Please advise the make and model of your repeater, and its operating
frequencies.
A local repeater once had a similar problem, wherein an AM station's
104th harmonic was beating with the UHF MICOR's exciter output (which is
at VHF) and was then slope-detected by the repeater's receiver.

It is a ham rig. The problem I can see is if the 2 meter side is carrier
controlled the user will have to wait for the repeater to time out to use the

tone to make this work without making the user wait for carrier
