Re: SatPC32 Icom706 Subtone enable for AO-51
by Mark L. Hammond 23 May '08

23 May '08

Hi Robert, Not a direct answer to your question---but AO-51 doesn't require any subtones for operation at this time :) 73, Mark N8MH --- I am using SatPC32 to control a pair of IC706MkIIG's. The CAT control with the SubTone "T" feature does not enable the subtone when trying to use AO-51. I enable the sub tone on the IC706 Uplink xcvr, toggle the T button to T1, but as soon as CAT control changes the frequency to allow for doppler shift, the tone function is disabled in the xcvr by the program even though T1 in the program is still enabled. What is the correct instruction code to enter in the SubTone.SQF file in SatPC32 for the IC706. The current command line in the file reads: AO-51,67.0,$3F,1. Any help is greatly appreciated. 73, Robert W6RQR -- Mark L. Hammond [N8MH]

FM satellites...
by Patrick STODDARD (WD9EWK/VA7EWK) 22 May '08

22 May '08

Hi! It is interesting to see all the messages and opinions on the "Organized Chaos" thread(s), and similar threads in the past, when it comes to the FM satellites. Sad, also. FM satellites, whether you want to accept this fact or not, serve as the entry point for those interested in satellites but not interested in a large outlay of $$$ for a satellite station. Many hams have the gear - a 2m/70cm FM dual-band transceiver, or separate 2m and 70cm FM transceivers - to give this a try. Some try it, make a few contacts, and go away. Others stick with it, never progressing beyond these satellites but enjoying hearing other people who come and go on these passes. Some go on to assemble nice stations for use with all sorts of satellites (I want to do this, once my situation stabilizes in the next few months). AO-51 provides opportunities to try something other than 2m and 70cm, a nice resource for those building stations for use with future satellites using 1.2 or 2.4 GHz or digital modes for example. AO-16 has been a nice challenge, with its 70cm DSB downlink - especially when using a portable station without the benefit of computer control. Although I have been unsuccessful in my attempts to make QSOs via VO-52 with my portable gear, I have not given up on that satellite. Here in North America, there are some crowded passes that don't allow for much more than an exchange of call signs and grid locators - not unlike working a big DXpedition or contest station on HF. Other passes have maybe a couple of other stations, and those are fun for having a little more of a chat to make use of the pass. There are people who will work an HF contest for up to 48 hours, with very little communication going on there - an enjoyable activity to them. Look at the results in CQ magazine for their big international contests, or the ARRL web site and QST for the ARRL contests, to see that. Others like me enjoy getting on the satellites for 10 to 15 minutes at a time, working whoever happens to show up. For me, it has been much easier to make time for these passes than to work any significant portion of a weekend HF contest. I see in the QSL cards I receive lots of "thanks for my first satellite QSO" or "thanks for my first Arizona satellite QSO" or "thanks for a new grid (or new grids)". My log has well over 600 unique calls in the 3800+ satellite QSOs I have made in the past 2 1/2 years, from dozens of locations in 4 states and almost 20 different grids. Sure, there are some who show up regularly, and those stations have been very helpful to the new operators. We need more of that. I've also engaged in lots of e-mail exchanges with those just starting out, giving suggestions and advice for those wanting to get started or wanting to improve on their stations. As for those who insist that FM satellite operation is about equal to the same degree of difficulty to cell phone operation... I'd like to know what cell phone requires one to adjust the receive frequency to deal with Doppler when making or receiving calls, for example. I don't remember seeing a VFO on my Nokia phone, either. A computer-controlled station takes care of the frequencies and antennas, allowing the operator to just make contacts - but this is hardly an "apples to apples" comparison with using a cell phone. If this was the case, that FM satellite operation was as difficult (easy) as cell-phone operation, why are demonstrations and presentations at hamfests and clubs popular events? We can build large and complex stations that many people think of for satellite operation, but there is the other extreme (handheld radio with handheld Yagi or long telescoping whip, for example) - like those using a used 100W rig with a dipole on HF, compared to towers and big Yagis and new rigs with amplifiers. I have read about those who used to travel all over, putting many different grids on the air in the past. There are some like N5AFV, W6GMT, and KD6PAG here in the US (among many others) who have done this for a long time and still enjoy doing that. I've done a little bit of that in recent months, operating from 11 different Arizona grids since March. There are a few Mexican hams who have been doing the same thing - XE2AT and XE1MEX have done this for a long time; in recent times add stations like XE2HWB, XE2JA, and XE2RV (among many others) who are doing the same thing in their areas. All of this is happening on the FM satellites. Why do we do this? Because it is fun! Would I like to have a high-orbit satellite to use? Sure! I would enjoy the opportunity to travel and put grids on the air for those outside of North America to hear and work. I would enjoy hearing other continents without dealing with propagation as on HF. I was not around this part of the hobby for the days of AO-10, AO-13, and AO-40. Like everyone else, I'm hoping to see P3E, Eagle, and the Intelsat-AMSAT venture (or anything else) put a high-orbit bird into operation. Until then, I will use what we have now - the FM birds, work on my station for VO-52 and AO-7 (I've heard myself in SSB through VO-52, but have to work better on hearing myself clearly on the downlink when transmitting when not using computer control), and have fun. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ (going to DM44 and maybe the DM43/DM44 line northeast of Phoenix on 24-26 May, then I'm off to a hamfest DM34 in the morning followed by DM25/DM35 in the evening on 31 May - all on FM satellites, with maybe a try for VO-52 during the upcoming weekend for my first non-FM satellite QSO)

