QSL information for Brock W6GMT
by Patrick STODDARD (WD9EWK/VA7EWK) 09 Apr '07

09 Apr '07

Hi! As some of you may know, Brock W6GMT recently was on the road, going from his home in southern California to his summer home in northern Minnesota. While traveling, he worked many stations on the satellites from the various grids he traveled through. Now he is in Minnesota for the next few months. If you would like to send Brock a QSL card, please do not use the address in California that is in QRZ.com and other databases while he is in Minnesota. Please use the following address: Brock Thomsen PO Box 222 Marcell MN 56657 Also, if you are QSLing W6GMT for those contacts while he was on the road, please write in the callsign box the grid that Brock was in for that contact. This will help him toward a "reverse VUCC" award, operating from at least 100 different grids via satellite. Thanks and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

SatPC32 tracks....
by Len N9IJ 09 Apr '07

09 Apr '07

I have used SatPC32 in demo mode in the past with no dificulties. After a short hiatus from sats I loaded things up today and find all of the sats WAY off when compared to on-line live tracks and Orbitron. All seem to be half the earth away from real-time tracks and I can not figure out why the error. I have updated keps both from within the program and manually though all files show the same creation dates. Suggestions? -- Len Revelle N9IJ "My career goal is to retire"

Re: RAFT transponder turned on yet?
by Bob Bruninga 09 Apr '07

09 Apr '07

> Do you have the Radar fence transponder turned on > this week? I will be in Texas this weekend and I > could listen for it if it's on. Dan, Thanks, The RAFT transponder needs to be activated by ground command when the satellite is approaching the radar fence. Problem is, we have found only one station in Texas, New Mexico, Arizona, Arkansas, Mississippi, Alabama or Georgia that has volunteered to help out. We have had some volunteers in other states, but they are too far from the radar fence beam. What we need are OSCAR class stations on 2m that are familiar with normal packet that can logon to the remote sysop function of RAFT's onboard KPC3+ TNC and send the command to turn on the Radar Transponder. It stays on for one minute and then fail-safe's to OFF. While the Radar Transponder is on, we get a Pure FM carrier that is also useful for hearing the "spin" of RAFT. We have several volunteers in Europe and they confirm that RAFT is no longer spinning, but since the Radar Fence is only over the USA, that part of the experiment is still un-tested. PE1ITR even built a 216.98 MHz beam and reports he can hear the 4 milliwatt RAFT radar transponder local oscillator. The way it is supposed to work, is a station in the Southern USA turns on the RAFT transponder about 30 seconds before passing through the fence beam. The 216.98 MHz receiver comes on and the 145.825 fm downlink comes up so we can hear anything the 216.98 receiver hears. When it passes through the fence, everyone in the footprint should hear the 1 second or so radar beam as a Doppler tone. >From The tone tells us the angle of passage through the beam, the time tells us when it crossed the beam. From thos two, we can tell whre it is. So, still looking for more volunteer 2m stations with beams familiiar with tracking satellites, familiar with operating packet, familiar with the KPC3 remote-sysop function, that live in those southern states from Arizona to Georgia.

Hamsat 2nd birthday
by Prathap Kumar 09 Apr '07

09 Apr '07

Hi All Hamsat will be be celebrating its 2nd birthday on 5 May, completing 2 years of healthy & successful operation rendered to Hams worldwide. ISRO and Amsatindia plan to celebrate event with one day seminar planned during the week May 7-11. One day programme 9AM - 3 PM. No Fee but Registration is a MUST. Tentative programmes have been discussed a) ISTRAC report of the Hamsat b) User reports and experiences. c) To promote new comers on easy satellite operation. Display, demo and talk on the equipments required for easy operation of satellite. d) Proposal for the Hamsat 2 , with higher orbit and innovative features. We shall be announcing the final programme soon. Anyone willing to present a talk or demo , display should sent complete details of the talk or demo etc , before 21 April 2007 However we request those willing to attend the seminar to confirm by email with complete address, tel / mob nos, email ids etc. Please note that due to security reasons all registrations should be complete and received before 30 April. I know last year most the DX hams were interested too , but this time I think there maybe little time for them to prepare their travel, however DX hams in VU around that time can reschedule to attend the seminar. DX hams attending should send scanned copy of their passport. ( subject to security clearance by ISRO ) DX and VU hams hams can also send their reports and experiences to reports(a)amsat.in which have been forwarded to the Hamsat Project director and Mission management team. You are welcome to join our discussion group amsatindia(a)yahoogroups.com by sending in your ham profile. So looking forward to the Hamsat 2nd birthday & great eyeball.

portable questions
by Steve Attfield 09 Apr '07

I have a few questions for the group about a portale setup I'm orking on. I intend to use it for both linear transponder and FM satellites. the setup will consist of yagis for V and U mounted on a camera tripod with a short run 5-6 feet of coax to the radios. the first thing i'd like to know is: is it worth it to put something like lmr 400 ultraflex or will rg 213 work well. also would it be benificial to have a preamp to mount on the feedpoint of the downlink antenna? -Steve VA3SAX

