A wireless electronic tracking system employs transmitters attached to moveable target items that send continuous analog radio frequency (RF) digitally-coded signals at prime number differentiated time intervals to a base receiver. The coded signals carry transmitter and base unit identifiers, low battery and attachment status information. The base unit periodically scans using an omnidirectional antenna to determine distance and azimuth for multiple active transmitters, alerting an operator to any status alerts, such as `out of range` status determined by signal strength. The operator can switch to a higher gain, directional antenna to search for an errant target transmitter, or simply to check on the whereabouts of any given target item. Because the movable target items need only transmit, the transmitters can be physically diminutive and unobtrusive to the target wearer, making the system practical for tracking people (e.g. geriatric or juvenile, for assistance or to deter leaving group members behind), animals (e.g. pets, livestock) and even inventory (e.g. especially expensive items that shouldn't move from a given spot in a retail setting).
