- The SDR Receiver: Recommend the RTL-SDR Blog V4 USB Dongle. Explain how it feeds live radio spectra straight into the GQRX waterfall container.
- The LoRa Mesh: Recommend Heltec V3 or T-Beam (915 MHz for US / 868 MHz for EU) nodes running Meshtastic. Detail how the app’s background listener pulls text traffic straight off the airwaves [CH].
- The Server Core: Recommend a low-power Mini PC or Raspberry Pi 5 tucked into a solar battery cabinet to run the headless background Docker containers (Navidrome, Kiwix, MeTube) 24/7, leaving the operator’s primary field laptop fast and unburdened.
