Wanted: VIDEO astronaut McArthur at AMSAT Symposium!!
by Cor 01 Oct '06

01 Oct '06

Hello All, Astronaut McArthur is invited for the Amsat symposium in San Fransisco. http://www.amsat.org/amsat-new/symposium/2006Keynote.php McArthur shall talk about his amateur radio adventures during his mission in the ISS Space Station. http://spaceflight1.nasa.gov/gallery/images/station/crew-12/inflight/ndxpag… McArthur worked 130 DXCC countries, and all states (WAS) of America. http://www.arrl.org/news/stories/2006/06/01/103/?nc=1 Sadly I can not join the Amsat symposium. I wonder if there is someone who can record (good quality) VIDEO + AUDIO during McArthur his speech. After the Amsat symposium I hope someone can send me the video on a CDROM so I can also put the video on my website where everyone can download the video. Keep in mind: McArthur his mission was an unique event for thousands of hams all over the world!!! (keep something from the history saved for the future!!!). In the past we helped McArthur with our NA1SS DXCC campaign. We have encouraged many (also rare) DXCC countries and asked them (via e-mail) to trie McArthur NA1SS. It was a great success, after many hams have sended enthusiast e-mails and were proud of their contact with an astronaut in a Space Station, some hams came from rare DXCC countries (or continents) where noone ever have made a contact with a Space Station before. Look here NA1SS worked DXCC´s: http://www.issfanclub.com/dxcc In case you want to record McArthur on VIDEO + AUDIO please let me know!!! Send an e-mail to: isszarya(a)hotmail.com 73's Cor PD0RKC ISS info: http://www.pd0rkc.com

How to decode the sound of HITSAT FM on MixW2
by Mineo Wakita 01 Oct '06

01 Oct '06

I was successful in the decode the header of HITSAT FM 437.425MHz packet data. These signals were switched on ONLY in the range of Japan. And these 1k2 AFSK (FM 437.425 MHz) be able to decode by modem of IC FX614, becauce NOT AX.25 (not NRZ-NRZI). I was successful in the decode of the header "JR8YJT" of these FM data by using a soundcard program MixW2 (ver2.17). > JR8YJT#!5020000100927205504,305,366,8;7A,34,388,99,2,5,8C,12D 1. Click_right the volume button on your PC. 2. Click the adjustment of Audio_property. 3. Click the audio tab. 4. Click the volume button of the audio record. 5. Check the button of the monaural mixer. 6. Run MixW2. 7. Mode - RTTY 8. Mode - Mode Settings - Check "Inverted, AFC, and Squelch" 9. Mode - Mode Settings - Input "1800" Hz in TX and RX frequency box 10. Mode - Mode Settings - Input "Single filter" in Demodulator box 11. Mode - Mode Settings - Input "1800" in Shift box and Baud rate box 12. Mode - Mode Settings - Select "ASCII 7" 13. Run Sound_Decoder "sndrec32.exe". 14 Playback "60928hit.wav" in the following URL. 15. http://www.ne.jp/asahi/hamradio/je9pel/hitsat03.htm 16. Then the signals are decoded automatically on MixW2 window.

70cm preamp
by Bill Bruno 30 Sep '06

30 Sep '06

On my V/U setup I have a SP7000 70cm preamp. Working FO29(JAS2) my 2 meter signal overloads the preamp, my signal splattering like an adjacent strong station. With preamp off the problem is not there. In testing I found the overload happens in any combination of 70cm 2m frequency pairs. I can eliminate the problem by lowering the tx power, but by doing so I have a hard time copying my own signal. How can I eliminate the 2m sig overloading the preamp while still maintaining adequate power? Antennas m2 436cp30, Gulf Alpha 2m5el, both right hand polarization. I could use some suggestions. Thanks Bill

W0LMD also has a nice patch feed for 1.2 GHz / 2.4 GHz http://www.ultimatecharger.com/Dish_Feed_SL.html Here are step-by-step pictorial instructions on contructing this patch feed using ordinary hand tools: http://www.qsl.net/kd6pag/LS-patch-feed.html My metalworking skill are such that if i can make one of these things, then you probably can, too.

