After finding major flaws in a DIY kit, he scraps the schematic and creates his own design from scratch, covering everything from oscillator design and frequency mixing to tuning and final testing. Follow along as he assembles, debugs, and tunes the radio into a working stereo receiver.</p> <h2 id="mcetoc_1j3ol60p40">Watch the Episode</h2> <p><a href="https://youtu.be/qjpECy6tz1g">https://youtu.be/qjpECy6tz1g</a></p> <h2 id="mcetoc_1j3ol6hu81"><span></span></h2> <p><span>Building a modern FM radio receiver is usually straightforward. A single chip like the TDA7000 or a software-defined radio (SDR) module can handle most of the work with just a few supporting components. But where&rsquo;s the fun in that? Using ready-made solutions means missing out on the design process, sourcing unique parts, building prototypes, and debugging problems. To make this project more challenging, Mark decided to design and build a vacuum tube FM receiver without transistors.</span></p> <p><span><em>(Note: Mark did use a stereo decoder IC, though it&rsquo;s optional. For mono audio, it can be skipped. He also included an LM7809 regulator, which of course contains transistors internally.)</em></span></p> <p><span><em><img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/IMG_5F00_1639.JPG" /></em></span></p> <h2 id="mcetoc_1j3qj5f45h"><span>The Kit That Wasn&rsquo;t</span></h2> <p><span>To get started, Mark ordered a DIY tube radio kit from AliExpress. It cost around $220, including shipping, and came with essential components such as vacuum tubes, intermediate frequency (IF) coils, and a variable capacitor. The idea was that it would save him time tracking down parts.</span></p> <p><span>When the kit arrived within two weeks, he quickly found issues: the power transformer was missing, and one resistor was broken. The supplier promised replacements in a later shipment, but the bigger problem was the documentation. The manual was only four pages long, entirely in Chinese. After running it through Google Translate, it became clear there were no instructions on tuning or adjusting the frequency stages. Worse, the schematic had errors: pin numbers were swapped, some required connections were missing, and the PCB contained components not even listed in the bill of materials. At that point, Mark knew the kit was unusable.</span></p> <p><span>Still, it wasn&rsquo;t a complete loss. He had the critical parts he needed such as tubes, coils, and the capacitor. The rest he would redesign himself.</span></p> <p><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/IMG_5F00_1612.JPG" /></span></p> <h2 id="mcetoc_1j3qj5o8pi"><span>Designing From Scratch</span></h2> <p><span>Looking at the salvaged components, Mark concluded he could make the radio work by replacing or adjusting capacitors and resistors while reusing the tubes. With that decided, he set out to design a proper superheterodyne receiver from scratch.</span></p> <h3 id="mcetoc_1j3qj5o8pj"><span>Input Band Filter</span></h3> <p><span>The first stage is a band-pass filter that limits the antenna input to the desired frequency range. This filtered signal is then amplified before being sent to the mixer.</span></p> <h3 id="mcetoc_1j3qj5o8pk"><span>The Oscillator</span></h3> <p><span>Next, Mark designed a Hartley oscillator to generate a tunable sine wave frequency. To tune a station at 95 MHz, the oscillator can be set to either 105.7 MHz (station + 10.7 MHz) or 84.3 MHz (station &ndash; 10.7 MHz). He found that using the lower frequency provided better results with less interference from nearby airband signals.</span></p> <h3 id="mcetoc_1j3qj5o8pl"><span>Mixing the Signals</span></h3> <p><span>The mixer combines the input signal with the oscillator signal, creating several outputs: fInput, fOscillator, fInput &plusmn; fOscillator. The only one of interest is the difference (fOscillator &ndash; fInput), which falls into the intermediate frequency (IF) range.</span></p> <h3 id="mcetoc_1j3qj5o8pm"><span>Intermediate Frequency (IF) Stages</span></h3> <p><span>The mixed output is filtered at 10.7 MHz, which is the standard IF for FM receivers. Multiple stages of filtering improve selectivity. In Mark&rsquo;s build, four stages are used, with the final one incorporating an FM detector.</span></p> <h3 id="mcetoc_1j3qj5o8pn"><span>FM Detector</span></h3> <p><span>Finally, the IF signal is demodulated to recover the original audio. This is done with a dual-diode detector known as a Foster-Seeley discriminator, which produces the audio signal that can then be amplified.</span></p> <h2 id="mcetoc_1j3qjin6op"><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/pastedimage1756460901767v2.png" /></span></h2> <h2 id="mcetoc_1j3qj639to"><span>Reflections</span></h2> <p><span>What started as a faulty DIY kit turned into a rewarding scratch-build. Along the way, Mark revisited many fundamentals of analog design such as oscillators, mixers, filtering, and FM detection. The end result is a working vacuum tube FM superheterodyne receiver, built from a mix of salvaged and custom-sourced components. Despite the frustrations, it was a valuable reminder that sometimes the best projects are the ones that don&rsquo;t go as planned.</span></p> <h2 id="mcetoc_1j3olur7k0"><span>Supporting Links and