I've been licensed for 57 years, on amateur satellites for 33 years (Oscar 7) and the FM voice operation is the most ridiculous aberration I've witnessed in all of amateur radio...Pandemonium exists here also!! It is pretty obvious NO COMMUNICATION exists on AO51,all of their communication is on here. Why do they bother to turn the radio on??? Many of us attended AMSAT a lot conventions in an attempt to discourage throwing that money "down the tubes" on FM voice, to no avail. Someone had an "ax to grind", and several of the existing "powers that be" in AMSAT-NA told me to "mind my own business". They were obviously the "ax grinders". FM voice on the amateur satellites is about equal to the same degree of difficulty as a cell phone operation! No wonder our membership is deteriorating. Ancient AO7 and present VO52 hopefully are keeping some interest, until Europe launches P3E.... That's where my donations go.....-----------Dave, As one of those who was present at the "birth" of AO-51(we called it "Echo" back then), I respectfully have todisagree with your assertions. I can assure you that nobody had an "ax to grind" in thatdecision. To the contrary, if you will recall, at that time wehad all but lost most of P3-D's on-orbit capabilities. Organizationally, our morale was very low. What's more, the BOD and officers were presented with a unique cooperative venture that offered our membership a new LEO satellite, complete with launch, for a relatively small outlay of capital resources. Naturally, we jumped at the chance. And, while FM operation may not be your particular "cup of tea" (and most of us operating there would MUCH prefer to have an HEO to play with), at least for the foreseeable future, an operational HEO on orbit is simply not in the cards. What's more, as Bob Bruninga has so eloquently pointed out, the FM birds DO serve a purpose in creating excitement among the general Ham population as well as serving as the entry point into more serious satellite operation for those who choose to engage in satellite conversations that offer something more than just a quick "hello and goodbye". As far as our declining AMSAT membership is concerned, while regrettable, I'm convinced this is simply just another reflection of the declining popularity of Amateur Radio in general. In case you hadn't noticed it, Dave, our Amateur Service is now, quite literally, dying. That's because our average age is approaching (and will soon surpass) age 60. I learned long ago that it is far easier to tear a house down than it is to build one. And sitting on the sidelines and passing judgment on decisions that have LONG since been made serves no purpose other than to create bad feelings all around. I'm sure the current officers and BOD members of all of our AMSAT organizations are doing their level best to get an HEO bird into orbit just as soon as they possibly can. However, we all must remember this is 2008, not 1968. The "space biz" has fundamentally changed into a multi-billion dollar, multi-national, military-industrial grab-bag of commercial launch companies, complete with an ever more dizzying array of government-induced, bureaucratic restrictions and regulatory limits regarding who (and/or what) can put which payload into Earth orbit. The bottom line here is that the days of "free" (or nearly free) and unencumbered satellite launches into Earth orbit are long since over. The sooner today's AMSAT members recognize and accept those fundamental changes that have occurred in a business that their predecessors in AMSAT largely helped create, the better off everyone will be. And if operating on our FM birds continues to give you heartburn, then may I suggest you (and others so 'heartburned") simply not operate on them? 73, Keith BakerKB1SF / VA3KSFPast President and BOD MemberAMSAT-NA

Delfi-C3 heard by anyone recently ?
by Henk, PA3GUO 22 May '08

22 May '08

I did not hear Delfi-C3 yesterday evening, and also not this morning (Sat) during the full sun / max 90 degrees elevation pass. Btw I also scanned the other 2 mtr downlink freq. For me this is new, that the sat is totally quiet during entire passes. Did anyone hear this sat recently ? ps: would be nice to have, like for example we have it for PCSAT and ISS, a realtime website where the latest received packets are visable. then I would see eg that last reception was 2 hrs ago over US by K6xyz(for example).

DO-64 heard over VK
by David 21 May '08

21 May '08

Hello All, Just caught the end of a pass over VK. By the time I had the computers/radio/tracking fired up and synchronised RASCAL, i managed to capture 26 packets. On the earlier pass this morning I heard SEEDS in CW mode, COMPASS with 8 minute intervals and decoded telemetry from CUTE in CW mode. 73 de David VK5DG

145 MHz IF on mode V/s
by K & R Yoksh 21 May '08

21 May '08

Hello all, Thanks for the many replies to my question. There were a couple with quite a lot of detail. I'll likely just go with the AIDC 3731 with 145 MHz IF mounted at the dish. I don't know the noise figure of my 123 MHz units. I needed a 145 MHz IF in the AO-40 days, as I discovered that an original Icom 706 (mkI) has lousy sensitivity at 123 MHz. I've since upgraded to twin 706MK2g rigs that hear just fine at 123.. BTW, anyone have a ballpark idea of when P3E will launch? Last I heard was late 2008? 73, Kyle Yoksh K0KN Olathe, Kansas

QSL's to Canada and Mexico
by Ronald Nutter 21 May '08

I am trying to get VUCC and have made several contacts in Canada and Mexico. In trying to be courteous, I dont just want to drop the cards in the mail and hope that I get a return. I would like to get local postage so they can put the card in the mail and get it back to me with no cost to them. I have found a link to the Canadian post office and am waiting for a login to the website so I can order stamps. The Mexican post office doesnt seem to be as organized in the same way. There isnt a english page on the site and google translating only gets you so far. What are my options with getting postage to Mexico ? Ron KA4KYI

Cute-1.7 : FM Packets All Over the World !
by Hiroki Ashida 21 May '08

21 May '08

Dear All, I'm Hiroki Ashida at Tokyo Institute of Technology (JQ1YCZ) and I'd like to inform you about our satellite's operation which starts very soon. We're preparing for a long-run (continuous 12hour) of the APD (avalanche photo-diode) carried on Cute1.7 + APD II, as a radiation monitor of low-energy (E> 10 keV) particles trapped in the LEO (low Earth orbit). While the APD is operating, the status packet of APD is transmitted every 16seconds (TBD). The observation will start at 10:40, May 21 (UTC) and the APD will be turned off on 22:40, May 21(UTC). So the APD packet can be received everywhere in the world! This is the first time that Cute-1.7 + APD II transmits its FM packet around the globe. Though the observation data will be stored in FRAMs, we'd like to know a real-time status of the APD during the observation. Your kind reports will be highly appreciated. FM packets are transmitted on 437.475MHz and packet formats are available in the following web-page. http://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html 4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A-D0-30-77-B8-03-16-99 For exapmle, according to an above APD status packet we can obtain informations as; 4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A : Header(JQ1YTC>JQ1YCZ) D0 : APD Packet ID (Fixed) 30 : Status Code APD Status : Operational HV Status : Set Value = Output Value Temp Correction : Active Data Mode : Counter Valid Detector : APD A APD Gain : Gain 30 Threshold : 219mV 77 : Temperature 0x77 = 119 -> (119/255)*91.712-48.569 = -5.7 [degC] B8 : High Voltage 0xB8 = 184 -> (184/255)*396.5 = 286 [V] 03-16-99 : Counter 0x1699 = 5785 -> 5785 * 2^3 = 46280 Latest TLE from NORAD is; Cute-1.7 + APD II 1 32785U 08021C 08140.34460534 +.00000335 +00000-0 +49764-4 0 00590 2 32785 097.9939 200.3316 0014139 226.7351 133.2682 14.81357711003132 Best Regards, Hiroki Ashida Cute-1.7 + APD II -- Hiroki Ashida <hiroki(a)lss.mes.titech.ac.jp> Laboratory for Space Systems Department of Mechano-Aerospace Engineering Tokyo Institute of Technology TEL/FAX : +81-3-5734-2644 Room 554, Ishikawadai 1st Bldg, Tokyo Institute of Technology 2-12-1 O-okayama, Meguro-ku, Tokyo, Japan

