50 to 54 MHz, the 6-meter band, presents unique propagation characteristics, often referred to as the "Magic Band" due to its sporadic E, tropospheric ducting, and F2 layer propagation potential. This resource specifically addresses repeater operations within this frequency range, focusing on the regional coordination efforts in British Columbia and Washington State. It highlights the standard -1.7 MHz transmitter offset commonly employed in these areas for 6-meter repeaters, a critical detail for proper station configuration. Amateur radio operators utilizing 6-meter repeaters in this region will find the mention of a typical 100 Hz CTCSS tone particularly useful. This tone, often called a _PL tone_ or _sub-audible tone_, is essential for accessing many repeaters and filtering out unwanted signals, ensuring clear communication. The resource also points to the _BC Amateur Radio Coordination Council_ (BCARCC) as the coordinating body, emphasizing the importance of coordinated frequency usage to prevent interference and maintain efficient band operations.

This resource facilitates searching for stations by various criteria, including callsign, operator name, city, and postal code. Search results typically display the operator's identity, full address, email contact, and personal website link, if available and publicly listed.

It provides a direct mechanism for operators to request modifications or new insertions of their data into the online nomenclature, ensuring current and accurate listings. The service is a fundamental tool for QSLing, locating fellow hams, and verifying contact information within France. Authored by _F6BIG_, the callbook is a key utility for French hams.
