Re: [amsat-bb] SatPC32 Question
Hi Erich, Yes! I had downloaded but not yet installed (don't know why) 12.8c on my desktop PC back in January this year. When I went to do the upgrade yesterday, I first was going to copy the zip file from the laptop but when I saw the same version already in the downloads on my desktop PC I just unzipped and ran that one. So I redid things now with the June download of the zip file and everyone is happy! Thanks for your time and help. 73, Jerry N0JY On 6/9/2014 1:35 AM, Erich Eichmann wrote: Hi Jerry, I added the "Start with Gt+" feature in Febr. 2014 - a suggestion of Ron, W5RKN.

[amsat-bb] Re: N American Satellite Activity UP
When Fox-1 is completed, the whole design kit and kaboodle will be published to shed the ITAR shroud (as we have done with what has been developed as we go along, in the AMSAT-NA Space Symposium Proceedings) and anyone who wants to build one can use it or adapt it (hopefully keeping the ham transponder!) for their CubeSat RF design and fly it in/from/for another country with their experiments. The idea being as JoAnne said, the radio part is proven and provides a platform so they can concentrate on their experiments and build a CubeSat that handily just happens to contain a transponder for hams during, or when they are done with, their experiments. Of course if ITAR restrictions are eased or removed, then AMSAT-NA could collaborate with other countries as well and incorporate their experiments as we are doing with our U.S. partners now. Jerry N0JY On 3/28/2014 8:31 PM, JoAnne Maenpaa wrote: Hi Bernhard, Now if I could only convince them to include a transponder for us hams ... FUNcube boards and the AMSAT-NA Fox-1 boards include the capability to transmit telemetry data modes and support a voice transponder. Not sure what ITAR issues prevent Fox-1 boards being used in other country's satellites. The Fox-1 boards supply the avionics radio half of the satellite leaving the students to concentrate on designing their scientific payload. Fox boards have a documented interface for experimenters to use. FUNcube switches between ham voice/cw modes and full power telemetry. Fox-1 boards would provide the capability to support both voice and low-rate telemetry stream simultaneously or switch to a high speed data link with no voice. -- 73 de JoAnne K9JKM k9...@amsat.org Editor, AMSAT Journal ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: status
One thing I overlooked is good old ITAR. Hell, I'm even afraid to tell my friends around here what I do for a "living". I'm pretty sure that AO-73 was a collaboration between AMSAT-UK and AMSAT-NL, a luxury that we don't have. Plus, we are limited to U.S. launches and some of them (i.e. Fox-1A) have a LOT of restrictions and paperwork on them, a whole 'nother full job of volunteer work. I spent weeks working on the paperwork for the license (yes, we need a license because it flies from the U.S.) for the camera experiment. That being said, there are no opportunities to share with other AMSAT organizations on development and if coming up for volunteers to build the satellite is so difficult then that also applies to other opportunities such as ground station solutions. Manpower... Can't even share details about "this is what we would like the satellite to accomplish can you (AMSAT-notNA) help with some ground station design ideas". As has been pointed out if anyone has any ideas go for it, but realistically it should be something that you can offer a solution for. Throwing out ideas is great, maybe some things have not been thought of, but that's just like saying "and here you go do it". Get a group of people interested in accomplishing it, at least come up with a conops, requirements... even if you can't build it (and believe me, I am waaay past the age of seeing some of them teeny parts much less avoiding scattering them to the wind when my allergies kick up a good sneeze) there is something to work with when someone comes along who can build it. And those people are out there, but you need to get every aspect together, so that you have the people with the plans and the specs and the people who design the circuits and the people who get the parts and the people who put the parts together and the people who test it. It has to progress in steps. Start with those who can do the starting steps, build a team, and over time you can do it! People say (quoting you for recency) "why AMSAT is not..." but AMSAT is not a being. We are AMSAT. Saying "Why AMSAT is not" means "why I am not" (contributing, building, designing, whatever) "is a mystery to me." It doesn't have to be an official AMSAT-NA program I don't believe, look at what Mark Spencer WA8SME has done with the ideas based on the Fox satellite. 