Update 2-4-2023

The SolderSmoke-DCR is a scratch built radio electronics construction project. It was designed by Bill N2CQR (of the SolderSmoke Podcast and blog) and Dean KK4DAS. It is an intentionally simple Direct Conversion receiver which will be used as a High School hands-on building project to introduce the basic concepts of radio communications.

Please note that the information below is being provided AS-IS and as a way to share my ideas for the advancement of the Radio Art. If you use the information I have provided, you do so at your own risk and must determine if you have the proper skills to do so safely.
