This has the symptoms of RFI from high speed internet services offered by
the cable TV companies. Many cable companies are now using the HF frequency
bands for subscriber uplinks on this service. I recently had a major problem
here with Cablevision wiping out the 40 meter amateur radio band.
You will have to do some more tracking of signals but put leakage from cable
TV internet service on your list of suspects.
Pretty easy to find, if so. Make a sniffer for a portable SW receiver and
take it out to the box where cable comes into the house. There should be a
definite peak as you put the sniffer coil close to the box.