LVB Tracker users in the US
by Gould Smith 09 Apr '07

09 Apr '07

I built a LVB tracker board and am using it with SatPC32 and it is works quite well. I assembled mine from parts I had on hand and then ordered parts from Digikey and Mouser. There is a chance that we might offer the bare boards at the AMSAT booth during Dayton. I need to also have a US parts list available. I am looking for someone or ones that would work together and assemble a parts list with part numbers for Digikey, Mouser or Jameco as the supplier. One supplier would be good, more than one would be great. Any volunteers? Obviously I need this in the next 3 weeks. Thanks, Gould, WA4SXM Director Field Operations

Wayne W9AE replies: Don't use the "tuner" portion of your KCT/T. Just connect a null-modem serial cable between the FT-847 and a serial port on your computer. Then go in the SatPC32 Setup -> Radio menu and specify the port number, radio model, and baud rate. Be sure to specify a matching baud rate in the FT-847's menu #37. 57600 baud is best. The FT-847 requires a "null modem" serial cable that swaps pins 2 and 3. I don't know why Yaesu didn't wire the CAT connector to use a straight-through serial cable.

DSP satellite detection on 10m?
by Robert Bruninga 07 Apr '07

07 Apr '07

MARScom downlink: 27.9625 MHz USB If anyone wants to try their DSP prowess at detecting the 1200 baud AX.25 downlink from MARScom on 27.9625 MHz USB dial frequency, there is a great opportunity. MARScom only has till mid July before it de-orbits. We suspect the 4 foot HF wire did not deploy, and so no one has heard it. But then no one with big ears and DSP prowess has reported attempting to do so. It beacons a 1 sec packet once a minute. Just thought I'd post the challenge. MARScom is coming over in the evenings in the Northern Hemisphere. Its packet uplink is 148.975 FM and it should digipeat on demand via the UNPROTO APRS VIA ARISS path for any MARS stations that authorized to transmit on that freq. Tracking it with a good 10m beam would sure help. Thanks Bob, WB4APR US Naval Academy Satellite Lab

I must have really messed up entering keps ( I guess copy /cut /paste doesn't alwasy work!) I re-entered keps and now seem to be just fine with 07 for 2007. I also replaced the AA battery holder as the batteries in the unit were corroded and the back up memory wasn't holding anything. One last comment, thanks to all who replied, I appreciate the advice. I also noticed that the range on the Sat Trak IV is in kilometers, not miles. I don't see a way to change that, but I really don't care at this point. Its right on with other tracking programs. VO-52, AO-51 and FO-29 here I come!!!

RAFT and ANDE operational
by Robert Bruninga 06 Apr '07

06 Apr '07

RAFT and ANDE are now coming over in the prime eveining hours. In fact, if you look at RAFT you will see it is nearly sun synchronous, in that it is coming over nearly the same time every evening. That is about 7:45, 9:15 and 10:45 PM local sun daylight time at mid (40 deg) N latitudes. PA3GUO reloaded RAFT settings and the packet-to-voice synthesizer is enabled. Anyone can turn it on, and then anyone can send APRS messages to "TALK" and it will speak the message. See how on the page below: http://www.ew.usna.edu/~bruninga/ande-raft-ops.html Also, we need stations with good beams in the southern USA states from AZ to Georgia as volunteer command stations so that we can check out RAFT's radar receiver too. RAFT is halfway through its life and will de-orbit by late July. Also, RAFT is only useable in the dark, so we don't have many more operating periods to operate this unique transponder. Also, if anyone has lots of power on 10 meters and will use it to TX CW, we would llike to activate the PSK-31 transponder and try again at hearing some signals. WB4APR, Bob