Re: AOP-1 Circular Polarization?
by Ronald G. Parsons 20 May '08

20 May '08

Assuming the antennas you reference do produce circular polarization, radiation wise, it doesn't matter whether you mount them in an X or + orientation. The only difference would be the phase of the radiation, and you are not concerned with that. There could also be a difference between right- or left-circular polarization, but whether that matters depends on the polarization the the satellite's antenna. But X or + does not change that. There might be some mechanical reason for an X or +, such as weather proofing, but not signal wise.

Re: Status on AO-16?
by Mark L. Hammond 19 May '08

19 May '08

Hi Mike, Indeed, over the last several days you are likely to have found AO-16 silent. There appears to be something in the spacecraft shutting down the transmitter after a short, random period of time. Current speculation on the problem includes a temperature issue that has reared its ugly head now that the eclipse periods are increasing and the spacecraft internal temperatures are decreasing. It may be a hardware timer. It does not appear to be a battery issue. At this point, the best we can do is to manually turn the satellite ON and then configure it for voice operations. This is a manual process and command stations are limited to the East coast of the US. As our busy schedules permit, we'll try to turn it ON; for now, it's the best we can do. Only time will tell if the current situation will stay the same, improve, or get worse. 73, Mark Hammond, N8MH AO-16 Command Station >Can anyone tell me the status of AO-16?

New rig ... SSB birds
by Garie Halstead K8KFJ 19 May '08

19 May '08

I just purchased a new FT-817ND and plan to use it in conjunction with my existing IC706MK2G. The plan being to perhaps work some SSB. I wondered how much operation there is right now on VO-52 for instance. So, I picked a midday pass with some excellent elevation for my activity test today. At TCA, I still had not heard anything on the new 817. That was my fear ... inactivity. I was beginning to give up when suddenly Chip (W4PBG) in FM19 calls CQ and hooks up with Don (K5BTK) IN EM42. The mode was CW. I guess that answered any question I may have had regarding activity. I hope to be on the bird soon with the new setup. Sounds as if an op could be fairly busy just dealing with the Doppler aspect while sending, copying, etc. Can someone guide me to a tutorial perhaps. Many thanks. 73, Gary -K8KFJ- West Virginia (EM98) AMSAT #32574 Sat VUCC #125

145 MHz IF on V/s?
by K & R Yoksh 19 May '08

19 May '08

Hi all, Thanks for the replies, however, I've still not had my question answered, so I'll ask again. I'd like to hear from anyone using a 145 MHz IF when working mode V/s. Do you experience desense when operating V/s, but not other uplink modes? I'm planning to use my AIDC 3731 with 145 MHz IF when I install my dish this summer. I really want to use it for HEO operation, but it'd be a bonus if I could also work the LEOs. I could go with a 123 MHz IF unit if that'd work better. Thanks and 73, Kyle Yoksh K0KN Olathe, Kansas

I'm just being cautious with my FT 736R before I try this, so, if I use my Downeast Microwave 2400 - 144 downconverter which puts the S band downconverter downlink at around 145.2 MHz and I operate the uplink at around 145.9 MHz, this separation of 700 KHz won't blast (desense) my receiver front end or the downconverter? I'm using anywhere from 2 to 10 Watts on the uplink and SATPC32. Thanks Ron N6PAA **************Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.

Delfi-C3 status update 18 May 13:00 UTC
by Wouter Jan Ubbels 18 May '08

18 May '08

Hi all, Another status update on the Delfi-C3 satellite: 1. During the 10:40 UTC pass over the Delfi-C3 groundstation on Thursday 15th of May, the linear transponder was successfully tested and activated for a short time. The CW beacon was received well and subsequently good signals using SSB were received. An audio file of the test can be found at: http://www.delfic3.nl/photoblog/wp-content/uploads/2008/05/pe4wj_transponde… 2. We are currently performing tests while the spacecraft is over our groundstation in order to address the downlink dropout issue. Since we take it step by step, the satellite may still experience downlink dropouts over the coming days. 3. TLE's for object G match best at this moment, we are becoming more and more confident that G is in fact Delfi-C3. 4. Up to this date, we have received over 130000 AX.25 frames from all over the world, thank you very much for your efforts and observations so far! 5. Delfi-C3 has been given an OSCAR number by AMSAT, and is now Also Known As DO-64, which stands for Delfi-C3 OSCAR 64 or Dutch OSCAR 64. It is a true honour for all team members to have Delfi-C3 join in the long tradition of OSCAR satellites. best 73, on behalf of the Delfi-C3 team, Wouter Jan Ubbels PE4WJ

CUSat Ham Radio Update
by Albert Ren 18 May '08

18 May '08

Hi all, Several weeks ago, Nate Parsons sent you all an email requesting assistance with our antenna setup on the satellite and ground stations. I just wanted to express our thanks and appreciation for all the help and advice that everyone provided to us, as it was very helpful and got us back on track. It's been a little while since that flurry of activity, so I thought I'd give you an update on how things have progressed since then. Because of the schedule and program constraints, we had to settle on a commercial-off-the-shelf solution for our space segment design. The antenna we ended up choosing was the Comet SMA-503 antenna. In a ridge test out at Cornell, the results were much improved over the previous square-loop antenna design. In case anyone was wondering, the coating on the antenna is very easy to remove, but the base of the antenna should be left alone as that contains a matching circuit and is structurally necessary. We also had the fortunate circumstance of a patch antenna becoming available to us, but unfortunately this design is too large to integrate onto the satellite. On the ground station side, we've replaced the in-shack pre-amp that we had with a mast-mounted pre-amp that we bought from SSB. We have one ground station fully assembled at Kwajalein in the Marshall Islands. The next big hurdle on that front is the software that we need to control the ground station. We've decided to write our own antenna tracking software, taking advantage of the fact that our ground station is essentially at the same location as the launch site. Currently, the antenna is undergoing final testing at the AEF down at Kirtland. We hope to ship the satellite out by the end of the next weekend in order to meet the schedule for the SpaceX launch, should we become the chosen payload. Again, thanks for all your help! Please let us know if you have any questions or any other suggestions - we appreciate it all. We'll also keep you updated of any changes or news from the program. Regards, Albert Ren CUSat Ground Segment Lead

AOP-1 Circular Polarization?

