Re: KOGO - San Diego/old studios, first DJ?
Ha ha, yes, my fault I suppose. I may start a new thread later on some or part of this. Yeah, Fred Christian was playing records over his ham station on Harold Way in Hollywood. That was September of 1920. Also, that was on his ham station, and all amateur radio operators at the time had to take turns on 200 meters, about 1500 kilocycles/khz. on the AM band at the time.
Was Fred Christian the first DJ, or person to play phonograph records over the air? No. First of all, in April of 1920, experimental radio station 6XD was licensed for the Western Radio Electric Company. Their station was broadcasting from 550 South Flower Street in Los Angeles and was on the air several months before 6XDZ. According to an issue of Pacific Radio News that year, 6XD was heard on 920 kilocycles and was broadcasting phonograph records from nearby Richardson's Music Shop, as they furnished the latest Victor Records to the little radio station that put out 2 and a half amps, or about 50 watts. Was there a person announcing the records on the air, or were they simply playing the records and giving station IDs? We don't know the answer and have no evidence to say if the station announced the songs after they were played.
But, we know that 6XD was likely the first experimental radio station on the air in Los Angeles, before ham station 6XDZ. Also,
in December of 1921 6XD became station KZC on 360 meters/833 khz. and in February 1922 changed calls to KOG, the first station call letter change in U.S. broadcasting history.
So, who was the first to play records on the radio? Other hams also played music and records on the air before 1920. But, Prof. Mike Adams of San Jose State University says 16 year old Ray Newby of Stockton, CA was the first to play records on the radio, as a student of Herrold College of Wireless in San Jose, California in 1909, under the supervision of Charles "Doc" Herrold. Newby appeared on the TV game show "I've Got a Secret" in 1965, as his secret was, "I was the world's first radio D.J."
As for modern disc jockeys, possibly Al Jarvis of KFWB with his Make Believe Ballroom in 1934 on KFWB, as he played records, but made it sound like they were played by live bands and orchestras. An announcer at KMPC in Beverly Hills, Martin block listened a lot to Jarvis and took the idea to New York, where he copied it and used in on his own show on WNEW with the same name, in 1935. But of course, the rise of the DJ came with post-war radio after television became big and radio survived with the DJ music programs and Top 40, etc.
