Its called adjacent channel rejection, if your unit is not properly aligned this can occur. PL or not if its poor on rejection then you get bleed over, the same kind of thing that happens when a trucker goes by pushing excessive wattage from his CB and bleeds all over a poorly shielded amplifier or TV.
This can also be a result of the shielding of your feed line to your repeater being compromised. These symptoms also cause desense on the receiver.

What is the use of a PL tone if it isn't able to block out the co- channel users? Is it because the co-channel user is transmitting with more power and is able to break the PL tone? What are the expectations of a PL tone? When does it work and when does it not work? Are there other devices that can help all? Thanks in advance!
