Rounded Rectangle: KD7NRQ Homebrew 813 Oscillator Site

 

 

 

  This site contains all the information one would need to build a 150 watt 40 meter crystal transmitter.  This circuit was built based on information provided kindly by Ken's (W7EKB) website.  On that site you will find the basic schematic, the RCA Ham Tips, and examples of W7QQQ's transmitter.  My goal was to create a 1 tube 813 transmitter.  I did it and it works great!  Below I  have links to my design and plenty of pictures to get ideas from.  I also included a links page that may be helpful for you to acquire parts for your project and also has 813 RCA technical sheets. I hope you enjoy! Be safe!Rounded Rectangle: Transmitter
