Indeed it is because they did not file their license renewal. According to the database, the license expired August 1, 2004. The last renewal listed was from 1996. Search for DWSLV in the FCC's AM broadcast station query.I know the FCC periodically will delete a license should the station forget to file. In some cases, the station can get their license back. In my area, station KDPS filed its license about 4 months after it expired and after the callsign had been deleted. The FCC approved the license renewal (with a fine of course) last week. They weren't even off the air for more than a few weeks having applied for an STA as soon as they heard their license was deleted.WSLV might not be so lucky since it has now been two years. I'm sure they will file a renewal and apply for an STA, whether or not the FCC grants it remains to be seen.
