ATSC 3.0 - HD Television

Joel Wilhite, KD6W

From 2008 to 2009, the United States transitioned from analog TV (NTSC) to digital TV (ATSC). ATSC 3.0 is the newest digital television standard. Why would a ham give a hoot about this new standard? It's television who cares?

Joel Wilhite, KD6W, provides a simple overview of the new standard and why the TV industry is about to have a renaissance of sorts.

Why does it matter to hams? The standard has some very intriguing elements which are not obvious to a common observer. But for the astute observer there are some clever new tools which the ham community could leverage for our purposes.

Bio:
Joel Wilhite, KD6W, works professionally in digital video industry. Joel is the Broadcast Solutions Manager at Harmonic Inc., a local company that makes equipment for digital video compression and transport.

Joel has presented papers at NAB and IEEE Broadcast Technology Society. Joel is also Technical Coordinator and a director of the Palo Alto Amateur Radio Association (PAARA).

Joel has been a force in getting Bay Area radio amateurs to migrate from ATV to DATV. One proud result for Bay Area hams is that Mt. Diablo (W6CX) is the first DATV station in the nation to run 3 channels (4-MHz QPSK) using an advanced state-of-the-art technique called Statistical Time-Division Multiplexing (Stat-Mux). Now that’s a mouthful!

Op-Amps for Fun and Profit!

Kristen McIntyre, K6WX

What is an op-amp? Have you ever wondered? They turn out to be incredibly useful devices that started out as computers! Beyond computing, they have been used for a wide array of fun applications, from simple comparators to doing calculus to exploring meta-stable chaotic systems. Op-amps lean heavily on the notion of feedback, giving us a chance to learn some fundamentals of control system theory. And they're pretty handy around the ham shack too. Let’s take a look at these amazing little devices and see what you could build with them.

Bio:
Kristen McIntyre, K6WX, has been interested in radio since she was 5 years old. She started in Amateur Radio in 1979 getting her ticket while at MIT.

Kristen has worked in many diverse areas from analog circuit design to image processing to starting and running an ISP. She is currently working at Apple in Core OS and spent many years at Sun Microsystems Laboratories, where she was researching robustness and emergent properties of large distributed computer systems.

She is a long time denizen of Silicon Valley and has worked at or consulted for many of the usual suspects. Kristen is an active ham and loves to chase DX on HF with her Elecraft K2, which she built while visiting her mother in Florida. She is an ARRL Technical Coordinator for the East Bay Section, president of the Palo Alto Amateur Radio Association (PAARA), and is active in many local clubs.

Batteries 101

Rachel Kinoshita, KK6DAC

This meeting was one week earlier than usual. It has been scheduled for the 3rd Friday instead of the usual 4th Friday of the month. Be sure to put the correct date on the calendar.

As part of becoming proficient in emergency communications, Rachel, KK6DAC, began researching alternative emergency power methods, including solar, generators, different types of batteries, and what works best for a particular application. In this presentation, Rachel will talk about batteries, the real world testing she has performed with them, and how it applies to ham radio.

Bio:
Rachel Kinoshita, KK6DAC, moved from Oregon to the San Francisco Bay Area in 1989 to work for a start-up email software company and has spent most of her career working in the messaging industry.

She now spends her time fighting spam, malware, and phishing attacks. Rachel considers herself still a newbie to ham radio, having only gotten her license in early 2013. Although like many things, Rachel jumped in with both feet and soon got her general license, an HF rig and starting exploring the world in the low bands.

At the same time, she found herself working with her local Community Emergency Response Team (CERT) to help develop and shape their communications plans and policies. She also found her way to the South County ARES (SCARES) organization where she developed an interest in emergency communications.

Digital Radio Applications for Radio Hobbyists

Adrian Motamedi, K3ADM

Why pay big bucks for new radio gear just so you can listen to some digital signal when there are simple DIY hacks to do the same thing? Adrian, K3ADM, talks about digital radio applications of interest to radio hobbyists and Amateurs: (1) how to make a DMR home hotspot (using ZUM Radio’s ZUMspot board with Raspberry Pi Zero or Pi Zero W); (2) how to decode and listen to public safety transmissions that use P25 Phase II trunking; and (3) how to decode and listen to over-the-air FM broadcasts from HD2 multicast stations.

Bio:
Adrian Motamedi, K3ADM, started his career as a high-speed digital circuit design expert at Siemens, later Infineon Technologies.

