Partly in an effort to make ammends for some overly harsh comments I made about the podcast's approach to the "rejuvenation" of old radios (it turned out to be overly digital for me) I appeared earlier this month on the Ham Radio Workbench podcast. It was a lot of fun. They are a great bunch of guys. And I think we had a great discussion of homebrewing and HDR in the modern era. We talked about Jean Shepherd, Farhan, G-QRP, kits vs. homebrew, homebrew vs. commercial, SDR rigs, the sBITX, the NORCAL 40, the Gilbert Cell Mixer, our experience (bad) trying to get high school kids to build a DC receiver, and many other topics.
Thanks George! And thanks to the entire Ham Radio Workbench crew!
Remember, SolderSmoke has issued a challenge to the HRWB team: We challenge them to build the 40 meter Direct Conversion receiver that we designed for our local high school. We urged them to build it the way we designed it -- avoid the temptation to substitute stages, or use pre-fab circuit boards. Build the four stages Manhattan style and get the receiver working on 40. Here are the details on how we did it. Here are our building documents:

The challenge has been issued. The gauntlet is on the ground. Go for it HRWB! Put those workbenches to use!

Looks like Mouser has at least 5,504 on-hand of the transformer. :)
