What is a Repeater Crawl?
A Repeater Crawl is a coverage testing event where amateur radio operators check in to multiple repeaters from their location. This helps us understand:
- Which repeaters provide coverage to different areas of Macomb County
- Signal quality from various locations to each repeater
- Potential coverage gaps that may need to be addressed
- Backup communication options for emergency operations
During a crawl, each station checks in to each repeater in sequence and reports their signal quality using the RS (Readability-Signal) system. The data collected helps improve our emergency communication capabilities.
