Where is your radio powered from?

If you are pulling any power from under the dash, this can be the cause. Power fed directly from the battery usually prevents this.

Where is your antenna and how is it mounted?

Make sure your radio (both of them) are properly grounded. Do not rely on just the negative power lead as the ground, or the coax shield. I've solved weird issue by running a short ground strap from the radio chassis to the vehicle chassis. Long wires can act like antennas and pick up noise.

Other option is to physically separate them.
