SpaceX statement on flight 3 anomaly
by Lee McLamb 03 Aug '08

03 Aug '08

Plan Going Forward It was obviously a big disappointment not to reach orbit on this flight [Falcon 1, Flight 3]. On the plus side, the flight of our first stage, with the new Merlin 1C engine that will be used in Falcon 9, was picture perfect. Unfortunately, a problem occurred with stage separation, causing the stages to be held together. This is under investigation and I will send out a note as soon as we understand exactly what happened. The most important message I’d like to send right now is that SpaceX will not skip a beat in execution going forward. We have flight four of Falcon 1 almost ready for flight and flight five right behind that. I have also given the go ahead to begin fabrication of flight six. Falcon 9 development will also continue unabated, taking into account the lessons learned with Falcon 1. We have made great progress this past week with the successful nine engine firing. As a precautionary measure to guard against the possibility of flight 3 not reaching orbit, SpaceX recently accepted a significant investment. Combined with our existing cash reserves, that ensures we will have more than sufficient funding on hand to continue launching Falcon 1 and develop Falcon 9 and Dragon. There should be absolutely zero question that SpaceX will prevail in reaching orbit and demonstrating reliable space transport. For my part, I will never give up and I mean never. Thanks for your hard work and now on to flight four. --Elon--

SpaceX Falcon 1 Launch Failure
by Armando Mercado 03 Aug '08

There has been an apparent launch failure of Falcon 1. Lift off was at 0333UTC. The "rocket cam" on the booster showed the climb out then the video stream on the web site went black. At 0338UTC launch control reported an "anomaly" and details would be posted when they became available. This would be SpaceX 3rd attempt to put a payload in orbit.

Fw: SpaceX Sets August 2 for Falcon 1 launch
by Andrew Glasbrenner 02 Aug '08

02 Aug '08

Untitled DocumentFYI, this launch has two satellites with amateur band beacons, although it will be a very low inclination orbit. Anyone in Florida or South Texas might have a shot at hearing them. 73, Drew KO4MA/KL7 ----- Original Message ----- From: SpaceX News To: ko4ma(a)amsat.org Sent: Saturday, August 02, 2008 4:10 PM Subject: SpaceX Sets August 2 for Falcon 1 launch FOR IMMEDIATE RELEASE Contact: Diane Murphy | VP, Marketing and Communications media(a)SpaceX.com 310.363.6714 SpaceX Sets August 2 for Falcon 1 launch First Privately Developed Liquid Fuel Rocket to Orbit -------------------------------------------------------------------------- Hawthorne CA - Space Exploration Technologies Corp. (SpaceX) has scheduled the launch of the Falcon 1 Flight 3 mission for Saturday, August 2nd. The launch window will open at 4:00 p.m. (PDT) / 7:00 p.m. (EDT) / 23:00 (UTC) and remain open for five hours. Webcast will begin approximately 30 minutes before launch. If launch is delayed for any reason, SpaceX has range availability to resume countdown through August 5. Lift-off of the vehicle will occur from SpaceX's Falcon 1 launch site at the Kwajalein Atoll, about 2500 miles southwest of Hawaii. Falcon 1 launch facilities are situated on Omelek Island, part of the Reagan Test Site (RTS) at United States Army Kwajalein Atoll (USAKA) in the Central Pacific. Designed from the ground up by SpaceX at headquarters in Hawthorne, Calif., Falcon 1 is a two-stage, liquid oxygen and rocket-grade kerosene powered launch vehicle. The first stage is powered by a single SpaceX Merlin 1C Regenerative engine - flying for the first time on this Flight 3 mission. A "hold before liftoff" system enhances reliability by permitting all systems to be verified as functioning nominally before launch is initiated. The Falcon 1 second stage is powered by a single SpaceX Kestrel engine. Falcon 1 is the first new orbital rocket in more than a decade. Merlin is the first new American hydrocarbon engine for an orbital booster to be flown in more than 40 years and only the second new American engine of any kind in more than a quarter century. After achieving orbit, Falcon 1 will be the first privately developed, liquid fuel rocket to orbit the Earth. The primary customers for the Falcon 1 launch are the Department of Defense, Government of Malaysia and NASA. Falcon 1 is carrying a payload stack of three separating satellites that will orbit at an inclination of 9 degrees: a.. The Trailblazer satellite was developed by SpaceDev of Poway, Calif., for the Jumpstart Program of DoD's Operationally Responsive Space (ORS) Office, as a test platform to validate the hardware, software and processes of an accelerated microsatellite launch. Trailblazer is deployed from the Falcon 1 second stage shortly after the shut-down of the second stage engine, about 10 minutes into flight. a.. Deploying four to eight minutes later will be two NASA small satellites: PRESat, a micro laboratory from NASA's Ames Research Center, and then NanoSail-D, which will unfurl an ultra-thin solar sail, developed by NASA's Marshall Space Flight Center, in collaboration with NASA Ames Research Center. a.. The three separating satellites attach to the Falcon 1 second stage via the Secondary Payload Adaptor and Separation System, (SPASS), developed by ATSB, a company owned by the Government of Malaysia that develops and commercializes space technology. The SPASS was engineered by Space Access Technologies of Ashburn, Va. SpaceX will provide live coverage of the Falcon 1 Flight 3 mission via webcast at: www.SpaceX.com . The webcast will begin 30 minutes prior to launch and will include mission briefings, live feeds and launch coverage from the launch site at the Kawjalein Atoll, as well as a special video tour of SpaceX facilities by Elon Musk, CEO and CTO. Post-launch, high resolution B-roll video footage and photos will be available for download by contacting: media(a)spacex.com . About SpaceX SpaceX is developing a family of launch vehicles intended to increase the reliability and reduce the cost of both manned and unmanned space transportation, ultimately by a factor of ten. With its Falcon line of launch vehicles, powered by internally-developed Merlin engines, SpaceX offers light, medium and heavy lift capabilities to deliver spacecraft into any altitude and inclination, from low-Earth to geosynchronous orbit to planetary missions. SpaceX currently has 12 missions on its manifest, excluding the two previous Falcon 1 demonstration flights, plus indefinite delivery/indefinite quantity (IDIQ) contracts with NASA and the US Air Force. As a winner of the NASA Commercial Orbital Transportation Services competition (COTS), SpaceX is in a position to help fill the gap in American spaceflight to the International Space Station (ISS) when the Space Shuttle retires in 2010. Under the existing Agreement, SpaceX will conduct three flights of its Falcon 9 launch vehicle and Dragon spacecraft for NASA, culminating in Dragon berthing with the ISS. NASA also has an option to demonstrate crew services to the ISS using the Falcon 9 / Dragon system. SpaceX is the only COTS contender that has the capability to return pressurized cargo and crew to Earth. The first Falcon 9 will arrive at the SpaceX launch site (complex 40) at Cape Canaveral by the end of 2008 in preparation for its maiden flight. Founded in 2002, the SpaceX team now numbers over 500, located primarily in Hawthorne, California, with four additional locations: SpaceX's Texas Test Facility in McGregor near Waco; offices in Washington DC; and launch facilities at Cape Canaveral, Florida, and the Marshall Islands in the Central Pacific. # # # Falcon 1 launches from the SpaceX launch site in the Central Pacific. The Falcon 1 is the first rocket fully designed and developed in the 21 st Century that will provide both reliable and cost efficient transport of satellites to low Earth orbit. SpaceX's Falcon 1 will be the first privately-developed, liquid fuel rocket to orbit the Earth. ### You are subscribed as ko4ma(a)amsat.org. To unsubscribe please click here.

