RF Exposure Regulations
By Milt Hyams, KM6ASI and Bob Salter, AI6EE
Milt Hyams, KM6ASI
Milt is an Amateur Extra living in San Rafael, CA. He became interested in radio as a youngster and received a Restricted Radio Telephone license in 1957 to serve as radio operator on his father’s boat. He tried and failed to get his amateur radio license at that time because of his inability to pass the CW test. Yet, his interest in radio and electronics continued, and upon graduation from USF in the ROTC program he received his commission as a second lieutenant in the US Army Signal Corps. Although he went on to graduate from USF Law School, he elected to stay in the Signal Corps, ultimately commanding two signal companies in Viet Nam. After his tour in Viet Nam, he served over 30 years as an Assistant District Attorney in Marin and San Francisco. He continued to be active in the Army Reserve, retiring as a Colonel in the Signal Corps in 1994. Upon retirement he received the Silver Order of Mercury, the US Army Signal Corps Regiment’s highest award for service to the Signal Corps. In 2016, when he found out that CW was no longer a requirement for an amateur license he immediately became a licensed amateur. Since then he has become active in amateur radio activities in Marin, serving on the Marin Amateur Radio Society Board of Directors. He is currently the Deputy Chief Radio Officer of Marin RACES, is on the Planning Committee for the Marin Radio Communications Volunteers, is the Communications (DST) Coordinator for the Marin Chapter of the American Red Cross and currently serves on the Marin Disaster Council. He is also active in a number of public service and communications training activities in Marin County.

The New MDARC Membership Database
by Jan Kulisek, KM6NFC
The presentation will guide members on how the MDARC Membership Portal can be used to their advantage to check on membership status, among other features. In addition, there will be an explanation of the technology behind the Portal including an attempt to take away fear that personal information may be at risk. Yes, no risks in our lives are zero, but it is possible to mitigate them very close to that. While mitigating risks, web technology can also improve our lives in general, not limited only to the use of the MDARC Membership Portal. The presentation will include some additional ideas how technology can improve our lives in general and not only limited to ham radio operations and how it can help us instead of the other way around. Perhaps we will also touch up a little on the history of radio and how skillful radio operators made the difference in the world, which may be another big topic for a future presentation.
Jan Kulisek, KM6NFC
Born and raised in Prague, Czechoslovakia, which is today the capital of Czech Republic. Grew up during Communism behind the Iron Curtain, which defined curiosity about the world out there especially west of the Czechoslovak border. Almost the only way to get reliable information was back then over the radio waves mostly in short wave bands. These broadcasts were mostly jammed and it took an effort to figure out how and where to get a clear signal of western broadcasts. During those times Jan developed into quite a passion to be an SWL (Short Wave Listener). However, Jan was never too diligent to study electrical engineering and focused more on getting out of the country, which with great luck managed to do and in 1985 arrived in the US. Long story short, after the 20+ years service in the US Army Jan retired and renewed his interest in radio technology mainly because what do you do when a natural disaster strikes and when Internet and cell services are down? Information transmitted over ham radio bands can be a lifesaving commodity and is also fun during peace time when nothing serious is happening. Given the professional experience as a software engineer and scientist Jan also found ways to improve the membership tracking and other MDARC functions via web applications. And that's what Jan's presentation will be about, to take a look behind the scenes how web technologies can improve our lives as ham radio operators to better organize ourselves not only in our club.

EmComm Mutual Aid in a Digital World
by Dan Goldstein KJ6KEU
"EmComm Mutual Aid in a Digital World" builds on lessons learned from recent disasters. "Mutual Aid" answers the question, "If my team can't respond, who will help?" It also clarifies which local teams support the Red Cross, Salvation Army, hospitals, schools, tribal governments, critical infrastructure, served agencies, neighborhoods, and others. In addition, it addresses why the digital component (Internet) needs to be considered, and what resources are necessary (WinLink, AREDN, solar generators, etc.). Finally, it points to standardized training that can help us meet the government's need for resource typing to facilitate mutual aid deployments.

Neighborhood Radio Watch
by Alan Thompson W6WN
Note: This meeting will be held at Pacificon in San Ramon, not at our regular location. See www.pacificon.org for details.
Neighborhood Radio Watch
Since its inception in 2019, the Neighborhood Radio Watch program has helped hundreds of citizens discover the magic and power of radio, not as some novelty from a bygone era but as an indispensable, life-saving tool in the event of emergencies or disasters. There are now over 500 Neighborhood Radio Watch users in El Dorado County alone, and similar Community Radio programs have formed in Sonoma, Butte, Amador, Nevada and Tuolumne counties.
Surprisingly, these programs have not only benefited non-Ham communities but have also benefited sponsoring Clubs. In this presentation we'll cover why these Community Radio programs started, and how they might actually help to ensure the growth of our Clubs and even shape the future of our Amateur Radio Service.

