Ahh, thank goodness for the engineers... Just know that to get started working the FM satellites, you do not need to spend much to make successful contacts...Working AO-51 from Southern California (which some claim is not a "real world") at a Watt or so with an HT and Arrow Antenna is a breeze, and the polarization of the Yagi makes no difference in quality of TX/RX signal. And as you refine your satellite comms requirements, you can spend more money! Clint Bradford, K6LCS 909-241-7666

Polarity questions

Hi, How much signal reduction is there as the result of having the wrong circular polarization? I'm looking at M2 circular antennas for the 70cm downlink, it's another $200 for the switching to change polarity (woo hoo). 73 de Tim, K4SHF

Hi , If they are the same Laptops that you are referring to they are now on sale over in the UK. They are notebook computers are produced by a company "HCL" and the operating system Windows XP. The UK distributor is a company that can be found at www,stirling house .co.uk 1520 London Road, Leigh on Sea, Essex SS9 2UR. They selling at a price of £179.99 ( UK) but of course carriage to the USA might put the price out of range. The package includes a Window XP CD and another with additional drivers, it does not have a CD or DVD built in so one would have to use an external device using the USB port.

GO32 APRS ?
by Henk, PA3GUO 18 Sep '08

18 Sep '08

Grrrr I seem to fail to understand the APRS mode of GO32: Kenwood TS2000X HamRadioDeluxe for auto doppler correction External TNC (PK96) hbaud 8600 u aprs via 4xtech uplink 145.850 in CONV mode: ":AP hello" ... some days ago this worked twice, then nothing got digipeated uplink 145.930 in CONV mode: ":2 hello" ... never any success Then: I see JA stations getting stuff like this over it: JA0CAW]APRS,4XTECH*,qAS,JH4BTI::JA5BLZ :GE ur599 TNXp whereas I would have expected somethin like "AP JA5BLZ ...." (AP in front) This is the only source of documentation I have: http://web.usna.navy.mil/~bruninga/GO32-ops.html Which states: 145.85 MHz All APRS messaging (or fixed station non-Mic-E positions). . Only TOCALLs that begin with "APxxxx". 145.93 MHz All APRS Mic-E positions and status(D7, D700 and D710s with comment set to "Committed, Special or PRIORITY"... The reason for these uplink distinctions is due to GO-32 hardware that will only digipeat a packet on 145.85 that has a TOCALL beginning with "A". (All APRS fixed station packets and all APRS messages including D7 and D700's) . The 145.93 channel will only accept packets that begin with a digit between 1,2,3,4,5,6,7. . But fortunately the D7 and D700's do this naturally as long as the position comment is set to "committed, SPecial or PRIORITY"... Q1: do the TOCALLs need APxxx or Axxx on 850 ? (in CONV mode type :APxxx ?) Q2: should here ":2xxx" work ? Thanks ! Henk, PA3GUO .... so lost :-)

BOD and President
by Bruce 18 Sep '08

18 Sep '08

The new president could wind up being a lame duck ... here is why. the board elects the president at the first board meeting of the new board. typically it is someone on the board. typically you are elected to the board and over your years of service on the board are groomed (so to speak) to be president. you learn the workings of the organization etc. there are 7 board members with voting capabilites. there is one alternate (cannot vote). if all board members are present for a vote, there should never be a tie unless one member abstains. now, let's say that someone not on the board (with voting rights) is elected president. he will only have a vote in order to decide a tie, thus never being able to offer a measure for vote, never being able to second a measure and never being able to vote on it. wouldn't that make the president ineffective and a lame duck? btw things are fun here in Houston/Harris county. my house is fine except no electricity or water so stating at my sons apt which has everything ( a benefit to living near the medical center ). I have worked a weeks worth of time in 3 days. the next 4 days will be for mucho overtime. hope andy and marty are okay have not heard from them. 73...bruce Sent from my iPhone

AO-16 update 9/16/2008
by Mark L. Hammond 16 Sep '08

16 Sep '08

Hello All, On 15 Sept 2008 at 10:58 UTC I commanded AO-16 ON and put it in voice mode. As of the time of this message (16 Sept 2008 at 17:10 UTC), AO-16 is still being reported as operational. That is over 30 hours of continuous uptime, which is a "good thing." Our predictions regarding sustained activities seem to be right on the mark. Recording your observations about AO-16 at http://oscar.dcarr.org/ has been, and will continue to be, very helpful to us. It is possible that the transmitter will turn OFF; this requires some commanding to get it running again, which means a pass over the Eastern US coast is required for a change in status. But we're hoping that the bird will remain ON more often than OFF for the next several weeks. Illumination projects (and subsequent temperature predictions) suggest that we might be able to sustain operations until early November. So, if you want some AO-16 contacts, you had better get them before then. After November 2008, it may be a long, long, time before the orbit provides favorable temperatures for the bird to remain operational for more than a few seconds or minutes at a time... Current operational mode for AO-16 Mode FM Voice Repeater ( Downlink is DSB) Uplink : 145.9200 MHz FM Downlink 437.0260 MHz SSB One behalf of the command team, -- Mark L. Hammond [N8MH]

