    Abstract: A trainable transceiver for controlling a remote device includes a transceiver circuit, a user input device, and a control circuit. The transceiver circuit is configured to receive a first activation signal from an original transmitter and configured to transmit a second activation signal. The control circuit is coupled to the transceiver circuit and the user input device. The control circuit is configured to format and transmit the second activation signal, based on the first activation signal, in response to a user input received at the user input device. The control circuit is configured to reduce a duty cycle of the second activation signal relative to the first activation signal and increase a radio frequency power of the second activation signal relative to the first activation signal, while maintaining, for the second activation signal, an average radio frequency power over a predetermined amount of time below a predetermined limit.

    Abstract: Methods and systems for modifying a carrier frequency for a trainable transmitter may include receiving a request to transmit a control signal from the trainable transmitter to a receiver. A transmission of a first control signal may be made using a trained carrier frequency and a control data. At least part of the carrier frequency may be shifted by a frequency increment. A second control signal may then be generated using the carrier frequency shifted by the frequency increment and the control data. The second control signal may then be transmitted.

    Abstract: A trainable transceiver is provided for a vehicle for transmitting signals to a device remote from the vehicle. The trainable transceiver includes a programmable oscillator for generating a signal having a selected reference frequency; an RF transceiver that receives an RF signal during a training mode in order to learn characteristics of the received RF signal, and transmits an RF signal to the remote device in an operating mode where the transmitted RF signal includes the learned characteristics of the received RF signal, wherein the RF transceiver receives the reference frequency from the programmable oscillator and uses the reference frequency to learn the characteristics of the received RF signal and for generating the transmitted RF signal; and a controller that, during the operating mode, selects frequency control data representing a frequency and selects the selected reference frequency for the programmable oscillator as a function of the frequency control data.