Flex-5000
by Robert McGwier 06 Apr '07

06 Apr '07

An announcement of a new radio was made by Flex Radio today. It is a completely full duplex radio. With transverter, it will be a wonderful satellite radio. No sound cards, etc. will be required. Again, it is completely full duplex. FlexRadio Systems New FLEX-5000(TM) Software Defined Radio Product Line FlexRadio Systems introduces the FLEX-5000 line of open source Software Defined Radio (SDR) transceivers. The FLEX-5000 family follows the very popular SDR-1000(TM), and now integrates all sound card functions and control over a single FireWire (IEEE-1394) cable connection to a user provided computer. A separate sound card is not required. There are two additional versions of the FLEX-5000 (models C and D) that provide higher levels of integration. The FLEX-5000C(TM) model has a built in Intel Core2 Duo processor and comes with the Microsoft Windows XP operating system, wireless keyboard and mouse. The FLEX-5000D(TM) includes everything above and adds a 9" LCD display with touch screen and large tuning knob. For more information and pricing on the FLEX-5000, please see the copy of our ad linked below: http://support.flex-radio.com/Downloads.aspx?id=148 You may also click on the "Contact Us" link on our home page at www.flex-radio.com. Frequently Asked Questions How do I place an order? A. We will begin taking orders for the FLEX-5000 (base model) and the FLEX-5000C on or before Monday, April 9th. Orders can be placed on our website at http://www.flex-radio.com or by phone/fax (see the Contact Us link on our webpage footer). Note that all online orders are prepaid (balance is charged immediately). When will I get my FLEX-5000? A. We expect to begin delivery of the base model on or before the end of June, the C-model on or before the end of Q3, and the D-model on or before the end of Q4. Pre-paid orders will be shipped first followed by unpaid advanced orders in the order that they are received. How can I ensure that I get one quickly? A. Order now and pre-pay. Pre-paid orders will be shipped first followed by unpaid advanced orders in the order that they are received. Will the SDR-1000 still be available? A. We have a limited inventory of SDR-1000s available. The SDR-1000 continues to be a high performance / low cost transceiver. The PowerSDR(TM) software will continue to support the SDR-1000 and will continue to receive new features and performance enhancements over time. Many improvements to the software developed in correlation with new hardware, such as the recent improvement in TR transition time and accurate power control from 1-100W, will apply to the SDR-1000. How long can I expect FlexRadio Systems to support the SDR-1000? A. We plan to support the SDR-1000 far into the foreseeable future. Can I use an external sound card with the FLEX-5000? A. No. The built-in "soundcard" is the equivalent of a comparable $1000 pro-audio card. Will there be a low power or receive-only version of the FLEX-5000? A. We are considering coming out with such models sometime in the future. What happened to the SDR-XT? A. The SDR-X project is alive and well. The goal of the SDR-X project is to build a supremely high performance multi-channel receiver. The target market has shifted to commercial and government applications. The work on the SDR-X resulted in the development of the FLEX-5000 family. We recognize that the introduction of the FLEX-5000 will continue to raise questions. We will post these and other popular questions on the FLEX-5000 FAQ page on our website (coming soon). The SDR-1000 set new performance standards for radio communications. The Flex-5000 will continue to raise the bar. Thank you for your support. Gerald Youngblood, K5SDR President FlexRadio Systems -- AMSAT Director and VP Engineering.

Lots of XE stations on AO-51 this morning!
by Patrick STODDARD (WD9EWK/VA7EWK) 06 Apr '07

06 Apr '07

Hi! As I mentioned in an earlier post, I thought I heard more XE stations on AO-51's 1513-1527 UTC pass than on any other pass in the past year or so. I just completed my logging from my recording of the pass, and I heard 10 different XE calls: XE1HON (Michoacan, DL80) XE1KW (Colima, DK89) XE2AT XE2BHL (Tijuana, DM12) XE2JTS (Chihuahua, DL68) XE2PHH XE2PWF (Sinaloa, DL55) XE2YBG (EL13) XE2YWB (DL83) XE3ISS (Cancun, EL61) Fernando XE3ISS was also on an SO-50 pass at 1450-1500 UTC, just before the busy AO-51 pass. Stations from all over Mexico, all 3 mainland call areas, as well as a good assortment of stations from across the continental USA. Hopefully XE2YW and XE2HWB show up from some other grids as had been reported earlier this week, which would make me (and my logbook) happy. After just over 15 months of working the satellites, my satellite logbook is now up to 2101 QSOs. And I'm still having fun! Have a great weekend, and 73!

Kiron Sat Trak IV
by mi magic 06 Apr '07

06 Apr '07

Hello! I have a Kiron Sat Trak IV and am wondering if this device is working properly. I enter in Keps and set the date and time, but the year is only available to be entered as a 2 digit year, 2007 is 07. I was using STS-PLUS for comparison and nothing seems to be in sync between the two tracking programs. Is it possible to "fake" out the Sat Trak IV with a different year? I'm guessing no. Any help would be greatly appreciated, I am just about ready to put up a complete tracking setup with AZ/EL rotators and I am really hoping I can use this box.

CW sound in background?
by Luc Leblanc 04 Apr '07

04 Apr '07

On an Irish TV car advertisement you can hear CW or kind of code but not morse code. Some report it is code as it existed just before morse code was created. It is a weak tone in the background just listen carefully what i can copy is CQ CQ CQ D only the letter D don't know what this D mean? The rest is gribbish code. Put your tone setting to eliminate bass and set the high to max and your volume up to the point the background tones start to distort. Some cheap PC speakers are unable to reproduce the tones. http://www.youtube.com/watch?v=Z_JcR9yqLh8 "-" "It is not the class of license the amateur holds, but the class of the amateur that holds the license."

Question VE and Dayton
by William Leijenaar 03 Apr '07

03 Apr '07

Hi AMSATs, Recently I read on the AMSAT website about Dayton and the AMSAT/TAPR Banquet etc etc... As I never been to the Dayton Hamvention I like to have an idea if there will be many AMSATs to meet, or that it is more a general ham event with lot of stuff to buy/sell ? As I can not easy buy/sell (heavy lugage/custom problems) I am more interrested in meeting AMSAT hams across the big ocean. Because Canada is also on my list of countries to visit I have a plan to fly first to Toronto a few days before Dayton, and have a look at Niagara fals etc. However, Dayton is not a short ride, and I like to know if some VE/US hams can tell me if its an easy way to get to Dayton from VE ?? (any Bus ? how long travel ?) I have experience with travelling and will not easy get lost... however, your information will help me speed up to find my way :o) PS: Maybe there are VE (AMSATs) going to Dayton ? 73 de PE1RAH William Leijenaar AMSAT-NA (36370) --- ____________________________________________________________________________________ The fish are biting.