L/S antenna redseign
by w7lrd＠comcast.net 30 Sep '06

30 Sep '06

Hello Bob is planning a new L/S redesign. Before I pick up my hack saw I would like some opinions/advice etc. The dish-a 54X48 inch prime star. The feed -a short helix for L & S side by side in line with the fan pattern. I beleieve W0LMD tried co-wound helixes with mixed results. On the same boom is a 2M & 70cm yagi. With all this antenna and counter weight is it too much for my G5400 elevation rotor? Plan "B"- use a actuator similar as described in http://www.qsl.net/sv1bsx/actuator/actuator.html . I have some actuators and a lot of hacksaws and I'm not afraid to use them. With only 10watts and some hardline I feel this dish might be necessary for a HEO on L band, and I might as well use it on S. I also have a 12foot TVRO but that's another story (project) for another day. As always your opinions/advice even ridicule is appreciated. 73 Bob W7LRD Seattle

If you mount them side by side, there will be a compromise as there is only one focal point. The concentric feed can be made to work as long as you have some filters to keep the 1.3G signal out of the 2.4G RX.

Hello BB, I will be doing a talk/demonstration Saturday, 30 September at the Ten-Tec Factory Hamfest. There is an AO-7 pass 1320-1340Z and I will be using a 2M antenna, downconverter and HF rig with spectrum display. I would appreciate some calls during the pass, voice and CW to show off the signals and activity level. I won't have an uplink, so can't reply. Looking forward to hearing a lot of activity tomorrow morning. Thanks, Gould, WA4SXM

Re: YES !! RS-15 is alive !
by Matt 29 Sep '06

29 Sep '06

Beacon was quite strong last night (RS-15 was in sunlight). All the beacon did was to send a carrier every 4 and half seconds that lasted for 1 second, and it shifted in freq down by about 100 Hz (watched it on Spectran). The freq shift I guess is from not having enough power to drive everything. Beacon comes on - transponder comes on - satellite dies - beacon comes on - transponder etc....... I tried to uplink with as much grunt as I can muster, 100w into 22 ele X yagi switchable, but nothing. I'll have a few more shots at it and see how it goes. >YES !!

