A receiving set is from WDRC, where the carrier wave from WAIU is picked up and transmitted by telephone line to the WDRC control room. Synchroni- zation is then simply a matter of en- gineering detail, and_operation con- tinues without heterodyning. Station WDRC a belongs to a small chain of North Atlantic stations and has obtained permissioin until De- cember 31 to broadcast for two hours nightly on 810 kilocycles (370.2 me- ters), which is the same wave used by WMCA, Hoboken, N. J., the “key” station of the chain. Located 70 miles apart, they broadcast the same pro- gram these two hours on identically the same wave length. This has been suggested by Prof. Doolittle as one of the possible methods of eliminating the use of so many wave lengths by chain_stations, each of which now operates on different waves. Another method of synchronization is the wire control of two or more stations from a common source of radio frequency, a plan which is be- ing successfully’ employed nightly be- tween stations WBZA, Boston, and WBZ, Springfield, which deliver the same programs. The third method is the use of identical or matched crys- tals, such as those now used to keep a station on its wave length, which can be maintained under standard temperature conditions at two or more stations to be synchronized. This method has not yet been tried out. Commissioner Caldwell, a technical man, has been watching these experi- ments with special interest. He has said the commission has no authority to order stations which operate on the same frequency to install mutual synchronizing equipment, but he add- ed that stations which undertake such improvements will be authorized by the commission to operate at closer geographical separations be able to maintain x perior wave lengths. installed 5 miles | Eight musical attractions make up | the program of WRC tonight which will keep the station active continu- ously from 6 until 11:30 o’clock.