6 posted to Documents by cstanton on 8/29/2025 9:50:31 AM<br /> <p>Mark takes on the challenge of building a fully functional FM superheterodyne radio without transistors or SDR, relying instead on vacuum tubes and a custom PCB design. After finding major flaws in a DIY kit, he scraps the schematic and creates his own design from scratch, covering everything from oscillator design and frequency mixing to tuning and final testing. Follow along as he assembles, debugs, and tunes the radio into a working stereo receiver.</p> <h2 id="mcetoc_1j3ol60p40">Watch the Episode</h2> <p><a href="https://youtu.be/qjpECy6tz1g">https://youtu.be/qjpECy6tz1g</a></p> <h2 id="mcetoc_1j3ol6hu81"><span></span></h2> <p><span>Building a modern FM radio receiver is usually straightforward. A single chip like the TDA7000 or a software-defined radio (SDR) module can handle most of the work with just a few supporting components. But where&rsquo;s the fun in that? Using ready-made solutions means missing out on the design process, sourcing unique parts, building prototypes, and debugging problems. To make this project more challenging, Mark decided to design and build a vacuum tube FM receiver without transistors.</span></p> <p><span><em>(Note: Mark did use a stereo decoder IC, though it&rsquo;s optional. For mono audio, it can be skipped. He also included an LM7809 regulator, which of course contains transistors internally.)</em></span></p> <p><span><em><img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/IMG_5F00_1639.JPG" /></em></span></p> <h2 id="mcetoc_1j3qj5f45h"><span>The Kit That Wasn&rsquo;t</span></h2> <p><span>To get started, Mark ordered a DIY tube radio kit from AliExpress. It cost around $220, including shipping, and came with essential components such as vacuum tubes, intermediate frequency (IF) coils, and a variable capacitor. The idea was that it would save him time tracking down parts.</span></p> <p><span>When the kit arrived within two weeks, he quickly found issues: the power transformer was missing, and one resistor was broken. The supplier promised replacements in a later shipment, but the bigger problem was the documentation. The manual was only four pages long, entirely in Chinese. After running it through Google Translate, it became clear there were no instructions on tuning or adjusting the frequency stages. Worse, the schematic had errors: pin numbers were swapped, some required connections were missing, and the PCB contained components not even listed in the bill of materials. At that point, Mark knew the kit was unusable.</span></p> <p><span>Still, it wasn&rsquo;t a complete loss. He had the critical parts he needed such as tubes, coils, and the capacitor. The rest he would redesign himself.</span></p> <p><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/IMG_5F00_1612.JPG" /></span></p> <h2 id="mcetoc_1j3qj5o8pi"><span>Designing From Scratch</span></h2> <p><span>Looking at the salvaged components, Mark concluded he could make the radio work by replacing or adjusting capacitors and resistors while reusing the tubes. With that decided, he set out to design a proper superheterodyne receiver from scratch.</span></p> <h3 id="mcetoc_1j3qj5o8pj"><span>Input Band Filter</span></h3> <p><span>The first stage is a band-pass filter that limits the antenna input to the desired frequency range. This filtered signal is then amplified before being sent to the mixer.</span></p> <h3 id="mcetoc_1j3qj5o8pk"><span>The Oscillator</span></h3> <p><span>Next, Mark designed a Hartley oscillator to generate a tunable sine wave frequency. To tune a station at 95 MHz, the oscillator can be set to either 105.7 MHz (station + 10.7 MHz) or 84.3 MHz (station &ndash; 10.7 MHz). He found that using the lower frequency provided better results with less interference from nearby airband signals.</span></p> <h3 id="mcetoc_1j3qj5o8pl"><span>Mixing the Signals</span></h3> <p><span>The mixer combines the input signal with the oscillator signal, creating several outputs: fInput, fOscillator, fInput &plusmn; fOscillator. The only one of interest is the difference (fOscillator &ndash; fInput), which falls into the intermediate frequency (IF) range.