When the transmitter is in close proximity to the receiver the modulated signal can be overdriven. This condition is referred to as "swamping." By collapsing the antenna and stepping away from the model, you should see this condition dissipate.
Make sure to perform a proper range check and then extend the antenna before operating the model.
FM (Frequency Modulation) uses an analog sine wave to carry data between the transmitter and the receiver. PCM (Pulse Code Modulation) uses digital encoding to transfer information between the transmitter and the receiver.
