ARISSat-1 over West Malaysia 12 Aug 2325 UTC
by Sion Chow Q. C. (9W2QC) 12 Aug '11

12 Aug '11

Dear All, ARISSat-1 over West Malaysia, 12 Aug at 2325 UTC: 1. Satellite was in high power mode 2. FM downlink was heard very clearly 3. Managed to capture and forward 24 telemetry on the BPSK1000 downlink which was strong Based on telemetry from CW decoder (unfortunately I had my telemetry window in ARISSatTLM software accidentally closed): MET - 9 min IHU Temp - 31C Control Panel Temp - 23C Batt Voltage - 35.90v Batt Current - -8mA However, battery was observed charging later on during the pass. I hope that all will go well for ARISSat-1. 73, Sion Chow Q. C., 9M2CQC Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

ARISSat-1 HEARD over West Malaysia 12 Aug 2151 UTC
by Sion Chow Q. C. (9W2QC) 12 Aug '11

12 Aug '11

Dear All, After seeing so many NOT heard reports, I am pleased to inform that I heard ARISSat-1 as below: 12 August, 2151 Hours, all time UTC or 13 August, 0551 Hours, MYT Maximum elevation: 3 degrees FM Voice Telemetry: Battery Voltage 35.66v Battery Current (unfortunately there seems to be no +ve or -ve announcement) 34 mA It seems like ARISSat-1 is in low power mode but I might be wrong, as I cant differentiate low power and emergency mode. I have a 57 degrees pass in 1 hrs 20 miutes from now and will try to listen out for FM and BPSK telemetry. 73, Sion Chow Q. C., 9M2CQC, Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

Re: ARISSat-1 battery eclipse voltage decreasing
by PA3GUO 12 Aug '11

12 Aug '11

Dear Gould / ARISSat-1 team, Thanks for sharing this ! When the battery would go dead (or has very long charge times), to what extend would that also impact the low power mode ? Better phrazed: what are the requirements to go/stay in low power mode ? Is there a (no power) mode, where there is not enough power to go even into low power mode ? A kind of test/emergency mode, where the uplink/xponder and even FM is off but only the CW beacon is still on ? ... another question: Which type of command capabilities are available to the team, only a bare minimum (satellite TX on/off) or more ? Best regards, Henk, PA3GUO > The ARISSat-1 Battery voltage is decreasing each eclipse period. It therefore is taking longer for the Battery to charge up to 32.5V to allow the switch from Low Power to High Power when the satellite enters an illumination period.

Tuning Uplink
by Paul Delaney - K6HR 12 Aug '11

12 Aug '11

When I transmit to a satellite I do not hear myself on the downlink. I've read that tuning with the +/- keys in SatPC32 should bring my signal into the downlink. How far off center could these numbers be before I would hear myself? I am tuning to +/- 3000 or so and hear nothing even on very high passes. Any hints or tips would be greatly appreciated!

Future passes
by Dee 12 Aug '11

12 Aug '11

I just did a quick crystal ball analysis and for September, the passes over the US will be more toward normal school hours and we should have more participation of classrooms that are adding this to any courses etc. Presently, there are only a few diehards staying up past bedtime to listen to ARRISat-1. I don't think classroom activity will ramp up until the daytime passes begin. Keep up the publicity. Keep forwarding the important telemetry data to the team. (see upcoming ANS-226 this weekend.)

