I've been following this project with great interest. US Paypal users may have issues logging on to Paypal via the link on the webpage (I did), but I sent it to the address at the top of the page from a US Paypal log-on. Maybe someone from -ZL could tell us if that worked from their end. 73 and Merry Christmas, Drew KO4MA

KiwiSAT - Not just another one!
by Terry Carrell 24 Dec '07

24 Dec '07

KiwiSAT; we're building it for you! Did you enjoy using the Phase-3 satellites? Remember the UoSATs? Are you using some of the current units? Over the years AMSAT-ZL has contributed some $10,000 to these programs and are now quietly getting on with completing KiwiSAT for your enjoyment. ( See http://www.kiwisat.org ) We want this to be a truly radio amateur satellite and while we could get some extra sponsorship, which we will do for the launch, the satellite itself needs to be completed using amateur radio resources and amateur radio money. So far our investment is some US$15,000 cash and perhaps US$100,000 in time and effort. We have a further US$12,000 in the bank reserved towards the cost of the solar cells (US$30,000 est.). We spend a lot of time looking for economy without engineering compromise thus this is a real cost effective satellite. We have abandoned purchasing ready made modules and opted for self design and construction. Yes, some areas we have had to use professional services, for instance our SMD handing ability is limited by our standard ham-shack tools and techniques. However we have made much of the test equipment ourselves - including the thermal vacuum chamber. To finish the satellite to flight-ready status, (less solar cells) we need to raise some $10,000, which is about what we have given to other projects. So if you agree that its pay-back time, and you like what we are doing, perhaps you might like to contribute to this venture into space. You can contribute large or small, direct or via PayPal, just visit our informative website at http://www.kiwisat.org, all help is greatly appreciated. Be assured your contribution will be thankfully received and faithfully applied. Our grateful thanks to those who have already made a commitment to supporting this project. KiwiSAT: A Microsat scheduled for launch into a LEO, will carry FM and Linear transponders with inputs on 70 cm & 23 cm - outputting on 2 metres. A unique feature will be the on-board Small Satellite Attitude Control scientific experiment. It will also carry a special environmental/global warming scientific unit. What a great time to help and what a great Yuletide gift to a worthy cause. Thanks for reading, and best wishes for really enjoyable amateur radio in 2008. Terry, ZL3QL. President AMSAT-ZL.

Good Morning and Merry Christmas all: As of the 1212z pass over FN02, ANDE is still sending good telem, and is still able to digipeat. Amazing. John KB2HSH -- _______________________________ John Marranca, Jr PBX Technician/Shop Steward CWA Local 1122 BN Systems, Inc Orchard Park, NY (716)972-2006

Re: ANDE Temperature rising !
by Henk, PA3GUO 24 Dec '07

Hi Stefan, I based the temp rise on the graphs in http://web.usna.navy.mil/~bruninga/andeTLM1.html (BAT A and LASER A) which now show a modest upwards curve. But: you are right, using the SW of Mike shows indeed no (significant) increase. Thanks for correcting ! Henk > Hi Henk, > > I am not sure where you see the increase in temperature.

Hi Andrew for sure its essential to be able to switch polarization sense or at least switch between vert and horiz if you don't have a phasing harness. I myself use a polerphazer at the shack end which means bringing two lengths of coax into the shack.Regards Robert G8ATE > From: vk4tec(a)people.net.au> To: amsat-bb(a)amsat.org> Date: Mon, 24 Dec 2007 13:39:58 +1000> Subject: [amsat-bb] Crossed yagis> > What is the best way to set up phased crossed yagis ?> > Have an electric coax switch in the middle to switch from left to right circ> polar ?> > > > ----------------------------------------------------------------------------> Andrew Rich VK4TEC> vk4tec(a)people.net.au> http://www.tech-software.net> > > _______________________________________________> Sent via AMSAT-BB(a)amsat.org.

RS-22 a bit poorly
by Chris Bloy 24 Dec '07

24 Dec '07

Hi All, Decoded RS-22 this morning on the 09:00 GMT pass and it would appear that the voltages are fine, she decided to send “RS22 UBS” “RS22 long tone....” “TTXA tone.......” “RS22 UBS 139 IBS32 TTXA111 TTXA110 tone” I have recorded the pass and it would appear that there was 0 volts & amps on the solar battery. Anyone else manage to decode it? It was also moving into the eclipse north of me to visit Santa, so this could be that the batteries are starting to fail? There was 13.9v and current of 0.32mw being drawn, which is normally 0.02mw.. Anyway, have a good Christmas and would be interested in anything with one of the last RS Satellites in space!

Hi Andrew, Last month I made a 2x6 elements DK7ZB: http://home.vianetworks.nl/users/hamoen/pa3guo/dk7zb.html PE1ITR made a prototype of a polarization switch based on: http://www.sm5bsz.com/polarity/simplesw.htm Those two together work fine. See the report on my DK7ZB web description (URL above). In the coming weeks I will built my own switch based on the same concept of SM5BSZ. After that I will put some pictures and measurements on the web, but the SM5BSZ web is a pretty good source. Succes Henk, PA3GUO http://www.qsl.net/pa3guo
