I was asked to help locate the source of RFI at N9CJT and yesterday we
tracked down/identified the source to be from an AT&T (formerly Ameritech)
system and all indications are that the system is VDSL or similar.
For those interested here is the link to a video that documents this case.

Once again the portable flag with DX Engineering preamp allowed us to
quickly narrow in on the property where the RFI was originating and then we
used a small sniffer loop to identify a specific line (cable) on the wooden
utility pole where the RFI was emanating from, and this line turned out to
be an AT&T line. Noel (N9CJT) will now follow-up with AT&T.
Just FYI, and 73.
