regarded as unintentional and largely unavoidable. However, in areas where a US radio station is close to a significantly larger Canadian metropolitan area (or vice versa), true border blasters do exist. An exception to that general rule is KRPI located in Ferndale, Washington. It is owned by BBC Broadcasting, Inc., a Washington state company with studios in Richmond, British Columbia. The station airs a mixture of music, news and talk focused on the South Asian communities in Metro Vancouver. To improve reception of the station within its target market, KRPI applied and received an FCC construction permit to increase its nighttime power from 10 to 50 kilowatts, change the community it served and move its transmitter from Ferndale to Point Roberts, a community adjacent to the Canada–US border. The move has attracted much criticism from the local citizens of Point Roberts and the adjacent densely populated community of Tsawwassen, British Columbia, because it would cause harmful blanketing interference. Another possible exception to that general rule on the Canadian side was CKLW in Windsor, Ontario, across the river from Detroit. Originally licensed as a Class II-B (now Class B) station and always operating in full compliance with the technical specifications and operating rules of its CRTC licence (i.e., protection of the entire Mexican border nights and protection of co-channel Canadian stations days and nights), CKLW's 50,000-watt directional signal blanketed much of Michigan and northern Ohio east to Cleveland days and nights, and south to Toledo, Lima and Dayton in the daytime. American-owned until 1970 as part of the RKO General chain (along with such other top 40 powerhouses as KHJ in Los Angeles and KFRC in San Francisco), it functioned essentially as a Detroit-market station during the 1960s and 1970s. Its Motown-flavored personality Top 40 format made it one of the most highly rated stations in the Midwestern US. The decline of AM radio as a music source in the 1970s, combined with new Canadian government rules imposing domestic ownership of and minimum domestic music content on Canadian-based stations, made it difficult for CKLW to continue to compete for listeners with Detroit-based, US-licensed FM music stations, which offered clean stereo sound and faced no program content or music playlist restrictions. CKLW abandoned the Top 40 format and its efforts to compete in the Detroit market in the 1980s. Today it is a news/talk station aimed largely at an Ontario audience, though
