HITSAT reception
by Andythomas 23 Sep '06

23 Sep '06

Just to confirm my reception earlier this eveing of a fragment of trlrmrtry. I have a very basic setup here - this should inspire people to listen out for these cubesats. I have only a AOR8000 hand/held scanner for cw at 70cm and I built my own 70cm RHCP 6 ele yagi (no preamp). I predicted the az and el of the pass using object A keps and at 17:38:25 utc on 437.8125 CW (and dopplering down) recorded a .wav file to transcribe later as: 0d4d4f (maybe "g") 46f 84c This compares well with more competent reports (DK3WN)!! The cw decode from the Hitsat website gives me: Element set decode received EE temp. w face 0d DD temp w face 4d GG temp x face 4f HH temp x face II temp y face JJ temp y face KK TX temp LL battery temp 4c Don't know what units these elements are in though. So there we are, modest equipment, can read the housekeeping data from Hitsat! I've sent a WAV file to the command team, if they can make sense of it. andy g0sfj

RS-15 satellite.
by Garyatlnt＠aol.com 23 Sep '06

23 Sep '06

I was reading recently about the status of RS-15 which was declared semi-operational. Nevertheless I thought I would give it a try. I would sporadically hear the beacon and then try to access the transponder and remained persistant in trying for several days, then about 3 days ago I turned on my rig to try and forgot the uplink frequency and wrongly entered 144.958 to 144.998 [rather than the listed uplink of 144.858 to 144.898] and the transponder responded with the downlink still in the listed range of 29.354-29.394. I have continued to be able to get the transponder to respond by useing the "wrong" uplink of 144.958-144.998. I hope others will try the same as I sure would like to make some contacts rather than simply hearing my own signal. Thanks. Gary DeMunbrun [ WA4RKS].

CW decoder for Linux? [was HITSAT CW]
by John Mock KD6PAG 23 Sep '06

23 Sep '06

Anyone know of a good adaptive CW decoder for a Linux? The one i'm familiar is fairly old and operates at a fixed speed, which isn't so good if one wants to set things up to receive several satellites and especially if one doesn't know the CW rate in advance. I hacked something like this into one of the PSK31 programs (intended for hand-sent CW), but the original source has changed substantially since then and is graphically oriented (which isn't very useful for telemetry). -- KD6PAG (Networking Old-Timer, Satellite QRPer) [Note: If i'm in your address book, please replace 'qsl.net' with 'amsat.org'.]

Object A Best Fit For HITSAT

Now that a little time has passed since launch and there is some separation between Space-Track.org Object A and D, it appeared this morning that Object A Keps are better fit to my AOS and LOS for HITSAT.

I to 'copied' HITSAT from here in West Central Florida. AOS at 22:43 on 437.275 (because that is where the receiver was set to) with a solid S9 signal. Copy Following Data Signal 599 at 437.275 AOS at 22:43 2c4f504d514c4a4b c1d1d2e6 JR8YJT 29011317222D LOS at 18:47 437.266 MHz Agree with Drew, the long gaps in transmission made for tuning and copying a bit hard. Hence, the there are gaps in the receive data while looking for the signal to reappear. Good Luck HITSAT. Looks like you got a SAT that's a HIT... 73 Keith N4ZQ EL88pa

Here's a couple of snippets from this evenings AMSAT-BB digest. Looks like these wireless cameras are going to cause problems to the Galileo E5 service. Especially as a 200mW version is available on ebay for £15 (Yes, they do actually generate that level of RF power!), there are going to be a lot of them about! Jules snip ------------------------------------------------- Wireless 1.2 GHz cameras I just picked up one of these little $60 cameras and am glad to report that they are not in the Amateur Allocation. They are 40 MHz wide each (4 channels) starting at 1060-1100, 1100-1140, 1140-1180, 1180-1220. But I was impressed with their range. An easy 1000' with the supplied receiver. My guess is about 5 milliwatts ERP. The energy at the edges was more than 60 dB down... ------------------------------------------------- snip ------------------------------------------------- Current publicly available Galileo documentation indicates that "Safety of Life" services will be provided on E5a/E5b (1164 to 1215 MHz) downlink and the E2/L1/E1 (1559 to 1591 MHz) downlink. The E6 (1260 to 1300 MHz) downlink is designated for 'commercial services' and not the aviation. Thus, I am VERY curious why the interference to aircraft navigation receivers is constantly brought up in this discussion as it appears a non-player. -------------------------------------------------

