[na0tc] This Saturday, 285 TechConnect meeting 10 AM

[285 TechConnect Radio Club - Morrison, Colorado]

Even though it is Labor Day weekend, the 285 TechConnect radio club will meet this Saturday at Inter Canyon Fire Station #3 at 10AM

As always please bring in or tell us about your latest projects for show and tell.  One the agenda we will get an update on the Tech Fest that is only a couple of months away.

The topic for the meeting will be Smith charts. The plan is to create a crude Smith chart using our basic knowledge of transmission lines to understand how the chart works. Then using real charts and software solve problems. Finally, test the solutions using a vector network analyzer. The process should give us a better understanding of what goes on in the complex world of transmission lines.

Smoke or No Smoke: To improve the efficiency of a magnetic loop antenna the diameter of the tubbing use to make the loop is doubled. The capacitor for the original antenna was just adequate. Smoke or no smoke?