18 May '08

Hello all, I'm getting ready to put back up my old AOP-1 antennas (the old Cushcraft antennas that were popular in the days of AO-10 & 13). I'm wondering whether I should follow the same procedure of cross polarization for the 440 beam? It was recommended at the time to place the antenna in an X pattern instead of the cross pattern. Also, at the time, the 2 meter antenna was suggested to be placed in the standard vertical/horizontal polarization.

May 18, 2008 To All RADIO AMATEURS BID: $ANS-138.01 Team Namaste, a new AMSAT engineering team, was introduced at the Dayton Hamvention held over May 16-18. AMSAT's Eagle and the Intelsat Phase IV ride-share project will include the Advanced Communications Package (ACP) supporting digital communications with a 5.6 GHz uplink and 3.4 GHz downlink. Team Namaste includes the ACP Ground Segment led by Michelle, W5NYV and the ACP Satellite Segment led by Matt, N2MJI. Michelle described the ground segment, "Namaste is the effort to develop a microwave band, digital signal capable earth station attainable by the average ham so users can immediately take advantage of the audio, digital messaging, and video services our new new sat- ellites will provide." Two key user audiences are the target of the Namaste earth station. Michelle describes the user base, "First we want to excite amateur radio operators who want to have fun using microwave bands to talk through a satellite employing digital communications techniques. Second, we want to serve emergency communications operators who need a reliable, infrastructure-independent system in order to get their work done." The Ground Segment and Satellite Segment Teams are developing an RF link budget and system configuration which a reasonably priced ama- teur radio transceiver can attain. No commercial amateur radio gear exists for the GHz-frequency range and digital communication link for the new mode on AMSAT high orbit satellites. Antenna configuration and available power are limited on the satellite platform depending upon solar cells and batteries. Given the modern reality of CC&R's and antenna restrictions in many communities the baseline antenna at the amateur station is currently specified as a half-meter dish. This is the same type and size of dish many homes use for satellite television such as DirecTV. Planning for the ACP includes 20 watts RF power with 18dB antenna gain at the spacecraft. The ground segment rule of thumb at present esti- mates 10 watts of transmitter power with the half-meter dish is needed. Further radio link budget and RF exposure safety issues are also being investigated. AMSAT welcomes Team Namaste, leading the way to an exciting future of Amateur Radio in Space. Questions and comments can be sent via e-mail to namaste-dev(a)amsat.org. Team Namaste has a web page at: http://www.amsat.org/namaste.

May 18, 2008 To All RADIO AMATEURS BID: $ANS-138.02 Bill Tynan, W3XO issued the following statement on behalf of the AMSAT Board of Directors this week: By the authority vested in me by the AMSAT-NA President, I am pleased to issue an OSCAR number for the amateur radio satellite, Delfi C-3. As attested to in a communication to the AMSAT-NA Board of Directors dated 8 May, 2008, from Wolter Jan Ubbels, the spacecraft's Project Manager; Delfi C-3 was successfully launched 28 April, 2008 from India aboard a Polar launch vehicle. Mr. Ubbels also states that the satellite was successfully commissioned and is currently transmitting telemetry on the 2 meter amateur band. In addition to its 2 meter downlink, Delfi C-3 has an uplink on the 70 cm band. According to Mr. Ubbels, this newest amateur satellite was developed by a team of some 60 students and facility members in the fields of Aerospace Engineering, Electrical Engineering, Mathematics and Computer Science from various polytechnic schools in The Netherlands. Further, he states that Delfi C-3 carries 2 experiments, one involving thin film solar cells developed by Dutch Space and the other, an Autonomous Wire- less Sun Sensor from the Dutch Government Research Institute (TNO). Mr. Ubbels' letter says that Delfi C-3 has been duly coordinated through the Region 1 IARU representative, Mr. Graham Shirville, G3VZV, and that the satellite meets all of the criteria necessary to be issued an OSCAR number. In response to the information provided by Mr. Ubbels, I hereby issue the designation Delfi-C3 OSCAR-64 or Dutch OSCAR-64. The shortened ver- sion of either of these two designation would, of course, be, DO-64. AMSAT-NA is pleased to welcome DO-64 into the family of amateur Radio satellites. We are hopeful that it will fulfill its intended mission of furthering education and increasing interest in the Amateur Radio space program. We congratulate all of those responsible for designing, building, testing and launching this new Amateur Radio satellite and look forward to its long and productive life. 73, William A. (Bill) Tynan, W3XO [ANS thanks Bill, W3XO for the above information] /EX SB SAT @ AMSAT $ANS-138.03 AMSAT at Dayton - First Report AMSAT News Service Bulletin 138.03 >From AMSAT HQ SILVER SPRING, MD. May 18, 2008 To All RADIO AMATEURS BID: $ANS-138.03 The AMSAT booth at the Dayton Hamvention included the first stages of the full-scale engineering unit of the Eagle satellite structure. This consists of the inner 4 honeycomb panels where electronics are mounted, along with four channels and two electronics boxes. The half- scale model of Eagle was also on display. After the Hamvention the Eagle engineering unit will return to the AMSAT Maryland Lab for further development, integration, and testing. Radio amateurs were able to get a taste of satellite operations at the live satellite demos. Using the callsign W5IU the demo team was on-the-air via AO-7, AO-16, AO-27, AO-51, and VO-52 on Friday, Sat- urday, and Sunday. Tom Clark, K3IO gave a presentation discussing the highlights of AMSAT's technical achievement and plans at the ARRL TTF Forum. The AMSAT forum provided updates on Eagle and Intelsat. More information will be coming in future weeks via ANS and the AMSAT Journal. AMSAT Engineering representatives were on hand to show off and discuss project status for the ACP, Eagle, Phase IV, P3E, SuitSat-2, and dig- ital encoding. The combined AMSAT/TAPR Banquet was one of the more popular events of the weekend. Pictures and more stories to follow when they are ready. The Spring 2008 issue of CQ-VHF magazine, planned to be available at the Hamvention, featured AMSAT in three articles. Lou W5DID & JoAnne K9JKM had an article covering SuitSat-2. Bob KF4KSS & JC W3JCT had an article about AMSAT's new lab, and Keith W5IU wrote a column of amateur radio in space history and AMSAT's history.