73 Jerry N0JY On 1/26/2014 12:16 PM, Michael wrote: HI Jerry, First of all, thank you for being civil. Nice change from the last two responses to my post. Second of all, I apparently stand corrected on one thing. It was my impression that Fox-2 was also intended to be another FM sat. If I am wrong in that then I apologize for the previous characterization that all AMSAT seemed to want to do is put up "flying repeaters". However, I will not back off my assertion that there should be more to this hobby than portable ops using HT's and handheld yagis.The Funcube bunch showed us not only that linear cubesats are viable but also that fairly inexpensive SDR technology is a great way to go as one option in receiving them. The Funcube and Funcube Pro dongles were also a great fundraising idea as near as I can tell. We should be taking concepts like that one step or even several steps further and developing SDR based ground station solutions just as we are developing SDR based transponders. Why AMSAT is not developing stuff along those lines is a mystery to me. I know AMSAT is volunteers but so is AMSAT UK and they got it done. I wish I had the technical expertise to develop stuff like that but I don't. I can certainly build with the best of them but circuit development is not my strong suite. It just seems all we ever do anymore is show folks how they can operate an " easy sat" with an HT. That's very frustrating to me. I apologize for the " idiot at a hamfest" comment too but really all I was trying to do was to express my frustration with that same old approach which has grown kind of tired and boring to me. 73, Michael, W4HIJ ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: status
Hi Michael, I have to defend AMSAT-NA a bit here, the perception that the organization is "bent and determined to keep building and flying FM repeaters" is not quite accurate. Fox-1 which is an "FM repeater" was underway over 3 years ago when AO-51 was failing. The purpose was to put up a quick replacement for AO-51's popular "easy sat" HT/yagi accessibility. In building such a project spares are necessary and hence there will be 4 Fox-1 type cubesats of which two are going to fly so far. They are all the same design with the difference being what experiments are loaded in order to get us that launch. The purpose of the spares is to have a ready replacement should one of the flight units fail at the last minute. We may then have up to four "FM repeaters" launched someday, but it's not because that's all we're pursuing. So it's not like we just keep building more FM satellites, we are just taking opportunities to fly what we have as the launches come up. And don't overlook the contribution of the experiments to the value of the satellite. While it may be an "FM repeater" they will carry some very interesting experiments providing telemetry and pictures for education and fun. In the meantime, there are still plans underway for AMSAT-NA to build a linear transponder SDR satellite as Fox-2 (series). That was the original idea until AO-51 started having problems. In my opinion and from the perspective of a participant in the Fox-1 project people way underestimate what it takes to build a RELIABLE and ROBUST satellite what will last many years, projects being completely done by VOLUNTEERS. There are many people spending all available spare time, pushing the limits of matrimony and family, and essentially on a shoestring budget due to limited finances (i.e. contributions, memberships). Those limitations of available resources mean slow progress. And the resource limitations also mean that nothing will probably happen on the linear/SDR satellite until Fox-1 is done and launched. Volunteers are not crawling out of the woodwork, and many who have signed on have come and gone or had to regulate their participation due to the need for real life as in jobs, family, and so on. Opinion is entirely mine, and any misrepresentation of AMSAT-NA plans that I may have stated is not intended. 73, Jerry N0JY On 1/26/2014 10:48 AM, Michael wrote: I wasn't going to touch this as I've made my opinion about P3-E known before but I can't be silent about some other things. I don't believe it will ever fly because of the economic realities of today's world but hey, stranger things have happened. Cubesats seem to be the wave of the future as they are more affordable to get launched but if you ask me we are still going in the wrong direction with them in a couple of areas. AMSAT seems to be bent and determined to keep building and flying FM repeaters even when ground based FM repeaters are slowly falling into disuse and projects like Funcube AO-73 are showing how viable linear transponder cubesats are. There also seems to be some continued fascination with showing how we can all stand out in the frigid cold or the blazing sun balancing an HT in one hand and a handheld yagi in the other to work the flying repeaters... YAWN!!! The novelty of that has worn off just as quickly as it did on exchanging nothing but grid squares and calls and calling it a sat QSO. The focus not only needs to be on more linear transponder cubesats and developing new and efficient ways to communicate with them but also on developing affordable ground equipment like complete SDR transceiver systems along the lines of the funcube dongle except maybe abandoning the "dongle" concept and going more with a desktop "black box" approach. A computer driven SDR base station with tracking and doppler correction and digital and CW as well as voice mode communication is infinitely more interesting to me than seeing some idiot balancing an antenna and an HT at a hamfest.