"PR" of PcSat2 during spacewalks this week
by Nate Duehr 21 Sep '06

21 Sep '06

Bob will probably have some comment on this, but I wondered if anyone else noticed it. I've been listening to/watching NASA TV most of the week with the Shuttle mission going on, and was obviously interested to watch/listen during the spacewalks. What I found especially interesting (or disturbing?) during the spacewalks was the announcers descriptions of the external payload boxes being worked on, like PCSat2. When they worked on removing PCSat2 there was this (almost mumbled) dumb description of what is was -- something like "radio experimentation equipment". And that's about it. No mention of its name. No mention that it was built by students at the Naval Academy. No mention of Amateur Radio. Yet, the next day when they were removing the other science experiments, there were long gushing words about all the peace, love, and worldwide joy that a box with 20 different pieces of metal stuck to the outside would bring as the scientists of the world, as they would be able to see the effects of being outside in space had on different metalurgical alloys. Sorry - ok yes, I'm exaggerating. But my curiosity is still piqued. Why was PCSat2 given such a "boring" billing during the announcer's time to speak about what the Astronauts were doing, versus all the glowing/gushing descriptions of the other scientific experiments? Is radio science or the word "Amateur" in Amateur Radio a source of some kind of embarasment for NASA PR people these days? Or, was there simply no good typed up description for the announcers to read from, so they skipped it? (I'm hoping here...) In other words, was there a PR opportunity for Amateur Radio missed because no one had time to send a good description and make sure it got into the correct hands for reading during the spacewalks? Was there anything anyone could have done to make the description of PCSat2 at least sound more interesting than a mumbled comment about a radio black-box the announcer seemed clueless about? Or at least even have its NAME mentioned so people with a web browser and Google could find the rest of the story? Somehow I want to give the announcers more credit than that they were just "dumb" about it -- they all seem to be VERY well versed in what's going on in almost all aspects of Shuttle operations. Along those lines, is there any reason they would be told NOT to say what it was, perhaps? (Hey, it's a possibility, right? I'm not much of a conspiracy theorist, but you have to consider all possibilities.) I'm very curious. Probably more than I should be. :-) Anyone else notice this? Nate WY0X

I don't know what the situation is where you are, but in Europe 23cms is not 'Our band'. it is allocated for aeronautical navigation. We are, and have always been, secondary users. So any confrontation with the primary users would be counterproductive. Recently there was an incident where an ATC radar had developed a fault, which the authorities were unaware. UK amateurs characterised the fault and DF'ed it to a particular installation. This has undoubtedly earned us brownie points. We have been coexisting with CAA radar for many years, I'm sure we will continue to do so when Galileo comes on line. The L band signals are for the commercial service of Galileo. There are currently no fixed plans as to what this form this service will take and who the customers would be. But, I would have thought that any aviation system would use the public service, probably in conjunction with existing GPS. Even if our signals do block the commercial services, I am sure that the receivers employed will default to taking location data from the public Galileo and GPS service. So I would doubt that the users would even be aware that there is an issue. Fingers crossed.

Re: Galileo / US GPS
by joseph Murray 20 Sep '06

Hi Bob You said" What will happen if the Galileo goes up is that no European airport will allow a commercial jetliner to land without the Galileo system. This will inevitably lead to this basic system being in world wide use for navigational purposes ------- Does this imply that all airliners going to and from EU and US will have to have both Global positioning system ? ( Galileo and the US GPS) It would appear that the country to which an aircraft is approaching could demand a specific space navigetion syetem to be used. As I understand the current Galileo event : It is in test phase. No actual system funding has been established. No list of users have been verified to be real supporters. The use of the US GPS system does not cost the EU anything. All EU users of the current US GPS system will need both if there is no global support for a single system Without a Amateur satellite using a mode L up link that uses narrow analog and/or wide band digital modulation ( which could change over time ) the Galileo testing is not really testing for amateur interference.

The SSETI ESEO GTO project
by Graham Shirville 20 Sep '06

20 Sep '06

Hi All, Just a quick update about the SSETI GTO satellite project. It is still on track for a launch from Kourou in Nov 2008. The planned AMSAT-UK U/S linear transponder is still on the manifest. (We do not have any opportunity to change from this frequency selection) The transponder is expected to have: an approx 50kHz bandwidth 10 watts of RF output Selectable DSP/SDX and analogue signal paths a 400bps beacon linear antennas with not much more than zero gain The satellite may not have good, long term, attitude control therefore: the antennas are being designed to work well even if the satellite is tumbling the link budget is not as good as AO40 was nor as P3E will be:( circular polarisation of ground segment antennas will be needed. Before we operate the system as an amateur transponder, it will be used as the initial main communications package for the reception of telecommands to, and for the transmission of telemetry and mission data from, the satellite - so it is quite important for the whole project:) The Preliminary Design Review will be completed during next month and an engineering model of the satellite should be under construction early next year. Hopefully this process will be visible using the same webcam system as we were able to engineer during the SSETI Express construction. The website http://www.sseti.net/ has lots of info about the SSETI program(me). Click on "missions" and ESEO for more details about their plans for their GTO satellite. A full report on the SSETI Express launch last year, the SSETI ESEO project with the DSP transponder, and their SSETI ESMO (moon orbiter!) project will be provided at the upcoming AMSAT-NA Symposium. 73 Graham G3VZV

Re: Why do the amsats get more and more complex?

