W7W via satellite, "Westfest" hamfest in Glendale AZ, 13 January 2007
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Jan '07

15 Jan '07

After my first time working at an AMSAT hamfest table last month, I was looking forward to this hamfest on the west side of the Phoenix area. Gerry VE4GTB/KD7MDB and I took care of the table, and we answered lots of questions and had 4 passes (2 on SO-50, 2 on AO-51) for demonstrations that attracted the interest of the hamfest crowd. We had a good time despite the bitter cold and small turnout, and also sold a fair amount of AMSAT items to hams looking to try the satellites themselves. The hamfest organizers, the Thunderbird Amateur Radio Club (W7TBC): http://www.w7tbc.org/ had requested the special callsign W7W for use by their HF special-event station. Gerry had asked them if we could also use the W7W call during our satellite demonstrations, and we were told, "Sure." I posted an announcement on the AMSAT-BB mailing list and on a few other lists of the upcoming satellite activity, and we were ready to go. Saturday morning started early... I arrived at the hamfest site at 0530 local (1230 UTC), and Gerry was already there. We were told by the organizers to set up next to their HF station, and one of the Thunderbird club members made sure we had a covered spot in case of rain. We set up our tables with the AMSAT merchandise and my equipment (IC-2720H mobile radio, 12V/20Ah gel-cell batteries, Arrow Antennas handheld Yagi, Sony digital voice recorder, external speaker, laptop with Nova running during the demonstrations to show where the satellites were). Our first pass was on SO-50 at 1317 UTC, and we were ready for that. The first SO-50 pass went from south to east, and since it was an early pass we were not sure there would be many stations showing up. We made 2 contacts during the pass, with Angelo N5UXT as our first satellite contact as W7W (thanks for being up early, Angelo!). One other contact before the end of the pass with a VE3, and then back to answering questions until 1500-1520 UTC and an SO-50 pass followed immediately by an AO-51 pass. The SO-50 pass around 1500 UTC went to the west, and being early for those in western North America I did not expect much activity. We were happy to make 3 contacts, two Mexican stations plus Zach KM7I in Seattle before we moved over to AO-51. We heard the announcements from Gould WA4SXM that there was testing in progress, so we kept listening and hoping the satellite would be available for part of the pass since it would cover most of North America. The testing ended, leaving a couple of minutes to make 2 quick contacts before the satellite went out of range. The final AO-51 pass, around 1647-1702 UTC, started out with a surprise. The crowd and I heard a couple of hams chatting on 435.310 MHz, which was where I ready to hear AO-51 at the start of the pass. I quickly went onto that frequency and asked those hams to move to another frequency, which they did, and then we made 10 contacts with stations in the western USA, Alaska, and Mexico to conclude our satellite demonstrations. Larry WA6DIR in California was the last station in the W7W satellite log. At the end of the morning, we had a total of 17 contacts in our satellite log. We made 12 contacts on AO-51 and 5 on SO-50 with stations in 8 US states (Alaska, Arizona, California, Louisiana, Montana, Ohio, Oregon, and Washington state), one Canadian province (Ontario), and two Mexican states (Baja California and Zacatecas). The hamfest organizers now have a copy of the satellite log, to combine with their HF log for their records and to be able to answer any QSL requests from the satellite demonstrations. Gerry and I will have the AMSAT table at the next Phoenix-area hamfest, the Scottsdale Amateur Radio Club's "Springfest" on 10 March. I will come back to the Thunderbird Amateur Radio Club for their meeting on 15 March, to do a presentation on amateur satellites and AMSAT. Thanks to everyone who stopped by our table, and for those we made contact with on the satellites. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

These are interesting ideas. I wonder if a cubesat project such as this would provide a workable test-bed for one or more layers of the proposed Eagle text-messaging service, which then could be bridged in software to the ground-based messaging you propose. I'm not sure if this is what you have in mind, but some Linksys WiFi boxes have enough RAM to run a stripped-down version of Linux. The trick would be to get the data into them. The WRTSL54GS has a USB port, reputedly for network storage, but it might be hackable in order to get serial data from a TNC or other demodulator using a USB-to-serial bridge. It might be in AMSAT's interest to partner with a Cubesat project to explore this. I understand the processing power onboard a cubesat would be much less; but just as Suitsat II will test the SDX, a flying testbed for SMS would be great. It would make for an excellent sales-pitch at conventions, etc.: imagine a table with a radio, demodulator and hacked WiFi box, and a couple of laptops. When the bird is in range, a Jabber-based messaging program comes alive with contacts across N. America. for 8 minutes or so. Then the pitch: you can help make this system work for hours-on-end across a large part of the globe with your donation to Eagle. 73, Bruce VE9QRP

