[amsat-bb] Re: ARISS Contact
Hi all, Thanks for the signal reports for today's contact with Central Square Middle School. Here is what I do know at the moment: The contact scheduled for 14:05 UTC only had about 3 questions get answered and the contact was cut short. A second attempt was then made at 15:40 UTC and it is my understanding that it failed. Sorry I was not able to get the word out for the second attempt but as I was just about to do that I had a work related call that took precedent and lasted for about 45 minutes. It is my understanding that many of you heard the ISS quite loudly, so that is good to know for us as we determine what happened. Thanks again to all for their reports. 73, Charlie Sufana AJ9N One of the ARISS mentors In a message dated 3/3/2014 9:34:45 A.M.

He said he was catching a few words and their signal was weak. By the time everything was ok, they had 2 minutes for the contact. From my location, the astronaut only had time to answer 3 questions. I recorded the pass. The ISS was very strong.

[amsat-bb] Looking for help for a school in Indiana County PA for an upcoming ARISS contact
Hi all, I am mentoring a school in Indiana County PA that is going to have an upcoming ARISS contact. We don't have the school scheduled yet but it will probably be in early 2014. If you can provide some help with equipment, then please let me know and I will forward it on to the school. Thanks for the help. 73, Charlie Sufana AJ9N One of the ARISS mentors ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: hams on ISS
Hi all As part of my volunteer duties with ARISS, I post the schedule of upcoming ARISS contacts on practically a daily basis. I post to the SAREX BB (_sarex@AMSAT.ORG_ (mailto:sa...@amsat.org) ). You can also check the schedule at _http://www.issfanclub.com/_ (http://www.issfanclub.com/) and at _http://ariss.rac.ca/_ (http://ariss.rac.ca/) (actually _http://ariss.rac.ca/upcoming.htm#NextContact_ (http://ariss.rac.ca/upcoming.htm#NextContact) and look for the link saying Tentative List of Upcoming School Contacts . You can also go directly to _http://www.amsat.org/amsat/ariss/news/arissnews.rtf_ (http://www.amsat.org/amsat/ariss/news/arissnews.rtf) . In spite of what some may think as to how up to date the schedule is, as soon as I get updates on the schedule and success of a contact, I usually have updates posted in less than a day. There are times when we get the locked down time from the ISS planners for a contact almost at the last minute so my heads up might be very short. Unfortunately we sometimes find out about the Russian contacts after the fact and thus I am unable to give everyone a heads up. Usually we at ARISS get the scheduled date and time about 10 to 14 days in advance but we warn all schools that we may get told with less than 36 hours. We have also been aborted with less than 10 minutes to go before a contact. We are often asked about when the crew is going to make a general contact. We simply do not know. The crew is super busy and when they do get free time, they have many things they can do. We can suggest that they get on the radios; we can never demand. So ham radio may or may not be in their game plan for that day. By the way, all of the ARISS school contacts actually take place during a scheduled off time for the crewmember. That means they either gave up some free time or their day gets extended. 73, Charlie AJ9N One of the ARISS mentors In a message dated 1/30/2013 7:30:56 P.M.

There is Internet access and a telephone to speak with family. I don't generally get into these types of verbal banter, but this time I make an exception. Right now a Canadian, Chris Hadfield, is onboard and doing a great job with pictures and Twitter. I see today that he did a live feed to a school here in Ontario. The part that bugs me is there were a few ARISS Ham contact before Christmas that did not show up till the day of the contact. The Canadian RAC site had no mention of it on their site and still is stuck in November. I read a lot of AMSAT/ARRL news letters and I have suddenly realized that the ham community is out of it altogether. It would appear that starting this year NASA themselves is looking after the contacts. I would have thought that the ham community would have been in an uproar over this, guess not. I know that the chances of hearing or contacting the ISS is like winning the lottery, but I think now it is long gone. I am disappointed that when an USA or Russian is onboad you may hear them once or twice. I doubt that you will ever hear Chris at the mic. he seems to be caught up in social media. > I'm not sure what the definition of a real ham is but too many times it seems >to be a person stuck in the past, bemoaning the things that used to be No I do not feel that way, I try all kinds of stuff when I have the time.

