The purpose of this document is to make a small contribution to the evolving knowledge base regarding radio frequenices active within the City of Claremont. Claremont is located in the Pomona Valley within the east end of the County of Los Angeles. All listening guides should be considered, at best, works in progress. Additions, corrections, and suggestions are most appreciated.
Thanks, and happy monitoring.

A "blank" usually means "unknown", but alternate meanings vary for each different field. A "blank" in the "Organization" field might also mean "all services", if there is a single frequency listed. A "blank" in the "Input" field means that this system is most likely a simplex, or direct, system (i.e., not a duplex, or repeater, system). A "blank" in the "Callsign" field might also mean that this frequency is unlicensed (and probably, properly so). A "blank" in the Tone doesn't necessarily mean "none".
The City of Claremont is relatively small. Beat maps, ten-codes, and unit identifiers don't really seem all that necessary.

The Claremont Colleges are patterned somewhat after Oxford. Administrative functions tend to be centralized and academic functions tend to be decentralized. Physically, the campuses are relatively conterminous--logically, the campuses are unique and distinct.

This category is for transmissions that can be heard with a handheld scanner with a rubber duck antenna inside a residence within Claremont, but probably do no originate from within the City proper. Listing these receptions should, in principle, make it easier to discern intended transmissions (by avoiding unintended transmissions), especially on frequencies that tend be densely co-channeled.