SO-50 demo from W5ZU, Roswell NM (DM73), 6 April
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Apr '07

03 Apr '07

Hi! Steven K9TVS will be doing a demonstration on the SO-50 satellite Thursday evening (Friday, 6 April, UTC time) on the 0036-0049 UTC pass for the Pecos Valley Amateur Radio Club in Roswell, New Mexico. Roswell is in grid DM73, and the demo will be done using the club's call W5ZU. This pass will cover most of North America, and Steven would appreciate calls during this pass to show the coverage of an amateur satellite. K9TVS has been showing up on various FM satellite passes with very good signals over the past few days, so give Steven a call if you hear him on before the demo later this week. 73!

"Gary Mayfield" <gary_mayfield(a)hotmail.com> wrote: >I believe AMSAT still has program to generate keps for the moon at > >http://www.amsat.org/amsat/ftpsoft.html#pc-eme The AMSAT web site calls these pseudo-Keps, because the NORAD orbital models just don't apply to the Earth-Moon system. Among other things, the Moon's mass is far larger than any satellite, and its orbit is affected by the Sun far more than any satellite the NORAD models are intended to track. And now for something completely different: I recently bought Connections on DVD, and in one episode James Burke started with a wonder of modern technology, a satellite navigation system. It appeared to be a Transit receiver (no GPS in 1978), and was quite the contraption: two big boxes, one little one, a wild looking VHF/UHF antenna and lots of cables. The Transit satellites are still up there, but they don't use them for navigation any more. Laura Halliday VE7LDH "Que les nuages soient notre Grid: CN89mg pied a terre..."

Dual Hop
by Sil - ZL2CIA 03 Apr '07

03 Apr '07

Hi, I few days ago now, ANDE-1 and RAFT were simultaneously visible from my QTH, and everyone else's too, I imagine. Since both satellites Tx and Rx on 145.825 MHz, I wondered whether a dual hop is possible. However, it seems that the satellites are configured to prevent this. I wonder if there are any plans to try a dual hop - perhaps later when the satellites are near the end of their lives. I presume too, that when they are in sight of each other, RAFT would been keeping ANDE awake. Is this true? Sil - ZL2CIA

OSCAR-11 Last chance to hear for a while.
by Clive Wallis 02 Apr '07

02 Apr '07

Hi, OSCAR-11 switched ON early 01 April, as expected. Good steady signals on 145.826 MHz. This is the last ten day operational period before eclipses start on 20 April. The eclipses continue until 23 August. If the satellite behaves as it did last year, it is unlikely to be heard for any length of time, during the eclipse period. Enjoy! 73 Clive G3CWV Hitchin, North Hertfordshire, UK.

AO-51 Field Day Mode L/U and V/U dual repeaters
by Andrew Glasbrenner 30 Mar '07

30 Mar '07

For Field Day this year AO-51 will be in a dual repeater mode, with the following frequencies: L/U repeater Uplink 1268.700 FM, no PL tone Downlink 435.150 FM V/U repeater Uplink 145.920 FM, no PL tone Downlink 435.300 FM As a reminder, both the AMSAT and now ARRL Field Day rules state only one completed QSO per FM repeater satellite. Please adhere to this rule so that others may have an opportunity to make a QSO. Also, all stations are asked to please only transmit when they can hear the satellite, and please use full duplex (with headphones) as a courtesy to the other users. Those stations planning on using circularly polarized antennas please remember the 435.150 downlink is left hand circular polarization (LHCP), and the 435.300 downlink is right hand circular polarization (RHCP). Stay tuned to AMSAT ANS bulletins or the AO-51 News page http://www.amsat.org/amsat-new/echo/ControlTeam.php for practice sessions of this mode to be scheduled several times between now and Field Day. 73 and Good Luck!

TNC settings for Kenwood TM-D700
by Jordan Woolley 29 Mar '07

29 Mar '07

Hi all, Was just wondering if there is anyone out there with any experience setting up a D700 for Packet operation. I do not seem to be able to get my terminal program to speak to the TNC. I can't even get a cmd prompt or any semblance of a connection. It seems to be physically connected fine but still no luck. I have set the baud rate for the port to match the TNC (9600) but am not having any luck. I am just using HyperTerminal. Any ideas? Thanks Jordan VK2HCA

An Alien Pentagon base found on Saturn
by Luc Leblanc 28 Mar '07

28 Mar '07

Amazing discovery Probably an Alien Pentagon called an Hexagon for the aliens has been found on Saturn. It seems this structure is made of gas quite different than the solid Pentagon made of solid materrial but also full of hot air gas. The Aliens are probably like ghost made of thin air or gas or made of jelly or slime. There is no information reported at this state about any military use of this structure but there is a strong possibility that no military use was involved. As this hexagon is a more balance structure than the Pentagon we cannot excluded any peaceful Alien use. If an Alien chief in charge exist he's probably made of hot air too or made in a hollow shape containing probably the same compress hot air or gas. The only one way he can live and be supported and survive in this harsh environment. http://www.nasa.gov/mission_pages/cassini/multimedia/pia09187.html "-" "If something can be possible someone probably invented it " Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

