The wide band noise is why we need duplexer cavities on the transmitter, to notch or filter that noise at the rcv freq.? How much noise determines the duplexer needed.
For a clown messing with one of my repeaters I have tuned off 15 kHz and transmitted and the rcvr sq closed giving the impression the clown was not hitting the repeater.? This was with Micor repeater. At 20 kHz did not work. ? If one knows their gear they can do more.