15 Sep '08

> Should it be possible to launch two Leo > satellites...(satellite A) retransmitts > what it hears to the other Leo satellite > (Satellite B)... I think in that way i > could work NA every day? That is the intent of the APRS constellation of satellites. All operating packet on 145.825. We want to get as many of these satellties in orbit as we can to not only provide continuity of coveratge, but also dual-hop capabilities as you suggest. APRS can inherently, auomatically, work via dual hops, since it uses a generic path which does not need to be configured for each satellite callsign. That is also why the ISS moved to 145.825 a year or so ago, to be on the same channel, with PCSAT-1,PCSAT2,ANDE, RAFT, and others. There have been several instances of dual hop packets. The longest one recorded was from Africa over the Atlantic to Maryland. See: http://www.ew.usna.edu/~bruninga/pec/pc2ops.html Unfortunately, only ISS and PCSAT-1 remain in orbit and PCSAT-1 only works under some conditions, and ISS only works under others. But if you can find them both working at the same time, then dual hops are possible. You can watch the downlinks from these two birds and look for activity and dual hops just by looking through the on-line real-time downlink logs: www.ariss.net for the ISS http://pcsat.aprs.org for the others You can see that ISS has been off the air for 79 days except for a brief period 2 weeks ago. And PCSAT-1 (W3ADO-1) continues to limp along with some lucky packets during northern hemisphere mid-day passes. Ideally, if we can get 6 to 10 small APRS satellites on 145.825, we can provide near continuous message/email/status capabiliy from anywhere on Earth at any time. That is why I encourage all Universities making CUBESATS or other small satellites to include a 145.825 1200 baud packet link so their satellites can be used in this constellation after their primary mission is over.. Our next Satellite from the Naval Academy will actually be two-cubesats-at-once. Both on 145.825 with APRS transponders. Please, if anyone is working with other universities, see if they would consider this global constellation mission for their transponder... Bob, Wb4APR

Annual Report Discussion
by joe cassano aka jmario 15 Sep '08

15 Sep '08

AMSAT Members: There have been several recent postings on the topic of an AMSAT Annual Report. At the time of writing this (September 15, 2008) as near as I can determine the most recent annual report available to the membership is for the year 2006 (see http://www.amsat.org/amsat-new/AboutAmsat/documents/finance.php). On reading the AMSAT bylaws the closest thing I can find to a requirement for an annual report is in Section 1 which states: "An Annual Meeting of the corporation shall be held during October or November of each year at such time and place as the Board shall determine. At this meeting, the President shall present a report to the members." I believe the bylaws should be changed to incorporate the following: 1. assign responsibility for the production of an annual report to the the AMSAT President 2. specify a list of topics which must be addressed in the annual report 3. require no more than a 3 month interval between the close of the calendar year and the publication of the annual report 4. specify that publication must consist of mailing a copy to each member or posting a copy on the AMSAT website It might be appropriate to post the annual report on the AMSAT website and then later in the year distribute a printed copy of the annual report in the same mailing that is used to distribute BOD candidate's CVs and the BOD candidate ballot form. If you are a current AMSAT member your comments are solicited... Joe Cassano - K3FMA AMSAT member

DM31 trip postponed
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Sep '08

15 Sep '08

Hi all! I have received e-mails from a few operators that AO-27 was not operating during Sunday afternoon passes over North America. I also saw a note on the http://oscar.dcarr.org/ web site that shows a Japanese station did not hear AO-27 earlier today. Since this satellite was the one I was planning to use for my DM31 trip later today, and I don't want to make a long day-trip where there is a high probability that the satellite won't be operational, I am postponing this trip. I will not go out there today. I am looking to reschedule this trip for another time in the next few weeks, where I can spend more time out there and use other satellites instead of just AO-27. I will post details when I decide on a date for that trip. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Announcement from Matt Ettus: ======================================================================== USRP News and Announcements September 2008 ======================================================================== 1 USRP2 Now Available 2 Status of the original USRP 3 Daughterboard Status 4 Upcoming Events ======================================================================== 1 USRP2 Now Available We are very happy to be able to announce that the USRP2 is now available for purchase. The USRP2 builds on the success of the original USRP, and adds these new features: - Gigabit Ethernet interface - 25 MHz of instantaneous RF bandwidth - Xilinx Spartan 3-2000 FPGA - Dual 100 MHz 14-bit ADCs - Dual 400 MHz 16-bit DACs - 1 MB of high-speed SRAM - Locking to an external 10 MHz reference - 1 PPS (pulse per second) input - Configuration stored on standard SD cards - Standalone operation - The ability to lock multiple systems together for MIMO - Compatibility with all the same daughterboards as the original USRP At this time, the USRP2 is in "beta release" state. Not all of the software and/or features are currently ready for production use. The USRP2 is initially supported on Linux, and we anticipate that drivers for Windows, Mac OS X, and other systems will be developed in the coming months. We are currently offering the USRP2 for a special introductory price of $1400, which may change in early 2009. Due to the high initial demand, and the beta release status, we have made some modifications to the normal order fulfillment process: - You may order as many systems as you like, but we can only ship up to 2 units to each customer from the first batch. The remainder will be held as a back-order, and will be shipped when available. You can cancel the remainder at any time, if you wish. - Precedence will be given to longtime members of, and contributors to, the GNU Radio / USRP community. - There are no quantity, academic, distributor, reseller, or other discounts. We will not be selling to resellers for the time being, only directly. We apologize for any inconvenience this may cause, but we feel that this policy will ensure that we can get systems to the maximum number of users in the short term. The USRP2 package includes the USRP2 motherboard, an enclosure, 2 SMA-SMA Bulkhead cables for RF, an ethernet cable, power supply, SD memory card, and a hardware packet. The USRP2 is only available in this complete package configuration. Also available are extra ethernet cables, extra SD cards, and SD memory reader/writers for USB ports. The power supply is the same as the one used for the original USRP. For those wishing to use their USRP2s in a MIMO configuration, we are selling the USRP2 MIMO cable for $70 each. You only need 1 MIMO cable for every pair of USRP2s.