Hi all. - Thought this was interesting....... McGregor TX – Space Exploration Technologies Corp. (_SpaceX_ (http://www.spacex.com/index.php) ) conducted the first nine engine firing of its _Falcon 9_ (http://www.spacex.com/falcon9.php) launch vehicle at its Texas Test Facility outside McGregor on July 31st. A second firing on August 1st completed a major NASA Commercial Orbital Transportation Services (COTS) milestone almost two months early. At full power, the nine engines consumed 3,200 lbs of fuel and liquid oxygen per second, and generated 832,000 pounds of force (lbf) – four times the maximum thrust of a 747 aircraft. SpaceX is developing a family of launch vehicles intended to increase the reliability and reduce the cost of both manned and unmanned space transportation, ultimately by a factor of ten.

There's a pass later, around 03:50-ish UTC, that gets to 50 degrees maximum elevation here. It should be good for most of the eastern U.S. I'm going to try it again. 73, Tim - N3TL Athens, Ga.

Working DO-64 portable?
by Ivo Klinkert, PA1IVO 01 Aug '08

01 Aug '08

Hello all, Tonight on the 2031 UTC pass over The Netherlands, DO-64 was passing over at an 86 degrees maximum elevation. So I tried with a portable setup (2x FT817 and an Arrow antenna) as PA1IVO/P. For a short period of time, I was able to hear myself quite clearly on the downlink, and another station called QRZ to me (probably because of my manual doppler correction on the uplink only, he was not able to copy my call sign). So, with the right conditions it must be possible to work DO-64 QRP/portable (which did not succeed a few days ago on the AMSAT-UK Colloquium unfortunately). So I will try again tomorrow on the 950 UTC pass, see if we can have some fun again with DO-64. And of course, thanks to the Delfi-C3-team for this new amateur radio satellite. 73, Ivo.

Good question! I was going to send you the standard response saying she is napping in the dark, but just did a quick check myself and PCSAT (W3ADO-1) has not been heard since 2 July at 11:52:39 and the last station to digipeat through it was SP9UX on the 5th at 04:09:14 and the last USA station was W4AEJ on the 1st at 14:04:28... But I also notice that PCSAT passes are at night over the Northern Hemisphere where everyone lives. Maybe we can wake up someone down-under to see if they can listen for PCSAT (W3ADO-1) NO-44 on 145.825 MHz...

Agreed! I have the same problem working passes from the Sierra Nevada and i don't expect most Alaskans to make low elevation passes (thus choose my passes accordingly). Here are some predictions for today. I'm only setup for mode J-FM at the moment, but others may found linear transponder passes useful, and AO-27 is not included. (Even with the updated schedule, AO-27 seems to go to telemetry before it even rises as far north as BP54.) 73's and best of luck! -- KD6PAG (Networking Old-Timer, Satellite QRPer) ------------------------------------------------------------------------------- Common passes of AO-7, SO-50, AO-51 and VO-52 for Anchorage and Santa Rosa, CA Fri 01Aug08 15:02:33 15:09:55 15:17:21 00:14:49 293 18 109 74.4* Anchorage Fri 01Aug08 15:10:56 15:17:47 15:24:34 00:13:38 338 48 118 26.1 Santa Rosa SO-50 15:10:56 15:17:21 6.4 min overlap (Fri 15:02 UTC/08:10 PDT) Fri 01Aug08 16:43:25 16:50:39 16:57:54 00:14:29 302 224 145 50.0* Anchorage Fri 01Aug08 16:51:36 16:58:39 17:05:38 00:14:02 321 246 169 40.4* Santa Rosa SO-50 16:51:36 16:57:54 6.3 min overlap (Fri 16:43 UTC/09:51 PDT) Fri 01Aug08 16:46:34 16:53:34 17:00:58 00:14:24 19 93 169 34.3 Anchorage Fri 01Aug08 16:52:04 16:58:16 17:04:44 00:12:40 353 295 237 17.3 Santa Rosa AO-51 16:52:04 17:00:58 8.9 min overlap (Fri 16:46 UTC/09:52 PDT) Fri 01Aug08 17:20:26 17:31:18 17:42:06 00:21:40 19 97 174 42.6* Anchorage Fri 01Aug08 17:25:54 17:36:05 17:46:26 00:20:31 8 300 230 34.5 Santa Rosa AO-7 17:25:54 17:42:06 16.2 min overlap (Fri 17:20 UTC/10:25 PDT) Fri 01Aug08 19:29:28 19:35:41 19:41:58 00:12:30 21 92 161 25.6 Anchorage Fri 01Aug08 19:34:49 19:40:27 19:46:09 00:11:20 353 293 234 17.0 Santa Rosa VO-52 19:34:49 19:41:58 7.2 min overlap (Fri 19:29 UTC/12:34 PDT) Sat 02Aug08 00:48:21 00:58:14 01:08:11 00:19:50 85 20 316 28.9 Anchorage Sat 02Aug08 00:41:30 00:49:37 00:57:44 00:16:14 96 48 359 13.1 Santa Rosa AO-7 00:48:21 00:57:44 9.4 min overlap (Sat 00:48 UTC/17:41 PDT) Sat 02Aug08 02:32:35 02:39:07 02:45:55 00:13:20 121 52 343 29.2 Anchorage Sat 02Aug08 02:24:45 02:31:37 02:38:37 00:13:52 156 74 352 58.9* Santa Rosa AO-51 02:32:35 02:38:37 6.0 min overlap (Sat 02:32 UTC/19:24 PDT) Sat 02Aug08 02:38:47 02:49:35 03:00:23 00:21:36 122 46 330 51.3* Anchorage Sat 02Aug08 02:29:56 02:40:49 02:51:46 00:21:50 148 67 347 62.2* Santa Rosa AO-7 02:38:47 02:51:46 13.0 min overlap (Sat 02:38 UTC/19:29 PDT) Sat 02Aug08 04:10:40 04:17:40 04:24:56 00:14:16 166 256 343 75.5* Anchorage Sat 02Aug08 04:05:19 04:10:50 04:16:34 00:11:16 215 269 324 12.6 Santa Rosa AO-51 04:10:40 04:16:34 5.9 min overlap (Sat 04:10 UTC/21:05 PDT) Sat 02Aug08 04:31:03 04:42:14 04:53:25 00:22:22 164 250 338 71.0* Anchorage Sat 02Aug08 04:23:49 04:34:00 04:44:11 00:20:22 197 265 332 27.6 Santa Rosa AO-7 04:31:03 04:44:11 13.1 min overlap (Sat 04:31 UTC/21:23 PDT) ===============================================================================

