ABSTRACT:
A method for compensating for frequency shifts during transmission of an RF control signal includes receiving a request to enter a transmission mode from a user. A carrier signal having a frequency is generated and the frequency of the carrier signal is measured. The measured frequency of the carrier signal is compared to a desired frequency to determine if there is a difference between the measured frequency and the desired frequency. If there is a difference, it is determined if data is being modulated on the carrier signal. If data is not being modulated on the carrier signal, a correction is applied to the carrier signal frequency.
