We&#39;ll look at the V-I characteristics of germanium and silicon, as well as the lead-sulphide crystal Galena. I&#39;ll show how to design an air core inductor to work in concert with a variable capacitor, which will act as a tuning device for our radio. Our diode will act as a detector, which recovers the audio signal and removes the RF component. This is a great beginner project, a lot of fun to put together, and a good opportunity to show off your build skills!</p> <h3 id="mcetoc_1gn0cou030">Watch the Video:</h3> <p><a href="https://www.youtube.com/watch?v=x9pV6-pk7lk">www.youtube.com/watch</a></p> <p></p> <div style="background:#ffffff;border:1px solid #dadada;margin:0;padding:14px 16px 16px 18px;vertical-align:top;"> <div style="display:inline-block;float:left;padding:0px 25px 8px 0px;"><a href="/challengesprojects/element14-presents/" data-e14adj="t"><img alt="element14 presents" src="/e14/assets/legacy/2021/e14PDCtoDaylight2021.png" /></a></div> <div style="display:inline-block;vertical-align:top;width:70%;"> <p style="margin:0;"><span><a class="jivecontainerTT-hover-container jive-link-community-small" href="/challengesprojects/element14-presents/" data-e14adj="t">element14 presents</a></span>&nbsp; <strong>|</strong> <a class="jive-link-wiki-small" href="/challengesprojects/element14-presents/vcp-program/w/documents/4139/vcp-biography-derek" data-e14adj="t">About Derek</a>&nbsp;&nbsp;<strong>|</strong>&nbsp; <a class="jivecontainerTT-hover-container jive-link-community-small" href="/challenges-projects/element14-presents/dc-to-daylight/" data-e14adj="t">DC to Daylight</a></p> <p style="margin:0;"></p> </div> </div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: tank circuit, tuned circuit, crystal radio, lead sulfide, diode detector, galena, germanium</div> https://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/27964/build-a-simple-radio-using-tank-circuits-and-diodes----dc-to-daylight-22/revision/4Mon, 06 Feb 2023 13:50:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:221e6ac7-e04d-494f-a605-741f482edc82tariq.ahmadhttps://community.element14.com/challenges-projects/element14-presents/dc-to-daylight/w/documents/27964/build-a-simple-radio-using-tank-circuits-and-diodes----dc-to-daylight-22#commentsRevision 4 posted to Documents by tariq.ahmad on 2/6/2023 1:50:00 PM<br /> <p>In this theory-based video, we combine our knowledge of tank circuits and diodes to create the simplest of radios - the crystal receiver.