WISP tracking problem.
by Nuril -9W2NRL 01 Aug '08

01 Aug '08

Dear all, I got problem with my tracking s/w. I used KCT driver with WISP tracking software to control my G-5500. Everything is calibrated but when it come to park my antenna, it will park at az=180 deg instead of 0 deg. It start to track the satellite based on initial park value (180+actual azimuth). I have no problem with my elevation. Any help would be most welcome. Thanks 73 9w2nrl

Vanishing PCSAT?
by Robert Bruninga 31 Jul '08

31 Jul '08

> I've probably missed the "answer" on AMSAT > but where is PCSAT? Good question! I was going to send you the standard response saying she is napping in the dark, but just did a quick check myself and PCSAT (W3ADO-1) has not been heard since 2 July at 11:52:39 and the last station to digipeat through it was SP9UX on the 5th at 04:09:14 and the last USA station was W4AEJ on the 1st at 14:04:28... But I also notice that PCSAT passes are at night over the Northern Hemisphere where everyone lives. Maybe we can wake up someone down-under to see if they can listen for PCSAT (W3ADO-1) NO-44 on 145.825 MHz... May not decode it, but should be able to hear it attempting to send a packet once a minute.. Only in the sun, of course... So Robert, thanks for bringinig this to our attention... PCSAT was launched on 30 Sept 2001. Bob, Wb4APR

Thanks for the AO-7 qso

Thanks Doug, for sticking with my puny signal through two passes to make the QSO on AO-7 tonight. I was using a FT-817, Arrow antenna, and SATPC32, while portable on the bank of the Resurrection River just down from Exit Glacier in BP50, Seward, AK. I've been on a few AO-51, AO-27, and SO-50 passes from up here and made a handful of QSOs despite the mountains and trees, but this AO-7 QSO was tops. 73, Drew KO4MA

Antenna design
by Rosemary & Starr 31 Jul '08

31 Jul '08

Hi All, I am thinking of doing some changes to my 2m antenna set up. One thing I would like to do is improve the front to back ratio. If my memory serves me correctly a second reflector placed behind the first reflector will archive this, however if so, this would increase the boom length. Is there some other method that could be used to improve the front to back ratio? Thanks. 73 Starr ZL3CU

Help requested for Kenwood Ts-790E
by Vincenzo Mone 31 Jul '08

31 Jul '08

Hi to the list, I own an Kenwood TS-790E Transceiver. Today I wanted to try the DO-64. I've set the radio on CW and sent it on air. I've noticed that the S-Meter stopped on 4 of the dB line. Without touching anything and just passing from CW to FM I saw the S-Meter needle going up till over the 9 of the dB line. Before I made these test I have set the radio with 10 watts in FM. I have measured the SWR and have noticed that there are none high SWR but Just 1.3 on both modes but I saw the power drop down to 5 watts in CW While it was 10 Watts on FM. Please anybody can tell me what has happened? Thanks. 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Delfi-C3 Status update 29 July 12:30 UTC
by Wouter Jan Ubbels 31 Jul '08

31 Jul '08

Hi all, please find below the latest status update of the Delfi-C3 / DO-64 satellite 1. We have concluded the first three months of science mission with great success. A big word of thanks to all amateur radio operators around the world for collecting and forwarding telemetry, sending reception reports and observations, and thanks for all the tremendous support we have received. As of today, we have collected 396564 AX.25 frames through the worldwide network... a truly amazing number. Thank you all so much. 2. Delfi-C3 has been switched to permanent transpondermode during the 10:00 UTC pass today (July 29th) over the Delfi-C3 groundstation in The Netherlands. This means that the spacecraft now boots in transpondermode as soon as the spacecraft exits eclipse. This was verified by a successful OBC database dump shortly after that. 3. We plan to switch the satellite back into either basic or science mode, approx. once every 2 weeks for short times during passes over our groundstation for housekeeping purposes. During these passes either the 145.870MHz or 145.930MHz downlink will be on transmitting 1200Bd BPSK, and the transponder will then be off. We would like to encourage everyone to forward telemetry using RASCAL in the usual way during these passes. Longer periods of BPSK telemetry will be announced on the BB. 4. Reports have indicated a slight frequency offset of the transponder, i.e. an uplink of 435.556MHz corresponds to 145.900MHz in the downlink passband. This was actually known before launch, and is caused by a slight frequency offset in one of the spacecraft's local oscillators. The video on YouTube is a video from the first transponder contact using our "flatsat" transponder prototype in early 2007, which is not the same as the flight model. However, the flatsat prototype also showed a slight frequency offset, as G0MRF pointed out. 5. The transponder mode beacon is at 145.870MHz, approx 10dB below PEP, transmitting a CW beacon message, followed by a commemorative Sputnik message consisting of 6 dits. Actually, the CW beacon is transmitted using Double Sideband, there are two CW carriers 1200Hz apart. (Guess where that number comes from hi:) 6. Reports on the transponder's operation are more than welcome, either on the BB (which is read by us on a daily basis) or directly to info at delfic3.nl Having said all this, the team is happy to open the transponder for use, and wishes you good DX. Enjoy! 73 on behalf of the Delfi-C3 team, Wouter Jan Ubbels PE4WJ

Re: Upcoming Scotland/Shetlands trip
by Richard Crow 30 Jul '08

30 Jul '08

John, Sure, I'll "shoot the Atlantic" with you. I'm assuming you'll bring equipment to work the FM LEO(s). If so, I've worked several stations in various parts of England and one in Madrid, Spain on AO-51. AO-51 would be my FM LEO of choice for this. I live near Binghamton, NY where I have a hillside location about 500 yards up behind my house with an excellent view. From this spot I can work AO-51, and other FM LEO(s), down to 1 degree above the northeastern horizon. In fact, anyone who can get to the seashore in the eastern U.S., from New Jersey to Maine, should be able to do this. Canada's Atlantic provinces and Newfoundland are even better. All you need is a clear shot across the Atlantic Ocean to the northeast to access AO-51 while its also in view of the extreme western edge of Europe. To connect Europe to North America on AO-51 will, of course, require an AO-51 pass down the center of the Atlantic. This means you'll be working a pass with a maximum elevation of 1 or 2 degrees, as will I. My experience has been that such a pass will give us a 30 to 60 second time window during which we can exchange call signs. So when the time comes, you'll need to call me often for several minutes to hit the time window just right. I'll do the same. Perhaps if pass conditions are perfect, we may get a couple of minutes. In addition, in light of the comments above, I recommend you try this from the west coast of Scotland with a solid view across the Atlantic to the southwest. Be advised, the west coast of Scotland can be extremely windy, so come prepared. Also, I know you be operate QRP. But bring as much transmit power as you can. With a pass down the center of the Atlantic, AO-51 will be approximately 2000 miles away from both of us. My experience is that 5 watts to AO-51 at this distance is "iffy". I'll be running 50 watts, so I'm pretty sure you'll hear me as others have before. Since I'll have to drag my portable station into position, we'll have to pick out an AO-51 pass and set up a schedule, or two (back-up), off-line. Good Luck! -Richard, N2SPI

