Yes. Mainly as station alerting only.
I didn't know that LA used 33.700. I thought 33.86 was the one that boomed in around Western PA back in the day. Anyways it was neat. I know when I was a kid living up that way we used to pounded by an EMS dispatch on 33.700 out of Seattle.
I used to drive across the US a lot. I remember sleeping in Las Vegas with scanner on Public Safety search on one night. In the morning I woke up to Westmoreland, Fayette, Cambria, Indiana, Washington, Armstrong, Beaver, Mon-Yough, McCAndless, Shaler, Erie, Crawford, Mercer and everyone else that was on low-band then, booming in!
