I certainly don't get any interference from my own ADSL - 2Mb fixed rate with the router and telephone lines right in the upstairs shack. Neither my 500kHz vertical in the garden or my (untuned) longwire which runs right into the shack pick up anything. But there are no overhead lines here, it is all underground. When I first went to broadband I specifically listened on 136kHz, 73kHz and all the HF bands and I have yet to find anything which I can attribute to the ADSL. It is OK the other way as well, it works solidly when I transmit on 500kHz, HF or whereever. I rather suspect your noise is not ADSL, more likely switch mode psu QRM. 73 Dave G3YMC http://www.davesergeant.com
