The Maple Valley Amateur Radio Club (MVARC), an ARRL Affiliate club, is a group of amateur radio enthusiasts in the greater Maple Valley area who meet and engage in activities to further the advancement of this hobby for the good of ourselves and the community. 

What is Amateur Radio?

Amateur Radio is a non-commercial radio communication service whose primary aims are public service, technical training and experimentation, and communication between private persons. Amateur Radio operators are commonly called hams. Hams generally communicate with each other recreationally but also provide communications for others at public events or in times of emergency or disaster. Hams are licensed to operate radio transmitters by the Federal Communications Commission, and are assigned call letters. The call letters KC7KEY are assigned to the Maple Valley Amateur Radio Club. Licensing involves taking a test demonstrating knowledge in radio theory and the rules and regulations that govern the use of radio spectrum.
