Re: Power to send data to a cubesat
by Wilson Convery 24 May '21

Hi there On voice, I was always told that your signal coming back should be no stronger than the satellite beacon. Not always easy to gauge, but a good starting point. If you follow the first rule then radio power output will be dependent on the antenna used to transmit. Obviously, if you are using a pair of crossed dipoles then you will need more power than if you are using say a large X-pol yagi. I guess this doesn't quite translate across to data modes, but If the satellite hears you and responds then that is at least enough power, so try reducing it until it stops working for you. Cheers Wil. G6WQN

New install of SAT PC32 stuck on satellite view?
by Bill Fastenau 23 May '21

23 May '21

Hi Folks, Just got some quick and appreciated assistance from AMSAT HQ folks, lost 2 shack computers and with them my registered SatPC32s and the files with the registration code- Paul got me squared away in less than a day, and over the weekend on top of all that... Reloaded SatPC32 v12.9 on WIN 10, install went OK, registration code was no problem. Set my observer location and expected the display to center on my location but it seems stuck on the center on satellite view. Tried center on Greenwich as well, no luck. I hit OK after selecting, no change, then selected STORE after verifying the setting was on Observer, then reloading. I have an X, or crosshairs on my location but the display continues to center on satellite. I rebooted the machine, uninstalled and reinstalled SatPC32 and read through the manual and FAQs pretty thoroughly, gotta be missing something- Anyone have any ideas? I'd appreciate any suggestions. Once this is squared away then I'll start fooling with the 9700 and rotor control... Bill WB2QGZ

Folks using a handheld and an Arrow antenna to work the FM satellites: What SWR do you have with that combination? I'm checking to see if everything is working right on my set-up. You may reply off-list if you like. Thanks! Steve AI9IN Oldenburg IN Grid EM79ji

ARISS is thegroup that puts together special amateur radio contacts between students aroundthe globe and crew members with ham radio licenses on the International Space Station (ISS). This will be a Multipoint Telebridge Contact via Amateur Radio between the ISS and students fromWindsor School and Liceo Industrial de Valdivia High School. Students will taketurns asking their questions of ISS Astronaut Mark Vande Hei, amateur radiocall sign KG5GNP. English is the language that will be used during thecontact. The downlink frequency forthis contact is 145.800 MHZ and may be heard by listeners that are within theISS-footprint that also encompasses the ARISS radio telebridge station. ARISS team member Jan Poppeliers, in Aartselaar,Belgium using radio call sign ON4ISS, will serve as the ARISS relay amateurradio station. Each student asking a question on the ARISS radio will be conferenced in and social-distanced at school. TheARISS radio contact is scheduled for May 25, 2021 at 2:33 pm CLT (Valdivia,Chile) (18:33 UTC, 2:33 pm EDT, 1:33 pm CDT,12:33 pm MDT, 11:33 am PDT). WindsorSchool and Liceo Industrial de Valdivia High School located in Valdivia, Chilewill involve about 500 students (ages 11 – 18 years) in this ARISS contact. Itwill be the first-ever Chilean ARISS contact. Both institutions have modifiedtheir STEM curricula to include studies related to space exploration/scienceand radio communications. Projects and activities engage students in astronomy,radio science, robotics, and satellite-tracking software. Selected studentsparticipated in the Houston Association for Space and Science Education STEMprogram. The schools have partnered with members of Radio Club Torreones(amateur call CE6RTV) who will support the activities during this contact. Viewthe live stream of the upcoming ARISS radio contact at https://youtu.be/lS03hu-LI1E . _______________________________ Astime allows, students will ask these questions: 1.Can you see any human building from space? 2.What are the most interesting things you have seen while in orbit? 3.Has been there any Latin American astronaut in ISS? 4.What strikes you about space and what is something that you can currently see? 5.What do you like most about being an astronaut? 6.Do you think it is possible that human beings will be able to overcome theirfeelings of isolation and loneliness in order to colonize another planet? 7.What was your reaction the first time you were in space? 8.Has being in space changed your perception on how people live on Earth? If so,how? 9.What is the longest time an astronaut has been on the ISS? 10.What motivated you to be an astronaut? 11.What should someone study to get the opportunity to go to space? 12.How does fire move in space? 13.We saw in the news that you cultivated greens in space, how did the saladtaste?

Mobile/Portable Power for Roving or your house
by Robert Bruninga 23 May '21

23 May '21

The ideal Rover vehicle, and, as we enter hurricane season and prepare our mobile/portable ham radio capabilities, the announcement of the new Ford F-150 Lightening's home backup power adds an interesting capability into ham radio operations.. The extended range Electric F-150 has the same battery capacity as ELEVEN Tesla power walls at half the price and its like you get the #1 pickup in America for Free! The 9 kW of 120/240 VAC power available on its power port can power entire Field Days or the average American home for a week to ten days of emergency power!

MIR-SAT1
by Jean Marc Momple 23 May '21

23 May '21

Good Evening All, The first 3B8 satellite will be sent to the ISS (by JAXA) on the NASA SpaceX resupply mission-22 on the 3rd of June 2021 and will be deployed in June by the KIBO robotic arm. The callsign is 3B8MIR (MIR-1 meaning Mauritius Imagery & Radio-communication Satellite 1). Payloads are a camera and a digipeater (bent tube) which will be made available to the HAM community worldwide when satellite not downloading images or used for experimental purposes, the uplink will be on 145.9875 MHz and the downlink on 436.925 MHz, 9K2 GMSK, as coordinated with IARU. More information will be available on https://spacemauritius.com <https://spacemauritius.com/> soon. Will keep you updated on the progress. 73 Jean Marc (3B8DU)

PSAT2 unknown resets?
by Robert Bruninga 23 May '21

23 May '21

I notice the S#0056mm orbit counter is at 56. The "mm" are minutes into the present orbit. And at 14 orbits per day that means the system reset 4 days ago on the 18th. No big deal, but Come to think abouit it, I have not seen orbit numbers get very high.and never past S#01XXmm I dont think. Its been 26 days and it should have gotten up to 360 or so by now (though we did send a few reset commands ourselves early on.. Bob, WB4APR

Anyone else having problems with the list?
by Mike Herr 22 May '21

22 May '21

I am getting strange results from the list - digest style. The digest lists all the emails but the actual digest does not include them. Another comment is it is difficult to find individual email in the digest as they are not listed numerically. One has to look at everything to find a particular email. -- Mike Herr WA6ARA
