My brother, Robert Neufeld, amateur radio operator N3AU, who also has pretty much every commercial radio license and is a lifetime electronics hobbyist, is going to host a zoom technical discussion each Thursday night at 8 pm eastern time. He plans to have it run around an hour +/- depending on what questions people have.
You can email him at rjneufeldmd@gmail.com if you’d like information about the meeting.
The first session is tonight, March 25, 2021.