We lost 1215-1240 MHz to GPS and were required to accept interference from ISM devices on 2400-2450 MHz 25 years ago so further restrictions are possible in the future. 73, John KD6OZH ----- Original Message ----- From: <sco(a)sco-inc.com> To: <amsat-bb(a)amsat.org> Sent: Wednesday, September 20, 2006 18:30 UTC Subject: [amsat-bb] Re: Why do the amsats get more and more complex? Looks to me that only the commercial service will possibly interfere with the Ham L band uplink. The open service signals will not be in the L band. Even then the Commercial service will be broadcast in three bands, only one of those is in our ham band. I would therefore assume if the commercial receiver was having interference on the CS channel (our L band) that it would switch over to one of the other TWO Open channels to gets its info. See the specs below. So what is the problem. Are we afraid that we might offend the Europeans if we are on one of their three channels? Sounds to me like Europe is building this system so they will have their own GPS if they decide to go to war with us.

Mode B equipment for eagle (fwd)
by McGrane 20 Sep '06

20 Sep '06

Greetings- considering the recent discussion regarding Eagle modes, I thought I would repost this question for any answers. Will I be able to use traditional SSB gear for Eagle mode B? I have recently combined an Azimuth rotator and a cheap TV rotator for elevation adjustments using short beams but can upgrade the antennas later. Thanks in advance for any replies, pat n2oeq ---------- Forwarded message ---------- Date: Sat, 9 Sep 2006 07:46:45 -0400 (EDT) From: McGrane <tmcgrane(a)suffolk.lib.ny.us> To: Amsat BB <amsat-bb(a)amsat.org> Subject: Mode B equipment for eagle Greetings In the past couple of years, I have set up a very cheap satellite station for mode B. I had a 2 meter all-mode mobile rig (FT480R) I paid 50 dollars for connected to a cushcraft 4 element Yagi beam. I purchased a 70 centimeter FT790RII for $125 and made a homebrew 8 element Yagi. Antennas are monted on single azimuth rotator mast and angled up about 10 degrees. This setup works extremely well for hamsat (VO-52). Now, going from LEO hamsat to HEO Eagle, I will probably have to make a longer UHF yagi and add an amplifier, Also a longer VHF beam. I already have a mirage 2 meter amp with built in preamp. If the coax is short as it is now, I can use the amp's preamp. I saw a reference in one of the flurry of emails mentioning a 1KW ERP SSB station for eagle. Right now, for UHF, I'm at about 250 watts ERP. Either adding an amp or making a new antenna will bring me up to 1KW ERP or more. Am I on the right path? Will I be able to add to this equipment to work Eagle or will something totally new be required for mode B ? Thanks for ideas, Patrick N2OEQ

Problem with Wisp (View-Dir)
by N6FO - Jim Cottle 20 Sep '06

20 Sep '06

Hi there, I hope that this newbie issue is not too annoying. I have read the AMSAT digital guide, reinstalled WiSP on my Windows XP computer in the C:\ root directory and have successfully read and requested files from GO-32 (with success). Both GSC and MSPE seem to work as they should. Try as I might however, when I use the program View-Dir, I see NOTHING!. I know the files are there, because I can read them individually (like message files and the MSPE header file for the directory). They are also in their proper directory structures (for AO-51 and GO-32) Anyone out there have a clue as to why View-Dir in my installation cannot actually see the PHF (I think that is the extension) info in the directory file? Makes housekeeping impossible. Any clues or anyone else have this sort of issue that they eventually resolved? Thanks in advance. Feel free to email me directly, or respond here (as appropriate for others). I look forward to learning why View-Dir has such a peculiar issue on my installation. thanks again. 73 Jim N6FO Many thanks to Dave G1OCN for help in navigating some annoying difficulties....THANKS ELMO..;).

> Tried with a handheld with a whip, heard a couple calls but couldn't make > them out. Anyone have success with a like setup? I used to work AO-27 routinely with a long rubber duck, but i cheated a bit. Most often, i'd use a chain link fence (otherwise a large street lamp pole) as a reflector. I'd try to keep the radio about 1/4 of a 2 meter wavelenth from the fence (which 3/4 of a wavelength at 70cm). It made a big difference compared to operating in open space. One time, i worked both Alaska and Hawaii from the parking structure of the Walnut Creek BART station with a long rubber duck and metal fence as a reflector, and i think it was even on low power. This is not a beginner-type thing to do, but with a good path and a good radio, sometimes it can be made to work. Don't do this without a full duplex dual-bander or two radio, as otherwise you are very likely to cause QRM and make sure you can copy callsigns before transmitting!!! ID as QRP, as then folks may also help you out. 73's and good luck. -- KD6PAG (Networking Old-Timer, Satellite QRPer) P.S. SO-50 have been fairly quiet lately and more usage would be appreciated even on transcontinental passes. [Note: If i'm in your address book, please replace 'qsl.net' with 'amsat.org'.]

