OMG I've been pulling my hair out trying to download Dragon OS from source forge, was super slow and given estimates of 3h+, failed multiple times. Had a brainwave to use wget, under 5 mins later and it's downloaded.... #DragonOS #wget

Как собрать LTE-модем на базе SDR

Приветствую всех! Пожалуй, самой закрытой технологией в пользовательском сегменте является сотовая связь. Очень немногие знают о том, как на самом деле работают телефоны и модемы, отчего им часто приписывают всякие мифические свойства. Как насчёт попробовать запустить полностью открытую реализацию модема стандарта 4G? Именно этим я и предлагаю заняться. Итак, в сегодняшней статье поговорим о том, как взаимодействовать с мобильной сетью при помощи SDR. Попутно узнаем, какой софт для этого существует, и соберём самый дорогой 4G-модем в истории. Традиционно будет много интересного.

Currently stress testing (ie just using the thing with a good antenna) a nice little Iridium rig sent by @cemaxecuter
We are trying to find the sweet spot between price and performance for a 'it just works' hardware kit.
Running #DragonOS of course.
It goes great till those sustained runs of 1000+ bursts of #iridium goodness fall out of the sky onto the antenna.

In times of turmoil, upset, and uncertain futures, at least we have #WWV. For now, at least.
And no, I haven't logged into my Mastodon instance on this system yet, so deal with the potato screenshots. #DragonOS #SDRpp #AirSpy #HFplus #swl #hamradio

Nice, time to find out where this broadband noise source is. #ham #hamradio #interference #mediumwave #40meters #DragonOS #SDRpp

Running #DragonOS as a VM... let's see how badly this burns!

@parvXm Hi parv, entec, thanks. .. I'll trying them out and see which one I like. This was the only qwerty laptop of a bunch (I'm in azerty-country here), so it probably was used as a dev-machine. I might turn this into a dual-boot machine (#freebsd #dragonos) for my other hobby (#hamradio) but need to find out first how to do that. Thx for the help. :thumbsup: Appriciated!

More Software-Defined Radio Projects Using DragonOS

DragonOS, a Debian-based Linux distribution specifically packaged for software-defined radio functionality, roared onto the wavelengths during the beginnings of the various pandemic lockdowns last year. Since then [Aaron], the creator of the OS, has been busy adding features to the distribution as well as creating plenty of videos which show off its capabilities and also function as how-tos for people who might want to learn about software-defined radio. The latest is a video about using this software to detect radio signals in certain specified spectrums.

This build uses two RTL-SDR devices paired with the DragonOS software suite to automatically detect active frequencies within a specified frequency range and that aslo exceed a threshold measured above the average noise floor. The video includes the setup of the software and its use in detecting these signals, but also includes setup of influxdb and Grafana which provide logging capabilities as well. Using this setup, multiple receivers either local or over the internet can then be configured to dump all the identified frequencies, powers, and time stamps into DragonOS.

[Aaron] has also been helping developers to build the SDR4space.lite application which includes GPS support, so he hopes that in a future video a user will be able to easily associate location to identified frequencies. Projects like these also serve as a reminder that getting into software-defined radio is as easy as buying a $10 USB radio receiver and configuring some free software to do anything that you can imagine like tracking ships and airplanes in real time.
