Ham Radio General Class License Lesson 5.1, Signal Review

Here’s your video introduction to ARRL General Class License Manual Lesson 5.1, Signal Review. The section is primarily review, but let’s spend a few minutes walking through the vocabulary so the concepts are firmly in mind before proceeding to the subsequent sections. This video covers continuous wave (with a brief excursion back to the spark era), carriers, modulation, modes, AM, and Single Side Band. Included is an actual on-the-air demo with a spectrum scope to look at an AM signal showing the carrier and both sidebands, and how each sideband contains all the information. A demonstration follows with just single sideband modulation. The video concludes with an introduction to angle modulation modes such as FM and phase modulation.

    Dave, I find your videos very helpful. The explanations are understandable and practical. I especially get great benefit from the actual demonstration of your equipment. I haven’t access to an HF rig (yet) and it is great to see how the theory really works and sounds.

    Nice, I get a bit more out of these when you go into it. The math videos did not do much for me.
