I: Doppler correction - HRD 5.0 compared to SatPC32
by Francesco Grappi 17 Jan '10

17 Jan '10

Hi, SatPc32 works perfectly for doppler correction also on my Kenwood TS-790E and Yaesu FT-736R. Thank you to Erich DK1TB, great job ! 73" Frank IW4DVZ -----Messaggio originale----- Da: amsat-bb-bounces(a)amsat.org [mailto:[email protected]] Per conto di PE0SAT Inviato: domenica 17 gennaio 2010 23.04 A: amsat-bb(a)amsat.org Oggetto: [amsat-bb] Doppler correction - HRD 5.0 compared to SatPC32 Hello, I would like to share an experience and ask this board if others have the same? I have used Ham Radio Deluxe for two years but have recently switched to SatPC32. The reason is that the Doppler correction of HRD with my Yaesu FT-847 always gave problems. It was a constant battle to stay on frequentie. I would like to continue using HRD but the Doppler correction compared to SatPC32 is just bad. Now I wonder, are there others that use HRD that share this experience or is it something only occurs in combination with the Yaesu FT-847 and is there maybe a solution. 73 Jan - PE0SAT _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Life Members
by Jeff Davis 17 Jan '10

17 Jan '10

In the ongoing "discussion" about the new mailing list policy (kudos to the BoD by the way), the "Life Member" label has been at the forefront as though this adds gravitas to the opinion of the commenter. Since we are going down that path, I just wanted you to know that when I read "Life Member" I hear the words "cheap", "discount", "looking for a deal", "old fart" in my head. The fact that you paid a hugely discounted price twenty-five years ago for a "life" membership and now lean heavily on that previous investment to denigrate the organization makes your opinion considerably less valuable to me than had you paid the "full freight" for those same years. I realize it can be painful to discover that others have opinions too, but if I have to read this constant drivel then you must read mine. I've been a member since 1994 and have always paid the full membership fare, each and every year. In addition to President Club membership and associated donations... So there! What have YOU done for the hobby lately? Jeff, KE9V

If you use the calculator that I referenced you will come out with the figures that I quoted. There are several ways of measuring the worth and those are shown on the calculator. Using the consumer price index as the basis the figures are correct. Using other things as the basis you will definitely come up with different figures.

To All: I have had many replies to my query concerning logging software that supports accurate transfer of log data to LoTW and eQsl in the ADI format. To keep the traffic low on the BBS, I have answered each of you via your own E addresses. In a public way I want to say thanks to each person who responded. You have been a great help to a fellow that doesn't know much about software choices. The AAlog is the one I choose and I have saved all other information for future reference.

Thanks to all who expressed an interest in the qso between WC7V and RN1NW on ao7b. I have hoped to make this contact for over 30 years. The fact that it happened is thanks to Oscar 7 and Ted, RN1NW was 559 even as ao7 approached his horizon. The satellite was ascending at my qth and at about 3 degrees at the end of our qso. The QSO took place on orbit #60960 at 16:08Z. I had heard RN1NW a couple of days prior but didn't make the contact. Because of ao7's history and bright future, I think any contact on this satellite is a record.

Based on a worse-case, 600km orbit, we can produce a whole-orbit power budget of 7.5 watts using a 3U CubeSat design. If a spacecraft is launched into a more optimal orbit, like a sun-synchronous orbit, one of the two Pseudocapacitor banks can be removed. The design can be scaled to be used with other classes of spacecraft - 2U/1U CubeSat, Microsats, etc. The design has gone through two reviews with AMSAT Engineering. (Thanks Lou, Barry & Tony!) (b) We have a light-weight deployable solar panel design with integral magnetorquer coils for attitude control. The design contains original research and integrates CubeSat research from: * University of Delft (hinge concepts & use of Dyneema wire) * University of Illinois at Urbana-Champaign (flex-circuit magnetorquers & carbon-fiber substrate) * the Aerospace Corporation (thin-film attachment of solar cells) The design will produce about 12-15 watts per minute in any orientation (worse-case) for 3U, less with 2U or 1U If a spacecraft is launched into a more optimal orbit the number of solar cells can be reduced while maintaining the power budget (c) We have analyzed the existing AMSAT spacecraft modules (from ARISSat & P3D) and determined that: * We can fit the SDX and U/V Linear Transponder systems from ARISSat into a 2U or 3U CubeSat Chassis without significant re-design * The IHU is going to be slightly redesigned to incorporate the Command Decoder board functions * We can reuse the base concepts from P3D for the Sun & Earth Sensor Systems * We can reuse a 3-axis Magnetometer design (Honeywell) * If the ARISSat boards were redesigned/repackaged they could fit within a 1U Chassis. (d) Things to do between now and Dayton: * Complete thermal analysis of a baseline 3U spacecraft * Antenna design (based on U of Delft's spring steel U/V antenna deployment system) * Complete Attitude Determination & Control (ADAC) integration (magnetorquers, sun/earth sensors & magnetometer) * Finish building engineering model This R&D, being performed by Engineering Students for their Senior Design projects (8 ME's/EE's + 26 SE's), is being sponsored by AMSAT. So I encourage everyone to contribute what you can to AMSAT to help fund spacecraft systems development and launch opportunities. If we have reliable, lower-cost, modular systems, then AMSAT can be more responsive to any launch opportunity. We'll have more info on the research we're doing in the next issue of the Journal and look for us at the AMSAT table in Dayton! Alex Harvilchuck, N3NP NextGen CubeSat Program Manager

