I saw something recently on the FCC Enforcement pages about some remote sensors for traffic lights causing interference to a licensed service... turns out the units that were installed were not designed to be sold in the U.S. and were shipped to the installer by mistake. Needless to say, they were taken out of service immediately and replaced with appropriate FCC-certified units. Sounds like you may have run into a similar situation.
