AO-51 Cardboard Model needs test builders!
by Stefan Wagener 03 Feb '08

03 Feb '08

AO-51 Satellite Cardboard Model Hi folks, I have just finished the 1st prototype of an AO-51 cardboard model design and would like to give a few dedicated individuals the opportunity to actually build the model and help me with the final design and the necessary instructions. At this stage I will need individuals that have built cardboard models (ships, airplanes, rockets etc.) before and don't need detailed instructions but know the tools that are required to assemble such a model. Pictures of the current prototype can be seen at: www.msig.ca/model.html It is still a work in progress and hopefully will end up as a product that AMSAT can offer for a donation. I designed the model in a 1:1 scale but for the purpose of this project it has been reduced to 75% size. This will allow builders to print it on regular size photo paper and still have a beautiful model for display in the shack or wherever. Building the model will require time, patience and a color printer since the model is distributed as pdf files. This form of distribution will save me paper and will allow you to print it as many times as you need (trust me, once you messed up the first piece, you will be glad that you can print it again). As mentioned above, I am looking for up to five test builders (with experience) that are willing and able to finish the model in four to five weeks. No, it is not a two hour project and dedication to detail and exact cutting and gluing is required. Those that help and provide me with updates on their progress and final feedback will get the final distribution files as well as the model files in a 1:1 scale. Send me an email off line if you are interested! 73, Stefan VE4NSA

SuitSat 1 Anniversary !!
by Stefan Wagener 03 Feb '08

03 Feb '08

Message from Frank Bauer, KA3HDO .............. All, Today marks the 2nd anniversary of the deployment of SuitSat-1/Radioskaf/AO-54 from the ISS. I want to take this opportunity to thank all the volunteers around the world that supported the SuitSat-1 development, deployment, public outreach and ground station reception. Despite its lateness, I would also like to announce that the SuitSat Certificates have been mailed to the regional QSL distributors who will, in turn, mail these to you in the very near future. Specifically, this is the ARRL in the U.S. and ARISS-EU in Europe. The Canadian certificates were mailed directly to their QTHs. I will take responsibility for the lateness in delivery of these. My extensive work travel over the past two years coupled with needing to focus on keeping the ARISS program alive despite looming budget threats were factors in not getting these to you in a timely basis. I hope you will enjoy them, just the same. I ask that you please wait for about 2 weeks before making further requests regarding the certificates. I would expect that they will be in your hands in that time frame. At the end of February will we make a second call regarding the certificates, if for some reason you did not receive it from us. 2008 brings new opportunities to you, the hams interested in ARISS. This, as we plan to commemorate the 25th anniversary of human spaceflight ham radio operation---the flight of Owen Garriott, W5LFL on the space shuttle Columbia, STS-9 in 1983. As you know, we are working to bring SuitSat-2 to reality. It is not clear when it will be deployed, but we are working feverishly to have it ready for deployment before the end of the year. And we expect to have significant ARISS crew participation starting in the October timeframe with the launch of the Expedition 18 crew and Soyuz taxi flight. As we get more details on specifics, the ARISS team will inform you through e-mail and the ARISS and ISS Fan Club Web sites. I thank all of you for your interest in ARISS. This program is truly inspirational for students, the ham radio community, and the communities surrounding the schools that have been touched by the 334 (to date) school contacts conducted since December 2001. Enjoy the currently operational ARISS voice repeater! 73, Frank H. Bauer, KA3HDO ARISS Internatonal Chairman AMSAT-NA V.P. for Human Spaceflight Programs