TS-2000 70cm Tx problem with AO 7
by Starr 17 Jan '10

17 Jan '10

Hi All, After a number of years of being inactive satellite (artificial) wise, I am having fun trying them out again. I have a TS-2000X, one of the earlier models, and I have just installed Version 5 of Ham Radio Deluxe in the shack computer, (great software), to control the radio The problem I have is; while transmitting on 70cm and the frequency is changing to compensate for Doppler change, the radio often stops and the display shows dashes in the places where the frequencies were shown. The power to the radio is recycled to get it working again. If my memory serves me correctly there was a fix mentioned for this problem a few years ago. Any help would be much appreciated. 73 Starr ZL3CU AMSAT ZL member

For those who are still dreaming for a HEO in the mean time just check below you can have your own LEO/tube sat satellite for 8000$ launch included payable with the major credit card and you even have payment options! I'm just waiting to see one of them on E-Bay As they said "TubeSats are designed to be orbit-friendly. Launches are expected to begin in December of 2010." Probably the replacing solution for our aging AMSAT-NA satellite fleet? Anyone with 8000$ can own his own satellite let me guess in a couple of years the same repeater frenzy will also reach the amateur satellite world. No more need of club or organization or IARU frequencies coordination .

Re^2: FO-29 schedule Jan, Feb.
by Mineo Wakita 16 Jan '10

16 Jan '10

The TX will be ON till the Voltage Controller (UVC) decided to switch OFF. Now FO-29 is still in eclipses. For example, if the TX will be switched on at 2100 UTC on Jan 16, then it will be switched off by UVC at 21:24 UTC due entering the eclipse. I understand it from the chart below. Black boxes are the eclipses. Yellow means sunlight (percent of illumination). You can see that FO-29 is not free of eclipses but they are getting more and more shorter. FO-29 is will be switched on after a eclipse and UVC will switch off if the satellite enters the eclipse (a black box). And you can see the last eclipse will be on Feb 08 at 00:15 UTC -> after then we have no eclipses anymore. You can also use a satellite software like Orbitron to simulate the orbit and the satellite illumination. http://www.ne.jp/asahi/hamradio/je9pel/00116f29.jpg Tnx. DK3WN, Mike JE9PEL, Mineo Wakita

FT3000m on FM sats
by Juan Antonio Fernandez 16 Jan '10

16 Jan '10

Hi John I have a FT300M in my movil station for years. It works great with FM sats with 1/4 whip on the roof. You will only need a headset if you want to work in full-duplex, although in half-duplex also works fine beacuse of its high power, near of 70 Watts. But I enjoy receiving with a UHF hand held HT and a CJU antenna attached to it and using the FT3000M with a 1/4 whip antenna to uplink.

AMSAT adopts Use Policy for AMSAT mail lists The AMSAT Board of Directors unanamously adopted an Acceptable Use Policy for the AMSAT Public Mailing Lists on January 5, 2010. This policy takes effect immediately and applies to all those using the AMSAT mailing lists. The policy can be read below in text format or is available via a link on the front page of the amsat.org Web site or directly from this link http://www.amsat.org/amsat-new/images/fck_images/AMSAT%20AUP.pdf Following the October 2009 AMSAT Board meeting Gould Smith, WA4SXM AMSAT VP of User Services appointed a committe to develop a use policy for the mailing lists. The members of the committe did an outstanding job of putting together a document that is acceptable to all the committe members and was passed without change by the BoD. Thank you to the committee members: Stephen Belter, N9IP; Alan Biddle, WA4SCA ; Mark Hammond, N8MH; Samudra Haque, N3RDX ;and Paul Williamson,KB5MU. The policy will be added to the AMSAT Web site and included as part of the process when applying to join any of the AMSAT mailing lists. ================================================================================ Acceptable Use Policy for the AMSAT Public Mailing Lists Approved by the AMSAT BoD 5 January 2010 The AMSAT Bulletin Board (AMSAT-BB) public mailing list carries general AMSAT information and discussion. The purpose of this mailing list is to provide a forum for general discussion of any satellite-related topic. The Space Amateur Radio Experiment (SAREX) public mailing list contains information and discussion pertaining to amateur radio operation on manned space missions, including the Space Shuttle, Mir (formerly), and the International Space Station. The name is leftover from the Shuttle Amateur Radio Experiment (SAREX) aboard Space Shuttle flights. It is now mainly concerned with ARISS operations aboard the International Space Station. There are also regional AMSAT public mailing lists (e.g., AMSAT-DC, AMSAT-Florida, and AMSAT-NE) and numerous private mailing lists (e.g., Board of Directors, Officers, AO-51 operations, etc.). Anyone can read the messages posted on any of the public mailing lists, and many people from around the world do so. Our audience includes AMSAT members, board members, and officers. At any given time, the readers may also include amateur radio operators, shortwave listeners, minors, potential financial donors, potential launch providers, officials from other amateur radio and satellite organizations, officials from international space agencies, and equipment suppliers and manufacturers. Since the archives of the public mailing lists are available on the AMSAT website, the contents of individual messages are easily found using common search engines. Because of this wide readership, AMSAT insists that messages posted on its public mailing lists conform to this Acceptable Use Policy (AUP). Acceptable Content We embrace diversity of opinions and values. In order to preserve a constructive environment, we do insist that messages contain appropriate content and are respectful of the members and readers of the list. All posts should include the author's first name and call sign, or full name if not currently licensed. In general, messages for the AMSAT mailing lists should be related to amateur radio satellites. Examples of on-topic posts include: * Announcements of general interest, including but not limited to AMSAT news, meetings, satellite availability, and DXpeditions. * Technical discussions, including the physics of space flight, modulation techniques, satellite design, RF path loss calculations, noise figure, etc. * Inquiries and suggestions about choosing equipment, learning operating techniques, and troubleshooting problems. * Discussion of AMSAT plans and policies in ways that foster better understanding of the opportunities, trade-offs, and limitations that AMSAT faces, and constructive suggestions for improvement. * Posting of amateur radio satellite-related equipment and software available for sale. Unacceptable Content Strong disagreements on issues are inevitable, but the AMSAT mailing lists are not the place for exchanges which become spiteful, unproductive exchanges. If you must have a heated exchange, it should be conducted privately and not in public on a mailing list. We define unacceptable content as anything that is: * Illegal * Insulting, abusive, harassing, or threatening * Knowingly false or misrepresentative Enforcement of this AUP Access to the AMSAT mailing lists is a privilege and not a right. While these rules cover most common situations, they cannot anticipate everything. Consequently AMSAT reserves the right to take any actions it deems appropriate to ensure these forums are not disrupted or abused. Violators of this policy may be subjected to manual moderation or have their ability to post messages suspended. Violators may or may not be warned prior to enforcement. If you feel that you've been unfairly blocked from the list, you may appeal your situation in writing to: The Radio Amateur Satellite Corporation Attention: AMSAT-BB 850 Sligo Avenue, Suite 600 Silver Spring, MD 20910 Your letter of appeal will be forwarded to the VP of User Services and the Director of Electronic Communications for consideration.

