ABSTRACT:
A remote control system for use with model aircraft provides a user with the capability of placing the remote control system into a scanning mode wherein a receiver scans through a plurality of channels having a predetermined frequency bandwidth and frequency interference detection circuitry is activated upon detection of interference picked up by the receiver on a channel within the selected bandwidth. Warning circuitry is provided to communicate with the frequency interference detection circuitry for providing a warning signal to a user that interference has been detected. A clear channel is then selected and tuning circuitry permits locking of the receiver and the transmitter on the clear channel so that a user can control the flight of a model aircraft by sending rf signals from the transmitter to the receiver.
