        Hi Tony,

        Yes, the meeting is at the Library in Nashua. Hope to see you there!

            Hi Tony,

             

            If you can make our Field Day meeting on Monday evening, bring your signs then and we’ll figure things out.

              Thanks, Jamey. We’re planning to bring an updated computer controlled satellite station 1.1 to the SOTA tomorrow. Come on out and give sats a try! Anta will have her KX2 setup for FT8 also.

              Looks like its going to be a nice day!

                This is pretty odd. I’d suggest you try testing your LMR-400 into a dummy load to confirm that the cable does not have a problem. Also, check the barrel connector and the connection at your antenna to see if anything is loose or not making a good contact.

                Did you create the coil that caused the high SWR near one of the connectors? If so, you might have a bad connector at that point…

                  And special thanks to you Dan, and to Adam and Gisele and to all of the teachers who helped us so much with our HAB program this spring. It was a lot of fun working with you and your students!

                    Yes, it was right alongside of the trail behind the rock wall on the left. I bet you walked right by it. The toughest part is the last 10 ft or so. Let’s get together for the next one and we’ll hunt together.

                      Hi Doug,

                      A couple of things come to mind –

                      1. Make 100 QSOs on our GOTA station
                      2. Help us earn our messaging bonus
                      3. Help us on Friday/Sunday with Station Setup and Takedown

                      Let me know if you need any help signing up for these things.

                      73,

                        FB Burns. The key is to be able to attenuate the signals enough so you can tell the direction when you get close to a fox. This is especially important with the large fox since it is very strong.

                        The steps that I usually use are:

                        1. Tune 5 – 10 KHz off of the base fox frequency until I get close
                        2. Tune to the 3rd harmonic of the fox frequency until I get closer
                        3. Tune 5 – 10 KHz off of the third harmonic of the fox frequency when I am almost on top of the fox
                        4. While doing 1-3, I place my HT antenna horizontal and against my body to get more attenuation. I turn around to find where the range of angles is when I cannot hear the fox (the null). The center of this range away from my back is usually the direction where the fox is.

                        With these steps, I can usually find our foxes with just an HT and a good whip antenna. Using a yagi antenna and a variable attenuator makes all of this stuff easier but the basics of tuning off frequency, using the 3rd harmonic, and using your body (and the ground) as attenuator are always required.

                        Next time the foxes are out and you want to hunt them, let me know and we can hunt together. You can look and I can coach…