You know, that First Amendment thingie: "Congress shall make no law respecting ... abridging the freedom of speech ... " This messagegroup - and millions of others - is a private party. NOT government-run nor sponsored. We're mere visitors entering and using it, and we have to abide by its rules - else we go elsewhere. Like guests in your home, there's an expected set of rules for behavior, and AMSAT just laid them out in black and white. Similar to a Web site's "user service agreement" - a concept and device I've been using for my sites' visitors for over twenty years. A properly-drafted user service agreement spells out what I promise to you as the Web site owner, and what I expect from you as a visitor. Kinda like shaking hands before you peruse my sites.

The whole issue revolves around just a few members/posters who continually try and push the boundaries on what is a large list with respected and influential members all over the World. We all know who they are; the ones that immediately post a facetious reply to a newbie question, the ones that post one line,or worse still, one word answers that are ambiguous at best and downright rude at worst; the ones that take childish delight in trying to elicit the maximum controversy with seemingly innocuous postings. We know who they are and they know who they are and the laws of defamation restrict me in naming them! There is a delete key on your keyboard; there are message filters built in to your e-mail client and if you really get offended then there is always the "un-subscribe" route. But if anyone on the list ever gets to having to be warned by AMSAT about their conduct on the BB or worse still, be faced with suspension/expulsion from the list then shame on you! For the most part we are all responsible adults involved in a fairly expensive hobby (note "hobby") that is both highly technical and to most people, quite complicated. If anyone feels that they can do a better job than anyone on the current Board then by all means file a motion of no confidence and see how many fully paid up members back you. Put up or shut up. That we have even had to come to an Acceptable Use Policy for this board should make certain members/posters question whether they should even be members.

Has anyone on the list used a Yaesu FT3000M on the Mode J FM sats? Does it have pretty good receive sensitivity for the birds? Can it do full duplex, where you can hear your own downlink? What I have seen written about it seems to indicate that it can. Any other comments-good or bad-about this model? 73s John AA5JG

