AO-51 V/S MODE
by Luc Leblanc VE2DWE 28 Aug '06

28 Aug '06

My former AO-40 stuff is still working with a S9 plus 20 signal all my 2.4ghz QRM is going down the drain. Sweeping the band up and down and i notice much more less QRM from devices than a couple of month ago. I just show to one of my fellow neighbour that i can access the internet through his WI-FI router. He doesn't like my demonstration and and he shut down his WI-FI he kept only the wire function as he said after all he said his wife can access the internet from their living room where there is a wire this will free up his bed from the intenet... Just to say why so much fuss about going up keep at least a downlink on 2.4 for the next HEO birds? Just remember how many folks invest a lot of money on their AO-40 set up. I have near a 1000 QSO on AO-40 and all where conducted with stations using 2.4GHZ. I know for those who never make a single QSO on a satellite this is probably not significant enough as the wraith says they feed on us Q: Who are the Wraith? A: The Wraith are a powerful, hive-based species, who feed of the energy of living beings. I prefer Teyla Emmagan :) Thank's for the FO-29 help i found her buried in the noise of my LNK preamp in the shack as good it is on FM birds it works very bad on transponders type?

echo
by McGrane 27 Aug '06

27 Aug '06

I should explain my setup here; FT8800 dual band FM rig for recieve 8 element yagi with mast mounted 18 db hamtronics preamp 25 feet of 9913 coax I use narrow fm mode for maximum sensitivity. Whoever claims that leaves on trees attenuates UHF is correct but taking this into account I base my observations on clear path passes. I liked bruningas idea of reduced duty cycle or on time of the downlink. My experience with so-50 is that people would adapt to it quickly. A good way to save energy. One shouldnt correllate transmitter current draw with solar panel output current as the transmitters are not on for the entire orbit. This brings me back to the battery issue: How many cycles are the batteries expected to deliver versus depth of discharge? Is this information available on the web? Thanks, pat

BTW, I have bothe the original and current ECHO books. Thanks, pat n2oeq Hi Pat. The answer would seem to be: Echo works very well at it's current power setting requiring only modest equipment to use the onboard systems. To receive the satellite down to the horizon on every pass could be done by increasing the power towards its maximum of 4 Watts. However, the penalty would be to limit the other functions available to users and increase the depth of discharge of the batteries during each eclipse period. The effect of this would be to shortern the life of the batteries and the satellite. All of the above gleaned from messages and material referenced in the past few days. We don't need to ask Spacequest anything, we just need to improve our ground stations to cope with the power that is deemed optimum for maximum satellite lifespan. 73 David G0MIN AMSAT 51 on 51 award No fortysomething.

More on GPS time (was Re: Accuracy?)
by George Henry 25 Aug '06

25 Aug '06

According to the US Naval Observatory web site and gpsinformation.net, the leap second offset is contained in the NAV message sent every 12.5 minutes, along with 2 correction values (time difference and rate of system time change referenced to the USNO master clock), allowing most current generation time receivers and software to calculate UTC to within better than 40 nanoseconds of the master clock. GPS time itself is automatically "steered" to USNO UTC on a daily basis to keep system time within 1 microsecond, but has generally been "within a few hundred nanoseconds" over the last several years, since selective availability was turned off. No doubt this is how my Motorola Oncore software supplies accurate UTC time info.