My call is KA8WWK. I am in Barberton, OH. I heard ARISSat at 2130 hours EST 08/11/11 and 1239 EST 08/12/11 on 145.950 MHz. The radio is a KLM Multi-2700 in FM mode. The antenna is a Cushcraft ARX-250B dual band ringo mounted on my chimney. I can also hear the sat on my HTX-202 handheld with the antenna at an angle to the ground during those times as well. I also was able to receive it in my car using a 1/4 wave vertical trunk mounted using a Yaesu FT-2500M 2M radio!!!! 73's Paul KA8WWK www.myhamshack.com/ka8wwk

Tony, I have SatPC32 running perfectly on my MSI U130 netbook – 2GB RAM Windows 7 – driving my IC910H. Digital stuff like Fldigi and MMSSTV work just fine and it has all the guts needed to drive my Signalhound spectrum analyser and MiniVNA Pro using the inbuilt Bluetooth. I haven't tried it with HRD, mainly because the Sat Tracker still doesn't work with the Icom IC910H. The MSI packs a lot of punch in a small package. Cheers, Alex VK5ALX

The satellite was carried into space by a Long March-3B rocket from Xichang Satellite Launch Center in Sichuan province late on Thursday night. PakSat-1R was built by scientists and engineers from Pakistan's Space and Upper Atmosphere Research Commission with technical guidance and financial aid from China National Space Administration. The launch was witnessed by a group of Pakistani officials, including Strategic Plans Division chief Lt Gen (retired) Khalid Ahmed Kidwai, Foreign Secretary Salman Bashir, Pakistan's Ambassador to China Masood Khan and SUPARCO chief Maj Gen Ahmed Bilal. The satellite carries a communication payload to facilitate the launch of a several new services, including broadband Internet, digital television broadcasts, remote and rural telephony, emergency communications, tele-education and tele-medicine. PakSat-1R is expected to have a lifespan of 15 years and will be operated from SUPARCO’s satellite ground stations in Lahore and Karachi.

Hi Folks, My first post to the BB website. I'm new to the Sat world and trying to find the suitable radio here. Can someone tell me if the TS 2000 will put DC voltage down the coax to trigger the pre-amp? I'm also considering an Icom 910H if I could find one. 73 and thank you Joe KT7E

Hi Joe ! Welcome to this group and the exciting world of satellites ! No, the TS2000 can not put DC voltage on the coax for pre-amps. We have often a discussion on which radio is best, which is always interesting. Others (not me) will be able to provide better inputs on that. Again: welcome and have fun !

First SSTV transmission via the ARISSat-1 transponder !

11 Aug '11

Today morning at 02:58utc I succesfully did a short SSTV test using the linear transponder of ARISSat-1: http://www.pa3guo.com/pa3guo_arissat1_sstv_9aug2011_0258utc.jpg Prior to this I did some experiments with CW, starting at 50W, going down to 5W. My TS2000 does not go lower as 5W, but I believe even 1W or lower will be audible. In my opinion the transponder uplink is VERY sensitive. Using the FunCubeController SDR is it nice to see the full downlink spectrum, on the left the CW+BPSK signals, the transponder downlink in the middle, and the FM downlink on the right. Equipment: Uplink HW: TS2000X, 435MHz, 5W RF power + 12 elements beam Uplink SW: MMSSTV + HRD (doppler control) Downlink HW: FunCubeDongle (SDR) + SP-2000 preamp + 2x6 elements beam Downlink SW: MMSSTV + DK3WN Satcontrol (doppler/freq control) + HDSDR (SDR) -- Henk, PA3GUO, The Netherlands

Any ARISSat-1 news/updates from the project team ?
by PA3GUO 11 Aug '11

11 Aug '11

Just a kind request to the ARISSat-1 team, Via this amsat-bb a lot of early feedback is provided on the satellite. Often new satellites fail shortly after launch, so it is key to collect as much a possible data in these early days. Many people do this already. However, we also have many questions and report observations, (as an example the high/low power mode switching over VK) without any reply from the project team directly. Btw I have to say that on BPSK topics Phil Karn & Douglas Quagliana are really doing a great job in discussing the results and giving feedback (thanks guys - very learnful !). IMHO way to much information is still not made available, or scattered around on various websites, sometimes even in articles of magazines ... Last Twitter post (tweet) was on Aug 3. Last News post to www.arissat1.org was on Aug 5. As an example: I still have no clue on the operational mode switching sequences, like voice... sstv, but also: when will which type of BPSK be transmitted, how long are the transmission sequences, what is the TX off-period. Please don't take this as an offend, I know we are all very busy. But really, if we want to interest new people - we have to step up and provide more and better information about the mission which was announced so widely. >From a technical point of view the project seems like a big success; the SDX is working just fine, and we have with a broken (?) antenna still a great uplink capability. Let's celebrate this success and further exploit the momentum that we have now. Would be a nice start to have a daily summary of which parts of the system have been tested, are working, etc. etc. Of course, let me know if I can be of any help !

