Now you can configure and flash your #RS41 and #DFM17 #radiosonde with #hamradio firmware directly in a web browser (Chromium/Chrome-based, uses WebUSB).

The RS41ng configurator tool guides through the config/build/flash process and makes it fast and easy. This is just out, please give it a try:

(There may still be some rough edges, MCU unlocking is known to have issues)

🌘 Tiny4FSK: 輕巧的 Horus Binary 定位追蹤器，專為高空氣球設計
➤ 探索高空氣球追蹤的新紀元：Tiny4FSK 的技術剖析與實踐
✤ https://github.com/New-England-Weather-Balloon-Society/Tiny4FSK
Tiny4FSK 專案旨在開發一個極致輕巧、僅使用一顆 AA 電池即可運作數小時的高空氣球定位追蹤系統。此係統採用 Horus Binary v2 協定，並利用 4FSK 調變技術，能有效傳輸 GPS 定位數據。文中詳細介紹了硬體組件（包括 SAMD21G18A 微控制器、Si4063 傳輸模組、ATGM336H GPS 接收模組、BME280 環境感測器等）以及軟體架構，並提供了 PCB 的設置與天線系統的組裝指南。此外，還說明瞭 PCB 上的跳線配置與電源開關的應用，強調了該系統在業餘無線電頻段運作需要執照。
+ 這聽起來是一個非常有趣的專案！我對用如此小的裝置來追蹤高空氣球感到驚訝，尤其是它還能持續運作這麼久。

SP8ESA #hab #highaltitudeballoon started today: https://tracker.habhub.org/#%21mt=osm&mz=6&qm=1_day&f=SP8ESA-4FSK .
After lot of trouble (missing libraries, paths etc.) i have finally compiled horus-gui for linux 👌 . #4fsk

First try to receive #4fsk from #hab #highaltitudeballoon with #horus software. Horus is able to decode 4fsk packets from audio interface and send data to https://tracker.habhub.org. SQ6NEI #hab started today with very low ascent rate (almost 0 m/s at alt. ~5000m) so one can expect long flight. Unfortunatelly with low alt. the radio horizon is only ~250km radius. 1/2