</span></p> <h3 id="mcetoc_1j3qj5o8pm"><span>Intermediate Frequency (IF) Stages</span></h3> <p><span>The mixed output is filtered at 10.7 MHz, which is the standard IF for FM receivers. Multiple stages of filtering improve selectivity. In Mark&rsquo;s build, four stages are used, with the final one incorporating an FM detector.</span></p> <h3 id="mcetoc_1j3qj5o8pn"><span>FM Detector</span></h3> <p><span>Finally, the IF signal is demodulated to recover the original audio. This is done with a dual-diode detector known as a Foster-Seeley discriminator, which produces the audio signal that can then be amplified.</span></p> <h2 id="mcetoc_1j3qjin6op"><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/pastedimage1756460901767v2.png" /></span></h2> <h2 id="mcetoc_1j3qj639to"><span>Reflections</span></h2> <p><span>What started as a faulty DIY kit turned into a rewarding scratch-build. Along the way, Mark revisited many fundamentals of analog design such as oscillators, mixers, filtering, and FM detection. The end result is a working vacuum tube FM superheterodyne receiver, built from a mix of salvaged and custom-sourced components. Despite the frustrations, it was a valuable reminder that sometimes the best projects are the ones that don&rsquo;t go as planned.</span></p> <h2 id="mcetoc_1j3olur7k0"><span>Supporting Links and

5 posted to Documents by cstanton on 8/29/2025 9:48:44 AM<br /> <p>Mark takes on the challenge of building a fully functional FM superheterodyne radio without transistors or SDR, relying instead on vacuum tubes and a custom PCB design. After finding major flaws in a DIY kit, he scraps the schematic and creates his own design from scratch, covering everything from oscillator design and frequency mixing to tuning and final testing. Follow along as he assembles, debugs, and tunes the radio into a working stereo receiver.</p> <h2 id="mcetoc_1j3ol60p40">Watch the Episode</h2> <p><a href="https://youtu.be/qjpECy6tz1g">https://youtu.be/qjpECy6tz1g</a></p> <h2 id="mcetoc_1j3ol6hu81"><span></span></h2> <p><span>Building a modern FM radio receiver is usually straightforward. A single chip like the TDA7000 or a software-defined radio (SDR) module can handle most of the work with just a few supporting components. But where&rsquo;s the fun in that? Using ready-made solutions means missing out on the design process, sourcing unique parts, building prototypes, and debugging problems. To make this project more challenging, Mark decided to design and build a vacuum tube FM receiver without transistors.</span></p> <p><span><em>(Note: Mark did use a stereo decoder IC, though it&rsquo;s optional. For mono audio, it can be skipped. He also included an LM7809 regulator, which of course contains transistors internally.)</em></span></p> <p><span><em><img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/IMG_5F00_1639.JPG" /></em></span></p> <h2 id="mcetoc_1j3qj5f45h"><span>The Kit That Wasn&rsquo;t</span></h2> <p><span>To get started, Mark ordered a DIY tube radio kit from AliExpress. It cost around $220, including shipping, and came with essential components such as vacuum tubes, intermediate frequency (IF) coils, and a variable capacitor. The idea was that it would save him time tracking down parts.</span></p> <p><span>When the kit arrived within two weeks, he quickly found issues: the power transformer was missing, and one resistor was broken. The supplier promised replacements in a later shipment, but the bigger problem was the documentation. The manual was only four pages long, entirely in Chinese. After running it through Google Translate, it became clear there were no instructions on tuning or adjusting the frequency stages. Worse, the schematic had errors: pin numbers were swapped, some required connections were missing, and the PCB contained components not even listed in the bill of materials. At that point, Mark knew the kit was unusable.</span></p> <p><span>Still, it wasn&rsquo;t a complete loss. He had the critical parts he needed such as tubes, coils, and the capacitor. The rest he would redesign himself.</span></p> <p><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/IMG_5F00_1612.JPG" /></span></p> <h2 id="mcetoc_1j3qj5o8pi"><span>Designing From Scratch</span></h2> <p><span>Looking at the salvaged components, Mark concluded he could make the radio work by replacing or adjusting capacitors and resistors while reusing the tubes. With that decided, he set out to design a proper superheterodyne receiver from scratch.</span></p> <h3 id="mcetoc_1j3qj5o8pj"><span>Input Band Filter</span></h3> <p><span>The first stage is a band-pass filter that limits the antenna input to the desired frequency range. This filtered signal is then amplified before being sent to the mixer.