The History of the Log Periodic Dipole Array
by Jim Siemons, W6LK
As far as antennas go, one size doesn’t fill all. Various antennas have different properties for different purposes, and one of the more unique designs is the Log Periodic Dipole Array (LPDA). LPDA antennas are designed to be broadbanded in the frequencies that they cover, be directional, and have some gain. We will discuss their history, evolution, uses and more as we dive into the world of the Log Periodic Dipole Array!
Jim Siemons, W6LK
Jim has had a lifelong interest in science, electronics, and the attempt to understand how the world works. During his formative years he worked as a counselor at Wolfeboro Boy Scout Camp in the Sierra teaching a wide variety of science and environmental based Merit Badges, ultimately becoming Commissioner of Scoutcraft (the Hike Shack!). Those scouting skills still come in handy! Because Jim had a tremendous respect for the women and men of science, he decided not to follow in their path. In spite of that, Jim did earn a Batchelor of Science in the art of recording financial history and pursued a career in direct mail, as a partner in Siemons Mailing Service, Inc. In 2011, Jim decided to follow his passion and purchased Elk Antennas from Ray Gaschk, AG6SI, and Pete Perata, K6SHE. Along with his family, Jim designs and builds Log Periodic Dipole Array antennas (LPDA) and ships them all over the world for use by hams, military, public safety and commercial operators. Over the last year, Jim, his wife Misa, KJ6BUE, son Louis, W7ELX, and daughter Mary have relocated to the wilds of Northwest Wyoming in the community of Clark, Wyoming on 40+ acres. Clark is located at the edge of the Beartooth Mountain Range (part of the Rockies) and is the eastern border of the Shoshone National Forest and Yellowstone National Park. Clark is a community that is about 50 square miles in size and has approximately 300 residents. The Siemons Family is currently building a custom Elk Antennas workshop. In the tradition of this region, Jim is very much into farming - antenna farming!

DMR and D-Star
by Jim Moen, K6JM
The Club is making changes to the W6CX D-STAR repeater. My presentation at tonight’s meeting will cover a bit about digital stuff, what’s called Multi-Mode and what the upcoming changes are all about.
Jim Moen, K6JM
I got my Novice license in 1959, and got on the air with a Collins 75A-2 receiver and WRL Globe Chief Deluxe CW transmitter. I upgraded to General in 1960 and added a screen modulator and VFO for AM phone. I then traded for a Collins 75A-4 and got a Central Electronics 100V for SSB, using a Mosley TA-33 Jr beam and a folded dipole. I was active through the 1960s (using the club station at Brown University), but my career in computers took over and I unfortunately let my license expire.
In mid 2003, I re-tested and got back on the air using my original call K0ZXU as a vanity call. I upgraded in 2006 and got vanity call K6XZ. Finally in 2009, I was able to get this call.
I have done little HF over the last decade, focusing instead of digital voice modes -- DStar is my favorite, but I have 3 multi-mode hotspots and DMR and Fusion radios to go with them. My primary HF station now is an ICOM 7100, but I still like my Kenwood TS-2000, sometimes with an Ameritron ALS-600 amp. I recently put up a new HF sloper antenna, and hope to get active there again.
I did QRP for a while, and am thinking I should get back into it with my FT-817ND and the NUE-PSK Digital Mode. I have taken them to the field using a Pacific Antennas PAC-12 ground mounted vertical.

Walnut Creek CERT Winlink Test System
by John Trinterud, K9ONR
A VHF Winlink System - from design through equipment selection, installation and system test.
In Walnut Creek, our 300+ Community Emergency Response Teams (CERT) team members receive basic training to safely respond to the needs of their neighborhoods following disaster, and to serve as the eyes and ears of the City’s Emergency Operations Center and first responders. Additionally, our CERTs have helped police search for missing minors, run welfare checks during planned power shutdowns, and distribute materials for safety alerts.
Ham radio communications and our 100+ licensed CERT hams play a critical role interconnecting Walnut Creek CERT forces both within their areas and to the CERT Emergency Radio Operator (CERO) radio room serving the Emergency Operations Center in City Hall.
Tonight’s presentation covers a technology and process upgrade on the critical link between our CERT command posts and the EOC, changing from an ineffective paper and people-intensive manual process to electronic messaging using amateur radio. We’ll briefly explain the current manual situation and the many alternatives we evaluated before choosing a somewhat atypical configuration of Winlink Express, VARA FM Wide, RMS Relay and RMS Packet over simplex VHF.