Yaesu 5400
by Paul Luggar 15 Jan '07

15 Jan '07

I have one of these that was given to me some time ago which I plan to use this summer. So I thought I would repair it. The plastic covers of the terminal connections have cracked and need replacing, I either need a source for them or the same socket as my 5500 would allow me to swap them over. (My 5500 has a failed pot I think) does anybody have a source for these bits? I tested the 5400 last night and all's working fine except: The azimuth rotator refused to move CCW until I worked CW/CCW a few times, I'm thinking thats a sticky relay in the control box as it was totally silent when the CCW button was pressed. That will possibly cure it's self with a bit of use as it's working now. The elevation feedback was erratic to start with but has now settled down, I'm supposing dirty pot in that one which will also cure it's self with a bit of use. The issue I really have is should I strip them down? Both have quiet operation C/W and elevate but both are nosier on return CCW and descend. I checked the bearings on the elevation unit through the inspection cap and under the terminal screws and they look fine, shiny and greased. I'm unable to check the azimuth unit without cracking it open. What's the feeling on preventative maintaince on these units? Does anybody add a drain hole to them? Which I could not find or they are blocked. 73 Paul Luggar M0SCI Website WWW.M0SCI.CO.UK Amsat-UK Member 6484 www.m0sci.co.uk/forum Devon and Cornwalls Amateur Radio Message Board

SatPC32 Question
by sraas＠optonline.net 14 Jan '07

14 Jan '07

Just recently on my last fo-29 pass.. I attempted to have SatPC32 do my doppler correction for me. This is what I noticed.. and I am looking for any Ideas. When I found my downlink freq using the VFO mode the doppler would jump every 5-6 seconds.. not a smoothe tune. and eventually I lost my downlink freq altogether. How often does the program tell the radio to move the frequency? I have it set to the recomended 90 setting.. Im just wondering is this normal.. or should it smoothly tune a ssb signal at all? -Steve Raas N2JDQ FN20vg

One last "brainstrom :-) : I see ISS is in close proximity (haven't checked PCSAT-1, that would be even better to pick up the packet burst) to the satellite. Any chance of getting one of the astronauts to turn the radio to 145.825MHz? After all, they're not TOO busy, huh?? :-) . Seriously, they have a scheduled school contact on the 16th, maybe we could get them to QSY for a few mintues, assuming the satellite is is within range, assuming antenna orientation on both ends is "good". tnx es 73 Bruce In a message dated 01/14/07 08:19:35 Greenwich Standard Time, ko6th_greg(a)hotmail.com writes: > Can someone describe how to pronounce the name of this latest Amsat gem? > > Thanks, > > Greg

Re: KR-010
by Roy 14 Jan '07

14 Jan '07

Hi Andre, I used to have a KR-010 and there was no program for it. You send ascii code for U (up), D (down), L (left) and R (right) to control it. You must have a tracking program that sends these codes to the KR-010 to control it or do it manually from your PC. My very first ORBITS II program was setup to control the KR-010 but I dropped the KR-010 support when the KCT came out and programmed to support it instead. I'll look around and see if I still have the KR-010 documentation. I'm not sure that I ever had any, other than verbal instructions. Somewhere I still have the KR-010 packed away however. -- Roy -- W0SL

Linear link budgets
by Grant Hodgson 14 Jan '07

14 Jan '07

Unfortunately, the calculations for dividing transponder power equally amongst users are not as simple as have been suggested. For the 400mW case :- assume that 400mW is the maximum power that the transmitter can produce. Then a single CW signal could in theory be sent at a power of 400mW, assuming no AGC, beacons etc. However, if 2 equal level CW signals were being transmitted, then the Peak Envelope Power of these 2 signals would be 6dB higher than each of the signals individually. This is because the voltages of each of the 2 CW signals have to be added together, giving a peak signal with double the voltage of each signal, which is 4 times the power or a 6dB increase. Therefore, to keep within the 400mW limit, each CW signal would be restricted to 100mW each. The same analysis can be done for 3 equal CW signals, where each would be 9.5dB down; i.e. 44mW each etc. For SSB signals, the same analysis can be performed by simply taking the PEP of each SSB signal; so one CW signal could co-exist with one SSB signal, both of which would have a downlink power of 100mW. The above is actually a slight over-simplification, as it takes no account for compression etc, but serves as a useful example. As Graham mentions, a beacon may be present at a much higher level than the rest of the transponder, which makes the analysis slightly more complex, but the principle remains :- It's the PEAK power that limits the RF performance of linear transmitters, and that is valid for all linear transmitters. regards Grant G8UBN

