full-duplex, I mean that it can transmit and receive at the same time.

Gary's post triggered something unexpected in me. The notion that you could use two patch leads, one connected to the transmitter, the other connected to the receiver, joined together by a device that you might want to test.

It immediately reminded me of another device that was given to me, a NanoVNA, a device that's specifically designed to measure things like impedance, frequency response, generate Smith charts and all manner of other characteristics.

Not only that, it also reminded me of another device, a TinySA, specifically designed to analyse spectrum and to generate signals.

Both the NanoVNA and TinySA are lovely tools, but in looking at the post it suddenly occurred to me that their functionality, at least superficially, appears to mirror the PlutoSDR, in that you can create a signal and then measure that signal.

Turns out that I'm not the first to make this observation. For example, the YouTube channel "From Concept To Circuit" goes through the process of describing precisely the concepts behind both a spectrum analyser and a network analyser while showing the programming code in Python. The channel also provides that code in a GitHub repository, which includes several other very interesting examples, like a beamforming transmitter as well as a beamforming receiver, also covered on YouTube.

Another example is a tool I already mentioned, SATSAGEN, by Alberto IU1KVL, which implements a wideband spectrum analyser. Although it's Windows only, Alberto includes information on how to run it using Wine under Linux and MacOS. As a bonus, SATSAGEN in addition to the PlutoSDR, also supports RTL-SDR dongles, HackRF, USRP, RSP1, AirSpy, and many others.

If text is more your thing, "retrogram-plutosdr", shows a spectrogram in your terminal window. Check out the "r4d10n" GitHub repository belonging to Rakesh VU3RGP, who says that the "retrogram" project is "hacked from" the "RX ASCII Art DFT" example, which you can find on the Ettus Research GitHub repository.

One thing to consider is that the various GitHub repositories I've pointed at, will give you access to the moving parts of how all this works.

I will mention that my favourite tool in this space continues to be GNU Radio, but I understand that you might not want to roll your own tool from parts. That said, rolling your own is in my experience a great way to discover precisely what you don't know and to come away learning more, but then, that's just me.

Regardless of your chosen tool, I think the takeaway should be that when you try something new, even if it's only new to you, the idea of writing down what you discovered and sharing it, is a fantastic way to grow our community. Remember, just because something is old hat to you, doesn't mean that it is to the person you share it with.

Besides, based on the current global birth rate, there's at least a thousand babies born during the past four minutes, some of whom will become radio amateurs, so, share.

Said differently, if you come across a person who has never heard of the "Diet Coke and Mentos" thing, it's your job to immediately drag them to the nearest grocery store and introduce them. In case you're wondering, xkcd 1053.

Now, I'm going to update the firmware on my PlutoSDR and have a play, I already know about the Mentos, but if you don't, you're in for a treat.

What are you going to do next?

Graham Platner wants to oust Sen. Susan Collins — and disrupt national Dems’ plans to unite around Gov. Janet Mills.

By Holly Otterbein
08/19/2025

Platner is running on several progressive tenets — though he rejects the label “liberal” — and his announcement sets up the possibility of a clash between Democratic Party factions over generational change, Israel and other issues. In an interview with POLITICO, Platner said he would not support Chuck Schumer as Senate Majority Leader if Democrats managed to take back control in the 2026 midterm elections.

Platner embraced a number of progressive causes in his announcement video, calling for universal health care, saying “the enemy is the oligarchy,” and asking, “Why are we funding endless wars and bombing children?” He also zeroed in on high prices, a top concern of voters and one that helped fuel Mamdani’s rise in New York City.

I had met a woman working at my local mall's antique store. When I asked about fountain pens she said that while there weren't any in the store at the moment she had one gathering dust in her cabinet drawer and that she would bring it the next day. I had thought she was bring it to sell to me but she just gave it to me for free. It was a very pleasant surprise and the pen wound up being a TWSBI Vac700! There was also a store closing sale going on elsewhere and I have quite a few Christmas/Birthday presents. Today was a very lucky day.

Donald Trump has threatened to take his federal crackdown on crime and city cleanliness to New York and Chicago, as the defense secretary, Pete Hegseth, ordered that national guard troops patrolling the streets of Washington DC under federal control will now be armed.

The US president talked to reporters in the Oval Office and said: “When ready, we will start in Chicago … Chicago is a mess.” He added that then the administration “will help with New York”, amid the controversial and aggressive federal efforts to control leading Democratic-voting cities, each of which has a Black mayor.
