The Chelsea Amateur Radio Club announces the “I Hate Cookbooks Guide to Amateur Radio Electromagnetics” training. This is designed for the amateur with little electronics knowledge but an intense desire to upgrade to the General or Extra amateur classes. For those intimidated by mathematics, brief introductions to such things as imaginary numbers and normalized impedances…

Many amateurs in Washtenaw and peripheral counties frequent an informal net each weekday morning from about 8AM to 8:30AM on the Washtenaw repeater sitting on the 145.150 MHz amateur frequency. This repeater is tax-payer funded and has a fantastic reach with its antenna sitting high atop a tower that is located at nearly the highest…

At last night’s monthly meeting of the Chelsea Amateur Radio Club (7-12-2022, WD8IEL), it was decided that the Chelsea Amateur Radio Club would sponsor weekly electromagnetic training sessions by Zoom. This will be open on a global scale to the amateur public. Initially, Wes Cardone (N8QM) will be the sole presenter, but volunteer presenters are…

I just realized how long ago Field Day was, and how long it’s been since I’ve posted! Safe to say I’m overdue here, but I wanted to do a quick shout-out to all of those who attended field day and did so much to make it happen. I’m sure I’ll miss someone in my call…

What distinguishes “impedance” from “characteristic” impedance? A 1 foot length of RG-8X coax has a characteristic impedance of 50 Ohms. But does that cable present a 50 Ohm resistance to DC current flow? Can you describe the current flow that exists on such a coax cable if the end is open? When you understand characteristic…
