Adrian Motamedi, K3ADM, graduated in the field of microwaves and high-frequency technology. After university, he started his professional career as a high-speed digital circuit design engineer at Siemens, later Infineon Technologies.

In 2007 he joined Juniper Networks, where he worked on system, chip, package and EMI designs. For Juniper's MX2020 flagship product for the Edge market, he developed the first backplane having 3000 links at 10- and 25-Gbps.

At Aruba networks and subsequent chip startup, his team developed a 3.2-Tbps switch chip for switches at commercial data centers. The startup was acquired Cavium Inc., and then by Marvell Semiconductors.

He then joined an automotive/clean energy company and worked on EV infrastructure in the US and abroad.

Adrian currently works for an AI startup. He has six patents in the field of high-speed design and simulation. He speaks at JEDEC & Design-Con conferences. He is a member of the IEEE and is a volunteer on the boards of directors of FARS and a physics non-profit. Adrian is an avid hobbyist who holds licenses for Amateur Radio, boating, and as a student Pilot. He enjoys hiking, flying small airplanes, following the stock market and financial statistical analytics and prediction algorithms and software.

Kristen McIntyre, K6WX, has been interested in radio since she was five years old. As a youth, she built many radio kits including her favorite: a one-tube radio kit.

Kristen started in Amateur Radio by getting her Technician’s license in the late 1970s while an undergraduate student at MIT. She built a 2-meter repeater with an autopatch to use while on campus at MIT. Kristen now holds an Amateur Extra class license and also is licensed in Japan as JI1IZZ. She is active on 2 meters, 1.2 GHz, and HF. She built an Elecraft K2 while on vacation. Kristen likes to work HF mobile using the K2 and a hamstick. She also operates from her apartment using an Icom IC-7600 driving an Ameritron AL-811H power amplifier into a homebrew helical vertical dipole. She loves to chase DX using mostly CW, and works contests from time to time.

Kristen’s professional career has been diverse. In the early 1980s, she designed high-power linear amplifiers. She spent five years in Japan, architecting and designing precision analog test systems while learning the Japanese language and culture. Kristen returned to the U.S. and has worked at or consulted for Silicon Valley tech firms. At Adobe Systems, she architected PostScript Level 2 and its RTOS underpinnings as well as AppleTalk networking for PostScript printers. In the early 1990's, she became a consultant and later founded an Internet service provider and a network consulting firm. At Sun Microsystems Laboratories, she did research on the robustness and emergent properties of large distributed computer systems. She is currently a senior software engineer at Apple Computer, working on OS X and iOS.

Kristen holds a degree from the Massachusetts Institute of Technology. She was officer and president of the Palo Alto Amateur Radio Association (PAARA). She was ARRL Technical Coordinator for the East Bay Section, and in 2018 became ARRL Pacific Division Vice Director. Kristen is currently serving as ARRL Pacific Division Director and ARRL First Vice President.

Keith Snyder, KI6BDR, is a master power user of the FEKO numerical electromagnetics code for antenna modeling and analysis. He started using FEKO 23 years ago as user no. 8 in the U.S. and no. 1 at Northrop Grumman.

Keith is an expert at reverse engineering antennas using photos and AutoCAD to import complex models into FEKO.

Keith studied antennas under at The Ohio State University. He had the great fortune of having Professor John Kraus as his electromagnetics instructor. Keith’s aunt was Kraus’s secretary! Keith graduated from Ohio State in 1980 and picked up a Telecommunications Certificate from U.C. Berkeley.

Keith has considerable antenna design experience having worked on a wide variety of antenna applications including: AM antenna matching at Harris Broadcast in Quincy, Illinois; reflector antennas using the NECREF code at GTE in Needham, Massachusetts; patch antenna arrays at Ball Aerospace in Boulder, Colorado; radar antenna design at Aydin Radar in San Jose; broadband antennas at GTE in Mountain View; shaped reflector antennas at Space Systems Loral; Keith worked on modelling antennas on multiple aircraft for Northrop Grumman first in Sacramento, then San Jose and now in San Diego.

His current position is with Northrop Grumman Space Systems Division’s Dulles, Virginia, location. He is working on the Gateway project which is a space station that will circle the moon as part of Project Artemis.

In addition, he is working on a project to improve antenna links in the battlefield including drones and drone mitigation.

Finally, Keith has been preparing for retirement and has picked up hobbies. Mainly photography (SpaceX launches with a 500mm lens) and flying his DJI Mini 2 drone (in Hawaii and beyond).