PO-28 SK

Thanks for the link, Pat. I have been asking for quite some time for an update, ANY update on this bird. Here is the post for those who may have missed it: AMSAT-UK -- POSAT Written by G3YJO Monday, 18 September 2006 Following the recent kind agreement of Consórcio SAT, the owners of PoSAT (PO28 or 1993-061D) which was launched on the Ariane V59 from Kourou on the 26th September 1993, work has been progressing at SSTL and the Surrey Space Centre to switch transponder frequencies to the amateur satellite service to serve as a voice FM transponder for use by all radio amateurs worldwide. Unfortunately, recent investigations now indicate that the PoSAT onboard NiCd batteries are showing the effects of 12 years in orbit and the approx 100,000 charge /discharge cycles to which they have subjected and are no longer holding sufficient charge to operate the downlinks. This may mean that, sadly after all, it will not be possible for the satellite to be made available for amateur use. We fully understand the benefits that PO28 would offer radio amateurs and work is continuing at Surrey to see if there is any way to revive this 'old lady'. Watch this space for further updates.

Re: Why do the amsats get more and more complex?

Thanks to everyone who replied, and to those who may still reply. I suppose what I needed was a subtle shift in point of view and several people provided clear and relevant information which allowed it... I also was under-informed.. time to update my copy of the Satellite Experimenter's Handbook :) What I was misinterpreting is the balance between "what we know works" and "new and experimental". I was under the impression that too much emphasis was being placed on the later, however with a bit of research spurred by the conversation it seems a bit more like ensuring operation by modest stations was a design characteristic of some of the newer sats. I'm still a little skeptical of the SDR transponder, and I probably fall under the category of those who feel that maybe there should be an analog backup, but if it will help with "Alligatoring" I'm all for it (speaking as a small low-budget station..hihi) There is a sort of paradigm shift when you stop thinking of a bird as a "repeater in the sky" and more as, for example, "a martian mission test bed (that also has some parts you get to play with)". I think there is room for both "bleeding edge" and "old stand-by" technology in the amateur satellites, but perhaps my own personal bias tends to lean a bit more conservative in terms of how much of each the final mix should be. As someone said, a model T may be reliable but would you want to drive one to work? Well, maybe not.. but I wouldn't want to commute in an F-16 either! There's a good middle ground somewhere. Thanks again for the good responses, they answered a lot of my questions. 73, Jason - N1XBP

This discussion seems to have lost track of some essential facts: 1. Both P3E and Eagle *ARE* smaller and simpler than AO-40. 2. Both P3E and Eagle plan to have a U/V (Mode B) transponder. 3. Eagle plans to have a backup analog transponder path in case the software-defined transponder fails. I'm not happy about the announcement that Eagle won't have a S-band downlink. But the next HEO satellite, P3E, will have a S-band downlink. The Eagle team might reconsider their decision *IF* the P3E S-band downlink proves to be useful and popular. After all, at this point Eagle is just an idea - no satellite has been built yet. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik Financial contributor to P3D, P3E, Eagle, and AO51 projects

AO-51 Fund Raising...24 hr update
by mike honer 19 Sep '06

19 Sep '06

WOW! Already ten responses, most of them positive, and three of them definitely not. FUND-RAISING 101: from my good wife Anne, who does this for a living...(Fundraising Counsel for non-profits) Success comes from asking: The Right person At the Right time In the Right way For the Right gift And in this situation: The Right person is one who hasn't yet considered joining or making a contribution The Right time is now, while (s)he is excited by the new possibilities The Right way is straightforward, friendly, non-threatening, and encourages participation. The Right gift, which for this kind of solicitation might vary from $10 to a full membership. The idea is to identify those folks and reach out to them. And I can't for the life of me think of how this could demean, threaten, or alienate anyone. And the Ham Spirit will not be trampled upon,spindled, folded, or mutilated. And one of the things that I have learned by osmosis is that It's OK to ask for the money (gift), especially if your case is well made. We will need 10 to 20 widely spaced listeners to record all the calls heard over 3 days, one or two passes per day, during V/U operation of the satellite. Weekends can be very crowded but yield lots of calls. Those lists of calls are forwarded to Martha, and she has agreed to run them against membership and identify those we should reach out to. Maybe we should have custom "AMSAT Outreach" QSLs made up as post cards for this effort. Maybe a contribution of $15 gets a complimentary copy of the Journal. I can't help thinking of the dozen or so newbies I have heard calling on '51 who never heard an answer. What a great way to let them know they are on the right track. Maybe this convinces some more of you that I am on the right track......? Mike, W1BFN

