CHP Patrol Car Radio History (8689 words) |
 | CHP Chief E. Raymond Cato approved a number of early radio experiments in the summer of 1931 to evaluate the feasibility of dispatching patrols by radio, with favorable results, however it was not until some years later that radio equipment was formally and uniformly placed into most of the patrol's fleet. |
| The CHP never used AM transmitters in any of their vehicles; the first mobile transmitters were FM and the system performance was significantly better than the AM systems in use by other law enforcement agencies at the time. |
| Evidently the CHP tried to economize by re-using the old Motorola speakers, or possibly RCA was unable to supply a speaker which met CHP standards (the RCA speaker is indeed a poor performer compared to the Motorola). |