[amsat-bb] Re: Polarization for ISS and Weather Satellites
The antennas on the ISS are ground plane type antennas for 2m and 70cm. So one could just say that the antennas are vertically polarized. However, the ISS superstructure has gotten so big that it does actually block or reflect the signal between the ISS and the ground station. So we recommend that a circular polarized beam be used as the polarity changes throughout the pass. I think most of the ARISS schools have used RHCP but there have been a few where switching to LHCP during the pass did help. As a side note, the ARISS schools are to have a backup radio with an antenna that has no moving parts. Usually that means a 1/4 wave vertical. I use a vertical and an Eggbeater for my school contacts with an antenna switch between the two. You might want to do the same thing with a Quadrifilar and a vertical. I always tell the backup radio operator to switch between the two during the pass and go with whichever has the greater signal strength. They are usually stunned by the change in signal strength between the two as the pass progresses. The signal with the beam is much more stable and stronger as expected. Hope this helps. 73, Charlie Sufana AJ9N One of the ARISS mentors In a message dated 10/27/2012 2:31:27 P.M. Pacific Daylight Time, gdillabo...@nf.sympatico.ca writes: I haven't posted here in a very long time. I hope this works. I am building two Quadrifilar Helix antennas (from QST, August 1996); one for weather satellite experimentation, and one as a backup antenna for an upcoming ARISS contact. I haven't found anything in the ARRL antenna book, or on the web, that specifically says that one mode (RHCP or LHCP) of circular polarization is better than the other for either of the two applications noted above. Any insight or experience with polarization issues with the ISS and weather satellites are appreciated. The last time I did an ARISS contact, I was plagued with very deep fades, and want to do better this time.

[amsat-bb] Re: JOTA and ISS
The ARISS schedule is updated quite often. I do post an announcement to the SAREX BB of the updated schedule. You can always go to http://www.amsat.org/amsat/ariss/news/arissnews.rtf for the complete schedule. The Boy Scouts will be having an ARISS telebridge contact via VK6MJ in Australia. Below is an excerpt from what I have already posted. National Scouting Museum, Irving, TX, telebridge via VK6MJ Contact is a go for: Sat 2012-10-20 18:32:30 UTC 66 deg As far as JOTA goes for general contacts, we tell the crew about the weekend but we cannot demand that they participate. So if you hear them on and can work them, go for it. Happy hunting! Just realize that any general contact as well as the scheduled ARISS contacts take place during a crewmember's off time. So if you can work the ISS, please thank them for taking time during their off time. 73, Charlie Sufana AJ9N One of the ARISS mentors In a message dated 10/16/2012 2:58:15 P.M.

I will be operating from Galveston State Park in Galveston, TX. Also, does anyone have info on when the ISS will be in contact with the Boy Scouts in Irving, TX this weekend? I understand they have a schedule set up and perhaps we can give a listen. Perhaps on the next pass or so, they will consider a contact with others. 73, -james W5AOO ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: NA1SS Chats with Lompoc, CA
Hi all, I post all upcoming ARISS contacts times to the SAREX BB. You might want to subscribe to that one if you don't already. You can also use the link that is posted on the AMSAT main webpage. Yes, you were hearing Lompoc have a great contact. The ISS crew will ignore any callsign it hears except for the school one. Plus they are not using the public uplink frequencies. We welcome all listeners; that is why the 145.8 MHz frequency is used for all voice contacts (general or school). Perhaps this will get you started getting involved with a school that may want to do an ARISS contact. Thanks for listening! 73, Charlie AJ9N One of the ARISS mentors In a message dated 9/29/2011 11:48:48 A.M.

I rarely try to work the ISS but thought I would give it a try and manually swung the antennas over to the correct azimuth. I heard some chatter and was initially irritated that someone would be having a QSO on the downlink frequency but then from the conversation I realized that it was someone on the ISS describing seeing hurricanes in the Pacific. I could not believe my luck that NA1SS was actually working contacts! Not being able to hear the uplink, I gingerly threw out my Callsign a couple of times hoping to get into the rotation and then to my great embarrassment, it became apparent that NA1SS (Mike Fossum) was working a school contact in Lompoc, CA. I sure am glad that I just threw out my callsign twice before I clued in on things. At any rate I was able to monitor NA1SS down to about 3 degrees.really clean, strong signal. First time for me hearing the ISS because I rarely check it out and typically don't have SatPC32 even tracking it.

SatPC32 and Nova both support Flip mode directly. Just follow the instructions within the programs on how to do the set up. 73, Charlie AJ9N In a message dated 9/4/2011 1:28:05 P.M. Central Daylight Time, wa4...@amsat.org writes: I believe the G5400 is a 360 degree rotor control. If you are wanting to go from West through North to East, you will hit the stop. Two options come to mind. Put the stop at South, but this gives the same problem going from West to East though South. The second option is a program like FLIPANTS that turns the antenna on it's back and turns the Az control plus/minus 180 so that the stop is not a problem. Decide if the "through North" or "through South" will become a problem and make a choice, then use the software to overcome it. Flipants is a old DOS program, but I think you can find an equivalent available.

At this point in time we do not know active the new crew will be. As with every new crew, the crew is off limits for a few weeks once they have docked to allow for them to get acclimated to space and learn their way around the ISS. The first scheduled ARISS school contact with the new crew is Università degli studi di Bari “Cittadella Mediterranea della Scienza”, Bari, Ba, Italy, direct via IZ7EVR slated for Sat 2011-01-08 12:21:55 UTC 41.2 deg. So look for activity starting about then. As always, I attempt to keep everyone up to date with the latest schedule when I post to the various bulletin boards.