Takes timing, planning and luck!. > 73 Bob W7LRD You're right, Seattle should not be hard on AO-7. There's even some theoretical overlap of 0.8 minutes from the Shetlands to Redding, California (thus 49 states), but you'd better have good horizons and a good receiving setup. I'll be seeing if that much overlap might be enough to make it to Alaska on AO-51 (as Iceland has been worked from there without sked). What it really came down to was size/weight and how to compensate for doppler on the uplink, as the SSB rig that i've been offered doesn't have computer control. Even if it did, there are too many software issues to solve prior to travel and i'd need to take the docking station (nearly doubling the computer's weight) if i needed a real serial port. But what it really comes down to is that don't want to carry any more weight (that is assuming the rig[s] would even fit in my luggage), as it does not make sense to have a car for the third of the trip that we're in Edinburgh or Glasgow. So unless someone in the SF Bay Area (or Scotland) can offer a better idea, higher orbit LEO's won't happen this trip. > "if this were easy, everyone would be doing it" Yeah, maybe next trip i'll have access to suitable equipment. I've been talking to another local ham about a small dsPIC-based SSB transmitter and/or receiver. But even if hardware existed a month ago, it's unlikely the software issues would have been solved in time... It's too bad that Yubileiny doesn't have mode J-FM. Maybe someday someone else can put up something more useful into that kind of an orbit. -- KD6PAG

by Robert Felt 30 Jul '08

30 Jul '08

Wednesday 7-30-08 To All: For Sale - "TrakBox" Satellite tracker, antenna rotor controller for stand alone operation. (JARL design, TAPR kit) The trakbox is a self-contained, stand-alone rotor/radio control for use with your satellite stations. Select the satellite you wish to track from a front panel control and the TrakBox will steer your antennas in both azimuth and elevation to track the selected satellite when it is or above your horizon. In addition, if you have a radio with a computer interface, the TrakBox will tune your transmitter and receiver and correct them for doppler shift. TrakBox is set up to directly interface to Kenpro, Emmoto, and Yaesu dual-axis rotators which include a computer interface. Trakbox includes a serial port to allow you to set the real-time clock (which is battery backed), your station location (latitude, longitude and elevation) and the keplerian elements for the satellites you are interested in (up to 40 satellites may be loaded, and the elements may be uploaded in ASCII in either the AMSAT or NASA formats). A two-line LCD display is updated every second, showing the azimuth and elevation of a satellite, along with the satellite ID and GMT. See Complete description and docs at TAPR web page: http://www.tapr.org/kits_trakbox.html I built this kit from TAPR back in the late 1990's. It provided excellent service. Still works fine.

DO-64 and Wisp
by Vincenzo Mone 30 Jul '08

30 Jul '08

Hi to the list, I am using wisp and would like to add the DO-64. I have added it as keplerians but I cannot get it work with the Rascal program when the bird comes in AOS. I have substitute in the scheduling Tab, the line: C:\Wisp\MSPE.EXE %S With the line: C:\Rascl\RASCAL.JAR But when the DO-64 comes in AOS the program do not run and I get the following GSC error: Error running program.GSC was unable to find the program associated with this Satellite, or there was an error while running it. I've tried also with this line in the command above: C:\Rascl\RASCAL.JAR %S But get the same results. Any suggestion how to solve it' Thanks in advanced. 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Upcoming Scotland/Shetlands trip
by John Mock KD6PAG 30 Jul '08

30 Jul '08

I'll be in Scotland from 13 August through 2 September, with 16 August through 21 August 08 (1200Z) in the Shetland Islands. I'll primarily be trying to work the eastern Canada and northeastern parts of the US, and we'll see about Continental passes (as i've had rather disappoiting results trying to operate from France on two previous occasions). I will be using an antenna similar in characteristics to an 'Arrow' and run QRP. If i've figured this correctly, likely grid squares include IO66, IO75, IO76, IO77, IO85, IO86 and IP90; and possible grids are IO67, IO78, IO87, IO88 and IO99. I'll use what is customary in each region, that is, a four-way exchange with six character grid squares working Europe and the quicker exchange with four character grids expected in North America (in order to maximize satellite usage). I may post specifics to the AMSAT-BB if Internet access is convenient while i'm over there. Note that i won't be quite as active as on my two recent road trips as i won't be traveling solo (and have no idea what my western horizons will look like). As usual, with North America, i will send out QSL cards after i return home and get a chance to transcribe all of the passes; you don't need to send me a card or SASE. Just patience is all that i ask if i already have your grid square. However, if i have not worked you before, i'd greatly appreciate it if you would set up a sked to work me at home (primarily CM88, also CM87; your choice) so i can send you (at least) two cards. Cards from Europe would be appreciated and you will likely get my card even if you don't send yours. I hope to talk to you. 73's and best of luck! -- KD6PAG (Networking Old-Timer, Satellite QRPer)

Re: Delfi-C3 pass 0846 UTC over Denmark
by Wouter Jan Ubbels 30 Jul '08

30 Jul '08

Hi Ib, thank you very much for your observations, I presume that the frequency offset of 9kHz you state takes Doppler into account? W.r.t. signal strength, it certainly helps a lot to switch polarization, both the uplink and downlink antennas on the spacecraft are turnstile antennas, which have circular polarization, which is max. circular when the long axis of the satellite is in your direction. Since the circularity / axial ratio of the downlink antennas is very good (the uplink is somewhat worse), listening on the opposite circular polarization (provided that you use circular antennas on your side of course) may wipe out the signal completely:) 73 & hope to work you soon via DO-64 Wouter PE4WJ

Delfi-C3 pass 0846 UTC over Denmark
by OZ1MY 30 Jul '08

30 Jul '08

Hi all, The transponder frequency seems to stabilize at + 9 kHz for the uplink like Stefan VE4NSA observed in his e-mail. As I have written before it can be up to + 15 kHz when it is just turned on - and then it goes down 2 - 3 kHz during the pass. During this pass the frequency stayed at the + 9 kHz - no drift. Only problem was a very small signal from the satellite. Thanks for a new satellite to all at Delfts. By the way heard G7HIA testing but very weak. 73 OZ1MY Ib

WD9EWK's 17-22 July 2008 road trip report (long)
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Jul '08

