ARISS thanks everyone in advance for their assistance. Feel free to send your reports to aj9n(a)amsat.org or aj9n(a)aol.com. **************************************************************************** *** Message to US Educators (***) Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Proposal Window February 15 – April 15, 2017 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 anticipates that the contact would be held between January 1, 2018 and June 30, 2018. 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 deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. 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, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact.

BY70-1 decay estimate
by Nico Janssen 18 Feb '17

18 Feb '17

All, If the current trend continues, BY70-1 may be expected to decay and burn up in the atmosphere by mid-February. The apogee of the satellite has decreased from initially 520 km to now 426 km and the perigee has decreased from initially 216 km to now 208 km. 73, Nico PA0DLO

best sat radio
by Jim White 18 Feb '17

18 Feb '17

I'm working with a university that is launching a UHF half duplex satellite in a few months and is putting a ground station at U Alaska Fairbanks. We are planning on a TS2000 for the radio. I've not seen any new ones pop up lately but thought I'd ask if that one is still a good choice. Seems considerable overkill for a single UHF freq with 9k6 GMSK modulation.

Have the box and everything that came with it (except maybe the warranty card). I do not have a speaker mic like Jeff had. Cable for programming included. Software can be downloaded from Kenwood's website. $300 including shipping in Continental U.S. only. Payment via PayPal. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2018 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

Re: [amsat-bb] BY70-1 re-entry
by Scott 17 Feb '17

Sorry Greg & everyone; I was not knowledgeable enough to put a number on it – after the last pass I trust that everyone has been able to make their own adjustments. For me it was in the area of a few minutes, but it was moving so fast compared to other sats that I couldn’t get much of a feel for how far off from the track I was expecting. Just not enough experience on this end. -------------------------------------------------------------------------------- From: Greg D Sent: Friday, February 17, 2017 1:01 PM To: Scott ; amsat-bb(a)amsat.org Subject: Re: [amsat-bb] BY70-1 re-entry Also, the predicted AOS from the latest Celestrak keps agrees within 6 seconds to using Nico's 19:00z set. I'm thinking it's going to be about on time, no? Greg KO6TH Greg D wrote: How "way" ahead? Minutes? Tens? My next pass is reported to be at 19:36z (11:36am local PST).

Go get LMR-400UF and it is much more flexible. I use it for jumpers, and many other do as well. Nick, KE8AKW

BY70-1

Satpc32 is now showing the satellite as again being white !! Is there a reason why it would show red ?? I believe this is the first time I have noticed the change during a pass. Thank You JACK-KC7MG

BY70-1

At 2249 utc time while tracking BY70-1 on Satpc32, the cross representing the satellite turned from white to red.. Was this the tracking program saying that the satellite has now left orbit and has descended to Earth ?? This was over grid RH91 north of New Zealand at a height of 163 Kilometers .. The cross is still red on SATPC32 .. Jack-Kc7mg
