[amsat-bb] volunteering
Hi After reading various posts I decided that having time one my hands at the moment, I would like to volunteer to help out in whatever capacity I can. I think being able to help build a satellite is probably out of my league. But I could help out collating information and updating websites etc. I run my own web server built by myself and a few websites. Hopefully someone can contact me for a discussion on how I can help.

[amsat-bb] Re: ITAR is interesting to me
Gretting to the list I wish to thank everyone that took part in the discussion of ITAR as it pertains to Amateur Satellites. I have learned many things. I am sure others may have also. It is obvious that Amateur Radio before satellites had few if any ITAR problems. Now we have a very specific ITAR path to travel with any Amateur satellite. I submit that the AMSAT BOD is doing a good job for the membership on this ITAR issue There were a question or two dealing with security as it related to indiduals that were working on ITAR compontents or the AMSAT facility itself. At least it seemed to be a stretch for anyone to discuss that issue. There are those like AMSAT that have a almost impossible time dealing with ITAR There are many more that have to do business or engineering work where talking to anyone becomes a probems I never had to concern myself with ITAR and that is the reason I needed to learn more about ITAR. I can assure all that there is another side to ITAR when the rules are not followed and that is the side I worked for on for 37 years. Think of all the testing that must take place when information is lost when the ITAR rules are not followed. No offense to any of my Amateur friends that have hard feeling because of ITAR, I understand. But like always there is always two side to any story.

[amsat-bb] Re: Filters and Preamps Question
Thanks for all the great responses. I'll try switching them around and see how it affects performance. Although I'm in Kansas City, RF pollution is not too bad at my particular location. One benefit of the filters is reduction of desensing the receiver when xmitting, especially with preamps on. 73, Elan WB2IOL ___ Sent via amsat...@amsat.org.

LOL You missed my point entirely. The Amsat people who build the satellites mostly don't have time to read Amsat-BB, so the thickness of their skin is not the issue here. But Amsat-BB is not read only by Amsat members. Anyone who Google's "Amsat" will find Amsat-BB very quickly. Negative and unprofessional comments on Amsat-BB hurt our image as professional satellite builders and could quite possibly kill our chance of finding our next ride to orbit. In the 1990's the ESA management handed the president of Amsat-DL a pile of e-mail printouts from Amsat-BB following the repeated launch delays on Phase 3D, it almost got the satellite thrown off the Ariane 5 vehicle. With launches even harder to find in today's world, we cannot allow such bickering to tarnish our image as professionals who can be trusted not to screw up the mission.

We had grid dxpeditions on the east and west coast, two hamfest demonstrations, the Boy Scout Jamboree stations and an Alaska Statehood special event station operating. Patrick, WD9EWK, was at the Old Pueblo Radio Club Hamfest in Tucson and made a big detour to continue down I-10 to the Arizona/New Mexico state line where he operated from in the afternoon. Doug, KD8CAO, was at the Holland Michigan Lakeshore Super Swap Hamfest and put on a demonstration there. Mark WA8SME operated on one AO-27 pass from the DN00/DN01 grid boundary, two very rare Nevada grids. John W6ZKH operated from DM07 but had some trouble with his equipment on this particular pass. He said he will go back some day. Mark also said he might be able to operate from DM07 in the near future. Then we had the Boy Scouts Jamboree on the Air with quite a few different stations operating on all of the FM birds including K2BSA/5, W0S, K5B etc. The most prominent grid dxpedition this weekend was by Richard, N2SPI. He had originally planned to operate from FN53, FN56, FN57, FN66 and FN67 but he found a way to also operate from FN55 and FN65 as well. He worked on the FM birds as well as VO-52. This operation began Saturday morning and finished up Sunday afternoon, about 30 hours from the first qso until the last on AO-27 at 1853z. Richard operated at least one pass in each of seven grids and never operated on a grid boundary. This was quite a trip! Richard returned back to Massachusetts late Sunday night. The weekend rounded out with an announcement to look for KL5O, an Alaska Special Event Station, on the birds. The AO-7 pass Sunday evening at 0043Z had at least 14 different stations operating including WV9E, KE5GFJ, WA4NVM, AA4FL, AA5PK, K6CDW, KE2CKO, K0OU, K3SZH, AJ9K, KD8CAO, W7LRD, K8YSE and KL5O! KL5O was down around 937 late in the pass. So if you think that there is no one on AO-7, this should put that thought to rest. Many of them were talking about KL5O. A special event does draw people to the birds just like it does on the HF bands. Of course working Alaska is a special treat under any situation. I believe KL7XJ was the operator. Activity is on the rise on the SSB birds in general. Many that have been active on the FM birds are getting equipment set up for the SSB/CW birds. It's nice to be able to have a qso that involves more than a callsign and grid exchange. We hope to have FO-29 back soon but VO-52 and AO-7 are there for us every day. A big thanks to all of the grid dxpeditioners who spent a lot of time and money operating from places away from their homes. They have given us many new grids. I hope this encourages others to try their hand at operating from other grids. It's a lot of work but you will have a lot of fun and satisfaction doing it. 73, John K8YSE John Papay j...@papays.com ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

