Radio Software

I use Zello to link audio received on multiple SDR radios at home to my phone when I'm out and about.

Channels on the SDRs are fed via virtual audio cables to the Voicemeeter audio mixer, which has a remote macro addon which I use to prioritise some channels over others by having one channel mute others if they're active together. The mixer output is fed to Zello and Zello uses "vox" mode to key the "transmitter".

On 25th June Zello pulled support for the older free Zello PC app I used, and the service stopped working. Thank fully there's a workaround, as Zello are continuing free use for Friends and Family using the mobile app.

By running Zello mobile on the Bluestacks Android emulator in Windows, I can continue to use the facility. Happy days!

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.

Made a few simple maximum volume level measurements for the family’s HT collection to see which are loudest and in what configuration (radio alone or radio + speaker microphone). Have a better understanding of what radios to use for different operating conditions after these tests. #HamRadio #AudioTest #HearingProtection #SDR

“Off We Go To War: Starmer’s Strategic Defence Review”

by Binoy Kampmark in Savage Minds on Substack

“Unpopular governments always retreat to grounds of lazy convenience. Instead of engaging in exercises of courage, they take refuge in obvious distractions. And there is no more obvious distraction than preparing for war against a phantom enemy”

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.

“THE UK BADLY NEEDS AN ALTERNATIVE DEFENCE REVIEW: HERE IT IS”

by Kate Hudson in Declassified UK @Declassified_UK @UKLabour

“Labour is persisting with a ‘nukes plus NATO’ defence policy that is likely to lead to further wars. A new independent report counters this disastrous narrative”

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):

https://www.hfsignals.com/index.php/zbitx/

So I added another SDR to my #PiAware device for 978kHz, because a few flying machines flew over but I didn't get any info from them, so I assumed they were using the older wavelength, and I've sadly not seen anything yet.

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.

Your disaster kit needs a weather radio—it’s a lifeline for #NOAA and #FCC alerts in emergencies. But imagine getting not just audio updates but also images, charts, & reports off the grid. The future of weather radios: https://spectrum.ieee.org/software-defined-radio #SDR