OSCAR-11 Report
by Clive Wallis 14 Jan '10

14 Jan '10

OSCAR-11 REPORT 14 January 2010 This report covers the period from 30 November 2009 to 14 January 2010. During this time the satellite was heard briefly on 10 & 11 December and then from 31 December until 10 January. Good signals were received, and decoded. Sometimes signals have been very strong, although frequent changes in polarisation have been observed. The satellite was not heard during solar eclipses, which now occur during the afternoon and evening passes over the UK. The last two 'off' periods have lasted 14 and 19 days respectively, suggesting that the watchdog timer has been reset. However, the last transmission period lasted for the full ten days, so it is possible that transmissions may resume after ten days of silence, ie. around 20 January. However, please note that the satellite's behaviour is now very unpredictable, and until a pattern of operation is established, it is impossible to predict what will happen next, with any certainty. The telemetry is unchanged from the 2008 downloads. The on-board clock is now 252 days slow. When last received in 2008 it was 83 days slow. The increasing error suggests that the clock may be stopping, when the satellite is in eclipse. During the last transmission period the date failed to increment on one occasion, from 29 to 30 May. ------------- RECEPTION REPORTS REQUESTED! Please send reception reports to xxxxx(a)amsat.org (replace xxxxx by g3cwv) or post to amsat-bb. If you have a file, please discuss it with me, before sending it! You may also like to add your reception report to the live satellite status page, on the website set up by David KD5QGR and Bob WB4APR. The URL is http://oscar.dcarr.org/index.php The satellite transmits on 145.826 MHz., set receiver to NBFM. OSCAR-11 has a characteristic sound, rather like raspy slow morse code, sending "di di dah dah dah dah dah dah dah" sent over five seconds. If you are receiving a very weak signal, switch the receiver to CW or SSB. You should hear several sidebands around the carrier frequency, should be able to hear the characteristic 'morse code like' sound usually on at least two of the sidebands. Please note that you need a clean noise free signal to decode the signals. There is an audio clip on my website www.g3cwv.co,uk which may be useful for identification and as test signal for decoding. ------------- Reception reports have been received from Peter ZL3TC, Mike DK3WN, Jon 2M0IBO and Detlef DJ3AK. Many thanks for those. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF The satellite is now subject to eclipses during every orbit. Long term predictions indicate that eclipses will occur until 2019, when there will be some eclipse free periods until 2023. However these very long term predictions should be regarded with caution, as large tracking errors can accumulate over long periods of time. When analogue telemetry was last received in March 2005, 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 25 years in orbit the battery has undergone over 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses lasting more than about ten minutes, or sometimes even during periods of poor solar attitude. Study of the satellite's behaviour prior to 2008 suggested that its battery would not sustain operation during solar eclipses, and the watchdog timer would switch the satellite OFF after less than an orbit. Eclipses are now occur during every orbit and will continue for many years. In practice this meant that OSCAR-11 would only be heard occasionally by stations monitoring the frequency while listening for other satellites. The satellite unexpectedly started sustained transmissions during November 2009, suggesting that there may have been a failure causing reduced drain on the power supplies or a change in the watchdog timer characteristics. 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 may show an error of +40 days for some dates. The time display has switched into 12 hour mode. 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. 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. 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 last telemetry received from the satellite is available for download. 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.

AO-51 and Wisp
by Robert 12 Jan '10

12 Jan '10

Hi! I am able to recv a good amount of data from AO-51 utilizing the AO-51 tlm program. Unfortunately, I am not able to collect any data thru wisp. I'm pretty sure I have the app setup correctly but never see any messages show up. Had better success years ago with AO-16 and running PB. Is there a way to get data into the program to check it operation rather then wait for passes? I notice from the data I see utilizing TLM that I see a string PB-list empty does this mean there are no messages ? Appreciate any feedback but a pointer to more wisp help aside from mineo's site would be appreciated. Cheers BOB K0TZ

SatPC32 and CAT control
by n1jez＠burlingtontelecom.net 11 Jan '10

11 Jan '10

I have a weird one. I'm trying to help another ham out. He has an FT-847 running SatPC32. He's trying to get Doppler correction working. SatPC32ISS works fine. The radio tunes as it should. SatPC32 does not tune. When he hits C+, the radio will go into Sat mode and preset the freqs, but when the satellite is in view, the radio doesn't tune. He can manually tune the radio with the up/dwn button on screen. Ideas? 73, Mike, N1JEZ AMSAT 29649 "A closed mouth gathers no feet"

WD9EWK at Glendale AZ "WestFest" - report
by Patrick STODDARD (WD9EWK/VA7EWK) 11 Jan '10

11 Jan '10

Hi! Sorry for the delay in posting this report. Between fighting off a cold and spending much of the weekend at work, I am getting caught up with things like this. The WestFest hamfest in Glendale AZ, a west-side suburb of Phoenix, is the only indoor hamfest in the Phoenix area. Ever since it became an indoor event, it has been popular. The ThunderBird Amateur Radio Club, sponsor of this hamfest, has been gracious in providing a free space for AMSAT at their hamfests for the past few years. I have done presentations and demonstrations at 3 different club meetings over the past 3 years, so I looked forward to the hamfest on Saturday morning. I was still setting up my table when the first AO-51 pass came by in the 1300 UTC hour, and I was talking to a bunch of hams through the second AO-51 pass. I did go outside and work the first VO-52 pass to the east around 1600 UTC. I heard WA4HFN in Tennessee clearly, but he had issues hearing my callsign. Jim KE4KOL also worked me on that pass, where I had my FT-817s in a duffel bag to illustrate the portable nature of my gear. I was outside for an SO-67 pass after this, but nothing was heard. I thought that there might have been an issue with my setup, until I saw KD5QGR's status page and AA5PK's report that he also didn't hear the satellite. So I went outside to work the SO-50 pass around 1800 UTC, near the end of the hamfest. This was the most productive pass, and thanks to all the stations that called me. I have to tell a quick story... Norm WV7K, a local ham who used to be very active on the satellites, stopped by my table at the hamfest in Mesa AZ last month with his son David. David got his license a few months ago (KF7DRQ), and appeared to be interested in satellites. Norm still has lots of his satellite gear, but they both were interested in my demonstrations. We talked a bit at that hamfest, and I gave them copies of a flyer to get started on the FM satellites. Fast forward a few weeks to last Saturday, and they were both at this hamfest. David had an HT, and needed an antenna to try the satellites. A vendor had Arrow antennas, and Norm had a diplexer at home that could be used with the dual-band Yagi. They bought the Yagi, saw my SO-50 demonstration at 1800 UTC, and a few hours later David made his first satellite QSO using his HT and new Yagi on AO-51 with K4YYL in South Carolina. I apologize if anyone was looking for me on the passes I did not show up on. Even with trying for 3 passes and working 2 of them, the demonstrations were well received. The SO-67 pass where we heard no downlink signals was also a good time with lots of questions and answers for the crowd that followed me outside. As always, thanks to all who called me during those other two passes, especially mentioning your location along with your callsigns and grids to better illustrate the coverage of these satellites. 73!