strategic plan, budget, etc.
by Robb Hill 15 Sep '08

15 Sep '08

Hi All, I read the last AMSAT journal and saw the very well written history of the Eagle project in the most recent issues of AMSAT Journal. The bit I felt was missing was the plans for the future including a plan, schedule, and budget. To that end I want to ask if anyone knows where one can access the strategic plan, budget, committee assignments, and annual report? Thanks, Robb

Annual Report
by Robb Hill 15 Sep '08

15 Sep '08

Hi, There should be an Annual report distributed to the membership in printed/online form like any other non-profit orgranization provides. It should list the financial status, membership status, operations, achievments, project status, regulatoryu status, etc. It should compare this to previous years. This is basic stuff for any non-profit or association. Can the board or president please let me know if this can happen? Thanks, Robb

elevation rotor
by Gerry 15 Sep '08

15 Sep '08

Thanks to all that replied to my request for help. Problem was in the rotor cable, about 22 inches from the rotor found cable jacket bruised (three of the six wires found to be broken). Cause unknown appears that the cable was compressed (squashed) and subsequent movement back and forth over a period of time finally broke wires inside jacket . Using a power supply in the shack and a test bulb at the rotor, we were puzzled, as to why using one wire as common, that three wires failed the test. It was just by chance that we found the damaged spot. The Rotor Gods were with us today hi hi. Thanks Again, Hope to be back up and running soon. 73 Gerry VE4GTB / KD7MDB

AO-51 mode L/S report 2008-09-14
by Rob Hardenberg PE1ITR 14 Sep '08

14 Sep '08

Hi all, Today I mounted a 67el 2.4GHz yagi antenna on S-band, installed my AO_40 equipment and used AO-51 mode L/S for the first time. It was great! I could make 3 qso's with EA3FXK, EA3EMG and OZ1MY. Also heard PA3GUO who has only a uplink tx. I noticed a lot of qsb between 51 and 59 independent on the uplink and/or downlink. So sometimes a strong downlink but no signal on the repeater. I could use the repeater to 4 degrees elevation on AOS and LOS. Also used no automatic doppler tuning. On the downlink tuned to the signal and switched on the AFC of the trx. The uplink was tuned by hand. equipment: L-band uplink: IC910 10w 26el yagi S-band downlink: IC910 + db6nt ao-40 converter + 67el yagi. I hope to see you on mode AO-51 L/S 73 Rob PE1ITR http://www.pe1itr.com

OK, what am I doing wrong with VO-52
by Mark Lunday, WD4ELG 14 Sep '08

14 Sep '08

Overhead pass, heard W9VNE calling CQ on CW, and QSO between him and a VE3. Sounded like he was almost in the middle of the downlink passband at 145.900 +/- for Doppler, so I put my transmit signal in the middle of the uplink passband (remembering that it is inverted, so the middle is a good place to be). I was transmitting on 435.250, callin several times but no response. I also heard some USB, but decided to stay with the CW and try to make contact. Kinda tough since I am using one FT817 and one Arrow antenna, but I should be able to get through. I did work through AO-7 last weekend, so I am not sure what I am doing wrong here. It is my first try on VO-52, but I was thrilled to at least hear the bird. Any thoughts/suggestions welcome. Mark Lunday WD4ELG wd4elg(a)arrl.net http://wd4elg.net

DM31 on AO-27, Monday 15 September
by Patrick STODDARD (WD9EWK/VA7EWK) 14 Sep '08

14 Sep '08

Hi! I am planning a quick road trip to a point near the Arizona/Mexico border tomorrow (Monday, 15 September). I will be in grid DM31 for at least the two AO-27 passes around 2046 and 2227 UTC, subject to local weather conditions and law enforcement (heavy police and Border Patrol presence in that area). I might stick around for an AO-51 pass Monday evening, around 0132 UTC, before making the 3-hour drive back to Phoenix. If there is a safe place to stop off the highway, I *might* be able to park on the DM31/DM32 grid boundary. Otherwise, it will be just DM31 for those passes. Grid DM31 is mostly in Mexico, except for the northeast corner of the grid that crosses into Arizona. A portion of a military bombing range, Organ Pipe Cactus National Monument, and the border town of Lukeville AZ in Pima County are in that corner. I've heard one station from that grid, on the Mexican side of the border, in June 2006 via AO-51. Others have told me it has been several years since other stations have tried the satellites from either side of the border in DM31. If we make a contact, I will send you a QSL. No worries! 73!

Double leo satellites
by Håkan Harrysson 14 Sep '08

14 Sep '08

Hello, I was just wondering. Should it be possible to launch two Leo satellites with transponders who are connected to eatch other? I am not sure i can explain exactly what i mean, but if we imagine one of them (satellite A) are heading my direction in a west pass and retransmitts that on the ordinary way and then also retransmitts what it hears to the other Leo satellite (Satellite B) who is in sight of satellite A but just more west then i am located. I think in that way i could work NA every day? It feels like with new SDR transponders and the problem to get satellites in higher orbits this could be a way to go? This is no HEO/LEO discussion, just some thinking that maybe have gone wrong HI! 73 de Hakan SM7WSJ Who is also pulling for P3E