AO-51.....Fund-Raising Opportunity?
by mike honer 19 Sep '06

19 Sep '06

I called Martha with this idea today, and she suggested I put it on the b-b, so here it is: AO-51 has been a real "hoot" for a bunch of hams, including me. judging from their technique and their QSLs, many of these ops are doing the sats for the first time. And probably most of that group do not belong to Amsat. (And they should, you know) Since FM05 is not easy to find on '51, I've been getting more than a few QSL cards, and have started to ask the question on my return: "How about $ending Amsat a thank-you note?" Yes, $, not S. So, my idea is that we should try to get those whom we hear on '51 and who are not members to join Amsat, or at least send a few bucks in. Works either way for me. For those who would like to try this: Martha has said that she will run calls against the members list and tell us who is NOT a member, if we send her lists of all those we hear on '51. No need to try to talk to all these folks, it's crowded enough. For my part, I will supply the first 500 39 or 24 cent stamps to put on the the QSLs you would send to those identified as non-members. We should know how or if this will work by the response to the first 500 First goal would be to generate 100 new members or contributors. I am not a subscriber to the list, so please contact me at amhoner(a)rtmc.net with comments, criticisms, or offers to help. Thanks for the bandwidth. Mike Honer, W1BFN LM 2252

Greg - Many early satellite TVRO systems (cable head ends and early home users) - that used that used 10 foot BUD (Big Ugly Dish) used an IF of 70 MHz -- so reception of "S" band was fairly straight forward.

AO-51 mode L/S
by Michael Fletcher 18 Sep '06

18 Sep '06

Hi all, been copying AO-51 on L/S mode very nicely over the past few days. My setup is a hand-held linearly polarized (yes, you need rotate it to follow the S/C spin) W-LAN patch antenna with a California Microwave downconverter feeding an FRG-9600 modified to feed DC to the D/C. Excellent signals, absolutely no interference, always enjoying the spectacular L band uplinks for various European stations, especially OZ1MY, whom has an exceptionally solid uplink :-) Mostly been listening to eastern and overhead passes, simply because I can sit on my veranda steps, sip coffee and twiddle the knobs & antenna ;-) Really cannot wait for the next L/S session; this mode is a very impressive demo mode for experienced hams that have no idea what satellites can do for you, not to speak of our future generation of hams... 73's Michael, OH2AUE

Hi AMSATs, --Snip-- "If there is sufficient folks and money to support such an independent project, I would suggest hiring established transponder engineers to do the actual design and construction...i.e someone known and respected by the "Amsat family". Afterall, such a module must satisfy all the spacecraft requirements and testing to qualify to be included and flown." What are the specifications for this s-band transponder ? Like: Power supply, RF power output, physical size, input IF etc... I will have a look what is possible... 73 de PE1RAH William Leijenaar --- __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

AO-51 Mode L/S
by Reg Wood 18 Sep '06

18 Sep '06

I had one contact with VK2DAG only enough to swap callsigns but the signal my end was consistently 20db 0ver S9 and could get into the bird with about 6 watts from an IC-910. I am using my AO-40 dish which is a 1.8Metre mesh dish with a L/S patch feed and controlled by Uni_trac. On most passes that I tried I could hear my own signal coming down from AO-51 which was most of the time at S9 with a very slow and deep fade. I was please to be able to check how it was working after it had been unsed since AO-40 ceased operation. Thanks Echo schedule team for chance to blow the cobwebs out of the equipment and looking forward to the day when P3E and Eagle is up there.

AO-51 S Downlink
by Clare Fowler 18 Sep '06

18 Sep '06

In addition to pointing the antenna directly at the satellite and determining the offset of the downconverter frequency there is a third large variable in being able to receive mode S. I have received full quieting signals with a 6 1/2 turn helix when AO-51 is above approximately 35 degrees elevation. This evening I tried a QSO with Dave G1OCN when we both had a max elevation of 5 degrees. I could hear him and myself for over a 3 minute period but he did not hear himself or me. I was receiving with a 1.2 meter dish which has about 14 db +/- more gain than the 6 1/2 turn helix. With the dish the AO-51 downlink signal is +10 db over S9 when the elevation is above about 15 degrees. The AO-51 signal at 4 degrees elavation was S5 +/- QSB. This is again a difference of about 14 db. (S meter checked with a signal source and step attenuator) This 10 to 15 db loss in signal level at very low elevation can be partially attributed to increased range but primarily due to the off pointing angle of the S band antenna on AO-51 Farther measurements would likely show considerable variations in the S band downlink signal level relative to elevation and azimuth.

