In case I need to clarify, I'm talking about which dates KPBS conducted membership pledge weeks and membership pledge nights from 1971 through 1974, for instance, because the first membership pledge campaign of KPBS began in February 14 through February 21, 1971 because of June 1970 the station(KEBS-before named KPBS on October 1, 1970) conducted a membership direct mail campaign from June 14, through June 21, 1970 but the rest of the dates of local membership pledge weeks and local membership pledge nights for the rest of 1971, then 1972, 1973 and 1974, I can't remember which date the PBS station conducted those years!!
