The files that I sent are for setting up a Kenwood TH-D72A with RT Systems software for satellites.

Hi Brad,
Not sure if you sent me the file, but try again. It may only for a PC system,  but I think I may have and old PC that might be able to open it.

PC control of HT or mobile rig?

Troy - K4JDA
 

Is there any way to connect something like SatPC32 to the Kenwood TH-D74 to automatically adjust frequencies for Doppler shift?

If not, are there any HTs or Mobiles that can do this?  Or do you have to lug a base station around to get this capability?

ARISS Contact Opportunity - Call for Proposals

Message to US Educators 

Amateur Radio on the International Space Station 

Contact Opportunity 

 

Call for Proposals 

Upcoming Proposal Window is February 1, 2020 to March 31, 2020

 

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS is happy to announce a proposal window which will open February 1, 2020  for contacts that would be held between January 2021 and June 2021. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. 

 

The proposal window for contacts between January 2021. and June 2021 will open on February 1, 2020 and close on March 31. 2020.  Proposal information and documents can be found at www.ariss.org. Two ARISS Introductory Webinar sessions will be held on two different date and times. The first is at January 23 at 2100 ET and the second is at Jan 27 at 1800 ET. The same material will be covered during both sessions, so choose the session that best fits your schedule. The Eventbrite link to sign up is https://ariss-proposal-webinar-spring-2020.eventbrite.com .

 

 

The Opportunity 

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. 

 

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. 

 

Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations' volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

About ARISS:

 

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS).  In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

CAS-6 Activation Delayed

Clint Bradford
 

CAMSAT Says CAS-6 Activation for Amateur Use has been Delayed publicado en: / published in: https://qrznow.com/camsat-says-cas-6-activation-for-amateur-use-has-been-delayed/ 
 
Chinese Amateur Satellite Group (CAMSAT) CEO Alan Kung, BA1DU, tells ARRL that some problems with the precise attitude determination of the newly launched CAS-6 amateur radio satellite have delayed deployment of the antennas. The satellite was to have been put into service within 3 days.
 
“If the V/UHF antennas are deployed now, additional torque may affect determination of the satellite attitude,” Kung said. “Engineers need to modify and upload the software, which will take some time.” He said that taking into consideration the upcoming long Chinese New Year holiday, the test work is planned to be completed sometime in late February or early March. At that time, VHF/UHF antennas will be deployed, and the amateur radio payload will be available for use.
 
Kung points out that the satellite’s CW beacon has been turned on, although the antenna has not yet been deployed. “If you have a ‘big ear,’ you may be able to receive weak signal leaked from an undeployed antenna on 145.910 MHz,” he said. “A polyimide cover on the antenna chassis can help to leak some RF signal.”
 
CAS-6 launched successfully on December 20, piggybacked on a TIANQIN-1 technology test satellite. The microsatellite will be known as CAS-6/TIANQIN-1, and the call sign is BJ1SO. The primary launch payload was the China-Brazil Earth Resources Satellite, CBERS-4A.
 
CAS-6 is in a sun-synchronous orbit with an apogee of 390 miles. It carries a U/V linear transponder, with a downlink of 145.925, 20 kHz passband (inverted) and an uplink of 435.28 MHz. The CW telemetry beacon is on 145.910 MHz, while 4k9 baud GMSK telemetry will be transmitted on 145.890 MHz.
 
CAMSAT has provided CAS-6 Satellite Digital Telemetry Description and CW Telemetry Beacon Encoding Format documents. — Thanks to Alan Kung, BA1DU