What can I do with just 2 meter FM equipment??
by Michael Tondee 28 Mar '07

28 Mar '07

Unfortunately because of some financial issues, I'm going to have to sell my TS-2000X. I've avoided it and tried to figure some way around it but the sad reality is that it's got to go. I was thinking that I'd be leaving the satellite game for awhile but then it occured to me that maybe I could do something with 2 meter FM. I have a Kenwood TM-241 mobile rig and a Yaesu Ft11R handheld. Isn't APRS done on just the two meter band? Would it take both radios or just one? Are their other things I could do like possibly monitoring beacons or decoding telemetry and such. I have no TNC but I could use AGWPE with my soundcard. I'd just like something to "scratch the itch" so to speak till I can go back to a more fully equipped station. Thanks, Michael, W4HIJ P.S. If I owe any of you QSL cards, please be patient, I am getting to them!

Re: P3E transponder and launch
by William Leijenaar 27 Mar '07

27 Mar '07

Hi AMSATs, I am supprized to see that my mode-uv work for the P3e is still remembered :o) I wonder what happened with the mode-uv transponders designed by the other (New ealand, Russian, German and ??) groups ? Lately I only read about the SDX work of NA, UK and DL, but what about the other parts made by other (none NA,UK,DL) hams ? >From the messages I feel that the SDX seems to be the best radio at all, with a larger dynamic range, better aligator killer, better HELAPS etc... SDR technology is very interresting and it should be explored, but somehow I feel that only its advantages are named. So I like to "flip the count" to its other side to have "the pair of scales in balance". About the dynamic range, I wonder how it can be better than an analog receiver. I suppose the RX side (UHF) will not directly be digitalized (it would need an high speed and high power ADC) so there is still an analogue amplifier and down-mixer needed in front. Then there is only the IF part where it can be dynamically be better. I guess with analogue electronics this can also be done :o) I also seen someone mentioned about 1970 electronics, as if todays electronics is only better in IC form. Todays 2007 transistors are much better than in 1970, they are much smaller, and have a better performance. Even analogue style transponders can be made better and smaller size than those in Ao-10, with todays transistors. Have a look at my modern analogue transponder system at: http://www.observations.biz When talking about old technology then HELAPS (or officially called EE&R) is even more older, from 1952 ;o) That the HELAPS works better only due to the "modern" SDR system is not compairing in a fair way. Then you compair 2007 SDR electronics with 1975 transistor electronics. I believe with todays modern discrete electronics the HELAPS system will work equally or even better. The SDR system with zero-IF is a nice system which is very flexible. However zero-IF can have problems with DC-drift over time what gives unefficient ADC use or even ADC clipping. It is also more sensitive for low frequency 1/f noise, and the high frequency digital processing signals are a serious threat on sensitive receiver inputs... (also a problems in modern cell-phone systems) A Near-Zero-IF system might be a solution but is more complex to integrate. The filters at such low frequencies (zero-IF) can be made very sharp, but the same trick can be done in analogue way, with an RC low pass filter :o) Several years ago I present such a bread-bord system as "Quadrature transponder" where I could easily change the transponders bandwidth and change from inverted to none-inverted :o) The difference is that it takes far less power than a DSP does, and it was extreemly KISS... I agree that digital DSPs are more flexible which is good when you like to use the same radio for other modes also. This was my vote for the analog transponder systems :o) I hope the digital SDX works well and hope that its analog sister will also have a chance to do its work and gets its technical respect... 73 de William --- ____________________________________________________________________________________ Be a PS3 game guru.

Pre-amp for IC-910h?
by m0ady＠m0ady.org.uk 27 Mar '07

27 Mar '07

Hi... I am thinking of buying a masthead pre-amp for use with the Icom IC-910H for both satellite and terrestrial work. There are the AG-25/35 units from Icom which are specially designed for use with the 910. But I have seen the SSB Electronics units on the web (SSB-SP-2000/7000) and also the Microset units (PR-145A/430A) and wonder if these devices perform better than the Icom units. Also, would the SSB/Microset units require a sequencer. I would be interested to hear from anyone who has been down this road with an IC-910H. Thanks in advance, 73 Martin M0ADY. -- Martin Grundy (M0ADY) <m0ady(a)m0ady.org.uk> AMSAT-UK: 6314