I finally got around to looking at The Langrangian points referred to in your mail. - Thanks for that pointer, it's a really interesting piece of physics. Good fun looking it all up. At a first 'pass' it would appear that maintaining a satellite at the L1 and L2 points would require some station keeping, hence fuel. They would give excellent coverage from 56,000km / 200,000km respectively. Tracking the one held between the sun and earth would give really simple tracking. Start by pointing at the sun and then move around a little to peak the signals. - Of course the disadvantage is that instead of cold sky you would have all the Sun noise. The L2 point is only visible at night...so may be a bit 'antisocial' for practical use. - I wonder how the eclipse works out there? The ones I found most interesting were the L4 and L5 points. Areas of space where satellites are held in a stable position by gravitational forces alone without needing any fuel. Big problem there is the distance. At 60 degrees ahead and behind the earths orbital position would make the path loss huge. Also, apparently, those areas tend to gather space dust, rocks etc. Probably a bit of a risk for collision albeit at low relative velocity. Very thought provoking 73 David G0MRF >From Wikipedia: The Lagrangian points also Lagrange point, L-point, or _libration_ (http://en.wikipedia.org/wiki/Libration) point), are the five positions in _interplanetary space_ (http://en.wikipedia.org/wiki/Interplanetary_space) where a small object affected only by _gravity_ (http://en.wikipedia.org/wiki/Gravity) can theoretically be stationary relative to two larger objects (such as a _satellite_ (http://en.wikipedia.org/wiki/Satellite) with respect to the _Earth_ (http://en.wikipedia.org/wiki/Earth) and _Moon_ (http://en.wikipedia.org/wiki/Moon) ).

Hi Amsaters The cubesat team at the University of Louisiana is in the process of defining its second mission for its cubsat project. The team has decided to fly a cubesat that has a educational component. We are asking for ideas that would excite K through 12 students that can be flown on a cube sat i.e. 1 watt of dc power in a 4 inch cube. In addition to the education component the team is thinking of flying a high efficient radio per haps bpsk with a forward error corrected code with Eb/No of < 3 db. Again here we are asking for input in the mission definition and help in the implementation including pier review. Please put your vision in gear and help us. thanks nick K5qxj

That makes it easy to do maintenance to the antennas and rotors. It's also easy to move the antennas for field day. During daylight I can sit at my operating position and see the antennas through a window directly in front of me. It's great to get visual feedback that the rotors are working correctly and that the antennas haven't slipped on the crossboom. The main disadvantage of ground mounted antennas is that more of the sky has obstructed S-band reception from surrounding buildings, trees, and hills. With a good preamp I have no problem receiving solid U-band downlinks through trees. I strongly recommend a mast-mounted preamp for the UHF antenna. I look forward to hearing you on the air.

Hi! I haven't been keeping a close eye on the AO-27 web site lately: http://www.ao27.org/ but there was a new report posted last Saturday (6 January): "We have successfully reset the cpu on AO-27. AO-27 is now commanable and is sitting at the bootloader. We are beginning the process of uploading flight software. The transmitter was very strong during our tests. This is very good news." Here's hoping they are able to reload the software and bring that old satellite back to life again. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

W7W on AO-51/SO-50 Saturday morning...
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Jan '07

13 Jan '07

Hi! Just a quick reminder that I will be operating W7W from the Westfest hamfest in Glendale AZ (west-side suburb of Phoenix) on AO-51 and SO-50 passes between 1300 and 1700 UTC Saturday the 13th. I could be operating with an HT and handheld Yagi if the weather is really bad here, but I plan to be on from there. The hamfest organizers will also have W7W on the HF bands during the morning, if anyone is interested in trying to hear them on other bands. More information, including the QSL details, can be found at: http://www.w7tbc.org/Westfest.html 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Recent VO-52 Pass
by sraas＠optonline.net 13 Jan '07

