To PL Or Not PL, That Is The Question
by Eric Dausman, KD7DNM


Ham radio operators use the Continuous Tone Coded Squelch System (CTCSS) almost every day, but do not fully understand it. You may have heard it referred to as  “PL”, “tone”,  or something else; this is a legacy technology which still functions well.  


This presentation will discuss CTCSS history and explain some basic technical specifications and use cases most ham radio operators may not be familiar with.  It will also explain common misunderstandings of what the technology provides and how it is used in other radio services.


Eric Dausman, KD7DNM

Eric Dausman recently retired from a 45 year career in Broadcast Radio and Television.  During that time, he worked for local and network broadcast centers as well as overseeing Sutro Tower, one of the largest broadcast infrastructure facilities in the United States.  Eric has a broad understanding of RF technology including broadcast radio, television, and land mobile radio.  


Eric moved to Moraga in 2009 and became a member of the Lamorinda Area Radio Interest Group (LARIG). He was largely responsible for the design and implementation of a LARIG tri-city amateur band linked repeater system and complementary GMRS repeater system to supplement and strengthen the cities’ emergency communications systems. He was an active member of Support 241, the Moraga Orinda Fire District volunteer communicators.


Eric currently lives in Lake Oswego, Oregon and volunteers his time to the Lake Oswego Fire Department, Lake Oswego ARES, and Clackamas County ARES.  Eric is married and has two grown sons and six grandchildren.    


Eric is a member of SMPTE, SBE, and holds an Extra Class Amateur Radio license with the call sign of KD7DNM.

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.