In this configuration we have --> antenna --->a T/R coax relay> preamplifier >cavity filter all antenna mounted and a coax cable connected to the output of the preamplifier devoted only to receive and directly going down the shack -->to the receiver. In more details the antenna is connected to the common port of the T/R coax relay while the preamplifier is connected to the normally closed NC contact of the T/R relay In order to transmit the TX power amplifier is connected directly to another coax cable dedicated only to transmit and it is connected at the antenna via the normally open NO contact of the T/R relay. The above configuration using a filter at the output of a preamplifier is the best one because it do not degrade the preamplifier Noise Figure but reduces the bandwidth providing a bonus in selectivity. It is possible to improve the above configuration introducing between the antenna and input of the preamplifier a filter plus a preamplifier protection device designed by K3PGP showing a very low insertion loss less than 0.1 dB at 432 MHz that without to deteriorate the preamplifier Noise Figure provides in addition another bonus of selectivity at the preamplifier input as you can realize reading the following page: http://www.k3pgp.org/432filter.htm >From 1977 I was a 432 MHz EME operator so that I actually use for satellite the above discussed setup both for 2 meters and 70 cm because I live in the center of the gulf on Naples with a terrific RF pollution in every amateur and out of amateur band so that a filter at the preamplifier input and output is also mandatory to reduce the preamplifiers gain compression due of out of band strong nearby signals. It is evident that using a filter at the output of a preamplifier it becames a complicated matter using a commercial preamplifier with two coax relays into it and by using only one transmission line to receive and to transmit because the preamplifier output filter must be a big one to pass all the transmitter power and particularly it must be tuned in such a way as not to introduce a high VSWR into the TX transmission line.

[amsat-bb] Filters and Preamps Question
On both 70cm and 2 meter antennas, I have DCI filters tuned to sat passbands as well as ARR preamps. My question is: what's the preferred order? Presently, I have the filters closer to the antennas, with the assumption I'd be better off supressing spurs first, thus preventing them from hitting preamps and desensing. Any thoughts? ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

[amsat-bb] Re: THE DMSP launch
Robert WB5MZO > Are the people who are suppose to be the experts in building state of the art > satellites so thin skinned that a bulletin board > slows their progress? LOL I want to remind you each and every time you write a message: AMSAT is a volunteer run group of space-craft experimenters sharing a hobby and a purpose: Ham Radio & Education. As you should know there is only one paid employee of AMSAT at the headquarters and everyone else is just a member. With regard to the skill and qualification of the "experts" you refer to in your e-mail, perhaps you have seem to have the expertise of being a cynic and a critic - in addition to being right on everything you say, according to yourself - meanwhile, others are lending their varied expertise in the areas they feel most comfortable electrical, mechanical, thermodynamics, Solar PV etc. etc. and in certain cases, actual donations to fund further R&D at their own cost. I am not sure where you have found any documentation from AMSAT-NA that we have any portion of capability or indeed requirement to build "state of the art satellites". All the bits of stuff that have been incorporated into satellites so far are probably best described as hobby kits or more exactly waste material from other projects. Are you faulting AMSAT members for wanting to work for $0.00 and pursuing a dream of being creative - and to have chance to tell their children, look I built that and it is in Space ? Are you criticizing the current activity and past activity and anything that they may come up with in the future because, according to you, these AMSAT "experts" don't have the right stuff ? Or are you just trying to get noticed ? Ok then, assuming you want the spotlight and are correct in your conviction that you know what you are doing, what is your recommendation for steps going forward ? Put your thinking cap on instead of and submit a development plan that will use the annual dues from about 1900 paying members and organize a working group amongst your friends in the amsat community -- and build -- a satellite -- and launch it into space. Or, you could start a campaign to get votes from the members to become the next President of AMSAT-NA... coming up soon. BTW, you can write off your donation to AMSAT on your taxes, but then you already knew that. Looking forward to reading about your development plans soon.