13 Jan '07

I had a rough time of recieving the downlink tonight.. I herd a few responding to my call (cw) but the fade was just too much for my 1/4 wave vert. I did complete a QSO with K9QHO lastnight, strong-arming the uplink yagi.. following in SATPC32 and having the PC do the cw work for me with CwType. It was a bit of a comedic act.. but It was nice.... I was able to also record with my windows sound recorder. Not an easy act with an 11 ele yagi in hand .Ohh I forgot to mention that I was dooing the dopler correction myself as well, as my CW program needs com 4 as my SATpc32 does too.. and they cant share. ( using a rigblaster plug & play as a com port emulator ) If any one is interested in listening to this contact I have it uploaded to a pseudo web page I threw together on Yahoo Groups. This is where I will be putting my log book as well for a back up in case I loose the data. The yahoo group is here : http://groups.yahoo.com/group/SatelliteLogBook/ This weekend I plan on constructing the framework for the base of my GME 4.5' quad pod. It will be ground monuted.. and then I can work on figuring out a rotor option. Being one that hates to do things in a 1/2 donkey mannor.. This may have to wait a bit because I dont want to cut corners on quality... and the Yaesu 5500 seems as the only viable option.. especially if I want ease of installation/use and computer interface. Being ground mounted is going to be my saving grace as if I have a problem.. it will literally be right outside my window. 73's for now Steve Raas N2JDQ FN20vg

AO-7 Mode A
by RaySoifer＠cs.com 12 Jan '07

12 Jan '07

Today at 1700 GMT, AO-7 came up in Mode A and stayed there for the entire pass. I had no trouble getting in with approximately 100 W eirp, producing an S7 downlink signal through my very unremarkable 10-meter receiving system: a Ten-Tec Argonaut V and a Hy-Gain AV-640 vertical antenna. The beacon, on 29.502, was at about the same strength. There was only one problem: mine was the only signal in the passband. Moral: if you don't find AO-7 on Mode B (U/V), try Mode A. You might be pleasantly surprised! 73, Ray W2RS

Re: PCSAT controller
by Robert Bruninga 11 Jan '07

11 Jan '07

> What sort of computer / controller is on PCSAT ? None, all of my sateliltes, PCSAT-1,2,ANDE,RAFT,MARScom are nothing but KPC-3's or KPC-9612's. Just a TNC and a radio. I use the built in telemetry, remote sysop and I/O commands for all functions. The KPC-3+ gives me this: 1) Low power (15 mA) 2) serial port to any aux devices 3) password protected remote control 4) 5 channels of analog telemetry 5) 3 to 5 external ON/OFF and PULSE commands 6) Beacons, 4 bulletins, on any schedule 7) CW (if you want it) 8) Flying BBS (file store and forward) 9) APRS digipeater A) GPS parsing and position reporting And with an external $199 voice synthesizer, we get packet to voice. The KPC-9612+ gives all of the above PLUS 10) 1200 and 9600 baud ports 11) Cross baud digipeting 11) 6 to 8 ON/OFF commands lines 12) Additional 8 bit bidirectional I/O discretes All we add are the needed relays and telemetry voltage dividers. If we need more than 5 telemetry channels, we use some $2 analog multiplexer chips to give us up to four frames of 5 each for a total of 20 channels for PCSAT1,2 and ANDE. Then we make clever use of all the hundred or so TNC commands for everything we need to do... Bob,Wb4APR

Antenna Thoughts / QSL'ing
by sraas＠optonline.net 11 Jan '07

11 Jan '07

As being new to the sats I am learning new stuff every minute. I have recently made my 1st contacts on AO-51/Oscar-50 on FM getting close to 10 qso's in all. My current antenna set up is a 1/4 wave verticle in my living room on 2m .. and I have been strong arming the 432 yagin to recieve the downlink. I do have 5 elememt 2m yagi for the uplink.. but im not using it at the moment. In doing this I am finding that keeping the antenna verticly polarized or 1/2 way inbetween vert and horz is providing me the best RX results. I guess what Im tryin to figure out is before I mount these outdoors.. is this typicle? If so I will mount them 1/2 way between vert and horizontal polarization. Circ. polarized antennas are not an option for me right now.. but I will go that way eventually. My 2nd subject is in reguards to qsl'ing... do most Sat users use some sort of electronic qsl ie. LOTW or e-qsl? Or is the ole reliable snail mail qsl the most common? -Steve Raas N2JDQ FN20vg