Quartzfest 2010 anyone?
by Tom 11 Jan '10

11 Jan '10

Anyone planning on attending the week-long Quartzfest 2010 hamfest (http://www.quartzfest.org) near Quartzsite, Arizona next week? I'll be there Jan 15-23. If any other sat operators plan to be there maybe we could meet up. I know there's usually a good turn-out from W6-land. I'll be operating the FM birds from DM23vn throughout next week. If anyone needs that grid square and works me just an email to 'my call' at amsat.org and I'll mail you a QSL card if you're in my log. Tom, KØTW

[Fwd: SOSS - Save our Space-comms Systems]
by Tim Tuck 10 Jan '10

10 Jan '10

Saw this on moonNet - thought it should also be seen here. regards Tim -------- Original Message -------- Subject: [Moon-net] SOSS - Save our Space-comms Systems Date: Mon, 11 Jan 2010 11:58:32 +1100 From: Robert Brand (EOA) <robert.brand(a)echoesofapollo.com> To: <moon-net(a)list-serv.davidv.net> At Echoes of Apollo, we are starting a group called "SOSS" - Save our Space-comms Systems. It is to set up suitable entities in countries around the world to save, preserve, manage and operate large infrastructure for space and science outreach under the control of mentors. The sites may be tracking, comms or radio astronomy and we will look to funding from a variety of stakeholders including government grants. Where possible the groups would be "Not For Profit" and in some countries donations would be tax deductible. It is early days and I expect that we will be able to make some of the dishes available for the occasional EME event. I look forward to comment and contributions from anyone interested For those on Facebook I have set up a test group and already have over 200 interested in just one day. You can join the group at: http://www.facebook.com/Echoes.Of.Apollo?ref=profile#/group.php?gid=23924300 3946 I also accept all friend requests Overview: "A space outreach program worthy of support. Combining preservation, green initiatives, science outreach, hands-on for students and mentoring from senior experts in the fields of space comms, space tracking radio astronomy and amateur radio." Description: "This group is looking at ways to protect and manage retired space communications systems and put them into service for space science outreach and student education. Historic and useable systems are being scrapped all the time. It is essential that these be protected and used to stimulate students and the general public in space as a career opportunity, both in space/satellite communications or radioastronomy. This is a global group and will need local support to save any infrastructure in a particular country. I have lists of aging infrastructure in Australia and USA at this time. We will look for grants, sponsorship, volunteers, support and donations. We will need country reps and lobbyists. It is essential that we preserve our heritage and our future in space."

HAM RADIO UNIVERSITY-2010
by Peter 10 Jan '10

10 Jan '10

Thank you, I want to extend my appreciation for the stations that made my Satellite Demonstration, of AO-27, at 18:50 today an exciting success using the special event call sign of W2V. If you would like a special event QSL card, please send your information to WB2OQQ(a)AMSAT.org. I gave an earlier satellite presentation on How to get into space with an HT. I had over 43 interested Amateur Enthusiasts that attended the talk, we all had a great time. I want to thank Clint K6LCS, for his ideas on how to excite a group, Tim N3TL for sharing his 2008 Symposium presentation, that highlighted how you can be successful with a handheld and 400 milliwatt's. Pat WD9EWK, who has put his informative slides on the AMSAT Fieldops section and his e-mails to me on how to make a solid presentation. The feedback from the attendees was very rewarding, they took away a feeling that making satellite contacts is not as difficult or expensive as they thought. I could not have done it without your help guys and the knowledge shared on this BB, thank you. 73, Pete, WB2OQQ AMSAT NY Area Coordinator

Delfi-C3 update January 10 2010
by wouter weggelaar 10 Jan '10

10 Jan '10

Hi all, Recently, we have released an updated version of the RASCAL software for the reception of Delfi-C3 (DO-64) telemetry. You can grab a copy at http://www.delfic3.nl/rascal If you already have RASCAL installed, you can use the upgrade package. The upgrade package leaves all your settings intact. Improvements: - Current & voltage of reference diodes added. This is a measure for the solar intensity received on the solar panels. These diode outputs correlate with the output of the TFSC measurements, and can be found in the IV-curves window (Options -> Show IV Curves) - AWSS data presence indicators added. These indicators light up green if data from the sun sensors (AWSS) is received, and in which quadrant there is data. The AWSS data presence indicators can be found in the lower right corner of the RASCAL main screen. In the mean time, Delfi-C3 is still in good health and performing fine in science mode. The total number of frames as of today is 849670 (approx. 121.5 MB) and the number of registered users is now at 335. Many people are submitting data on the guest account (RASCAL default). Delfi-C3 has been on orbit for 622 days and her second birthday is coming up on April 28th. There are no signs of considerable degradation in science mode, so everything is still healthy. Thank you for your continued support and efforts to receive and send in telemetry data. 73 and Happy new year on behalf of the Delfi-C3 / DO-64 team, Wouter Weggelaar PA3WEG

