Software Defined Radio
SDR lets operators visualize signals, monitor spectrum, and experiment with digital signal processing.
Raspberry Pi
Small computers can power hotspots, logging tools, digital stations, weather displays, and radio services.
Arduino / ESP32
Microcontrollers support sensors, telemetry, displays, station automation, and custom radio projects.
Mesh Networking
Mesh systems can create resilient local data networks for events, experimentation, and preparedness.
Meshtastic / MeshCore
Low-power LoRa systems are useful for messaging, tracking, and technical learning.
Linux & Networking
Many modern radio tools run on Linux and use networking, servers, APIs, and automation.