ARISS Contacts During JOTA

Is there anyway that ARISS can be availble for general astronaut contacts on 10/21-10/22 for JOTA? I am going to be operating W9W that weekend with my troop. Based upon the latest Keplian Elements, these times seem to be favorable for all of the United States on 10/21-10/22: 10/21: 0522Z to 0542Z 0658Z to 0718Z 2325Z to 2341Z 10/22: 0059Z-0118z 0234Z to 0254Z 0544z to 0606z This is the prediction for Chicago IL: 2006-10-21 00:29:42 ISS 307.7 0.0 ecl 2164 357.4 -58.8 2006-10-21 00:34:36 ISS 29.5 43.6 ecl 475 359.7 -58.8 2006-10-21 00:39:29 ISS 112.0 0.0 ecl 2153 2.0 -58.8 2006-10-21 02:04:57 ISS 291.8 0.0 ecl 2160 38.7 -53.1 2006-10-21 02:09:26 ISS 226.3 16.8 ecl 945 40.3 -52.6 2006-10-21 02:13:54 ISS 160.5 0.0 ecl 2148 41.9 -52.0 2006-10-21 16:56:29 ISS 173.1 0.0 2.5 2172 245.1 10.4 2006-10-21 17:00:00 ISS 127.6 5.9 1.5 1563 245.7 9.8 2006-10-21 17:03:31 ISS 82.3 0.0 2.0 2177 246.4 9.2 2006-10-21 18:29:31 ISS 228.5 0.0 2.4 2173 260.9 -6.2 2006-10-21 18:34:29 ISS 142.2 67.7 -1.8 366 261.7 -7.2 2006-10-21 18:39:26 ISS 57.1 0.0 ecl 2169 262.5 -8.1 2006-10-21 20:05:07 ISS 271.0 0.0 2.1 2174 276.9 -24.0 2006-10-21 20:09:46 ISS 340.3 19.3 ecl 874 277.7 -24.9 2006-10-21 20:14:25 ISS 50.2 0.0 ecl 2167 278.6 -25.7 2006-10-21 21:41:21 ISS 300.4 0.0 ecl 2175 296.4 -41.1 2006-10-21 21:45:39 ISS 0.6 11.7 ecl 1180 297.4 -41.9 2006-10-21 21:49:55 ISS 60.6 0.0 ecl 2162 298.4 -42.6 2006-10-21 23:16:50 ISS 309.8 0.0 ecl 2167 325.4 -54.7 2006-10-21 23:21:30 ISS 20.3 20.3 ecl 838 327.2 -55.2 2006-10-21 23:26:09 ISS 91.0 0.0 ecl 2157 329.0 -55.6 2006-10-22 00:51:50 ISS 302.0 0.0 ecl 2162 8.0 -58.9 2006-10-22 00:56:45 ISS 218.2 57.8 ecl 392 10.3 -58.8 2006-10-22 01:01:38 ISS 134.2 0.0 ecl 2147 12.6 -58.6 2006-10-22 02:27:57 ISS 274.5 0.0 ecl 2157 46.9 -50.5 2006-10-22 02:31:10 ISS 233.3 4.7 ecl 1647 47.9 -50.1 2006-10-22 02:34:23 ISS 191.8 0.0 ecl 2146 48.9 -49.6 2006-10-22 17:17:08 ISS 202.9 0.0 2.6 2176 248.6 6.6 2006-10-22 17:21:45 ISS 134.7 19.5 0.3 873 249.4 5.8 2006-10-22 17:26:22 ISS 66.6 0.0 2.0 2178 250.2 5.0 2006-10-22 18:51:43 ISS 250.3 0.0 2.3 2176 264.3 -10.6 2006-10-22 18:56:38 ISS 331.1 39.4 -1.1 518 265.1 -11.5 2006-10-22 19:01:32 ISS 51.9 0.0 ecl 2168 265.9 -12.4 2006-10-22 20:27:51 ISS 287.5 0.0 2.0 2178 280.7 -28.4 2006-10-22 20:32:16 ISS 350.2 13.4 ecl 1102 281.6 -29.2 2006-10-22 20:36:39 ISS 52.7 0.0 ecl 2166 282.4 -30.0 2006-10-22 22:03:48 ISS 307.5 0.0 ecl 2174 301.7 -45.1 2006-10-22 22:08:13 ISS 10.4 13.5 ecl 1091 302.9 -45.8 2006-10-22 22:12:36 ISS 73.2 0.0 ecl 2161 304.1 -46.5 2006-10-22 23:38:55 ISS 307.8 0.0 ecl 2169 334.1 -57.1 2006-10-22 23:43:50 ISS 29.9 41.4 ecl 493 336.2 -57.5 2006-10-22 23:48:41 ISS 110.9 0.0 ecl 2148 338.4 -57.8 2006-10-23 01:14:09 ISS 292.5 0.0 ecl 2161 18.6 -58.3 2006-10-23 01:18:40 ISS 226.1 17.8 ecl 910 20.6 -58.0 2006-10-23 01:23:10 ISS 159.1 0.0 ecl 2144 22.6 -57.7 Thanks Erik Jacobsen, KB9BNY Varsity Scout Team Couch

HITSAT copied in EL88pg
by Andrew Glasbrenner 29 Sep '06

29 Sep '06

Congratulations to the HITSAT team! I copied the CW beacon from 22:42 at ~437.280, 22:44 at 274.3 (just after time of closest approach), and 22:45:45 at 268.2. I was busy pointing and tuning, so didn't get any of the telemetry, and Mixw didn't either. There is a bit of a gap between transmissions which makes tuning and pointing by hand a bit tough, especially with no keps ;-) The signal was quite strong at times, up to s9 or so on a M2 30cp and Landwehr preamp. Looking forward to 1200 baud data from this satellite hopefully. 73, Drew KO4MA EL88pg New Port Richey, FL AMSAT LM 2332