Stretching the footprint!!
by Frank A Cahoy 03 Feb '08

03 Feb '08

Congrats Bob. I'm actually jealous. I have yet to hear Europe on AO-7 but that's only because I've been very QRV on HF. I'm sure it can be done from DN81. It's a feather in your hat no matter how you look at it. I think I'll throw my hat into the ring for footprint stretching. I have to go back to AO-40 for my bragging rights. On 20 Oct. 2003 I worked VK9CD in NH87 and that figures to about 10073 miles to DN81. I was hearing the fellows on the West Coast work VK9CD and again, I was very jealous because I figured I had but only 8 to 10 minute window under the best of conditions. To make matters worse the window was totally below 10 degrees of elevation. Then rubbing salt into the wound was a very tall line of Chinese Elm trees between my sat antennas the horizon. When I saw that I had a slight chance I began calling them. The West Coast guys told me that VK9CD was hearing me! I could not hear them or my own downlink. Determination was also the key for me. I finally heard them ever so faintly just as LOS was almost on us. All of the sudden I heard my call clearly and distinctly and the exchange happened in literally, the last few seconds of the footprint. I stepped out on my front steps to try and figure how such a piece of great good luck could have happened. Looking up at that row of trees I saw a "hole" through the leaves about the size of a bushel basket. My prize piece of AO-40 DX was worked in the few seconds that the bird was actually "line of sight". BTW, all of this on CW!! This may be off subject a bit but I've been a DXer for 47+ years and that was by far one of my most memorable QSOs satellite, HF or otherwise. I was never tempted to post the above story until Bob's good fortune on AO-7. See what great fun we could have with an AO-10 type bird up in an HEO!! That's it. I'm climbing down off my soapbox. 73 to all. Frank, KØBLT

AO-16 in repeater mode
by Jim White 03 Feb '08

03 Feb '08

In ANS this week the note on AO-16 is a bit incomplete regarding the current state of the satellite. Here is some further detail. The on-board computer has not failed. What is no longer working is the computer's ability to access the EDAC SRAM needed to run uploaded software. The boot loader (MBL) software was burned into ROM prior to launch and continues to run. The processor itself works OK and is running that MBL software just fine. One of the unique features of MBL is that it does not use any SRAM but runs entirely in processor registers. It also does not use DMA or interrupts. One of the design goals was for it to continue to run even when several hardware things had failed - and that has proven to work well now that the SRAM access no longer works. With the computer still processing instructions and running MBL it remains possible to send commands directly to various hardware modules using the AART bus (another innovation in these satellites). It is that capability which allowed the mode to be switched. Further, we know the computer continues to successfully run MBL because any glitch in processing would likely reset the computer. That would cause MBL to restart and reset the hardware to the default, turning off the U TX, and resetting the downlink to digital. Should that happen it might be possible to get it back into the repeat mode, and perhaps do that more than once. But at this point it's anyone guess how long enough hardware will work to allow more use from this rugged old bird. Jim jim(a)coloradosatellite.com wd0e(a)amsat.org

I can understand this statement, however..

None of my low power eme qso's had pre filled in fields waiting for pro-signs to confirm a qso.

February 3, 2008 To All RADIO AMATEURS BID: $ANS-034.02 Many thanks to all who participated in AMSAT's Straight Key Night on OSCAR 2008, held in memory of Haruo Yoneda, ex-JA1ANG. Only two linear-transponder satellites were available this year, AO-7 and VO-52. Two enterprising hams, W6ASL and WA8SME, didn't let that stop them: they used audio oscillators to work each other through the FM transponder of AO-51. That counts too! The silence of FO-29 notwithstanding, a record 15 amateurs each received at least one Best Fist nomination from someone they worked. The increase in European activity was especially welcome. This year's winners are: Jay Garlitz, AA4FL Sergei Pyatygin, ER1AN Laszlo Kekes, HA5FB Ron Gorzynski, K8DID Frank Wiesenmeyer, K9CIS Scott Newell, KA8HOK Keith O'Brien, N4ZQ Allen Mattis, N5AFV Al Ozias, N7EQF Rolf Moberg, OH6KXL Andy Macallister, W5ACM Jim Van Striver, W6ASL Mike Herr, WA6ARA Mark Spencer, WA8SME Neven Mrduljas, 9A5YY Congratulations to all.

