The results were very impressive, with the second harmonic so low for them, approx 30 dB difference.. that&#39;s probably as good as things can get!</p><p>What &#39;scope are you using, if you don&#39;t mind me asking? The screenshots from the software look nice.</p><img src="https://community.element14.com/aggbug?PostID=22219&AppID=339&AppType=Weblog&ContentType=0" width="1" height="1">RE: Smart Coin Sorter by Inductive Sensing. #02 Experimenting with BJT C-B Colpitts Oscillatorshttps://community.element14.com/challenges-projects/design-challenges/experimenting-with-magnetic-components/b/blog/posts/smart-coin-sorter-by-inductive-sensing-02-experimenting-with-bjt-c-b-colpitts-oscillatorsWed, 20 Oct 2021 13:13:09 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:0f31e081-e1c1-4471-a60e-49979e953a3ascottiebabe1<p>This is fantastic! All the pieces are coming together for this project. Hopefully you tune into one of your oscillator with a portable AM radio waving a coin near the inductor <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-0f31e081-e1c1-4471-a60e-49979e953a3a/contentimage_5F00_1.png:16:16]</span>.