Scott Sanford to address AMSAT Symposium Attendees
by Emily Clarke 25 Aug '06

25 Aug '06

AMSAT is very pleased to announced that Dr. Scott Sanford, NASA Principle Investigator and co-director of the NASA Ames Astrochemistry Laboratory, has accepted our invitation to provide a key presentation during our tour of the Ames Exploration Center. Dr. Sanford will speak on about sample return from comets and asteroids in general and specifically about the Stardust Sample and Return Mission to Comet Wild 2. Dr. Sanford was one of the original team members to propose capturing dust from a comet and bringing it back to Earth. Stardust was launched in February 1999, and in January 2004 approached Wild 2 within 150 miles of the nucleus, collecting samples and capturing detailed imagery of the comet's surface. On January 15th 2006 Stardust re-entered the Earth's atmosphere and successfully completed it's mission after landing in the salt flats of northwestern Utah. For Dr. Sanford, the investigation is just beginning as he and a team of 180 other scientists are hard at work to analyze the Stardust samples. This team will likely spend years unlocking secrets from the samples. Their efforts will lead to a better understanding about the formation of our solar system and perhaps even the origin of life on Earth and elsewhere in the Solar System. So be sure to join us Sunday afternoon for what promises to be an exciting event. There is no charge for visiting the Ames Exploration Center or attending Dr. Sanford's presentation. Round trip bus transportation from the Symposium Venue to Ames is available and costs $14. You can register for the bus online through the AMSAT store. The 2006 Space Symposium will be a joint meeting with the ARISS International Delegates and will also include the IARU Satellite Advisory Panel annual meeting, and a meeting of AMSAT International Delegates. For additional information please visit the AMSAT website at http://www.amsat.org. Click on the 2006 Space Symposium link in the left side menu.

Discussion regarding AO-51 power
by Bruce Robertson 25 Aug '06

25 Aug '06

Gang: I think we all know how Pat fells, trying to work out what is going wrong with a set-up, wondering if the power has somehow dropped in the transmitter, since its one variable we can't nail down. Someone in that situation might not be properly equiped to download telemetry, especially since receiving poorly is the original problem! That said, I think the team managing Echo are busy enough, and they do an excellent job reporting and calendaring mode changes. It isn't reasonable to ask them to log the output power in real time. Notice, however, that this email list provided the answer to Pat's question very quickly. I imagine anyone who asked such a question here could reasonably hope that some kind soul would answer within a day. I think it would be best expressed as a request for a favour, in any case. Finally, I should mention again that the book on AO-51 at the amsat store is an excellent read and invaluable reference regarding the details of this wonderful satellite. 73, Bruce VE9QRP

Is that the right amount? Yes (member), that is the correct amount. The AMS Code is automatically applied and can be found under the "Corporate, Group and IATA Identification (Optional)" field if you expand it by clicking on the Plus sign. AMS shows up in the "Group Booking Code" field. It's probably a good thing to check, but thus far there has been no problems with the 6 or 7 browsers I've tested. If you are calling the hotel or toll free number you need to mention the AMS code when you book. (In So Far As I Know) It doesn't matter who's points number you enter and I think in the last three years I've only been asked for my card once.

[Updated] Important Information about Hotel Reservations
by Emily Clarke 24 Aug '06

24 Aug '06

After reviewing the hotel contracts we discovered that our members are also entitled to the discounted rate three days before and three days after the symposium dates. We contacted the hotel, and they have made further adjustments to the reservation system. You can now use the AMS discount code for any hotel reservations from the 1st of October through the 13th. The following is a corrected set of instructions. 73, Emily --------------------------- It seems like we are running into a similar problem with the Intercontinental Reservation system as we did in Washington and Lafayette. When this happens, people making reservations are told that there are no rooms available. After speaking with the hotel we know what is happening and why, and it is really a bug in the reservation software that affects both the online system and the system the customer service representatives use. It is important to understand how the discounted rate system works in order to reserve your rooms successfully. We have a block of rooms set aside from the 4th through the 10th of October, and the discounted rate code only applies during that period. If you book a room outside that range the reservation software will tell you (or a customer service representative) that there are no rooms available. Here are some additional steps that will guide you to a successful reservation: 1) Make a reservation for within the dates of October 1st through the 13th using the AMS discount code. 2) Make a second (or third if necessary) for dates before and after that range. If you have difficulties call the hotel directly at (650) 570-5700 or call at 1-877-2-CROWNE. Be sure to give them the AMS discount code and explain the reservations you need as described above. You must make your reservations prior to September 13 to qualify for the discounted rate! Please Note: The symposium rate is for a standard room - you can upgrade to an executive room or suite at a discounted rate. 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Donate to AMSAT at http://www.amsat-na.com/donation.php Support Project OSCAR - http://www.projectoscar.net Personal Website - http://www.PlanetEmily.com --------------------------------- N1DID formerly W0EEC - CM87tm Donate to AMSAT at http://www.amsat-na.com/donation.php Support Project OSCAR - http://www.projectoscar.net Personal Website - http://www.PlanetEmily.com

