Intro To Ham Radio/Common Misperceptions /What You Can Do In Ham Radio/How To Get Started

I want to make these corrections as given to me by my smart(er) ham friends:   I want to add a correction to the frequency slide. Actually the dividing line between VHF and HF is 30 MHz.   Also on the Propagation slide I misspoke it's the sunspots on the sun instead of the solar flares from the sun that send out electromagnetic energy that ionize the Earth's Ionosphere making for the fun DX Hams enjoy. Solar flares to lesser extent and CME (coronal mass ejections) to a greater extent will disrupt communications on Earth. Hams look at both the K and A index to determine if the propagation is good for worldwide communications. Google these indices to learn more about them. The passing grade for all the tests in 74% instead of 70% as I mentioned in the video. In the Einstein slide I said, you don't have to be a smart guy. So as not to exclude the ladies or the YL's as we hams call them, I should have said persons. Sorry... Finally it's not a hole in the ionosphere per se, it a place in the ionosphere that is not as charged from from the sun's electromagnetic radiation. The term of "MUF" (maximum useable frequency) is used to describe the highest frequency that will support propagation. For instance because the RF waves generated at 14 MHz (20 meters) are larger they are more likely to support propagation when there's low solar activity than the smaller waves of 28 MHz (10 meters). These smaller waves are more likely to escape into space. So when the 10 meter band becomes active we're at a solar peak. Now for those that will speak up here...10 meters will also become active in low solar activity due to their frequency proximity to VHF that gets affected by the weather. Isn't Ham radio fun! 73 K9AT

Great Video Dave! Thanks for putting this out there. I will pass this along.

Thanks Bill.

great job, Dave. Great sounding audio and I appreciate the visuals. Hope you're well.

WUZ up. Great video Dave. 👍
