Lesson 3 Part 3 - How To Fix Just About Anything Electronic!
🕑 Added 2023-01-16 17:42:41 +0000 UTCIn this video: "Learn how to troubleshoot oscillator circuits properly." Learn about "Circuit Loading," and how it affects the equipment you are troubleshooting. See how an emitter follower buffer works to stop oscillator drag when circuits are being tested. See how a normal oscilloscope probe can make your measurements wrong! See the affects of a decoupling capacitor removed from circuit, then replaced. Learn how to tune a Hartley oscillator in many different ways, and much more!
NOTE: If you're using the information in this video or attachments, building the circuits, and using your own test equipment, or any equipment, you are doing so at your own risk. If you do not understand this, or do not agree with this, Do Not use this information, IE: (The information in the video, and in any attachments provided,) and do not build anything.

No bites? decoupling cap 10E5 pf removal and wallah! Smooth 22Mhz with 200% gain! NOT what happened to Carlsons at 21mins into "Part 3" https://youtu.be/1Jl37iqxiTU

3rd build's the charm. Seeing 23Mhz. But, very jagged without a core in my coil. Ideas why it's not a smooth sine wave? https://photos.app.goo.gl/nLaJ3ozdtGWcSNWE6