30 Jul '08

Hi! This was a fun trip. Including a couple of days at the hamfest in Williams, Arizona, I spent 6 days on the road and traveled a total of 1603.5 miles/2580km. I operated from 10 different grids in and around Arizona, and logged 169 contacts. At the hamfest and throughout this trip, I used the same station from the back of my Hyundai Santa Fe - an Icom IC-2720H 2m/70cm FM mobile radio at either 5W or 15W output, into an Arrow Antennas handheld 2m/70cm Yagi. I used either KD2BD's PREDICT program or the AMSAT web site to know when the passes would occur, coupled with the AO-27 Satellite Scheduler program to know when the AO-27 repeater would be on during those passes. Thursday (17 July) afternoon and evening, from grids DM35xg and DM45ag east of Williams AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+15.570+n+112+0.00+w&jsv… Since I was heading to the hamfest in Williams a day early, and would be doing demonstrations from there (grid DM35vg), I decided to spend some time east of Williams on the DM35/DM45 boundary. I operated from the same spot I used in mid-April, along old route 66 north of the I-40 freeway about 10 miles/16km east of Williams. Lots of trees and shade, and a great place to play radio. I arrived in the area in time for a very high SO-50 pass at 1940 UTC, and worked just 2 stations. After driving to a nearby truck stop to get lunch, I returned for two AO-27 passes at 2051 and 2232 UTC. I made 11 contacts between those two passes. I then drove to Williams, to see where my AMSAT table would be at the hamfest, check into a motel, and then returned to this spot for an evening AO-51 pass (0220 UTC, 18 July). I only made 8 contacts on the evening pass, not bad for the first of several days on the road. Friday (18 July) and Saturday (19 July), from grid DM35vg at the Williams AZ hamfest: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+15.511+n+112+11.105+w&i… AMSAT had a table in the vendor hall at the hamfest, which saw a lot of traffic. Along with that, I did demonstrations from outside the hall. I had good crowds for each of the 4 demonstrations I did. I did demonstrations on AO-51 and AO-27 on Friday, and AO-51 and SO-50 on Saturday. I had hoped to do an AO-27 demonstration on Saturday afternoon, but a thunderstorm cancelled that plan. For the 4 passes, I made a total of 22 contacts. Not bad for those demonstrations. I answered lots of questions from hams passing by the table, so I considered this a successful hamfest. A regular on the FM satellites, "Uncle" Larry WA6DIR, stopped by while traveling east - nice to see him around the hamfest. Sunday (20 July) morning, from grid DM46vr in Kayenta AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+42.520+n+110+14.895+w&i… Since the hamfest was only scheduled for Friday and Saturday, I had thought about taking a road trip for a few days after the hamfest. Some sightseeing, and - of course - some operating from wherever I happened to go. I drove over 500 miles/800km this day, and was able to operate from 4 different grids in northern Arizona and southern Utah. I left Williams early, and about 2.5 hours and over 160 miles/257km later I stopped for lunch at Kayenta - a small town on the Navajo Nation reservation in northeastern Arizona. At this point, I was less than 50 miles/80km from the location I hoped to operate from in the afternoon (the DM56ex/DM57ea boundary near the Arizona/Utah state line), and about 40 minutes from an SO-50 pass. A gasoline station at the junction of US routes 160 and 163, the southern approach to Monument Valley, was a good place to work my first pass of this day. After 8 contacts in 10 minutes during the pass, I packed my gear and moved east to the next location I would operate from - as I finished my lunch on the road. Sunday (20 July) afternoon, from grids DM56ex and DM57ea in southern Utah: http://maps.google.com/maps?f=q&hl=en&geocode=&q=37+0.00+n+109+36.567+w&ie=… After less than an hour, I reached the next spot I would operate from - the line between grids DM56ex and DM57ea in southern Utah along US route 191, just north of the Arizona/Utah border. The Arizona/Utah state line at this point is just south of the grid boundary, in San Juan County and still on the Navajo Nation. This would be the only stop on my trip where I would operate from Utah. This is a very remote spot, a location that several regular satellite operators told me they needed for their logbooks. Once I confirmed the location with my GPS receiver and took some pictures, I set up for the SO-50 pass at 1925 UTC. This pass only covered the west coast of North America, and I made just 4 contacts. After this pass, I drove around this area to look around before the upcoming AO-27 passes. When AO-27 turned on at 2106 UTC for the first pass of the afternoon at this location, to the east of my location, it was busy as usual. Once stations heard my location, I started working them quickly. Seventeen stations logged in 7 minutes! This might have been a personal record, and I thank all of the stations on that pass for cooperating with my attempt to hand out contacts from this location as quickly as possible. I had hoped to work the next (western) AO-27 pass from here, before driving to my next stop for the night. A thunderstorm with lots of rain and lightning near me changed that plan. I packed my gear, and moved on. Sunday (20 July) evening and Monday (21 July) morning, from grids DM46fx and DM47fa near Page AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=37+0.00+n+111+34.270+w&ie=… Over 150 miles/250km of driving from DM56ex/DM57ea brought me to Lake Powell, on the Arizona/Utah border. Once again, the Arizona/Utah state line was not the grid boundary. This time, the grid boundary was on the Arizona side of the state line. I found the spot I wanted to work from, near US route 89 south of the state line and Lake Powell, and waited for the AO-51 pass this evening (0200 UTC Monday). This pass was virtually overhead, so I planned to work only this pass this evening. These two grids are another pair of rare grids on the satellites, and the overhead pass meant lots of stations to hear and work. I worked a total of 19 stations from central Mexico to Alaska and Canada's Northwest Territories (the first time I've ever worked a VE8 station, on any band or mode!). After the pass, it was time to find a motel for the night and rest up before another day's drive. I had driven over 500 miles/800km today. I was able to work another AO-51 pass on Monday morning just before 1600 UTC, logging 4 more contacts. With 23 contacts from these two grids during 2 passes, I thought that was a good effort. Monday (21 July), midday, from grid DM36pu west of Fredonia AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+52.318+n+112+40.515+w&i… On my way west toward Las Vegas, I stopped along Arizona route 389 west of the small town of Fredonia for an SO-50 pass. I wanted to put grid DM36 on the air as much as possible, before reaching Las Vegas later in the day, and this was a convenient stopping point. I did not want to go further west, as I would get closer to a wall of mountains to the north. Since there was a gasoline station near this spot, I went there to get some snacks and something to drink before the pass. This area is called the "Arizona Strip", between the North Rim of the Grand Canyon and the Utah state line, where very few people live. When SO-50 was audible around 1814 UTC, I was surprised to hear several stations on a pass during the middle of a weekday. I logged 7 contacts from this spot, before moving to another location on the west edge of DM36. Monday (21 July) afternoon, from grid DM36at near Scenic AZ and Mesquite NV: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+49.994+n+113+59.929+w&i… I was driving hard to get to this area before the two AO-27 passes this afternoon, and saw a tall line of mountains to the east. I did not have time to get to the DM26/DM36 grid boundary in this area for the first AO-27 pass, a shallow eastern pass. I was hoping to get on from DM36 for these passes, as I knew I could be on from DM26 later in the day at Las Vegas. When I parked at this spot, next to the I-15 freeway a few miles/km east of the Arizona/Nevada state line in Mohave County, I was ready at the scheduled start of the AO-27 pass. Due to those mountains, I lost the first 30 seconds or so of the pass, before the satellite was clear of those mountains. Even with that, I was able to work 11 stations across the continental USA and Mexico. After the pass, I went to get lunch and then return to this area - to find a better spot on the DM26/DM36 boundary before the next AO-27 pass. Monday (21 July) afternoon, from grids DM26xt and DM36at in Scenic AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+48.020+n+114+0.00+w&ie=… Before the later AO-27 pass to the west, I found this spot on the DM26/DM36 grid boundary east of the Arizona/Nevada state line. I could find a spot and not worry about the mountains to the east, and still put DM36 on the air one more time before heading down the I-15 freeway to Las Vegas. I set up my station, and proceeded to work 9 stations from central Mexico to western Canada during this 7-minute pass. A total of 27 contacts from 3 different locations in DM36 today. Not bad. On to Las Vegas... Monday (21 July) evening and Tuesday (22 July) morning, from DM25jx and DM26ja in Las Vegas NV: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+0.00+n+115+10.230+w&ie=… Before this trip, I looked at maps and saw the DM25/DM26 grid boundary passed through the south side of the Las Vegas metropolitan area. This would be a good way to put the unusual DM25 grid on the air along with the more-common DM26 grid. Along this part of the Las Vegas Strip (Las Vegas Blvd.), there were lots of empty spaces. Perfect places to set up for satellite passes. I drove less today, covering over 345 miles/556km from Lake Powell to Las Vegas - still a lot of driving in one day with the stops. Once I found this spot, I set up for the first of 2 AO-51 passes this evening (0122 UTC Tuesday). I was ready, and the activity was steady throughout the pass. I logged contacts with 22 different stations from central Mexico to western Canada on this pass! Again, thanks to all who were on that pass for making this a very successful effort - and more contacts on one pass than I've ever worked before. Later in the evening, I worked the western AO-51 pass from the same spot starting at 0302 UTC. After hearing a couple of stations who did not respond to my calls, I worked 8 other stations. I was able to work an SO-50 pass Tuesday morning just after 1700 UTC before leaving Las Vegas, logging just 2 contacts. A total of 32 contacts during 3 passes from DM25/DM26 - a very good show! Tuesday (22 July) afternoon, from DM24qx and DM25qa in Camp Mohave AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+0.00+n+114+35.610+w&ie=… This was my last day on the road, and I wanted to try for grid DM24 at least once. Time permitting, and depending how I felt, I hoped to also try for possibly grid DM23. There was an overhead AO-27 pass this afternoon, and I decided to drive south from Las Vegas to this area along the Arizona (east) side of the Colorado River, south of the cities of Laughlin NV and Bullhead City AZ in Mohave County. Despite the mountains on both sides of the Colorado River, I had a good view of the sky in all directions. The AO-27 pass I intended to work was another virtually overhead pass. I parked my truck to shade me as much as possible from the 107F/42C heat, and prepared for the pass. When the AO-27 repeater switched on at 2149 UTC, I went to work. Again working stations from central Mexico to western Canada, I logged 15 contacts in the first 5 minutes of the 7-minute pass. I may sound like a broken record by now, but I have to thank the other stations on that pass for allowing so many quick contacts to happen in the limited time on AO-27. After this pass, I decided to end my radio operating and just drive home. I still had about 4 hours to go before returning to Phoenix, and with the sun still getting warmer as the afternoon went on... I decided to disassemble my Yagi and pack everything up for the drive home (247.5 miles/398km from Camp Mohave to Phoenix). ********** During my trip, there were stations who worked me from many of the grids I stopped in. Here's a summary of the callsigns I worked from the most grids while I was on the road... All 10 grids: K7RST, W6ASL, W6ZQ, XE1AO 9 grids: N3TL, WA4NVM 8 grids: N5AFV, XE2RV 7 grids: KD8CAO 6 grids: VE7JRX, W5VG, XE1BMG, XE2BHL 5 grids: KE7SAK, VA7VW, WA4SCA, WA8SME, XE2YW Even though the price of fuel was high - prices from $3.959/gallon ($1.046/liter) in western Arizona up to $5.19/gallon ($1.374/liter) in Needles CA near the borders of Nevada and Arizona - I was able to cover this distance and not single-handedly prop up some of the oil- producing countries. I had a $50 Shell gift card I won at my office, that was used during this trip - plus good performance from my vehicle on the open road. When I returned home, I had already received some QSL requests. I will get some cards printed for each stop on my trip, and I should have them soon. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

