SARC Construction Project | Operation Meshtastic

While SARC is a traditional amateur radio club, members often explore emerging technologies like Meshtastic, an open-source, off-grid mesh networking system. In the context of SARC and similar clubs, Meshtastic projects often focus on

The SARC Construction Project refers to a recurring activity organized by the Schaumburg Amateur Radio Club (SARC) where members build various radio-related electronic kits and projects.

During the warmer months (spring and summer), this indoor workshop is typically replaced by SARC in the Park, where members move their activities outdoors to test portable radios, antennas, and “go-boxes”.

Meshtastic and SARC

While SARC is a traditional amateur radio club, members often explore emerging technologies like Meshtastic, an open-source, off-grid mesh networking system. In the context of SARC and similar clubs, Meshtastic projects often focus on:

  • Node Construction: Building DIY nodes using ESP32 boards and LoRa radios for long-range, low-power text and GPS communication.
  • Search and Rescue (SAR) Integration: Using Meshtastic for off-grid team tracking, often integrating with tools like CalTopo/SARTopo to see real-time team locations without cellular service.
  • Community Mesh Building: Deploying permanent “repeater” nodes on high ground or masts to expand the local communication footprint for the club and the surrounding community.
