This is a trade advertisement from July 1947 showing WDRC FM's involvement with the Continental Network, a linking of FM stations that distributed programming from Washington to northern New England. The key station in the network was Major Armstrong's W2XMN in Alpine, New Jersey. Franklin M. Doolittle's station on Meriden Mountain in Central Connecticut, was a member as it was in 1942 when Armstrong's station fed the American Network.