Re: ID of hardware in the SSTV
by Burns Fisher 11 Aug '11

Larry and Mike: Thanks for the info. I had forgotten about the call sign color indicating the camera. My "my mystery object" is always in the GREEN (+Z) view, so it is clearly on the spacecraft, and as Mike says, I suppose that is likely the 2M antenna. The shape is what confused me...it appears to be flat with a kink on the end, which is not what it looks like from pre-launch pictures. But this is a different angle too. The other thing that led me astray was that some other photos had a straight line in them which I took to be the 2M. See for example http://www.amsat.org/amsat/ariss/SSTV/uploads/3376.jpg. However, now that I remember the color key, I can see that it does not appear in every view from the same camera, and in fact there are similar artifacts even in a few +Z views. So it must be something external; maybe some artifact due to glare (it always seems bright). Anyway, thanks. This is really cool stuff!

ARISSat TLM decoding using FCD
by PA3GUO 10 Aug '11

10 Aug '11

Just sharing the results of my recordings of last night: (using the FCD + HDSDR) - FM voice works fine - Xponder works fine (HB9AOB was very clear) - CW decoding works fine (the Tuning indicator locks on the CW bump) - BPSK decoding did not work (I hear & see the signal, but no decode) Is the BPSK decoding very sensitive to doppler / freq hops ?

CM79 - Another chance Saturday August 13th with SCRA/N6T
by David Palmer KB5WIA 10 Aug '11

10 Aug '11

Hi Everyone, In case you missed me at CM79 this last weekend, the Sonoma County Radio Amateurs are going to be there this coming weekend August 12-14th. Charlie KZ6T reports that they'll be active on HF, 2m, 6m, but also will try for a few satelllite passes on Saturday August 13th signing as call N6T. This is the list from Charlie, all times local: AO-27 11:54(L) 65 degree pass AO-27 1336(L) 14 degree pass SO-50 15:42 (L) 57 degree pass AO-51 16:51 (L) 10 degree pass AO-51 18:25 (L) 75 degree pass (occurs after break down time) http://scranews.wordpress.com/2011/06/09/scra-sponsoring-mini-dxpedition-to… I certainly wish them luck!!!! Maybe I'll get to put CM79 in my own logs this time! 73 de Dave KB5WIA

ID of hardware in the SSTV?
by Burns Fisher 10 Aug '11

10 Aug '11

Hi, There appear to be two different TV camera views that have some parts of ARISSat-1 visible in them. I would guess that one is the 2m antenna, but the other one appears to be thin and wide with a crook on the end. Almost like looking out an airplane window at the wing. Can anyone ID that piece? I've been looking at pictures, but can't seem to find anything that looks similar. (Or might this picture have been taken before deployment and have some little element of the ISS?) Thanks, Burns, W2BFJ

High Performance Low Cost Scratch Built Rotor for Portable or Indoor Use
by Thomas Doyle 10 Aug '11

