Last year, Roger Steyaert K7RXV made an interesting presentation to the club on the topic of network analyzers, one of which was a program called EZNEC. He just alerted us to an important announcement from Roy Lewallen, W7EL, about his retirement and plans to release EZNEC to the public domain. If you have ever used EZNEC or thought about using it, you’ll want to check out the details HERE:

Basic Antenna Principles Using Antenna Modeling
This program by Mike Mladejovsky WA7ARK was recommended to us by club member Roger Steyaert K7RXV. The presenter is a knowledgeable retired professor. This video starts in the middle of the recording but at the beginning of his presentation.
Program 5/6/2021 on RF Exposure Rules
Our VP Rich K3VAT wants to ensure that club members are informed about these rulings. CLICK HERE for our previous post on the subject and links to the rulings and deadlines.
The first education program on this topic was at our club meeting on Thursday, May 6, 2021 at 7:30pm: a 20-minute YouTube video by Dave Casler, KE0OG.
In case you missed the program, you can view it here:
Smith Chart Basics from Keynight Labs
This video explores Smith Chart basics, and uses that information to learn about the RF performance of a paperclip.
Would this make a good antenna, at what frequencies does it resonate?
A Smith chart makes this really easy to see.
FCC’s 2019 R&O on RF Exposure Standards
UPDATE from Rich K3VAT:
In the last SVARC Zoom Meeting (4/15/2021) during the VP Report, I mentioned that: “The FCC has announced that rule changes detailed in a lengthy 2019 Report and Order governing RF exposure standards go into effect on May 3, 2021. The new rules do not change existing RF exposure (RFE) limits but do require that stations in all services, including amateur radio, be evaluated against existing limits, unless they are exempted. For stations already in place, that evaluation must be completed by May 3, 2023.
Additionally, I mentioned that a large part of future SVARC Program Presentations would be centered around this very important topic because it affects every amateur using any kind of radio transmitter whatsoever. I am currently watching the ARRL.ORG website for updates that will be passed along. For the first presentation on May 6, 2021, I’ve chosen a 20-minute YouTube by Dave Casler, KE0OG.
