his FM system to the FCC. Doolittle was impressed with FM's potential, and in early 1939 announced plans to convert the Meriden experimental high frequency station, now operating under the call sign W1XPW, into an FM broadcasting station. W1XPW's conversion to FM was reported to have been completed as of May 13, 1939, with the station now operating with 1,000 watts on 43.4 MHz. Following an irregular series of test transmissions, the station inaugurated regular programming on October 2, with an initial schedule of 2 to 10 p.m. daily. W1XPW was the third FM station to broadcast on a regular schedule, after Edwin Armstrong's W2XMN in Alpine, New Jersey, and the Yankee Network's W1XOJ in Massachusetts. However, W2XMN was unaffiliated with any AM stations, and W1XOJ was owned by the Yankee radio network, so station publicity referred to W1XPW as the "first frequency-modulated outlet to be built by an independently-owned commercial broadcasting station" (WDRC). On January 4, 1940 W1XPW participated in the first demonstration of an FM over-the-air inter-city relay, which originated in Yonkers, New York, was received and relayed in turn to W1XPW by Armstrong's W2XMN in Alpine, then further relayed to W1XOJ in Massachusetts. Commercial operation In May 1940, the FCC authorized an FM band effective January 1, 1941, operating on 40 channels spanning 42–50 MHz. WDRC, Inc. was issued a Construction Permit for a station on 46.5 MHz that was assigned the call sign W65H. Effective November 1, 1943, the FCC modified its policy for FM callsigns, and the call sign was changed to WDRC-FM. In 1946, as part of a general relocation to a new FM band allocation, the station was reassigned to 94.3 MHz, and the following year moved to 93.7 MHz. In 1924-1925, Franklin Doolittle made the first stereo radio broadcasts, when the broadcasting station he had founded in 1922, WPAJ (WDRC after 1925), was temporarily authorized to broadcast left and right audio channels over two different frequencies on the AM band. In 1952 he returned to dual-transmitter stereo experimentation, when New York City's WQXR paired with its FM sister station, WQXR-FM, to transmit a stereo program that was relayed for rebroadcast by WDRC and WDRC-FM. WDRC-FM's call letters were changed to WFMQ on January 1, 1955. In 1957, the station was purchased by The Concert Network, Inc., a network of FM stations that primarily provided classical music programming, whose affiliates included WBCN in
