Abstract
An apparatus and method to use the temperature of a transmitting radio to prevent transmission of radio waves outside of an assigned frequency band. More specifically, if a transmitter exceeds a specified temperature the transmitter will be automatically disabled to prevent temperature caused frequency shifts outside the approved frequency transmission band for the transmitter. The transmitter has a temperature sensor that senses temperature and compare the operating temperature against a preselected temperature limit. It the operating temperature either is too hot or too cold the transmitter will be disabled and will not transmit until the temperature falls or rises to an acceptable level.