Yep I'm definitely hearing stations again tonight, even with the preamp off. It may be an image, I can see the same QSO up higher on the spectrum display at about the same offset from the center frequency 145945 so that would make it about 145957 or so (give or take late night calculating) and that is in the transponder window. Stations appear much stronger on the spectrum display than the rest of the bumps. Jerry N0JY On 12/6/2013 10:37 AM, Darren Long wrote: I also observed something like this the other day.

[amsat-bb] Re: D STAR
I use D-STAR Digital Data on 1.2 GHz for my Winlink RMS Packet CMS connection, 24/7. The Pactor 3 mode that I use for Winlink HF forwarding is proprietary. But nobody else has come up with anything near as good (yet). So a lot of hams use it because it does the job well. We use D-STAR DD 1.2 GHz as a backup to the local internet connection for EMCOMM at the EOC and I do the same at home, too. WebEOC for example. D-STAR is another tool in the box, another readily available method that might be better in a particular circumstance. Why limit myself by not having a set of metric sockets for my wrench?

[amsat-bb] Mark Spencer's AMSAT Journal Articles
Through his work on the educational aspects of the Fox satellites, Mark Spencer has produced some great experiments and materials. The Fox-1 attitude determination experiment, and now the Fox-2 MPPT system have both been presented in the AMSAT Journal. If you aren't a member of AMSAT you are missing some great stuff in the Journal. But in this research and work for the Fox-2 MPPT system I believe that Mark may have inadvertently answered an age old question that has (to my knowledge) never been definitively been answered before. A question as old as the icebox itself. In the MPPT article figure 3, Mark presents a measure of voltage and power in three environments: a room (presumably in his home), the refrigerator compartment of his refrigerator, and the freezer compartment of his refrigerator. The measured power is higher in the refrigerator and even higher in the freezer. EUREKA! I believe that Mark has finally proven that the light in the refrigerator (or freezer) STAYS ON WHEN THE DOOR IS CLOSED! Otherwise, how could there have been any power output in the refrigerator or freezer at all? A solar panel requires light to work. Thank you, Mark! I can now share with my mother (poor Pop isn't around to enjoy this discovery although he first posed the question to me 50+ years ago) that I KNOW. And keep up the good work that you are doing for the ARRL Education and Technology Program too.! 73 Jerry N0JY (The above was for fun and in no way meant to diminish Mark's work.) ___ Sent via AMSAT-BB@amsat.org.

Yes, and this is one of the goals of the Fox project too! We can partner with the universities, providing the transponder and bus (Fox-1A, RadFXSat) which may be dedicated to their experiment for some years or not, depending on the downlink needs (i.e. Fox-1 has high speed for youse guys, and the slow speed accommodates Vanderbilt). We have a transponder dedicated to ham use when the experiment(s) are through or even while they are going on. Or once Fox-1 is finished and all of the details are published, any institution could use the design for their project and "give back" (as a gesture of kindness for all the work we saved them and excellent science we helped them gather) the transponder when they are done with their science. It gives them a proven reliable system that they don't have to engineer on their own. It gives us another transponder if not on launch, at least eventually.

[amsat-bb] Re: A0 40 replacement
Hi John, The reason that Fox-1 is an FM transponder is because it was designed to be a quick replacement for the popular AO-51. The move to a linear transponder in our first cubesat will require time, and learning. Boy, if we could work together with other hams around the world to learn and design bigger and better things... but we can't. So we're going to have to learn it ourselves, and Fox-1 also provides a step in that direction. Take my word for it, building a reliable, long life cubesat is not as easy as it sounds. If I recall correctly though, the original idea was for a linear transponder and that is still the longer term goal for the Fox series. Fox 2, after learning from the successes or failures in Fox-1, will be that. And I speak only from what I have learned from reading and being involved in AMSAT. I am not a spokesperson, and everything I am saying is public knowledge that was available to everyone here. This story has been told before...

[amsat-bb] Re: High orbit satellites?
In fact many, many VOLUNTEER hours have been put in by the AMSAT leadership to get the two launch opportunities we have for Fox-1 and RadFXSat. You wouldn't believe the work involved. They deserve a big thank you for getting that done for us! It would be wonderful to share everything going on "behind the scenes". To keep everyone updated often, on what the state/progress is. But for a few reasons, it doesn't quite happen that way... Number 1 reason the many, many volunteer hours just spent on the project means that the rest of the time is spent on those things outside the hobby like a normal person. I mean, how often do any of us sit down and write a detailed letter to the BB about our AMSAT activities over the last week or month? If we had a PIO that could relate the Fox-1 happenings to everyone... well, everyone would each still have to spend time telling the PIO what they have been doing! There are a lot of people working just on Fox-1, scattered all over the United States. I'm sure everyone who has done weekly status reports knows how fun that is. Number 2 reason, ITAR. Perhaps you say well Jerry, you just spent time writing this email... Then in the same amount of time I could tell you without jeopardizing the project, AMSAT, or my prison-free existence, after sitting for a few moments to recall what I did over the last week or two, that I worked on a lot of system bus changes and their related document updates (the same Fox-1 documents you read in the 2012 Symposium proceedings) because of design evolution, I worked on the downlink specification (how we're going to get all of the wonderful telemetry and pictures to you and our university partners), I researched and worked on changes to systems interfaces (design evolution again) and updated those documents, checked up on requirements tracking (very important to be sure we don't miss anything), and worked on test procedures. Talked to Tony on the phone, had an IHU software team conference call. Emailed a lot with other Fox-1 team members. And yes this took me about 10 minutes to recall and write here. Was any of what I said about what I did of interest to this group? Maybe. Useful information? Not so much. Something you want to hear about on a regular basis? Probably not, there's not much real value in what I just said. I doubt that any of us working on the project are very good at "sound bites". That's not what we get paid* for. Now add to that the fact it would take more time to relate any of the details of what I did and even more time to determine what details I might safely relate in respect to ITAR, writing a letter to the BB or even an article for the Journal about what just I did becomes quite frankly, something I don't want to do. And I imagine that holds true for a lot of us. I'll be working on Fox-1 some more now but later today I'd like to eat a snack and play a video game for a bit, then make supper for the XYL and spend time with her when she gets home from work if you please. Oh and we have another Fox-1 conference call tomorrow, hope the XYL didn't already have plans for anything around 11 AM. Fox-1 is moving ahead on schedule, and there are things of public interest to share which are documented on the AMSAT web site or in the ANS. That's all... I think it would be fair to say that the Fox Team are all as excited and anxious as you are to get these satellites built and launched! It is hard work. But I love my job!

