ISS SSTV - Orbit Boost
by Paul Stoetzer 20 Apr '16

20 Apr '16

Good morning, The ISS SSTV event is supposed to last until 11:35 UTC tomorrow morning aside from a school contact from 12:35 UTC until 14:30 UTC today. However, there is a 252 second firing of the Progress's thrusters scheduled for 12:22 UTC today for an orbit boost, which will cause your orbit predictions to be off a bit. 73, Paul, N8HM

Yaesu rotor maintenance
by Richard Lawn 19 Apr '16

19 Apr '16

While my IC-9100 is in the shop and as I await a new 2 meter antenna I decided to deal with what I had let go - rust on hardware and rust on the rotor elevation bracket. The good old Dremel helped to get 90% of the rust off the U shaped el rotor mounting bracket and el boom u bolts, but I'm wondering what to use to paint over these items to inhibit rust in the future? Any ideas other than rust oleum? I'll off course use stainless hardware to replace the cheap stuff Yaesu gives you as I did the last time I rebuilt the rotor. Also replacing both feed lines. I hope this will tide me for many many more years. 73 Rick, W2JAZ -- Sent from Gmail Mobile

ISS Beacons
by Jeff Moore 19 Apr '16

19 Apr '16

I don't know if I had set up my radio to "autobeacon", but several years ago I wanted to try and work the ISS via APRS Packet. I was on my way to a fox hunting demo that I was going to do and I figured the ISS pass would be done by the time everyone started to arrive for the demo. Initially I didn't see anything happening and as luck would have it, people started arriving early for the demo I was doing and I got distracted from the pass. Later as I was securing from the demo, I looked at the station heard list on my D-710 and realized that I had succeeded in bouncing a packet off of the ISS during that pass. There were a total of 3 packets listed from that pass, the response to MY beacon, and 2 other packets that were digipeated by the ISS. A live contact would be totally cool, but I was very happy just to get my beacon digipeated by the ISS let alone pick up 2 or 3 others.

Reuse, Interoperability, Portability, Code Complexity Survey - Reminder
by Brandon Shirley 19 Apr '16

19 Apr '16

AMSAT community members This is a reminder email for the Reuse, Interoperability, Portability, Code Complexity Survey. So far about 8 participants have completed the survey, and if you have I am very grateful. I would ideally want about 100-200 respondents, but I have had about 40-80 participants on the previous surveys. If I could get 40+ participants that would be great. This is the longest survey, please note that you can take it in stages as long as you resume or visit the link in the same browser on the same computer and you have cookies turned on as it will remember your session: no other identifying information is collected or stored. You can you use the link below to access the Reuse, Interoperability, Portability, Code Complexity Survey. https://usu.co1.qualtrics.com/SE/?SID=SV_79TOgGac3B4Z77f What follows is more information about the survey and is largely the same as what you have seen before. There is a chance to win some gift cards. Please see below for more information. The survey should take about 15 minutes. Thanks. Please note that the link is anonymous, so you are getting this reminder even if you have already taken the survey. I would like to thank everyone that has participated thus far, I really appreciate it, I know it is an inconvenience and that everyone is really busy. The second part of the survey has background questions that will give context to your answers. Try to fill the background out the same way if you take more than one of the surveys. Answer as many of the questions as you want and as much of each question as you want, partial surveys may still be very helpful. At the end of this survey, you will be redirected to a webpage that asks for an email address. You must enter a valid email address to be considered for survey drawings or the overall survey set drawing. We are currently on the 5th survey, Reuse, Interoperability, Portability, Code Complexity Survey. You have a chance at receiving a gift card for participating in this survey as well as a chance at receiving a gift card for your overall participation in the entire survey set. There will be 2 winners of $25 gift cards for each survey and 2 winners of $200 gift cards for the survey set. The surveys are as follows and will be distributed in the following order: (participate as your mood strikes you) SISDPA : Core Concepts SISDPA : Development Preferences SISDPA : Open Systems Architecture and Modularity SISDPA : Security SISDPA : Reuse, Interoperability, Portability, Code Complexity <== We are here ==== SISDPA : Network V/R, Brandon Shirley b.l.s(a)aggiemail.usu.edu<mailto:b.l.s@aggiemail.usu.edu> See http://brandon.bluezone.usu.edu/Files/LOISpaceSoftwareAttitudes_Final.pdf for the Letter of Intent (LOI) that explains your role as a participant should you choose to participate. This is a legitimate request for you participation, if you have any questions about the validity of this email you may refer to the Letter of Intent, contact Brandon Shirley via email at b.l.s(a)aggiemail.usu.edu<mailto:b.l.s@aggiemail.usu.edu>, or contact Utah State University's Internal Review Board administrator at (435) 797 - 0567 or email irb(a)usu.edu<mailto:irb@usu.edu>.

Re: [amsat-bb] ISS Beacons (APRS-FAQ!)
by Robert Bruninga 19 Apr '16

19 Apr '16

Re ISS beacons: Here is the beacon gouge for APRS via ISS APRS was designed for channel sharing using the ALOHA protocol. That is, peak success occurs at around 20% channel capacity. For 1 second packets, that's only 12 packets per minute per digipeater area. This usually means maybe 5 mobiles at a 1 minute rate and 30 other home stations and weather stations, etc at a 10 minute rate using 1 hop and 60 other assets beaconing every 30 minutes when using the maximum of 2 hops. But on ISS, the digi neighborhood covers the entire USA at once! So, it is a travesty that people transmit unattended beacons via the ISS at such high rates causing nothing but interference with those trying to actually operate the pass. See the original APRS-ISS FAQ: http://aprs.org/iss-faq.html It recommends 1 beacon per minute for LIVE keyboarders, 1 beacon per 2 minutes for active special live mobiles engaged in travel or special operations, and one beacon per 5 minutes for unattended status/position reporting. The goal is to optimize the channel for live operators during a pass but for non-moving remote unattended position/status packets to be successful only about once a day (NOT every pass!) on http://ariss.net Bob Bruninga,wb4apr

ISS Unattended Beacon Theory (UBT) - PROVE ME WRONG!
by Clayton Coleman 19 Apr '16

19 Apr '16

I worked an ISS pass earlier tonight on packet. I copied 18 stations digipeated via the ISS. However, only one of them responded to any kind of live, keyboard-to-keyboard action. The other stations seemed very dedicated to letting the world know their name and city every 1-2 minutes. Surely my theory that 80% of the stations are unattended beacons, pass after pass, must be wrong. Please, prove me wrong at 0200Z 19-April, and show me that people have two-way QSO's and not just beacon their name and city continuously for 24 hours. 73 Clayton W5PFG

They are not only on satellite i stumble on one of them today VE2?? who was complaining about a reception report i gave him in a way to improve his signal audio quality over the air. He dislike my advices!!! Probably he failed to listen himself as he's probably some sort of a Joe know it all? Anyway i'm a bit off satellite business probably too busy watching south border TV...
