I've posed my slides and linked to the video recording from my talk "Paging All Radio Curious Hackers!" at @DistrictCon Year 1 just now at https://k3xec.com/paging-all-radio-curious-hackers/

All in all, the session was great – It was truly humbling to see so many folks interested in hearing me talk about radios. I had a bit of an own-goal in picking a 20 minute form-factor, so the talk is paced wrong (it feels like it went way too fast). Hopefully being able to see the slides and pause the video is helpful.

#Hamradio Manifesto : from usage to creativity

A short writing to define a strategic transition: moving from passive use to the design of resilient and innovative communication systems:

* an open & modular RF stack
* Mesh Networks and Technological Resilience
* RF Hacking and STEM Education

More to think about here:

Manifeste #Radioamateur : de l'utilité à la créativité

Une bafouille pour définir une transition stratégique : passer de l’usage passif à la conception de systèmes de communication résilients et innovants :

* une pile RF ouverte & modulaire
* Réseaux Mesh et Résilience Technologique
* Hacking RF et Éducation #STEM

I couldn't resist! Say hello to my little RF hacking toy. Took out this Christmas gift for a test spin today, and it worked like a charm.

🤔 BẠN ĐANG LOAY HOAY KHÔNG BIẾT CHỌN KIỂU MẶT BÍCH NÀO?

FF, RF, RTJ hay M&F, T&G… mỗi kiểu bề mặt kết nối mặt bích lại phù hợp với một điều kiện áp suất và môi trường khác nhau. Chọn sai có thể dẫn đến rò rỉ, mất an toàn cho hệ thống đường ống.

Letzten Donnerstag in China bestellt. Heute angekommen. Ein Frequenzgenerator von 23.5 MHz bis 6 GHz. Einigermaßen genau. Allerdings dank Rechtecksignal Oberwellen bis sonstwo. Ergo nicht an eine Antenne anschließen. Aber was will man für 47€ auch besseres erwarten. Für meine Zwecke reicht es. #elektronik #rf #generator #hamradio

Had such a blast at @DistrictCon year 1!

I was so thrilled to be able to give my first ever #RF related talk about how to set off restaurant pagers (including one on stage!). Massive thank you to the organizing team!

I'm looking for a Wideband 1:1.5 transformer preferably with SMA connectors something like this:

https://www.minicircuits.com/WebStore/dashboard.html?model=ADT1.5-17%2B

But mounted on a board. Needs to go up to 1500MHz.

If you know of anything I'd love to hear.

“HIGHLIGHTS:
• ViT-based forest mask, multispectral ensemble LandTrendr and terrain shadow mask.
• District-level RF/XGBoost model training with expert-weighted validation.
• Outperformed GFC and REDD + AI benchmarks in accuracy and F1 performance.
• RF excelled in High Mountains/Himalayas; XGBoost in the lower Mountain regions.
• NBR contributed the most; snow-impacted forest loss uncertainty was observed..."
