[amsat-bb] Re: Good URL for updating keps HRD

Kevin, If you want the most recently available Keps for the ISS, or anything else not classified, it is worth getting a free account at Space Track. www.space-track.org They feed pretty much everything else, and update 3-5 times a day. More if needed. I don't recall the last time the

[amsat-bb] 5500 rotor problem

Starting to put my satellite system back on the air. Now having another rotor problem. I think what happened is that after Hurricane Irene passed by, everything was working. Later that morning a surprisingly strong wind gust after Irene passed by blew my sat array over. I was unaware of this and

[amsat-bb] G5500 Elevation Rotator Short Circuit?

I wonder if this is a known fault. Recently the fuse on my G5500 blew. The problem seems to be a short on one of the motor circuits. Checking the DC resistance at the control end, the resistance of one winding is 1.2 ohms, whereas all the other windings are 4.6 ohms. I could understand a

[amsat-bb] Re: G5500 Elevation Rotator Short Circuit?

The common failure of the motor windings is caused by heat which causes the enamel coated wire to breakdown. When the enamel breaks down an inner winding short results. I have successfully rewound motor windings on these rotators just to say it could be done, but it takes some work (not

[amsat-bb] Re: 5500 rotor problem

Ok I started working the problem tonight. I would first like to thank, Al Wa4sca, Stan W1le, and Jeff N3qo, for some ideas on what the problem might be. What I found so far is an open between 4 5 and 6. Any combination of the three is open. So I'm assuming I burned out the motor windings in the

My 5500 has had a 450 motor in it for about 8 years :) It was cheaper to buy a used rotor than the motor from yaesu parts. 73, Drew KO4MA Sent from my iPhone On Oct 7, 2011, at 8:34 PM, Jeff KB2M k...@comcast.net wrote: Ok I started working the problem tonight. I would first like to thank,