May 18, 2008 To All RADIO AMATEURS BID: $ANS-138.04 The AO-16 satellite has undergone a few periods of turning off with subsequent restarts ensuring operation for varying periods of time. Mark, N8MH, Control Operator turned AO-16 ON in voice mode to suppot a Scouting Special Events Station. The output power was reduced slight- ly in an attempt to conserve power in the event that batteries or the solar cells were having problems. George, KA3HSW, operating from the Scouting Event wrote, "Many thanks to Mark for making AO-16 available during the K9BSA Scout-O-Rama demonstration yesterday, and MANY, MANY thanks for "advertising" that our station was there on the 1950Z pass... we worked quite a number of stations, thanks in large part to Mark's announcement on the bird." In response to observing stations around the world reporting AO-16 was turned off again Mark provided the latest information, "AO-16 continues to exhibit difficulty in keeping the transmitter turned ON. The last few days I have turned it ON as my schedule permits, only to see it turn itself OFF after a short time (sometimes minutes, other times a few hours). So, it hasn't been turned ON much over the last several days. It is looking less likely to be a power budget issue, and more likely that there is something going on with the hardware in the spacecraft; but this is still speculation. Time will tell. I wish the news was better!" If you hear AO-16 in voice mode, free to use it. If you hear it "hummmming" in digital mode, please do not transmit to the satellite.

Upcoming School Contact Delta Researchers Schools 2008, Space Expo in Noordwijk, the Netherlands, has been scheduled for an ARISS contact via tele- bridge station WH6PN in Hawaii. The contact will take place on Friday, May 23 at 15:01 UTC. Twelve Dutch primary schools which participate in the Delta-project will be represented at Space Expo. The project is a cooperation of the Dutch ministry of Education, Culture and Science, the European Space Agency (ESA) and NASA. The schools participating in the project use the themes of space and space exploration to teach science and technology. Three chil- dren (ages 7 - 12) from each school will be present. 2. Armada Area Schools - ARISS Contact Postponed The ARISS contact which was scheduled with Armada area schools in Michigan on May 9 was postponed due to crew scheduling issues. It will be rescheduled in the fall. In place of the May 9 contact, the Teaching From Space Office at Johnson Space Center arranged a tele- conference between the Armada students and astronaut Bill McArthur in Houston Texas. Bill spent several minutes talking about the Inter- national Space Station and answered in detail 15 student questions. There were approximately 550 participants present at the school. The Teaching From Space Office also sent an educational resource package to the school which included seeds that were flown in space. The Armada schools are looking forward to a direct ARISS contact in the fall. 3. ARISS Founder Ron Parise Passes on Astronaut Ron Parise, WA4SIR, passed away on Friday, May 9. Ron was a key player in the development of the ARISS program and a strong supporter of educational outreach activities. He spoke with hundreds of hams on the ground during his Shuttle flights STS-35 and STS-67 and was the first to operate packet radio in orbit. He was instrumental in developing both the ISS Ham radio systems currently onboard the ISS and the telebridge station concept with the specific purpose of encour- aging students to pursue studies in technical fields.

[AMSAT-BB] 145 MHz IF on V/s?

----- Original Message ----- Message: 10 Date: Fri, 16 May 2008 11:52:19 -0400 From: WB2LLP <wb2llp(a)optonline.net> Subject: [amsat-bb] AO-40 DUH To: AMSAT -BB <AMSAT-BB(a)AMSAT.ORG> Message-ID: <006b01c8b76c$d28bd6f0$6401a8c0@gene> Content-Type: text/plain; charset=iso-8859-1 Thank you for the responses. The answer should have been obvious since I was using my IC-821 to work through AO-40. To make it worse, I have a couple of other rigs which have the 2M band. The next time we have a V/S configuration I shall try to overcome my senior moment. Gene WB2LLP Hello Gene (and the list), Your question reminds me of a question I've been meaning to ask! My current S-band antenna is a simple integrated antenna/downconverter with 123 MHz IF, but I plan to install a P3E-ready dish and downconverter on my crossboom this summer. My best downconverter is a K5GNA unit with 145 MHz IF. I wonder how it'll play on mode V/s? Can anyone comment on this? I also have some more 123 MHz IF units, but their NF is unknown. I'd rather use my AIDC 3731 from K5GNA, even if it means reduced performance on V/s. I plan to optimize for HEO operation, but I'd be happy if I could also work AO-51 in mode V/s. Thanks for any help or advice! 73, Kyle K0KN

Kind of Sad
by Frank H. Bauer 17 May '08

17 May '08

I have been an AMSAT-NA member since the early 1982. I have volunteered extensively for this organization. And have led several key projects. Despite the negativism I have seen lately, I am still VERY PROUD of this team and organization. It is not perfect.no organization is. But if you look at our history, we have done some pretty darn amazing things for a volunteer organization---past and present. What I find sad are those on amsat-bb that constantly bash AMSAT-NA. They provide no help (money or time). And only THEY are right. Are we all that short sighted?? I hope not. We are still doing some pretty amazing things. And we have some great projects that need three major items to be successful: 1) Money 2) YOUR volunteer time and 3) Some additional leaders to bring these projects to fruition. So let's stop the petty bickering. That is too easy. Let's do the hard stuff..lead by volunteering your time and talent ..and let's build some vehicles that fly in space! 73, Frank H. Bauer, KA3HDO AMSAT-NA V.P. for Human Spaceflight Programs P.S. Responses to this should be e-mailed directly to me..no more bickering on -bb please!

