Got bored.🙄
Decided to pull airplanes out of the sky with my @M5Stack 🛫📡
Turned it into a pocket radar that sniffs unencrypted ADS-B broadcasts from flights in real time.
Altitude, speed, heading all on one tiny screen! 🛠️

デイトンで発表されたICOMのX-026
本体部の大きさはic-706程度
ここから推測するとHF～430 ALL MODEは確定で、ATUや1.2G帯が入れば頑張った感が出て来る

Took the TETRA signal analysis further:
Extracted the TDMA frame structure from the power envelope using a simple FFT-of-FFT approach. TETRA frame period confirmed at 55 ms (spec: 56.667 ms).
Two standalone scripts, pipe them together: extract_power_envelope.py | find_periodicity.py

I been working on a project. This is focused on vhf propagation at your antenna. I made the decision to provide it free, with a donate button in the about section.
If that interest you see more shoot it here github.com/RF-YVY/APRS-PropV…

Just made a U.FL connector version for the RTL-SDR/GPS/LoRa/RTC hat for the Raspberry Pi. So it can be easily installed on other devices, like the Waveshare PocketTerm35, and turned into a portable SDR station. @geerlingguy

Just received the first SMT PCB of the Raspberry Pi RTL-SDR/LoRa/GPS/RTC Hat from JLCPCB, and everything works like a charm. I even implemented the GPS PPS indicator as @geerlingguy suggested.
I can think of some fun use cases with it, like using an RTL-SDR to listen in on emergency broadcasts, converting the audio to text, and broadcasting it over LoRa to a public Meshtastic or Meshcore channel. If you have better ideas, drop a comment and let me know!
Maybe a perfect hat for the #DragonOs when using with Raspberry Pi. @DustinFinn @cemaxecuter
