Cell reception is always bad at the volleyball tournaments and the coach couldn’t stream live videos to family that couldn’t make it.
Built this thing - wireless AP to cellular built amplifiers inside the battery casing with Omni directional antennas and our own private WiFi.
We cookin and streaming now 😂

Dads… What do you want for Christmas this year and why is it a battleship?
If your answer is not a battleship, please tell us… when did you stop being a man?

Kicking off the day with Bitchat running on DragonOS. Secure mesh comms, anyone? 🚀

Upgraded the remote, solar-powered SDR outpost to DragonOS Noble. The LibreSDR will also rejoin the lineup alongside the RTL-SDR and Airspy HF. Looking forward to some real-world testing (and probably some interesting YouTube content) with this crew out in the wild!

Another GPS mod for WarDragon Pro I might make standard once the wider bottom plates are in. Adds an optional 5th antenna spot— but for my test I just repurposed the SDR’s TX port (for those with a kit and not wanting to drill). Still waiting on the "ultimate GPS" for comparison.

Might be back in the game with LTESniffer. I’ll try going after Starlink DTC (looks like it’s FDD, not TDD). Just me, my Yagi, and a whole lot of Doppler shift. Guess I’ll see what happens.

Working on updates in DragonSync’s dev branch to improve WarDragon Pro’s ATAK/TAK support. It may be quiet now, but trust me—big things are coming. #WarDragonPro #DragonSync #ATAK

Out with the old @rtlsdrblog Discovery Dish + @airspy_com HF+ remote box, nearly in with the new one. @Victron_Energy. Not sure what all the components plus battery inside will do in the EMS, guess I’ll find out.

WarDragon Pro Kit. Solid build, and a quick snap of the back reminds me not to forget the vent covers. Ready for intense #DroneDetection, #SDR, #SpectrumAnalyzer, and #EW action! 👍

Here’s the steps necessary to allow the WarDragon Pro and a TAK server to communicate, both via UDP and TCP w/ certificates. DJI DroneID tracked w/ home, pilot, and drone location shown.

Uploading a new Pi image asap, because having WiFi out of the box is pretty important.. thanks @gm8arv for feedback! Also made gr-gsm/imsi catcher work again, but had to remove gr-Iqbal from osmosdr.

A massive thanks to @LukeSwitzer_ for the incredible work on this application. I’ve wanted an app like this for a long time, but this one has exceeded every expectation. The fact that it’s open source and built entirely through voluntary effort makes it even more impressive!

Some of the steps for getting map data and doing propagation analysis may come in handy if I can get @TheMeshtastic’s RF planner frontend onto DragonOS. 🤞