Hi to all I just reading back my archives and i found if you want to know where to you want to go you have to know where you came from. Here is a what we can read on March 25 2005 Greg Wycoff wrote: > ... > I hope others will share their thought and memory's of AO-40/AO-13/AO-10 > so we can help start the drive for raising money for EAGLE and get > others geared up for P3E. > ... I became QRV on the AO-40 late in its life, on Aug. 20th 2003. I started out in mode U/S with antennas made out of cardboard boxes and aluminum foil, the way Tony, AA2TX described them on p. 57 of QST March 2003, and with a DB6NT S-to-2m downconverter. The rig was an IC-910. I was able to operate very close out to the apogee, with the 50W UHF into the corner uplink antenna. The performance of the downlink S-band horn surprised me. I operated mostly from indoors, through an open window and thus could not make use of every pass, but after my first 5 passes I had reached all 6 continents with the cardboard antennas and I own a WAC-SAT for that. After a while I got a 85cm offset dish with a dualpatch feed for mode L/S, with 10W out from the IC-910. Until the unfortunate early death of the AO-40 in Jan. 2004 I was able to only take advantage of a total of 26 passes, made a total of 110 QSOs, both CW and SSB and reached 39 DXCC entities. I have made a sizable donation toward P3E and hope you all will too. 73 Werner, HB9US, AMSAT-DL # 302508, but since I have no AMSAT-NA #, noone over there will be interested in my comments anyway...

AO-51 Mode LS
by Matt 18 Sep '06

18 Sep '06

I had some luck with my AO-40 gear, MMDS downconverter - VK5EME preamp - 3' BBQ grill. But very limited comms. I am at a new location and my antennas and rotators weren't adjusted/calibrated enough for AO-51, and they were only installed last week. Got it sorted by Friday but az is still off by a couple of degrees. I kinda worked VK2RW Reg on the 13SEP06 @ 11:50z, but all we exchanged were call signs and the sat was at it's closest when I heard him/me. Then I lost it. By Friday and the weekend I was getting maybe 50 ~ 60% of the passes to my West, unlike my AO-40 days I have a lot of trees around me up to 30 degrees to my East and 15 degrees to my South. But it still was very tricky to work or find! SatPC32 couldn't get it right for the Doppler so I used my PCR1000 to find the downlink dialed in the 910 with the AFC on and i was ok from then. My uplink was a IC-T81a with a 16 Watt brick amp into 25 ele loop yagi with the memories set at 10 KHz intervals. So I think I was getting in ok I hope I didn't QRM anyone whilst trying. I have made some recordings of my downlink but it's only me calling CQ I forgot to record the QSO with Reg. With AO-40 it was easy to see how much error I had with my rotators and LO of my downconverter and so it made it easy to set up software like Satpc32 to accommodate for the difference. It's very hard to get it right will a LEO. I have started looking at S Band GEO sats so that I can remove all the errors in my setup. But all good ham fun I would like to see AO-51 in LS or VS more often in the future. Can AO-51 run LU? And what is the difference between DOVE's downlink and AO-51? DOVE seemed to be a lot stronger.

In FN00 I seemed to have the entire pass to myself. I did hear myself on a few occasions as I was sending out my call. I do have quite a few trees to contend with around my property so it is possible I could not hear others. I will be on the 9-18-06 00:25 UTC pass this evening.

Symposium Pre-Registration Extended
by Emily Clarke 16 Sep '06

16 Sep '06

Since most (about 90%) of Symposium Registrations have been through the website we have made a decision to extend pre-registration through the 24th of September. We were able to do this because the production cycle for badges, etc. is now automated and requires very little human intervention except some minor paper handling! So if you haven't signed up now is your chance to get in at the last minute without having to pay the additional fee! 73, Emily Symposium Chair --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Elmer Needed - LEO data and telemetry
by N6FO - Jim Cottle 16 Sep '06

16 Sep '06

Hi There, I would appreciate direct contact with someone here for extended questions regarding using WISP, etc for the TLM in the LEOs. I have no problem tracking GO-32 and AO-51, getting a good solid DCD during the pass but, try as I might, I cannot seem to get WISP to work. I get far more (albiet unrecognizable ASCII) when I simply connect to my TNC with hyperterminal. When I use WISP, I get nothing but files stuffed in the satellite directory. Anyone who wouldn't mind helping me with some stupid questions and linking up with me directly would be greatly appreciated. I am needless to say, not a fan of LEOs so far and would just like to use the digital capabilities at 9600 and 36K. My station is well equipped, but I have all of the tools and none of the talent. I am a fast learner, and have requested Martha send me a copy of the AMSAT guide (should be here any day now). I am tired of simply seeing my array track a 10 or 15 minute pass with nothing intelligible to show for it. I would like to read some telemetry? THANKS IN ADVANCE!!! I will return the favor once I am tutored. Jim N6FO San Francisco

