FT8; Fundamentals and History
by Ed Muns, W0YK

The talk will start with some LotW and ClubLog statistics on submissions by mode (CW, SSB, RTTY, JT and FT4/8), then put FT4/8 in context with amateur digital history.  The bulk of the presentation will discuss various aspects of the FT4/8 modes.  Questions are welcome.

Ed Muns, W0YK
Ed entered CW and SSB DX contests initially in the early 1970s as a way to work new band/mode-countries for DXCC.  His interest rapidly evolved from DXing to contesting with his early learning at the K0RF multi-multi.  Today, CW and RTTY contesting dominate Ed's operating time.  His local contest club, the Northern California Contest Club (NCCC), mounted an effort for the club competition gavel first offered in the 2004 ARRL RTTY Round-Up where Ed reluctantly (kicking and screaming) learned how to setup RTTY and ultimately won the Pacific Division SOHP plaque.  He ironically enjoyed that induction into RTTY so much that he now includes all the major RTTY contests in his contesting schedule.  With his P49X call sign, Ed holds the world SOHP record in ARRL RTTY Round-Up, having broken the record eight times, and the world SOHP record in CQ WPX RTTY, having broken that record seven times and set a world SOHP record in the 2010 CQ WW RTTY.  Ed is the contest manager for the NCJ NA RTTY Sprint and the contest director for the two CQ RTTY contests, CQ WW RTTY and CQ WPX RTTY.  He and Don, AA5AU, sponsor the Ten-Meter RTTY Contest which they initiated in December 2011 with nearly 700 logs submitted.  In 2018, it became the FT8 Roundup with over 1200 logs using ARRL RTTY Roundup rules.  He was inducted into the CQ Contest Hall of Fame in May 2014.  This is his twelfth year at CTU delivering the two Digital Contesting presentations and Q&A.

ARKnet - Wireless Emergency Intranet

by Marcel Stieber, AI6MS

ARKnet is the first step toward building a Wireless Emergency Intranet for the City of Cupertino that will support our emergency responders with a high-speed data network. This multi-site network uses a 5.8 GHz ISM backbone and includes off-grid solar sites throughout the city. This forum will provide an overview of the system including design considerations, initial deployment of the primary sector and client sites, and operational analysis of the system functionality.
* A copy of Marcel's presentation slide deck is available here.
* A multi-part video of Marcel's presentation at Pacificon 2016 on this topic is on YouTube here.
* Marcel's QRZ page, with a more detailed bio and links to other presentations is here.

Marcel Stieber, AI6MS
I am an Electrical Engineering alumnus of California Polytechnic State University in San Luis Obispo. I am currently employed as a Hardware Systems Integration Lead at Amazon Lab126 in Sunnyvale, CA and also serve on the Cal Poly Electrical Engineering Industry Advisory Board. I was former President and am current Industry Advisor to the Cal Poly Amateur Radio Club (www.W6BHZ.org). I am regularly volunteering to help at local repeater workdays as an RF technician and tower climber. I also enjoy helping with community events and providing communications for bike rides and triathlons. I was licensed on Cinco de Mayo in 2008 and received my Extra License in the Summer of 2010. I am also an ARRL Life Member and have used my VE credentials to help license over 673 hams since 2009!

I especially enjoy portable stations and events, APRS, ARDF, and out of the ordinary operating locations (like on a jetski or bicycle!). In 2013, I was appointed to the ARRL Committee on Youth by President Kay Craigie N3KN. I am the Technical Deployment Manager for the Cupertino ARES ARKnet Project which is building up a high-speed wireless intranet for the emergency responders in Cupertino.

I operated portable in Ghana, West Africa as 9G5MS from January-May 2013. I also operated during the ARRL School Club Roundup in February as the first school to participate from Africa.

Go Kits
: Radios in a Box
by Art Mayoff, AA6AM

At the invitation of MDARC, I will be bringing three different styles of GoKits that I designed and built for the Benicia ARC.  We will be talking about the design criteria behind each, and their contents and construction. The presentation will be non-technical in nature primarily aimed at those who have been toying with building their own GoKit. Hopefully I'll provide ideas to help you get started. We’ll even provide a rather comprehensive parts list.

Art Mayoff, AA6AM
I’ve been licensed continuously since 1961 and hold both US and Canadian licenses (AA6AM and VE2AQV). I’m a former board member of MDARC and a past president. I was MDARC’s auctioneer for 25 years. I taught MDARC’s Ham Radio evening classes when they were conducted at SunValley Mall, College Park and Pleasant Hill High Schools in the 60’s and 70’s.

Prior to retiring in 1999, I was President and CEO Contra Costa’s only Ham Radio store (The Base Station) in downtown Concord for almost 25 years. Who remembers the phone number? (It was 685-73 88.)

I’m an ARRL certified instructor and a CERT instructor, and an accredited Volunteer examiner for both ARRL and W5YI. Also a member of Solano County Sheriff’s Auxiliary Communications Service (ACS) team and a 16 year volunteer with the Benicia Police Dept.

O Solar Mio!

by Roger Hooten, W6UZ

Solar panel RFI mitigation is not a science. There are many opinions on best type, even if there is interference.  This presentation will focus on one type of system for a local 30 panel roof install completed a year ago.  The install followed a QST Solar article approach closely, but with an unexpected outcome. Types of solar systems will be introduced briefly.  RFI observations, tips and tricks learned, along with the costs to mitigate RFI for my HF Ham radio shack will be revealed!

Roger Hooten, W6UZ
I picked up my Novice while in High school, with the help of a Florida Elmer, whom I am still in touch with. I ended up not doing much with it and the Heathkit and old Hammarlund, as military family moves kept me uprooted regularly. I was still intrigued with radio and maintained the license and upgraded over the years to Advanced.  When I finally settled in California I went through the MDARC full set of classes to refresh, and snagged my Extra 2 years ago. I participate in various public service events but DX is my passion. I keep active, despite the solar cycle, with FT8 when I get depressed.  My house sits in a bowl so I continually complain that I can't get out.  Consequently I have grown a  very respectable Rube Goldberg ugly wire antenna farm.  It seems to work as I am within a dozen of DXCC now after 2 years. I don't show my face to my neighbors.

Parachute Mobile - Past-Present-Future
by Rob Fenn, KC6TYD

So why do they jump out of a perfectly good airplane? Come and join us for an exciting and informative presentation where Rob will take you through ten years of Parachute Mobile.  Using skydiving as a platform, discover the many unique projects that the members of Parachute Mobile have incorporated into each mission.

Rob Fenn, KC6TYD
Rob has been in the EMS field since the mid 90's. He is currently working as a paramedic with AMR in Santa Clara County.  When Parachute Mobile began Rob was recruited as the Safety Officer. When the Team Coordinator position opened up Rob grabbed it and has been handling all the coordinating, scheduling, and promoting ever since. Rob was not a skydiver when he started with the team.  Being around and involved in the sport got him interested and in 2011 Rob took the course and soon thereafter was making his own QSO jumps.