Since this news was not (yet) shared via this BB (as far as I am aware); We do hear since a few days one of the ANDE-2 satellites again: Castor (KD4HDO-1) transmits every 30 seconds an APRS telemetry beacon at ~145.827 MHz. For those with an accurate clock: at ~28 and ~58 seconds in each minute. .. yes, this is on the uplink of other satellites, including HO-68 (XW-1, Hope-1), interesting ! http://www.findu.com/cgi-bin/raw.cgi?call=kd4hbo-1&start=100&time=1 http://www.dk3wn.info/p/?cat=38 (Mike's SatBlog) 73, Henk http://www.pa3guo.com

Azimuth question
by Randy 10 Jan '10

Is azimuth base on true or magnetic north When lining up the antenna system for satellites? When I looked it up, says true north. Is that true for ALL satrellite tracking software? One website says 12 degrees 58 seconds West is the magnetic declination. So does that mean turn my antenna west by that amount from Magnetic north? Randy - N2CUA

January 10, 2010 To All RADIO AMATEURS BID: $ANS-010.01 The AMSAT Board of Directors unanimously adopted an Accepted Use Policy for the AMSAT Public Mailing Lists on January 5, 2010. This policy takes effect immediately and applies to all those using the AMSAT mailing lists. Following the October 2009 AMSAT Board meeting Gould Smith, WA4SXM AMSAT VP of User Services appointed a committee to develop a use policy for the mailing lists. The members of the committee did an outstanding job of putting together a document that is acceptable to all the com- mitte members and was passed without change by the BoD. Thank you to the committee members: Stephen Belter, N9IP; Alan Biddle, WA4SCA; Mark Hammond, N8MH; Samudra Haque, N3RDX; and Paul Williamson, KB5MU. The policy has been added to the AMSAT Web site and will be included as part of the process when applying to join any of the AMSAT mailing lists. The link to the PDF file can be found at: http://www.amsat.org Acceptable Use Policy for the AMSAT Public Mailing Lists Approved by the AMSAT BoD 5 January 2010 The AMSAT Bulletin Board (AMSAT-BB) public mailing list carries general AMSAT information and discussion. The purpose of this mailing list is to provide a forum for general discussion of any satellite-related topic. The Space Amateur Radio Experiment (SAREX) public mailing list con- tains information and discussion pertaining to amateur radio opera- tion on manned space missions, including the Space Shuttle, Mir (formerly), and the International Space Station. The name is left over from the Shuttle Amateur Radio Experiment (SAREX) aboard Space Shuttle flights. It is now mainly concerned with ARISS operations aboard the International Space Station. There are also regional AMSAT public mailing lists (e.g., AMSAT-DC, AMSAT-Florida, and AMSAT-NE) and numerous private mailing lists (e.g., Board of Directors, Officers, AO-51 operations, etc.). Anyone can read the messages posted on any of the public mailing lists, and many people from around the world do so. Our audience includes AMSAT members, board members, and officers. At any given time, the readers may also include amateur radio operators, shortwave listeners, minors, poten- tial financial donors, potential launch providers, officials from other amateur radio and satellite organizations, officials from international space agencies, and equipment suppliers and manufacturers. Since the archives of the public mailing lists are available on the AMSAT website, the contents of individual messages are easily found using common search engines. Because of this wide readership, AMSAT insists that messages posted on its public mailing lists conform to this Acceptable Use Policy (AUP). Acceptable Content We embrace diversity of opinions and values. In order to preserve a constructive environment, we do insist that messages contain appro- priate content and are respectful of the members and readers of the list. All posts should include the author's first name and call sign, or full name if not currently licensed. In general, messages for the AMSAT mailing lists should be related to amateur radio satellites. Examples of on-topic posts include: + Announcements of general interest, including but not limited to AMSAT news, meetings, satellite availability, and DXpeditions. + Technical discussions, including the physics of space flight, modula- tion techniques, satellite design, RF path loss calculations, noise figure, etc. + Inquiries and suggestions about choosing equipment, learning operat- ing techniques, and troubleshooting problems. + Discussion of AMSAT plans and policies in ways that foster better understanding of the opportunities, trade-offs, and limitations that AMSAT faces, and constructive suggestions for improvement. + Posting of amateur radio satellite-related equipment and software available for sale. Unacceptable Content Strong disagreements on issues are inevitable, but the AMSAT mailing lists are not the place for exchanges which become spiteful, unproduc- tive exchanges. If you must have a heated exchange, it should be conducted privately and not in public on a mailing list. We define unacceptable content as anything that is: + Illegal + Insulting, abusive, harassing, or threatening + Knowingly false or misrepresentative Enforcement of this AUP Access to the AMSAT mailing lists is a privilege and not a right. While these rules cover most common situations, they cannot anticipate everything. Consequently AMSAT reserves the right to take any actions it deems appropriate to ensure these forums are not disrupted or abused. Violators of this policy may be subjected to manual moderation or have their ability to post messages suspended. Violators may or may not be warned prior to enforcement. If you feel that you've been unfairly blocked from the list, you may appeal your situation in writing to: The Radio Amateur Satellite Corporation Attention: AMSAT-BB 850 Sligo Avenue, Suite 600 Silver Spring, MD 20910 Your letter of appeal will be forwarded to the VP of User Services and the Director of Electronic Communications for consideration.

