I have recently being getting pulsing interference on pretty much all bands and have narrowed it down to a general direction after powering off everything and wandering around with a makeshift antenna on the KX3. But I'm not sure what I am looking for now. Much stronger on the beam (3ele StepIr) as opposed to the BigIr vertical The general direction (found by using the beam and the wander method) has a LEB substation and a house or two. So I suppose the question is is there a resource where one can look at screen shots of various types of interference to try and match them up and/or does anyone have any suggestions as to where I should be looking next or what I need to do to pinpoint the source . Here is a location plan from google earth, funnily enough the beam is pointing in the rough direction !