S Band UP
by sco＠sco-inc.com 16 Sep '06

16 Sep '06

I now have 2m, 70cm and 2.4ghz antennas for satellites. The radio is a Ft-847 with receive SSB preamps on V and U bands. I have a BBQ dish with a SSB 2.4 ghz downconverter. That will work fine with P3E (it did with AO-40). Could I still use the same dish for S Band uplink on Eagle? I would need some form of a upconverter (from 70cm to 2.4 ghz) plus a amp, to make that work? If I am using the S band for the uplink which band am I using for the downlink? 2m or 70cm? Les W4SCO

Re: The Mode B tradition

What is the matter with everyone? If the guy next door is running WiFi on Channel 1, it is a very simple matter to ask him to switch to another channel, isn't it? It's just a simple software toggle. Any channel above 3 should be OK, and above 7 is out of the band! Laptops auto associate and find the channel, so only the channel in the AP needs changing. We're only talking about 100 mW sources (maximum!) here folks. Break out your wireless laptop, load up NetStumbler (free software) and go visit a couple neighbors. It's rather like solving a TVI problem in reverse, that's all. You can handle it! (HI) >From: "i8cvs" <domenico.i8cvs(a)tin.it> >To: "John B.

A emergency use for Eagle's digital side

Is it not what we are looking for in case of an > emergency "easy ready to use > stuff"? Luc: I hear what you're saying, but the case could be put the other way. I've learned a great deal on this list by discussing these things with you and others; I hope you won't mind if I present an opposing view below. Although the vision statement and User Classes don't specify this idea, I think we have to imagine that one important use of Eagle's high bandwidth data channel during a crisis would be to provide an Internet link to emergency service providers. I've outlined this in a previous letter to this list, but I can't find it on the web, so I'll describe it again. I believe that the best thing you can do for emergency services is to allow them to use the communication tools with which they are most familiar: email, chat, even web forms and the like. Yes, people are trained in other means, but in our day-to-day interactions, TCP/IP rules. Putting this in Luc's terms above, the 'easy to use stuff' should be easy for the emergency folks, first and foremost; and today, easy means Internet. If that's the case, Eagle's data link could provide a pool of Internet connectivity within a striken area, allowing workers to do their thing as naturally as possible. I believe 256 kbps was the max mentioned in the recent article. A ground station with a sufficient Internet connection (perhaps one associated with an educational institution), would provide one end of the connection with a solid link to Eagle. The small dish station envisaged by the Design team, connected to a wireless laptop would provide the other end. Indeed, using a Knoppix-like boot disk, any laptop with remotely appropriate hardware could do the job. This laptop's wireless would act as a managed mode 802.11 hub. Then, our emergency workers just boot up their hardware, and they're there: emailing, using online chat, uploading photos and videos, whatever. 256 kbps could be split pretty far. Note, however, that with this use, the station is right in the middle of the 802.11 activity. If it were unable to hear well under such circumstances, this use would not be possible. (QRM'ing the emergency 802.11 traffic isn't a problem: the link laptop would be configured to make its connections on an unaffected 802.11b/g channel.) The world and the ham community has the right to ask us to justify our dedicated bandwidth. I think the picture above has the virtues of being both compelling and honest: I think Eagle could not only give us all a great deal of fun, but also improve some peoples' lives in hard times. For this reason, I think we should lash up an Internet link of this sort as soon as the digital side starts to come together, put it at either end of the Dayton Hamvention, show it off at other events, play with it across town as part of the QRO 802.11 links that hams are already exploring. Our message should be this: "Eagle's mode UV will be cleaner and more fun than any P3 bird; and Eagle's emergency capabilities will be out of this world." In saying this, I do not mean to reject the well-thought out caveats and concerns expressed on this list, but I do want to register my enthusiasm for the digital vision of the Eagle series, especially as tweaked above. Respectfully, 73, Bruce VE9QRP

Preamp protection
by Angel Peláez, EA4DUT 15 Sep '06

15 Sep '06

Hi everybody: I'm looking for the schematic diagram of a preamp protector against TX. I know the impressive quarter wave design with square brass stock and clamping diodes for 432 EME which Domenico, I8CVS, described I don't remember where. Rather I'm looking for something much compact as I would like to use from VHF to above. I mean one of these small boxes (RF diode clippers???) I see sometimes on commercial pages which promises withstand 25W for a short period I'll appreciate any comment about the issue. Thanks in advance.