[amsat-bb] Re: ITAR is interesting to me
Bob, Bruce et. al.,
This is probably a very reasonable thread of discussion to follow,
compared to other snippy comments/jibes/frivolous remarks that I have
seen on amsat-bb recently. I have started up a separate private thread
to allow us to discuss a managed bulletin board to supplement the open
mailing list to accomodate:
+ potential need to have a closed community of registered members
discussing itar-covered topics
+ a searchable archive of topics, posts that users can leave in the
archive on a permanent basis and stop repeating ad nauseum
+ optional open-forums and closed-forums depending upon the
affiliation of a particular member. An example of this is the IEEE,
which as an organization provides the IEEE scanner publication to all,
but only the referred journals/publications to members who are part of
a particular society. So, if you not a member of the AESS society,
you won't get the AESS Journal, but you may become a member (of your
choice) of any society that you wish. In my analog, amsat-bb will and
should be open for general users not involved in satops, satengg,
mission planning, but only using it as a hobby. Separately, if there
was an amsat-engineering or some other forum should in my opinion only
be open to those that have agreed to sign a volunteering agreement
with AMSAT agreeing to comply with a written policy, that is inclusive
of the ITAR regs for "U.S. Persons".
+ The key issue of course is that in the U.S.A, we must be in
compliance with all laws, and those "Federal" laws trump individual
association/non-profit laws that one may think of.
That said, I would like to submit to the amsat-bod through amsat-bb
(Hey, I don't have access, I am a newbie!)
Have you looked at:
http://www.research.ucla.edu/researchpol/memos/Memo_Ofac.htm and
considered the implications of adopting a restatement of our bye-laws
to reflect our current role as a fundamental research institution in
amateur space systems and potentially amateur rocketry as well ?
I urge all to review THIRD (A, B, F, G) once again from
http://www.amsat.org/amsat-new/AboutAmsat/documents/bylaws.php
But more importantly, Bob, or any other competent amsat member, we
must spend the time to read ourselves thoroughly
http://edocket.access.gpo.gov/cfr_2002/aprqtr/22cfr121.1.htm that
might offer the chance to request a WAIVER. The reason for this would
be based upon the following question:
Why should AMSAT Satellites with clearly defined specifications be
considered as SME (Significant Military Equipment) given that they
follow ARRL/IARU/ITU spec for frequency, and their systems are
composed of all non-military sourced components ? If there is an
opportunity to expand on this in a formal working group for AMSAT,
sign me up please !
I am not minimizing the effect of ITAR regs on foreign co-operation,
those will obviously have to be developed under a restricted TAA (Tech
Asst. Agreement) but perhaps this would be good in a way as it would
force AMSAT-NA to focus on increasing membership of domestic U.S.
persons and build satellites that are designed using local talent
(implying educating U.S. youth using mature workforce). Also, ITAR now
implies unrestricted publication of data/articles for ITAR covered
subjects are also restricted, even for a TAA:

We need a technical assistance agreement with our Canadian brethren in amateur satellite service work. The tough part for this is that we really need to work out the technical assistance agreement with an umbrella organization for our Canadian colleagues to be legal or be granted a specific exemption or work out the agreements with individuals. Since Canadians are members of AMSAT-NA what organization could easily serve this role? What individual would do this on their own without an umbrella group over them? You have to agree to go to a federal prison or pay a ridiculous fine if you violate this as an individual. Who would expose themselves to this? If I sound overly negative about ITAR that is simple. I am truly negative about its application to amateur radio satellites with an open door and publication policy on what we are doing in a not-for-profit mode as a 501c3 educational organization. If I were to work on a DOD satellite, I would expect to keep my mouth shut or go to prison. I have no trouble at all distinguishing the difference. ITAR and the amateur radio and amateur satellite services are confounded in paranoia built in a time when the Soviet Union existed and thank goodness those days are over. But what has resulted is a new set of boogie men to take their place and it being even harder to see how amateur radio satellites contribute to their evil insidious plots against us! I am unconvinced that even trying to stop commercial companies from discussing the technology used in their satellites for non-defense purposes serves a serious security need for the U.S. since I believe all of the serious potential adversaries on our radar have developed rockets, spacecraft, weaponized warheads on the rockets, and more and ITAR did NOTHING to prevent it except for a delaying action that allowed the potential adversaries to build their own independent means but for these purposes, getting the shackles off the ankles of amateur radio, I don't care about this argument. My primary argument is that it makes absolutely no sense to stop AMSAT-NA, AMSAT-UK, and AMSAT-DL and AMSAT-ZL and AMSAT-VK . from talking things over to make rational decisions. More than one of these entities just mentioned is trapped in a dilemma for their programs posed by ITAR because we cannot help them without an onerous agreement they are unwilling to sign up to.