</span></p> <h3 id="mcetoc_1j3qj5o8pk"><span>The Oscillator</span></h3> <p><span>Next, Mark designed a Hartley oscillator to generate a tunable sine wave frequency. To tune a station at 95 MHz, the oscillator can be set to either 105.7 MHz (station + 10.7 MHz) or 84.3 MHz (station &ndash; 10.7 MHz). He found that using the lower frequency provided better results with less interference from nearby airband signals.</span></p> <h3 id="mcetoc_1j3qj5o8pl"><span>Mixing the Signals</span></h3> <p><span>The mixer combines the input signal with the oscillator signal, creating several outputs: fInput, fOscillator, fInput &plusmn; fOscillator. The only one of interest is the difference (fOscillator &ndash; fInput), which falls into the intermediate frequency (IF) range.</span></p> <h3 id="mcetoc_1j3qj5o8pm"><span>Intermediate Frequency (IF) Stages</span></h3> <p><span>The mixed output is filtered at 10.7 MHz, which is the standard IF for FM receivers. Multiple stages of filtering improve selectivity. In Mark&rsquo;s build, four stages are used, with the final one incorporating an FM detector.</span></p> <h3 id="mcetoc_1j3qj5o8pn"><span>FM Detector</span></h3> <p><span>Finally, the IF signal is demodulated to recover the original audio. This is done with a dual-diode detector known as a Foster-Seeley discriminator, which produces the audio signal that can then be amplified.</span></p> <h2 id="mcetoc_1j3qjin6op"><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/pastedimage1756460901767v2.png" /></span></h2> <h2 id="mcetoc_1j3qj639to"><span>Reflections</span></h2> <p><span>What started as a faulty DIY kit turned into a rewarding scratch-build. Along the way, Mark revisited many fundamentals of analog design such as oscillators, mixers, filtering, and FM detection. The end result is a working vacuum tube FM superheterodyne receiver, built from a mix of salvaged and custom-sourced components. Despite the frustrations, it was a valuable reminder that sometimes the best projects are the ones that don&rsquo;t go as planned.</span></p> <h2 id="mcetoc_1j3olur7k0"><span>Supporting Links and

4 posted to Documents by cstanton on 8/28/2025 3:53:37 PM<br /> <p>Mark takes on the challenge of building a fully functional FM superheterodyne radio without transistors or SDR, relying instead on vacuum tubes and a custom PCB design. After finding major flaws in a DIY kit, he scraps the schematic and creates his own design from scratch, covering everything from oscillator design and frequency mixing to tuning and final testing. Follow along as he assembles, debugs, and tunes the radio into a working stereo receiver.</p> <h2 id="mcetoc_1j3ol60p40">Watch the Episode</h2> <p><a href="https://youtu.be/qjpECy6tz1g">https://youtu.be/qjpECy6tz1g</a></p> <h2 id="mcetoc_1j3ol6hu81"><span>Why Build Without Transistors?</span></h2> <p><span>Building an FM radio today is straightforward with integrated circuits such as the TDA7000, or by using software-defined radio (SDR). But going back to older technology brings a new layer of challenge and learning. By banning transistors entirely, this project instead uses vacuum tubes to handle amplification, mixing, and detection. This approach reintroduces the fundamental design considerations that early radio engineers had to face while also offering a hands-on exploration of analogue electronics.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu82"><span>The Kit That Didn&rsquo;t Work</span></h2> <p><span>To begin, Mark ordered a vacuum tube FM radio DIY kit that included tubes, coils, a tuning capacitor, and discrete components. While it promised a shortcut, the reality was different. The manual was entirely in Chinese, Google Translate wasn&rsquo;t much help, and critical errors in the schematic and PCB made the kit unusable. Missing parts and incorrect pin-outs meant that simply following instructions was impossible. Instead of abandoning the project, Mark chose to salvage the key components&mdash;vacuum tubes, coils, and the tuning capacitor&mdash;and design his own radio from scratch.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu83"><span>Designing the Superheterodyne Receiver</span></h2> <p><span>The new design followed the superheterodyne principle, with an antenna feeding into a band-pass filter to limit the input frequencies. This filtered signal was then mixed with an oscillator. Mark designed a Hartley oscillator that could generate a frequency 10.7 MHz above (or below) the station frequency. The resulting intermediate frequency (IF) was passed through multiple 10.7 MHz filter stages for selectivity. Finally, an FM discriminator recovered the original audio signal, which could optionally be fed through a stereo decoder for two-channel sound. The main building blocks included resistors, capacitors, coils, tube sockets, and the all-important vacuum tubes.