February 3, 2008 To All RADIO AMATEURS BID: $ANS-034.05 OSCAR-11 Report for 26 January 2008 This report covers the period from 19 December 2007 to 26 January 2008. After two months of silence from 20 November, when eclipses started, the satellite resumed transmissions on 22 January 2008. At the time of writing signals are consistantly strong, although the polarisation is very variable, with a cycle time of around 20 seconds, causing deep fading if the antenna polarisation is fixed. This suggests that the satellite may be tumbling. If the current watchdog cycle continues uninterrupted, the 145.826 MHz beacon should switch off around 01 February and on again around 11 February. However, if low battery voltage causes the watchdog timer to reset, then the beacon should switch on 21 days later. I am indebted to Peter ZL3TC, Mark KU7Z, Gene WA4UKX, SWL Mark in CM87, Ron G4PGY, Julian WB9YIG, John HB2HSH and Edward BX1AD for their reports. Many thanks. The satellite is now in continuous sunlight, and this is expected to continue until mid March, when eclipses will start again. Unfortunately eclipses will then become a permanent feature of the orbit, which is likely to prevent any periods of sustained operation after March. When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus. After 23 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude. The Beacon frequency is 145.826 MHz. (AFSK FM ASCII Telemetry) Listeners to OSCAR-11 may be interested in visiting my website. If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear. There is an example of the latest telemetry received from the satellite.

ARISS School Contacts Status Due to crew schedules onboard the ISS, no Amateur Radio on the International Space Station (ARISS) contacts are planned at this time. The ARISS team expects contacts to resume once STS-122 launches in early February. 2. STS-120 Crew Talks with Italian Students On January 22, STS-120 crewmembers visited “La Sapienza” University in Rome where approximately 600 students from several universities and high schools gathered. Among those in attendance were students from the schools that participated in ARISS contacts with astronauts Paolo Nespoli, IZ0JPA, and Clay Anderson, KD5PLA. The crew gave a presentation on their mission which included educational activities, and showed videos to their audience. The complete story and photos of the event have been posted on the ARISS Web site. See: http://www.ariss-eu.org/2008_01_25.htm 3. Astronaut Training Status On Wednesday, January 23, Russian cosmonaut Oleg Kononenko, RN3DX, participated in a simulation of an Amateur Radio on the International Space Station (ARISS) school contact. The Kenwood D700 radio in the JSC Service Module mockup was used for the contact. He spoke with the training support team who participated as students, asking Oleg questions about space and his visit on the ISS. Kononenko is scheduled as a flight engineer on Expedition 17. A basic Amateur Radio on the International Space Station (ARISS) operations and school contact class was held with Soichi Noguchi, KD5TVP, and Koichi Wakata, KC5ZTA, on January 24. Wakata is scheduled to fly to the ISS on 15A (STS-119) toward the end of 2008 as Flight Engineer-2 during Expedition 18. Noguchi is the backup for that flight and could participate as part of the 6 man ISS crew operations in 2010. Mike Barratt, KD5MIJ, has been scheduled for an ARISS training session at JSC on Tuesday, January 29. Barratt is a backup crewmember for Expedition 18. 4.

Tracking program VS doppler corr
by Luc Leblanc 03 Feb '08

03 Feb '08

Feed up in running after my tail i give a try to a doppler tracking program on AO-16. I could be put the bar a bit too high using this one but i ended always off by a couple of KC on the RX side (probably the same on TX uplink) I guess i will have to play a bit with some parameters? i'm using Nova and FT-847 super control. I guess the benefits will be more visible on the transponder type? Thank's for your inputs and here is "another" tracking program but on line and based on your IP address http://www.n2yo.com/ "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

