Dan (N7XDL) shares with us fifty things to do with your ham radio in 2021.
During the presentation, a few links were posted to the Zoom chat. They are included here for ease of reference:

On Saturday, 14 November 2020, MARC and the Taylorsville Amateur Radio Club participated in a "pandemic safe" fox hunt. This was done by having everyone take a bearing from whatever their location was (typically their home, but Neil (KF7PKX) at least took his bearing from his workplace). All of these locations and bearings were given to Dan (N7XDL) who plotted the bearings on a map, which you can see here: Nov14Event_TARC_MARC.
As you can see, not every bearing pointed directly at the fox, which is expected. But if you observe, there were several bearings that did intersect at the approximate location of the fox. For our first try, it was very promising!
We will be participating with Taylorsville for next month's hunt on 12 December 2020. It has not been determined yet if this will be another "pandemic safe" hunt or if we will actually get together in person (maintaining social distancing and wearing masks). Watch this space for updates as we get closer to the event!
Dan (N7XDL) continued his presentation on fox hunts, also known as radio direction finding. This evening's lesson covered topics such as signal attenuation, directional antennas, using a compass to take a bearing, magnetic declination, and plotting bearing lines to triangulate on a target.
UPDATE: The slides from the presentation are now available!
Dan (N7XDL) gave us a brief introduction to "Fox Hunts" or radio direction finding. Our neighboring Taylorsville Amateur Radio Club has been doing fox hunts on the second Saturday of each month for the last couple of months. They have invited us to participate with them this month.
Dan will continue his lesson next week with more detailed information on using directional antennae to track down a hidden transmitter.
A copy of the presentation is included here. Check it out as it includes instructions for building your own "tape measure yagi," a simple directional antenna.
Please consider joining us next week for part two of this lesson! If you need information on how to join the meeting, use the Contact Us link.

Dan (N7XDL) lets us know what we can do to protect our equipment in the event of an EMP or CME. Doomsday averted! Dan's presentation was based on J. T. Smith's paper EMP Faraday Cages That Work.
Dan (N7XDL) gave a great presentation on the dangers and principles behind Electro Magnetic Pulse and Coronal Mass Ejection events.
I will add a link to the slides when I get them.
This presentation sets us up for next month's presentation on what we can do about EMP and CME events.