Crossbooms ... my pennyworth.
by john hackett 11 Jan '07

11 Jan '07

Hello All, Stating the obvious ... if one mounts the aerials as per a Wimo satellite X-Quad ... (using counterweights if necessary) ... one eliminates the crossboom problem entirely. I've compared this kind of system against my more usual 2 x 6 + 2 x 6 homebrew array for 2m and 70cm ... (each aerial mounted at 45 degrees in relation the other) ... and correctly phased for switchable CP. In my humble opinion, on LEO's the squint experienced just doesn't warrant the effort of being (theoretically) correct. It did make a 'slight' difference on AO-10 and AO-13 (HEO's) but still hardly worth the effort of being "technically correct". Others may have a different opinion ... which of course, they have evey right to have. I respect that. 73 John. <la2qaa(a)amsat.org>

i have an icom 821h. sometimes when i turn it on, both the main and the sub band receive lights are flashing together from green to orange. when this happens, i can transmit fine but there is no audio. turn it on and off a bunch of times and nothing changes. then all of a sudden one day, it will work just fine. of course in the meantime, there is no audio on either band. adjusting the squelch all the way open or closed changes nothing. i can see the s-meter move when a signal is received so that works fine. any ideas? please email me directly. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards ARRL Awards Manager (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on W0KIE Intelsat Americas, T1, 6.2/6.8Mhz Also streaming MP3 at http://www.amsatnet.com Latest satellite news on the ARRL Audio News http://www.arrl.org

RAFT Satellite PSK-31 mode next week
by Robert Bruninga 10 Jan '07

10 Jan '07

Next week, we will enable the PSK-31 transponder on RAFT. This transponder is 28.120 USB MHz PSK-31 SSB uplink and 2 meters FM down. Both RAFT and ANDE (and PCSAT-1 this week) are working fine on orbit for those with a big enough OSCAR satellite array to hear the weak 2 meter downlink. PCSAT-1 is much stronger and has passes that are almost 15 minutes in length and can be worked horizon to horizon with a good beam. ANDE and RAFT are only usable above about 10 to 15 deg with a good beam for only a central 3 minutes or less. RAFT packet-to-voice mode has been enabled for the first 3 weeks and several stations have made contact... See web page: http://www.ew.usna.edu/~bruninga/ande-raft-ops.html Next week starting Tuesday 16 Jan, we will enable the RAFT PSK-31 transponder for similar experiments. Here is what it takes once the PSK-31 mode has been enabled: 1) Read the user-service-agreement on the above web page 2) Someone in the footprint must do a packet CONNECT RAFT 3) That will bring up the 10m RX and 145.825 TX for 1 minute 4) Anyone sending PSK-31 or CW on 28.120 MHz USB should be heard The transponder will time out after 1 minute (maybe later we can extend that time depending on usage). Remember that the footprint of RAFT is an order of magnitude smaller than PCSAT-1 and so it is hard to hear except when a high pass and the duration is only a few minutes. With PCSAT-1 fully alive this week and next, we are seeing over 80 different stations (the maximum depth of the live capture page http://pcsat.aprs.org ) in under 8 hours. Just today another satellite was launched onto 145.825 so now there are 5 satellites there! PCSAT-1, ANDE, RAFT, UO-11 and now Pehunesat. All but UO-11 use standard 1200 baud AX.25 packets.

My crossboom is a light steel tube, with wooden dowel extensions, within the field of the antenna. These were turned down in a lathe and hammered/glued into the steel tube. To waterproof the ends, the wooden bits were stood in a tin of creosote for a week. I must admit that the feeders for the 2mtr beam do actually pass through the field, but as it has such a wide beamwidth, I would assume that any squint is going to be irrelevant. Jules

Doppler and direction calculation?
by n3wwn＠futuretek.cx 10 Jan '07

Hi! I've been trying to find the answer to this question using Google, but can't seem to find a complete answer. How can I calculate the doppler shift and direction of travel of a satellite accurately? I have the following information based on the observation point: Longitude Latitude Azimuth Elevation Range Altitude Velocity Phase Eclipse Depth Squint Angle For example (AO-27 - it's the first sat in my test keps): Sat Lon = 82.58 W Sat Lat = 27.10 S Sat Az = 182.93 Sat El = -28.64 Sat Range = 7516.62 km Sat Altitude = 799.74 km Sat Velocity = 7.46 km/s Sat Orbit Num = 69288 Sat Visibility = D Sat Phase = 317.61 Sat Eclipse Depth = -62.93 Sat Squint = 360.00 I'd like to be be able to calculate the doppler for any satellite and any frequency. I'd also like to find out the direction of travel, relative to the lat/lon coordinate system (90 if travelling east, 180 if south, 270 if west, etc). Can anyone help me out here with some equations or point me in the right direction?! Thanks! 73 de Rich N3WWN (FN00fh)

