Subject: Re: Link budgets for upcoming HEO/GEO sats
by Bob Freeman 11 Apr '16

Hello, Have been monitoring the link budget discussion and have questions about polarization. Unlike the 2m and 70cm LEOs, I assume the spacecraft will be stabilized with a fixed polarization and not susceptible to Faraday rotation. What polarization is planned for the satellite for up and down link and do we need to start designing polarizers for the link? Keep up the great work! Regards, Bob KI4SBL http://ki4sbl.dodropin.org/CNCTRK

Tried ISS SSTV but nothing heard
by Koos van den Hout 11 Apr '16

11 Apr '16

In one of the articles about the current ISS SSTV event was a starting time of 19:25 UTC, and the pass over my QTH JO22NC started at 19:28 UTC. So I was out with the whole setup and a strong arm to aim the antenna at the ISS in the hope of receiving something. But nothing was received. The fun part is that an ISS pass shortly after sundown gives a visual aid to aim the antenna at, but no signal received. Also noticed at http://www.dk3wn.info/p/?p=70934 -- Koos van den Hout PGP keyid 0xF0D7C263 via keyservers IPv6: Think ::/0, act ::1. http://idefix.net/ Are you ready to start supporting IPv6?

Channel master rotor
by jeffory broughton 11 Apr '16

A rotor needs to be able to provide feedback voltage to the controller. This rotor does not.I did see a modification where a person added a 10 turn pot in the rotor motor driven off a gear to provide feedback voltage so the controller knows where the rotor is looking. jeff broughton WB8RJY

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.