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu84"><span>Assembly and Debugging</span></h2> <p><span>With the schematic complete, a custom PCB was laid out and populated. Resistors and capacitors were placed first, followed by the larger electrolytic capacitors, coils, and tube sockets. Mark soldered each connection carefully, often securing one lead before finalising the second to ensure proper placement. Once assembled, the radio went through a staged testing process. Using a bench power supply with current limiting, the initial &ldquo;smoke test&rdquo; verified there were no shorts. The IF stages were tuned with a function generator and oscilloscope to maximise signal output, while the oscillator was carefully adjusted to ensure proper alignment with broadcast frequencies. Debugging required small corrections, including fine adjustments to capacitors and filter coils.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu85"><span>Results and Reflections</span></h2> <p><span>After careful tuning, the radio successfully received FM broadcasts and delivered stereo audio output. The project highlighted the challenges of working with incomplete kits, the importance of understanding circuit design, and the satisfaction of building something entirely from scratch. Mark plans to mount the finished receiver in a safe enclosure, such as a wooden or Plexiglas case, to make it practical for everyday use. For him, the project was not only about building a working radio but also about revisiting and reinforcing analogue design skills.</span></p> <h2 id="mcetoc_1j3olur7k0"><span>Supporting Links and

3 posted to Documents by cstanton on 8/28/2025 3:49:14 PM<br /> <p>Mark takes on the challenge of building a fully functional FM superheterodyne radio without transistors or SDR, relying instead on vacuum tubes and a custom PCB design. After finding major flaws in a DIY kit, he scraps the schematic and creates his own design from scratch, covering everything from oscillator design and frequency mixing to tuning and final testing. Follow along as he assembles, debugs, and tunes the radio into a working stereo receiver.</p> <h2 id="mcetoc_1j3ol60p40">Watch the Episode</h2> <p><a href="https://youtu.be/qjpECy6tz1g">https://youtu.be/qjpECy6tz1g</a></p> <h2 id="mcetoc_1j3ol6hu81"><span>Why Build Without Transistors?</span></h2> <p><span>Building an FM radio today is straightforward with integrated circuits such as the TDA7000, or by using software-defined radio (SDR). But going back to older technology brings a new layer of challenge and learning.

While it promised a shortcut, the reality was different. The manual was entirely in Chinese, Google Translate wasn&rsquo;t much help, and critical errors in the schematic and PCB made the kit unusable.

This filtered signal was then mixed with an oscillator. Mark designed a Hartley oscillator that could generate a frequency 10.7 MHz above (or below) the station frequency. The resulting intermediate frequency (IF) was passed through multiple 10.7 MHz filter stages for selectivity. Finally, an FM discriminator recovered the original audio signal, which could optionally be fed through a stereo decoder for two-channel sound. The main building blocks included resistors, capacitors, coils, tube sockets, and the all-important vacuum tubes.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu84"><span>Assembly and Debugging</span></h2> <p><span>With the schematic complete, a custom PCB was laid out and populated. Resistors and capacitors were placed first, followed by the larger electrolytic capacitors, coils, and tube sockets. Mark soldered each connection carefully, often securing one lead before finalising the second to ensure proper placement. Once assembled, the radio went through a staged testing process. Using a bench power supply with current limiting, the initial &ldquo;smoke test&rdquo; verified there were no shorts. The IF stages were tuned with a function generator and oscilloscope to maximise signal output, while the oscillator was carefully adjusted to ensure proper alignment with broadcast frequencies. Debugging required small corrections, including fine adjustments to capacitors and filter coils.</span></p> <p><span></span></p> <h2 id="mcetoc_1j3ol6hu85"><span>Results and Reflections</span></h2> <p><span>After careful tuning, the radio successfully received FM broadcasts and delivered stereo audio output.