September 14, 2008 To All RADIO AMATEURS BID: $ANS-258.01 AMSAT President Rick Hambly, W2GPS notified the AMSAT Board of Directors on Thursday, September 11 that he is not a candidate for President of AMSAT for the upcoming year. "After careful consideration, I have decided that I am not able to continue as AMSAT President beyond the next Board meeting and so I will not offer my name for consideration, and if nominated by others I will not accept the nomination for President. While I will be focusing most of my efforts on business activities, I will do my best to make the transition seamless", stated Rick in an e-mail to the current members of the AMSAT Board of Directors. Rick has served as President of AMSAT since October 2004. The current Board of Directors election concludes on Monday, September 15, when results of the balloting will be announced. Members of the new Board will then begin a formal search process to recruit and select a new President. This process is expected to take several weeks with the goal of having a new President identified prior to the AMSAT Board of Directors meeting on October 23, prior to the AMSAT Symposium in Atlanta. The search process starts immediately with an invitation to current AMSAT members (including BOD members, Senior Advisors, Officers, and the AMSAT general membership) to suggest current AMSAT members that they would recommend for consideration. Recommendations are requested by 1900 EDT Tuesday evening, September 16 to the AMSAT Corporate Secretary (Barry Baines, WD4ASW; e-mail: wd4asw(a)amsat.org). Names that are submitted will be initially reviewed by the BOD and those candidates that the Board would like to follow up with will be contacted concerning the interview/selection process. Rick Hambly, W2GPS will continue to fulfill his duties as President until the Board meeting in October. His current term on the Board of Directors expires in September 2009.

September 14, 2008 To All RADIO AMATEURS BID: $ANS-258.02 Mike, DK3WN said this week that a worldwide amateur radio effort saved the COMPASS cubesat. Mike reports receiving reports of good COMPASS beacons from Japan. The COMPASS cubesat has not reset over several eclipse periods and remains operational. The problem that depleted the batteries aboard COMPASS had its heater remain on constantly. Amateur radio stations around the world successfully transmitted the command to turn off the heater and allowed the batteries to recover. After the heater was turned off Mike wrote, "The only thing we can do is WAIT. Wait for longer sun periods and voltages over 3.47 Volts. That's the standard threshold value in emergency mode to switch into powersafe mode. Only in this mode we can change the threshold values. As of September 8, COMPASS was back in its powersafe mode of oper- ation. As of September 10 COMPASS was back in NORMAL mode. Mike had gained control of the satellite and could successfully command the satellite. Mike summarized, "Thanks to all - this is truly a worldwide ham radio effort - thanks so much for your help. Also, PLEASE do NOT send any commands to COMPASS until further notice. If you send any commands you overwrite the current settings and COMPASS may fall back into emergency mode. We almost lost a cubesat, but we've definitely gained some new friends. Thank you all for your efforts!" Meanwhile please listen to the beacon and keep your fingers crossed that COMPASS will remain in its normal mode.

Static Discharge Protection - location
by Alan 13 Sep '08

13 Sep '08

Where do you suggest mounting discharge units such as the Diamond CA-23RS - on the mast between the antenna and preamps? and grounded to the mast which is well grounded? - on the mast below the preamps and before the feedline enters your house/shack etc? - at the radio in the house or shack? - grounded to your service panel ground cable or grounded to the outside where your tower is grounded to something like I use - a copper rod driven 5 or 6 feet into moist salty soil. Knock on wood - I've never had an issue with static discharge that emanated from the antenna that has effected any radio or other equipment. Antennas and mast/tower are well grounded to earth outside my house and not to any inside cold water pipe. I ground my radio chassis ground lug to a copper cable run to my electrical panel's ground cable. All the 120 VAC is 3 wire and grounded to the same electrical panel grounding. I support there could be a potential between the service panel ground and the ground for my mast, but, I've never bothered to check this. I am slightly amused that these units are referred to by the various manufactures as lighting protection or surge suppressors. Lighting runs down the outside of a conductor. However, I can see an antenna building up a charge with wind or if my neighbour got a direct hit by lightning I house probably get some residual EMP. I suppose the discharge created by shuffling across a carpet in socks with low humidity and touching a wall switch could be call lighting of a few orders of magnitude less than what is commonly understood a lightning. Am I over thinking all this grounding and static discharge stuff and unnecessarily worrying about which ground to use. If I get a direct hit with lightning, all bets are off. Thanks all... 73, Alan VE4YZ EN19kw AMSAT LM 2352

Indeed, he was on one of the evening AO-51 passes. In addition, KL1WE & W6HF are also returning from Alaska to California; as well as AK, you can later look for YT and also uncommon-to-rare BC grid squares. So do not neglect Pacific passes on AO-51 and SO-50 for at least a week or so and also AO-27 (albeit in Alaska, one can't hit it before the telemetry if one is too far north). -- KD6PAG (Networking Old-Timer, Satellite QRPer) P.S. Remember, AO-51 is in mode J-FM on the 'QRP' side (435.15/145.88) this week.

SatPC32 Interface to Yaesu G 5400B
by Ralph Milnes 13 Sep '08

13 Sep '08

Hi, Re: SatPC32 Interface to Yaesu G 5400B New to the group... I tried to access the archives but there isn't an easy way to search them, so forgive me if this question has come up and been answered before. I'm helping a friend migrate to a new USB-only XP computer where he wants to run SatPC32 and interface it to a Yaesu 847 radio and a Yaesu G 5400B Az/El rotor. Our first problem is coming up with USB-to-serial converters that will work with the serial feeds to the radio and rotor. I tried one brand of converter and that didn't work. I know such converters are finicky, so I'll try another brand and hope that works. If I'm successful, that should solve the CAT control of the radio via SatPC32. But I'm not sure how to interface to the rotor. SatPC32 does not have a rotor control choice for the G 5400B. Has anyone solved this problem? Comments and suggestions welcome. 73 Ralph KC2RLM

