Hi Nate.... I am currently manually forwarding our posts to amsat-bb(a)amsat.org until you get you access. Then the discussion should shift over there. The boards or reflectors will not pass attachments so if you have any, please post on your website and insert URL's for our access. Please point out your antenna location in the pictures you provide.

Thank you very much. I'm in the process of joining those reflectors, but I'm waiting for moderator approval. In your ridge design test I think I would have used the radio with a simple quarter whip to set a baseline for the antenna. This would help isolate your problem by having a 0 dB gain level to your receiving system. Once you set that, you can start testing antennas. >Ah, that's a good idea!

Yes, however use the same connector that is on the radio and have the vertical rod insulated from the outer shield with some sort of plastic sleeve where they "might" make contact.

Remember, you are not in "free space," local objects, height above the ground, etc will skew any true pattern, but it won' hurt to try. I'm not sure how you are deploying such an elaborate antenna without damage during launch and the design is intricate enough that pictures would help. >We have no deplyables.

Without reviewing your EZ-NEC calculations, have you taken into account that the epoxied antenna will be extremely close to the metalic frame and the solar cells? If your antenna is only on one axis will you be shielded in all other directions so that any spin will shadow the earth? Directionality of the antenna comes to mind, interaction with the cube's surface is a consideration. I agree that it is a consideration, but I'm not sure what tools or equations to use to consider them. What about a poor matching circuit? One idea on this side is to try swapping in and out various capacitors to iterate towards a better one. Do you think that would work? I know that the TH-D7 will dial back its power if it sees a high SWR... Many of the Annapolis' satellites used metal tape measure strips rolled up for launch and released into quarterwave whips in orbit as simple antennas. Unfortunately, we don't have this option, since we are spin-stabilized, and antennas that dissipate energy would get us spinning the wrong direction. Having the test transceiver external to the cube for the ridgeline test also brings up some questions as to the duplication of your space cube's actual configuration. We didn't have any electronics in the prototype structure, but we thought having all that metal was enough. We can certainly put the boards in to see if it will have any effect, though. I would suggest setting a direct, line-of-site baseline with a traditional antenna and radio first. I agree, I'm just a little fuzzy on the specifics (see above).

Any feedback on Mirage KP1-440 Preamp?
by Mike Ryan 20 Apr '08

20 Apr '08

Hello all, Zapped my ARR RX only preamp for the second time out of stupidity. Time for a switched model. Cant afford the $200+ amps from SSB and such. The Mirage seems attractive. Can anyone share their experiences with this model or suggest a differnt affordable preamp? I looked at the ARR switched models already. The high powerd mast mount is too much $$ and the low power one only handles 25 watts. I could easily smoke that one out of stupidity as well (my rig can do 50 watts). Mike WB1AAT

Hi Gary, No, I didn't, but the passes before that one were great. Yesterday was for me the 1st time I had time to try AO16. Signals got really strong(er) in the last minutes of a pass. Between 2 downto 0.5 degrees elevation the link was better as between 5 downto 2 degrees. I recall that AO7 145/29mhz mode had the same effect at my station. Kinda good for long distance contacts :-) Anyway, despite that, I 'only' worked other European stations, no Canada or US (OZ1MY, RK3DXB, SP9TTX, G8ATE). MP3 recordings are on my website (http://www.qsl.net/pa3guo under LOGS). But: of course looking forward to some intercontinental QSOs !

This to participate in the development of an educational payload for the maiden flight of the new Vega launch rocket currently scheduled for December. The launch opportunity on the Vega maiden flight is being offered free of charge for up to 6 CubeSats, with an additional 2 backup CubeSats on back up standby. The ESA Education Office says that it recognizes the growing importance of CubeSat projects as a key tool in providing university students with a valuable hands-on practical education across all space engineering disciplines from end-to-end through the complete space project lifecycle. [ANS thanks Newsline for the above information] /EX SB SAT @ AMSAT $ANS-111.04 Cubesat Workshop Presentations Available AMSAT News Service Bulletin 111.04 From AMSAT HQ SILVER SPRING, MD. April 20, 2008 To All RADIO AMATEURS BID: $ANS-111.04 The 5th Annual Cubesat Developers Workshop was held at CalPoly in San Luis Obispo April 9-11 2008.

