I havn't gotten a ROUND TUIT yet.
by John Hackett 06 Feb '08

06 Feb '08

Hi Thomas, Thank you. I've got it all sorted out now. In fact, I suspect that which Amsat-UK have on the video as X-3 may well have been an Orbcomm satellite on 137.560Mhz ... but I may be wrong ... I havn't gotten around to checking the TLM yet. I have the Orbcomm software so it should be easy to compare. I put the X-3 keps into NOVA and InstantTRACK so it will be relatively easy to check - when I have time. Thanks again for the X-3 keps. 73 John. <la2qaa(a)amsat.org> To: eu-amsat(a)yahoogroups.com From: th.frey(a)vtxmail.ch Date: Wed, 6 Feb 2008 11:05:59 +0100 Subject: Re: [eu-amsat] A lot! of felines ... or ...

A lot! of felines ... or ... Cat: Nr: 05580
by John Hackett 06 Feb '08

06 Feb '08

Hello Folks, Does anyone know where I might obtain keps for object nr: 1973 583A, catalogue nr: 05580 ??. My first shot was Celestrak but the page refused to accept the previous password it used to. (There is no facility for 'remembering' an old password). It's simply too much faffing around creating a new identity. Any suggestions and I'd be most grateful. This is the first 100% British satellite launched 35 years ago. There's a video on the Amsat-UK website showing that it's still transmitting. It was also known as Prospero X-3. USELESS INFORMATION DEPT: Prospero? ... Aye!, the Duke of Milan in William Shakespeare's ... ' The Tempest' ... read the play and you'll understand why the satellite was christened thus. 73 John. <la2qaa(a)amsat.org> From: archie.hackett(a)hotmail.com To: g7hia(a)btinternet.com CC: john(a)manchester.ac.uk; allan_gm1sxx(a)hotmail.com Subject: Cat: Nr: 05580 Date: Wed, 6 Feb 2008 01:28:29 +0100 Hello John, Re: the Prospero X-3 satellite. It's object nr: 1973 583A, catalogue nr: 05580. I've listened to the Amsat-UK website audio recording and noted the frequency as 137.560 WFM ... but I can't find any keps anywhere!. Any ideas where I might find current keps ??. I tried the CelestTRACK website but it refuses to accept my password since I last checked in a year ago. The Wikipedia page noters that it was decomissioned long ago but that it's still transmitting ... with an estimated life of 100 years. Interesting power situation there ... nuclear based ??.

LVB tracker display problem - solved
by Fer IW1DTU 06 Feb '08

06 Feb '08

I changed the 2x16 LCD and now LVB works fine. Thanks Howard and all for advises 73 Fer Hello Wondering if someone can help. I just finish to build an LVB tracker for a friend of mine. All works fine with NOVA but during a satellite pass the display stuck as in the picture: http://it.geocities.com/supertrackmoon/lvb_display.jpg All other functions are OK and the tracker is still tracking the satellite. A quick restart (power off / power on) and display works again but after some minutes it is again stuck. It seems just only a display problem. Same behavior with other satellites passes. I built a couple of LVB units and I have been using an LVB tracker with NOVA for years without problems. Any ideas ? Fer IW1DTU

Can someone point me to a simple S-band helix construction article?
by Michael A. Tondee 06 Feb '08

06 Feb '08

I can find plenty of information on helices and the theory involved with them but a lot of it seems to be contradictory and confusing.. I've found very general guideline type articles but what I haven't found yet is a simple step by step construction article from start to finish. I'd like to construct one using pvc pipe as the helix form if possible as it is readily available but I even find varying opinions on the suitability of that material. Are the dimensions really not that critical as has been stated in some articles? I was thinking of using schedule 40 1 and a quarter or 1 and a half inch diameter white PVC pipe. I could really use some simple formulas as my old brain starts to smoke when I see equations involving algebra and pi. Been way to long since high school! hi hi. Tnx and 73, Michael, W4HIJ

05 Feb '08

Hello I heard myself the last pass over the US. Very low elevation from Seattle. The first time on satellite L band, looking for contacts next pass. Receiving on 70cm. S band rx is down, long story. Do we adjust doppler with the higher frequency. Or keep it on 1268.7Ghz. -- 73 Bob W7LRD AMSAT member 28498 Seattle

