Don, I will let Scott or Kevin confirm this but I think you are correct in that often times the transmit channel element is strapped to oscillate all of the time. Nothing wrong in doing this and it is not normally a problem unless you are very close to the repeater (usually within a few feet).
If you reach inside the Micor cabinet and pull out the transmit channel element the source of keying your cross band radio should go away. The quick fix is more distance (try another 10 feet) or add more shielding between the repeater and your cross band mobile if possible.