AO51/GO32 Mobile Manual Tracking Table updated
by Robert Bruninga 29 Jul '08

29 Jul '08

The AO51 mobile tracking table only has 5 entries because the pass times repeat every 5 days so it can be reduced to a single table good for 2 months like this: EASTERN Daylight Time AO-51 01Aug 07Aug 13Aug 19Aug 25Aug ----- ----- ----- ----- ----- 0800 0855 0815 0740 0835 0935 0920 1910 2010 1930 1850 1950 2030 Cut/paste on your dashboard or shack bench. The table is good for a month or two and allows you to always estimate satellite passes within 5 minutes. You don't need no stinking PC for 2 months. These are the peak passes for your time zone. If one peak pass is shown, then there are two other lower passes 100 minutes earlier and later. If two modest passes are shown, then the others will probably be too low. TO use this on any day, just find the column nearest todays date and count forward or backward the number of days. SO for today (July 29th), start on 1 Aug and count (rotate) to the left 3 days. So tonight's pass will be at 1930 (and one at 1750 and 2110 ish) I updated the tables for both birds and each USA time zone on my Mobile Manual Tracking web page: http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html There are other hints there that allow you to be more accurate based on where you live in your time zone, etc. The table for the GO32 APRS satellite repeats every 9 days and is good for 3 months or so: EASTERN Daylight Time 01Aug 11Aug 21Aug 31Aug 10Sep 20Sep 30Sep 10Oct 20Oct ----- ----- ----- ----- ----- ----- ----- ----- ----- 0920 0855 0835 0810 0930 0905 0845 0820 0940 1015 0950 1025 1000 2035 2015 1955 1930 2005 2025 2005 1940 1920 2135 2110 2120 2100 If you get bored on your daily commute and want to see what the satellites are doing and you are on the road during these times, you don't need a PC. Just look at your dashboard, do a little mental processing, and bingo, you can estimate the next pass easily. Bob, WB4APR

Hi Alan / Ib That it is still operational over ZL after half an orbit is very encouraging. Perhaps we have seen the last of the 'feature' of turning off shortly after coming out of eclipse. As the team predicted. At Surrey the team announced the Delfi N3XT project (pronounced 'next'). The satellite will be a 3cube design but with bigger panels and 3 axis stabilization and a power budget much greater than DO-64. They are looking for ideas to put on the mission to give some amateur radio functionality in addition to the science they have planned. V down link and U uplink will be used for communications. I wonder if 'we' could suggest something in addition to the obvious transponder. - September deadline for the mission plan. Perhaps the BB could come up with a list of suggestions. Perhaps with 3 axis control, a small camera with an image to slowscan converter would be good. - Then the team can use it to confirm the pointing accuracy of the satellite and potentially use the GENSO network to issue a 'take picture' command.

