Forget about using white boards, paper and
books. I found using SSDR on a 42” screen this past week was a great tool for to the students to learn from. I used the 80 meter band in the demonstration as the other bands were quite. I started out with the band edges at both ends, and all of the signals on the waterfall were amazing for them to see what was going on. Pointing out SSB, AM, and CW Signals. Explaining the 6khz bandwidth rule, was real easy to do, and how more operators can work together on SSB on using 3khz. I showed them how filtering of the signal works when two stations are side be each, and then the dreaded CW carrier showed up, and how the ANF button worked to get rid of the tone noise. The student’s visual experience was gratifying. Thanks to Flex for making this part of the hobby easier for us instructors.