RAFT packet satellite assistance needed
by Robert Bruninga 27 Mar '07

27 Mar '07

RAFT's packet-to-voice circuit only works in the dark, and in a few days, RAFT will begin entering the late evening time frame when Northern Hemisphere stations can again use it. RAFT is nearing its mission life time half-way point. It has decayed down to 180 nm and will re-enter before the middle of August. Due to its low orbit and small footprint, we need command stations in the Southern USA between Arizona to Georgia to help us conduct our primary mission of detecting the 218.98 MHz radar fence when it flies through it. We need command stations in those states because they are near the radar fence and will be in the footprint of the radar. The ideal command station has these atributes: 1) A reasonable 2m beam for ops on 145.825 2) A packet TNC 3) A familiarity with dumb-terminal TNC operations such as A. Connections, Converse, UNPROTO, etc B. Remote sysop logon of Kantronics TNC's 4) Desireable, is some experience with UI packets and APRS The objective of these southern command stations is to logon, send the command to activate the RAFT Radar receiver for 1 minute in anticipation of passing through the fence. Then hopefully recording any audio heard on the downlink (145.825). Of course, once the radar receiver is on, everyone in the footprint should be able to hear it. For info, see the ANDE-RAFT operations page: http://eng.usna.navy.mil/~bruninga/ande-raft-ops.html And for more info on the 216.98 MHz radar receiver, follow the links to the RAFT design pages. If you meet the criterial above, lemme know. Bob, WB4APR. US Naval Academy Satellite Lab

P3E transponder and launch
by Patrick McGrane 26 Mar '07

Greetings from pat n2oeq I have been looking forward to the launch of P3E which I thought was going to be this year. I am concerned about the germans use of the SDR technology over william Liejanier's transponder design. I am of the belief that signal processing presents a loss in the path, please correct me if I'm wrong. Williams Hamsat transponder is excellant and made me very interested in P3E. Besides making the voice unnatural, are other modes allowed through the SDR transponder? Does the Helaps system compensate for the loss? I'm of the Keep it simple discipline as once its up there nothing can be done to fix it. If amsat-dl is monitoring , please update your website and provide a direct Paypal donation utility.

Help with MixW2 getting AO-51 TLM
by Edward Cole 26 Mar '07

26 Mar '07

Hi, I have upgraded my MixW2 (demo) to vers 2.18 and going over settings to receive 9600 bps FM AX.25 telemetry from AO-51. I doing this in hopes to get a good test before trying to receive CAPE-1 after launch March 27. Long time ago I had it working with virtual connection with tlmEcho program, but I am just wanting to recover raw telemetry for CAPE-1 since no decoding sw is available for CAPE-1 to my knowledge. I tried capturing some on the last pass which was north of me, but I had the wrong frequency for most of the pass. Still tuning near 435.150 toward the end of the pass I could not detect any signal (quieting) from the 9600 packet signal. I know that 9600 does not provide sound that is heard but I recall that it should provide some quieting in the passband. I wonder if anyone is using MixW2 with tlmEcho to recover AO-51 tlm? I sure would appreciate having someone check my sw settings for MixW2. There is no local source of 9600 packet to use for checkout. I am stumped why MixW2 comes up with a window stating my demo period has expired as I just downloaded it yesterday (supposed to get 15-day free demo period). Will this kill any chance of retrieving data?

OZ7IGY beacon over FO-29 for 50 year aniversary this week
by OZ1MY 25 Mar '07

25 Mar '07

Hi all, The old vintage OZ7IGY (International Geographic Year) beacon has been activated on approximately 145.988 MHz. They wanted to use another frequency, but had problems so that they asked me if it was OK to use 145.988 MHz. That is is nice frequency since OZ7IGY is retransmitted by FO-29 in the low end of the downlink band. That end is not used by anyone normally, so it should not be a problem. It will be for this week only. It is not on all the time since it is very old valve (tube)equipment. I think the plan is to use it most af the day during the weekend - and 16 - 22 during working days. The signal from FO-29 is really good when the elevation angle from JO55 (Denmark) is low. I could hear it from FO-29 at a distance of 4100 km from my QTH. The beacon OZ7IGY is probably the oldest VHF beacon in the World ? Try to listen for it - this is a one time event ! Stations in Europe may want to have QSO with OZ7IGY, which is manned this weekend and from 16 to 22 during the comming week. I have heard it on 432.270 MHz. They use the beacon antennas and 25 W only. Have a nice weekend 73 OZ1MY Ib