10 Aug '11

For many months I have been working on the design of a scratch built (no TV rotor conversion) rotor and it is now operational. The goals for the rotor project were - rugged robust construction, very accurate, low cost, relatively easy to construct, fast, no gear train, no brake, strong enough to handle a pair of small beam antennas such as the Elk 2M/440L5 and 440L8 (Arrow antennas would probably work but I do not have any), run off 12V DC, small, light, at least 450 degree rotation, easy to control the heading, and easy to set up and take down for portable or indoor operation. Things that are not included - the ability to handle large antenna arrays and weatherproofing. The rotor meets all the design goals. In the video the antenna turns through 450 degrees in 19 seconds. You can check the accuracy by looking at the alignment of the front element of the 70cm antenna with the left side of the window blinds on the back wall at the start of the video. After rotating 450 degrees left and then 450 degrees right it is right back where it started. It is very cool or at least I think so. One item finally completed on my bucket list. The video is HD and looks great full screen. Perhaps only a ham would think it looks great. http://www.youtube.com/watch?v=JPhavWyShMo The controller is exactly the same as used in the iPoint project. http://www.youtube.com/watch?v=gnc4-XcEXEQ 73 W9KE tom ... P.S. I am not trying to sell anything.

KB5WIA CM79+ Expedition Trip Report
by David Palmer KB5WIA 10 Aug '11

10 Aug '11

Hi Everyone, Well, I'm back from the CM79/CM89/CN70/CN80 grid expedition. It was quite an adventure! Operating ham radio from the CM79 corner certianly is difficult -- but it was really rewarding to actually make contacts from up there. I made a total of four trips up and down the mountain, hiking over 20 miles with almost 5000 feet of climbing. Thanks to everyone who was trying to contact me, and for your patience dealing with my weak signals!! I've put a full writeup with photos and video on my website at: http://kb5wia.blogspot.com And if you want the short version and just want to see the operating conditions, you can watch the video tour: http://www.youtube.com/watch?v=ef5_cYzwIZo Briefly: I was able to stick fully to the plan -- and operate exclusivley from the actual intersection of the four grids down the hill from the ridge, using the remote antenna for the low eastern passes. The weather on the trip was great -- good temperatures, little wind, and sunny. The actual area of the grid intersection is heavily forested, and that really soaked up the UHF downlink signals from the sats! I didn't see any ticks, rattlesnakes, bears, nor mountain lions -- but did see plenty of mosquitoes so I was glad to have a full can of DEET. Solar power worked well. Operating from the exact grid intersection wasn't easy, at first I thought it might be impossible, but over time I figured out ways to make it work. I was very fortunate not to have any equipment failures or other disasters! Thanks also to everyone who provided advice before the trip, especially Bill Moore at ARRL HQ and Russ KB8U for tips about the area. See my full writeup for all the details and pictures. As usual, no need to send me a QSL card if you've already sent me one before -- just send me an email with the contact details and if you're in the logs I'll send you a card back. 73 de Dave KB5WIA

Student Sat for Geostationary ?
by Trevor . 10 Aug '11

Strange one this, story appears to indicate that a student satellite from the Sharif University will go into a 36,000 km orbit. http://news.xinhuanet.com/english2010/sci/2011-08/09/c_131036680.htm Their domestic launch capability might appear at best to be 500km, Rasad-1 was 260 km ( pic of 465 MHz downlink at http://www.r00t.cz/Sats/Rasad ). Might imply an overseas launch or else something got lost in translation. http://www.iranmilitaryforum.net/index.php?topic=9758.0 73 Trevor M5AKA

Sample ARISSat-1 recording with Funcube Dongle using HDSDR
by Mark L. Hammond 10 Aug '11

