KXPA (1540 AM) is a radio station serving the Seattle metropolitan area. It is part of the much larger, nationwide Multicultural Radio Broadcasting network. It is one of 30 stations in owner Arthur Liu's empire of stations, which cater to minority and immigrant communities with programs in their native languages. Most of the stations have multi-language, "brokered" formats. That means they sell their airtime in "blocks," which are usually by the hour. The clients who buy time on the station are free to use it as they please, as long as it fits with federal regulations and restrictions.
