A crystal-free radio includes an antenna; a receiver configured to communicate with the antenna; a local radio frequency (RF) oscillator configured to communicate with the receiver; and a clock circuit configured to communicate with the receiver and the local RF oscillator, the clock circuit having an electronic circuit oscillator. The local RF oscillator is a free-running oscillator. The clock circuit is configured to receive a calibration signal via a wireless network and calibrate the electronic circuit oscillator based on the received calibration signal, and the clock circuit is a crystal-free clock circuit.