10 Aug '11

Hi All, I've been recording quite a few passes of ARISSat-1 using the Funcube Dongle (FCD) SDR and the HDSDR program. The resulting file from a 10 min pass, recording the whole FCD passband, is about 250MB. Below is a link to a sample from this morning. The bird was in the sun, so it's transmitting continually, making things easier. This sample isn't perfect, but it's pretty good. It was made using my "low" array, which is a M2 2MCP14 configured for RHCP. There is a good ARR preamp at the antenna. When in the clear, it's quite good--but much of the pass is through the house and/or trees.... You can play it back using HDSDR (google it). If you've never played with SDR, you have some reading to do :) This isn't a "How To" but rather a "here it is if you want it." (The imminence of another academic year prevents me from doing a write-up with instructions...sorry.) The recording was made with NO correction for Doppler. About a minute into the recording (click to fast forward, back up, etc...it's slick) you'll see signals--CW telemetry, the BPSK telemetry, the linear transponder, and the FM voice channel. Move around, change modes, listen, etc. Back up at will, just with a click. If the bug really bites you, you can install Virtual Audio Cable (VAC) and have HDSDR use it as the output, and then configure a decoding program (like ARISSatTLM or MMSSTV) to decode telemetry and/or SSTV pics using VAC as the input. It's neat. You can print SSTV without tuning for Doppler on playback. That's not the case for the BPSK telemetry! The file is BIG, nearly 250MB... https://docs.google.com/leaf?id=0B9vJkMVYq-VOYjM5NTNiZDYtODMyMS00NjE4LTlhYW… Have at it :) Mark L. Hammond [N8MH]

Re: Mirage preamps
by Sebastian, W4AS 10 Aug '11

10 Aug '11

My thanks to everyone who has responded. 4 out of 4 say it's ok to use the 847 to power the preamp. I put up the 432 one today, but with the KP2 control box, just in case. But I will go ahead and remove the box, and let the 847 power it. One interesting response was to be careful if there is anything inline between the rig and preamp. Lightning protection, or even an SWR power meter, could affect the sending of voltage. 73 de Sebastian, W4AS On Aug 9, 2011, at 3:16 PM, Lowell White wrote: > Hi Sebastian, > > I'll be interested in knowing that also... thanks for asking. > I also have an FT-847 in my stable and have the KP2/2m on my "soon to acquire" > list. > > 73, > > Lowell > K9LDW > > > ------ Original Message ------ > Received: Tue, 09 Aug 2011 11:34:22 AM CDT > From: "Sebastian, W4AS" <w4as(a)bellsouth.net> > To: AMSAT-BB <amsat-bb(a)amsat.org> > Subject: [amsat-bb] Mirage preamps > >> Before I destroy these, is anyone using Mirage KP-2 mast mounted preamps > with a Yaesu FT-847? >> >> I picked up a couple of them recently, and they came with the control box > (which appears to be a bias tee) that supplies 12 volts via the coax line, in > order to power them. >> >> The FT-847 can already supply 12 volts up the coax to mast mounted preamps; > but I wonder if these Mirage preamps require the use of the control box for > some reason.

SP-2000 Preamp?
by Burns Fisher 09 Aug '11

09 Aug '11

Hi, I've been listening on a couple of ARISSat-1 passes, both with the bird in sunlight. The first time I vaguely heard what might have been a voice. The second time (and this one was 80 or 85 degrees elevation) I could clearly hear that there was a voice, but could not understand, although some of the pattern sounded like the call sign being announced. I may have heard a bit of SSTV too; not sure. I'm listening with a Kenwood handheld, sometimes with a 1/4 after-market antenna, sometimes with a 2M eggbeater. So clearly I need something better. Since I can pick up the ISS well enough, I think I probably need a preamp. Maybe if I were retired and had more time, I'd build one, but for now, I'm thinking to go for the top-end; that appears to be an SSB Electronics SP-2000. But so far, no answer nor return call on my message to SSB. Does anyone know of a different place to buy these things, or do they only feel through their rep? How about second hand? Anyone looking to sell one? Of course any other suggestions welcome too... Thanks and 73, Burns, W2BFJ

Diffference between high and low power modes on ARRISat-1
by Mike Ryan 09 Aug '11

09 Aug '11

Whats the difference between high and low power mode? I know its determined by being in eclipse or not and I believe high power is 0.5 W on SSB and FM. But no luck in finding more info than that on the web about power. So far, all passes I’ve been able to copy here Eastern US are late at night (11PM-1AM) so I’m assuming I’m getting low power mode.