Re: CubeSat launch 27Mar07 6:46:35UT
by W.J. Ubbels 25 Mar '07

25 Mar '07

Hi all, with the discussion about the upcoming CubeSat launch in mind, and since we have not been able to update our website regularly just a couple of words from the Delfi-C3 office:) We are currently very busy integrating the spacecraft. Although it's a 3-unit CubeSat, it's still very, very small... so that gives some headaches sometimes:) Delfi-C3 carries two redundant (primary and backup), and almost similar radio transceivers, connected to the antenna system by a hybrid combiner which also takes care of generating the correct phase relationship between the antennas. Both transceivers consist of a UHF frontend, a command receiver, linear IF, telemetry generator and the final stages capable of 400mW RF power. Each transceiver is housed on a single 96 x 90mm board. Our tight power budget allows only one transmitter to be active at all times. Delfi-C3 contains no batteries, one of the reasons being the fact that it's primary mission is to perform a solar cell and sun sensor experiment which depend on the presence of sunlight. Therefore, the spacecraft is only active when in sunlight. Of course, since there's no such thing as a free lunch, this has made the design complicated on an other level, especially software-wise. (proper boot-up sequences etc.) The first three months of the mission are what we call the "science" mission, in which the spacecraft will be transmitting 1200 bit/s AX.25 telemetry on either the primary or backup VHF downlink frequency, frequency information can be found on our website http://www.delfic3.nl Telemetry is contained in UI frames, with roughly one frame every second. All detailed information regarding telemetry will be announced on the website as well. Modulation is Raised Cosine (in time) BPSK, more or less similar to that of the Microsats. Therefore, owners of a PSK TNC such as the NB-96/PSK-1 combo can use them with the software (written in JAVA) that we will supply (will be made available via our website). This software package connects to the TNC in KISS mode, and allows you to display telemetry in real time, and upload it to our central server in Delft. Since PSK TNC's are not that common anymore in today's shacks, and PC's are, we are developing a soundcard application in JAVA that can be used with the telemetry decoding software. An other option is to use the popular mixw program, which can demodulate BPSK and emulate a KISS TNC. After three months, the linear transponder will be activated, with a 40kHz bandwidth. In transponder mode, a CW beacon will be active instead of BPSK telemetry. This CW beacon is actually transmitted as double sideband, with two carriers spaced 1200Hz apart. It will transmit a message saying "hi hi de delfi-c3 delfi-c3". Beacon power is set at 10dB below transponder PEP, users are requested to limit uplink power to the necessary minimum to maintain a proper downlink, while not driving the AGC excessively high. Since Delfi-C3 can indeed be considered a "hardsat", with only 400mW of downlink power, it is wise to pay attention to a good receive system. The transponder IF is very basic, consisting of ceramic filter to set the bandwidth, an amplifier chain on 10.7MHz and a fast-attack / slow-decay AGC. You can listen to an audio clip of the first transponder test QSO (in Dutch...) between PA3WEG (who designed the local oscillators) and PE4WJ at http://www.delfic3.nl/wavs/Delfi-C3_transponder_link_with_QRM.mp3 (Mind you, there is some QRM in the file that might sound a bit like Leila, but this is pure coincidence) With regard to the orbit, TLE's will be anounced on the website (www.delfic3.nl) once they are available, for now I can give the following preliminary parameters: -altitude: 630km circular -inclination: 97.91 degrees -sun-synchronous -LTAN: 10:30 Ok, back to satellite building now:) Best 73, Wouter Jan Ubbels PE4WJ -- W.J.

Re: P3E transponder and launch

Hello robert- thank you for a very well written explanation of the SDX system. I understand it better now. I'm still of the opinion that the satellites should be kept as simple as possible to increase reliability and life but I also believe in democracy and it sounds like it works well here. I dont agree with your "outdated" label of the old technology. Then again, I dont buy a new car every 5 years. Oscar 7 is a good example of the ruggedness of the old technology. You're a very good tech writer, thanks for taking the time to explain, pat n2oeq ------- Original Message ------- >From : Robert McGwier[mailto:[email protected]] Sent : 3/24/2007 11:54:26 AM To : vk3jed(a)gmail.com Cc : k8ocl(a)arrl.net; Patrick.McGrane(a)aceweb.com; amsat-bb(a)amsat.org Subject : RE: [amsat-bb] Re: P3E transponder and launch Thanks to everyone for the comments, concerns, and thoughtful remarks. SDX is no magic bullet. It cannot perform any better than the analog hardware around it and our careful work on doing the mixed signal work and even more careful work to make sure it survives the rigors of traveling through Van Allan radiation belts four times a day! That said, it provides us with several things. The DESIGN of the SDX will allow us to use a high dynamic range receiver in comparison to those we have flown before and to actually realize the potential presented to us by this receiver. If we have this high dynamic range receiver, we can use a much lower noise floor and wider dynamic range transmitter to provide cleaner signals. This will be evidenced, if we do it right, by us no longer hearing the noise floor of the transponder. Next, if we have sufficient DSP horse power, we will be able to mitigate PAVE PAWS pulses by doing pulse detection and subtraction. THIS IS A LINEAR OPERATION. It will be much nicer than clipping. If the pulses get so large that we are clipping then all bets are off but with an 80 dB dynamic range receiver, this will be much less likely to happen. Stephensen has done a detailed analysis of this and this is available on Eaglepedia. Next we are designing in the ability to provide the most capable HELAPS we have ever done. HELAPS is high efficiency linear amplification by parametric synthesis. Technical papers by Karl are on both the AMSAT and AMSAT-DL web sites. It is envelope elimination and restoration amplification. It allows us to use very high efficiency nonlinear amplifiers in the transmit chain and then have the "envelope" of the hard limited signals from the transponder imposed on the signal just before it hits the antenna by modulating the voltage on the last or last few stages. If we do the final transistors and the driver, we can get VERY high efficiency compared to what we have achieved in the past WITHOUT all of the poor IMD we lived with to get the efficiency. SDX is THE enabler in this. SDX provides us with the ability to easily find all alligators and impose our will on them. There will simply be no benefit to running an EIRP that is larger than we decide to allow because YOUR INDIVIDUAL signal will be suppressed! Juan Rivera, WA6HTP, and his team are building the fancy receiver which has been designed by KD6OZH and peer reviewed to death by others. Parts are being purchased NOW and the goal is to have four soon. We are building at least one to fit the P3E box shape. Marc Franco, N2UO, has designed, using modern parts that are very difficult to get without connections, a serious 2 meter final stage. It will provide the highest efficiency 2 meter transmitter we have ever flown for HELAPS. Steve Hendricksen, a TCNJ engineering student, design a S band amplifier in a senior engineering project directed study for Marc, Al Katz (K2UYH), and I. He submitted this for competition in an amplifier efficiency contest. He received an honorable mention and came in very high in the rankings. However, his amplifier was the only one well in excess of the minimum power, at 2.4 GHz rather than 1.0 GHz (the contest minimum). As always there is the balance between "new with great promise but untried" and "the old, standard but somewhat outdated". We can have this argument all year and it will never be easily resolved. AMSAT-UK has agreed to provide SDX software working with P3E and Eagle teams. They have agreed to copy the AO-13 RF if none of these fancier elements shows up and works. AMSAT-DL is planning for these contingencies. So we have arranged for a small trial: Suisat-2 will carry a low power SDX with a few of these capabilities. We are planning a very large AMSAT engineering activity for this coming summer which you will hear more about in the coming weeks. I could go on but what I want to promise is this: I have been extremely busy both professionally, personally, and with AMSAT things and I have not done an Engineering Notebook in a while. I will do a detailed paper on this for the next journal and it will be in my engineering notebook. Following publication I will put the document with more backing material on Eaglepeda as well and give it to AMSAT-DL for both our sites.

