🎇 APRSdroid is back on the Google Play store 🎊
We got delisted for not fulfilling Google's new security requirements as of Android 15 (yeah, we are a bit late)
Additional changes:
- updated APRS symbols from @oh7lzb
- fixed Conversations view to show the *newest* and not the *oldest* message, tnx NA7Q
- build system now uses scalaAndroid by @scala_lang
Happy holidays!

This is the most important project in Amateur Radio today. It will bring us the capability of doing so many more things, and free us from the dumb radios with burned-in firmware that most of us use.
Who is helping? Who _isn't_ helping?
LoRa is awesome! This is the longest path my Lora-APRS gateway received a packet yet - 322 km on mere milliwatts of transmit power!
📡 TinyWSPR: Open-Source Silicon for Shortwave
We (JKU Linz and JMU Würzburg) built a fully WSPR-capable TX on open-source silicon (TT-Sky25b via @tinytapeout ). A digital subsystem generates symbols; an analog RF chain performs IQ modulation. FPGA tests already reached central Europe with just 10 mW on 40 m. Now we’re waiting for the chip from the fab for the first on-air tests 🤩.
APRS also Just Works™️

this demonstration was at very close range (~10m) using close to the fastest LoRA preset possible using this hardware: Bandwidth 500KHz, Spreading Factor 5, Coding Rate 5 (4 is less redundant, therefore faster)
