Here’s Mr. Carlson demonstrating an old Gates AM broadcast transmitter. There are quite o few old AM BC transmitters still on the air, used by hams on bands close to the AM BC band . (Mr. Carlson is a ham and uses his on the air. ) If you listen around 3.885 Mhz you may hear one (even if it’s AM, it’s more likely to be old ham equipment than BC, but if you hear a wideband well modulated signal listen for a bit and you may hear what type of equipment you’re listening to, or just google the callsign you hear and you’ll probably see a personal page … )
