When 1200 was based in Framingham with only 1 kW at night, the big interference was CFGO in Ottawa, ON. They are a sports station using the branding "TSN 1200"I live on the North Shore, and I listen to WXKS Talk 1200 at night.
While it is good clear signal, I can slightly hear a sports station on the same frequency at night.
Does anybody know what station that is?
