    Abstract: A trainable transmitter is described that is capable of learning and replicating both AM and FM signals. The trainable transmitter also has the capacity to learn and replicate RF signals in both the 27 MHz to 40 MHz and the 250 MHz to 450 MHz frequency bands commonly used in European garage door openers. The trainable transmitter allows an individual to input an identification of the country in which the trainable transmitter will be operated such that the trainable transmitter may then transmit the learned signals at the maximum levels permitted for the identified county.
