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) 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.