TNX for the AO-16 QSOs!
by Andrew.MacAllister＠emerson.com 03 Feb '08

03 Feb '08

Howdy! We are just finishing up our cruise to the western Caribbean (W5ACM, W5GFP, WA5TWT, WA5WOD, N5RPQ and WB5RMA). Over 90 QSOs were made using my call W5ACM/MM from the Carnival Conquest. We made some AO-16 passes with excellent results, but I must admit that it is a bit difficult to do FM up and SSB down while standing out on the deck of a ship with handheld gear! Most of the contacts were via AO-51 (much easier), but we were amazed at the signal strength of the AO-16 downlink. It was REALLY EXCELLENT!! 73 de Andy W5ACM/MM

Re: 25 watt Moonbounce
by Oscar Diez 02 Feb '08

02 Feb '08

Hi list, I am using a homebrew single 6 el. Yagi (DK7ZB design 10.15dBd gain) on the terrace of my house (approx 8ft above ground on a tripod))for "QRP EME" operations regularly. I am running about 90-100 Watt into this antenna (approx 1 KW ERP). This is real QRP for EME standards. See here: http://www.arrl.org/contests/soapbox/index.html?con_id=146&call=DJ0MY&bbycal l=1 Usually Gary KB8RQ always comes back on my first calls (even without prior announcement of my call in one of the usual EME internet chat rooms). Thus, I would guess that it would even work with much less power (I just never tried it)...so it seems "normal practice" at least with big gun stations of the size of KB8RQ, W5UN, etc. I would even say if he could work KB8RQ with 25w he should give RN6BN a try with only 10-15w (he uses most likely the largest private array on earth since he has recently expanded it). The smallest station he ever worked via OSCAR 0 was a 4 el. yagi with 40W. I am sure you can even decode him on a dipole+preamp, since he has exorbitant strong signals (even compared to other big guns). RX is generally not the problem: I can copy 2 and 4 yagi stations very frequently. I even copied some single longyagi (6 lambda boom length) stations with my tiny antenna in the past a few times. The only problem is the return path where you simply would need more HF power. In total I have already worked about 8 stations (the smallest were 8 yagi group stations) and had more than 15 QSOs with my tiny setup during the past year. This is of course only possible with the help of WSJT software and JT65 mode, hi !!! Otherwise we would still be stuck in EME stone age. 73 de Oscar DJ0MY

AO-7 DX claim

Hello I'm not sure if this contact is a record distance, but I will claim it until I'm knocked off my pedestal. At about 1915Z I worked Mika-OH8MBN in KP24, I'm in CN87 (running 8W John). This works out to 7229Km or 4493 miles. Mika and I have been trying to connect for several days, the window is really really short. QSO was on SSB with KC8ZFN as a witness. Has anyone else "stretched" the footprint. 73 Bob W7LRD Seattle -- "if this were easy, everyone would be doing it"

JH3XCU/1 and AO-7 web site
by DeYoung James 02 Feb '08

02 Feb '08

Greetings, I am not sure of the intent of a recent AMSAT-BB submission related to JH3XCU/1 and his entry or lack of entry of specific information into the AO-7 web site logger. As far as I can tell he is a competent operator. I also note when searching the web that almost all of his web information is in his native language (Japanese) and I therefore presume that there may be a language related issue possibly. If there is an issue with his submissions appropriate use of statistical filtering is always possible to do on the collected information. I probably have hundreds of QSO's via AO-7 where I only talked to myself, often times on purpose just to measure the loopback frequency. I don't generally even bother to log any loopbacks or QSOs anymore. In most cases others enter information from the other side of the QSO so I see no need to duplicate the information which is also a statistical problem depend on the use of the web site collected data. I hope we can all be more tolerant and give JH3XCU/1 the benefit of the doubt especially since he is a fellow licensed amateur operator. Best regards to all.

AO7 Operating Tip #1
by WILLIAMS MICHAEL 01 Feb '08

01 Feb '08

If the station your in QSO with has a easily readable 5/5 signal from AO7 but your signal is three times as strong, what action should you take? 1. Marvel how well your station is performing. 2. Immediately reduce your uplink power. 3. Do nothing, keep pounding the transponder. 4. None of the above.