I see it mentioned often that P3E is "essentially ready to go." If that's the case, why not press forward. As a relative newcomer, I'm often frustrated about the lack of updates about anything and websites that are wildly out of date. I know that everyone is a volunteer and busy with other things, but would it be so difficult to send out an update about what's going on once in a while? For example, TurkSat-3USAT was launched back in April. There have been absolutely no updates from anyone about what happened. Obviously the beacon is not transmitting and the transponder is not on, but what happened? Is there hope for recovery? If it has failed, the entire community could benefit from knowledge about what has happened so that similar failures don't happen in the future. Then there is AO-27. The website was last updated in January saying it will be several months before they know if the satellite can be recovered. A quick update would be appreciated, even if it's something like: "Due to time constraints, we haven't been able to attempt recovery." Things like this lead to the perception that this aspect of the hobby is dying. There is very little traffic on this reflector and not too much traffic on other web forums for amateur satellite operation. (See the QRZ forum topic "Is AMSAT dead?")

[amsat-bb] FO-29 success
That was a pretty good pass, given that I think I fried my preamp (enthusiasm should always be tempered with a checklist!) and I was aiming through the house here for the entire pass without the preamp then. I guess the chicken wire stucco didn't hurt as much as I thought it would have. Five stations in the log on that one, CO6CBF K4FEG K8YSE KB5AAB K4YYL the next pass about 03:10 UTC here will be another out the window pass although that is shooting over the mountains so LOS looks to be about 03:24 UTC here because of the mountains. I'll upload to LOTW after I return to the U.S. (and recover) later this week and make some QSLs if you want a paper one. 73! Jerry HK5JY ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] E for Effort? From FJ13
Well, that was not nearly as productive as I had hoped! By the time I got some decent signals from the U.S., the elevation was taking me down back into the QRM from all of the city around me. I copied Frank, and tried to pull out one other who I heard as AA5VK but wasn't, sorry folks, the signals were just in the noise from the QRM even with the AMSAT broadband preamp. I see an email from Glenn AA5PK now, well if we do it again tomorrow at least my ears may have a better idea what your call is! Looking at opportunities tomorrow there is a nice AO-7 7/2 at 22:22 UTC here that covers a lot of the U.S., what mode will it be in? We have an SO-50 7/2 at 00:54 UTC here that catches the southeast U.S. before my LOS but I'm shooting through some buildings, maybe the lower orbit will make up for that. Then FO-29 again 7/2 at 03:10 UTC here that skims the top of the mountains to the west, which might be better than tonight because more of it is out the window rather than through part of the roof... it gets into the southern U.S. Thanks to all for trying this with me, I'll look for you again tomorrow night.

[amsat-bb] FO-29 from FJ13
There is a good pass of FO-29 over my QTH tonight, starting 7/1 at 02:19 UTC. I expect to be on the bird on SSB. I have many constraints here, operating inside the house for safety reasons and surrounded by mountains and buildings which mean the bird must be at least 20 degrees up for me to see it. There is also a lot of QRM from uncontrolled devices here. I'll probably hit LOS due to the terrain about 02:35 but it looks like FO-29 will give coverage of the Southeast U.S. from Texas to Pennsylvania at that time.

I did it at field day last year, a couple of Arrow antennas with the 2 meter side set up for RHCP. Seemed to work real well on the analog birds. Some 75 ohm coax does the matching, see a picture at http://www.n0jy.org/images/IMG_20120623_215906.jpg The picture was taken at night, so look closely and you'll see a 1/4 wave 75 ohm section at the tee to both sides, the right side directly to the antenna and the left side to another 1/4 wave 50 ohm section connected to the antenna.

At any given moment, you only have 1 chance in 90 that you will have matching polarization. So, if you plan to use the antenna for other than Satellites, set your polarization for that purpose (V for FM or H for SSB/CW). My plan is to install 2 Elk antennas, one V and one H. Then, have a relay that I can switch between the two and choose the best downlink signal at any given moment. This arrangement will also give me optimum flexibility for terrestrial operation on 2 & 440. Now, where can I find a relay to do that function? 73/GL,Bob K8BL --- On Tue, 4/16/13, Lee Maisel wrote: From: Lee Maisel Subject: [amsat-bb] Re: Mount an Arrow on rotator with 2m vertical or horizontal To: "Don Hoover (WS4E)" Cc: amsat-bb@amsat.org Date: Tuesday, April 16, 2013, 12:24 AM Hi Don, I have mine mounted with 2m elements horizontal, because that's how it seems I used it most when it was handheld.

