My previous intro post was a few years old, so behold, new intro post:

Mike. Live in the Seattle area having grown up in the UK as a full blown British. Have a wife (incredible), child (boy), and three dogs (golden retriver/cream retriver/fuck knows).

I work in information security, something I have done for about 20 years. By day I run corporate security, enterprise IT and various other bits and pieces for an EV charging startup. I am big into EV's and currently drive one that is not a Tesla. I want an electric motorbike, so if anyone has a spare one please send it.

I also have a company of my own, Secure Being (https://securebeing.com), which does pen testing and digital forensic work - it's my way of staying super hands on while still doing the management bits on the career path.

I have written books about information security things. Five of them. Two are non-fiction textbooks, and three are fiction based on real world #infosec things. Check out https://infosecdiaries.com and your local bookstore to find them, just search for my name. I have been trying to write more stuff, but always seem to find myself distracted by other things, such as work. linktr.ee/secureowl has some mini stories I've written.

I love radio and everything RF. I have lots of antennas and various scanners and radios on my desk. I love intercepting and decoding things, like digital radio protocols.

I am a big aviation nerd. I always wanted to be a commercial pilot. I gained my private pilots license in the UK at 17, all self funded by my employment at the local Safeway/Morrisons store. I did the sim test and commercial assessments, but for some reason, at 18, I was unable to find the £100k needed to complete the commercial training, so I did computers. But do not worry, because those computers and love of aviation and radio/RF combined, and I run a project called ACARS Drama. https://acarsdrama.com has all the details.

I play guitar and am a big guitar/audio nerd as well. I record music under the moniker Operation: Anxiety, https://operationanxiety.com - the music is on all the normal places.

Finally, I am a massive fan of motorsport. I believe I have watched every F1 race for the last 30 years, maybe 25. I also follow F2, FE, Indycar and MotoGP closely. I average around 18 hours of Le Mans 24 hour racing watching per year.

So there you have it. If you are looking for a thought leader on the topics mentioned above, you've come to the wrong place - because this is where I shitpost, and shitposting is cheap therapy.

Hello mastodon.radio!

I just got my license earlier this year, inspired by the role hams played in the Hurricane Helene mutual aid disaster relief and by @mediaarchaeologylab's writings about #othernetworks and radio.

Right now I'm studying for my general license, reading about #sdr, and learning what there is to learn.

I hate having to scour datasheets to find out what the difference is between two parts of almost identical number. Apparently the CC1201 is the sawed-off low-cost version of the CC1200: "The CC1201 offers the same performance as the CC1200 for channel filter bandwidths of 50 kHz or more,
and therefore presents a lower cost option for applications that do not require narrowband support."

If you are interested in PlutoSDR or any of its clones like the LibreSDR, there's an open source project by @f5oeo working to enhance the firmware for these Zynq/AD9363 based #SDR devices.

While admitting that most of the Zero Retries amateur radio newsletter is way over my head — and I'm a General Class license holder — I was able to pull out of the most recent issue that THIS IS THE RADIO TO GET (and to beat):

Crowdsourcing #DSP creativity!

You could help @gnuradio 's block documentation wiki a lot if you could try out our instructions for how to add example flowgraphs to Block Doc pages!
https://wiki.gnuradio.org/index.php?title=How_to_Add_an_Example_Flowgraph_to_a_Block_Doc

The documentation team (and countless contributors) have created a host of 555 block documentation pages to date. Not every single one of these has an example flowgraph that really illustrates the useful things you could do with that block.
Could you help?

Getting into gnu radio, wanting to put my HackRF to use. Want to actually get a decent understanding of RF theory.

Messing around with GPS signals, going to try to work out autocorrelation and things.

the new rust library plays FM radio stations. now it's time for bed.

Dear #AskFedi,

has the whole Internet™ decided that wireless mouse with a lost dongle aren't worth hacking? Does nobody in the #SDR community tried? It would be hard for me to believe and quicker I would say that there is a mass of failed experiments and unwritten blog posts.

P. S. I am wondering very hard about this as I'm tempted try to save an Elecom Huge from the e-dump (whilst knowing barely anything about SDR).