FOxx Satellite DXpedition Results
by Mark Saurman 13 Sep '08

13 Sep '08

Hello all, I've made it back safe and sound from my little road trip. After my last contacts on the FN08/18 border near Amos, Quebec I put the Arrow back in the car for the last time and concentrated on driving. I went through Val-D'or, Mount Laurier, Mount Tremblant and finally Montreal where I picked my wife up from the airport the next day and we visited the city and Ottawa before heading back home. The trip was a lot of fun. I didn't haul out the gear until I hit FO11, although in hindsight I should have paid more attention and got out in FO10 on the way up since the passes weren't very viable in FO10 on the way back. These first contacts were made from along side the Rupert River rapids. They're endangered as Hydro Quebec is going to dam off the river for another huge hydro project so I'm glad I got to see them. Most contacts were made pulled alongside the Route de la Baie James, a 2 lane paved road with a 100km/h speed limit that isn't patrolled from about km 6 to km 600. The road is very isolated, with a 375km stretch with no gas stations or services of any kind. Some were made in the community of Radisson, the furthest north you can drive on a paved road in the eastern half of North America, and the northern most non-native permanent community in Quebec. Some were made in Chisasibi, on the shores of James Bay and some along Quebec route 109 which leads to the James Bay Road. I had hoped to catch a boat to one of the islands in the bay of which there are numerous, uninhabited ones very close, as these count as Nunavut VY0, however between the weather not cooperating (wind) and those who I came across weren't coming back to be able to pick me up, I had to scratch that plan. If I had more time to work with, I would have worked something out. More money could have helped, too, as I could have booked a flight for about $500 to Sanikiluaq in the Belcher Islands, which is comparatively cheap to what it costs to get to anything Nunavut from down here! Although for you newly married OM's, you and your XYL can go with a 75% honeymooner discount, so start sweet talking her about how nice the Belcher Islands are this time of year! HI HI!!! So here's the results: 5-Sept-2008 1815Z through 7-Sept-2008 1938Z Total Satellite QSOs: 158 - AO-51: 81 - AO-27: 36 - SO-50: 41 Grids worked from: FN08, FN18, FN19, FO03, FO10, FO11, FO12, FO13 Here's a link to the log: http://spreadsheets.google.com/pub?key=pVYahBbb9c8aa3JJuIwiAOQ Working conditions: Antenna: Arrow Handheld Yagi, 3-elements for 2 meters, 7-elements for 70cm Uplink Radio: Radio Shack HTX-202 at 3 watts with 6 2500mAH NiMH AA's in the alkaline pack, still charged even after 158 QSO's! Downlink Radio: Yaesu VX-7R still charged as well ;-) Logging done via voice recorder built into my cell phone, as that was about all it was good for up in the wilderness hundreds of miles from a cell signal! I'm printing the cards this weekend. Thank you all for the many QSO's and the cards & stamps I've received! Hope that everyone picked up at least one new grid. QSL is via my N8TLV address, although if you sent it to my NL address I'll still get it, just will be delayed by a month hi hi. 73, Mark VO1ONE/N8TLV

Re: DO-64
by WILLIAMS MICHAEL 13 Sep '08

13 Sep '08

Mark, Lately, I have not been able to get a signal through DO-64. I hear the beacon but no transponder activity. To check on DO-64, go to http://oscar.dcarr.org/index.php . I sent the Delfi team an email but got no response. I'll continue to try it when I'm in the shack and a pass occurs. When the transponder is on, activity is sparse. DO-64 is a challenge. My impressions of DO-64: Don't go spending a lot of money because of DO-64. When DO-64 was first released for amateur radio use, I was able the hear myself (CW) at very low elevation passes (<10 degs). My antennas are only 8 feet off the ground so I was shooting a signal through trees and buildings. When the sat got above 30 degrees, I was able to use the transponder for good CW QSOs. I think the transponder output is only 200mW. The circular polarity of the down link seems to be left hand in the north to south passes and right hand in the south to north passes. Since my down link antenna is LHCP, I can only work DO-64 in the morning ( north to south passes). The evening south to north RHCP passes across the US are currently not in the sun so the sat is off. I also notice down link signal strength is best on the first half of the pass then drops off in the last half. This makes it best to establish a QSO on the first half of the pass. The beacon always seems to be there and always at good signal strength. The transponder will have signal strength above the beacon at times when I have a good signal path at good elevations. At that point, I can reduce my 847s output to about 2 watts and still hear my down link pretty well. At this time, the transponder seems to be off. I will continue to try working DO-64. If I can help you any further, please email me. All the best in your satellite quests. Mike Williams K9QHO AMSAT 33589

AO-51 L/S mode
by Luc Leblanc 13 Sep '08

13 Sep '08

I just ending a near complete pass QSO with Michael KC9ELU on L/S. This western pass was much better than the east one?. Always manually tracking the uplink i found a way to control the doppler on the downlink using the AFC button on the PCR-1000 that i used to received the output of the AIDC downconverter on 123mhz. There is no need to have a PC tracking program just tune the downlink and let the AFC doing the job!! It works and if you loose the downlink for few minutes the AFC is quite agile and he will retune by himself right on the center of the downlink. You can always fine tune the frequency manually. The scope feature is also usefull if you drift too far away from the downlink you can see where the signal is without tuning up and down. I don't know if this will work for other type of receiver but the FT-847 does not have this feature? "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

