[Elecraft] Broadcast band interference

[w0ebb at juno.com]

I'm having occasionally issues with broadcast band interference on my KX3, SN. 564.  It seems to come in at random times throughout the day on multiple bands.  All of my antennas are tuned to the band I'm using them on and not just a random wire type.  I tend to see the problem mostly on 30, 20 and 17 meters. Any reason I'm getting this type of interference and is there any way I can take care of it or block it.  Sometimes it's loud enough to be a problem when trying to copy weak CW signals.
