FO-29 problem?
by SV1BSX 20 Apr '07

20 Apr '07

Hi all, today afternoon during #52710 orbit over East Europe, I heard nothing from FO-29. My effort to access the Satellite was also without success. Anybody noticed that? (or my UHF receiving system is faulty?) 73, Mak SV1BSX __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Re: Best arrangemet and best distance

Hi Nader, Place the VHF and UHF antenna as far away from one another as possible on the cross boom. That way you get the smallest problem with desensing when you transmit on VHF and receive full duplex on UHF. Place the two other antennas in between the two large ones. I use a 3 meter glass fiber cross boom this way and it works fine. Also make sure you have mechanical balance in your system to avoid unnecessary torgues on the rotators. >From a point of view of distorting the radiation pattern, you can place the antennas very close to one another as long as they do not touch one another. Place the VHF and UHF antennas in X so that the elements are not parallel to the cross boom. 73 OZ1MY Ib ----- Original Message ----- From: "nader omer" <st2nh(a)yahoo.com> To: <amsat-bb(a)amsat.org> Sent: Friday, April 20, 2007 4:44 AM Subject: [amsat-bb] Best arrangemet and best distance Hello all I would like to know what the best arrangement and the best distances between vhf cross yagi antenna uhf cross yagi antenna l-band helical antenna s-band helical antenna over a one cross boom 73 de Nader -st2nh --------------------------------- Ahhh...imagining that irresistible "new car" smell?

Thank you Pedro, but that's not the question. We are trying to use these TNCs with our own protocol. Not AX.25. They work fine using AX.25 and KISS. But in KISS they will not pass our non-AX.25 protocol. The SPIRIT works fine with our protocol. So we are looking for clues as to how to get them to work in KISS with a protocol that is simply data wrapped in flags.

Re: Re^2: CAPE-1 CW heard !
by Mineo Wakita 19 Apr '07

Thanks for many suggestions. Yes, P-POD A, B, C are the old predictions. so I could hear CW in the early stage after the launch. But CW can't hear any longer by these keps. The most recent keps will be available from NORAD, Space_Track, or W0RPK's page. --------------------------------------------- Name: Mineo Wakita / JE9PEL, JAMSAT member Mail: ei7m-wkt(a)asahi-net.or.jp URL : http://www.ne.jp/asahi/hamradio/je9pel/ QTH : Yokohama Japan, GL:pm95tj Date: Apr 19, 2007 ---------------------------------------------

Re: CAPE-1 Tracking
by Jonathan Wagner 19 Apr '07

Matt, I haven't received any reports from the 0610 pass. It was going to be a max elevation of 1 or less at our ground station. The two passes before that AOS was about 4 minutes behind #31126 and probably 30-60 seconds behind P-POD C keps from the launch. Tracking P-POD C kept the antenna's main lobe just ahead of the sat. As far as the workshop is concerned, most of the team is in California as of last night. The original team members, me, Wade and Shawn will not make it.