Hi All, I am planning a similar operation with the Tri-County ARC (WC5C). There are a few of us who get on satellite and we are going to bring out all manner of antennas from Arrows to Lindenblads to small yagis to big yagis, and while having a "reliable" station with the bigger antennas and FT-736R we plan to let anyone and everyone try their radio be it an HT or an all band rig with the antennas we have or whatever they bring, to experience listening to any maybe making contact (no promises) through any of the satellites. An opportunity to see what can be done with various levels of equipment/investment/skill and learn about how the different satellites/antennas work in various conditions. A free for all but backed up with some more "reliable" Q for those who want to sit down and try the linear birds as well as making some FD points. It should be crazy! But I hope to give lots of people the opportunity to play rather than in the past, where many would just watch quietly as we operated and ask questions now and then. Many are shy, but given encouragement and a challenge I think they might like to see what they can learn and accomplish hands-on. 73, Jerry N0JY On 6/22/2012 6:31 AM, Philip Jenkins wrote: Thanks, Mark.

One small precaution, based on personal experience during Field Day---be careful about creating expectations that can't be delivered...in other words, using the handheld system to listen to an FM bird is pretty easy, but on Field Day, it might be impossible to get a signal into the bird for a real contact. When I've done demos on Field Day, I warn my observers that it's going to be quite busy, and while we certainly will hear the bird, it's unlikely with 5 watts that I'll make a contact *today*. But letting them hear the busy bird gets them interested, and has led to invitations to give a presentation/demo at a local club meeting---which CAN more easily lead to making some contacts (especially if you announce the event here on the BBS. People will look for you specifically, in order to make your event successful). If you're going to have both the TS-2000x and the little radio, you could have somebody else waving it around to listen, while you operate the transmitter. It's fun to have audience participation!

[amsat-bb] ARISSat-1 R.I.P.
Applause and accolades to the ARISSat-1 Team, for the tremendous amount of fun, excitement, opportunities and activity that ARISSat-1 provided! I got hooked at launch, listening/watching on the internet even as I was also on HF that day conducting an exercise with the local and state R.A.C.E.S. teams and the local nuclear power plant during the launch. I started tracking and gathering telemetry a few days later and dedicated a PC and my sat station to automated telemetry gathering 24/7. I split off the 2M signal to my FT-817 and captured hundreds of amazing SSTV pictures. I enjoyed watching the telemetry decoding program on my PC showing the live readings. I followed especially in the last days, on the arissattlm.org web site. Much of this excitement I shared with my local ham radio groups in meetings and on the air, with local children and non-hams, and even in Colombia over Christmas I engaged some of the family with listening for the "secret word" in Spanish. A few attempts were made when I had time, to make contacts through the transponder. I heard myself and others, and had a part of a QSO... but never got that complete QSO. I became so engaged with the telemetry that near the end, I wrestled with the decision to try a transponder contact or to keep copying telemetry in hopes of the "last telemetry" award! Thank you very much, all who made ARISSat-1 possible. Your work was very fruitful indeed. I look forward to the Fox family and hope that we can keep up the enthusiasm and support necessary to stay on the air in space! 73, Jerry N0JY ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: 2 Meter TV Interference
Hi Wyatt, How far away is your neighbor? I TVI myself when I transmit on two meters, I have a Winlink station running 50W into a J-pole about 20 feet away from my TV antenna, in the attic. We are on the fringe of the OTA TV coverage, so I have a high gain TV antenna with a preamp. I also installed an ICE 437B filter. It appears that since the two are in such close proximity and the TV signals are so weak, that it doesn't take much to tile the picture or freeze it for a moment on some of the channels. Such is the nature of it. Most of our HDTV is on UHF, but channel 8 is on channel 9 (VHF). Some days the TV signal is stronger, and there are no problems. Most days, just the opposite. I have no big solutions, just an observation, but you may be able to mitigate the problem if you move off to the side of his antenna or further away from his antenna, or decrease your power. And maybe one other solution. Fox-1 will have the uplink on 70cm, so that might make you both happier! 73, Jerry N0JY On 12/6/2011 9:17 PM, Wyatt Dirks wrote: The problem occurs while I am transmitting.

Exactly! This is what I use, although I do use an RS-232 serial interface port on my PC but you could use a USB to RS-232 converter. It only has idiot lights to let you know that it is doing something, your rotator controller shows you the rest. It's kind of like having an invisible set of fingers controlling the switches! And if things get hung up, you can power off your rotator and power it back on and the ST-1 won't keep trying to move the antenna. My KCT would not let go until you shut down the tracking program, which was annoying because IF the antennas get hung up for some reason I didn't want them moving when I powered the rotator back on, what I needed to do was move them back the other way!

