I'd buy a pair of those RF glasses! Might scare the bejesus out of us if we saw what was really sloshing about all around us.<br /><br />I agree with your statement about it being a great time to be a ham. Of course, I've been licensed since 1963 and, with the exception of one 12-year period of relative inactivity, it's always been a pretty good time. But with the possibilities out there, it's especially a good time right now.<br /><br />Drop in often...<br /><br />73,<br /><br />Don Keith N4KC<br />www.n4kc.com<br />www.donkeith.com<br />www.facebook.com/donkeithAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1775853671332053099.post-76233037487765531412009-09-09T12:55:38.033-05:002009-09-09T12:55:38.033-05:00On my first pass through your blog I failed to not...On my first pass through your blog I failed to notice you used the word "ubiquity". Had I caught that I would have refrained from using the word in my comment post. I just got excited cuase I have been waiting for the opportunity to throw that one in someplace.<br /><br />Cheers,<br />Mike KD8JHJAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1775853671332053099.post-38637912917444967432009-09-09T11:48:17.834-05:002009-09-09T11:48:17.834-05:00Hi Don,
Great Post! The electromagnetic soup sub...Hi Don,<br /><br />Great Post! The electromagnetic soup subject is one I have spent way too much time thinking about. We each try to visualize in our minds what radio spectrum energy would look like if we could see it. Picture the ubiquitous broadcast tower with the concentric rings radiating outwards.<br /><br />My fantasy invention is a set of goggles that when worn allows the user to see radio waves. Frequencies would be diffentiated by color and or texture while still allowing observation of one's solid physical surroundings. The unit would have the usual features like bandpass filters and gain or sensitivity controls. I don't know of many practical uses for somthing like this but I think it would be fun to walk around the neighborhood. Of course the RF goggles would be prohibited from use in foxhunting (transmitter hunting). <br /><br />I read a lot of sci-fi while growing up. Amazing how so much of today's technology was yesterday's Buck Rogers. So needless to say my wheels never stopped turning.<br /><br />Concerning amateur radio I now almost always boot up the laptop in the shack whether I plan to operate digital modes or not. The spectrum display or "waterfall" provides a unique window into the invisible world of RF. It gives us a visual idea of how we manipulate radio signals with our equipment. I like watching two operators on CW to see how well they have zero beat or not. I recently installed a CW filter in my rig and it was cool to turn the filter on and off and see the bandpass edges right were they were supposed to be. This feature of my ham software has really helped me to understand some aspects of radio theory. It is a great time to be a ham. <br /><br />It sure is curious how the multitude of radio signals out in free space can do their thing and for the most part not interact with each other. And as you pointed out there are more and more of them every day. Maybe we will reach a point of saturation when free space can no longer manage the flow without adverse reaction. ???<br /><br />Sorry for the essay, but you asked for it.<br /><br />73 Mike KD8JHJAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1775853671332053099.post-2375420869448621472009-09-05T13:13:39.480-05:002009-09-05T13:13:39.480-05:00Wilson, thanks for dropping by and leaving a post....Wilson, thanks for dropping by and leaving a post.