OSCAR-11 Report
by Clive Wallis 29 Sep '06

29 Sep '06

OSCAR-11 REPORT 28 September 2006 NOTHING HEARD FROM OSCAR-11 DURING SEPTEMBER ... REPORTS REQUESTED! Please post reports to AMSAT-BB or e-mail to xxxxx(a)amsat.org (replace xxxxx by g3cwv). During the period 14 August 2006 to 28 September, the satellite was heard from 16 to 26 August. The beacon was expected to switch ON ten days or 20 later, ie. around 05 or 15 September. However, it has not been heard since 26 August. During the last ON period, the real time clock showed various errors. The date on 16 August was 51 July. By 26 August it had incremented to 60 July. The hours were also showing an erratic behaviour. Over short periods of time, ie. during a pass, the minutes and seconds appeared to be incrementing correctly I am indebted to Jeff KB2M, Peter ZL3TC and Dave G1OCN, for their reports and for monitoring the satellite, especially during the last two weeks while I have been away on holiday. Many thanks. The status of the satellite, when last heard, was that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 were still working. The spacecraft computer and active attitude control system have switched OFF, ie. the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed. When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus. After 22 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude. The watchdog timer now operates on a 20 day cycle. During the three months before May (when the eclipses started), the ON/OFF times were very consistent, and the average of many observations show this to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website. 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. The URL is www.users.zetnet.co.uk/clivew/ If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT125.CWV, to prevent duplication. 73 Clive G3CWV xxxxx(a)amsat.org (please replace xxxxx by g3cwv)

Sinclair Radio Labs A-2C08D
by G. Beat 28 Sep '06

28 Sep '06

This orphan RF pre-amplifier (Model A-2C08D) landed on my door step. It is a VHF (132 - 174 MHz) pre-amplifier that Sinclair Radio Labs (Tonawanda, NY) marketed in the 1970s. Its a Manhattan style construction in a nice Pomona box :-) Of course, this orphan does not work. Chance that anyone may have a schematic? ... likely a 4-pin FET ... before I open it up on the workbench next week? Initial e-mail to current Sinclair went un-answered. Phone call likely next, but I doubt they have the schematic for this old pre-amp on-file. Greg w9gb

I will be shipping in a few days ten antennas designed for portable LEO satellite work to Burghardt Ameteur Center. They are a LPDA simular to the Elk but with the eliments angled at thirty degrees to help the gain by about 3db. They are a true Dual bander VHF/UHF with single feed. They have been an on going project. Lou Mc Faddin W5DID has been my Elmer for them. Amsat may carry them in there store in the future. I have sold about ten of them locally and on Ebay to get feedback and have not yet received any negative comments on there perfomance. Her is a link for a better discription and pictures of one I sold on Ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=ADME:L:EOISSAA:US:… Fred KF0AK

YES !! RS-15 is alive !
by lu7abf 28 Sep '06

28 Sep '06

Hello Domenico, et all aboard BB Thanks for test and try. Perhaps there is some timer or condition that place/unplace operational the RS-15 transponder, or variable attitude hence antenna position. What I noticed, is that on-off period of beacon is variable, sometimes the cycle is about 1 second on, 7 sec off, under that situation I was not receiving the transponder. The time where I succeed getting back my uplink was when beacon was 10 seconds on and 2 seconds off. Perhaps it varies according to pannels solar exposure. When transponder operating, my CW replicates the same woeing that the beacon has, it means has some fming. Also it is possible that command station still has control over RS-15, and can set on or off transponder, or some external event is doing alike effect. That's reason I copied to control station email stated on RS-15 page. So, I will keep trying and perhaps we could infere some pattern about transponder operation. 73, lu7abf, Pedro lu7abf(a)amsat.org.ar www.amsat.org.ar

Hitsat auto doppler tuning
by Bruce Robertson 28 Sep '06

28 Sep '06

Gang: I thought I'd point out that the keps listed as 'TLE used at ground station in HIT(Hokkaido Institute of Teachnology)' on the page http://www.hit.ac.jp/%7Esatori/hitsat/hit-sat_tle.txt worked perfectly for me last night. Using the specified frequency of 437.275MHz I could hear the bird from rise to setting using doppler tuning software and not a jot of manual tweaking. Computer-aided tuning is particulary useful on Hitsat due to the long delay between telemetry lines. Enjoy! 73, VE9QRP Bruce

