Another question at what North or South latitude is a grid square, square? Art, KC6UQH I don't think they are EVER really square because longitude lines are never really parallel. They approach square/parallel at the equator, but they are always going to have only the two sides defined by latitude lines parallel (what's that, a rhombus?). And at the pole the north and southmost squares are actually triangles, no? So I would say if you are standing at the pole, unless you have infinitely small feet and can really stand exactly on the pole, the number of grid squares you are in depends on how wide your feet are and how far apart they are when you are standing :-) Fun questions!

Dear Amsat members. could you please tell m what is the difference between telemetry data satellite is in normal mode and when in detumbling mode? I know some thing about telemetry data of satellite for space communication board. that teir voltage and power transmit to ground in 0.1 Hz. I mean this rate how change in detumbling mode?

Hi! I would like to thank all involved with the AMSAT Symposium. I had a great time! It was fun meeting new friends. Yes, thanks to the San Jose crew for putting on a great Symposium! Nice to see old friends, and to put faces to several voices I've heard on the satellites in the past few years. It was great to see - and hear - the OSCAR I model that was on display, and mix in a little bit of operating from outside the hotel and also from Santa Cruz on the coast. 73!

[amsat-bb] Re: Radar Echos Asteroid YU55
The BAA Radio Astronomy Group have issued the following bulletin: Yesterday evening (UK time) astronomers using NASA's Deep Space Network antenna in Goldstone, California captured new radar images of Asteroid 2005 YU55 approaching the Earth. The images were taken about 19:45 UT on November 7 when this very dark object was still some 3.6 times the distance of the Moon away. Details can be found at: http://www.nasa.gov/mission_pages/asteroids/main/index.html http://www.nasa.gov/mission_pages/asteroids/news/yu55-2007.html NASA scientists will continue to track 2005 YU55 for at least four hours each day until November 10. Radar observations from the Arecibo Planetary Radar Facility in Puerto Rico will begin on November 8. The object will make its closest approach to Earth on November 8 at 23:28 UT at some 324,600 km or 0.85 the distance from the Moon to Earth. Although UK observers are well placed to watch the last few hours of its approach, the weather prospects here are pretty dire for the entire country. However there are two 'live' broadcasts being organised via the Slooh organisation which you may be interested in. Details are at the Slooh website / Twitter at: http://events.slooh.com http://twitter.com/#!/Slooh In particular, two radio shows are planned for November 8th/9th, the first at 21:00 UT will hopefully show live images of 2005 YU55 using the Slooh Half-Metre telescope on Mount Teide, Tenerife, weather permitting; the second, at 02:00 UT (on the 9th) will be using Slooh's partner's 24 telescope based in Arizona. Both shows will be hosted by Bob Berman of Astronomy magazine. Dr. Robert McMillan (2005 YU55's discover) will be appearing as a guest during the first show. There is a possibility that, as the BAA's Asteroids and Remote Planets Section Director, I may also take part on the first radio show from 21:15 UT.

[amsat-bb] Frustrated...need detumbling program.
The subject line is meant to be facetious, however, I am experiencing much frustration and my brain (what ever is left up there) is tumbling when it comes to decoding the cubesats that were deployed on Oct 28. I have been decoding the telemetry from ARISSat-1 without any problems. I have copied and recorded SRMSAT. I have had QSOs on AO-7. I have digi'd through ISS. I even had a nice QSO with Mike Fossum last week. BUT, I can not decode any of the telemetry from RAX-2, M-Cubed, or E1P. I hear them but just can not see anything using HyperTerminal or the designated Decoding software. I only have the Internal TNC in the TS-2000 and the SignaLink USB/AWGPE. I did try an old MFJ-1270B but it is not able to do 9k6 with its internal modem. I don't know how to tune them in using USB.The mode is stated as FSK or Non-Coherent FSK. I was told to use USB but the signal sounds awful. I know there are a few of you who are copying them. Maybe it is my ignorance or lack of experience, or maybe it just takes more sophisticated equipment. It just seems to me that if the amateur community is being asked to help with these projects, then it should be less complicated to do so. I have pretty much given up on them and put all my effort now into ARISSat-1 while it lasts. If anyone can come down to my level and give me some advise without being so matter-of-fact about it, I would appreciate it. If I just can't do it with what I have, then tell me, so I can stop wasting my golden years trying to be a rocket scientist or space cadet or whatever.

[amsat-bb] Re: video from ISS
Hello Trevor...an amateur fastscan would be popular but seen by almost no one (grin)...a 5ghz link would be technically challenging. other then a good 2/10 and 2/70cm transponder on ISS what I would advocate is a slight improvement over the APT system used in weather sats and pushed down by packet..that would be very popular and quite doable by ordinary hams. I think I know how they are going to get the video down...we just installed a system in a Gulfstream sized airplane...that allows live video on one of the satellite systems with a reasonably small antenna (hint it fits on the T Tail top)we can do live video conferencing in 45 degree banks (grin)...doing the flight test on it now..the people who are selling it claim they are getting ready to put one on Ivans side of the station. I believe that claim after what they showed me today. 73's Robert G.
