I know WSTE 93.7 and WJBR 99.5 are Wilmington DE stations, and WPST 94.5 is a Trenton station. According to the radio-locator map and FCC map. All of 3 stations have a city grade coverage in Philadelphia. Even these stations aren't transmitting from Roxborough Antenna farm. Do these station acknowledge the listeners in the Philadelphia area and not just their local focus area of Wilmington DE/Trenton NJ? Do they have advertisers within the Philadelphia metro?
