Apparently a #SDR repeater just got authorized for usage in our area. The repeater uses a Lime Microsystems radio and GNU Radio for some of the DSP.

Got this block diagram from the authorization documentation

I wonder if it makes sense to approach job search through hobbies and side activities rather than just by past employment history.

In my free time, I do #microbiology. I have a #biolab in the cellar with petri dishes and microscopes and all. I ferment #olives which grow in my tree and make pickles out of them, I make two kinds of #sourdough bread from a culture I extracted from quince fruit peels from my own tree, one wheat and one #rye.

I do #mycology. I have some 2,000 photos of wild #mushrooms in my Facebook photo albums.

I do a lot of software-defined radio, I have more #antennas than I care to count, and also more #SDR modules than I care to count. I stream radio data directly to my own #ElasticSearch which I can visualize in different ways in Kibana.

I do home automation, and the house has countless sensors and cameras. I use #HomeAssistant for this, with lots of modules I have implemented myself, for example for scraping data from my Huawei solar panels and graphing their historical data.

I have a home #Kubernetes cluster with many nodes and several public-facing services with some 99.9% uptime like a local Mastodon instance and also a #Matrix instance, in addition to lots of local services.

I am a data archivist and I have lots of stuff backed up locally if the internet goes down like it did during the notorious #apagon in Spain.

I play strategy games in Playstation, some of my current favorite games are #Stellaris and #Tropico6. I just like resource optimization over time.

I grow vegetables and some fruit trees. Trying to get really hot chilis growing here as they aren't readily available in stores. I have eaten the One Chip Challenge without even wincing a bit. I am a #ChiliHead.

I administrate all sorts of online communities and web pages. I read a lot of books and whenever I get into a new domain, I tend to read several definitive reference books of the topic from cover to cover. For example I now know more about #cancer biology than I ever thought I would.

I used to take a lot of #Coursera courses, also in non-technical topics such as #virology, #BrainPhysiology, #AnimalBehavior and such.

We have 3 cats, 2 siamese and 1 rescued as a kitten from the neighboring empty plot where he was born.

Ask me anything about these things!

If you need someone like this in your team to build great things, working remotely from Spain, let's chat!

Mord in Monkstead – Krimi Hörspiel von R. D. Wingfield

https://www.youtube.com/watch?v=–K-yX_a6V8&t=86s

Zehn Jahre liegt der berühmt-berüchtigte Doppelmord von Monkstead schon zurück – und niemals hat man auch nur den geringsten Hinweis auf den Mörder finden können. Weder haben die Ermittlungen ein Motiv erkennen lassen noch den ungefähren Ablauf der bestialischen Tat, der ein Hochzeitspärchen zum Opfer gefallen war. Aber Inspektor Ridley will nicht lockerlassen. Stets zum Jahrestag der Morde reist er an den Tatort, um jeweils von neuem den Zeugen auf den Zahn zu fühlen. Die sehen ihn, nach den langen Jahren, natürlich nicht gern in Monkstead und finden ihn penetrant und unausstehlich. – Süddeutscher Rundfunk 1973

@sacha @screwlisp @dougmerritt @zagebo @vavakado I'm trying to figure out how to maintain a wireless terminal connection with my home computer up to 10km away (further's edge of town)

Via #Reticulum over #LoRa (#rnode) or another #MeshNetwork. #PacketRadio, #MANET, #BATMAN, #SDR, etc

I'm not sure where this is going if anywhere ¯\_(ツ)_/¯

Fixed one of my SDR (software defined radio banks. This is a giant heat sink, salvaged probably from some kind of scientific equipment or a stereo. Drilled some holes, used both double sided thermal tape and zip ties to attach. (Previously tried just the tape, which detaches when it gets hot. 🤔). Previously used for satellite monitoring, currently being used for ACARS. Could probsbly do both. #sdr #rtlsdr #hamradio #aviation

I now understand more clearly why people don't compile things on Android in Termux. Ugh.

Also why are there not more SDR apps for Android? Is the above statement the reason?

Dear lazy web of the blind. Any pointers on how to start with Software defined radio? Accessible software, equipment etc. #blind #a11y #sdr #radio

Самописный SDR для спутника RS44

Изучая вопрос наличия подходящего софта для проведения связей через популярный у радиолюбителей спутник RS44 (ДОСААФ-85), с удивлением обнаружил, что подходящей мне программы просто нет. SDR всяких написано уже не мало, но вот так чтоб работал дуплекс, при этом были разные диапазоны приёма и передачи, коррекция допплера, да ещё и разные виды модуляции на приём и передачу – такого не сумел найти. По этой причине пришлось написать свой минималистичный SDR, специально ориентированный на решение только одной задачи – проведения связей через RS44. По традиции, решил написать программу на Rust. За деталями работы программы и ссылкой на гитхаб прошу под кат.

QRadioLink version 0.9.2 has been released today.

Changelog:
* Fixed low output power in SSB mode
* Improved Controlled Envelope SSB transmitter with correct parametrization
* Added audio compressor for SSB and AM modes with more aggressive settings
* Improved AM transceiver
* Some fixes for DMR promiscuous mode receive
* Fixed includes on some distributions

I must thank Ron W6RZ for his guidance on setting up the Controlled Envelope SSB parameters properly.

A few pics with the signals right at the output of my ADALM-Pluto in the 2390 MHz band, before amplification. In order or appearance: 4FSK, DQPSK, GMSK. I don't normally use the GMSK modem due to it's slightly lower performance, it's just there to spite my D-Star-using friends. Audio payloads are Codec2 and Opus.

The amplification chain has two stages: first to ~16 dBm, second one to ~36 dBm.

Completed a few tests on the 2.4 GHz RF Equipment (RFE) components for the single-band Pluto transceivers. TLDR: All looks good and ready to continue evaluating controller software. Details at the qsl.net blog. #HamRadio #SDR

My #Introduction.

I talk about life in #CambridgeMA and #Boston, #engineering, #science, #radios (#SDR, #HAM, #LoRa, #MeshCore), #pinball, #film, retro computers/video games, and more.

I collect #art, #LaserDiscs, study #horology, visit museums (The Met, MFA, Harvard Art #Museum) and support my local #library.

I read #poetry and books on #architecture, #design, and #urbanism.

I walk or take public #transit everywhere.

I practice #permacomputing and self-hosting, running #BSD where I can.

Thách thức lớn nhất khi áp dụng AI SDR không phải ở công nghệ mà là tâm lý con người khó chấp nhận việc AI làm tốt hơn. AI tạo danh sách dựa trên chức năng công việc thực tế, gửi tin nhắn ngắn gọn, trúng trọng tâm. Cách làm tiên tiến này thường bị từ chối do không khớp kỳ vọng truyền thống. Đây là vấn đề về giáo dục, không phải sản phẩm.
