Chris KN4GAH's 100th! SolderSmoke Direct Conversion Receiver

This was the 100th SolderSmoke receiver!     It was really cool to see Chris KN4GAH's  receiver inhaling CW (sbove)  and SSB (below).  I especially like the ink pen markings on the pine board.  FB.  Maybe make note of memorable QSOs heard, or -- later -- contacts made with this receiver.  

Chris is an electrical engineer, so it was particularly useful for us to get his perspective on this project.  We started this at the High School knowing full well that most of the students would spend their careers in the high tech, digital world, and might never again touch a soldering iron.  But we thought it would be good for them to build something like this at least once.  Chris comments on this idea below.

Thank you for putting this all together for all of us and creating such a great community full of knowledgeable and helpful people. I work as an RF engineer and mentor a few junior RF engineers and will be proposing this challenge to them as a learning opportunity. As this challenge provides a lot of insight into how common blocks used in RF designs operate. It is just too easy to go on mini-circuits and find a filter, amp or mixer that meets ones needs. Actually building these components provides valuable knowledge that all us RF engineers should have.

Thanks Chris, Congratulations and welcome to the Hall of Fame!
