Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/ I have often seen the need for a low power DIY AM transmitter for the MW band, that would allow me to stream music throughout the house and test and use the tube radios that I restore. I wanted to make it an addition to my ‘under the shelf’ test modules. So, off I went, looking for ideas and inspiration for the design. It didn’t take me long to realise that what was available was either incredibly simple and low quality, or too complex for my needs. Then I found Charles Wenzel’s website (linked below). Reading through the description of his low power AM transmitter project, I realised that I would probably not be capable of designing a better circuit, so I did the next best thing: I wrote to him and asked for permission to do a PCB project build of his design. He kindly approved, and here we are. I made a few changes - as we all do - but the principle is his. The possible errors are all mine. The transmitter complies with the legal power limits and the initial tests prove that the range is more than sufficient for my needs. Building this project also led me to think further about how I can improve on my build, and that is something I will be doing in the future. When I am satisfied that I have a ‘final’ design, I will share the PCBs on PCBWay’s website, should you wish to order your own. Enjoy the video.
