DSL on AM?
Posted on May 4, 2011
Driving to the store starts with 1680 AM (Part 15) clearly on the dashboard, until a block later it fades to background.

Along the way different hums and buzzes come and go at 1680, some probably from power transformers, but others sound hash-like, the way a raw digital signal would sound. After all, the phone company uses AM radio frequencies and higher for their DSL service, so it is reasonable to imagine that some of this gets radiated into the air. Of course the chunk at 1680 would only be a small bit of DSL’s total bandwidth, but interesting to contemplate.
