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.

AMSAT-NA OSCAR Number Administrator

W6TRW General Meeting

Dec. 12, 2017, Tuesday

Roundtable Pizza, 4330 Redondo Beach Blvd, Torrance 

Guest Speaker:  Bill Shanney, W6QR

“QRP – Low Power Operation”

Bill Shanney

QRP — “Shall I decrease power?” “Decrease power.”

QRP has come to mean 5 W or less output for CW, or 10 W PEP output or less for SSB.

Most amateur organizations and contests embrace these as the official QRP limits. QRP exemplifies the spirit of the Rules — specifically 97.67(b), which states that “… amateur stations shall use the minimum amount of transmitter power necessary to carry out the desired communications.”

Many of the same amateur activities are alive and well within the QRP community. These activities include constructing home-brew equipment, operating QRP stations, experimenting, DX chasing, and contesting.

 “My first call was WV2RDG in NJ. I became WA2RDG when I got my general in 1961. I operate 99.5% CW on 160-6M.

After a long period of inactivity (career and family) I upgraded to extra class in 1988 and became very active. That is also the year that I joined the TRW ARC.

I have a BSEE from NJ Institute of Technology and worked for 45 years in RF and microwave design. I retired from NG/TRW in 2007 after 31 years with the company.”

 The Monthly W6TRW General Meeting is a great place to meet other club members and to ask and answer questions about your radios, local repeaters, and all other radio-related topics.

Wednesday Noon W6TRW Radio Nets

For many years, we have held a weekly Wednesday noon radio net on our 145.320 MHz and 447.000 MHz repeaters, for W6TRW Emergency Communications Team members to check in.  We are now opening this net to all W6TRW members, to get more club participation, and  generally increase the number of members who are aware of emergency communications resources.

Check-ins to this net reply with their general location, and their radio communication capabilities at the time.

We’re also looking for more control operators for this net.  Control ops rotate on a schedule, typically only coming around every 4 weeks or more.  There is a brief script to read, and a simple structure to the net, that you can hear by tuning in on any Wednesday noon.  The whole net only takes about 10-15 minutes.  Please contact Greg, KE6YEX if you want to join the control op rotation.

HF Family Net:

Also at noon on Wednesday is a long-running company net on 14.270 MHz.  Employees / retirees are welcome to check in and represent the West Coast!

If you want to volunteer for (or find out about) various radio-related events or activities taken on by members of the W6TRW club, please send us a message and we will get you in touch with the right members.

……….Whiskey…..…. 6 ……….Tango……….Romeo……….. Whiskey………..

w6edsScott, became a Ham Radio operator in 1991. He worked with L.A. County RACES/DCS transmitting video of significant events back to law enforcement command posts. “I was usually in a Sheriff’s helicopter, with no door, hanging outside with a video camera connected to a packet radio transmitter.”

“My rig is a Yaesu FT-2000D with a Radio Wavx G5RV Lite Antenna inverted and just   slightly off the roof line of my house peaking about 6’ at its highest. Not the most ideal, but the best I can do, since there are HOA restrictions.”
