There are three possible solutions that can be used for any type of interference problems. The first, and most obvious, is to reduce the magnitude of the interference signal by moving away from the interference source. Another option is to prevent the interference signal from getting to the receiver by using an RF-filter if the interference is coming through the input, using shielding if the interference is coupling through the air or using a twisted pair of wires if they are long and by necessity have to be connected to the input of the amps. A final possible solution is to make the receiver more robust by choosing a better designed in-amp or differential amplifier.