http://www.zeenews.com/articles.asp?aid=346912 <http://www.zeenews.com/articles.asp?aid=346912&sid=ENV&ssid=27> &sid=ENV&ssid=27 Sriharikota, Jan 10: The PSLV-C7, carrying four satellites, lifted off successfully from the Satish Dhawan Space Centre here. All the four satellites of the PSLV-C7 were injected into orbit at an altitude of 638.7 km, 949.8 seconds after the lift off. The entire process took 20 minutes. Based on the velocity during the first three stages, the fourth stage, an unpowered flight called `Coasting` lasted for 15 seconds, moving purely under the influence of gravity. "We have done it successfully. We have put all four satellites into the required orbit. It was a textbook mission. Our boys have done well," ISRO chairman Dr G Madhavan Nair said after the launch. The PSLV C7 carries four satellites - the 680 kg Indian remote sensing satellite Cartosat-2 and the 550 kg space capsule recovery equipment (SRE-1), Indonesia`s Lapan-Tubsat and Argentina`s six kg nanosatellite Pehuensat-1. 73, Mike DK3WN

Sat688 or LVB tracker?
by Stargate 09 Jan '07

09 Jan '07

Hi all, OK, unless some other option comes up, or there is an incompatibility problem that I am aware of, I have narrowed my list of rotor interfaces down to the following 2.... The LVB at.... http://www.g6lvb.com//Articles/LVBTracker/index.htm The Sat688 at.... http://www2.arrl.org/FandES/tbp/ariss-kits/ I have a Yaesu G-5500 and a FT-847 for the rotor and radio respectively. I intend to use Orbitron for my tracking and radio control software if the above interfaces are compatible. The computer is a PIII 650mhz with 1 serial and 1 USB port. I was thinking of using the serial port for radio control and the USB port for the rotor interface. I am leaning toward the LVB since the PIC can be programmed and re-programmed onboard, and it can be made into the LVB 2 for stand alone operation without the computer control, although it will be a little more expensive to construct. On the other hand the Satt688 is less expensive, and should suffice as well. How important is it to be able to re-program the pic? All comments appreciated, Thanks, RoD KD0XX A good friend will come and bail you out of jail, A TRUE friend will be sitting next to you saying..... "DAMN THAT WAS FUN"

PCSAT-1 (no-44) In Fine Form!
by VK3MJ 09 Jan '07

09 Jan '07

Just a thought..... With PCSAT-1 returning to life in "full sun" on a regular basis, it would be fun to label each "Return to life" as a cycle #.. Solar cycle maybe? It appears to be around a 3 month period, as it's many fans would know. I easily got several UIs through it at 11:12 UTC 8th Jan. using my hand held (5Watts) and 5/8 vert mobile ant. At a range of 3000 km! Can anyone tell me an easy way to roughly calculate it's next coming? I know I shouldn't be speaking too soon..... Hi Regards Mark VK3MJ Geelong, Australia.

SatPC32 / Rig Blaster / IC 820 H Update...
by sraas＠optonline.net 09 Jan '07

09 Jan '07

I need to slow down and think before I do things... The problem was with the connetcion to the IC820H. For future reference that connection requires a 3.5mm MONO plug ( I was using stereo to no avail ) The cable comming from the Rig Blaster is a stereo.. with both the leads shorted to the tip of the mono plug (Icom Side) and of course both grounded as the norm. SATpc 32 is working well and controling my radio.. I have a great pass on AO-51 from 23:59z to 0012z I will be on pending household duties. -Steve Raas N2JDQ FN20vg

Orbitron question????
by Stargate 09 Jan '07

09 Jan '07

Hi all, I am setting up a satellite station and have been playing with Orbitron for awhile. I like the program allot due to it's being so easy to use. One thing I have not figured out yet is... When a new satellite is launched, such as the RAFT satellite, where do I find it in the program? Under Amateur, Special-interest, Science, ect.... TLE's??? Is it designated a specific category until it goes into it's final TLE?? I hope this makes sense to somebody besides me:-) BTW.... I get my updates from Spacetrak Thanks, RoD KD0XX A good friend will come and bail you out of jail, A TRUE friend will be sitting next to you saying..... "DAMN THAT WAS FUN"

