So cool. You can just feel the enthusiasm. Congratulations Brad! <\/b><\/span><\/i>

After 63 years, I was finally able to build a DC receiver of my own design. We achieved “first light” at 7:20P last night. I attached the antenna, speaker, then applied power – and a all of a sudden “Bob’s your uncle!!” There are some things I still don’t quite understand but right now none of that matters as I listen to the sound of clean, crisp CW pouring out of the speaker and filling the room!! Major components – SI5351, SBL-1, TL072 op amp bandwidth filter, LM386 audio amp. I plan to use clk2 of the SI5351 with some Arduino code to create the companion transmitter and CW keyer. Life is good!!!<\/b><\/div>\n