January 10, 2010 To All RADIO AMATEURS BID: $ANS-010.05 A new Amateur Radio Satellite from India, named StudSat (STUDent SATellite) is slated for a March 2010 launch and will carry a camera capable of 90 metre resolution which will be used to perform the function of a remote sensing satellite and take images of earth's surface. The satellite resembles a small cube of size (10 cm x 10 cm x 13.5 cm), weighing about 850 gm and has a volume of 1.1 litres. The satellite is intended to be launched in 700 km Sun-synchronous orbit on an Indian launcher. StudSat plans to use a 10mW CW beacon on UHF and also a half duplex 9k6 or 4k8bps FSK TC/TLM link with 1 watt output also on UHF. This satellite has been coordinated by the IARU but the only frequency information available at this time states that 437 MHz will be used. Further information on StudSat can be found at http://www.teamstudsat.com/ The University of Colorado at Boulder has been awarded $840,000 from the National Science Foundation for students to build a tiny spacecraft to observe energetic particles in space that should give scientists a better understanding of solar flares and their interaction with Earth's atmosphere. Scheduled for launch in 2012, the three-year grant to CU-Boulder's Labor- atory for Atmospheric and Space Physics and the aerospace engineering sciences department involves the development of a 5-pound, loaf of bread- sized spacecraft carrying a miniature instrument package to observe ener- getic particles tied to "space weather" in the near-Earth environment. This satellite has been coordinated by the IARU but no specific frequency information is available at this time.

January 10, 2010 To All RADIO AMATEURS BID: $ANS-010.06 On January 8, 2010 Piraja, PS8RF worked Andre, ZS2BK via AO-7 (Mode B) in a footprint limit 34 second time window. The distance between the stations was 7694 Km. See the sound/video in youtube: http://www.youtube.com/watch?v=zNFmHERisWQ On AO-51 Piraja reports additional satellite DX with several contacts with Hugo, EA8HB on Las Palmas Island with strong signals. On January 6 Piraja heard the N1EL calling him, which is 5579 Km from him. On January 4 Bob, W7LRD copied 2E1EUB and MM5AJW on an AO-7 pass. Bob said it was the first time I heard anything other that Mika, OH8MBN. He invites European stations help him to stretch the AO-7 footprint. Mineo Wakita, JE9PEL reported FO-29 should come out of the eclipse soon. JARL continues to test the satellite and an operating schedule may be announced soon. Dave, KB1PVH noted this week that Perry, WB8OTH has now reached 6000 QSOs on the satellites. Nice job! SA-AMSAT says SumbandilaSat has reduced its power level to 2.5 watts to conserve power for other operations related to the primary mission. Initial reports from stations in Australia indicate that the reduction was hardly noticeable and that the signals remain stronger than most other amateur radio satellites. The SO-67 schedule is published on-line at http://www.amsatsa.org.za. The DX Newsletter DXNL 1657 - Jan 6, 2010 reported that XR9JA will be the callsign of Luis, XQ5CIE, Carlos, CE6UFF, Didier, F6DXE, and Dago- berto, CE5COX, from Jan 10-24 for their DXpedition to the Chilean naval base "Arturo Prat" on Greenwich Island belonging to the South Shetland Islands (AN-010). Operation will take place in CW, SSB, PSK31 on 160m-6m and via satellite on AO-51.

OT Tubes
by Steve 09 Jan '10

09 Jan '10

I noticed thread about building a tube amp, which reminded me I had a some lying around. I have dug them out and am offering them free to anyone who can make use of them. So I have 5 OA2 150 tubes (tube equivalent of a zener diode) and 5 2c39 tubes plus 1 cv6224 (conduction cooled 2c39 I think) they are all used or out of spec, but I believe they all work. They are free to a good home just pay the p&p and maybe make a donation to Amsat-UK for the funcube project. http://www.funcube.org.uk/ I used to work in a factory that made 2c39's and 4cx250's amongst other tubes, mostly Klystrons and TWT's and could often get hold of out of spec tubes etc. I wonder why I was a very popular Ham back in the 80's lol.