SatPC32 / IC-820H / Rigblaster Plug & Play Help
by sraas＠optonline.net 09 Jan '07

09 Jan '07

Just arrived via ups was my rigblaster plug & play for usb hook up to the IC 820H. I tested it as far as CW goes and i know the interface is working .. but I cannot get it to change the radio frequency for doppler. I have the address right 42H, I have the port right.. port 4.... I just cannot figure out what is goin on for one exception.. and that is I'm using the DEMO version of SatPC32. Until I get my Amsat Member info.. Im not buying it...yes im trying to save 5$ HIHI... does any one use this combo of pc to radio interface? Or is it the demo version does not provide support for rig control? I dident see anything saying such in the documentation. Thanx.. and see u on the Birds -Steve Raas N2JDQ FN20vg

RAFT Command Stations in Southern USA
by Robert Bruninga 08 Jan '07

08 Jan '07

* We need a volunteer command station for RAFT in the * southern states from Arizona through Texas to Georgia Today was the first time I tried to command RAFT from Annapolis to enable the 216.98 MHz radar fence transponder and I timed out 30 seconds before the fence penetration. With RAFT's weak signal, it looks like it would be better to command from a southern state that is underneath the 216.98 MHz transmitter fan beam across the southern USA. With my OSCAR array, I still need a pass better than 15 degrees for success, which is too rare for me to occur while RAFT is passing through the fence. So we need some help. Requirements: 1) an OSCAR array on 2 meters with Preamp or very short coax cable 2) AZ/EL mount and tracking 3) AX.25 standard TNC at 1200 baud 4) Good understanding of basic TAPR-2 TNC functionality 4) any ole' PC that can run a DOS program 5) A recorder to record the downlink audio when RAFT flies through the fence 6) station location from Arizona to Georgia or southern states inbetween 6) persistence and dedication You need access to your station during morning or afternoon passes. Right now they are about 5 PM local time but moving earlier every day by 20 minutes or so. Or you can do the morning passes which are now occuring at about 9 AM local time and moving earlier. What you will do is try to meet one or both of the two passes, and send the command to turn on the RAFT radar fence transponder which will bring up the RAFT 145.825 downlink for about 1 minute which will provide you with the signals heard by the 216.98 MHz uplink receiver. You will record that audio for that 1 minute to capture a ping if it works. Thanks! Bob, Wb4APR

Predict and LVB Tracker
by Howard Long 08 Jan '07

08 Jan '07

Folks I sent a mail out to the BB a while ago regarding an updated version of LVB Tracker I firmware that includes compatibility for use with Predict. I discovered that Predict sent null characters at the start of each command that meant the old firmware got confused and ignored the command. This updated version ignores these null characters, but I'd like to find interested parties who'd be happy to try the new firmware and give it the thumbs up. Let me know if you're interested! 73, Howard G6LVB

AMSAT opportunity for Windows programmer
by Andrew Glasbrenner 07 Jan '07

07 Jan '07

AMSAT-NA has two opportunities available for Windows programmers. We have two projects that are in need of talent, both in support of Operations. This is a great chance to support AMSAT and amateur satellites in a real and tangible way The first project involves writing a GUI XP compatible program to read mixed ASCII and binary telemetry files, extract, reformat, and display the data. Some basic statistics and producing a .csv file are also highly desireable features. Console versions of these programs already exist created in Visual C++ 2005 Studio Express. Support for the finished product will be limited to a few internal users in support of AO-51. The second project involves developing a GUI XP compatible program around some prexisting AX.25 and soundcard code for a UI satellite communications program. Ease of installation and use are high on the priority list for this project, and support will be required for widespread use. A team approach may be best regarding support (read this as "bring a team with you"). This will be done in support of an effort to increase usage and visibility of the several Microsats currently in orbit and functional. Please send a e-mail to ko4ma(a)amsat.org indicating your willingness to help, and I'll be happy to explain further. 73, Drew KO4MA AMSAT-NA VP Operations

