Which of the amp's antenna outputs are you using? When the KPA1500 is switched off the antenna is internally defaulted to connector number one. So if the noise is coming in via an antenna connected to number two, it should drop when power to the amp is turned off.

Today as I was shutting down my station I turned off the KPA1500 first, and my noise dropped from S7 to S1 instantly. I turned the Amp back on and the noise came back. Have any of you ever observed this?