I replaced the final IF transistor pair, NEC 2SC3357, Mouser part# 551-85634 which are a 1.20 each plus shipping. (I ordered a few spares in case this happens again! The unit is working fine and is currently copying AO-40 telemetry. Now need to order one of those Protector or Safety Bias Tee devices... Interestingly, when I removed the old transistors the center pins on both of them (collector)had physically separated from the case, apparently occurring when I transmitted into it. Guess this protected the other devices upstream. 73, Ken, W7KKE ===============================================================================

Hi guys and gals thanks to brian, amir paul, and drew for the advice on a simple tracking program. Instanttrack looked pretty good but I chose not to use it as there is no demo version. I didnt want to buy without knowing if it worked on the handheld PC first. I found a little calculator program called Real95 in the archives that works very nicely on the Handheld PC. It only shows a tabular readout of elevation, azimuth, and range but thats fine. Thats all I need for portable operation. All the advice is greatly appreciated! 73, patrick N2OEQ

67 Hz PL Frequency Tolerance?

I've looked through the AMSAT web site and the AO-51 book but can't any information about the frequency tolerance of the satellite receive system to the 67 Hz PL tone. I believe someone way back when actually did some measurements after it was launched but I can't find it either. Does +/- 2 Hz sound right? What about the level (deviation) require? Is it the same for the Mode V and L receivers? Regards and thanks...Bill - N6GHz

OSCAR-11 Report
by Clive Wallis 22 Aug '06

22 Aug '06

OSCAR-11 REPORT 19 August 2006 OSCAR-11 IS BACK! During the period 17 July to 19 August 2006 the satellite was heard on 26 July for a few orbits, and then from 16 August. At the time of writing it is currently transmitting. Observation of the 145.826 MHz. beacon transmission times, indicate that the watchdog timer has timed out for five periods of 20.5 days during the eclipse season. The eclipses have now ended, and the satellite should be in continuous sunlight until next year. If the normal watchdog timer sequence continues, the beacon should switch OFF around 26 August, and restart around 06 September. On 26 July real time clock showed an error of 64.5 days, an increase of 41.7 days since it was last heard on 05 May. The clock is now showing further problems, the date is now 53 July, but is still incrementing. The hours are showing an erratic behaviour. I am indebted to Peter ZL3TC, Dave G1OCN, and Dave WB6LLO for their reports and for monitoring the satellite, during this period. Many thanks. The current status of the satellite is that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 are still working. The spacecraft computer and active attitude control system have switched OFF, ie. the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed. 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 22 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 watchdog timer now operates on a 20 day cycle. During the three months before May (when the eclipses started), the ON/OFF times were very consistent, and the average of many observations show this to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website which contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry.

High Power 10m Uplink to PCSAT2
by Robert Bruninga 22 Aug '06

22 Aug '06

We need high power 10 meter CW or PSK stations to test The PCSAT2 10m ==> 2m transponder asap. PCSAT2 mission ends on 30 August (just 8 days away) and To date, no one has reported using the 10m uplink to 435 MHz downlink transponder. We know the transponder Is quite deaf, but to date, for the last several months We have not had any reports of anyone making the transponder Or even trying. We'd sure like to hear someone confirm that they transmitted 500W Or more and are certain that they did not hear anything. Anyone Can hear the downlink with just a simple 435 MHz FM rig. The Downlink carrier comes up just fine. What we need are high power Signals on the 29.401 uplink. CW, PSK, anything. So even if you don't have a KW on 10m, pair up with an HF friend That can generate lots of power and have him transmit on 29.401 MHz During a pass, while you listen on the 235.275 MHz downlink (+/- Doppler). Anyone can SWITCH-ON the transponder by simply sending a 1200 baud Packet CONNECT-REQUEST to "PCSAT2" on 145.825 uplink. That "connection" will trigger The 29.401 to 435.275 MHz transponder to come up for the duration Of the connection or 1 minute which ever ends first. During that time, everyone will hear he downlink which is just The audio out of the 29.401 SSB receiver. We want to see if Anyone can get in on 29.401 or 29.402 MHz CW or PSK uplinnk. Send results...

