Many of them will go into e-waste, but with a century of radios to choose from, some of them are collector\u2019s items. Vintage tube radios like the ones [GarethDaviesLondon] has would go silent, so <a href=\"https:\/\/github.com\/GarethDaviesLondon\/esp32-am-transmitter\" target=\"_blank\">he\u2019s made a small AM transmitter<\/a> to keep them alive.<\/p><div id=\"dev95-2459371709\" class=\"dev95- dev95-entity-placement\"><center>\r\n<script>\r\n  atOptions = {\r\n    'key' : '4ba6b6513c00e0ba76511f798ae56401',\r\n    'format' : 'iframe',\r\n    'height' : 50,\r\n    'width' : 320,\r\n    'params' : {}\r\n  };\r\n<\/script>\r\n<script src=\"https:\/\/www.highrevenueformat.com\/4ba6b6513c00e0ba76511f798ae56401\/invoke.js\"><\/script>\r\n\t<\/center><\/div>\n<p>At its heart is an ESP32-S3, which takes an online radio stream and transmits it through RF generated with a pulse chain on a GPIO. Generating analogue signals from radio to video with a microcontroller is nothing new, but perhaps the more interesting part of this one comes in how he radiates enough from that pin. There\u2019s a 3D printed box with stand-offs designed to take a widely spaced wire coil, which is enough for the vintage electronics to pick up. He makes the point that it may not be legal, but at that power we doubt anyone will notice.<\/p>\n<p>The output on this one is 200kHz for the European long wave band, but we\u2019re guessing a higher medium wave frequency could also be generated.
