I was trying to find an old email from a friend some years back who recalled when KDAY-1580 went 24 hours, but I can't locate it. I seem to recall that he believed it had been sometime in 1968 or '69, but I can't confirm that for sure.
Another friend sent me some FCC files he copied back in D.C. many years ago, with some data on KDAY-1580. The station goes way back to 1946. The first license was issued September 30, 1946 for a 5,000-watt daytimer in Santa Monica, with the assigned calls KXAR, but those calls were never used.
The call letters were changed to KOWL on November 1, 1946, with studios at the Santa Monica Ambassador Hotel. The call letters changed from KOWL to KDAY on May 1, 1956, possibly bcause the station was a daytime-only broadcaster, on the air only during the DAY! Get it? lol
Now for a few technical details. I said that 1580-AM licensed to Santa Monica began as a 5,000 watt daytimer in 1946. According to the FCC files on microfiche, on November 12, 1953, KOWL was granted a C.P. to increase power to 10,000 watts, still a daytimer. A license to cover the C.P. was granted on 3/1/1954.
The FCC file further indicates that after the call change in 1956 to KDAY, the station was granted a C.P. on
May 13, 1964 to increase power to 50 kw-DA, 10-kw DA-2. Somewhere along the line between '54 and '64, they had increased power from 10 kw to 50 kw, to become a 50 kw DA-D, daytimer only. (I'll have to ask my friend for the file again to see when they got 50 kw). There were modifications and extensions to the CP to go 24 hours a day with the 10,000 watts at night DA. Again, I heard that KDAY was 24 hours sometime in 1968 or '69; can anybody pinpoint the date more accurately?
On December 1, 1971, KDAY-1580 was granted a license to cover the C.P. as modified, for 50 kw, DA-2 unlimited. Anyone know when the 50 kw night power went into effect?
I haven't looked up where their transmitter sites had been prior to 1960, but the FCC files show this data:
As of January 8, 1960, they had permission to locate the xmtr at 11600 Palms Blvd. in Los Angeles.
A grant was given by the FCC on 4/25/1966 to have the transmitter at 1532 3rd Street in Santa Monica.
Finally, on March 6, 1968, the FCC was notified that the transmitter site had been moved to 1700 North Alvarado Street in Los Angeles, where the 1580-xmtr has been located since that time.