SatPC32 Interface to Yaesu G 5400B - More
by Ralph Milnes 12 Sep '08

12 Sep '08

I forgot to mention that he's currently using the Unitrac interface to the G 5400. That's not supported by SatPC32. Any recommendations on an interface to use, preferably one with a direct USB connection (if such an animal exists). ---------------- Hi, Re: SatPC32 Interface to Yaesu G 5400B New to the group... I tried to access the archives but there isn't an easy way to search them, so forgive me if this question has come up and been answered before. I'm helping a friend migrate to a new USB-only XP computer where he wants to run SatPC32 and interface it to a Yaesu 847 radio and a Yaesu G 5400B Az/El rotor. Our first problem is coming up with USB-to-serial converters that will work with the serial feeds to the radio and rotor. I tried one brand of converter and that didn't work. I know such converters are finicky, so I'll try another brand and hope that works. If I'm successful, that should solve the CAT control of the radio via SatPC32. But I'm not sure how to interface to the rotor. SatPC32 does not have a rotor control choice for the G 5400B. Has anyone solved this problem? Comments and suggestions welcome. 73 Ralph KC2RLM

Re: p3e

Keith There was an update on P3E at the Amsat-UK Colloquium in July 2008. This was filmed and archived at www.batc.tv > film archive > Lecture 9. Lecture 10 gives an update on P5A. In a nutshell :- Amsat-DL are treating P5A as the primary mission, with P3E being a 'test bed' for P5A carrying some of the P5A communication systems, along with some rather useful transponders of course. The rationale being that P3E flies first to prove the various systems required for P5A, thus de-risking the latter. Amsat-DL are seeking funding for the combined P5A/P3E project. Full details in the presentations - recommended viewing. regards Grant G8UBN >Is there anything going on with p3e, or is it a fantasy to think we will ever have another Heo? >keith N6ORS

College Station Night Thursday Sept. 18
by Dr. Jay Garlitz 12 Sep '08

12 Sep '08

A college Satellite night will be held Thursday September 18, 2008 (local time). This event is a great opportunity for hams that are satellite active to interact with college students and elmer a new generation! Do you know a college student who would find amateur satellites interesting and intellectually challenging? Have them as a guest at your station and introduce them to amateur radio in a way they will never forget. Look for college stations and students on all the birds that evening and please give them preference for operation. With the new school year just starting, new student guests and thus potential young hams will be present in college shacks around the country. They look forward to meeting you through the exciting venue of Orbiting Satellites carrying Amateur Radio! 73, Hope to see you on the birds!

Uh, ISS, We Have a Problem...
by Clint Bradford 12 Sep '08

12 Sep '08

> How does Houston Control control the ISS when they have to close shop due to, say, a fierce, approaching hurricane? Well, it’s happening right now. Eleven laptop computers in a nearby hotel are controlling the ISS, since NASA's Johnson Space Center in Houston closed Thursday due to the approaching storm. The storm has also caused the delay of the docking of a Russian module scheduled for Friday. Russian flight controllers will execute a maneuver to place the spacecraft into a safe orbit away from the station until docking, which is now planned for Wednesday, September 17. If Johnson is not restored to full capability for docking, one of the backup facilities may be used to command station systems. Station Commander Sergei Volkov and Flight Engineers Oleg Kononenko and Greg Chamitoff are awaiting the arrival of the cargo ship, which is carrying more than 2 tons of supplies including a new shipment of food and fuel. http://web.me.com/clintbradford/Site/Blog/Blog.html Clint Bradford, K6LCS

NASA closes Johnson Space Center
by Rob Rousseau 12 Sep '08

12 Sep '08

Clint, Thanks for the heads up. That is pretty cool they can do all that from laptops from a hotel room no less. The (large-ish) company I work for has about 42% of their employees working working from home. I found a news article about NASA here: -Rob, KI4BKE http://www.chron.com/disp/story.mpl/metropolitan/5996566.html By MARK CARREAU Copyright 2008 Houston Chronicle Sept. 11, 2008, 6:55PM NASA closed the Johnson Space Center, including Mission Control, at midday as Hurricane Ike neared the Texas coast. The agency activated a temporary control center near Austin to watch over the international space station until the storm threat passes. As part of the storm precautions, NASA postponed the docking of a Russian Progress cargo capsule with the station, which had been scheduled for Friday, just after 4 p.m. CDT. The station's three-man crew includes American Greg Chamitoff, the science officer and two Russians, commander Sergei Volkov and flight engineer Oleg Kononenko. "We will assess any damage, and decide when it's safe to come back," said NASA spokesman Kelly Humphries as Johnson prepared to release its 16,500 workers, many of them residents of the communities around Galveston Bay. The temporary control center, set up in a hotel outside Austin, is equipped to communicate with the space station's crew around the clock through NASA's Marshall Space Flight Center in Huntsville, Ala. The space agency dispatched more flight controllers to Marshall, home to the station's payload operations center, which supervises scientific research aboard the orbital outpost. In an adjoining control center established as an emergency backup to Houston's Mission Control, NASA was prepared to take over long-term support of the station if the Johnson Space Center sustained severe damage from Ike. The Progress cargo capsule was launched from Kazakhstan on Wednesday with fuel, food, water, spare parts and other supplies for the 220-mile high orbital outpost.

AO51 mode: 23cm SSB up / 70cm FM down ?
by Henk, PA3GUO 11 Sep '08

11 Sep '08

Dear all, I was considering to submit the following mode to the AO51 command team. (I did this already a while ago but my emails seems to bounce) Objective: provide a means for stations with small ERP to test their 23cm uplink channel into AO51. Uplink 23cm SSB (!) Downlink 70cm FM (preferably 435.300) With 23cm FM uplink I seem not to have enough ERP to get over the sat. That is, I never made it through the squelch level of the AO51 receiver (using Kenwood TS2000X/10W, and a small cubicle quad antenna only). In SSB mode with the squelch open I could try even CW to see how weak my uplink is. Maybe just below squelch level, maybe far down in the noise. And: with SSB we can even have multiple stations testing their links at the same time ! Any thoughts of anyone else before I submit this request ?

