Notes

1. College police units start with "87", e.g. 871 or 879. 2. The searchk9.net website has an excellent explanation the Sheriff's "480 Radio System" at http://www.searchk9.net/training/480radio.htm 3. Some noticeable gaps appear on this unofficial radio channel plan on purpose. In most cases these radio channel gaps are simply redundant radio frequencies of other agencies which are listed on their own page.