Mirage preamps
by Sebastian, W4AS 09 Aug '11

09 Aug '11

Before I destroy these, is anyone using Mirage KP-2 mast mounted preamps with a Yaesu FT-847? I picked up a couple of them recently, and they came with the control box (which appears to be a bias tee) that supplies 12 volts via the coax line, in order to power them. The FT-847 can already supply 12 volts up the coax to mast mounted preamps; but I wonder if these Mirage preamps require the use of the control box for some reason. I would prefer to use the rig to power the preamps, but the manual doesn't mention that option. 73 de Sebastian, W4AS

I gather ARISSat-1's total power output is 500 milliwatts. How many milliwatts of that is allocated to each of these downlinks - FM transmitter - BPSK Beacon - CW beacon - Transponder I couldn't find the figures on a quick read through the ARISSat.org they may be there somewhere but I didn't spot them. 73 Trevor M5AKA

Can someone point me to the ARISSat-1 mode schedules ? During the recent pass, ARISSat was the first pass in low pwr mode. During the (short) active periods I could relay short CW beeps over the transponder @5W. Midway the pass the satellite came in the sun and switched on and stayed on. But now the transponder was off. Is there an overview of sequence of modes, eg when SSTV is on Xponder off, etc. ? Henk, PA3GUO,

ARISSatTLM

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? I run it all the time but if the system shuts down and restarts for a Microsoft Update or whatever, I can only restart ARISSatTLM automatically (startup folder) and have to (later) tell it to start the sound card. An "automatic" setting would let it run all the time without missing anything if the system restarts when I'm not around. Or perhaps one exists, I just don't know it?

Problem is the wav file I have is large so I cant send it to you to try. Perhaps some one has 30 seconds worth that does decode, then we can use that as a standard to check our systems. I've been tracking doppler by hand. Seems to work OK but it's very important to keep the CW in the 'blue' window. I would think jumps would not be good. Perhaps frequent doppler updates. - So very small jumps. I also heard HB9 last night on the transponder, but in low power mode (45 sec)that is difficult. - I'll wait for some daylight passes.