Could someone please help me on the following as I am still having problem to copy SEEDS packets. 1. I tried MixW2, TNC emulation, N8VB com port redirector, and Tunaterm. Tunaterm successfully decodes a bunch of Binary data, but because MixW2 is emulating a KISS TNC instead of a normal TNC, I am not sure if the data is accurate. 2. I tried also KPC-3+ in KISS and non-kiss mode directly with Tunaterm. Unfortunately Tunaterm did not successfully decode any packets except for one or two. I believe the SEEDS packet were standard AX.25 1200 baud packets? Could someone kindly guide me to the right path. Thank you very much in advance. 73, Sion Chow Q.

Operating from North Scotland
by Ivo Klinkert, PA1IVO 17 May '08

17 May '08

Hello, >From 20-31 May I will be on holiday in North Scotland, and I take some amateur radio equipment with me. I will be QRV on LEO voice sats, AO-51 (on the second repeater when available), SO-50, VO-52 and possibly AO-16. My callsign seems to become MM/PA1IVO/P. For detailed information, query PA1IVO on QRZ.COM. There will also be some 'mutual visibility' between North Scotland and Canada in those days, which is probably not achievable with a portable setup, but I will see what a set of FT-817s is capable of ;-). 73, Ivo, PA1IVO

DO-64 not heard; SEEDS/COMPASS-1/CUTE all ok
by David 16 May '08

16 May '08

Hello All, A couple of reports of the latest cubesats. Yesterday morning's pass (2008/05/16/00:05 UTC) netted CUTE1.7+APD II - heard, recorded, decoded and sent telemetry COMPASS-1 - heard three times during CUTE pass, must be on 3 min timer DO-64 (Delfi) - not heard on either beacon frequency Today's morning pass (2008/05/16/22:52 UTC) netted CUTE1.7+APDII - heard COMPASS-1 - heard SEEDS - heard in CW mode, recorded and telemetry will be sent DO-64 - still not heard. So in around 20 attempts, I have only heard DO-64 twice and able to decode packets once. It's still turning off before it gets to the southern hemisphere. 73 de David VK5DG

WD9EWK from DM32/DM42 tonight (0144-0211 UTC, 17 May)
by Patrick STODDARD (WD9EWK/VA7EWK) 16 May '08

16 May '08

Hi! Later today, I will drive to a spot 50 miles/80km or so south of downtown Phoenix in Pinal County for a couple of satellite passes. I will park on the DM32/DM42 grid boundary (112 degrees West) down there in time for an AO-51 pass immediately followed by an SO-50 pass. Both passes go to the east of that location, and the footprints will cover much of North America. I will be on the AO-51 pass at 0144 UTC, followed by the SO-50 pass around 0158 UTC. I will switch over to SO-50 once I'm not able to hear or work AO-51, since those two passes have a slight overlap around 0158-0159 UTC in that area. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Thank you for the responses. The answer should have been obvious since I was using my IC-821 to work through AO-40. To make it worse, I have a couple of other rigs which have the 2M band. The next time we have a V/S configuration I shall try to overcome my senior moment. Gene WB2LLP

AO-40 S band
by WB2LLP 16 May '08

16 May '08

I was going to set up to receive AO-51 on VS when it occurred to me that I need the 144 band as the receiver for the S band down-converter. Then I remembered that I used to have QSOs on AO-40 with the same gear that I still have, but I do not remember and can not find any notes as what band we used for the uplink. Will someone with a better memory/set of notes please remind me what band we used for the uplink? TNX es 73 de WB2LLP

trade-secret, patented, copyrighted nature of the AMBE voice codec used in the D*STAR

Not sure if you folks have seen this recently. It has a reference to AMSAT in the draft: http://codec2.org/ and the referring article: http://technocrat.net/d/2008/5/14/41380 Also, regarding the LEOs, I really enjoyed using them and only found them to be busy on weekends and at night, but I wouldn't say they were hard to use. Plus, for someone who doesn't have the expensive HF gear, it was my only way to get into exchanging QSL cards using N2SPI's homebrewed antennas that I got from AMSAT's website. 73, -Rob

Re: Organised Chaos.

Dave, It is obvious that there is a whole generation of Leo-FM sat users that are clueless of what ham radio on a Heo linear-tranponder is like. Although it must be harder than a cell phone since so many cannot seem to figure out how to operate on the Leos...I would say it is not "much" harder than using the local repeater. I offer an analogy: Compare all the ham radio contacts that are done on HF with the same number of folks trying to talk thru a single FM repeater! First it cannot be done; second the attempt results in total chaos with "big fish" eating the little fishes! I am waiting for the next Heo and hoping it survives better than the last one. 73 Ed - KL7UW At 12:31 PM 5/14/2008, Dave Guimont wrote: >John, the operation of FM voice satellites is a travesty for ham radio... > >I've been licensed for 57 years, on amateur satellites for 33 years >(Oscar 7) and the FM voice operation is the most ridiculous >aberration I've witnessed in all of amateur radio...Pandemonium >exists here also!! > >It is pretty obvious NO COMMUNICATION exists on AO51, >all of their communication is on here.

SEEDS packet
by Robert Turlington 15 May '08

15 May '08

Hi All today at about 1220utc SEEDS was sending a packet sounding audio,I tried to decode using MixW but the audio tones didn't quite match anything ,they were about 1100hz/2300hz.Next time I hear them I will try and get an accurate value. The question:-is there any sound card software out there that can decode,its posible that I can use a similar method to UO11 decode using MixW ,I will have to see.Regards Robert G8ATE _________________________________________________________________ Discover and Win with Live Search http://clk.atdmt.com/UKM/go/msnnkmgl0010000007ukm/direct/01/

