This is a really cool interview. Both Mitch NK3H and Charlie NJ7V are members of the SolderSmoke Direct Conversion Receiver Hall of Fame. Mitch has built a dual-band superhet rig, which is the subject of this interview:
Here is a video Mitch did about his SolderSmoke DC receiver:
Mitch also built the Michigan Mighty Mite. And he did an SSB version!
Mitch is a very interesting guy. He was a professor, he worked in biotech, founded his own company which was funded by venture capital, later retired, got interested in astronomy, and came to ham radio at the start of the pandemic. Wow, great stuff.
In Charlie's video, Mitch provides a lot of good explanation of his experimentation process. I had to chuckle when Mitch pointed out that he did NOT invent the Colpitts oscillator. Good point Mitch!
Mitch credits Pete N6QW as one of the people who helped him design his superhet transceiver. He also mentions Farhan VU2ESE, Alan Wolke W2AEW and several others. FB. And he credits SSDRA, EMRFD and ChatGPT. Mitch also likes the videos of the IMSAI Guy.
Mitch has already made 50 contacts with this rig.
Mitch makes excellent use of microcontrollers and digital VFOs. He provides great info on the speed and cost of various sources of commecial PC boards.
Quote of the day from Mitch: "Electrons don't care how pretty or ugly your board is!"
Mitch concludes with a quote from Pete N6QW: "You gotta know stuff to do stuff." But Mitch adds to this an important coda: "But the process of doing it is the learning experience." Exactly right Mitch.
Thanks to Mitch and Charlie for a really great video: https://www.youtube.com/watch?v=wK_EVt5iAQ4
