More than likely, the sweeps you're referring to are created by this monster... http://www.raytheon.com/capabilities/rtnwcm/groups/public/documents/content/rtn_bus_ids_prod_rothr_pdf.pdf Every 18 minutes, the Department of Homeland Security is sweeping the ionosphere from three locations as it triangulates illicit drug activity involving ships and aircraft. Here in the Southeast, we experience +40dB/S9 sweeps starting around 6MHz up through roughly15 MHz from each of three synchronized ROTHR sites located in Virginia, Texas, and Puerto Rico. The sweeps are constant and always upward moving in frequency. I have developed an almost Pavlovian fear of the blast every 18 minutes on 40 meters. If one has a pan adapter connected to their receiver, the sweep can be seen marching across the screen. The next time anyone thinks someone is simply checking the SWR of their antenna by sweeping their transmitter's VFO, the interference just may be coming from DHS. The 18 minute interval is a dead giveaway.