I can assure you it definitely is. If you have read my 'road trip' posts, then you would know that i do have alot of experience in mode J-FM. We have occasional problem with people calling CQ who can't hear the satellite and there is some unnecessary QRM from people who can't hear their own downlink (e.g. are not operating full-duplex). But it is quite workable much of the time, especially on weekdays. My biggest frustration out here is when alot of the satellite time is taken up with the 'regulars' saying hello to the same people, week after week. Weekends, particularly on AO-51 and often on AO-27, can get pretty chaotic. My experience on my trip from California to Colorado/New Mexico was that it seemed to get somewhat worse as i went east. So i would say it has to do with the population density in the footprint of the satellite. Yet on the quieter passes on that trip, several times i sent a quick message home third-party via satellite where i would be camping for the night when there was no cell phone coverage or pay phones available. Amateur radio works when nothing else will. Before i say alot more on why i think there might be such a difference between operating in the United States and in western Europe, i need to transcribe my satellite passes when i visited Paris last year. I've procrastinated doing this simply because i don't think i had more than one or two QSOs worthy of a QSL card out of 7 passes attempted while i was over there this time. I did do better in 2005 with two successful QSOs in 4 passes from southern France. In North America, Mode J-FM is quite workable if what you are looking for is a QSL card. It is also good for amateur satellite demonstrations, as almost always, there will be someone to talk to. Please use a linear transponder if you want to have an extended QSO when a satellite covers well-populated areas. While Mode J-FM can be very frustrating at times, if you're looking for VUCC or Worked All States on satellite, clearly it is the best way to go in North America. -- KD6PAG P.S. Except on SO-50 when i'm on the road, all contacts referenced above were made at 1W or less. So power is not necessarily a factor. P.P.S. Addendum to my Portland trip report, W6ASL received 17 grid squares out of 19 activated. Good work, Jim.

Is there any possibility that one of the major manufacturers will introduce a new satellite rig in Dayton? Or that the mail order houses will have special prices for those who can't attend Dayton? Is that a common practice? I'd like to thank everyone on here who replied when I mentioned that I was starting back up on satellites. Your suggestions have pretty much convinced me that I should go with the Kenwood TS-2000. So if anyone strongly thinks that I shouldn't, please express your thoughts on this. 73 de W4AS

"Birdies" from Linksys Wireless router
by Mark L. Hammond 15 May '08

15 May '08

Hello all, The launch of Delfi-C3 has brought to my attention a very strong birdie at 145.930 MHz that clearly comes from the Linksys WRT54G Wireless router that sits in the shack. Forcing the wireless signal to another frequency/channel has no impact whatsoever... Anybody on the list have a clever solution (other than 'get a different router' or 'move it' or 'shut it off', etc...hi hi) that they may have used for a similar problem? Thanks, Mark L.

Organised Chaos.
by John Hackett 15 May '08

15 May '08

In 17 years of satellite operating - and literally thousands of QSO's, I'm proud of the fact that I have actually had 2 - (that's two, folks) - QSO's on FM. I believe the last one was W3SM/OE on AO-27 about 10 years ago. For want of something better to do today I went outside with my arrow aerial, a MYCOM handheld scanner and a little IC-E91 (also handheld) to have a listen to AO-51 ... (I've heard it described as a "zoo"). I monitored the 16:15Z pass over Russia/LA/Europe/UK and what I heard can only be described as the worst operating I've heard in 41 years of radio. There were stations battling it out with the mine's bigger than yours mentality, stations "hogging" it, constantly calling CQ, CQ, CQ, CQ, CQ, CQ, CQ, CQ, CQ, CQ ... pause for breath ... CQ, CQ, CQ, CQ, CQ, CQ, CQ, CQ, CQ ... (no callsign given but obviously a Russian station), Several stations replied to this gentleman but he was obviously *NOT* hearing them. There was the 'obligatory' awwwwwla, awwwwwla, awwwwwla, awwwwwwla - (the mic-shy gentleman who can't find his downlink). (Don't these clowns have receivers ??.....LA2QAA) AO-51, what a wonderful resource for showing the non-amateur listeners that these operators are fully competant to operate an emergency network like the one mentioned planned for Intelsat. I'm absolutely convinced !!! Intelsat will welcome such operating with open arms!. My (non-amateur) neighbour's immediate comment was - "I'm glad my !!! life doesn't depend on you lot, it sounds like a fox loose in a henhouse". I'm ashamed to say, I absolutely agree with him. I also sincerely hope that the standard of operating (read: disipline/ proceedure) is better in North America than it is in Europe - actually, I've listened via N1DID and Echolink, as well as the promo video so I know it is. 73 John. <la2qaa(a)hotmail.com>

You can use any oscillator module, such as from an old PC motherboard, that will put out harmonics up in the 2.4 GHz range. I happened to find a 24.000 MHz one on an old MB. Just now, looking around in the junk drawer, I found ones for 4.000 and 16.000 MHz as well.

Finding Folks at Dayton
by Robert Bruninga 14 May '08

14 May '08

You don't need GPS for finding folks at Dayton Unless you are lost and cannot read a map. I have prepared 3 maps of the Dayton Buildings and Flea Market area that have LAT/LONG coordinates on them. Just manually enter your coordinates for your space or booth or present location into your D7 and then your radio will tell you which direction and how far anyone else is... Indoors, the maps work fine (GPS doesn't). Even at 60 foot resolution, there are 75 discrete locations inside. In the flea market, there ar 650 sets of coordinates to help you find anyone. It also helps if you key in your space or booth number into your text for the final few feet... To find someone, enter your manual position into your D7, then your radio will tell you which direction and how far away they are! Or look at their coordinates on the these gridded maps: http://www.ew.usna.edu/~bruninga/aprs/Dayton-inside-map.GIF http://www.ew.usna.edu/~bruninga/aprs/Dayton-flea-east.GIF http://www.ew.usna.edu/~bruninga/aprs/Dayton-flea-west.GIF Bob, WB4APR

Unfortunately, I had no success with the AO-51 V/S mode this past week. Before the next V/S mode operation comes around, I want to double check performance of my antenna and downconverter. Some of the folks in the UK had these items available during AO-40 days but don't think they're available today, such as: _http://www.uk.amsat.org/index.php?option=com_content&task=view&id=252&Item… 86_ (http://www.uk.amsat.org/index.php?option=com_content&task=view&id=252&Itemi…) I've seen Bob's K5GNA 2.4GHz Source on eBay with the: _http://cgi.ebay.com/2-4-GHz-SIGNAL-SOURCE-GARDINER-TYPE-LO2398-AMSAT_W0QQi… Z110251114382QQcmdZViewItem_ (http://cgi.ebay.com/2-4-GHz-SIGNAL-SOURCE-GARDINER-TYPE-LO2398-AMSAT_W0QQit…) Are there other small modular type 2.4Ghz Sources out there that I can use to verify downlink setup?