YES !! RS-15 is alive ! Reading a recent report on AMSAT-BB from Gary deMunbrun WA4RKS about RS-15, move me to try. Tks Gary! I tried on several passes, I always heard the intermitent carrier at 29.352, but no repeat of my uplink, trying either on official 145.858-98 or on suggested 145.958-98. All of tries were made with RS-15 on her night. But today I gave her another try. This time RS-15 was sunlight on a pass that lasted 20 minutes on Sept-28 00:24 to 00:43 LU Time. I could uplink first CW and after SSB and hear it back !!!!, despicte the fact that I'm only using 25 W from FT-736 on 2mts and a 2m turnstile !! Frequencies I operate where: Uplink 145.875 , downlink 29.374 with good signal return about s3. Unfortunately no one to try a QSO. RS-15 is amazing, with 2000 Km height, passes can last up to half an hour ! even earth coverage is quite broad ! So, looks that we have had a new child reborn, coming back to life from over ten years ago. You can find on http://www.amsat.org.ar RS-15 passes precalculated for your location and on your time, for a quick RS-15 . 73, Pedro LU7ABF lu7abf(a)amsat.org.ar

70cm preamp
by Alan P. Biddle 28 Sep '06

28 Sep '06

Bill, Something is very wrong. Setting aside the inaccuracy of S-meters, there should be negligible loss. I would expect something like that if the 2 meter output were used by mistake, since they are rated at about a 60 db isolation. However, your description seems to preclude that. "I also reversed it with the same results." Does this mean you swapped direction, or tried the 2 meter lead? What did you see for an SWR when you transmitted on 70 cm with the duplexer(s) in place? If you really have that high a loss, it will show up. Did you try and receive the satellite, or a local repeater, with the duplexer? Perhaps someone else will have an idea. Alan WA4SCA

Fw: 23 cm Loop feed
by kc6uqh 28 Sep '06

28 Sep '06

Here is a modification to a standard conifer type 2.4 GHz grill antenna. The loop gives it a feed for L Band used here to receive ATV 1.253 GHz while transmitting on 2.441 GHz. Filters are required on both bands to reduce white noise from the Xmit PA and leep power out of the receive preamp. Those interested in Pictures request via E-Mail and I will forward them. Art, KC6UQH Subject: 23 cm Loop feed Dave, Ted and Gary, Here are some pictures. #1, & #2 show the feed mounted on the dish from both sides, #3 shows the Split Feed balun. Clamp tight one end 12" length of # 12Ga house wire in shop vise, pull hard until straight, then strip off insulation with a box cutter. The loop is 2.64 " square center to center, formed from the # 12 hard drawn house wire with the insulation removed. Using a 3" length of 1/8 " copper hobbie tubing, cut two .025" wide slots one on each side for 2.4 " long. Trim back the braid 2.9 " on a piece of R/G 142, Strip 0.2" of the center dielectric from the end of the cable. Slide the copper tube on to the coax unsplit end first, fan out the braid, and bend over the center conductor and solder to one of the split ends, Each side of the loop connects to a split end of the tubbing. Silde a piece of 1/4" heat shrink tubbing over the copper tubbing and solder the braid to the unsplit end You can also solder a bracket to this end to support the cable, and in the center of the opposite side use a piece of acrylic plastic 1/16 thick, heated and bent to support the other side of the loop. After connecting the loop, shrink the tubbing and coat the matching section and connections with liquid electrical tape or yellow weatherstrip adhesive. Cable is then wire tied to the boom. The loop is 2.75 " from the center of the reflector where it is screwed to the 2.4 GHz antenna cover. This is a living document and comments about omissions, changes etc are welcome in the intrerest of maintaining an accurate documentation. Art, KC6UQH

L Band Uplink Ant
by Wayne Estes 28 Sep '06

28 Sep '06

Les W4SCO What do most folks use for a L Band uplink antenna? Wayne W9AE replies: The Teksharp 4-foot mesh dish kit was popular in the final months of AO-40 operation. Most people used it with a dual band patch feed, so one dish is used for L-band uplink AND S-band downlink. The TranSystem AIDC downconverter from K5GNA worked well in this setup because it doesn't require extra filtering to reject strong L-band TX signals. The 4-foot mesh dish has less wind load than a solid 3-foot dish and more gain than the biggest yagi or loop antenna. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik

Wayne replies: I built my Teksharp 4-foot dish kit with 1/4 inch hardware cloth which is 80-90% holes. Other people estimated that it has about half the windload of a solid dish in a very high wind, which would be slightly less than the wind load of a 3-foot dish. Anecdotally, people have reported that it's still extremely windy when they stand downwind of the dish in a gale force wind.