[amsat-bb] Re: knowledge required
Yes! Let's don't overlook the fact that designing and building an EasySat CubeSat also gives us the opportunity to explore, learn, and try out new technologies that can be later used for higher satellites when the opportunity comes, and expanded functionality on LEOs as well. I don't think AMSAT-NA is stuck in a dumbing down, or a "good old days" mentality, I think we're taking the lemons we have (although I don't for a minute consider ANY opportunity to build a satellite as lemons) and making lemonade, if you will. The art is still advancing. The fact is, it has advanced so far that it seems so EASY to many people (as did the Space Shuttle) that it appeared not much of a feat to send one up a few times a year. A handheld radio and a handheld antenna... "old timers" (and I'm one of them) would never have dreamed that they could reliably communicate over a 2000 mile path through a satellite with such ease and such simple gear, 50 years ago! By the way, 50 years ago Oscar 1 was launched and it was an amazing feat. Just 4 years after the first satellite ever was launched, hams were in space! We do this voluntarily, we do it because we love it, we do it "because it's there". That's what makes Amateur Radio so fun! 73, Jerry N0JY On 10/23/2011 4:27 AM, Luc Leblanc wrote: Words of Wisdom!

[amsat-bb] Re: AO-51 pass at 22:06 UTC 2011-10-01
An interesting account, Clayton. It reminds me of my shipboard contact with my ham radio club back in 2008. We had a contact on AO-51 scheduled, and at the appointed time I gave my call (between the current QSOs) and a handful of stations answered, I asked them to please stand by while I completed the scheduled contact and they were quite nice and did so. As soon as I finished the contact with the club I asked for the others and the contacts were fast and furious but really quite orderly. Whether that is testament to the perhaps fewer ops on AO-51 back then, or the courtesy of the operators, could probably be argued. I believe it was the latter, and coupled with the fact that there were fewer stations that could not hear the satellite, trying to call it anyway (which seems more common these days, just my observation) made it work. Being a "rare" grid (FL66) at the time everybody wanted to work, but a lot more people got to work because everybody was courteous and waited for the short QSO exchange to be completed. Even though my callsign VP9/N0JY/MM felt like about a 10 second mouthful... :-) My summary thought is the same as yours: If I don't work this station/grid right now, is it really the end of the world? A growing number of people (good ops) have satellite VUCC. And I probably wasn't planning on selling or throwing away my Arrow and HT (or home satellite station) 10 minutes after the contact opportunity, so since that guy is on a ship nowhere near land I'll bet he'll be out there on the air again when the satellite is in view of that area if he had a pleasant experience the first time. Or, if someone drove out to Armageddon Grid, if I really really need THAT grid, I'll bet someone will do it again if they had a pleasant experience the first time! It's all about the pleasant experience, the fact that the op is out there in the middle of nowhere is because they ENJOY doing that! 73, Jerry N0JY On 10/2/2011 8:56 AM, Clayton Coleman W5PFG wrote: Since I am relatively “green” myself to FM satellite rover operation, I will share an observation from a recent grid expedition in West Texas. I’ve observed a behavior that I refer to as “Armageddon grid.” This means the rover operator is activating a grid for the last time before the world meets a fiery demise and doesn't know it until he gives his call and grid square. This is an overview of an Armageddon grid activation: 1. Rover station calls one of his friends or scheduled contact. 2. Up to five stations immediately call the rover station in rapid procession, not allowing a millisecond between calls for anyone to answer. Never mind the opportunity of the rover’s original station called establishing contact. 3. At this point, the rover station tries to complete his original call (if/when the dust settles.) 4. Typically what occurs is step 2-3 wind up in a loop for a period of 2-3 minutes thus effectively reducing the usable time for other stations to make contact on the pass by one-third or more. If operators would not treat working a rare grid as if the world is coming to an end immediately after the pass, I believe rover stations would have a much more pleasant time handing out new grids. If you miss that desired grid today, doesn’t that leave opportunity for you to work it on another day? 73 Clayton W5PFG ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Twelve in EM12
OK, how about putting some teeth into it: 12 in EM12. That's 12 "satellites", though. Kinda like Amsat Field Day rules. With a few twists. RULE NUMBER 1: Contacts are only valid if they are between Amsat members. OR, if you really can't afford to join Amsat (no hard feelings, times are tough) but if you can certify (via Amsat receipt) that you have made a donation to Amsat at some time during the period of your contacts (i.e. between the first and last qualifying contacts). So put $5 or $10 (or more!) toward the AMSAT-NA ARISSat-1 and Fox fund if you can't afford a full membership. This is unashamedly intended to help increase membership and funding for these fine satellites, and future satellites. Other rules: Each modulation mode (e.g. CW, SSB, FM, SSTV, PSK-31, DV?) and each satellite mode (e.g. V/U, U/V, L/S) on a satellite count as a separate "satellite". You could conceivably do it in much fewer than 12 actual satellites. AO-7 SSB and CW on both Mode A (V/A) and Mode B (U/V) would be four contacts! One contact per mode per satellite means that you need to spread/challenge/increase your talents. FM voice on AO-51, SO-50, ISS (is the repeater working?) etc. won't do it all for you. FO-29, VO-52, ARISSat become important. And don't forget packet! MESSAGES through mailboxes like NO-44 (no beacons). Get out and exercise the birds and your capabilities! I'm sure there are enough satellite ops in EM12 to make it work. It likely won't be a one weekend effort, but that fact may stimulate longer term activity on the birds. This is a PROPOSAL though, to stimulate discussion and interest. If there is any, I am willing to process entries and send out awards, and hopefully there are other EM12s who would be interested in helping, too!