I know a tale. I will NOT attest to its veracity since I was not there but I believe it. Somewhere in the world associated with space and military we allowed (a) foreign national(s) to use our facilities to monitor one of their launches as they needed a world wide network for it and we were playing nice. One of their nationals asked "May we put an antenna on that tower and cover this location for our hand held communications for coordination of our activities". The question was answered. The company that employed the person answering the question was fined in excess of $100,000 for answering the question as an ITAR violation because they aided the ground station support for the launch and that was a DEEMED export and not an approved one. I was once told that it is simply impossible to follow ITAR to the letter and achieve any purpose. What you do is negotiate a document of exceptions and reporting and call it a technical assistance agreement. Once that is approved you are allowed to communicate but heaven help you even if you inadvertently exceed the authority of that document. I just cannot afford personally to take such risks especially after making a full mea culpa on those things which were done wrong before and being told "do not do this again or it will be tougher". > I infer from previous comments on this list that ITAR also prevents detailed > discussion of an amateur satellite via an email list that is open to non-US > citizens and might also impact on a Wiki or articles written by US Nationals > in publications such as the AMSAT Journal. > > 73 Trevor M5AKA > > > One can only hope there is some sanity turned on amateur radio spacecraft in particular some day since we are not-for-profit and have education and international comity as our goals.

Germans are by their nature (from my experience) rule abiding law followers and do not want to sign documents exposing themselves to onerous restrictions. So far as I know, they do not force foreign citizens (non-Germans) to sign a document that says for the purposes of the satellite exercise, it doesn't matter where in the world you are, or even if it is illegal for you to sign such a document in your own country, you will agree you are subject to German law. The chutzpah involved in such a set of rules on our part is almost too much to wrap your mind around, especially applied to amateur radio satellites since these rules interfere with the purpose of amateur radio world wide. > 11.)

[amsat-bb] Re: ITAR is interesting to me
Thank-you, Daniel for this helpful reply. Your 'diode' analogy was excellent. Using the links provided by Samudra above, I was able to find some parts of ITAR that exempt Canada. Specifically, 126.5(b), which in turn has restrictions on *it* in the following passages. One of these restrictions is on "all spacecraft in category XV(a) except commercial satellites". This is a bit frustrating, since it seems likely that the regulation means by 'commercial satellites' 'satellites with no national security implications'; but for we amateurs, if we read the letter of the law, 'commercial' excludes us as an apparent side-effect. I fully admit that I might have misunderstood the regulations, since they are, quite appropriately, written in a particular sub-dialect of legal language. Obviously any speculation on this list is no substitution for the professional opinion of a lawyer. Finally, let me say that I really appreciate the board tackling this issue so directly. It must seem pretty tangential to the corp's larger project, and I know if I were in their shoes I'd find it rather frustrating work. 73, Bruce VE9QRP On Mon, Oct 19, 2009 at 1:11 AM, Daniel Kekez wrote: > Bruce Robertson wrote: >> Given that AMSAT-NA is by definition a collaboration between amateurs >> on both sides of the US/Canada border, do we have a clear idea where >> ITAR stands with respect to Canadian collaborators?

Hi guys thanks for responding and i fully understand whats involvedbut from a sat opp point of view it would be nice if we could manage one bird like a07 ...that is its hight? and transponder ever 25 years? or so...?? and not have to rely on 25 year old tech...that works and works well...im a big beleaver ...keep it simple it works and lasts Thanks for all ur hard work and im sure im not alone in saying keep up the good work and lets hope a ride comes along to for fill our needs..so we can keep this great part of the hobby on going! de paul ..raining in scotland ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: ITAR is interesting to me
As was commented earlier ITAR certainly does makes it tricky when try to sell something to an American customer who isn't allowed to tell you what they want. Am I right in thinking the penalty for a US citizen who incorrectly interprets ITAR and inadvertantly breaches it can be a 4 figure fine or jail term ? I infer from previous comments on this list that ITAR also prevents detailed discussion of an amateur satellite via an email list that is open to non-US citizens and might also impact on a Wiki or articles written by US Nationals in publications such as the AMSAT Journal. 73 Trevor M5AKA ___ Sent via amsat...@amsat.org.
