SARC Construction Project | Operation Meshtastic

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.

For the latest project details or to see the current build kit, you can check the SARC Activities page.

Further Exploration

  • Learn more about SARC’s ongoing projects on the official Construction Project page.
  • Explore how to integrate Meshtastic with CalTopo for SAR operations.
  • For those interested in building their own hardware, see this guide on building DIY Meshtastic nodes.

Are you looking for a specific parts list for a current SARC build, or do you need help setting up a Meshtastic node for your own project?

Upgrade to a General License with our Class

The Schaumburg Amateur Radio Club offers a free upgrade class for those already holding a technician-level license looking to upgrade to a general-level license beginning January 10, 2026. This class is intended for those already holding their technician-level license and who are looking to upgrade their privileges and bands that they can operate on to general class. This upgrade opens up a significant portion of the HF bands, including SSB (voice modes) for the operator.

This course is offered at no charge. The class is held from 09:30 a.m. to 11:30 p.m. on Saturdays from January 10 through March 14.

The class uses the American Radio Relay League General Class License Manual Fifth Edition (ISBN: 978-1625951717) as a study guide and students are encouraged to get their own copy.

SARC Bike Ride Sunday October 26

 

We have scheduled our next SARC group bike ride for Sunday, October 26th at 10:00a on the Illinois Prairie Path/Danada and Herrick Lake Trail.

The ride will start and end in the parking lot of the Kline Creek Farm at 1N600 County Farm Road, West Chicago. We will hop on the Timber Ridge Trail for about 1/2 Mile and connect with the Illinois Prairie Path southeast through Wheaton to the Danada and Herrick Trail east. We will turn around at the end of the Danada and Herrick Trail and follow the same route back. The route is about 23 to 24 miles total. The path is mainly crushed limestone with some concrete/paved areas.

This is a group ride and not a race, so anyone who wants to come out and participate can ride with us. We will adjust speed and distance accordingly.

Here is the map below with the trail and our starting point. We’ll meet at the parking lot at 10:00a.