Well, it appears that the satellite did a reset just as it came in range here (EM12dl). My TLM start at MET 10, which was just after I heard the "strange noises" I hastily put in an email hoping that others might grab a listen. I have not witnessed a reset while monitoring, so perhaps that's what it sounds like. Some ticks, some strange telemetry tones, CW beacon underneath the tones, then the usual telemetry sound and data. So the reset would have been in full sunlight, not a good sign I would suppose. Unfortunately, the telemetry frame I was hearing right before the reset the bird was not in range long enough to have captured it all, or perhaps it quit in the middle of it anyway.

[amsat-bb] Re: ARISSat telemetry and Doppler tuning
I found it quite noticeable last night too, I'm 150 miles or so North of Ron's QTH. In my experience, the marker on ARISSatTLM was moving down rapidly as the satellite approached. After TCA (which was at about 68 degrees elevation, I believe) it reversed back to "normal". I was using the latest keps that I obtained from Space Track yesterday afternoon. I did find my PC clock to be off (ahead) by just less than one second, too. For what it's worth. My thoughts given what you all have written, would be that errors in all three (my location, my clock, and the keps) as Alan mentioned, probably contributed to it. On a typical linear satellite pass with a 2 meter downlink, I have never noticed it. I imagine that the effect is amplified in a perceptive sense, by sitting and watching the signal on a graph with pretty good resolution and not being distracted by copying the CW or working a voice QSO. 73, Jerry N0JY > Ron, > > Alan's points are spot on.

[amsat-bb] Re: Turn off AGC when receiving BPSK-1000
I have no option to turn off AGC with the FT-736R. I had been running on the Medium setting (my default) and have switched to Slow now. I'm not sure to say because it's rather subjective just watching, but I think it has slightly improved capture especially at AOS and LOS as well as when I have de-sensing due to my other VHF stations so rudely beaconing their APRS and WL2K info without regard to the science going on! ;-) Jerry N0JY On 8/17/2011 6:24 PM, Alan Cresswell wrote: Hi Mark, Phil, That's interesting. I have collected all my passes on the TS2000 with the AGC on and set to the longest setting. This is mainly because I often record the signal level every 0.5 seconds during a pass which requires the AGC to be on and the longest setting irons out any short fades. I will turn the AGC off and look at the statistics over a few passes but given that with the AGC on I get almost all the available frames I don't expect to see much difference. It will be interesting to see. 73 Alan ZL2BX __ Information from ESET NOD32 Antivirus, version of virus signature database 6386 (20110817) __ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: ARISSat-1 â telemetry top submitters
Thanks Mike and Roland, I was curious about the relative value that our telemetry had to the project (i.e. was there a deluge, not enough, just right). A question for all, for a few days now my ARISSatTLM has been reporting the Kursk as being (I believe, I'm not at home to check right now) something like Kursk-944.x or perhaps it was Kursk-444.x (some real low number compared to previous in my log) and it has not reported any new Kursk frames for the past 3 days or so at least on the ARISSatTLM display. I see from Mike's page that my Kursk to Telem ratio is lower than many. Is the Kursk data affected by the battery state, or is my ARISSatTLM perhaps hung up on that and needs a restart? Anyone else, what are the latest Kursk frames that you are seeing? Thanks and 73, Jerry N0JY > http://www.dk3wn.info/p/?p=22435 > > 73 de Roland PY4ZBZ > ___ > Sent via AMSAT-BB@amsat.org.

How about a checkbox setting in the application, or a command argument/switch, to have ARISSatTLM automatically START the sound card when the application is started?

Hi Mark, I'm using the speaker output so it's speaker audio with no additional filters, right to the Delta44 breakout box. SatPC32 does the doppler, it's set for 20Hz interval. Should I set that lower, to 10Hz perhaps? I am going to try to use the audio from the data output on the FT-736R. A brain fade on my part prevented me from getting the signal off the ring of the stereo connection, but I just woke up and remembered that I have the splitters for that so I've got that connected to the breakout box now! 73, Jerry On 8/6/2011 12:44 PM, Mark L.