AO-51 schedule updated
by Andrew Glasbrenner 05 Feb '08

05 Feb '08

I updated the AO-51 schedule text page last night at : http://www.amsat.org/amsat-new/echo/CTNews.php . Update: February 3, 2008 The AO-51 committee has completed a schedule for February. We will continue the V/US repeater mode that began on January 25th for all of February, except on Tuesdays through Thursdays when we will switch to L/US. This pattern will repeat every week in February except that the mode switch from V/US to L/US on Tuesday the 12th will be delayed until Wednesday the 13th to accommodate a School Roundup event at Two Rivers School in North Bend, Washington. The S-band downlink may be temporarily suspended for WOD telemetry download without notice. Generally this will only be for one pass per day. Regarding the graphic schedule...the software that does the schedule will not allow for the proper display of the current modes. Please refer to this page for mode change information. February 2008 AO-51 (AMSAT Echo) Schedule February 1 until February 29, subject to modification February 1 - February 4 FM Repeater, V/US Uplink: 145.920 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 5 - February 7 FM Repeater, L/US Uplink: 1268.700 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 8 - February 12 FM Repeater, V/US Uplink: 145.920 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 13 - February 14 FM Repeater, L/US Uplink: 1268.700 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 15 - February 18 FM Repeater, V/US Uplink: 145.920 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 19 - February 21 FM Repeater, L/US Uplink: 1268.700 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 22 - February 25 FM Repeater, V/US Uplink: 145.920 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 26 - February 28 FM Repeater, L/US Uplink: 1268.700 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM February 29 - TBD FM Repeater, V/US Uplink: 145.920 MHz FM, NO PL Tone Downlinks: 435.300 and 2401.200 MHz FM 73, Drew KO4MA AMSAT-NA VP Ops

All the facts are wrong but
by Bob McGwier 05 Feb '08

05 Feb '08

Sent from Express News TEHRAN, Iran - Iran launched a research rocket Monday and unveiled its first major space center, which will be used to launch research satellites, state-run television reported. The report said the rocket was the first launched by Iran "into space." But analysts have expressed doubts about similar technological achievements announced by the country in the past. Iran launched its first domestically built rocket last February, which did not reach orbit level. "The first Iranian rocket Explorer-1 was fired into space," reported state TV, which showed live images of the event at the space center, with President Mahmoud Ahmadinejad issuing the launch order. "With the launch, Iran has joined the world's top 11 countries possessing space technology to build satellites, and launch rockets into space." The report did not specify the altitude reached by the research rocket. Space is considered to begin at 60 miles above ground. Ham radio satellites - the lowest flying satellites - orbit between 100-300 miles, while communication, weather and global-positioning satellites fly between 250-12,000 miles up. Some Western experts also have raised the possibility that Iran's space program may be a cover to more fully develop its military ballistic missiles, a prospect many find troubling at a time when the U.S. and others worry Tehran is trying to develop nuclear weapons. Before the launch, Ahmadinejad opened the space center, which includes an underground control station and space launch pad, according to state TV. By ALI AKBAR DAREINI Associated Press Writer

Explorer I - recordings
by Roy 05 Feb '08

05 Feb '08

I have been asked if any of the Explorer I recordings were still available in WAV, etc format. There is one posted at http://www.amsat.org/amsat-new/index.php. Select the "Select a Topic" drop down menu and scroll down to "Sounds from the first satellites." There are a few recordings there with the info about the recordings. One of them is the Explorer I telemetry. You will hear several constant audio tones with one of them shifting between two tones. There was a geiger counter on board that counted cosmic ray particles according to the info I have read. After a certain number had been counted the tone shifted and after another quantity had been counted it shifted back again. The 108 mHz antenna was a six element colinear arrangement consisting of six half waves (wire elements) suspended over a 13x13 ft wooden frame covered with chicken wire laying on the roof of my house. This oriented it up about 75-80 degrees above the southern horizon. No tracking. The satellites had to fly through the main lobe of the antenna pattern. The receiving arrangement was a modified TeCraft (I think) converter with a 6BQ7 TV RF amplifier front end feeding an National NC-300 Amateur band receiver. Not very good as noise figures go today but pretty good for 1958. I still have all of the original reel to reel tapes, some of their contents transferred to cassette tape. -- Roy

