When WBGT-LP-TV40, 1st went on-air 2/1998, the station owner still used this mic, and his old Marantz PMD-222 recorder, to do the voice-overs for commercials, ID's, promos, PSA's, etc. All went to digital recording a couple years later. I've heard these mics used in Amateur Radio as well, especially for AM Mode QSO's. Makes me think that I'm probably the only one who doesn't have one of these mics. (Got to thank Boomer for forwarding this one to me.)
