[amsat-bb] Re: ISS keps
The ISS did some thruster tests recently. That could account for the difference. ISS is a dynamic satellite. It has minor and major changes to its orbit and the predicts are sometime a bit behind the actual until things fall into a more stable state and get updated. I expect the numbers will be off again after the Soyuz undock today (tomorrow UTC).

Today issue is better, however, still actual ISS posn about 100 miles ahead of SatPC32's displayed posn. My computer clock is off by no more than 1 second. For the clock to throw posn off by 100 miles, clock would need to be in error by about 15 seconds. Just create an account at http://www.space-track.org/ and download the keps from there. I just logged into Space Track, and they have an ISS element set that was updated at approximately 2053 UTC today (not long before I sent this message). Regardless of the freshness of the elements, it sometimes takes a little bit after the ISS has a boost raising its orbit to where the keps are back to being on the mark. 73!

[amsat-bb] Fw: KR500 bearings
Hi Bob W7LRD My previous message to you via w7...@comcast.net was rejected to me ! 73 de i8CVS Domenico - Original Message - From: i8cvs To: Bob- W7LRD Sent: Thursday, September 23, 2010 4:36 PM Subject: Re: [amsat-bb] KR500 bearings - Original Message - From: Bob- W7LRD To: i8cvs Sent: Thursday, September 23, 2010 1:13 AM Subject: Re: [amsat-bb] KR500 bearings Hi Domenico-I am putting everything back together. A couple of questions. Do you find some grease may ooze out when it gets warm? Hi Bob W7LRD You should apply any type of black grease normally used over the outside gears of crains machine wich widstand high temperature without to melt. As the retainer ring which has a little lip seems to hold the grease inside. It is correct but if you use 2 or 3 more balls then the retainer is non anymore necessary. Also I loosened the little gear wheel that drives the pot, in order to work the gear train. You must buy a new one gear wheel ! It is a little trickey to get to, is that pot only 180 degrees or can it go further? No... the original pot can rotate for more than 360 degrees I will have to tighten the gear back to the pot shaft when I can get the pot in the right location. I don't want to accidently run to rotor and keep going at the end of the pot. The original 500 ohm pot can rotate all around for more than 360 degrees and the center pot wiper of the new model of rotators has a flexible wire outside the case of the pot to provide a safe contact inside of it ! 73 Bob W7LRD Best 73 de i8CVS Domenico - Original Message - From: i8cvs domenico.i8...@tin.it To: Bob- W7LRD w7...@comcast.net, AMSAT-BB amsat-bb@amsat.org Sent: Tuesday, September 21, 2010 8:26:11 AM Subject: Re: [amsat-bb] KR500 bearings - Original Message - From: Bob- W7LRD w7...@comcast.net To: amsat-bb@amsat.org Sent: Tuesday, September 21, 2010 1:54 AM Subject: [amsat-bb] KR500 bearings Hi-I am looking for a supplier of bearings and the support for them for the KR500 el rotor. I called Vertex and they're not sure if the bearings are the same as the current 5400/5500 series. The Kenpro product line is no longer in production. 73 Bob W7LRD Seattle Hi Bob, W7LRD The diameter of each ball for the bearing of a KR500 is 0.312 or 5 / 16 inch or 7.9375 mm. I suggest you to remove both stainless steel bearing holders throw it away and add 2 or 3 more balls in each bearing in order to replace the room of the holders teeth. I did it but I do not remember exactly if I added 2 or 3 more balls. Fill the bearing wrinkles of the rotor housing with black dense molibdene grease and pull the balls in it.It works very well for me from many years now. 73 de i8CVS Domenico ___ Sent via amsat...@amsat.org.