April 20, 2008 To All RADIO AMATEURS BID: $ANS-111.05 It has been quite a time since the AMSAT-UK European Student Earth Orbiter (ESEO) team have been able to provide an update on the progress of this satellite payload and just recently ESA have made a major change to the structure of the project organization. The plan has been to develop a package to provide downlink telemetry at 400 bps and provide backup tele-command and ranging facilities for the mission management teams. It would, additionally, provide a 435 to 2400 MHz (Mode U/S) linear transponder using both analogue and DSP based systems. ESEO is a 110kg student satellite project intended for launch in to low inclination GTO elliptical orbit. Until the beginning of 2008 the whole ESEO project had been organized directly by ESA Education Office under the SSETI (Student Space Exploration & Technology Initiative) banner but they have now decided to adopt new arrangements. To quote from the ESA website " To date, both projects (ESEO and ESMO) have proceeded in the early phases with a project team consisting entirely of students with project management and ad hoc technical support provided by ESA. It is now intended to implement a new project team structure for these two projects in order to enhance the educational benefits given to the students and to ensure that the project progresses through major reviews to a successful completion on schedule. The new project structure consists of: * a System Prime responsible for the system engineering and technical management of the project, the provision of specialist technical advice to the students where needed, and supervising the student AIV(Assembly Integration & Verification) of the satellite at ESTEC. * a Network of Universities responsible for the delivery of payload items, satellite subsystem items and ground segment systems by their student teams and ensuring the adequate supervision/long-term continuity of the student teams locally." What does this mean for AMSAT-UK's involvement in the project? The launch date is now not expected to be earlier than 2011. The process for the appointment of the System Prime Contractor is presently underway and is expected to be completed by later this year. After the System Prime has been appointed, we will work with them and with ESA Education to ensure that the AMSAT sub-system is available when required by the programme.

AMSAT-Australia and the Ozsatgroup have been working together for more than two years, and have been discussing such an amalgamation for some time. The decision to go ahead with the amalgamation was made after Graham Ratcliff, VK5AGR formally tended his resignation as AMSAT-Australia National Coordinator and as AMSAT Coordinator for the Wireless Institute of Australia (WIA) in his annual report to the WIA 2008 Federal Convention on Monday, 7th April 2008. The role of AMSAT-Australia National Coordinator has been taken on by myself Paul Paradigm, VK2TXT, formally the Coordinator of the Ozsatgroup, and joined by Judy Williams, VK2TJU in the role of AMSAT-Australia Secretary. I would like to take this opportunity on behalf of both the Amateur Radio operators on the AMSAT-Australia mailing list and the members of the former Ozsatgroup to thank Graham for his outstanding contribution to the Amateur Radio community here in Australia and around the world.

Mine have done just that since Xmas, until today. ... I couldn't find my shoulder bag big laptop and so on my way out the door, I grabbed one of the kids XO's so I could try it out for the 5 hours I would be sitting at the kids swim meet. Sitting in the stands, I fired it up, and to my amazement wireless! bingo up came my favorite web pages, and then email. After reading email I went to edit some of my web pages. Flipped the screen around to tablet/book style so that the pages were long and I could read like a book. Holding the device in one hand with the nice finger holes provided. Wow, what a neat way to access wireless, email, web pages, and live mobile APRS. Less than 1/2 the bulk of my big laptop, and only $200 at risk instead of the $1200 labtop. I can't wait for the ham software to start working with it. Talk about portability... The ease of use, will assure that I will now probbly have the ham radio laptop apps with me more often than before since I will be more apt to carry the small XO at low risk then lug the big laptop. I'm sold! And now that my kids see how easy the itnernet access was, I now have to buy my own XO, since now their inteerest has been re kindled and they do want to take them both back to school...

XE83IARU

I just worked XE83IARU- special station and callsign- on VO52. I was unable to determine from the 'net if this is just one or multiple stations. Apparently it is operating April 18-20 in celebration of the 83rd anniversary of the International Amateur Radio Union. Good signal, seemed doppler controlled. Craig N6RSX DM13