AIDC 3731 problem?
by Doug Kuitula 10 Sep '08

10 Sep '08

Hi all, I've been trying to receive the 2.4 ghz from AO-51 using an AIDC-3731 downconverter with a grill. Any time I plug in the wall wart that came with the unit, I get S-9 noise on my receiver. The receiver is an Alinco DR-1200. I know it's not the best. But it's what I got. From the material I got with the downconverter, it needs 24 volts. Is that fixed in stone, or can I use something less for voltage? I think I'll try a couple of 12v batteries in series. Has anyone else had the same problem? Any suggestions will be appreciated. 73 and hope to make some more contacts on AO-51. de Doug KA8QCU

by Andrew Glasbrenner 09 Sep '08

09 Sep '08

I just wanted to report on the fine group the last few nights on L/S. Last night I heard/worked KC9ELU, VE3NPC, and N0JY, and tonight there was VE3NPC and N0JY again, and N8MH and KD8CAO. Signals are strong as always, although there was some buzz on the L band uplink that might be radar related. If you have L/S gear leftover from AO-40, c'mon up and join us this week on AO-51 L/S. Just make sure your CAT cable is hooked up, or your tuning finger is limber! 73, Drew KO4MA

COMPASS recovery efforts - THANKS !
by Mike Rupprecht 09 Sep '08

Hi all, I got a lot of beacons from many stations. Thank you so much for your support!!! The battery voltage is now around 4 volts. We will wait another day before we switch into NORMAL mode. ******************************************************** PLEASE do NOT send any commands to COMPASS until further notice ******************************************************** 00:42 UTC 85008007060700102949c600ff 3.88V (JA0CAW, JA1GDE) 00:47 UTC 60087021070000102949D00000 4.08V (JA6PL, JA0CAW, JA1GDE) 00:50 UTC 40009012020000102949c60000 3.88V (JA0CAW, JA1GDE) 01:55 UTC 29000000000000102949c21704 3.80V (W1ICW, KD8CAO) 01:59 UTC 48000000005000102949c10701 3.78V (W1ICW, KD8CAO) 02:03 UTC 82290018070000102949c00800 3.76V (W1ICW, KD8CAO) 02:23 UTC 83009000000400102949C600FF 3.88V (JA6PL) 02:27 UTC 90077200370400102949C800FF 3.92V (JA6PL) 03:32 UTC 29000100000000102949C31504 3.82V (KD8CAO) 03:36 UTC 29000000000000102949C21901 3.80V (KD8CAO) 03:39 UTC 70000200004100102949C50000 3.86V (KD8CAO) 07:12 UTC 95008000000000102949c800ff 3.92V (DK3WN) 08:45 UTC ff001800000700102949cc00ff 4.00V (DK3WN) 08:49 UTC ff000111090000102949c900f6 3.94V (DK3WN, M3RXX) 08:53 UTC ff002900000000102949c900ff 3.94 (DK3WN) 09:40 UTC 29000000000000102949C61608 3.88V (ZL2BX) 09:43 UTC 29000000000000102949C51607 3.86V (ZL2BX) 10:07 UTC 50000000003600102949c20701 3.80V (JA0CAW) 10:22 UTC 70007200400700102949c700f9 3.90V (DK3WN) 10:26 UTC aa057000301800102949d60000 4.20V (DK3WN) 10:29 UTC 90008820290700102949d100ff 4.10V (DK3WN) 11:12 UTC 29000000000000102949C71507 3.90V (ZL2BX) 11:16 UTC 29000000000000102949C71807 3.90V (ZL2BX) 11:20 UTC 29000000000000102949C71608 3.90V (ZL2BX) 11:35 UTC 29000000000000102949c51502 3.98V (JA0CAW, JA6PL, JA1GDE) 11:39 UTC 29000000000000102949c41805 3.84V (JA0CAW, JA6PL, JA1GDE) 11:43 UTC 59000000536000102949c40000 3.84V (JA0CAW, JA1GDE) 11:58 UTC 79050030700700102949cc00ff 4.00V (DK3WN) 12:02 UTC ee073500502800102949d400ff 4.16V (DK3WN) 13:07 UTC 29000100000000102949c51806 3.86V (Artur, Tainan) 13:17 UTC 29000000000000102949c51904 3.86V (JA0CAW) 13:21 UTC 56000000000000102949c41401 3.84V (JA0CAW) 13:43 UTC 50000050800000102949cc00ff 4.00V (W1ICW) 13:47 UTC d8070848430000102949d100ff 4.10V (W1ICW) 15:16 UTC 56071507830700102949cc00ff 4.00V (W1ICW) 15:20 UTC 81088007321800102949d50000 4.18V (W1ICW) 15:23 UTC 56027207501600102949cc00ff 4.00V (W1ICW) 16:51 UTC 4000a000180400102949cc0001 4.00V (W1ICW) 16:55 UTC 60008018070000102949cc00ff 4.00V (W1ICW) 18:10 UTC ................2949cc1704 4.00V (DK3WN) 18:14 UTC 79000000005000102949c90700 3.94V (DK3WN) 18:18 UTC 48120018150000103049cc0300 4.00V (DK3WN) I try to keep up to date my satblog.

