Guest Speaker from Silicon Valley:  Edison Fong, WB6IQN

“A Tri-Band Antenna for 2 meters, 220 MHz,

& 70 cm Antenna Without Radials”

WB6IQN will present his new patent on a Tri Band base antenna (TBJ-1),
featured in QST March 2017. The antenna operates on 2mt/ 1.25mt/ 70cm. It uses no radials
and is only 6ft tall.

Ed worked on this concept for several years and first presented this antenna design at Pacificon 2015.
He will give a historical perspective of how this antenna was developed and also explain how this antenna works.
Since its introduction, its popularity has exploded. Sales have not only been to the ham community but also to military, government and commercial applications.

Guest Speaker:  Jeff Reed, KK6TXO

“Jeff Reed shares his SOTA experience”

Summits on the Air (SOTA) is an ongoing ham radio contest, that encourages portable QRP operations in the mountain terrain. Each summit earns the ‘activators’ and the ‘chasers,’ a score which is related to the height of the summit. ‘Short Wave listeners’ confirm a QSO. Certificates are available for various scores, leading to the prestigious Mountain Goat and the Shack Sloth trophies. SOTA was launched March 2, 2002 and there are over 118 associations around the world.


W6TRW Club Commissioner, Jeff Reed treks up mountain tops to make that radio contact.

NBC News Report Says Hams “Could Save Our Lives” in a Disaster

 

A team from NBC News’ digital news unit Left Field was in Hawaii to visit with some radio amateurs to produce a report when the false nuclear missile alert happened on January 13.

Left Field’s report points out how much we rely on cell phones and 21st-century technology…and what we would do if these suddenly were no longer available. Amateur Radio operators “are standing at the ready and may save us all,” NBC Left Field said in its report. The report, with Left Field’s Jacob Soboroff, runs 7:22.

“Ham radio is one of the ways you’d be able to hear what’s happening,” when conventional telecommunications systems fail, Soboroff told his viewers.

NBC News says its Left Field unit “is a new internationally minded video troupe that makes short, creative documentaries and features specially designed for social media and set-top boxes.”

“High-Altitude Weather Balloon Launch”

pic1

It began with ham radio…. In 2016, Mrs. Michael decided she wanted to launch a high altitude weather balloon with her students. A science mentor of hers told her she had to obtain a ham radio operator license. She joined a group of mostly g randpa ham radio operators in Torrance and got her own license; the group, who dubbed themselves the ‘balloonatics’, then helped with the class project, to launch their own balloon.

In April, she received clearance from the F.A.A. to have her (32 kindergarten-5th grade) students launch a helium filled High-Altitude weather Balloon (HAB) from the Goodyear Blimp Airfield in Carson, reaching 98,405 feet (18.6 miles), using APRS to track the payload of GoPro cameras a one 360 Degree Pix Pro camera. This past March, she led another HAB, this one going 110,288 feet (20.9 miles) at its peak height.

Meet KM6BWB

She is a K-5 science teacher at Meadows Elementary in Manhattan Beach. Joanne is a Space Camp for Educators and Advanced Space Camp for Educators graduate, and is currently an International Ambassador for Space Camp.

On September 8, 2017, she coordinated and led an ARISS (Amateur Radio on the International Space Station) contact with ESA astronaut Paolo Nespoli, IZØJPA.

The 2017-18 Teacher of the Year for Meadows Elementary, Joanne’s future aspirations are to get her district more attuned in Ham radio (with at least one operator at each site), and to introduce Fox Hunts to her students.

One More Note: The high altitude launches were funded by MBEF’s “Teachers Driving Innovation” grants, which supplements state funding for programs that inspire learning, enrich teaching, and promote innovation and academic excellence in the public schools of Manhattan Beach. W6TRW club member, Elizabeth Kunkee, KS4IS, is a MEBF volunteer.

Ham Radio CubeSat Launch Success

cnusail-1-credit-kari-blog

CubeSats carrying amateur radio payloads were among the 31 satellites successfully launched on January 12 at 0359 UT on the ISRO PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India.

Two of the CubeSats, Fox-1D and PicSat, carry amateur radio FM transponders, but neither is yet available for general amateur use. The PicSat FM transponder is unusual in that instead of a CTCSS tone it requires a 1750 Hz tone burst to activate. The 1750 Hz tone burst used to be popular on IARU Region 1 FM repeaters in the 1980s and 90s before the widespread use of CTCSS.

CNUSail-1, built by students at the Chungnam National University in Korea, carries a deployable sail. The students have requested the help of radio amateurs in receiving the 437.100 MHz 9600 bps BPSK beacon, further information is available at https://sites.google.com/view/cnuusg

JE9PEL lists these frequencies for the satellites carrying amateur radio payloads:
Fox-1D (AO-92) 145.880 down 435.350/1267.350 up FM CTCSS 67.0Hz/200bps DUV
PicSat   435.525 1200bps BPSK
CNUSail-1     437.100 9600bps BPSK
Canyval-X 1/2  437.200 9600bps MSK
KAUSAT-5 437.465/2413.000 9600bps FSK,115k2 MSK
STEP-1 437.485 9600bps FSK

Shankar A65CR/VU2SWG reported coping the Fox-1D satellite voice beacon on the morning pass at 30 deg elevation in Dubai using a TH-F7 with standard rubber duck. YL voice with satellite identifier. Very short burst with fluctuating carrier.

Madhu A65DE also copied Fox-1D from Fujairah, North of Dubai.

 

AMSAT North America has issued a statement formally designating Fox-1D as AO-92:

Fox-1D, a 1U CubeSat, is the third of AMSAT’s five Fox-1 CubeSats to reach orbit, being preceded by AO-85 (Fox-1A) and AO-91 (RadFxSat / Fox-1B). Fox-1D carries the Fox-1 U/v FM transponder, with an uplink of 435.350 MHz (67.0 Hz CTCSS) and a downlink of 145.880 MHz. In addition, Fox-1D carries several university experiments, including a MEMS gyro from Pennsylvania State University – Erie, a camera from Virginia Tech, and the University of Iowa’s HERCI (High Energy Radiation CubeSat Instrument) radiation mapping experiment. Fox-1D also carries the AMSAT L-Band Downshifter experiment which enables the FM transponder to be switched to utilize an uplink of 1267.350 MHz (67.0 Hz CTCSS).

Fox-1D was sent aloft as a secondary payload on the Indian Space Research Organisation (ISRO)’s PSLV-XL rocket as part of the PSLV-C40 mission. Fox-1D was one of thirty-one satellites successfully deployed on this launch.

Since Fox-1D has met all of the qualifications necessary to receive an OSCAR number, I, by the authority vested in me by the AMSAT President, do hereby confer on this satellite the designation AMSAT-OSCAR 92 or AO-92. I join amateur radio operators in the U.S. and around the world in wishing AO-92 a long and successful life in both its amateur and scientific missions.

I, along with the rest of the amateur community, congratulate all of the volunteers who worked so diligently to construct, test and prepare for launch the newest amateur radio satellite.

William A. (Bill) Tynan, W3XO
AMSAT-NA OSCAR Number Administrator
