Systems and methods for radiofrequency component performance measurement using radiated spurious energy. One example embodiment provides a portable communication device. The device includes a transceiver, a digital signal processor coupled to the transceiver, and an electronic processor coupled to the transceiver and the digital signal processor. The electronic processor is configured to tune the transceiver from an operating channel to a self-quieting channel. The electronic processor is configured to receive, from the digital signal processor, a received signal strength indication based a self-quieting signal received via the transceiver. The electronic processor is configured to compare the received signal strength indication for the self-quieting signal to a predetermined reference signal strength indication associated with the self-quieting channel to determine a signal strength difference. The electronic processor is configured to, when the signal strength difference exceeds a threshold, generate a component failure alert based on the signal strength difference.