Yes John I have read all the available information regarding the history and operation of AO-7. I trust you will take the liberty to CC this email to the EU AMSAT reflector. I should have reread my initial post to the bb, as the context is not correct. My apologies to all for the justifyable outrage this has caused. I conciously make every effort to follow all the rules written and unwritten. -- 73 Bob W7LRD AMSAT member 28498 Seattle -------------- Original message -------------- From: john hackett <la2qaa(a)hotmail.com> > > For those that don't understand power budgets on satellites - especially ailing > ones - *PLEASE* make the effort to read up on the subject - so you can honestly > say "your" operating *DIDN'T* shorten a particular satellites life ... or ... > you were *NOT* being an alligator ...

Re: Which Handheld...
by Clint Bradford 01 Feb '08

01 Feb '08

>>...which handheld do you use or which handheld is "the best" for sats. It must be full duplex. There are no new full-duplex HTs on the amateur market. The Icom IC- W32a was the last nit to have true full-duplex. Knowing that, the feature that is needed in an HT is the ability to RX on one band, and TX on another. So you have dual-band, dual receive HTs (TH-F6a from Kenwood...user un-friendly VX-7R from Yaesu) that can do it - obviously. I overlook the Kenwood TH=D7A(g) because it is a battery hog and much older technology than what is now avalable in amateur HTs. But there are also HTs that are dual-band, single-receive that work excellently. I show off the Yaesu FT-60R for my demos and sessions. 1,000 memories, strongest belt clip of any HT on the amateur market, built tough, 108-to-a-gig receive, easy to program...and, when using its optional AA dry cell case, you are working at FULL POWER! Unlike the TH-F6a - when you use its AA case, you're at 1/2 of one Watt. Al that in a radio for well under $200. See a picture of it in action in the December, '07 issue of CQ Magazine, where I am using the FT-60 with an Arrow antenna to wow an audience at a fair demo.

...Interesting. If you turn off the TNC when not in use, and set power save, it is no different from any other radio I think. And nothing has changed in FM "technology" in 30 years... I don't understand your bias... My "bias" comes from knowing from first hand experience that the radio is NOT anywhere near as efficient with its energy consumption than more current (no pun intended) HTs. That fac has already been acknowledged ny another participant here, too. They used to ship with a SIX VOLT battery pack - PB-38 - which only allowed 2.5W VHF and 2.2W UHF ops out of the box. (Ebay buyers beware!!!!) But they now ship with a PB-39, offering 12VDC at 600 0r 650mAH and a full five Watts power output. More modern radios are offering full power output with 7.2V and much longer-lasting NiMH and Li-Ion battery packs. Owners (including myself) have "compensated" the TH-D7's poor original battery life with aftermarket NiMH packs and the like...But in responding to the original poster's inquiry (limited funds), I still believe I gave him some good information. But if one asks, "I need a TNC in an HT...APRS intrigues me..." - then the TH-D7a fits the bill. Clint Bradford, K6LCS / KAF3359 909-241-7666

Explorer I
by Roy 01 Feb '08

01 Feb '08

If I'm not mistaken this is the 50th anniversary of the launch of Explorer I, the USA's first satellite put in orbit. I listened to the telemetry broadcast on 108 mHz and recorded it. The JPL had asked for the loan of any recordings made so I sent them out for their analysis. I received my original tapes back along with a supply of new reels of tape for use in making further recordings. JPL sent copies on to the Air Force Research Center at Cambridge. I later received letters from JPL and the Air Force Research Center describing the data they had recovered from the recordings relative to micrometeorite impacts and other items. It was a really exciting period for Amateur Radio. -- Roy -- W0SL