Fw: FM narrow mode for DOPPLER.SQF file (for ISS)
by Charles Reiche 05 Feb '08

For anyone that has a 910 and satpc32, here is a chat I had with DK1TB. Charlie N3CRT ----- Original Message ----- From: Erich Eichmann To: Charles Reiche Sent: Sunday, February 03, 2008 4:12 AM Subject: Re: FM narrow mode for DOPPLER.SQF file Hi Charles, at present SatPC32 can't switch the IC-910H to FMN. The manual mentions only a CAT command for FM (cmd 4), but no command for FMN. Meanwhile I know that there are undocumented commands that switch the IC-910H to FMN (cmd 5 sub cmd 2. I have just tested that and it works (with the IC-821H and other Icom radios this command doesn't work at all). So, I think, I can modify the program with the next update and include the special FMN command for the IC-910H. 73s, Erich, DK1TB ----- Original Message ----- From: Charles Reiche To: dk1tb(a)amsat.org Sent: Sunday, February 03, 2008 1:21 AM Subject: FM narrow mode for DOPPLER.SQF file Im am learning the ins and outs of your fine program, but I have run into a stumbling block... I have an Icom IC-910h connected via a rigblaster PNP. My file entry for ISS voice mode reads as follows: ISS,145800,437800,FM,FMN,NOR,0,0,Cross band repeater The sub band refuses to go to Narrow mode. If I turn off CAT I can manually enter the sub band and press and hold the FM button to enter Narrow mode but this gets reset to FM on the next tune cycle. I have also tried setting both bands to FMN, without sucess. Is your program capable of setting this mode on my Icom? I am using version 12.6 Thanks Charlie N3CRT

Dispelling a myth.
by John Hackett 05 Feb '08

05 Feb '08

I was rather amused at a question I received the other day ... "Why wasn't Great Britain involved in space?" ... like America, Russia, Japan, India and China. Errr ... I wonder if the words Jodrell Bank, Blue Streak, Woomera ... and in more modern times, SSTL would mean anything to the person who asked the question. How about the "other" magician ... MERLIN - (anno 2008) ... MERLIN = Multi-Element Radio Linked Interferometer Network. MERLIN operates at frequencies from 151Mhz to 24Ghz. At 5Mhz the resolution of MERLIN is better than 50 milliarcseconds, (quote) ... "somewhat greater than that of the Hubble telescope" ... (unquote). Oh, I'd say Great Britain 'is' involved in space. Perusal of the JODRELL BANK web pages ought to dispel any myths as to whether the 'Limey's' are involved in space or not. The Lovell telescope - (76m) - is the centrepiece of an impressive array of dishes on my old stomping ground at Holmes Chappel - it is also available with it's own "live" web pages. If "precision" - (space tracking) - is your thing I'd suggest you check out the parameters ... where "error" is quoted as ... 0.0000 in azimuth and elevation ... and the diameter of the main dish is *only* 76 meters. The Russians asked the 'mad professors' at Jodrell Bank to help track Sputnik way back in 1957 ... was that early enough to justify a 'presence' in space exploration?. It wasn't just the Germans who messed about with RADAR and clandestine radios in the war, you know. I can tell you ... when you start getting 'whacked' on the head by V1 rockets chucked at you from Germany, you start taking an interest in 'space'. 73 John. <la2qaa(a)amsat.org>

Automatic doppler tracking of DSB
by James Whitfield 04 Feb '08

04 Feb '08

I am trying to find out if there has been any development of a frequency tracking system to compensate for doppler shift, or at least find a person or organization with which to discuss concepts. I tried to contact AMSAT about this more than a week ago, but there has been no response. I have tried to contact AMSAT again, and decided to try this bulletin board as well. It started when I read that AO-16 had been placed in a test mode with an FM uplink and DSB downlink. I remembered a diagram of a double sideband suppressed carrier ( DSB ) demodulation technique that used a variation of a phased locked loop to recover the frequency and phase of the original carrier. I realized that it should be able to track the "original carrier" through the doppler shift caused by the relative motion between the satellite and the receiving station. I decided to find out more about the concept. I was not able to find any reference to the technique having been used with satellites, but I believe the system is called a Costas Receiver, or perhaps is refered to as a Costas Loop. If someone knows if this was used for doppler frequency tracking, please let me know where I can get more information. If there is a person or organization that would be better suited to my inquiry, I would like to know that as well. Thank you. James Whitfield n5gui