Missing postings to AMSAT-BB

Hi all. Why might it be that very occasionally my postings to the AMSAT-BB never seem to arrive? It has happened three times (I think) in the past month or two but I have not established a pattern.

I sent one the other day (a reply to another posting) and included SAREX in the To: list but only the SAREX copy arrived. So could it be an intermittent fault with the AMSAT-BB mailer daemon?

Does anyone know of a substitute replacement that would work?. I'd like to give it to another amateur friend if it can be fixed.Any help will be appreciated. 73 de Scott VE6ITV

Hi to the list, due to change the antenna cables, I would like to know which is the better one at least price For the Satellites activates. Unfortunately I have to use a long descent. I want also install my old 23 elements antenna for the 1,2 GHz. So the cable should be all for the satellites activates and should be for 2 meters 70 centimetres 23 centimetres I would like also to get a Mast preamplifier for the 23 centimetres. I already have the Mast preamplifier for the 2 meters and the 70 centimetres. They are both from Dressler and both has the EVV Interface. Please let me know which one is the better one at least price and if it needs also of the interface. Please let me know prices and where to get them Any suggestion will be really appreciated.

Mirage Preamp Setting
by Richard Lawn 21 Aug '06

I'm about to mast mount a new Mirage 70cm preamp. It has a high/low setting. Any suggestions from the group as I'm sure many of you are using this preamp. Is the high setting too much gain? I got tired of forgetting I had the ARR preamp on an frying it by sending too much RF into it. 73 Rick W2JAZ Richard Lawn, Dean College of Performing Arts University of the Arts 215-717-6125

Noise level problem
by Luc Leblanc VE2DWE 21 Aug '06

21 Aug '06

We are always struggling with the noise level. On HF VHF UHF and on microwaves it is our worse enemy. We are playing with preamps, fliters, low loss feed lines but it seems we forget one source of noise 'The voices from the deads..' or the voices of the other side. If you live near a cemetery could be your noise figure can be higher than normal! Did any one ever check this possible noise source? For those who wants to push their own investigations just go on: http://www.aaevp.com/index.htm In the recent interference thread, nobody mentioned this world-wide noise source, An interresting new way to have fresh news about our future HEO launch... :) Or at least it can help some with a good QSO to get a second advice warning on our moves? Could be AO-7 has been awakened from the deads by theses voices? If you enter in a discussion just ask your other party if he/she can do something about AO-40? He probably switch on their frequencies that's why we loose it on our side. In our present situation could be asking the deads can produce more results! if not nobody will notice... Business as usual... "-" The medium is the message...The content is the audience...;) Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe

SatPC32 G5500 Flip or 450 deg Turnpoint analysis
by Simon 20 Aug '06

20 Aug '06

Hello, Has anyone any thoughts on what is the best way to go with SATPC32's options that allows you to select either an elevation of 0-180 degrees thus enabling Flip Mode, OR selecting the extended Azimuth option of 0 - 450 degrees. The latter disables Flip mode though. I am unsure which choice will give the most benefit for both Leo's and EME tracking? Thanks Simon, VK3ZSJ