PACSAT system
by William Leijenaar 07 Jan '07

07 Jan '07

Hi AMSATs, Due to my qrl I have not so much time and energy to get qrv on the satellites anymore. I am more happy with designing and making new transponders haha... In the last months I finished a new transponder design that is very small in size, relative cheap to produce, good in RF performance, and changeable to other bands. More info will follow later as I am still improving it. Now I have the transponder design I am thinking to make an additional PACSAT system like in UO-22 or KO-25 etc... My main problem is the software, as I am better in RF designbing than in programming (although I will manage some way to make it). I would like to know if there is any software, data or kind of flow chart available from a PACSAT (satellite) system ??? With todays low-power-high-speed processors with lot of memory on chip it should be possible to make a small version of a PACSAT system, isn't it ?? It can be very interresting for balloon missions. Data and pictures can be stored by the OBC and later downloaded by users, like with the WO-18 and GO-32 once was possible. With a battery, solar panels, a box and a rocket we even might have a new satellite :o) 73 de William __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Uni_Trac question
by Bob DeVarney W1ICW 07 Jan '07

07 Jan '07

This is probably a repeat of a recent question, but I just dusted off the sat gear after a hiatus of 2 years, and now have a few quirks. I am using the Uni_Trac 2003 parallel version, and after updating the keps today, I now have an " error in NORAD 2 element file ". I've pared the text file down to the absolute minimum of sats that I will be using, and also removed any extraneous characters that looked out of place ( like the plusses and minuses that have been added in the Celestrak file ) Anybody have a clue what I'm doing wrong? I am also interested in making multiple entries for the same satellite ( AO-51 ) so I can track automatically in V/U, L/S and digital mode, and can't remember how to set that up. I would have posted this to the Uni_Trac reflector, but can't remember the address for it. Thanks and VY 73, Bob W1ICW

Oscar 58 Pass
by Steve Raas 07 Jan '07

07 Jan '07

Hello Everyone . I just received the Oscar-58 beacon on 437.4650 and have a question. I have read abt dopler shift and how It can affect radio signals especially with the sats. This being only the 3rd time ive ever even herd a sat I was shocked to note that the frequency drift was a few Hz lower on every cw note ( the beacon ). It reminded me of an old heathkit HF radio that drifted .. but never settled down. Is this about the normal expected Doppler Shift in a cw/ssb signal on the amsats? I was constantly turning the VFO ever so slightly. Or is this more on par for this particular Sat? Thanx! -Steve N2JDQ

Well as some of you know.. I am in the midst of setting up a small sat station. I received my antennas yesterday, and was up till 3 am building them. I am waiting on my feedlines to come in.. but have been tinkering with the 432 yagi today. I decided to try and strongarm the 11 element yagi in my hand and listen to 435.300. as the bird came up 2 passes ago I herd a brief signal then gone.. I waited till abt 15 minutes ago to try again and WOW AO-51 LOUD AND CLEAR from abt 7deg el to LOS. My kids ran down stairs and wanted to know if that was the ' Space Ship ' I have been trying to hear.. And I replied YES! I have never herd a sat before.. and this was arm chair copy with the yagi in my hand @ ground elevation. I cannot wait to get my feedlines so I can get the final installation done and get a sig on the air. Thank you all for your continued help. -Steve Raas N2JDQ

"Westfest" hamfest in Glendale AZ - 13 January 2007
by Patrick STODDARD (WD9EWK/VA7EWK) 06 Jan '07

06 Jan '07

Hi! I will be part of the AMSAT table at the Thunderbird Amateur Radio Club's "Westfest", at Glendale Community College in Glendale AZ on Saturday, 13 January 2007. The hamfest starts at 0600 local time (1300 UTC) and runs until 1400 local time (2100 UTC). As part of the AMSAT table, I will demonstrate the AO-51 and SO-50 satellites on up to 4 passes during the morning subject to satellite availability: SO-50: 1317-1330 UTC (south to northeast) 1458-1510 UTC (west to north) AO-51: 1509-1522 UTC (east) 1647-1702 UTC (west) Thanks to the hamfest organizers, I am authorized to use the hamfest's special call sign W7W for the demonstrations. I will provide the hamfest with a copy of the satellite log, which will be combined with the log for the HF contacts the hamfest's station makes. QSL information, and more details about the hamfest, can be found at: http://www.w7tbc.org/Westfest.html The grid may not be exotic (DM33), but I hope to work you next weekend from the Westfest. Have a great weekend, and 73! Patrick WD9EWK/VA7EWK - Phoenix, Arizona USA http://www.wd9ewk.net/
