Hi everyone.Thanks to everyone that submitted information about my vhf and uhf repeater setup.I tried a bandpass cavity tuned to 473.575 between the maxon transmitter and the mobile notch duplexer and it reduced my desense on both the 473.575 uhf and the 70.5875 meg repeaters so it seems I have found the problem .Checking out the duplexers on site ,the only different duplexer was the mobile notch on the 473.575 transmitter as all the others are band pass,band reject so it will be replaced shortly with a bp/br .
Thank You,
