Depends largely with RF environment.  Due to location of antenna and station, a strong RF field may exist at the station location.  Separation between the two is our friend.

I connected a cheap set of powered pc speakers to the KX3 but I hear distortion through the powered speakers when transmitting with the KX3 and KPA-100 connected to a KPA-500. Has anyone found a high quality powered speaker to connect to the KX3 that doesn’t distort when transmitting?