Hello Pedro, Thank you for your question. AO-16 continues to exhibit difficulty in keeping the transmitter turned ON. The last few days I have turned it ON as my schedule permits, only to see it turn itself OFF after a short time (sometimes minutes, other times a few hours). So, it hasn't been turned ON much over the last several days. It is looking less likely to be a power budget issue, and more likely that there is something going on with the hardware in the spacecraft; but this is still speculation. Time will tell. I wish the news was better! 73, -- Mark L.

Re: ao-27?

I am still baffled as to why this is happening... the clock on the AO-27 website agrees with my PC clock, we are both using the same EPOCH.TXT and TOPR.TXT files, and yet the website is somehow calculating different event times than my son's program (which, as you said, appears to be calculating the correct times). I just checked now, and at this moment, the website is behind by just over 5 minutes... I should try to get in touch with Mike Wyrick and see if he can tweak something over there at ao27.org.

Re: Suggestions for Mode L antenna
by Edward Cole 13 May '08

13 May '08

Bob, Ron and Greg: The problem we have at this point is that uplink and downlink performance has not been specified by the P3E team. So, in my thinking, one can only go with the AO-40 experience for making enigneering decisions for your ground station. On SSB I found that 9.5w and 20-dBi (linear pol) was inadequate for AO-40. It looked to me that I needed a minimum of 15w and more would have been better. This is power at the antenna terminal not at the radio, so one has to calculate line loss. For operating the Leos your uplink needs are probably less and I will leave it to experienced operators to state what that is. Fortunately, Times Microwave gives you a wonderful on-line cable-loss calculator for their entire line of cables: http://www.timesmicrowave.com/cgi-bin/calculate.pl or you can download the zipped program to run on your local computer: http://www.timesmicrowave.com/cable_calculators/ Plugging in LMR-400 x 50-feet at 1268-MHz results in 2.3 dB line loss or 58.3% power at the antenna. Using my AO-40 requirement of ERP = 15w x 100 = 1500w: One would want 25w at the radio end of the 50-foot cable. Bob has this easily with his KJ6KO 60w amp with over 3-dB spare. BTW my current 1296 setup uses 150-feet of 7/8 hardline with ~20 feet LMR-400 to give me 20w at the antenna (I have a KJ6KO amp as well). For satellite, I will probably mount my 15w 144/1268 Tx converter at the antenna, thus eliminating expensive hardline. I do that for my 435-MHz uplink by using a 50w brick at the satellite tower and using 125-foot of RG-213 to provide an input of 12w from my FT-847(50w). I have an outside equipment box with 12-v power supply and room for preamps and coax relays: http://www.kl7uw.com/sat.htm Bob, you might be OK with a 16-dBic Helix considering the power you have. A 4-foot dish is equivalent in gain to a 12-foot long Loop Yagi (20-dBi) and much harder to mount and aim, so my recommedation would be using yagis to get the gain (and be easier on your az-el mount). If I recall the M2 yagi has that. Don't forget that you gain a 3-dB advantage when using a CP antenna on Mode-L. If you are going to use the dish for 2.4-GHz reception then dual-band use might be an advantage. With Ron's 10w in the shack he will only have about 5.8w at the antenna, so you may need more gain. For P3E this is most likely; for AO-51 that might be OK. In any case I would recommend LMR-400, at minimum, as low-loss cable, or placing a brick amp at the antenna to boost up your power. Note: Dale-KL7XJ runs 10w on 1268 to a helical beam on AO-51 so, without knowing his line loss, one might guess that 50-feet LMR-400 + Helix will be adequate on AO-51. 73 Ed - KL7UW At 11:15 AM 5/12/2008, w7lrd(a)comcast.net wrote: >Hello >Currently the way I have been doing L band is as follows.

Delfi C3: spin rate unchanged in the past 2 weeks
by Henk, PA3GUO 13 May '08

13 May '08

Dear all, Based on my simplistic experiment of yesterday, May 12th, I would say that after the first two weeks in space the spin rate / rotation of Delfi C3 has not changed much (read: reduced). At least, due to the multiple variations it's difficult for me to observe a significant change already. Here is the graph of May 12th: http://home.vianetworks.nl/users/hamoen/pa3guo/dc3_12may08_2045utc_pa3guo_s… Here is the graph of April 29th: http://home.vianetworks.nl/users/hamoen/pa3guo/dc3_29apr2008_pa3guo_rotatio… Henk, PA3GUO http://www.qsl.net/pa3guo

Re: Suggestions for Mode L antenna
by Greg D. 13 May '08

13 May '08

Hi Ron, I built the helix because they are fairly tolerant of slight differences in materials and assembly dimensions. I am by no means a precision builder, so this seemed right for me. I have an ICOM 1271A in the shack, which is supposed to put out about 10 watts. This goes to about 5 feet of RG-214 (I think - it's the 50 ohm stuff that looks like RG-8, but has better shielding), to a box outside where there's supposed to be a lightning arrestor. That's on my list of things-to-buy-soon... Right now the arrester is just an N-N barrel connector. That feeds about 60' of Andrew hardline (LDF4-50A) up to the roof, where there is another barrel connector and another about 5' of that RG-214 to go around the antenna rotor to the antenna itself. At 1.2 ghz and 50-odd feet, I expect that hardline is going to be a requirement. Or you could mount a power amp and pre-amp at the other end of the coax, along with power and sequencing logic. The hardline I got was a trade from another ham who worked, I'm guessing, in the CATV, Telephone, or similar industry. I got something like 180 feet of it in trade for a short 70cm antenna, enough for 3 runs to the roof. There was a bit of a kink in the middle, so that run is on a lower band :-). Ask around, you might be able to scrounge up something. Good luck, Greg KO6TH ---------------------------------------- > Date: Mon, 12 May 2008 07:50:44 -0500 > From: rnutter(a)networkref.com > To: ko6th_greg(a)hotmail.com > CC: amsat-bb(a)amsat.org > Subject: Re: [amsat-bb] Re: Suggestions for Mode L antenna > > Greg: > > Thanks for your option.