Re: FO-29 telemetry
by SV1BSX 28 Jul '08

28 Jul '08

Hi Keith, N4ZQ I agree with you, however how can we prevent somebody to use the Satellite into Eclipse? Fortunately, the Satellite comes into Eclipse over populated areas -like Europe- before and after the midnight, so the traffic is minimal. That's good ! On the other hand, there are several areas where the Satellite has a terrible "jamming" on the Uplink, in the middle of the night. I have observed that, over M.East and W.Asia sometimes the Satellite is fully noisy, FMing too. Probably because the Satellite subzone between 145.8-146 MHZ is fully occupied by pirates, old VHF wireless phones etc. So, even without Ham-users, sometimes the satellite is fully overloaded. That is very bad in case where the Satellite is into Eclipse but, definitely we can not much to do in order to prevent that. As I remember, this Satellite has a function for electric management (UVC), in order to "Turn-ON" automatically the transponder, when came on Sunlight . Unfortunately, on UVC appeared a malfunction @ April'07. Normally, if the batteries are discharged and the satellite comes into Eclipse, the transmitter is turned OFF by the UVC. It is designed so that later an analog system transmitter becomes ON automatically when the terminal voltages of the battery exceed a set value after the power is available from the Solar Panels. However, it appears likely that a malfunction occurs for this function, and the terminal voltage cannot turn-ON the transmitter even if it exceeds the set value - unless commanded from the JARL's ground station. Therefore, without UVC-function and by carrying 12 years old Batteries, the Satellite is "naked". Even without traffic from Ham-operators during the Eclipse, it is not sure if that prolongs the FO-29's life. 73, Mak SV1BSX ----- Original Message ----- From: "Keith N4ZQ" <n4zq(a)netzero.net> To: <sv1bsx(a)yahoo.gr> Sent: Monday, July 28, 2008 3:25 PM Subject: Re: [amsat-bb] Re: FO-29 telemetry Very Interesting Data you collected, Mak.

Keith N4ZQ -- "SV1BSX" <sv1bsx(a)yahoo.gr> wrote: Hi Domenico, i8CVS last night I collected the Telemetry from FO-29. Date 27 July 2008, Orbit #58990. AOS 21:27, TCA 21:34, LOS 21:41. It is very interesting to point out that, the most part of TLM collected into Eclipe ! If I am not wrong, just the "Data1" is on Sunlight and the rest DATA on Eclipse. At 21:32 the FO-29 came on the dark, 2 minutes before the TCA. The confirming of Sunlight on "Data1" is obvious also by Solar-Panel Current (= 1000.0 mA). Also the battery has the biggest Voltage (16.4 ). In the next "Data 2,3,4, 5 & 6" where the FO-20 was on Eclipse, the Solar-Panel Current is just 9.8 mA. However, the battery voltage is droped down from 16.4 V (Data1 on Sunlight) to 14.2 V (Data 6 on Eclipse). That means 2.2 Volts lower in about 5 mins. I can't say if that is normal or not. It's just my notice and probably is OK that but, it should be very interesting if we can find an older TLM-Data into Eclipse in order to compare it with this one. Finally, the following data are 100% OK.

WISPDDE and IC-910H
by Sion Chow Q. C. (9W2QC) 28 Jul '08

28 Jul '08

Dear All, I migrating my satellite PC to a new maching, both of which uses Windows XP professional edition. All along, I have been using WISP and WISPDDE client for rotator and doppler tracking and plan to continue using the same software. Rotator control is working great here with the LVB tracker and Yaesu G-5500. However, doppler is not working as how it should be. For this, I use the CI-V cable from G4ZLP which was working perfectly OK on the old machine. I have configured WISPDDE client to IC-910H as radio 1. However, WISPDDE gives errors (when the pass starts, and frequency is passed from WISP to WISPDDE client via DDE) like "Unable to cancel duplex command" and some other errors whenever "Bidirectional interface" is enabled. If "Bidirectional interface" is unchecked, everything works fine. I cant this enabled (causes WISPDDE client to hang up), so for now I have to let it be disabled. I use the IC-910H in satellite mode with this setup, as this is required to get the downlink on the top (RX) and uplink on the bottom (TX). Would be glad if anyone could help me on this matter. Although this is not a serious trouble, I cant get WISPDDE to recognise small changes/compensation made using the VFO knob on the IC-910H especially when copying CW satellites. Also, in this configuration, IC-910H could not switch bands automatically. Say for example, IC-910H is set for TOP band, 70 CM RX, Bottom Band, 2M TX. This works well automatically for Mode J satellites like AO-51 and GO-32. But when ISS passes comes in, it will not reverse the top and bottom bands. (I have configured 2M on top (RX - 145.800 MHz), 70CM on the bottom (TX - 437.800 MHz) for cross band repeater configuration). The M/S key on the IC-910H has to be pressed to reverse the top and bottom bands before the pass for doppler correction to be done correctly. In other words, I have to ensure the downlink and uplink bands are set properly on the radio's display before the pass. This is really a problem for ISS SATGATE and automated satellite reception operation. Would really appreciate any pointers here. Thank you very much in advance. 73, Sion Chow Q. C., 9W2QC.

Re: Delfi C3 transponder frequencies ?
by Alan Cresswell 28 Jul '08

28 Jul '08

Hi David and Ib, Delfi transponder was operating over ZL on the 2132 UT pass a short while ago. Started with a 6.3kHz offset (Satellite input on 435.5495MHz, Output on 145.9068MHz). This drifted down to about a 6kHz offset at the end of the pass. Good beacon signals until Delfi was about 61 deg S when it sounded as though it was FMing and the note became rough for about 2 minutes. Little or no signal back from the transponder. It recovered before LOS a few minutes later. Note that Delfi has been in full sun for more than half its orbit before it hits ZL and progressively loses the sun before going into eclipse South of ZL so the above may not represent what happens as Delfi comes out of eclipse in the Northern hemisphere. All very interesting. Still no one to talk to in this part of the world. "Heard in VK" is the best so far. Next pass is 4 Deg low to West (over VK) so perhaps this time if the transponder is still on. Alan ZL2BX _____ From: G0MRF(a)aol.com [mailto:[email protected]] Sent: Monday, 28 July 2008 13:37 To: alancresswell(a)xtra.co.nz; oz1my(a)privat.dk Subject: Re: [amsat-bb] Re: Delfi C3 transponder frequencies ? Hi Alan / Ib I never thought I would say this.....but part of the answer is on you tube. http://www.youtube.com/watch?v=vYcl48K5qBE If you watch the video carefully, then you can see with a little stopping and starting the two frequencies on their radio when they were testing the transponder. It's about 1min 20sec into the video. 145.9005 = 435.5512 So that would seem consistent with Alan's observation and equating to a nominal clean room temperature. However, certainly seems to be that an offset has been there from the moment the transponder was finished.

