That’s just plain ordinary


That’s just plain ordinary dropout – not interference, just the signal strength diving down and recovering quickly. Just a burt of noise, and very, very common. I’m assuming the receiver is a battery operated one? Although these are diversity receivers, using the aerial for one channel and the screen of the audio cable for the other channel, they are close together, so if the presenter walks into a null, then it’s probable both aerials will be in the same path. You can improve the problem by putting the receiver closer to the transmitter and running a long XLR cable, or simply moving the receiver and zoom closer wired together. The old maxim holds true – a two thousand dollar radio system is nearly as good as a ten dollar piece of cable!
