IRENE Is Coming
by Doug Kuitula 24 Aug '11

24 Aug '11

Hi All, It looks like you hams on the east coast of North America, from North Carolina to Quebec and Nova Scotia, are going to have some problems with antennas this weekend. I hope you have had time to take down the towers and have made the proper plans. I hope we will hear you with a hand held antenna and an HT. I was just thinking if any hams have any health and welfare communications via satellite in the next weekend. Do we have any procedures that we should use on the birds? And are there any procedures that should be used on the digital satellites? Quite obviously do not break up any emergency communication while on the birds. Just wondering anyway..................73 de Doug KA8QCU

Aluma Tower and Yaesu G5400 Azimuth Rotor
by Joe Leikhim 24 Aug '11

24 Aug '11

Hi; I am in the market for an Aluma Tower T-40H, I found one which needs a few parts and DLC, (anyone else selling similar in Florida, speak up). My question is the installation of the G5400 azimuth rotor. I didn't have the tower and rotor in same place at same time, so I made up a 7 1/2" diameter template simulating the bolt hole placement and outer "corners" of the bolt bosses on the rotor bell. It seems that it "might just fit" with about 1/16 inch uncertainty. Has anyone else installed this rotor inside of an Aluma Tower T-40H? Some say it interferes with fully retracting with some rotors. Experience good or bad, please share. Thanks -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida www.Leikhim.com JLeikhim(a)Leikhim.com 407-982-0446

The thing is launches are done by human beings and humans do get sloppy at times or turn a blind eye to short comings because they believe with good reason that if they don't they won't get promotion or may even be sacked. Submarines have the advantage of never exploding less than a minute after leaving harbor. > I know that its a big deal to say "space is hard" and that excuses > all sorts of things including mediocrity or failure to follow > established technical procedures and guidelines. Yes in space mediocrity or failure to follow established technical procedures and guidelines kills - for most earth bound activities people can get away with it most of the time. When we look at the video of the deployment of ARISSat-1, were the Cosmonouts deliberately knocking the satellite against the ISS structure or was maneuvering a satellite in a weighless environment very difficult? Thinking back about the deployment it doesn't suprise me that it was the 70cm antenna that broke off. The 2 meter antenna is big and conspicuous so you'd try your best to ensure it didn't hit anything. The 70cm antenna is small, inconspicuous and on the opposite side of the satellite to the 2 meter antenna that you're taking care not to knock - result the 70cm antenna is the one that gets clobbered. 73 Trevor M5AKA
