It confirms the comments I made earlier when we started to think about 600m possibilities. I suggested that we avoid 500kHz exact because of this possible problem. I talked to Finbar tonight and he said he had not heard it. So that is why, but he and some of his contacts do hear different signals around 500kHz from their TV sets. It seems that the step changes may be a fuction of a digital set ?? I did hear a two tone signal nearby. I think I have a capture of it.
