[amsat-bb] Re: OSCAR-11 Heard!
Hi Another very strong UO-11 pass here this evening. (0909 to 0922 utc, 60 deg) The signal became noisy with rapid fading just after UO-11 went into eclipse at around 0919 but signals continued but gradually became weaker and the fades deeper until I lost the signal in the noise about 1 minute before LOS. I recorded the pass. 73 Alan ZL2BX -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Clive Wallis Sent: Sunday, 22 November 2009 17:41 To: amsat-bb@amsat.org Subject: [amsat-bb] OSCAR-11 Heard! Hi, I have received two reports from Keith N4ZQ (EL88ob) that he has heard UO-11 on 19 November at 13:33 - 13:43, and on 22 November at 13:02 UTC. He has sent me a WAV file of the second pass.

The same problem occurs when controlled by computer from Uni_trac 2000. Work about 25% of the time. Mike kb8zgl Hi Mike, KB8ZGL Connect an AC voltmeter between A4 and A5 on rear of control box and check if there is 24 volt AC when the rotator sticks. If you have 24 volts when the rotator sticks connect an amperometer in series with A4 or with A5 and check if the AC current flows as soon the rotator sticks. If the current flows when the rotator sticks probably the internal AC 100 uF capacitor is defective or you have a mechanical problem inside the reduction gear or into the ball bearing holder of your rotator If you have a 100 uF AC capacitor in the junk box connect it across A4 and A5 and try again to see the effect. If you don't have an AC capacitor you can buit it by your self using two electrolitic capacitors each 200 uF 250 volt DC and two diode 1N4007 or equivalent connected as per the following schematic diagram: - + + - |) |--|--| (| A4-| | |---A5 |---||--|--||| 1N4007 1N4007 If the rotator sticks and if the AC current don't flow you probably have e limit switch SW6 or SW7 defective poor contact and high resistivity between contacts. Disconnect A4 and A5 from control box and using an ohm-meter check the continuity of the motor windings If one winding of the motor has a fail contact then your ohm-meter will jump measuring the capacity of the AC capacitor. This is what I would do easy and fast in your situation. Have fun 73 de i8CVS Domenico ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Future scheduling of SO-67
Hello Given that the SA-AMSAT payload on SO-67 is shared with the satellite back-up TTC transponder, there is unfortunately not a way to keep the payload switched on permanently, or even semi-permanently. For the lifetime of the satellite we will therefore have to do with active scheduling. In an effort to make this as painless as possible, I would like to request comments on the possible use of regional coordinators, which I believe worked quite well for SO-35. Such coordinators would then be responsible for setting up schedules in advance for their specific regions, taking into account obviously the pool of possible satellite passes, as well as local events / fairs etc. We would then simply load the schedules on a weekly basis. Up 'till now I have mainly focused on Europe, RSA, South America, North America / Canada, Japan and Australia / NZ. I would like to invite suggestions for use of the payload over other regions as well. This adds to the previous point. Regarding possible activation at night: this is entirely possible, but would have to be planned / managed more actively, given the power limitations in eclipse. We have yet to experiment with this and see what the available capacity would be.

I heard the old familiar buzz loud and clear on a Yaesu FT-530 HT and a hand held three element Yagi on the 1453 UTC pass over Fort Worth, TX, this morning. It was certainly good to hear the old familiar buzz and it reached full scale on the FT-530 during a good part of the pass. 73 - Keith, W5IU ___ Sent via amsat...@amsat.org.

I was the VK/ZL coordinator for SO-35, and drew up the schedule for the region for over a year. If I recall correctly, I was the first of several regional coordinators. The arrangement worked well, and I formed a close working relationship with the SO-35 team. The work wasn't particularly difficult, and having local knowledge, I could tweak the passes to suit the needs of the local satellite community. I also helped the SO-35 team test different transponder configurations (some worked better than others), by offering feedback about how well the different configurations worked, using my setup of known performance. Based on my experience, I would recommend and encourage the use of regional coordinators. It's not a particularly difficult job, it takes the load off the satellite operators, and it provides a local point of contact for satellite users to request passes for special events, or to cover areas that were missed out. 73 de VK3JED / VK3IRL http://vkradio.com ___ Sent via amsat...@amsat.org.

Hi Drew, Yes I know how fustrating it was in pre-ISS days when the Shuttle was launched into low inclination orbits - little chance of hearing it up in the northern countries such as the UK. But it should give Amateurs in many developing countries a chance to to work the sats using simple equipment and those countries are the future for Amateur Radio. It's really encouraging to see that the Indonesian national society ORARI and AMSAT-ID have been so successful in working with their national space institute.

During that EVA the first task is to install two antennas on the Columbus Module. One is for an experiment for the European Space Agency and the other is a dual band 2m/70CM antenna for ARISS (Amateur Radio on ISS) very similar to the antennas already on the Russian service module. If you have any way to watch, I am sure it will be exciting for any ham to watch. This is an example of what can be achieved by volunteer hams working closely with a space agency. This antenna project was funded entirely by AMSAT-NA and volunteers who built the antennas for both the experiment and for ARISS. That's not to take away from the tremendous contribution from ESA for the experiment, the launch and the EVA. I have no idea what that cost but you can be assured it was a lot more than the cost of the antennas. Once the antennas are in place we will be working to bring amateur radio to the Columbus module. I am very proud of all the teamwork and effort that has gone into this project. Lou McFadin W5DID ARISS US Hardware manager ___ Sent via amsat...@amsat.org.
