Visiting HAM Operators at the 24 Hours of Le Mans: Repeaters and Networks Available
As the world-renowned 24 Hours of Le Mans takes place, we warmly welcome all amateur radio operators (HAMs) visiting the Sarthe region. Whether you’re here to experience the race live or just passing through, several radio communication options are available to help you stay connected and exchange with fellow operators.
Available Repeaters Around Le Mans
-
- F5ZGG: This DMR (Digital Mobile Radio) repeater provides digital connectivity throughout the Le Mans area. Ideal for operators using digital equipment, it ensures reliable coverage across the region.
- F1ZMP: Located at the Le Mans Radio Club, this analog VHF/FM repeater is accessible to all operators with standard analog equipment. It serves as a key local contact point.
- RRF VHF Repeater: Operating on 145.300 MHz with a CTCSS tone of 103.5 Hz, this repeater links to the French Repeater Network (RRF), enabling conversations with operators across France and beyond through IP gateways.
Meshtastic Network Active in the Area
In addition to traditional repeaters, the Le Mans region features several active Meshtastic nodes — a mesh radio system using ISM bands (433 MHz and 868 MHz) in long_fast mode.
Meshtastic uses LoRa modules to send text messages fully off-grid, with no reliance on cellular or Wi-Fi networks. It’s particularly useful in crowded areas like paddocks or rural zones, for close-range communication, field tests, or tactical use.
Operators who are curious or equipped are encouraged to activate their modules and join the local network. Some nodes are fixed, while others are mobile — carried on vehicles or backpacks.
We warmly encourage you to make the most of your visit by connecting with local HAMs, sharing your passion, discovering the region’s radio infrastructure, and maybe trying out new technologies like Meshtastic.
Enjoy the race, happy DXing, and we look forward to hearing you on the airwaves!