In 2007 he joined Juniper Networks, where he worked on system, chip, package and EMI designs.

His last project at Juniper was one of the first backplanes with 10- and 25-Gbps and 3000 links (MX2020, Juniper's flagship product in the Edge market).

His next stops were at Aruba networks and, in 2013, chip startup Xpliant where his team designed and shipped a 3.2-Tbps bandwidth switch chip for “white box” switches at commercial data centers. He worked on the XP 56-Gbps PAM4 chips as Xpliant was acquired first by Cavium and later by Marvell Semiconductors.

He currently works for a stealth automotive startup. Adrian has six patents. He is a member of the IEEE, a board member of a physics non-profit, and holds licenses for Amateur Radio and student pilot. He enjoys hiking and flying small airplanes.

The Mysteries of the Smith Chart’s Radial Loss Scale

Steve Stearns, K6OIK

This meeting was two weeks earlier than usual. It has been scheduled for the 2nd Friday instead of the usual 4th Friday of the month because of Field Day. Be sure to put the correct date on the calendar.

Steve, K6OIK, explores the mysteries of the radial loss scale of the Philip H. Smith’s venerable chart. This scale is almost never used, probably because nobody knows what the scale really means or how it works. In answering these questions, we are led to a more basic question: is the scale even right? Steve presents the equation Smith’s scale is based on, then he shows it disagrees with almost every book on transmission line theory. What was Philip Smith thinking? The story is a maze with intersecting paths, made complicated by layers of approximations.

Ed Fong, WB6IQN

Ed Fong WB6IQN, explains the J-pole and improvements. A J-pole is a popular antenna because it does not require radials and can have up to 1.6 dB more gain than a quarter-wave ground-plane vertical depending on height above ground and ground type. However, there is a way to get even more gain. Ed explains how to convert a J-pole into a collinear by adding elements, all while not affecting the impedance match. The addition of a single extra element can add 3 dB of gain over a standard J-pole, or up to 4.6 dB of gain over a quarter-wave ground-plane vertical! Ed’s method is described in U.S. patent 8,947,313.

Two British Spy Radios of WWII

Hiroki Kato, AH6CY

Hiroki Kato tells the story of the two QRP portable radios that were developed and deployed by the SOE (Special Operations Executive), a clandestine paramilitary organization to engage in sabotage and organizing local resistance fighters in the Nazis-occupied Europe. Named the “B2 /Type 3 Mark II” and the "Mark VII” (nicknamed the “Paraset”), they were used by the British trained agents as well as local fighters to communicate with London. Hiroki brings and shows the original radios and a working replica of the Paraset. This talk is based on Hiroki’s article that appeared in QST, April 2016.


B2 / Type 3 Mark II

Mark VII / Paraset

The program originally scheduled for this date is being rescheduled for 2020.

Bio:
Hiroki Kato, AH6CY, was born in Hiroshima, and was first licensed as JA4AAO when he was in high school.

After college, he came to the US to pursue graduate studies. Dr. Kato taught political science and linguistics at several universities, including the University of Hawaii, Harvard, and Northwestern.

He got his current call sign when he lived in Honolulu.

He later worked for early Silicon Valley startups, retiring in 2000. He enjoys QRP portable and QRO remote operations, having been on the air from many states and countries.

When at home in California, he collects and restores boat anchor radios, focusing on World War II-era radios.

The Art and Science of QRP

Doug Hendricks, KI6DS

[Meeting scheduled in Room 32 this month]

Doug Hendricks, KI6DS, talks about QRP. For those unfamiliar with the term, QRP is a lot like an Amateur Radio version of the Spy Radios that we learned about last month. Small radios that run on batteries which enable you to access the HF bands and engage in long distance QSOs. Whether you are a ham or a secret spy, be sure to come and learn about this fun aspect of the hobby!

Bio:
Doug Hendricks, KI6DS was the founder and owner of Hendricks QRP Kits, http://www.qrpkits.com. He sold the company in 2015 to Pacific Antenna, maker of the PAC-12 portable vertical, but Doug still finds time to consult on new QRP kit projects.

Doug has long been an advocate of bringing affordable, relatively easy-to-build kits to the QRP community. He has collaborated with Steve Weber and others in recent years to market such radios as the PFR-3, the Ft. Tuthill transceivers, and many other receivers, tuners, and useful accessories as well as pieces of quality, yet inexpensive test gear.
