About CBRA
The Chesapeake Bay Radio Association is a nonprofit amateur radio club serving Cecil County and the surrounding region through radio communication, technical education, emergency communications, repeater service, and public-service minded activities.

The fire tower and repeater infrastructure are part of CBRA’s long-running radio-service identity.
Radio, public service, and technical education since the early 1970s.
The Chesapeake Bay Radio Association was founded in the early 1970s by radio enthusiasts with roots in Civil Defense communications, local CB radio activity, and practical community communications.
The club first placed an amateur radio repeater on the air in Havre de Grace. In the early-to-mid 1980s, the repeater was moved to the Woodlawn Fire Tower, expanding coverage across Cecil and Harford Counties and strengthening the club’s public-service communications role.
Through hurricanes and other communications challenges, CBRA members have supported emergency and health-and-welfare traffic. The same spirit continues today through repeaters, nets, meetings, mentoring, training, public service, and hands-on technical learning.
