For those who are unfamiliar with it, here is some information about the IARU/NCDXF beacons (see link), and the subject of interference (see attached text below). Link: http://www.ncdxf.org/Beacon/intro.html
73---Bonnie KQ6XA ===="Beacon Interference"==== (Excerpts from the IARU/NCDXF website) "The major interference problem for beacon listeners occurs on the twenty meter frequency of 14100 kiloHertz. The IARU/NCDXF beacons have been on this frequency since 1979. The frequency was established before the tremendous advances in the popularity of the digital modes occurred and today the frequencies on both sides of 14100 kiloHertz are full of digital signals. On the ham bands, no station has a legal right to exclusive use of any particular frequency. However, as the digital-mode signals began encroaching on the beacons, both the IARU and the ARRL incorporated into their official band plans the idea that the frequencies between 14099.5 and 14100.5 should be kept clear to protect the beacons at 14100.0. Although these band plans do not have the full force of law, there is general agreement that a properly operated amateur radio station should normally operate within such band plans and the vast majority of digital operators do so... If one listens for the beacons with a receiver whose bandwidth is designed for voice reception, the 2.8 kiloHertz bandwidth typical of such receivers will inevitably receive adjacent digital signals as well as the beacons. When this happens, the resulting interference should not be blamed on digital operators so long as their signals are more than 500 Hertz from the beacon frequency... Unfortunately, not all digital operators are familiar with fact that the official band plan for twenty meters calls for keeping the frequencies around the beacons clear. Furthermore, some digital operators do not realize that their transmitted RF energy occupies frequencies which are different from the frequency which shows on their dial..." http://www.ncdxf.org/Beacon/BeaconInterference.html .