SatPC32 Releasing Ports
by Joel Black 09 Jan '10

09 Jan '10

I have an issue that appears to be with SatPC32 although I could be wrong. When I use SatPC32, all works fine with my USB-to-serial adapter controlling the radio. If I shut down SatPC32 and start HamRadioDeluxe, generally speaking, I cannot control HRD. It's as if the USB-to-serial adapter is still wanting to talk to SatPC32. Starting up SatPC32 in the same session works fine. I have found that a restart of the PC is not usually enough to release the USB adapter - a full shutdown is required. Occasionally, unplugging and replugging the USB adapter will work, but not often. USB adapter: U232-P9 PC: Dell E520 OS: Vista 32-bit RAM: 3GB SatPC32: v12.8a HRD: v5.0 build 2434 Beta When I was getting the version numbers, I started SatPC first and then HRD. Right now, it's working as it should. Even changing satellites, thus making the radio switch modes, doesn't cause HRD to fail on start-up. So, I cannot make it *not* work right now. Thanks, Joel, W4JBB

Happy New Year all This is probably simple, however, I need a quick and simple way of determining my uplink frequency given a specific downlink frequency. Usually I will just send a few dits to find myself. When trying to work a sked footprint edge to edge I need to be at the right frequency at the right time, without hunting around for myself.

Hello all, I posted a short video with the contact maintained today with Andre, ZS2BK via AO-7 in mode B ( Orbit 60848 - 19:47 UTC - 01/08/10 ). We keep the QSO with a small window that the AO-7 has provided us. The window was only about 34 sec, this time interval we could not match any commit error. The distance between the two stations is 4085 miles or 7669 Km. Andre wrote via email: " "My Doppler calc was also gratefully spot on. For example I calculated that I should call so that my downlink is on 145.944.2 mhz I worked out that our Doppler difference would be 3.8 khz and amazing that was spot-on. There is really no time to tune !" Andre is right the time was too little for adjustments. Taking also into account that I manually worked the rotor and control of my rig.

Doppler effect
by Daniel F6CDZ 09 Jan '10

09 Jan '10

Hello to all. My little contribution for an explanation about the doppler effect.... 73, Daniel F6CDZ loc: JN39BE Doppler effect The Doppler effect is an immediate gap of the received frequency when the distance varies between the point of broadcast and the point of reception. The variation of frequency depends on the relative speed of link or on estrangement between the satellite and the station ground, of the angle of movement and the emitted frequency. The Doppler effect varies with the position of the satellite on its orbit, because the relative speed varies with this position. The frequency increases when the satellite approaches, it decreases when it goes away from the observer. The "simple" formula is : F real = F nom (1 + V/C) V = relative speed of the sat on Km/s C = light speed (300.000 Km/s) 1+ or 1- depending of the direction sat/operator (to the operator or from the operator) Mode NORmal and REVerse : ¾ NOR : if I increase 1 KHz on VHF, the UHF increases also of 3 KHz => total gap (+1 + +3) = + 4 KHz ¾ INV(REV) : if I increase 1 KHz on VHF, the UHF decreases of 3 KHz => total gap (+1 - 3) = - 2 KHz

what did I hear?
by francesco messineo 09 Jan '10

09 Jan '10

Hi all, I'm just listening for a SO-67 pass and the satellite seems not operational at this time (8:40 UTC) but around 435.355 MHz +/- doppler I started hearing a kind of cw telemetry in short intervals. They are 6 letter "packets" or so, like ISUN44. I didn't copy other packets as I was busy trying to identify the satellite with the tracking program, but it must not be one of my "favourite" ones. What was I hearing? Thanks Frank IZ8DWF (currently in JM49MG).

The rate of change of Doppler is a sinusoidal function, so...

FW: AO-7 QSO 7694 Km

Sorry, the Correct distance the is 7694 Km 73 Piraja, PS8RF From: ps8rf(a)hotmail.com To: amsat-bb(a)amsat.org Subject: AO-7 QSO 7694 Km Date: Sat, 9 Jan 2010 02:14:07 +0300 Hello all, I posted a short video with the contact maintained today with Andre, ZS2BK via AO-7 in mode B ( Orbit 60848 - 19:47 UTC - 01/08/10 ). We keep the QSO with a small window that the AO-7 has provided us. The window was only about 34 sec, this time interval we could not match any commit error. The distance between the two stations is 4085 miles or 7669 Km. Andre wrote via email: " "My Doppler calc was also gratefully spot on. For example I calculated that I should call so that my downlink is on 145.944.2 mhz I worked out that our Doppler difference would be 3.8 khz and amazing that was spot-on. There is really no time to tune !" Andre is right the time was too little for adjustments. Taking also into account that I manually worked the rotor and control of my rig. See the sound/video in youtube: http://www.youtube.com/watch?v=zNFmHERisWQ I hope you enjoy it 73, Pirajá, PS8RF Quer ver seus e-mails de todas as contas num lugar só?

Hi all, Yes very pleased to hear the news and was about to post the information to the BBs. Many congratulations to Sir Martin Sweeting and his team at SSTL - a very just reward for all of the hard work and efforts by all involved. The news is also published in full on the SSTL web pages. Martin of course for anyone not aware is also Chairman of Amsat - UK and plays a key role in his support and contributions to the roles of amateur satellites and projects.

>> ... presentation and demonstration ... 01/10/10 ... hamradiouniversity.org ... OUTSTANDING, PETER! It has been great sending email messages back and forth with you last year. Then actually speaking with you on your VOIP net last week. NEXT: Actually meeting you! You'll do great at the hamvention. Just be yourself - you've got the right attitude and enthusiasm. Have a pad and paper handy for any Q&A inquiries that you cannot immediately answer for your audience: They'll appreciate the fact that you promise to get 'em the answers via email ASAP.