I'm having trouble getting telemetry. ARISSatTLM will see the signal on the Tuning Indicator and I have tuned the CW signal everywhere from the yellow mark to the top and bottom of the blue range. It decodes the CW fine in the Morse Code Decoder window but nothing ever shows up in the Telemetry As Text or ARISSatTLM main window. The orange indicator is following something, usually hanging around the middle of the orange line range when there is a signal. Any thoughts?

[amsat-bb] Re: Bickering ...
I spent the last two days building and putting up a temporary NVIS antenna for 60 meters that I needed for a R.A.C.E.S. exercise that took place yesterday. I used insulated wire, hose clamps, two telescoping pool cleaning poles, 4 random sections of TV antenna mast, some PVC pipe, some wood, hose clamps, and cable ties. I whacked the poles into things while moving them, scraped some doors, smashed a finger, left cut cable ties all over the yard, twisted the wires, pulled down one end support trying to put up the other, lost cable ties, and slightly bent a small bit of my backyard fence. If I had been on TV while doing this and I had to undergo the same scrutiny given the ARISSat launch by some in this crowd, I would no doubt be considered to be the clumsiest person on earth with no idea what I was doing and no clue how to do it. But you would not have been there in the 108 degree heat, to appreciate the amount of effort necessary to get this done by one person in a short period of time, with limited resources. And the antenna worked well, and accomplished its mission. So has ARISSat. If you didn't put it together and you didn't launch it... don't tell those who did, how they should have done it. Thank you. It's good to see those here who are focusing their energy on the rewards and celebrating the success, rather than complaining about the perceived mishandling (a.k.a. backseat driving). I watched the launch while we were doing our exercise, and I can't wait to get my opportunity to hear and work ARISSat this weekend when I'm not stuck at work!!!

[amsat-bb] ARISSatTLM
I downloaded ARISSatTLM and in the Quick Start guide I notice that it says Windows Vista not working on this platform at this time Not being deterred I loaded and ran it anyway and it did choke when trying to start the sound card, with a Windows "stopped working" type of dialog. I found that if I quickly click CANCEL on that dialog, things seem to work fine. The tuning shows indications of signal that were verified by playing with the input level and tuning a CW signal (on HF) which ARISSatTLM decoded. I run two sound cards, one being the built in which I use for the typical Windows stuff and sounds and games and then an M-Audio Delta 44 which is for the radio input/output for sound card modes. I don't know if that has anything to do with the way this works. So I thought I would share that with you, if you are running Vista you may be able to run ARISSatTLM despite the disclaimer. If anyone knows where to find a .wav file of the latest data sizes for the satellite that I could run on ARISSatTLM, please let me know so that I might verify that the telemetry decode works too. I found some on the development web site but I think they're old and of a different dataset size. Anyway they didn't work. 73, Jerry NØJY ___ Sent via AMSAT-BB@amsat.org.

OK my brain may be playing tricks, but if you vary only your transmit frequency such that you always hear yourself on the same downlink frequency, isn't it true that the other station may not necessarily be hearing you on the same downlink frequency and is chasing you anyway? Your doppler is +5kHz (for example) on the receive, the bird is just about to pass overhead of me though so my receive ferquency goes rapidly from +2kHz to -5kHz, your transmit tuning has no relation at all to what frequency I am listening on. Then the bird goes past you and you suddenly switch down 5kHz, so I have to follow you on my receive. Or am I nuts? (Quite possible, come see where I work and you will understand!)

[amsat-bb] Re: Diplexer
Mike, I have used such a setup for some time now, I have a 2m/70cm diplexer at my desk and one at the antennas, so that I can use one feed line (LMR-600). I also switch the heck out of the feeds with several coax relays in order to achieve different satellite modes as well as put the radios on my terrestrial vertical. I acquired the relays and diplexers over the years at hamfests and online auctions, I think I bought a diplexer or two new also. The article you may be referring to was in the May 2010 QST, by Steve Ford WB8IMY. If you don't have that QST issue, you can view it online at ARRL if you are a Diamond Club member. You can see a few pictures on the Satellite Antennas page of my website, http://n0jy.org. On that page there is also a link to a PowerPoint presentation of the whole antenna switching scheme. That will show you a bit about the use of the diplexers. My experience in using this setup has been positive, I have no empirical data about signal loss or comparisons to what it was like before I went to one feedline. The cables prior to the switch were RG-8 and Belden 9913 anyway, so comparing to LMR-600 wouldn't be apples to apples. It just works good. I've had no problems with signal strength both up and down, and make all of the contacts I wish to. 73, Jerry NØJY On 4/8/2011 8:59 PM, N8GBU wrote: > I was wondering if anyone has scene the article about using a diplexer (I > think that's the right name) on both ends for a satellite setup?