As I understand it, the plan is to have this link working 24/7. (Yes it will primarily use a software-driven transponder, but that will be transparent to the analog user.) In this regard, I can't see how the design team can be accused of unnecessarily innovating. 73, Bruce VE9QRP Hello Bruce / Dom. I agree, the UV on Eagle will be apparently analog (ue) to the casual user. But be aware Bruce that it's not "primarily" a software driven transponder. It is in fact TOTALLY software driven. There is no linear IF, just DSP in the core. Or from another viewpoint 100,000 single point failures just waiting to happen. 73 David G0MRF

Video working FO-29 from mobile
by Pedro EB4DKA 15 Sep '06

15 Sep '06

Hello list, I have put a video working the FO-29 from mobile in my website. The setup is: Uplink: Kenwood TM-255 (40W) + 1/4 wave VHF magmount whip. Downlink: Kenwood TH-F7E + CJU antenna + a pair of earbuds (there is a mp3 recorder between the F7E and the earbuds for the audio of the video). The pass was 39 degrees max. elevation for me in IM79DC. There was a little RF QRM from a near factory (at about 300 meters). The direct link to the video is http://rcfo.batcave.net/fo29movil.html but you can access it from my website www.eb4dka.tk in the videos section. Thank you very much Domenico I8CVS and Peter DL3JIN for helping me doing the video! Best 73 to all, Pedro EB4DKA http://www.eb4dka.tk http://miguel.servihosting.com/eb4dka eb4dka(a)amsat.org

Re: The Mode B tradition
by John Champa 15 Sep '06

John, The WiFi QRM you experienced on Mode S was probably a WiFi Channel 1 device. Some APs use that for a default channel, although most use Channel 6. Did you try using NetStumbler (free software) to determine location? At 100 mW nominal maximum RF power it must be a very local source. Many times you can just ask them to move to one of the channels 7 - 11 (simple software toggle), which in the US, is outside the 2.4 GHz Amateur Band. Just a suggestion. It's kind of like solving a TVI problem, but in reverse (HI). 73, John - K8OCL >From: "John B.

OSCAR-13 Mode-S User List ( Update 15 september 2006 )
by i8cvs 15 Sep '06

15 Sep '06

Hi , All Here is the last update 15 Sept 2006 of OSCAR-13 Mode-S user list. Just for record i have included a list of OSCAR-13 operators with their call letters and antennas used for downlink Mode-S from 2400.711 to 2400.747 MHz during the lifetime of this glourious U/S transponder The power of OSCAR-13 mode-S was only 1,5 W pep and the satellite antenna was an helix with G=10 dBi and so EIRP=15 W pep In comparison the power of S1 TX on AO40 was 50 W pep and the antenna was an helix with G=10 dBi and so EIRP=500 W pep i.e. 15 dB easyer than OSCAR-13 The power of the next P3E will be 38 watt pep with a similar antenna. The mode-S transponder of OSCAR-13 was "hard limited",in other words no AGC was in it and so the 1,5 W pep available for all users was proportional to the uplink power. At epoch time of this list, first originated by W4FJ on 14 jan 1994 it was very difficult if not impossible to find ready to operate preamplifiers/converters antennas/antenna feeds for 2.4 GHz and the most part of the equipments where necessarily hombrew by amateurs. In addition,at that time about 15 years ago,the best GaAsFET available at amateur price showed a noise figure not less than 1 dB at 2400 MHz Even though the list of users of OSCAR-13 Mode-S in the early 1990 -1994 is very long.

All: It has come to my attention that the San Diego meeting report has format problems. I've ZERO idea how the format got gooned. I have taken it offline for correction. I will advise, tomorrow or Saturday, when I've fixed the format and reloaded. Thanks & 73, Jim wb4gcs(a)asmat.org James A. Sanford, PE Amsat Eagle Project Manager

The Eagle has died, my original point.
by Keith Bainbridge 15 Sep '06

15 Sep '06

As I started this thread perhaps I should finish it. My original point was the ratio of Satellite operators to experimenters must be about 50:1, so it makes far more sense to put up a bird that people will and more importantly " can " use than continually developing more and more sophisticated modes etc. The biggest thrill I've had in 25 years as a Ham is to work 67 countries and all continents in the 18 months or so that I discovered AO-40. I'd played with AO 7 etc back in 80-81 but this was " FUN " and thats the point I tried to make with my earlier post. I will donate to P3E as it will give me many options to use the gear I already have. There are no other options for me, living in Western Australia, Leo's are a complete waste of time and money, I can talk to myself on every pass on any satellite going over, no one else will be there to reply !! Well maybe the same 2 or 3 people. If Amsat NA must persue the Eagle option then please be prepared to revert back to AO-13 / AO-40 type birds when it fails. Can we finish this hread of mine now please? 73 Keith -- Keith Bainbridge VK6XH & VK6DXR Vice-President Northern Corridor Radio Group ( VK6ANC ) Amsat NA 35338 TenTec Omni VI, FlexRadio SDR 1000 , 5 Band Spiderbeam.
