SolderSmoke Direct Conversion Receiver Project -- Video #2 -- Building the PTO/VFO

The response to the SolderSmoke DCR challenge has been terrific -with nearly 7,000 views of the first episode!  Thanks so much for checking it out.  The goal is to convince you that you can build your own receiver and then go get you started on Homebrew ham radio.  We already have confirmation that it can be done!  Congratulations to Peter, VK3PTM and Matthew, KY4EOD who have both completed the receiver.  The boards look good and, even better, they sound great.   Videos and descriptions are here on the blog and on the SolderSmoke Discord sever.   Speaking of the Discord server, we already have a very robust conversation going,  It’s a great place to give feedback and to get your questions answered. Builders are helping builders and we at SolderSmoke are trying to answer as many of your questions as we can.  This is a beginner’s project, so all are welcome.

 

In episode 2 of the SolderSmoke Direct Conversion Receiver challenge we tackle the PTO.  We discuss a bit of the theory, walk through the schematic, and take you step-by-step through building and testing the oscillator and buffert.  By the time we are done we will have achieved JOO!  (the Joy of Oscillation).  And when you build it you will be 1/4th of the way to having build your own 40 meter receiver.