Delfi C3 is really leading the way in this field, and some of the compromises it makes are instructive. It has a transmitter power of, 400mW, 6 to 10dB below what we are used to in LEO linear birds. It also has no batteries, and will therefore work only when illuminated. I expect that the power trade-off will be acceptable and that a fixed-elevation directional antenna with LNPA will still work well, though CW might be more popular on this bird :-) There seem to be many AMSAT operators who use large Az/El systems for LEOs; perhaps, then, an even weaker transmitter on 2m might be acceptable. My vote would be for an S-band downlink. It would be possible to put a patch antenna on one face, but some of this gain is eaten up in increased 'path loss'. Such a bird could be called a 'HardSat' in contrast to the so-called FM 'EasySats' :-) 73, Bruce VE9QRP

OSCAR-11 Report
by Clive Wallis 23 Mar '07

23 Mar '07

OSCAR-11 REPORT 23 March 2007 OSCAR-11 celebrated it's 23rd birthday on 01 March 2007. Congratulations to Professor Sir Martin Sweeting G3YJO, his team at the University of Surrey and associated radio amateurs for their magnificient achievement. During the period 14 February to 22 March 2007, the satellite was heard from 18 to 28 February and from 11 to 21 March . Good steady signals have beeen heard on most passes, and good copy of the telemetry obtained. The on-board clock has comntinued to maintain accurate time. However, there are two problems with the date and time display in the ASCII telemetry. Firstly, the date counter appears to be incrementing correctly, but the day of the month is reset to 41, at the end of each month, instead of being reset to one. A likely cause is that the unused bit representing 40 in the ASCII code for the day of the month, is permanently stuck at a one. This may be related to the '0=' display error when the month was 09, previously reported. The second problem, is that the hours are incorrectly counting and/or displayed. Since August 2006, the hour count has never exceeded 12. During one pass recently the hour count changed from 12 to 01 instead of to 13! A possible explanation is that the time/date chip has two modes of operation, which are switchable between 12 or 24 hour modes. An internal chip fault or an external circuit fault may have switched the chip into the 12 hour mode. Investigating this problem has been difficult, because the satellite passes over the UK at roughly the same times, each day, and only a limited number of pass times are available for analysis. If the above explanation is correct, the date changes around 04:47 UTC, each day. The 'day of the week' counter operates reliably, zero representing Thursday. At the present time the total clock error is 37.21444 days slow. If the satellite's watchdog timer continues to operate normally, the beacon should switch ON around 31 March/ 01 April 2007. The satellite is in full sunlight at the present time, and will remain in this state until 20 April 2007, when eclipses start again. The eclipses are expected to continue until 23 August, and if the satellite performs as it did last year, it is unlikely to be heard, for any length of time, during the eclipse season. I am indebted to David VK5DG, David G8OQW, Etienne ZS6Y, Jeff KB2M, Geoff ZL6GA, Edward BX1AD, and Sil ZL2CIA for their reports. Many thanks. The current status of the satellite, is that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 are still working. The spacecraft computer and active attitude control system have switched OFF, ie. the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed. When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus. After 22 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude. The watchdog timer now operates on a 20 day cycle. The ON/OFF times have tended to be very consistent. The average of many observations show this to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website. If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear. The website contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry.