The Teksharp dish isn't intended for higher microwave frequencies because of the 8-petal design isn't a precise parabola. And of course at higher frequencies you would need a finer mesh than 1/4 inch hardware cloth. I wonder if the 4-foot Teksharp 8-petal dish can match the gain of a perfectly shaped 2-foot dish at 5 or 10 GHz? That would still be a lot of gain. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik

HITSAT heard in CW mode over West Malaysia
by Sion Chow Q. C. (9W2QC) 27 Sep '06

27 Sep '06

Hello All, Today, 27th September 2006 at 1048 Hours UTC, I had a 27 degree pass of HITSAT over West Malaysia. I am very happy to announce that I heard its CW signal on 437.275 MHz +/- as soon as the satellite was about 0.3 degrees in elevation. This is also the first time I am hearing a signal from this satellite. I have recorded the entire pass and those who are interested may download the MP3 recording at http://www.9w2qc.net/hitsat/hitsat.mp3. The size of this file is about 5.2 MB and is about 11 minutes in duration. I was using Object-B keps (29480) as announced by Mineo-San (JE9PEL) earlier. Equipments used were ICOM IC-910H and 2 x Diamond A430S15 (15 Element) UHF Yagi, Vertically Polarized. Unfortunately, my preamp has failed to work, so no preamp was used to copy this signal. 73, Sion Chow Q. C., 9W2QC. -- No virus found in this outgoing message. Checked by AVG Free Edition.

Re: Why do the amsats get more and more complex?
by Rick Hambly (W2GPS) 25 Sep '06

