[Spooks] Numbers Stations in Los Angeles between 9am and 12 noon ?

[Nicholas Gessler]

I'm teaching a course which includes a section on espionage.
I have the Conet CDs, but would like to tune in a live Numbers Station
in Los Angeles during my class which meets Tuesdays & Thursdays
from 9:00 a.m. until 12:00 noon, Pacific Time.

Can anyone help me identify a Numbers Station which is receivable
here during those hours?  So far I've been unsuccessful in finding one.

Many thanks,
Nick
