That is a huge missconception, that statement means that you must immediately turn off your transmitter if you are interferring with the comercial frequency, the comercial trasmitter may keep transmitting until they can fix it! That doesn't mean that they can continue interfering our frequencies forever. If you know who is interfering, then call them up and let them know! They may also be interfering with adjacent comercial frequencies. If there is no action call the FCC!