25 Sep '06

Jason, I can easily imagine how you may have come to the conclusion by listening to some people on amsat-bb that satellites are becoming bigger, more complex and more expensive while not providing you with better services. You might even think that AMSAT officials are not listening. Nothing could be further from the truth. P3E is designed to provide services similar to AO-13 in an effort to make it smaller, cheaper and simpler than AO-40. It also will carry experiments essential to the future P5A mission to Mars. This is a very reasonable increase in complexity for a good purpose. Eagle is intended to be a series of satellites. Eagle has been designed to be smaller, lighter and cheaper than AO-40. Its shape was designed to optimize a low inclination orbit like the one AO-40 attained. This unintended orbit turned out to be very attractive to many users and it provides for orbit stability and much less propulsion, further reducing mission risk. It also carries fewer payloads and these payloads have been specifically chosen to get the best performance for the maximum number of users. Both P3E and Eagle have chosen Software Defined Transponders (SDXs) to implement the "linear transponder" functions for many reasons. Among these are efficiency, stability, linearity, cost, in-flight performance improvement, the ability to simultaneously share the transponder with other modes (Packet, APRS, SMS are possible examples), and the ability to change performance parameters in flight. This choice does not make the satellite bigger, more expensive, or less useful, etc. In fact, it is just the opposite. Eagle will carry a payload that it is hoped will revolutionize Amateur Satellite communications and Ham Radio as a whole. Initially called C-C Rider, I will call it the Advanced Communications Package (ACP) because it no longer uses C-band for both uplink and downlink. This package will be designed to bring satellites and DX to you and to many other Hams who have never been able to use a satellite or operate DX before. This is because the ground station antenna will be small, power levels reasonable, many modes will be supported (from Voice and CW to Video and data communications), the ground station will be affordable and the signal quality will be superior. Much of this is accomplished through the use of digital techniques so it will require all new equipment on the ground. AMSAT will design the ground station equipment and publish everything so you can buy it, copy it, sell it, or build it. The Eagle band plan has been the subject of much discussion, of late. Eagle is still in the design phase and the band plan is not finalized, so don't worry just yet. The confusion was the result of the ACP (C-C Rider) team realizing that they had to find another band for the uplink. They chose S-band for some good reasons but that recommendation is under review by the whole Eagle team and is not yet final. There should be a final announcement at the AMSAT Symposium in a few weeks. I encourage everyone to come to the Symposium and meet your AMSAT officials and learn what is really happening in AMSAT. There is much more I could say but, in summary, the new satellites are getting better in every way compared to the old ones. The future is bright and we need your support and involvement to achieve these goals. Rick W2GPS AMSAT President Subject: [amsat-bb] Why do the amsats get more and more complex? From: Jason White <jason@xxxxxxxxxxxxxxxx> Date: Tue, 19 Sep 2006 10:48:44 -0400 ---------------------------------------------------------- This is intended to be an honest question that I've wanted to ask, but I don't want to spark controversy or long threads that monopolize the reflector. I have a feeling this could go either way, so I'm just asking politely that the thread not go that way! It's not my intent. Anyway, I'm just curious why it seems that every new satellite project proposed seems to be bigger and more complex than the last? I keep hearing about exotic modes and uplink/downlink bands for P3E. Software defined transceivers, etc. etc. and what it looks like to me are more and more failure points. I understand the need to push the limits of technology as a justification for our very existence, but personally I feel like the designs are overly complicated and highly priced. I'm not ready to switch my earth station to SDRs, for instance.. I'm dubious about putting one into orbit.. then again, I'm not skilled enough to make those sorts of decisions. What I'm getting at is that Oscar 7 proved how reliable older technology can be.. For the price of one of the phase 3 birds it seems like several Mode B linear transponder sats could be put up, or a few more FM sats. I personally would much rather see a modest mode B sat in AO-40s intended orbital pattern than to try to wrangle parts for microwave. Did it get too easy for people or something? Wouldn't it be better to separate out some of the more experimental stuff from the old standbys? That way a failure of one whole sat would still leave something usable for the same money spent. My vote would be to piggyback a completely independent analog satellite onto P3E "just in case". Like I said, please, I'm looking for a real, thought out response. I didn't write the above to be a critique or to troll or anything like that, I am just curious because it seems to me, as an outside observer, that after the failure of AO-40 the direction was to go bigger and even more complicated, which left me cold considering what I had done at my station to work AO-40. Even when AO-40 was up I felt it was very odd that time and money were spent on components and systems that were never used (did the solar panels ever deploy?) Yes, I know the sat was damaged, and that explains a good bit of it, but it still felt like some things were wasted. Emphasis on "felt".. I couldn't know the real process that resulted in the decisions made. If someone could help me understand why the direction is the way it is maybe I could get excited about the bigger sats, but I think you get more "bang for the buck" with the smaller less complicated birds. My favorite so far is PCSat I. Mostly off the shelf hardware and I had a very easy time digipeating APRS through it. One of those in an elliptical orbit would be a hoot! 73s, Jason - N1XBP P.S. - One last plea, this isn't a troll! I'm worried people will think it is. _______________________________________________ Sent via AMSAT-BB(a)amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

AO-51 38k4
by Viktor Kudielka 25 Sep '06

25 Sep '06

Today, Monday, I followed three passes of AO-51. Downlink seems to be perfect with antenna mounted pre-amp activated and LHC polarisation: Four to five times "PB: Empty." followed by "Open ABCD: B: 96373368" No sign of any successful uplink. I tried directory requests with different output levels and different circular polarisations on 145.86 MHz, to no avail. Anybody else successful ? Vy 73, Viktor, OE1VKW