Let's consider what we got from the Russians: they gave us a FREE 26 kilogram launch to low Earth orbit, with 20 times the mass and 75 times the volume of a 1U Cubesat, which is currently the only type of satellite that Amsat can hope to pay full market price for launching. NASA donated the six solar arrays and gave us a ton of help with export paperwork which would have been a bear if we had to export the satellite to Russia by ourselves. For this fact alone, we should be grateful to both agencies, because nobody else has offered us a 26 kilogram launch in the past decade. In spite of this, we still need to conduct an Anomaly Review Board to examine the reasons why the satellite was launched in a state of less than 100 percent readiness. This is not to assign blame but to see how we and our launch partners can improve the procedure for the next launch. The fundamental difference between educational satellites and amateur satellites is that educational satellites can be considered successful if they deliver a working satellite to the launch pad, it does not need to work on orbit and the students who built it have probably graduated by the time it gets launched. Amateur satellites are supposed to perform a useful communications function for some amount of years in a hostile environment. The best thing that Amsat can contribute to the student built satellites is to teach them to think about designing for reliability and long life, not to consider the mission successful if they collect a few weeks of telemetry from their beep-sat once it is in orbit. I agree with Phil Karn on most of his points, but the hams who are out there collecting countries and grid squares are also testing our communications infrastructure under real life conditions, without them we would only be doing a laboratory experiment. Hopefully some hams are bringing the kids along on their grid square expeditions to show them how we communicate under adverse conditions. I have often compared Amateur Radio to fishing: if you just want to eat fish it is certainly more cost effective to buy your fish at the market instead of wasting all that time trying to catch your own fish. Yet many people still enjoy fishing just for the challenge of testing their abilities under sometimes adverse conditions. In my case I still plant little tomato seedlings in the ground in spring time, waste lots of time watering and weeding them, waste lots of money on fertilizer and bug spray, and hope I can get a few tomatoes before the deer and rabbits get them, it certainly would be cheaper and easier to buy tomatoes at the supermarket. That is why we do Amateur Radio, we want to communicate in the least cost-effective way possible because we seek the challenge of doing it ourselves instead of using equipment that any dummy with a credit card can buy at the mall. As for why Amsat did not receive credit for building the satellite by either NASA or the Russians, journalists are a lazy bunch who like to copy from press releases and from each other. Universities and Government agencies have full time public affairs offices with people who know how to get their stories into print and on the air in a way that best serves the interests of their organizations. We at Amsat don't know how to play this game and don't have the connections to do so. Students building little satellites in school is a cute story that practically writes itself, but journalists don't know how to explain amateurs building satellites in their garages and using them to collect QSL cards and grid squares. In the aerospace industry, "Educational Satellites" are good, they are training students who the industry can hire cheap (while getting rid of the older engineers who earn too much money), but "Amateur Satellites" are bad, because if a bunch of amateurs can build long lived, useful satellites in a garage, then why is industry charging 100's of millions of bucks for a satellite? Jan King gave a talk at a professional meeting years ago and reported that certain business officials and military officers walked out of the room because they did not want to hear any more of his talk about our "garage satellites". It is too much of a threat to their established way of doing business. Anyone who has tried to find an engineering job recently knows that there is no shortage of engineers, but lazy journalists keep reporting about a crisis in STEM education and how we need to inspire the next generation to study science and engineering. The universities who need a steady stream of incoming freshmen, the industry which needs a steady stream of fresh inexpensive young blood, and government agencies who need to justify their existence love to play the STEM education card, even though most of it is not true. It seems that every university in the world is building satellites but I doubt that even five percent of those students will find jobs in that field, and those that do will find that they have much less design authority and freedom when they are working for the big boys. However I am willing to let Amsat play along with that game, if we can get our satellites launched along the way. I will leave it for others to debate the ethics of that action. We live in a hostile world where most organizations do not have our interests at heart. As in any business deal, we need to use them to get what we want in exchange for giving them some of what they want. Use the educational aspects to get our payloads into space, but recognize that our goals are sometimes different from theirs. So let's celebrate what has been accomplished, learn the lessons from the mistakes that were made in final assembly, preflight inspection and deployment, and start planning ARISSat-2. If the Russians want to claim credit for building it all by themselves, so long as they put it into orbit first, I'm OK with that. Dan Schultz N8FGV

Hi, Zarya is a small but important part of the international space station. It is one of the first segments built and launched by the Russians, and contains the airlock they the Russians often use (and did use last week) for their spacewalks. ISS is how we generally refer to the International Space Station as a whole, while we might say Zarya (or Kvant, or ...) if we are talking about a specific part of it. ARISS is "Amateur Radio aboard the ISS". And (you did not ask but) ARISSat-1 is the amateur radio satellite built by US amateurs with hardware supplied by a number of US and Russian companies and universities, launched to the ISS by a Russian vehicle, and recently released from the ISS (from a location on Zarya) by Russian Cosmonauts. The ISS has a ham station aboard which is separate from ARISSat-1. The ISS station has more power and is easily readable by a small handheld 2M radio with a 'rubber ducky' antenna. However, it usually is sending digital data, so without the decoding software etc it is not too interesting. ARISSat-1 has a fairly low power transmitter (1/2 watt I believe) which is more difficult to read. Some have picked it up with pretty small rigs. You would probably do better with a pre-amp. It has FM voice modulation as well as CW, SSB data, and an SSB mode u/v transponder. Look at www.amsat.org to find pointers to more about this stuff, frequencies, orbit calculators, etc. Hope this helps, Burns, W2BFJ > Date: Mon, 8 Aug 2011 17:01:27 +0430 > From: "N.
