The Mike and Key Amateur Radio Club was initially founded in 1963 under "Pop" Brown, K7LED.

 In 1970, it was reorganized and has remained as one of the most active and viable Radio Clubs in the Seattle area for over a half century. Activity in the Club is as varied as the hobby of Amateur Radio itself. Within the Club there are groups that engage in Public Service, Contesting, DX, VHF/UHF, SSB, CW, Construction/Experimentation, Fox Hunts, Packet, POTA, some Public Service, Traffic Handling and Winlink. While the Club cannot be everything to everybody, it does provide a base of support for most radio interests.

The Mike and Key is known for hosting the largest ham swap meet in the state, each year in March, as well as having one of the largest and most active annual Field Day operations, typically turning in the highest score in the Western Washington section and often the highest in its 6A class.

Within the membership of the club are many of the prominent doers and shakers of Pacific Northwest Amateur Radio. Members are encouraged to be active in the hobby, the club, and the community.
