Title: What’s all this Antenna Tuner Stuff, Anyhow?
For the July monthly meeting of the Cascades Amateur Radio Society, Wes Cardone (N8QM) will pick up where he left off in the June meeting with cable termination reflections and cable length. But this time we will take an analytical look at feedline analytics. We will look with critical analyses at the terminations where reflections will be or not be seen.

Title: What’s all this Impedance Matching Stuff About, Anyhow?
For the June monthly meeting of the Cascades Amateur Radio Society, our presentation was given by Wes Cardone, N8QM, on impedance matching. But this was from a perspective that most amateurs have likely not considered.
Wes asked the question, “So, what’s all this impedance matching stuff about, anyhow?” Why is it that in amateur radio that we pay so much attention to all this impedance matching? Is it really important in all cases and why or why not is it important? None of us worry too much about impedance matching for our living room incandescent lamp fixture. Yet it has all the elements of interest with an electrical signal source, distribution cable, and a load. What makes amateur radio any different, anyhow?

Jeff handles all of the maintenance on the Chelsea and Manchester repeaters and what a masterful job he has done, and continues to do, on them! This is your “go-to man” for all of your amateur radio questions.
Jeff gave a presentation which he gave earlier this year to the Chelsea Amateur Radio Club on WinLink. I attended this presentation and thought it was truly down-to-earth and well laid out.
A video recording of this presentation has been edited and uploaded for viewing.
CARS Meeting of April 20th, 2021

What is the difference between a crystal radio and a radio crystal? What role did rock crystals play in winning WWII? What is the relation between a rock and a crystal, an atom and an ion, and why should I–as a ham radio operator–give a hoot?
These and other interesting questions were answered during the presentation titled “Radio Rocks! A geologist looks under the hood.” Please keep visiting this page to see a video of this presentation when it becomes available.
Here’s How to Log Into Our Meetings
If new to video conferencing we recommend logging in at maybe 6:30pm to give yourself some margin. While actual meeting content begins promptly at 7PM EST, you may want to jabber-jaw with other amateurs between 6:30 and 7:00PM while waiting for the meeting to begin.
You may video conference either using an installed Zoom application or participate from a browser. The easiest way is to use the “Online Club Meetings” button on the club home page. Clicking on the home page “Online Club Meetings” button takes you directly to the meeting. If the meeting has not yet started, then you will already be there when it does.

Speaker: Steve Waterman, K4CJX

More than ever, the U.S. Amateur Radio spectrum is under observation for use by commercial communications giants. We have just experienced a loss in the GHz range and the loss is likely is not over yet. While the ARRL is working to protect our Amateur frequencies, at the same time there are supplemental avenues to successfully maintain the amateur spectrum. Recognizing the issues the Amateur Radio operator faces and the need for our services, the Department of Homeland Security’s Cybersecurity & Infrastructure Security Agency (CISA) SHAred RESources (SHARES) program advocates the use of Amateur Radio volunteer resources for the installation, operation and maintenance of its agency member stations.
For our March 16th meeting Steve Waterman provided information about the CISA SHARES program and how amateurs can become involved. This presentation and discussion was a follow-up to Max Schneider’s January 19th CARS presentation about the CISA Emergency Communications Division (ECD) AuxComm solution for Amateur Radio EmComm. Winlink radio email, which has been adopted by the Department of Homeland Security for its own use is an important tool in the processes and was part of Steve’s presentation.
Here are the notes from Steve’s presentation: Why SHARES by Steve Watermann

For the January 19th meeting our speaker was Max Schneider presenting on Michigan’s AuxComm. It has been announced that many of Michigan’s RACES organizations are being decommissioned in favor of AuxComm. This presentation was therefore of intense interest to many of our members and amateur radio operators of surrounding counties. Attendance was nearly 30.
Here are the PDF notes Max gave us from the presentation:
