actuator
by w7lrd＠comcast.net 28 May '07

28 May '07

Hello Has anyone tried an actuator for an elevation? I have checked out- http://www.qsl.net/sv1bsx/actuator/actuator.html I want to add a four foot primestar to what I already have (2M 70M and a 36x30 primestar dish. With all this hardware I will be over working my g5400. I would probably have to replace the split fiberglass boom with a longer metal one. Then we get into the old metal vs insulated boom.I have some old 'C' band receivers that have actuator controls in them. -- 73 Bob W7LRD AMSAT member 28498 Seattle

RAFT Fence Doppler Plot Posted
by Robert Bruninga 28 May '07

28 May '07

RAFT-REENTRY CAMPAING web page now has a Doppler Plot against TIME: http://www.ew.usna.edu/~bruninga/craft/save-raft.html To our surprise, the RAFT XP-217 radar receiver hears the Radar sidelobes as long as it is above the horizon! I guess that makes sense for a 700 KW transmitter. Even if we are not in the 80 Meggawatt main beam, the radar receiver does still hear it (even though its RX sensitivity was intentially only designed to be only - 40 dBm? or so)... Now, is there anyone on the AMSAT-BB that would like to analyze this portion of the Doppler Plot and prove the timing. The only thing I'd like to confirm is the added inflection point at the start (probably due to the bistatic radar situation) which makes this different than the usual "S" plot with only a 3rd order curve.

PCSAT coming back first half of June?
by Joe Veldhuis 28 May '07

28 May '07

According to my tracker, PCSAT will be in full sunlight from June 2 to June 16, based on the latest keps from Spacetrack. As I understand it, the batteries on this satellite are very weak, and will not hold enough charge to support transmitting if it's eclipsed for too long, but given enough sun it is usable. This is an excellent bird when it's operational, every bit as easy to work as the ISS digipeater was, so I'm looking forward to filling in a few grids with it over the next few weeks using my modest ground station. -Joe, N8FQ Grand Haven, Michigan EN62wx

SUCCESSFUL RAFT Transponder Activation!
by Matt Bennett 28 May '07

28 May '07

Hi All, On the 0600 UTC western pass this morning (5/27), the UCISAT ground station crew successfully activated RAFT's radar transponder as it approached the Texas radar fence! After several days of unsuccessful attempts, the success of this pass was largely attributed to NORAD obtaining a fresh set of Keps for RAFT's degrading orbit just before the pass started. The epoch of the elset was less than 3 hours, so our pointing was much more accurate than in previous low EL passes. I threw together a simple website with the audio recording files and audio spectrum analysis of the transponder tone from the successful pass. The site also has tips and tricks for operators who want to help record the transmission within the footprint: http://ucisat.eng.uci.edu/RAFT.php According to Bob Bruninga (WB4APR), the audio recording on the website is in fact the transponder picking up the ground radar signal. However, he pointed out that we did not catch the narrow beam of the radar which would have sounded like a bird chirp in the middle of an open FM carrier. He believes this could be because RAFT may have been too far west of the radar station and only catching side lobes, or because the transponder was activated a bit too early (difficult to tell due to a last minute configuration change at our station to accommodate the new elset). Because of this uncertainty, we absolutely need additional operators within the eastern and western pass footprints to help record the transponder audio!! For the next couple of days, two command stations will activate the transponder just before the radar fence penetration on the eastern and western passes around 0400 and 0530 UTC respectively. These times are MUCH earlier than they were at the beginning of last week because of the orbit decay (no longer 2-4 AM). Plus, all you have to do is record the audio! If you're interested, a procedure for recording stations willing to volunteer on the website above. For specific info on RAFT and its mission/operations, please see their website at http://www.ew.usna.edu/~bruninga/craft/save-raft.html Please feel free reply with questions if you're interested in helping with the recording in the next few days and one of us will get back to you.

Uni-Trac 2003 Software Question
by Malcolm Preston 26 May '07

26 May '07

I recently purchased the unit and program from Spectrum International after my 15 year old AEA tracker box failed from salt air, Africa dust, and heat exposure here in the Virgin Islands. I get a repeated messages from the software that the keps file cannot be accessed although the file is installed in the same directory as the program and the Main Configuration file set-up is as shown in the manual. Has anyone experienced this? I've tried everything I can think of to make it work - new 2line kep file, putting it in another directory and referencing it, downloading and re installing the program. The program does sometimes show the azimuth and elev of a bird and the G5400B but beyond that it doesn't work. Can anyone out there give me a clue? Will the box interface with NOVA or SatPC32 even though the Uni-Trac program doesn't work? Malcolm Preston, NP2L St. John, US Virgin Islands

Mode V/S AO-51
by DeYoung James 26 May '07

26 May '07

Greetings, Thanks to all who contributed useful comments to my previous V/S message. The second evening's passes I was able to confirm that all is working, however my tall, nearby, local trees are not conducive to passing the S-band frequencies, so in future I will have to go portable. The good thing is that very little QRM (at least on AO-51's downlink freuquency, but not so the BB!) was/has been observed here inside the DC beltway which makes me think that P3E and Eagle's S-band payloads will be usable just fine. 73, KG4QWC ____________________________________________________________________________________Get the free Yahoo! toolbar and rest assured with the added security of spyware protection. http://new.toolbar.yahoo.com/toolbar/features/norton/index.php

Horizontal Polarized Antenna
by Sion Chow Q. C. (9W2QC) 26 May '07

26 May '07

Dear All, Currently for my satellite station I am using double stacked vertical polarized yagi antennas for 2M and 70 CM. However, due to mounting constrains, I would like to mount them in a H configuration instead, on the G-5500 rotator, with the 2M antenna on one side and the 70 cm antenna on the other. A yagi for L and S band will be mounted in between the two antennas on the horizontal boom. This would mean that I will require the antenna to be horizontally polarized instead of vertically polarized unless I use a non-metallic boom. Before I perform this, I would like to know what are the differences with using horizontal instead of vertical polarization when operation the LEOs such as AO-51, SO-50 and etc. Also, what are the effects of using a horizontal polarization with the ISS on 2M? Sorry if this has been asked before, but was just trying to be sure before I perform any major modifications. Thank you very much in advance. 73, Sion Chow Q. C., 9W2QC.

RAFT Commanding needs Doppler compensation !
by hamoen＠iae.nl 26 May '07

26 May '07

Dear RAFT voluteers in the Southern US, Key is the awareness of the need for doppler compensation: memory A approaching - 145.827 receive / 145.823 transmit memory B overhead - 145.825 receive and transmit memory C going away - 145.823 receive / 145.828 transmit Most of you know, but you easily overlook a first time and you have only one or two passes left ... I have always simply used 3 memory channels, in fact mostly channels A and C, due to the speed of RAFT (same holds for ANDE). Worked flawless for commanding RAFT. Without compensation it won't work though :-) Success ! Henk, PA3GUO, RAFT Command Station, The Netherlands, Europe

--- Original Message --- > This mode is a real kick. With only a few on the satellite we can > actually say something, beyond a grid square.-- > 73 Bob W7LRD Hi Bob (and the list), Yes, it's a great mode, and it'd be great to see in the schedule more often. I powered up my old Cal Amp integrated downconverter/antenna last night for the first time in a long while! I worked a couple stations in this mode, although I ran into some problems and couldn't return a call or two that I heard. It was purely operator error, as I was outsmarted by my PC! Instead of creating a new mode in InstantTune for the 145.880 uplink, I attempted to override the PC control.. No dice, on each frequency update the TX rig returned to 145.920, just like it's supposed to do.. I know AA2TX is laughing at me about now! Does CAT mean 'Computer Aggravated Tuning'? hi hi The bird was loud and clear, and signals were quite strong at my QTH, although the QSB is very apparent. Next time I'll be ready for a full-blown QSO! 73, Kyle Yoksh KØKN Olathe, Kansas Amsat # 35249 VUCC Satellite # 150

Dayton Jump Kit
by Robert Bruninga 25 May '07

25 May '07

At Dayton, Mendlesons was selling 12 VDC Jump Start 12VDC battery sets with 400W inverters for $10 AS-IS (something wrong with each). But the 18 AH battery was worth it alone.... I bought two. For one, I just charged the battery, and left the blown fuses in the AC inverter. Everything else worked. The inverter was smoked and so I wont use that feature. For B. The 400W AC inverter worked, but the DC switch panel didn't and left a constant load on the battery. So the hack shown on this web page made for a 10 minute bypassing of the switch panel while letting everything else work properly. See http://www.ew.usna.edu/~bruninga/DaytonJunk.GIF They were selling them by the dozens. Thought someone else might find this useful. Bob

> Can you explain what happened with last night's pass? > I see a frowney face on the web page... http://www.ew.usna.edu/~bruninga/craft/save-raft.html Well, lots of -sleep was invested by several people, and a good effort was made. I am very encouraged by the efforts of these volunteers! Being the first attempt by both stations, there were lessons learned. I think they are going to try again tonight... But we do want to welcome backups to join the team. Especially those that have done a remote-logon to a KPC-3+ TNC before. The web page tells all about how to do it. But we must coordinate so that only the best available station makes the attempt each pass. Ill try to keep the web page up to date in real time. Bob, WB4APR

Thanks for Dayton Demos
by Keith D. Pugh 25 May '07

25 May '07

All, I want to thank everyone who participated in the recent Satellite Demonstrations at the Dayton Hamvention. We did successful demos on AO-51, AO-07, and VO-52. Friday was a slow day, but Saturday and Sunday made up for it. The demos were well attended at Dayton and we received many kind "thank yous." 73 - Keith, W5IU

When I refer to 1296 or 1268.. I think 1.2gig, not a Letter like S, X, K, what have you. I need a little help or a link to a list that breaks down what band is L/S/U/K/V/ ect. I looked on the amsat page.. but could not find anything. In time ill memorize it.. but when trying to think of future plans for my station and doing my research.. the use of both is so common.. its confusing trying to figure out my needs.

Stupidity Proof
by Reicher, James 24 May '07

24 May '07

Monsieur LeBlanc, Here's my response to your baseless and (as usual) paranoid schizophrenic accusations: 1. "Lived in a free America..." You don't. You live in Canada. Quebec, to be precise. 2. "... president Hambly and the BOD dont like to be disclose even the truth..." On the contrary, I find that the Board of Directors has regularly been most truthful and forthcoming with information, especially when asked about it in a tactful and polite manner. 3. "Dont support an anti democratic organisation could be a general side service note to NASA and the US government will be a sound advice to give now." No one ever said this was a democratic organization. On the contrary, this is a corporation. It is governed by a board of directors who are elected to guide the group to the betterment of the satellite community. Under the by-laws, the Directors are under no obligation to listen to any one individual, or even a particular group, other than the regular elections. I have found that the Directors have generally been most responsive to questions and suggestions when they are asked in an intelligent and polite manner. 4. "Have any suggestions i am now freely open...as AMSAT-NA IS ATTACKING MY RIGHTS." You have no rights on this reflector. It is governed, supported, and operated by AMSAT. You HAD been granted the PRIVILEGE of posting here, until your abusive actions and postings generated such an outcry among the great majority of the group that your PRIVILEGE was revoked. Your right to say what you want has not been attacked, you can still say it. You just don't have the PRIVILEGE to abuse the assets of other people to make that statement. You want to post it to others? Fine! Get your own reflector. 5. "It is not the class of license the amateur holds, but the class of the amateur that holds the license." You've proved time and time again, that you have no class. 73 de N8AU, Jim in Raymore, MO Light travels faster than sound... This is why some people appear bright until you hear them speak.

CP4 Update
by Keith McCabe 24 May '07

24 May '07

Hi all, Just to let you know, Cal Poly recently used the SRI dish to uplink to CP4. We have (supposedly) put it into Normal Ops, meaning it should be beaconing at 2 minute intervals, instead of the old 5 minute intervals. Any reports as to whether this is correct would be great. We really appreciate the support from everyone so far, thanks a bunch! -- Keith McCabe, KI6CWF PolySat, Cal Poly State University

Greetings, I was listening to 2.4012-GHz +/- doppler FM-mode with my K5GNA/AIDC downconverter at the focus of a Starband .75-m x 1.0-m ellptical dish, I never heard myself (145.88-MHz up) but transmitted only a few times. However, I did hear strong "digital" signals at max. EL. for about 30-s on two passes last evening and fairly strong quieting at times. No voices heard at all, however. I have heard nothing but white noise monitoring 2.4012-GHz when AO-51 is below the horizon so pretty sure it was AO-51 and not terrestrial. Without a regular beacon signal in space it is very hard to be sure if all my equipment is working, however. I do have a Gardiner down-converter 2.4-GHz signal source so pretty sure my LO value is correct to a few KHz. Anybody willing to admit to Tx'ing digital or anything else last evening on east-coast U.S. passes to confirm that my 2.4-GHz equipment is really working? 73, KG4QWC (FM18) ____________________________________________________________________________________Get the Yahoo! toolbar and be alerted to new email wherever you're surfing. http://new.toolbar.yahoo.com/toolbar/features/mail/index.php

Re: ROTOR INTERFACES--HEEELP

Hi Pete, I am using two different boards with great success and ease of use for Nova, SatPC etc. The first board is from EA4TX. Go to his website at: http://www.ea4tx.com/ Comes assembled and needs a parallel port on your computer (printer port), which is also the biggest disadvantage especially for newer laptops. Is not too expensive and the service and support is outstanding. Needs external power supply. The second board is the LVB tracker (see current discussions on the mailing list). Can be ordered directly from AMSAT-UK and soon from AMSA NA (contact Gould Smith for available boards ect.), needs assembly and can be used with an USB or serial port. Excellent quality kit and dreat design. I use it mobile. Power is supplied from the rotor control box. Hope this helps.

RAFT Packet Operator assistance Desparately needed
by Robert Bruninga 24 May '07

24 May '07

We desperately need some AMSAT OSCAR class stations in the Central USA to complete the RAFT radar fence test ASAP. Deorbit is in the next two weeks, much earlier than previous predictions, and so we will not get another comfortable evening pass window. Prime passes now are occurring around 4 AM and moving earlier (sorry). Before, we asked for Southern USA. Now we realize that someone in most central states have command potential. Anyone within about 1000 miles E/W of North Texas or 600 miles north and south are ideal! Station requirements: 1) OSCAR class tracking 2m beam for up/downlink 145.825 2) Standard AX.25 1200 baud packet 3) Simple HYPERTERM text commanding 4) Familiarity with TNC's and TNC commanding 5) Prepared to record 1 minute of audio heard on downlink Unfortunately I am going to Dayton this weekend, but we have to really be ready for this next week and get this test done. None of the principals involved in this design can do it because we all live too far away from the 216.98 MHz RADAR fence transmitter in North Texas. See WEB: http://www.ew.usna.edu/~bruninga/ande-raft-ops.html Thanks, WB4APR, Bob -----Original Message----- Sent: Tuesday, April 24, 2007 1:23 PM Subject: RE: [amsat-bb] RAFT Packet Operator assistance needed We only have 7 days left in this operating period and really do need a good OSCAR station in the Southern USA in a line from AZ to GA to conduct this test of RAFT flying through the 80 megawatt radar transmitter beam originated in north Texas. There is only one viable pass per day per command station location in the early evening.... The trick is to command the satellite to turn on its downlink carrier and Radar receiver exactly 30 seconds prior to passing through the fence and then having an audio recorder running to "hear" (record) the tone when we pass through the radar beam. Commands are a simple CONNECT XXXX at the cmd: propt, then an exchange of passwords, and then sending a simple typed command at the right time. RAFT can he HEARD just fine on ALL FIVE passes leading up to this last pass per day, so you can test your RECEIVE capability on any pass, but can only command in the dark (due to overcharging on batteries makes uplink receier deaf)... If anyone can conduct this test please let us know. Only one person per pass can attempt this, so we want the best gun at the stick. Fully conversent at the TNC "cmd:" prompt and preerably with experimence with the KPC3+ remote-sysop command mode.

Get your AO51 mode requests in!
by Andrew Glasbrenner 22 May '07

22 May '07

I've put together a preliminary schedule for June, so if you have any further requests please get them to ao51-modes(a)amsat.org in the next 48 hours or so. I have requests for 2 different hamfests, the ARRL Kids Day event, and of course Field Day. I expect to have the schedule posted for June by this weekend. We may run some more L/U on 435.150 along with the normal repeater for FD practice at the end of this month also. 73, Drew KO4MA AMSAT-NA VP, Operations

LVB Tracker boards and boxes
by Gould Smith 22 May '07

22 May '07

Hello All, Howard Long's LVB Tracker boards were a huge success at Dayton. We are exploring offering more options in response to requests from people in Dayton. Possible combinations are: 1) bare board with info CD 2) board and parts kit w/ LCD 3) built board 4) built board in an enclosure So, what I need is feedback on what the satellite users would rather have. The bare main board/CD would be probably $25 Parts kit around $75 Parts kit plus the board/CD around $100 Built board around $120 Unit in enclosure around $150 These are approximate prices, we need to explore further what the final cost will be. We will decide what to offer depending upon the responses received. Let me know what you would like to have available. 73, Gould, WA4SXM wa4sxm(a)amsat.org

Epoch time of Keplerian elements.
by HEYLER YESID LEDEZMA LEUDO 22 May '07

22 May '07

Hi. Excuse me for my defective English. One more time I write for ask you something about keplerian elements: ¿The epoch time calculated in Keplerian Elements is a Julian date or is a Gregorian date?. I think than is a Greogorian date, but I am not sure. Thanks for your information. Heiler Yesid Ledezma Leudo. Investigador: Proyecto Espacial Colombiane Órbita Heiler Yesid Ledezma Leudo.

TE Systems Amplifiers
by Jim Jerzycke 22 May '07

22 May '07

Greetings all I picked up two TE systems amps at my club's white elephant sale, and don't know much about them. I can't seem to find a TE Systems website, and haven't had time to look through my old QSTs for an ad so I can tell what drive levels and power output these produce. Does anybody know of a site that has the specs for these? 2M amp: 1412G 70cm amp: 4412G tnx es 73, Jim KQ6EA

75 ohm CATV Cable on 70 cm
by Fred A Parker 22 May '07

22 May '07

That is what I use. I use it nearly exclusively for my complete station. Have to use crimp on connecters because it has aluminum shield. If it gives me any mismatch I just trim the length. Remember if the feed line is cut to an electrical half length the input impedance equals the output impedance. The stuff I use I purchase from a local hardware store. It is sold for satellite TV hookup and is rated for up 2.5 GHZ. Cost locally is about .10 cents a foot. Just do not try and use high power while transmitting with it. Fred (KF0AK)

Re: 75 ohm CATV Cable on 70 cm
by Fred A Parker 22 May '07

22 May '07

I run up to 100 watts with no trouble. To get a good match. Put a dummy load on the end of the cable and keep trimming it say six inches at a time until you get a good match . Remember if the cable is cut to 1/4 wave length or odd multiple thereof it is the worst condition you can have. While 1/2 wave length or even multiple thereof is ideal. Or you could try and put some torrid beads on the end of it to help control the rf feedback back down the line. Remember this line is not designed for the high voltages you get with high swr.

Yaesu G-450 Computer Interface
by Sion Chow Q. C. (9W2QC) 21 May '07

21 May '07

Dear All, I have an old Yaesu G-450 rotator that I plan to put into use by mounting a rotary dipole for 10M terrestrial and satellite use. However, this rotator does not have any form of computer interface. There seems to be a few third party solutions to this problem but however, before I make a decision, I would like to know what the community has been using. Also how well will a rotary dipole work with the Mode-A satellites such as AO-7? Of course it can only track the satellite in azimuth. Thank you very much in advance. 73, Sion Chow Q. C., 9W2QC.

WA8SME Antenna controller for G-5500, G-5400, NOVA, AND SatPC32
by Dan 20 May '07

20 May '07

Has anyone had success with building WA8SME's antenna controller that was featured in Amsat Journal recently and used the board from Far Circuits? Any troubleshooting tips (voltage or resistance levels) would be appreciated. Far circuits has made the board layout different and I have found a few mistakes, but don't know if I found them all. When I have it hooked up using a 5400 rotor and Nova the down led lights when I start the autotracking in Nova but nothing else happens. The Data LED never does light.

Re: Tower suggestions....

> I'm considering mounting the tower on my deck which is made from 2" x 6" > decking with 2" x 8" rafters on 24" centers. > <snip> > Does this sound feasible or am I gambling? Rod - Let me ask you two+ questions: 1. Is this configuration included in any installation guidance issued by Rohn? 2. Are you required to get a building permit? If so, what documentation are you required to provide in terms of plans, engineering drawings, and loads analysis? If the answer to #1 is yes, then you're in the clear. Follow Rohn's directions and you're fine. If the answer to #1 is no, and #2 is yes, you might find that you may have to provide details that would PROVE that your installation is safe. (This is in contrast to an installation that exactly matches a recommended Rohn configuration, where you could reuse their canned analysis for permit purposes.) And unless you are a professional engineer (or you know one who will work pro bono), your savings of two sections of tower may pale in comparison to the cost of a PE's time to do the required analysis. And even if the answer to both questions is no, it would probably STILL be a good idea to get someone knowledgeable to review the analysis and see if it makes sense. You might find someone on this list that could do that, but I'm not sure I'd "gamble" (your word) my house on a guess or back-of-the-envelope calculation. Good luck. 73, Steve W3HF P.S. I'm NOT a mechanical engineer. But I did take mechanics classes when I got my EE degree 28 years ago, and I did pass the first half of the NY state PE exam back then. And I personally don't think that 2x6 decking on 24" centers would be enough to safely mount the base of a 20-30 foot tower made of Rohn 45G. After all, any lateral loads would be braced by only a few 16d nails or 3" screws, the ones that hold the decking to the joists. (They're called rafters in a roof, but joists in a floor.) But I have NOT done the calculations, and would welcome the inputs of someone who is more qualified to analyze this.

WD9EWK from DM34/DM44, 13 May 2007
by Patrick STODDARD (WD9EWK/VA7EWK) 17 May '07

17 May '07

Hi! After a few days, I have been able to sit down and download pictures from my camera, audio from my recorder, make some MP3 files of those audio recordings, and log my contacts from that Sunday trip I just took to northern Arizona. It was a fun drive, making 24 contacts from 3 different locations during 5 different passes (2 on AO-51, 2 on SO-50, 1 on AO-27) throughout the day. First stop, DM34we (34.184433 N 112.134783 W, 3400 feet/1036m elevation) After leaving home at 0645 local (1345 UTC), I drove north to a freeway rest area on the edge of a valley about 50 miles/80km north of Phoenix on the I-17 freeway. This rest area, at Sunset Point, has a good view of the sky in all directions, and was about 12 miles/20km north of the DM33/DM34 boundary so I could start my operating from DM34. You can see a map with photo from Google Maps of this location at: http://maps.google.com/maps?f=q&hl=en&q=34.184433333+n+\ 112.134783333+w&ie=UTF8&ll=34.195617,-112.116938&spn=\ 0.050618,0.065489&t=h&z=14&om=0 I parked at the south end of the parking lot, so the back of my wife's truck was pointing northeast - perfect for the upcoming SO-50 pass. The pass, at 1444-1458 UTC, was a nice one to start with. It had a maximum elevation of 38 degrees, going from north to southeast, and I hoped that would bring more than 1 or 2 contacts to start the morning. It did - 5 contacts (W6ZQ in Arizona, N5AFV in Texas, and 3 Mexican stations - XE2HWB, XE2MWY, XE2WY). Once the pass ended, I packed up my stuff and drove about 25 miles/40km further north for more fun. DM34xm/DM44am (34.51875 N 112.0 W, 4455 feet/1358m elevation) This was the area I had identified previously as a good spot I could drive to and operate from both of these grids at once. It was a little more than 1/2 mile/1km west of the I-17 freeway, and north of Arizona route 169, just inside the boundary of the Prescott National Forest. For those not familiar with Arizona, a forest at this elevation has few trees. I was able to follow a dirt track north from route 169 that turned east and let me park at this spot away from the highways and have a good view of the sky. A map with photo of this location is at: http://maps.google.com/maps?f=q&hl=en&q=34.51875+n+\ 112.0+w&ie=UTF8&ll=34.518898,-111.9942&spn=\ 0.025211,0.032744&t=h&z=15&om=0 Since I didn't have plans for lunch until 2100 UTC, I knew I could spend the morning playing radio on my way to lunch. I arrived at this spot about 20 minutes before the first AO-51 pass I could work at 1541-1556 UTC, confirmed the location with my GPS receiver and took a couple of photos of the display showing 112 degrees West exactly, and set up my equipment. The first AO-51 pass, toward my east, was the busiest pass of the 5 I worked. This was also the pass with the highest elevation, at 62 degrees. I made contacts with 9 USA stations and 2 Mexican stations during this pass. All of those contacts were in the first half of the 15-minute pass, and I did not hear any other stations come on for the last half. Oh well... it was fun to get on and help others put these grids into their satellite logs. About 30 minutes later, I had an SO-50 pass that went to the west of me between 1625 and 1638 UTC. It was a 20-degree pass, and I figured that there would be only a few showing up on there. Unfortunately, I was right - Mark WA8SME in California and Bernardo XE2HWB in southern Baja California were the only 2 I heard during the entire pass. I worked them both, then waited for the final AO-51 pass of the morning I'd work from this location. When AO-51 returned for a pass at 1721-1733 UTC, it was only up at 14 degrees maximum elevation. Not an impossible pass to work, but one that would probably have few stations show up. After a couple of minutes, I work Dino VE7XDT near Vancouver. Dino was demonstrating satellite operating at a swap meet, and I was happy to say "hello" to him and his group there. I made contacts with 4 more stations in Idaho, California, and Washington state to complete this pass. After these passes, I drove across to Payson - a small city about 90 miles/145km northeast of Phoenix - for lunch. After lunch, I saw that I had time to work an AO-27 pass on my drive back to Phoenix. This pass was a "bonus", as I had not previously announced any plans to work afternoon passes on this day. DM44ha (34.0347 N 111.365866667 W, 3196 feet/974m elevation) This location was another highway rest area, at the junction of two Arizona state routes (87 and 188) about 15 miles/25km south of Payson on the way back to Phoenix. I had quickly driven to the DM43/DM44 boundary, but there were too many mountains to the west so close to that spot I decided not to try working AO-27 from there. This rest area is about 3 miles/5km north of the DM43/DM44 boundary, but with a better view of the western sky. You may see a map with aerial photo of the location at: http://maps.google.com/maps?f=q&hl=en&q=34.0347+n+\ 111.365866667+w&ie=UTF8&t=h&z=13&om=0 Along with running my PREDICT program, I used the Java applet from the AO-27 web site http://www.ao27.org/ to know the approximate time the AO-27 repeater would switch on for the pass I could work. The start time was 2315 UTC, and I was ready to go. Or so I thought. I knew that the AO-27 timer is not the most accurate timepiece. I expected that it would turn the repeater on a little early, but I think I missed the first 30 seconds. There were some high moutains southwest of me, and I think I might not have been pointing at the satellite accurately. Once I heard Mark WA8SME on there, I called him and made another contact with him. Nobody else showed up during the pass, even when we would take breaks to invite others to join, so we chatted until the repeater switched off at 2322 UTC. Only one contact during the pass, but better than nothing. Recap Overall, I made a total of 24 contacts on 5 different passes. I worked stations in 10 US states, 1 Canadian province, 4 Mexican states, and a total of 18 grids. I made 7 contacts on 2 SO-50 passes, 16 contacts on 2 AO-51 passes, and 1 contact on the AO-27 pass I worked later in the day. Maybe not a large number of contacts, but 11 on one AO-51 pass was pretty good. With the hot weather in the deserts of central and southern Arizona during the summertime, I hope to be able to repeat trips like this and possibly to some other grids further north. I have posted photos from the first two stops I made, along with MP3 recordings of the passes I worked from those locations, on some free web space I have. You can find those files at: http://www.geocities.com/xe2wd9ewk/20070513-DM34_DM44/ Since this is free web space, Geocities will enforce hourly bandwidth restrictions. If you have difficulties in accessing those MP3s or photos, please e-mail me directly and I would be happy to send you any of those files. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Indoor tracking at Dayton!
by Robert Bruninga 17 May '07

17 May '07

Use your D7 to find each other at Dayton, anytime, anywhere, including indoor. No GPS dongle needed. The D7 and APRS is not just GPS! The only people who need GPS are those that are lost or moving. Use your D7. Put something useful in it. It can hold three posits as is, and it only takes a tweak of 2 digits to put yourself anywhere within the HAMvention complex or Dayton area... Just take a note card with your favorite locations in and around Dayton where you will be hanging out and manually enter your posit when you sit down for a while. Your favorite bar, restaurant, motel, meeting, etc. Here are some examples on the grounds of the Hamvention: Basic HARA posit is 3949.yyN and 08415.xxW Then tweak the X and Y digits whenever you hang out in one of these rooms. This list proceeds diagonally from the front Traffic light to the extreme NW corner of the Hamvention fleamarket/parking area. In fact, cut this out and tape on the back of your HT: 3949.yyN/08415.xxW yy/xx Location ----- ---------- 19,24 Traffic light 23,28 East Hall 23,33 Ballarena 26,33 Food court 26,37 Forum rooms 27,32 North Hall 29,38 Arena 36,62 Extreme NW corner of the Flea Market/parking lot area 3946.87N/8406.60W TAPR/AMSAT meeting at AF museum Anywhere in between is trival to estimate using the above figures assuming you have even a basic sense of direction.. Each hundredths digit is 60 feet. Trying to find someone? Just enter your estimated posit above, and then your D7 will show you the distance and range to them (if they are updating). Don't just leave some stupid old posit in your D7 that has nothing to do with reality. If nothing else, enter 3949.2-N and 08415.3-W and set position ambiguity to 1 digit, and this will show the world that you are basically inside the building complex. See ya there. On the road enroute Thursday afternoon. Bob, WB4APR

Re: Mini-DXpedition to Santa Catalina Island (DM03/IOTA NA-066)
by John Mock KD6PAG 16 May '07

16 May '07

I returned a couple of days before the fire started and as of today, 30+ cards have been mailed. Aside from cards to Mexico, any that have not gone out yet have at least been sent e-mail. Aside from the usual problems with weekend AO-51 passes (especially in the morning), things went pretty smoothly, aside from a couple of minor equipment glitches. The Pacific/Mountain zone folks seemed to be good about not crowding the transcontinental passes. Pacific passes were lighter than i would like but still productive, and alas, i missed hearing several West Coast stations that i would have liked to have worked. Local geography made Hawaii passes impractical but at least i worked one Alaska station. So after a week or so, if you haven't gotten a card or an e-mail from me, please send me an e-mail with the particulars of the contact and i will get a card out to you (assuming i have you in my log and/or voice recordings), and as noted before, SASE not necessary. 73's and good luck! -- KD6PAG (Networking Old-Timer, Satellite QRPer) P.S. Next unusual grid should be a couple of AO-27 passes from CM86 (Santa Cruz) on Saturday afternoon, 2 June 2007. Possibly also CM79 in late June, weather and schedules permitting. P.P.S Reminder: US postal rates have gone up again; they are now $0.69 for Canada and Mexico, $0.41 domestic. If anyone who sends SASE wants to trade some Canadian or Mexican stamps for US stamps, please let me know. (If i get more requests than i can use, perhaps i'll facilitate set up some kind of stamp exchange.)

OSCAR-11 Report
by Clive Wallis 16 May '07

16 May '07

OSCAR-11 REPORT 16 May 2007 RECEPTION REPORTS REQUESTED! OSCAR-11 might switch ON around 18/19 May and possibly 8/9 June. However, due to solar eclipses the satellite is likely to switch OFF, almost immediately, probably after less that one orbit. This brief period of activity could occur when the satellite is over any part of the world. Due to the condition of the satellite, there is no guarantee that these predictions are reliable, during the eclipse season. Any reception reports would be grately appreciated. Please send to the the address below or post to amsat-bb. If you are able to record the satellite as a WAV file, please do so, but let me know what you have, before sending it! If you need to hear what the satellite sounds like, please visit my website www.users.zetnet.co.uk/clivew/ The satellite transmits on 145.826 MHz. set receiver to NBFM. --------- During the period 17 April to 15 May 2007, the satellite's 145.826 MHz. beacon was heard from 22 to 28 April. The beacon switched ON as expected. This short period was of special interest since the solar eclipses started on 21 April and steadily increased each day, reaching a duration of 12.6 minutes when the beacon switched OFF. Thus it was an rare oportunity to study the effect of solar eclipses on the satellite. Good signals were heard on most passes, although they became weaker towards the end of the ON period. Good copy of the telemetry was obtained. The on-board clock has continued to be of interest. At the start of this ON period the clock was 38.21438 days slow, showing a loss of about 3 seconds since the previous ON period. For the next four days the clock remained stable, however by 07:14 UTC 28 April the clock had lost a further 220 minutes. On the next two passes the clock lost 20.3 and 20.6 minutes respectively, ie. almost twice the duration of the eclipses. When last heard the total clock error was 38.39593 days slow. Peter, ZL3TC reported hearing the satellite switch ON, after coming out of eclipse at 08:14 on 28 April. These observations suggest that the satellite's electronics may be suffering from low power supplies, before the watchgog timer cycle finally resets. If the satellite's watchdog timer continues to operate normally, the beacon should switch ON around 19 May 2007. However, the duration of the solar eclipses at that time is 23.4 minutes. This could cause the beacon to switch OFF. after a short time, probably less than one orbit. This short transmission could occur any where over the world, and could be repeated at 20.7 day intervals, until August when longer transmissions are likely. expected to start on 20 April and will continue until 20 August. If the satellite performs as it did last year, it is unlikely to be heard, for any length of time, during the eclipse season. Maximum eclipse duration of 23 minutes occurs on 14 June and it decreases to 12 minutes by 10 August. At that level, the satellite might start transmitting. I am indebted to Ian ZL1AOX, Peter ZL3TC, David G8OQW, Jeff KB2M, Edward BX1AD, Sil ZL2CIA, Gene Dave G1OCN, John K8YSE and Grant VK4JAZ for their reports. Many thanks. The current status of the satellite, is that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 are still working. The real time clock is showing a large accumulated error, although over short periods timekeeping is accurate to a few seconds per month. The day of the month has a bit stuck at 'one' so the day of the month is showing an error of +40 days. The time display has switched into 12 hour mode, with the date changing at around 09 hours UTC. Unfortunately, there is no AM/PM indicator, since the time display format was designed for 24 hour mode. The spacecraft computer and active attitude control system have switched OFF, ie. the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed. When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus. After 22 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude. The watchdog timer now operates on a 20 day cycle. The ON/OFF times have tended to be very consistent. The average of many observations show this to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website. If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear. The website contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry.