SPECIAL CONGRATULATIONS.
by John Hackett 01 Feb '08

01 Feb '08

Special congratulations ought to be extended to JH3XCU/1 for soon to become the 8th station worldwide to attain 1000 points in the AO-7 log. 'Special' congratulations are in order because the station concerned has made this magnificent effort WITHOUT ACTUALLY HAVING A QSO. Quite an acheavement. Yes, I know it's an "activity" log but it does rather make a mockery of the log when you consider the stations that actually communicate with eachother. Likewise the stations that claim QSO points but log the transponder as *OFF* are not helping the general statistics page. The log page does have a link explaining how to correct incorrect entries - (the - "remember me next time" - checkbox needs to be checked). If you're going to bother to make an entry in the log, you might as well check that you've done it correctly - and if not, rectify it ... otherwise the log won't serve the purpose as it was designed for. 73 John. <la2qaa(a)amsat.org>

Re: Satellite tracking programming ideas
by phillor＠telstra.com 01 Feb '08

01 Feb '08

> SatPC32 works similar as Instant Tune (see Anthony Monteiro's detailed > answer): Thank you Anthony and Erich for your replies. I'm always impressed by the generosity of this list's members. During the past week I've spent hours debugging my code because it was originally supposed to work the way that you have both described. Actually it did, or at least I thought it did, but that was before I bought a laptop computer and a USB to serial converter. The code has been updated many times during the past eight years and during one of those updates I changed the user interface so that the user had to stop the tracking during manual tuning; effective but clumsy. Reading the FT-847's receiver frequency originally caused me some frustration. I had included a delay after each read and write command because the FT-847 doesn't return a command acknowledgement. While writing this reply I realised that instead of a delay I shroud be waiting for the serial port to receive five bytes from the radio. This has turned out to be more reliable but I still get occasional read errors and I feel that it's due to the USB to serial converter. When an incorrect frequency value is read, at one second intervals, the same value is reread from the serial port buffer each second until the tuning knob is moved again. Maybe the read command is working correctly and instead it's the write command that instructs the radio to output it's frequency that's not working reliably. I remember reading about some sort of delay that the FT-847 requires but I cannot remember what it was all about. It could be important. A lecturer once told a class that I attended that explaining a problem to anyone, even your dog if no one else will listen, often leads to an answer. It's helping in this instance, but not enough to lead me to the final answer. To add to my frustration, my ISP has made changes to their mail server which now prevents me replying to any e-mails that are outside of their domain. I have a workaround but it's a real pain. Thank you Wayne for your thoughts on frequency drift. I spent many hours listening to AO40's beacon and did manage, eventually, to get the drift under control. -- Regards, Phil.

RFI source found - sort of
by Tony 31 Jan '08

31 Jan '08

All, I was able to track down the general location of an RFI problem I've been hearing since December. It's in the vicinity of 3 new homes on a cul-de-sac not far from my QTH. I'm told the pulse noise sounds like the RFI from an invisible electric fence. At this point, it's hard to tell which home it's coming from with the HF mobile because the signal strength is overwhelming at the location. I'll have to get up close with a portable AM radio; I'll probably need some shielding around it. Wish I knew exactly what the noise was; I'd hate to 'accuse' a neighbor of causing RFI and have it turn out to be the power company. I have a recording if anyone is interested. The question is, what to do in the worse case scenerio if the home owner decides not to take action to remedy the problem? Anyone on the reflector been through this before? Apologies for the off-topic note -Please reply direct... Tony -K2MO

I have a Compaq DL-360 server that I plan on posting on ebay this weekend. However if there is someone on this list that is interested in trading for it, I would be happy to consider it. Either email me for the specs if you are interested or I will post them tonight later. Thanks again, Chad kg0mw

Which handheld for sats?
by chad phillips 31 Jan '08

31 Jan '08

I don't want to open up a can of worms, just looking for your advice....... I have been off the birds for a few years and am wanting to get back on next month. Because funds are somewhat limited, I am considering every possible combination of radio(s) for getting back on the air. One option is to purchase a handheld that I can use with an Arrow antenna. I would like to know which handheld do you use or which handheld is "the best" for sats. It must be full duplex. Thanks in advance! Chad kg0mw en-13 Sioux Falls, SD kg0mw.blogspot.com
