"LKeller, not meaning to nitpick, but I believe KLAC was located at the time on the Miracle Mile, separate from KMET & KTTV, not at Metromedia Square. Anyone remember for sure?"
Feel free to nitpick, RicoGregg - I just assumed they were in the same building.
"The great Jim Healy started his signature show with the telegraph sound fx at KLAC, but I'm not sure if it started during the talk radio or MOR era."
According to laradio.com, Healy worked at KLAC from 61 to 65, so he must have started before Two-Way Radio, when they first had an MOR format. He apparently left in 65 before the talk format became really hot. He was at KFWB for awhile, where I don't think they let him do his reports in his signature style. Healy then worked at KABC for a few years, then returned to KLAC during its country days. I was a student working in a Westwood deli in 73 - my boss only listened to jazz (KBCA), except during Jim Healy's sports reports, when the dial was switched to KLAC. That's when I became familiar with his great sports reports. As soon as Jim was done, and the "Ridin' Home with the Jaybird" (Jay Lawrence) jingle started, the dial was spun back to jazz on FM.
I also got the answer to my own question about Lohman and Barkley - also via laradio.com. Roger Barkley was the PD and KLAC, and hired Al Lohman as morning jock in 63 (pre-talk). When MetroMedia bought the station, Roger figured their days were numbered, and teamed himself up with Lohman so they'd both have an act to take to other stations when they got the ax But they stayed with the Two Way Radio format for about 2 years, then left for KFWB in 67, then to KFI in 68 when WB switched to all-news.