If you are looking at the Celestial BBS then you have to load amateur.txt AND go to the bottom of the screen and load Cubesats. DO64 is in there or go to http://www.amsat.org/amsat/ftp/keps/current and download nasabare.txt. Keep in mind that AO-7 in that listing is listed as AO-07. In some programs this makes a difference but some don't. Perry WB8OTH pyantis(a)earthlink.net

LMR 400 Connectors.
by Tony.Corlett＠police.govt.nz 08 Sep '08

08 Sep '08

FYI: Telegartner make Male (Part # B3426) and Female (Part # B3026) Type N crimp connectors for LMR 400 cable. According our local Huber & Suhner agent and cable guru, these will crimp on to both LMR 400 Ultraflex stranded inner cable, and Suhner LMR 400 solid copper inner cable. The inner pins can be soldered on to copper coated solid aluminium inner LMR 400 cable such as Times Microwave. The bodies are nickel plated, and the inner pins are silver plated. Nickel is not reccommended for any professional / large radio site installations because of oxidation / intermod. problems. Suhner and Rosenberger both make slip fit connectors for solid inner LMR 400 cable. Stainless steel bodies with gold plated inner pins. Very high quality, and no special tools required; just a knife!

AO-16 update 8 SEPT 2008
by Mark L. Hammond 08 Sep '08

08 Sep '08

Hello All, As Drew KO4MA communicated recently, it appears that the recent reduction in eclipse/increase in illumination is having a favorable effect on AO-16 and its ability to sustain longer periods of voice operations. Our best theory is that a temperature sensitive hardware timer is responsible for the shutdowns. The current increased illumination periods are causing an increase in spacecraft temperatures (as observed from MBL telemetry). These increased temperatures appear to be favorable for the hardware timer and therefore for AO-16 operations. We are now seeing several hours of operation between transmitter shutdowns. We anticipate that things will improve further in the immediate days/weeks ahead. Current orbit predictions suggest that illumination will improve until mid-October , after which time the eclipses return---and with the eclipses come lower temperatures, and the hardware timer issue returns, shutting down the transmitters every few minutes or so. Sadly, AO-16's orbit is such that after this Sept/Oct/Nov period it will be many, many years before the orbit is again favorable. We encourage you to record your observations of AO-16 on this very useful and intuitive web site: http :// oscar . dcarr .org/ The Command Team uses this site regularly as a means of monitoring the status of AO-16 . It gives us a good idea on the length of time between shutdowns of the transmitter. We also use this site to "announce" that we've turned AO-16 back ON. Friendly advice--if you want to log some AO-16 voice contacts, you had better make them SOON! Mode FM Voice Repeater ( Downlink is DSB . Operation is Intermittent): Semi-Operational Uplink : 145.9200 MHz FM Downlink 437.0260 MHz SSB On behalf of the Command Team, -- Mark L. Hammond [ N8MH ]

ARISS Clarification--Please Read
by Frank H. Bauer 08 Sep '08

08 Sep '08

All, In the past 24 hours, two e-mail "Press Releases" were sent out by Miles Mann, WF1F, about ARISS related activities. Please ignore these e-mails as they are not totally accurate and Miles was given direction to not release this information. What was accurate is that the ARISS team has been working very closely with Richard Garriott, W5KWQ, his father Owen Garriott, W5LFL, the International Space agencies and Space Adventures on ARISS related activities for Richard's flight which is planned for mid-October. This includes several educational outreach contacts with the USA-based Challenger Centers, several other internationally based schools, some opportunities for general QSOs and, if the hardware is flown, an opportunity to receive some SSTV downlinks from Richard. However, the ARISS team is still working out the specifics on this initiative. We have not totally vetted these specifics through the ARISS international team. We have not completed coordination of our efforts with the requisite space agencies---RSA/Energia in Russia and NASA in the USA. And we have not completed coordination of our efforts with Space Adventures, who is working with the Russians to fly Richard on the Soyuz to ISS. I hope you can be patient with the ARISS team as we work this coordination out. We should be able to provide additional details in the next 14 days. And I hope you all get prepared for a lot of excitement this fall. Richard Garriott will fly almost 25 years after his father, Owen, W5LFL, made history as the first ham radio operator to communicate from a vehicle in space. And Mike Finke, who flies up with Richard, will take the helm as the ISS Expedition 18 Commander. Mike is a true ham radio enthusiast who plans to keep the ARISS microphone hot with lots of QSO excitement. On behalf of the ARISS international team I appreciate your patience on this and thank you all for your interest in the ARISS program. 73, Frank H. Bauer, KA3HDO AMSAT-NA V.P. for Human Spaceflight Programs ARISS International Chairman

AO-51 L/S MODE
by Luc Leblanc 08 Sep '08

08 Sep '08

Using the same S band converter that i was using with AO-40 i succeed to have some QSO on AO-51 VE2NPC and another station but i am not 100% sure of his callsign. First i think Squidly Diddly will be the type of operator best equipped to handle my station in L/S mode on a LEO sat. I am using my PCR- 1000 to have a graphical display of my up converter output on the scope display. Since my first attempt on L/S mode i found very hard to be on the right uplink frequency. This morning pass i heard Clare VE3NPC transmitting a couple of time to find the right uplink frequency on my side even adjusting as per the Orbitron doppler corrected uplink i was always out of the satellite L band receiver until i start to adjust my TX frequency lower and higher than the program displayed frequency. I ended up with a 15KC higher than the "supposed" doppler corrected frequency on Orbitron? Could be my upconverter is not properly aligned or the scope display on the PCR-1000 software is not too exact at 1.268GHZ? At the end i will have to set the satellite RX frequency 15KC up to be able to get in the RX pass band. Next step is to have my uplink frequency controlled by my PC as i need 2 additional arm here in the shack! Bottom line L/S is feasable and with some tweeking it can probably matched the V/S mode +- the obstacles and foliage blocking in the path.