Nova Frequency Tracking
by Luciano G Nachif 28 Jul '08

28 Jul '08

Could anyone on this list help me set up the Nova frequency tracking for Doppler effect compensation, please? I'm looking forward to setting that Doppler effect tracking compensation on FO-29, AO-51 and few other birds. I have read the information on the software help but got confused about frequency at the bird and at station, bird listening to you on a frequency which is lower or higher than mine and so forth... I appreciate your help! Thanks in advance, Luciano PT9KK

Delfi-N3xt
by Bruce Robertson 28 Jul '08

28 Jul '08

Gang: Just watched the excellent presentation from the Delfi team, outlining a new satellite using the 3-cube approach that they have successfully implemented in the Delfi-C3 project. They are planning a high-baud S-band downlink for burst data download and a space-weather measurement experiment. Great stuff. Once again, they want tangibly to 'give back' to the amateurs. They mentioned an improved U/V transponder like the one in Delfi-C3, but they'd also like to entertain new ideas from us. What do we think? 73, Bruce VE9QRP

FO-29 IS on over NA but no one show up!
by Luc Leblanc 27 Jul '08

27 Jul '08

I called on 3 passes today on FO-29 but no one shows up. Signal was very stable and clean but i suspect the TX was running at QRP level i only got a S2 reading with the INT preamp on on the FT-847! Anyway it's another one the be anchored on to avoid driftingachonred out of the channel. DELFI C-3 will be the next one.

FO-29 is alive and well
by i8cvs 27 Jul '08

27 Jul '08

Hi All, Following suggestions of my friend Mak, SV1BSX I tried FO-29 this night 27 july during the South bound orbit 58978 when the AOS for me in JN70ES was at 00:06 UTC and FO-29 was in sun light. I was alone into the passband and my return signal was very strong above my noise floor with appoximately only 10 watt on a 13 dBi crossed yagi RHCP / LHCP (about 200 watt EIRP) The SSB return was very clean and without FMing with the usual need to switch RHCP to LHCP time to time to get the best signal strength At 00:15 UTC FO-29 started to experience the eclipse as per InstanTrack but no signe of reduction of my return signal or FMing was noted. >From 00:15 to 00:21 until my LOS the satellite was over Africa and well in full eclipse for about 6 minutes but my own return signal was still clear ad strong without any signe of FMing so that it seems that the battery are working and as far I know the satellite performance seems to be nominal. The CW beacon was ON all the time but it should be necessary to decode the TLM to get the actual parameters ( I think IW4DVZ can do the job with his suitable software ) The transponder is very sensitive as it was as new so that refrain please to use high power because 200 watt EIRP is more than necessary. I tanks very much Mak SV1BSX for sending to me the results of his experience yesterday confirming the results that I got this night both confirming that FO-29 seems to be alive and well. We don't know what JARL did to resurrex this beautiful satellite but until she will last we have another real CW and SSB satellite to work. Congratulations to JARL 73" de i8CVS Domenico

Fox Delta ST3 problem
by morry＠tekinnovations.com.au 27 Jul '08

27 Jul '08

Hi all, I have a Fox Delta ST3 interface, and I can't get it working properly. So far I have: Adjusted the full scale on the 5500 as per the manual. Set the output adjust voltage to 4.5 (also tried 4.7) volts. When the ST3 says 360 degrees, the 5500 display says around 290. It's almost like it was not designed for a rotator that turns 450 degrees (I know this is not the case). I even set the rotor to 360 degrees and tried to adjust the output adjust voltage to get 360 on the ST3 - there was not enough range! We have two of these units and both behave the same. Our home made interface works fine! Any ideas? Morry VK4HBK

Re: Delfi C3 transponder frequencies ?
by Alan Cresswell 27 Jul '08

27 Jul '08

Hi David, The frequencies I indicated were the satellite input/output frequencies as I saw them here. My transmit and receive frequencies were those frequencies +/- Doppler It seemes to me that there is a 6kHz offset within the satellite transponder. I presume the Delfi team can tell us what the actual situation is.

Alan ZL2BX Hello Alan Hello Ib That's quite a spread of frequencies 556 to 565. Was that corrected for doppler? I suppose the other possibility is that Alan has been listening towards the end of the pass when the satellite has reached its maximum temperature and drift? This will be interesting to follow! Sorry not to see you at Surrey this year Ib. Hope everything is OK Regards David

Delfi C3 transponder frequencies ?
by OZ1MY 27 Jul '08

27 Jul '08

Hi all, The transponder was working at the pass with AOS at 0926 UTC here in Copenhagen. Had a couple of QSOs with HA2RD and PE1ITR. As far as I can make out the frequencies are different from the published ones. Just after the transponder was turned on I har to go to an uplink of 435.565 MHz to get 145.900 MHz down. This is the nominal pair I used in SatPC32. After some time had to adjust the uplink down to 435.563 MHz. Can someone confirm this ? 73 OZ1MY Ib

Something to think about! http://www.comcast.net/articles/news-science/20080726/TEC.Space.Tourism/ 73 Bob W7LRD Seattle Hi Bob. Sadly I think the general approach to Virgin Galactic's space tourism is incompaible with small satellites as we know them. The Virgin / Rutan plan takes people into space, but with zero relative velocity to the earth. This means that gravity will cause their spaceship 2 and any satellite to fall straight back down. To achieve orbit, the satellite would need propulsion capable of generating about 18,000 miles per hour of 'horizontal' motion + a bit more altitude would be nice too. Easier than launching from the earth. No friction from the atmosphere, but still a very difficult task. 73 David

Dish surface 'flatness'
by Peter Ellis 27 Jul '08

27 Jul '08

I am now the proud owner of a very 'second-hand' 3m mesh-covered skeleton dish. The mesh covering is metaphorical, rather than actual. I watched the dish on its back while as a group of small children rolled the dish back and forth and trampled holes in the mesh. That's the reason I was able to ask for it. "Please take it away," was the manager's reply to my query. Now, I need to re-mesh the dish, but I need to decide what 'flatness' ('true-ness') the surface should be. There has to be a formula, that encompasses things like: frequency of operation, curvature or focus distance, etc. I've done some looking online, but can't find it readily. Suggestions, and discussion, please? Please note: If you're going to also make product, brand name, or supplier suggestions, then be generic as suppliers and products in VK (Australia) will differ from where most list members will be sited. With thanks, Peter VK1KEP
