Many, if not most, of the college radio stations before FM took hold, used carrier current to transmit their AM signal. You always had dead spots, even close to the transmitter.
As late as the early 1990s, a company from Pennsylvania, LPB, was still manufacturing at least 2 carrier current transmitters. LPB stood for Low Power Broadcasting. I saw them in the exhibit hall of a conference of an FM sub-carrier broadcast group at least twice. LPB also made at least one broadcast control board.
