Personal Computers and Operating Systems - Problems and Solutions

Rami Ersheid and Tasneem (Taz) Rafiq

Every Radio Amateur's ham shack probably has a computer. Computers were used originally for simple roles such as looking up call signs and DX zones from a database or logging contacts or programming the memories of an HT radio. Computers subsequently found a role controlling things such as antenna rotators. In satellite operations, they do tracking calculations continuously and move the antenna to follow the satellite. Today, computers increasingly serve as the front panel displays (graphical user interface or GUI) of many new software-defined radios or SDRs. Most hams will agree that the computer has emerged as a useful tool in the shack.

So what do you do if your computer breaks? In this day of throw-away electronics, should you hang on to that Windows 98 or XP machine a while longer? Can your legacy 32-bit software run on a 64-bit quad-core hyper-threaded machine? If Microsoft really stops supporting Windows XP on April 8, is Windows 8.1 a suitable replacement? Rami Ersheid and Taz Rafiq from QuickFix Computers answer these questions and more. They talk about common hardware problems, software and operating system problems, and IT problems - everything from what hardware breaks most often to how to configure Windows 8 to eliminate its most undesired features or how to get rid of Windows 8 entirely, how to protect against malware, how to recognize infections, and what to do about them. This presentation is a “must see” for the modern Radio Amateur.

The Evolution of Handheld Radios from Walkie Talkie to Modern HT

Ed Fong, WB6IQN

The evolution has been 50 years—from 3-transistor walkie talkies that went a little farther than you can shout to today's full featured dual-band HT's using SDR architecture and costing only $35.

Ed Fong, WB6IQN, will share his 50-year relationship with the “walkie talkie” from the early days of the Allied Knight C100, 100-mW walkie talkie, to the present day inexpensive but yet effective Wouxun and BaoFeng radios.

Along the way, he will discuss the famous Motorola HT220 and its architecture, the Tempo S-1 which was the first hand held synthesized radio, and first mini dual band HT's. The first mini HT's being the Standard 508C, the ICOM IQ7a, and the Yaesu VX2.

For military history buffs, Ed will show a Motorola SCR536 (the radio that landed on Omaha Beach), a PRC77 (the primary backpack radio used in Vietnam), a GE Pocketmate (the radio that was used in the Watergate Break-in) and many more.

Bio:

Ed Fong, WB6IQN, teaches RF Wireless Communications and I/O Design Fundamentals for UC Santa Cruz in Silicon Valley. He taught RF Wireless at UC Berkeley from 1998 to 2011.

Maxwell's Equations in 45 Minutes

Kristen McIntyre, K6WX

Maxwell's Equations are mysterious to many, but they are really a beautiful work of mathematical art that is at the heart of radio. The mathematics seems impenetrable without advanced calculus, however, there is another way to look at it: visually.

Kristen McIntyre, K6WX, takes you inside a Gaussian surface, around a curl, and away from a divergence so that you too can see how these four simultaneous differential equations combine to bring the world of radio to life. You will learn the meaning of Maxwell's Equations in about 45 minutes.

Bio:
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.

Weird Electromagnetic Waves

Steve Stearns, K6OIK

Steve, K6OIK, presents Part 2 of “Novel and Strange Ideas in Antennas and Impedance Matching.” Steve presented Part 1 in February 2013. In Part 2 he describes localized waves. Examples or localized waves are vortex waves, knotted waves, and linked waves. These are electromagnetic waves that follow topologically interesting paths in space. Such waves have properties which some communication engineers hope to exploit for multiple access communication.

Isaac Newton taught that light travels in straight lines. Albert Einstein taught that light consists of discrete particles called photons. Reasoning from Newton and Einstein, we might conclude that photons travel in straight lines. Steve surprises us by showing this conclusion is wrong. The relationship between photons and electromagnetic waves is more complicated than anyone imagined. Steve describes the electromagnetic properties of vortex waves, including properties that are unknown, counter-intuitive, or just plain weird!

Nuclear Reactors for the Complete Ham Shack, Emergency Power, and Clean Green Power

Dr. Alexander Cannara of Cannara Consulting

Suppose someone told you there is a way of generating heat and electrical power on an industrial scale without the fuel emissions, nuclear materials, and waste we now produce, and do it for the whole world for thousands of years, using a cheap, plentiful source. What would you say? Suppose these power sources:

  1. Can't explode because they're unpressurized and produce no flammable materials.
  2. Shut down naturally, without power or people, if something goes wrong.
  3. Are independent of water cooling, so can be built anywhere, using little land.
  4. Get their energy from cheap material abundant on Earth, Moon, and Mars.
  5. Can be made to consume nuclear wastes.
  6. Produce valuable industrial/medical/scientific isotopes now becoming scarce.
  7. Have already been tested and shown to work.
  8. Can be built and operated more cheaply than coal, oil, or gas power.

The technology is the Molten-Salt Reactor (MSR), and the specific variant is Liquid Fluoride-Thorium Reactor (LFTR), developed, designed and operated in the 1960s at the Oak Ridge National Laboratory www.thoriumremix.com/2011. Come and learn what might be the best kept secret for powering your emergency station while combating global warming in the not so distant future.

Bio:
Alex Cannara is in his second career. After a distinguished career in the Silicon Valley chip and software industry, he is now consultant on science policy and technical investment. He lectures widely on energy alternatives and climate-related policies. He has four graduate degrees from Stanford MSEE, Engineer (Plasma Physics and Systems), MS Statistics, and PhD (Mathematical Methods in Educational Research). He is an IEEE Life Member and member of the American Association for the Advancement of Science.