Re: Galileo interference on L band
by Tom Clark, K3IO 25 Sep '06

25 Sep '06

Sorry -- I've been away from home on business while the latest flack occurred under the general topic heading "Galileo interference on L band". First off, just so everyone can read the presentation materials that we used during the San Diego meeting, please take a look at the EaglePedia web site at http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/San_Diego_Digital…. Then take a look at my presentation "Frequency Considerations for Eagle" at http://www.amsat.org/amsat-new/eagle/EaglePedia/uploads/1/19/Microwave_Freq…. You will see (my slide 6) that I present the arguments pro/con about why (IMHO) L-band is at jeopardy as a long-term uplink band. Let me add a few comments about why I'm so concerned. The reason that the Galileo E6 (functionally the same as GPS L2, and overlaying the amateur 1260-70 MHz uplink allocation) is important for some uses is that it, when used in combination with the primary 1.57± GHz "L1" frequency (which is what all your cheap hand-held GPS receivers use), can be used to correct the ionospheric errors; the ionosphere adds upwards of 10 meters to the pseudo-range for each GPS satellite. Because of geometric factors (expressed quantitatively in VDOP), this can in turn yield errors in height of up to about 30 meters. [The WAAS and EGNOS signals provide some correction for these biases to the few meter level, but cannot be relied on during severe ionospheric storms.] There is a lot of factual evidence that when dual-frequency geodetic GPS receivers (costing ~$25,000 -- hardly cheap!) have been used in proximity to terrestrial amateur L-band stations, the GPS performance is seriously degraded. I direct your attention to several reports on the topic: * Must reading -- GPS/GLONASS vs L-band digipeaters (Also see GPS World, Oct.2002) (warning contains numbers and equations, as well as uncomplimentary comments about digipeaters) http://elib.uni-stuttgart.de/opus/volltexte/1999/278/pdf/278.pdf#search=%22… * Amateur and Radar QRM reported at a 1999 technical meeting: http://www.navcen.uscg.gov/cgsic/meetings/summaryrpts/33rdmeeting/Presentat… * A tutorial that shows how interfering signals can affect a spread spectrum GPS rcvr (caution -- contains more numbers): http://www.rin.org.uk/SITE/UPLOAD/DOCUMENT/Vuln-Owen.pdf#search=%22gps%20am… Even though US amateurs may feel that Galileo is a "European only" problem, read carefully Rick's (W2GPS) comments -- in his real life for many years he was a VP with ARINC (the people who worry about standards in the airline industry) and was on many FAA and ICAO committees that decide on airline safety. Also realize that the Europeans are absolutely determined to develop their own GNSS (Global Navigation Satellite System) call Galileo -- in part because they don't really trust a system that depends on the US Military, and in part because they see a giga-Euro business opportunity for the EC. Who knows how long it will survive, but the Russians have their competing GLONASS system. And both the Chinese and Japanese see that they need to enter into the GNSS race is they are to be world-class technical competitors. We, the Eagle technical team, have never said that L-band won't work NOW or 5 years from now. But our vision for Eagle is that when the first one flies 4-5 years from now, we want it to be a useful resource for at least a 10 year lifetime. We are very concerned about making a several million dollar (after you count the volunteer builder's blood, sweat & tears) investment only to have it blown away right after launch by the GNSS cartels just because we picked L-band to be anything like a "primary" uplink. 73, Tom

Fuel on the emergency communications(satellite)fire

25 Sep '06

It is quite apparent that some on here have never been on either end of a need for communications, either in the form of a drill for training, or more importantly on the receiving end in an ACTUAL emergency... Some of us have been on both ends. And, PARTCULARLY, when you need an assist, ANY method of communications, no matter how brief, may be the one you need... Jungle drums, smoke signals, a five minute satellite pass, cell phone, indian code talkers, I'll take anything I can get!! 73, Dave wb6llo(a)amsat.org Disagree: I learn....

Hi, It looks like I will not be able to attend the Symposium this year (unless a ride to the Symposium magically appears). In previous years there was (sometimes) a plan to record the presentations and then make the recordings available to those who could not attend. Is there a plan this year to make recordings?

Looking at the Eagle page I see proposed U,L and C band recievers, and V and C transmitters ( I assume from all the noise that S tx is not going to be used) What will the pairs be, U/V, C/C, and L/? ? Has that been proposed yet? Bill KB2RC, AMSAT 6986

I enabled SO-50 at about 0215 on 24 Sep 2006. I tried to raise a contact but only heard one other station. Couldn't make him out because the elevation was getting too low for my Arrow antenna and it is hard to optimize the signal that is only there when someone keys up on the input. You would think there would be more activity on a weekend. Hope to hear more of you on SO-50. 73, Dave W8IJ