PacComm RF Modems
by Stargate 04 Feb '08

04 Feb '08

Hi all, I have 3 PacComm RF modems that I'm trying to figure a good use for. I looking for any information regarding them such as programming, interesting ideas to use them for, ect.... These look like they were AVL units since they have a GPS receiver board inside them and a Midland 70-201BD UHF data/voice transmitter as well. There are 3 units with the model numbers.... 1. "Base station" (no GPS receiver in this one) 2. "Head" 3. "Tail" Here are a few pictures.... http://mysite.verizon.net/vze1ool9/paccomm/paccomm1.jpg http://mysite.verizon.net/vze1ool9/paccomm/paccomm2.jpg http://mysite.verizon.net/vze1ool9/paccomm/paccomm3.jpg http://mysite.verizon.net/vze1ool9/paccomm/paccomm4.jpg http://mysite.verizon.net/vze1ool9/paccomm/paccomm5.jpg I have SOME information on reprogramming the Midland radio's inside but I'm still trying to find the schematic for the programming adaptor/cable. I've located the ACC900 software and some schematics for the Midland data radio but I haven't found anything for the complete PacComm unit or the radio programming adaptor yet. Does anyone have any information thay can be provide about these? These might make great APRS units if I can figure them out. The Midland radio's have "9.6kb mod" written on them so they must have already been modified for that speed. From what I have read, the Midland radio's can be used up to 19k2. I have talked with PacComm and they are looking for information for me but I thought someone here might be knowledgeable about them. I hooked them up to my serial port and they seem to take a few common packet commands. Any interesting ideas or help/info would be appreciated very much! Thanks, RoD KD0XX

Congratulations to Martin, Jeff and SSTL! Eric W3DQ Washington, DC ------------------------------ SSTL Wins Canadian Deal February 1, 2008 [Satellite Today – 2-1-08] Surrey Satellite Technology Ltd (SSTL) won a contract from MacDonald, Dettwiler and Associates Ltd. (MDA) to deliver a satellite platform as part of the Sapphire space object surveillance program, SSTL announced Feb. 1. The two-year program is part of a contract from Canada's Department of National Defence valued at 65 million Canadian dollars ($65.2 million). The contract has options that cover mission support, operations and maintenance. The mission will provide a satellite-based resident space object observing service that will provide accurate tracking data on deep space orbiting objects. Sapphire will feature a space-based data collection platform for continuous surveillance of man-made objects in medium- to high-Earth orbits (6,000 to 40,000 kilometers). The data collected will be processed by a ground-based system and the results will be used to update the U.S. Satellite Catalogue used by North American Aerospace Defense Command and Canada to provide space situational awareness. ----------

The problem is, besides probably being cost prohibitive, you blow your 250mW power budget out of the water with the FPGA. Using Actel's Power Calculator spreadsheet and the specs from the ARM7 IP Core datasheet, you're looking at a worst case of 543 mW with just the core in the 250k gate version and up to a watt in the bigger versions. That said, thanks for the input. The team needs this kind of input to guide them in their decision processes.

Sat DX

Of the 227 countries I have worked on satellite my most memorable one was with HC8/XE1KK (Galapagos) on UO-14. UO-14 was a single channel FM bird with an altitude of about 800 km. The distance from my QTH to there is 3277 miles which by itself is no record. I had worked Ramon on 10 meters and I mentioned I spent most of my time on satellites. He immediately came back saying he was working sats from there and he would love a contact with me. I looked at Instant Track and found we had a mutual window for about 3 minutes the next day with a max elevation of about 3 degrees for each of us. As well the path would be over North America in the afternoon with lots of activity for QRM. I didnt have much hope I would hear him let alone make an exchange. However we managed to do just that. I have his card dated 27 Mar 2002 Clare VE3NPC
