As  L.A. county contained a legacy station on 1600, in Pomona, I would 
expect  this station's frequency was at least 1640.

In Dallas, Texas ,  WRR was in charge of all Dallas police & other  
communications from the beginning in the 1920's tilll about 1969, we had a  Western 
Electric 303-C 1 kW.  operating on 1714 kHz.  on a slant wire  on the old WRR-AM 
Auxiliary tower in Fair Park.  The call sign was  KKB-364.  It ran until the 
mid 1960's.    The had a bunch of  old fixtuned tube radios that were used in 
warrant servers cars etc.  They  had call numbers assigned as did all the 
Dallas Radio stations.   If  you heard on the police radio your stations one way 
call number and the phase  call 531.  That meant call the police dispatcher.
 
Origionally the 1714 kHz. was the base station and the cars talked back in  
on 35 mHz. AM later everything migrated to 45.66 mHz. FM and later to a 12  
channel full duplex  460 mHz. system.  That was over 35 years  ago  I guess 
Dallas now has some type of trunking system.