Cheap LEO antennas
by Grant Zehr 18 Aug '06

18 Aug '06

I would also stongly recommend the "Cheap Yagi" design, especially for 435 mc. band. I used a 3/4 square wood boom and a full length 435 mc. "AMSAT" cheap yagi design. I built one for my AO-40 uplink and another for LEO's both worked great. Sand the wood so it is nice and smooth. If you can find a drill press you will have nicely squared elements. To paint it I use a white "exterior wood primer" from the hardware store which is for priming the wood surfaces on the outside of your house. If you get the good kind, it takes 2-3 days to dry completely. Then I painted it with aluminum colored enamel ("rustoleum" or similar). I picked up some Coaxial cables at a flea market with BNC connectors, cut one in half and used that 2 antenna drive cables. From the ground it looks just like a "store bought" antenna and more important it really lasts. My LEO antenna has been up for about three years and still looks like new. The other thing is to be really careful about letting water get into the coax. Just use some caulking and be sure to loop your coax near the driven element to form a "drip loop". Gravity will keep things dry. Don't crush the wood while tightening the mounting bracket. It is easy to clip the driven element to tune the SWR. If you have time use a file to trim it when you get close to the best SWR. This is a GREAT antenna, just use exterior primer and enamel paint to protect it. I prefer wood to PVC (and I have used PVC for other projects). I used it today to work EB1FG on FO-29 on an east coast pass which peaked at less than 1 degree elevation here! Grant Zehr AA9LC

FO-29 turns 10
by ANTHONY JAPHA 17 Aug '06

17 Aug '06

FO-29 is a wonderful, reliable bird. Here on the east coast, it's possible to work DX (Eu.) with low power and the equivalent of an Arrow ant. (My own experience is that the Arrow doesn't do well because of overload on 70cm, but when put on 2 booms--2 mtrs on 1, and 70cm on the other-- using 2 small tripods, it's usually fine.) On a recent trip to several QTHs up and down the west coast, FO-29 was almost always heard from predicted AOS to LOS, though without much activity. Sometimes a preamp was used, which made life easier, but that's by no means essential for routine QSOs. A big disappointment on that trip was AO-7, which, even when it's in mode B (I didn't have mode A capability operating portable at oceanside QTHs), was nearly impossible to get into. I was using 5 watts on both FO-29 and AO-7 from excellent QTHs. I was not able to make a single QSO on AO-7, though a few stations were heard. I have seen reports of good success with 5 watts and small antennas on AO-7, but I can't verify that experience. I'd appreciate your thoughts on whether I should buy a 20 watt amp. and try that on AO-7. Long live FO-29! 73, Tony, N2UN

I talked with Bernardo on AO-51 this morning, and he said he will be in DL37 (a desert in southern Baja California) tomorrow. He previously mentioned via e-mail his plans to be on from there and other grids in the area (DL27, DL28, and DL38) between Friday 18th and Monday 21st, saying he would spend the most time in DL27 and DL37 with maybe one pass each for DL28 and DL38. All of the satellite work will be via AO-51. The rest of the weekend will be spent working the ARRL 10 GHz and Up contest from down there.

Re: Problems with my 9600 baud stuff
by James Cottle 16 Aug '06

16 Aug '06

Hi Tom, Tnx for your advice. I have now diagnosed several problems successfully. 1) I am using RHCP, which makes signals from AO-51 weak, complicated by the fact that I have a 15KHz offset which is further complicated by doppler and 2) turns out that, when one puts the 910H in "satellite mode" the data port receive gets switched as well. This morning I was able to copy strong TECHSAT beacons throughout its pass and strong voice on ECHO (The passes conflict right now). THanks for your guidance. SOmone needs to document this stuff for others!!!! maybe on a web page somewhere (in my spare time). Once again you pointed me in the right direction. Thanks for the hints. The offset on the 910H is well known...what is NOT well known is that, when you get down and dirty in there, you cannot adjust it out with the standard XTAL PLL oscillator. I have some pretty good test gear here....all of the tools but none of the talent (hi hi). 73 Jim N6FO Thomas McDaniel wrote: > Hi Jim, > > AO-51 is RHCP for voice and LHCP for digital -- I'm using the KLM > 435-40CX with the switching relay.

Does anyone know if PVC (Schedule 40) can be used as a substitute for wood?
